New Phycitiplex Porter (Hymenoptera, Ichneumonidae) from Subandean Desert in northwest Argentina
(2008)
Six new species of Phycitiplex (P. obscurior, P. tricinctus, P. unicinctus, P. peralta, P. trichroma, and P. lepidus) are described from material taken by Malaise trap in a humid ravine at Santa Vera Cruz in the Subandean Desert (Monte) of La Rioja Province (Argentina). These are keyed along with several closely related described species. Except for P. eremnus from central Chile, this genus is known only from the semiarid Chaco and Subandean biogeographic provinces in the northern half of Argentina. The only available host record is of Phycitiplex doddi (Cushman) reared from larvae of Cactoblastis cactorum (Berg), a phycitid moth that attacks prickly pear cacti.
1.1 Introduction 1.1.1 Aim of project .To compare the abundance of invertebrate and weed seed food resources available to birds on orzanic and conventional farmland. The objective of the studv was to assess accurately the likely benefit of these farming systems to birds feeding on farrn'land, by sampling invertebrates and weed seeds. 1.1.2 Factors implicit to achieving the project aims Variation between farms within one system could influence' invertebrate or weed seed abundance and bias results, To minimise such effects and provide results 'representative of the farming systems as a whole, sampling was based on an extensive approach; farms were sampled in groups. The inference that either of the farming systems is beneficial to feeding birds is dependent on: (i) prior knowledge of the relevance of a particular invertebrate or seed as a food-source: evidence (ii) that this foodsource is present in sufficient abundance and (iii) that the food-source is readily accessible, The methodology described below was refined to address these criteria. 1.1.3 Methodology Sampling concentrated on cereal crops, with an additional comparison of organic grass ley fields at a limited number of sites. Sampling initially consisted of sucking invertebrates from the crop using a vacuum insect net and extraction from soil cores. To aid the interpretation of results from this sampling, it was decided that more information was required on the diet of birds. This was achieved by analysing faecal sacs for undigested fragments of invertebrates that therefore represented a dietary component. Skylark chick faecal sacs were chosen for analysis as this was the key species for the intensive ornithological studies and samples could be taken during routine fieldwork. As a result of this study, the main invertebrate sampling technique was changed to pitfall traps, since this was a superior method for assessing those invertebrates found to be important food-sources. It was also anticipated that pitfall trapping would provide more accurate estimates of invertebrate availability, with greater numbers per sample, than the previous two techniques. Studies of weed seed food resources consisted of field surveys using a quadrat to assess the presence and abundance of species, and the use of a small hand held suction machine to suck seeds from post-harvest stubble. The interpretation of the results emphasised the aspects of the ecology of species known to be food-sources that might influence their availability to birds. 1.2 Soil core and vacuum samples 1.2.1 Significantly more dipteran immature stages and Coleoptera were found in soil cores on organic grass ley fields and significantly more earthworms on organic cereal fields than conventional cereal fields. Earthworms and dipteran larvae such as tipulids are known to be important food-sources for birds that specialize in soil invertebrates. 1.2.2 Total numbers of invertebrates trapped by both methods did not differ significantly between the two farming systems. Significantly more invertebrates were trapped, however, by both methods on organic grass ley fields than either conventional or organic cereals. 1.2.3 Significantly more Staphylinidae tCol.), especially the species Tachyporus hypnorum, were found on conventional fields, The relevance of this species as a food-source is, however, doubtful. 1.2.4 The weevil Sitona lineatus and the carabid Demetrias atricapillus were found in significantly greater numbers on organic fields. The former may constitute a food-source for skylarks, which have been shown to feed on this insect under laboratory conditions. 1.3 Faecal sac analysis 1.3.1 Carabid beetles were an important component of skylark chick diet, forming 47 % of identifications. In some cases it was possible to identify the species present. 1.3.2 Coleoptera, other than carabids, from the families Elateridae, Curculionidae, Chrysomelidae and Staphylinidae were identified as food-sources. 1.3.3 Spiders and tipul ids were also important components. 1.3.4 Reservations are expressed that the technique may under-represent soft-bodied invertebrates, which are susceptible to complete digestion by skylark chicks. 1.4 Pitfall trap samples 1.4.1 Twelve key species of carabid beetles were analysed. of which five cornmon species were trapped in significantly greater numbers on organic farms. These were Pterostichus melanarius (the dominant species captured), Pterostichus madidus, Harpalus affinis, Harpalus rufipes and Nebria brevi collis. The other species analysed showed no significant variance between farming systems. 1.4.2 Williams' Index of Diversity was significantly greater for conventional fields, although caution is expressed over the reliability of this result due to the small sample size of species. 1.5 Botanical studies 1.5.1 The abundance of weed plants in quadrats was significantly greater on organic fields. 1.5.2 The abundance of weed seeds was not significantly different between farming systems. However, the relative proportions of monocotyledonous and dicotyledonous seeds in samples differed between farming systems. A larger proportion of the seeds from organic fields were dicotyledonous and from conventional fields were monocotyledonous. 1.5.3 Preliminary examination of the size of plants and the number of seeds produced suggested that those on organic fields may have been nitrogen deficient. 1.5.4 Weed species were significantly more diverse on organic fields. although diversity has less relevance to bird feeding than abundance. 1.6 Proposals for future work 1.6.1 Replication of the pitfall trapping exercise in subsequent years would substantiate the trends established from the data of one season. It would also be beneficial 10 extend the range (If habitats sampled to take into account set-aside and other crops besides cereals. 1.6.2 More comprehensive information. on the diet of farmland birds in general. could he achieved by analysing the faecal sacs of a wider variety of species. 1.6.3 Greater integration of field studies on birds with invertebrate sampling would enhance the effectiveness of the latter as an indicator of diet. Areas of farmland frequently selected as feeding sites by birds could be sampled intensively for invertebrates and compared to other areas, selected at random. This would provide useful information on the invertebrates likely to be important as food-sources and the habitats that favour them. 1.6.4 Extending the range of farms sampled would provide more accurate results. 1.6.5 More work is required to-investigate the possible link between nitrogen deficiency in plams and organic systems, and its implications for the provision of bird food-sources, particularly for weed abundance and phytophagous insects.

Plant names in Yiddish
(2005)
Yiddish linguist Dr. Mordkhe Schaechter confronts the stereotype that "there aren't any plantnames in Yiddish” with the meticulously researched, long-awaited Plant Names in Yiddish, to be published by YIVO in August 2005. This groundbreaking Yiddish-English botanical dictionary draws on literary, scientific, linguistic and religious sources to document a wealth of Yiddish plant names - including many dialectal and regional variants. It is an essential reference work for Yiddish speakers and readers, scholars, researchers, culinary and nature enthusiasts, historians, scientists, and linguists. Plant Names in Yiddish is a fascinating study not only in botany, but also in the development of the Yiddish language as reflected in botanical vocabulary. For example, Schaechter cites Yiddish terms for willow: sháyne-boym, noted in the writings of Mendele Moykher-Sforim and A. Golomb, (from hoysháyne >hesháyne >sháyne - 'willow twigs used ritually on the holiday of Sukkoth'). He also notes that Yiddish terms for the halakhically appropriate vegetable species for a Passover seder have been documented since at least the 12th century, and that "'potato' is regionally known as búlbe, búlve, bílve, kartófl(ye), kartóplye (!), érdepl, ekhpl, ríblekh, barbúlyes, zhémikes, mandebérkes, bánderkes, krumpírn, etc. One town in Galicia, Sanok, at a crossroads of languages and cultures, boasts five different synonyms for 'potato; such examples display the richness of the Yiddish language and its regional diversity. Several important reference sections designed to assist the reader are incorporated into the book, including the English-Yiddish dictionary of botanical terms and plant parts, which provides many words not available in the standard Modern English-Yiddish Yiddish-English Dictionary by Uriel Weinreich. The Trilingual Latin-English-Yiddish Taxonomic Dictionary section helps those who may know a word in one language to find it in another. An extensive index (including a geographic index) makes searching easier, and there is a detailed source bibliography. There are many cross-referenced variations of plant words in Yiddish, a useful tool given the diversity in spelling, dialect and region. A special section on orthographical and morphological variations is also included.

Appendix * Abbrevations * Bibliography * Rhyme Tables of Early Middle Chinese (600) * Rhyme Tables of Early Mandarin (1300) * Word Index o English o Pinyin In 1786, just over two hundred years ago, comparative historical linguistics was born, when Sir William Jones (1746-1794) discovered the relationship between Old-Indian Sanskrit, Greek, and Latin. Since then, the emerging Indo-European philology has thrown much light on the early history of mankind in Eurasia. During the past two hundred years, many suggestions were also made in regard to relationships of Indo-European to other languages such as Semitic, Altaic, Austronesian, Korean etc., but Indo-Europeanists commonly rejected such attempts for want of convincing evidence. As to Chinese, Joseph Edkins was the first to advance the thesis of its proximity to Indo-European. In his work China's Place in Philology. An Attempt to show that the Language of Europe and Asia have a Common Origin (1871) he presented a number of Chinese words similar to those of Indo-European. In his time, Edkins' thesis seemed bold and extravagant. But today, more than a hundred years later, we are in a much better position to carry out a comprehensive and well-founded comparative study. Since the end of the nineteenth century, many Sinologists have been engaged in reconstruction of the mediaeval and archaic readings of Chinese characters. Among them, Karlgren (1889-1978) was the most successful, and in 1940 he published a comprehensive phonological and etymological dictionary entitled Grammata Serica. In the meantime, the Indo-Europeanists Alois Walde (1869-1924) and Julius Pokorny (1887-1970) were devoting themselves to the compilation of a useful etymological dictionary. The result was the Indogermanisches Etymologisches Wörterbuch by Pokorny (1959) which provides a solid basis for our lexical comparisons. Soon thereafter, some Sinologists made use of the two dictionaries by Karlgren and Pokorny to compare Chinese and Indo-European words. In 1967, an unaffiliated German scholar, Jan Ulenbrook, published an article "Einige Übereinstirnrnungen zwischen dem Chinesischen und dem Indogermanischen", in which he claimed that 57 words are related. Shortly afterwards, Tor Ulving of the University of Goteborg, Sweden, wrote a review of this article framing the title as a question: "Indo-European elements in Chinese?" While working on his thesis on word families in Chinese, Ulving compiled for his own use two dictionaries: "Archaic Chinese - English" and "English - Archaic Chinese", and discovered thereby 238 Chinese words similar to Indo-European roots. In spite of this considerable number of word equivalents, however, Mr. Ulving became discouraged and, as he told me in his letter of April, 1986, has given up his researches in this field. The skepticism, common among Indo-Europeanists in regard to comparative studies with other languages, is largely based on the dogmatic opinion that only morphology is relevant but not vocabulary. Since the typology of Chinese seems to preclude a cognate relation to Indo-European, they are inclined to discard any lexical correspondences as merely accidental or onomatopoetic. Besides, prehistorical contacts and mixtures between these languages seem not conceivable, as the Indo-Europeans are supposed to have originated in Northern Europe or at best in the Central Asian steppe, thousands of miles away from East Asia. Hence, any research into a relationship between Old Chinese and Indo-European languages would be but futile from the outset. Yet there are also opposing views among Indo-Europeanists. Investigations into Germanic languages and the oldest Indo-European language, Hittite, led some of them to a critical revision of the prevailing conception about a Proto-Indo-European. Hermann Hirt (1934) for instance states: "Inflexion of Indo-European languages is due to a relatively late development, and its correct comprehension can be achieved only by proceeding from the time of non-inflexion." And Carl Karstien (1936) holds the opinion that "Chinese corresponds most ideally to the hypothetic prototype of Indo-European." Regarding vocabulary, there are striking similarities in the monosyllabic structure of the basic words. In modern German and English, all the words of everyday speech are monosyllabic and their stereotypical structure is: initial consonant(s) + vowel(s) + final consonant(s). The same word structure is valid for Chinese as well. It is fundamentally different from the disyllabic structure of Altaic words and from the triconsonantal-disyllabic structure of Semitic words. Characteristic of the monosyllabic word structure is, besides, the complexity of the syllable nucleus, which consists of different vowels and vowel clusters in contrast to the monophthongal vocalism of polysyllabic words. Another objection raised to comparisons between Chinese and Indo-European is the existence of tonal accents in Chinese. Since most modern Indo-European languages have only expiratory accents, Chinese is considered to be a highly exotic language. Yet, even in Chinese, the use of tonal accents as a means of lexical differentiation is a result of comparatively recent development in the long history of Chinese language, the earliest monuments of which date back to 1300 B.C. (cf. Chang 1970, p.21). Unknown to Old Chinese, the existence of tonal accents was for the first time mentioned in the 5th century by Shen Yüeh (441-513). In Middle Chinese (Mch.) there were four tone categories: A P'ing-sheng 平 a level tone (which developed into Mandarin tone 1 or 2). B Shang-sheng 上 a rising tone (Mandarin tone 3). C Ch'u-sheng 去 a vanishing, i.e. falling tone (Mandarin tone 4). D Ju-sheng 入 an entering tone with a staccato effect, the word being abruptly stopped by a final consonant -p, -t, -k. (In Early Mandarin the words of this tone lost their final consonant and were distributed among the tones 2, 3 and 4, respectively according to the phonation of initials). In Middle Chinese, words of the entering tone were the only group which still preserved the final stops and therefore a close syllabic structure. So they are most appropriate for convincing comparisons with monosyllabic Indo-European word stems. The final stops -p, -t, -k of the entering tone are nowadays still extant in daily speech of several dialects in South China as well as in Chinese borrowings in Japanese, Vietnamese and Korean. As a speaker of a Taiwan dialect of Minnan origin, I could immediately identify some Indo-European stems with corresponding Chinese words. Besides, the command of Japanese and German was also a great help for this study. In the following lists I have chosen a number of Indo-European stems which are phonetically and semantically equivalent to Chinese words. Correspondences in initial and final consonants refer to the points of articulation, thus we have equations: IE labials = Old Chinese labials, IE dentals = dentals, IE l, r = dentals (cf. p. 31); Ø, i (final and medial) IE velars = velars and laryngeals, and occasionally (the so-called "satem"-forms) IE velars = dental sibilants and affricates. Regarding the manner of articulation, there are no regular correspondences between Indo-European and Chinese consonants like Grimm's law which is valid among Indo-European dialects to a certain extent. But this is not astonishing, since in Old Chinese the alternation of initials in voicing was a conventional means of creating new words from one basic form. The rules of vocalic correpondences among Indo-European dialects are quite complex. Vowels permanently change their qualities from one language to another, and from time to time within one language also, as is well known from the history of English pronunciations. Generally, the vocalism of Old Greek is taken as the standard for Proto-Indo-European. Old Chinese vowels corresponds nearly (cf. p. 30), but the details about the reconstruction of Middle and Old Chinese vocalism will be treated later (pp. 26-30). For the moment, it is necessary to notice in advance that the stem of ablauting Germanic verbs is the form of preterite or noun, rather than that of infinitive as assumed hitherto. Therefore, in some cases I must slightly modify the basic vowel of verbal stems given in Pokorny, in order to get better basis for comparison. As Old Chinese verbs were non-flexional, they might probably have preserved the original vowel the best.
At the outset of this dissertation one might pose the question why retroflex consonants should still be of interest for phonetics and for phonological theory since ample work on this segmental class already exists. Bhat (1973) conducted a quite extensive study on retroflexion that treated the geographical spread of this class, some phonological processes its members can undergo, and the phonetic motivation for these processes. Furthermore, several phonological representations of retroflexes have been proposed in the framework of Feature Geometry, as in work by Sagey (1986), Pulleyblank (1989), Gnanadesikan (1993), and Clements (2001). Most recently, Steriade (1995, 2001) has discussed the perceptual cues of retroflexes and has argued that the distribution of these cues can account for the phonotactic restrictions on retroflexes and their assimilatory behaviour. Purely phonetically oriented studies such as Dixit (1990) and Simonsen, Moen & Cowen (2000) have shown the large articulatory variation that can be found for retroflexes and hint at the insufficiency of existing definitions.
The morphology of green and blue feathers of the Rose-faced Lovebird (Agapomis roseicollis) is described from light-, fluorescence-, and electron microscopical findings and discussed in relation to earlier works. The description is intended to provide a basis for future comparative studies. Special attention is given to the colour-producing elements (pigments and the short-wave reflecting spongy structure ('Blaustruktur', 'cloudy medium') of specialized medullary barb cells (spongy cells, box cells)), and the findings are correlated with macro- and microspectrophotometric measurements. Green barbs differ from those of blue ba rbs in having their cortex yellow pigmented, but are further distinguished by their spongy structure which is denser (wider keratin rods and correspondingly narrower air-filled channels) than that of blue barbs. This difference corresponds to the wave-length of maximum reflectance being shifted c. 30 nm towards longer wave-lengths compared to that of blue barbs. Thus green barbs are not the same as blue barbs only with a yellow pigmented instead of an unpigmented cortex, as usually stated. Dark green hack feathers reflect approximately half as much light throughout the visible spectrum as do green belly feathers. This difference is due to variations in yellow and black pigmentation of the barbules. These variations are described quantitatively and the importance of barbules for the resulting feather colour is stressed. Variation in size and shape of barbs and barbules are discussed, principally in relation to their optical efIects and the presumed functions of the colours. The colour produced by the spongy structure cannot be explained by Tyndall (Rayleigh) scattering as is usually done. This follows from the shapes of the barb reflectance spectra which are not in agreement with the Rayleigh equation (scattering inversely proportional to lambda4). A new model for colour production is forwarded. It is based on a model of the spongy structure in which this is considered to consist of short hollow keratin cylinders (diameter 0.3-0.35 ft) with air-filled cores. Backscattering from these cylinders is considered responsible for colour production and good agreement is obtained between values of lambda max calculated from the model and those measured spectrophotometrically. The backscattering from the Individual cylinders can be regarded as an Interference phenomenon. The colour of the spongy structure thus is an interference colour. That it appears diffuse and not iridescent, as is generally the case for interference colours in feathers, is due to the presence of many hollow cylinders oriented in all directions in the spongy structure.
The Chanukah omission
(2008)
Aristotle argued over 2000 years ago that it was legitimate to resist tyranny, yet he provided no arguments as to which means were legitimate. Until today, although we still cannot agree in defining legally what activity can be characterized as “terrorism,” we can all repeat the famous words, “I can’t define it but I know when I see it.” Most important, we all feel the need to explain it and finally combat it. Yet human bombs, this fashionable weapon of today’s terror campaigns, pose an extra difficulty, as they are perceived by many as most difficult to prevent and repel: how can someone actually stop and deter a person who is not afraid of giving up life? The appearance of women in this kind of murder activity has complicated the question, as their gender makes it quite difficult to detect let alone understand them, due to existing images and perceptions about the female role in society and crime. Usually security services, policymakers, and analysts have little conceptual understanding of how the factors contributing to terrorism, as well as the various social parameters, actually affect the individual terrorist. Instead they seem to believe strongly that hard-line policies will prevent terrorism because terrorists want to avoid high costs. The prescriptions dictated by this approach are quite attractive, because they are conventional, compatible with the existing political doctrine, and relatively easy to implement. Few efforts have been made thus far to devise an analytical framework for understanding the processes and factors that underlie the development of the suicide bomber and the execution of suicide bombing attacks, and even fewer about the female actors. Yet to date the approach has contributed little in combating suicide terrorism, where the perpetrators clearly are oblivious to the physical cost of their actions. If multiple factors are likely to underlie any one observation, this undoubtedly applies to suicide terrorism, which is a complex phenomenon not caused by one single factor and not to be adequately explained by one overarching motivation. In order to understand it there is a need to appreciate the ethnic, religious, political, social, and economic context in which it takes place. If perceived as a crime, then any factor that affects or concerns the perpetrator also has to be analyzed in order to break down the pattern of deviance and deter it adequately. Gender is one of these crucial factors, so the female participation in suicide terrorism merits special research, since the cultural, social, and religious standards in the terrorism arenas put women in a very different position than that of men. They are “special” deviants, not because the operational method of their self-immolation differs from that of men, but because their womanhood plays a key role in the way the whole social environment influences them. It is the specific province of criminology, which involves studying the manifestations of crime and social control in relation to law as well as the conditions, processes, and implications at the societal level, that Criminological Perspectives on Female Suicide Terrorism contributes to identifying and analyzing female suicide attacks. Thus, criminology can offer valuable explanations to the formidable goals of counterterrorism, which in turn will be better able to try to combat or modify the special characteristics of this form of female criminal behavior.
The meaning of chains
(1998)
This thesis investigates the mechanisms applying in the interpretation of syntactic chains. The theoretical background includes a translation of syntactic forms into semantic forms and a model theoretic explication of the meaning of semantic forms. Simplicity considerations apply to all three stages of the interpretation process: syntactic derivation, translation into semantic forms, interpretation of semantic forms. Three main results are achieved. The first is that trace positions can have semantic content beyond what is needed for the semantic dependency of trace and binder. This extra content is some or all of the lexical material of the head of the chain, as expected on the copy theory of movement. Two independent arguments support this conclusion. One, discussed in chapter 2, is based on the distribution of Condition C effects, where novel interactions between variable binding, antecedent contained deletion and Condition C are observed. The second, developed in chapter 3, is based on conditions on the identity of traces observed in antecedent contained deletion constructions. Both arguments lead to the same generalizations about what lexical material of the head is interpreted in the trace position. The second main result is that lambda calculus is superior to both standard predicate logic and combinatorial logic as the mathematical model for the semantic mechanism mediating the dependency of trace (or bound pronoun) and binder. Chapter 4 argues this on the basis of the distribution of focus and destressing in constructions with bound pronouns. The third main result is that quantification must be allowed to range over pointwise different choice functions. Chapter 5 shows that quantification over individuals is insufficient, and that pointwise different choice functions are required. The result entails that the syntactic difference of A-chains and A-bar chains predicts a semantic difference in the type of the variable involved, which is argued to explain weak crossover phenomena. Chapters 6 argues that the interpretation procedures developed in the preceeding chapters account for all cases. It is shown that only traces of the type of individuals arise, and that scope reconstruction is a phonological phenomenon. The latter result also supports the T-model of syntax.

The Bay of Diego-Suarez, considered to be one of the finest and largest natural harbours in the world, is located towards the northernmost tip of Madagascar in the Antsiranana province. Despite its historical and current use as a port, much of its convoluted perimeter is still somewhat untouched, harbouring pristine shorelines and subtidal coral reefs. The position of the bay between other regions in which high marine biodiversity has already been revealed suggests that it may also harbour high biodiversity. However, the relatively long coastline and limited connectivity of the bay with the Indian Ocean, in combination with existing anthropogenic activities, potentially make its marine environments susceptible to a range of environmental impacts including sedimentation, nutrification and pollution. The Frontier-Madagascar Marine Research Programme (FMMRP) became involved in conducting marine ecological survey work in the Bay of Diego-Suarez, north Madagascar, in April 2005, having relocated from its previous base at Anakao in southwest Madagascar. The rationale for the survey programme stemmed from the affiliation of the FMMRP with the Malagasy organisations Association Nationale pour la Gestion des Aires Protégées (ANGAP) and Service d’Appui a la Gestion de l’Environnement (SAGE), who were interested in identifying areas of the bay with particularly healthy coral reef systems. Additional environmental interest in the bay has arisen as a result of its proximity to surrounding terrestrial protected areas such as the newly managed Ramena complex, incorporating Orangea and Montagne des Français, and also Montagne d’Ambre. Since its relocation to the Diego-Suarez area, the FMMRP has compiled over two years’ worth of marine ecological data relating to benthic community composition, fish species abundance and population size structure, frequency of algae and invertebrate indicator species, and physical environmental parameters. Thus there exists an extensive dataset for the Bay of Diego-Suarez, from which details of the current condition of its marine habitats can be investigated and a baseline for temporal monitoring can be established. The primary purpose of this report is to signify the initial detailed dissection of the dataset and demonstrate the conclusions that can be made regarding the ecological status of coral reef systems within the bay. This has mostly involved the examination of benthic data, focusing upon variations in percentage cover of substrata and coral community characteristics as useful structural indicators of reef condition. Additionally, the report includes an assessment of the abundance and distribution of sea urchins and their relation to benthic community patterns, as a demonstration of the ability to interrelate different aspect of the FMMRP dataset to enhance the conclusions that can be drawn. Benthic community data were obtained from 380 line intercept transects conducted in different sectors of the Bay of Diego-Suarez between October 2005 and December 2007, representing a combined distance of 7,600 m. Sediment occupied the greatest overall proportion of the benthos (around 38%), especially in the western areas of the bay. Overall mean hard coral cover was around 15%, and tended to co-vary with other ‘hard’ substrata such as rock and rubble. In total, 38 scleractinian coral genera were recorded during survey work, in addition to a number of unidentified genera. The coral communities of the bay were dominated by Acropora and Porites spp., which comprised around 33% and 20% of total recorded hard coral cover, respectively. Hard coral cover and generic diversity appeared to be positively related. These indicators were greatest in the northeast area opposite the mouth of the bay, reaching mean values of around 37% and 6.8 genera, respectively. Here, the hard coral community was dominated by Acropora spp. and comprised a relatively high proportional cover of Galaxea spp. In the northwest of the bay, coral cover was approximately half as great and consisted primarily of species belonging to the genera Porites and Millepora. Habitats in this area were highly similar in terms of their overall coral community composition. Hard coral cover and diversity were generally lower in the southern portion of the bay, especially in more immediate proximity to the population centre of Diego-Suarez (around 2% and 1.5- 5.5 genera, respectively). Coral community composition was considerably more variable than in the northern portion of the bay. v After sediment and ‘hard’ substrata, seagrass formed the next major interplaying component of the benthic environment (around 10% overall proportional cover). The easternmost areas adjacent to the mouth of the bay were characterised by high seagrass cover, whic h reached around 48%. Little or no seagrass was encountered elsewhere, except at one locality in the northwest (around 13% cover). Macroalgae cover was low and less variable, reaching a maximum value of around 10% adjacent to Diego-Suarez. There were no differences between island and mainland sites in terms of overall benthic substratum characteristics, yet soft coral cover was significantly greater amongst island sectors. Sea urchin abundance data were obtained from 498 belt transects conducted between April 2006 and December 2007, representing a total area of 49,800 m2. A total of 6 species were recorded, of which Diadema setosum comprised by far the greatest relative abundance (96%) and observation frequency (55%). The greatest population densities of this species were encountered in the more exposed areas in the west and northwest, reaching around 1.5 m-2, and very few individuals were recorded in the eastern reaches. Data suggest a possible seasonal increase in D. setosum densities, corresponding with an increase in water temperature towards the end of the year. No significant correlation existed between D. setosum population density and coral cover, although these seemed to be inversely related in the central northern area of the bay. There was also no significant correlation with macroalgae cover. However, D. setosum density was positively and negatively associated with rubble and seagrass cover, respectively. There was a lack of a clear pattern amongst sectors with respect to overall benthic community characteristics, let alone between the density of D. setosum and benthic substratum composition. In conclusion, a relatively detailed map of benthic community composition has been produced for the Bay of Diego-Suarez, which shall be useful in elucidating the primary factors determining the condition of marine environments within the bay and developing effective sustainable management strategies. Further analysis, incorporating additional components of the FMMRP dataset, is required in order to further clarify our understanding of the key issues surrounding the current status of these coral reef systems. It is hoped that continued survey work will enable important long-term ecological monitoring of the marine environment of the bay and assessment of the effectiveness of any management initiatives that may be implemented.

Four MA dissertations and 222 BA research essays are listed alphabetically, and indexed by reference number under three subject categories-geographical area (by district, etc.), ethnic group, and a general subject index of 42 headings. All but 31 of the 226 alphabetical entries contain research solely on Botswana: the other countries being South Africa (12 entries), Zimbabwe (11), Namibia (6), Angola and Zambia (1 each). The most researched district of Botswana is Central (54 entries), followed by Kgatleng and Kweneng (25 each), North-East (24), South-East (16), Southern (9), Ngamiland (6), Chobe and Ghanzi (3 each), and Kgalagadi (2). The subject index of 29 ethnic groups ranges from Afrikaners (2 entries) and Amandebele (2) through Babirwa (7), Bakalanga (24), Bakgatla (27), Bakhalagari (4), Bakwena (21), Bangwato (19), Basarwa (5), and Batlharo (1), to Indians (3) and Ovambanderu (2). The general subject index ranges from Administration (29 entries), Agriculture (18), and Archaeology (21), through Biography (28), Cattle (7), Chieftainship (27), Class formation (7), Councils (7), Economic development (23), Education (14), and Heritage management (7), to Labour and labour migration (7), Medicine (4), Nationalism (13), Religion (15), Serfdom, servitude and slavery (7), Settlement history (19), Trade and commerce (13), Trade unions (6), and Urbanization (15). With the notable exception of one MA dissertation, there is a lack of cultural studies which may partly be attributed to research being done instead under the aegis of other departments in the Faculty of Humanities.
Northern Chile, which includes the extremely arid Atacama Desert and the semiarid Andean Highlands, has more than 100 basins with interior drainage; most contain salars (salt-ilncrusted playas). The area of interior drainage totals more than 38,000 square miles, within which salara and clay playas extend over a total area of about 2,800 square miles. In addition, hills and valleys in the Atacama Desert are extensively covered either with a thin hard saline crust, chiefly salt-cemented soil, or with a powdery soil that has a high content of saline material, chiefly anhydrite and gypsum. The region has an exceptional variety of types of hard saline crusts that are generally rare in other deserts, and many morphological and structural salt features, some of which may be unique. Soft saline crusts and clay playas, more characteristic of arid regions elsewhere, are also present. Hard salar crusts have formed by deposition of saline material in open water or by capillary migration and evaporation of near-surface ground water. Such crusts generally range from a few inches to several feet in thickness. Locally, crusts may attain thicknesses of several tens of feet, and one salar, Salar Grande, is a basin filled with high. purity rock salt to a local depth of at least 560 feet. Six general types of hard salar crusts are distinguished: (1) layered massive rock salt with a rugged surface, (2) slabby or nodular silty rock salt, (3) rugged gypsum or anhydrite, (4) massive coarsely crystalline rock salt, (5) smooth rock salt, and (6) silty nitrate-bearing saline crust. Soft surfaces or crusts include moist gypsum-bearing crusts, which commonly contain nodules and layers of ulexite in Andean salars, and moist to dry puffy soils and crusts that contain gypsum, thenardite and mirabilite as the principal saline constituents. An unusual chemical feature of the salars and the desert soils of northern Chile is the general paucity of carbonate minerals (for example, trona, calcite, and aragonite) which are widespread in other desert regions. Among the many morphological and structural features that can be recognized in and near salars of northern Chile, the most unusual occur in hard rock-salt crusts, which in themselves are scarce in other arid regions. Included are features due to corrosion of rock-salt crusts by windblown water or free-flowing surface water, such as: (1) salt cusps and crenulate margins of salars, (2) salt channels, (3) salt pseudobarchans, and (4) salt tubes. Constructional features in the salars include: (1) gypsum buttresses at borders of saline ponds, (2) salt veins, (3) salt stalactites, and (4) salt cones. In some salars, new fresh-water springs have formed steep-walled brine pools in thick rock-salt crusts. Prominent salt cascades and constructional salt terraces have been built up in one Andean valley by springs that are fed by brine from a nearby salar (Salar de Pedernales). Sag basins and prominent scarps occur along faults that cut through the salt mass of Salar Grande. Of, the 67 closed basins in the Andean Highlands of northern Chile, at least 35 show shorelines or deltas of former perennial lakes. Today only flve perennial lakes occur in this area. The former lakes probably formed at one or more times during the Pleistocene and perhaps continued to form into Holocene time. They indicate a climate that was either more rainy or cooler, or both, during the time of their formation. However, the absence of glacial features throughout most of the northern Chilean Andes indicates that the climate during the Pleistocene glacial stages was not greatly different from today's climate. It is estimated that perennial lakes would form in nearly all thil Andean basins if the mean annual rainfall of the region above 10,000 feet in altitude were increased to 15 inches from its present 8 inches, and if the mean annual temperature were about 2° F. less than it is at present.

This regional study documents the life and the destruction of the Jewish community of Magdeburg, in the Prussian province of Saxony, between 1933 and 1945. As this is the first comprehensive and academic study of this community during the Nazi period, it has contributed to both the regional historiography of German Jewry and the historiography of the Shoah in Germany. In both respects it affords a further understanding of Jewish life in Nazi Germany. Commencing this study at the beginning of 1933 enables a comprehensive view to emerge of the community as it was on the eve of the Nazi assault. The study then analyses the spiralling events that led to its eventual destruction. The story of the Magdeburg Jewish community in both the public and private domains has been explored from the Nazi accession to power in 1933 up until April 1945, when only a handful of Jews in the city witnessed liberation. This study has combined both archival material and oral history to reconstruct the period. Secondary literature has largely been incorporated and used in a comparative sense and as reference material. This study has interpreted and viewed the period from an essentially Jewish perspective. That is to say, in documenting the experiences of the Jews of Magdeburg, this study has focused almost exclusively on how this population simultaneously lived and grappled with the deteriorating situation. Much attention has been placed on how it reacted and responded at key junctures in the processes of disenfranchisement, exclusion and finally destruction. This discussion also includes how and why Jews reached decisions to abandon their Heimat and what their experiences with departure were. In the final chapter of the community’s story, an exploration has been made of how the majority of those Jews who remained endured the final years of humiliation and stigmatisation. All but a few perished once the implementation of the ‘Final Solution’ reached Magdeburg in April 1942. The epilogue of this study charts the experiences of those who remained in the city, some of whom survived to tell their story.
I conducted an 18 month study on the behavior and ecology of two species of sympatric caviid rodents (Kerodon rupestris and Galea spixii) in northeastern Brazil. Preliminary observations indicated that Kerodon was a habitat specialist. occurring only in large boulder piles. whereas Galea appeared to be a habitat generalist. occurring in a variety of open habitats excepting the boulder piles inhabited by Kerodon. This situation presented an ideal field experiment to compare the social structures in these two closely related genera. I first established breeding colonies of both in order to describe their behavioral displays and to discern their function. Complete behavioral repeltoires. including vocalizations. are presented for both Kerodon and Galea. Reproduction and growth. behavioral development. sexual behavior. agonistic behavior. and use of space were all examined both quantitatively and qualitatively in the colonies and in the field. Time budgets were calculated and analyzed for both genera. Differences in rates of growth and behavioral development between the two genera afe probably related to ecological aspects of their significantly different microhabitat preferences. Data on sexual and agonistic behavior collected in the colonies suggested that Kerodon exhibited resource defense polygyny, whereas the Galea mating system approximated male dominance polygyny. Field data supported the colony observations. These differences in mating systems may be related to the different habitat preferences observed. Kerodvll is compared to other resource defense polygynists. Finally, a model for the evolution of behavior in the family Caviidae is presented. The social organizations of the various genera seem to be very responsive to ecological requirements. The importance of social organization in ecological adaptation is discussed.
Twelve genera, two of them new, are recognized in the tribe Adesmiini in southern Africa. Four new species of Epiphysa, one of Alogenius (placed in a new subgenus), two of Stenocara, one of Metriopus, and one placed in one of the new genera, are described. The genera are revised, and their distribution and relationship are briefly discussed
