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.
