Das Untersuchungsgebiet und seine Gewässer werden beschrieben und die Ergebnisse ungefähr zehnjähriger Sammeltätigkeit für vier Ordnungen aquatischer Insekten zusammengefaßt. Die Nachweise von 68 Steinfliegen, 157 Wasserkäfern und 173 Köcherfliegen werden in Artenlisten aufgeführt. Für eine Reihe ausgewählter Arten werden neben den faunistischen Angaben einige taxonomische, zoogeographische und ökologische Hinweise gegeben. Von den Eintagsffiegen werden 39 Taxa besprochen. Eine Steinfliegen- und sieben Köcherfliegenarten sind neu für die bayerische Fauna; Crunoecia kempnyi MORTON und Prolonemura austriaca THEISCHINGER wurden erstmals für Deutschland nachgewiesen.
Beitrag zur Kenntnis der Wasserinsektenfauna Nordwest-Hessens : 1. Köcherfliegen (Trichoptera)
(1992)
Bei meinen Untersuchungen über die Algenflora Lettlands habe ich bisher einigen Gruppen weniger Aufmerksamkeit widmen können; es sind das besonders die farblosen Monaden und die Chrysophyceen. In den letzten Jahren habe ich von Zeit zu Zeit, unter anderen Arbeihm, nach Möglichkeit auch diese zwei Gruppen beachtet. Selbstverständlich setzt das die Untersuchung von lebendem Materiale voraus und womöglich gleich nach dem Einsammeln, da viele in Frage kommende Formen beim längeren Stehen der Proben sehr bald eingehen und verschwinden; an ihrer Stelle treten danach einige verbreitete Saprophyten und andere ubiquitäre Monaden in Vordergrund: Vielfach erwies es sich auch nötig, um die Entwicklungsgeschichte einzelnen Typen einigermassen lernen zu können, mit isolierten Hängetropfkulturen zu arbeiten,was jedoch meist nur dann möglich war, wenn die Monade für die Isolierung in etwas reichlicherer Menge vorlag. Nun konnten die meisten gefundenen Formen der Rhizomastigaceen, Monadaceen und Bodonaceen, sowie die Mehrzahl der untersuchten Eugleninen nicht mit den schon bekannten Arten identifiziert werden. Von den unten berücksichtigten 12 Cyanophyceen, 125 Flagellaten im engeren Sinne, 1 Kalkflagellate, 8 Peridineen und 14 Volvocineen, insgessamt etwa 160 Arten (incl. einiger Varietäten), erwies sich die reichlich grösste Hälfte als neu.
Aus Bequemlichkeitsgründen habe ich auch in diesem Teil meiner Beiträge vorläufig noch die frühere Gruppeneinteilung beibehalten, obwohl diese unseren gegenwärtigen Kenntnissen über die verwandschaftlichen Beziehungen innerhalb der Protisten nicht völlig entsprechen.
Es werden auch 8 neue Gattungen beschrieben. Davon gehört Parabodo zu den Bodonaceen, Kathablepharis und Spiromonas zu den Cryptomonadalen, Gyropaigne und Protaspis zu den Eugleninen, endlich Aulacomonas, Gyromitus lmd Hemitoma zu den Volvocineen. Drei von diesen repräsentieren
meines Erachtens zwei besondere Familien - die der Kathablepharitdaceen und Protaspidaceen.
Baltic Sea
(1957)
La famille des Pyuridae n'est représentée en Nouvelle-Calédonie que par onze espèces, la plupart vivant dans les zones portuaires. Une seule espèce est nouvelle, Bolteniopsis pacificus, qui vit dans des sables grossiers et représente la première espèce de ce genre trouvée dans le littoral tropical. Les Molgulidae ne sont représentées que par une espèce nouvelle.
Dix-neuf espèces de Styelidae, pour la plupart coloniales, sont décrites ou signalées du lagon. Huit sont nouvelles. Sur les onze espèces connues, neuf sont présentes en Australie. Quatre espèces ont une repartitlon tres vaste couvrant dans certains cas toutes les mers chaudes. Les espèces nouvelles appartiennent toutes à des genres dont la diversité maximale est en zone tropicale.
Quinze espèces dont deux nouvelles pour la Science ont été récoltées en Nouvelle-Calédonie. La plupart d'entre elles sont aussi connues de l'Australie et de l'Indonésie. Une seule espèce est considérée comme faisant partie d'une faune tempérée australe. Toutes les autres sont d'affinités tropicales.
Quinze espèces d'ascidies Phlébobranches ont été récoltées dans le lagon de Nouvelle-Calédonie. Elles appartiennent à quatre familles: Corellidae, Ascidiidae, Perophoridae et Cionidae. Cette dernière n'avait pas encore été signalée de cette région. Quatre espèces sont nduvelles pour la science: Diazona textura (Cionidae), Ascidia dorsalis (Ascidiidae), Ecteinascidia aequale et E. koumaci (Perophoridae). Seules cinq espèces (une Corellidae et quatre Ascidiidae) étaient déjà connues de Nouvelle-Calédonie.
Arthropods inhabiting the sporophores of Fomes fomentarius (Polyporaceae) in Gatineau Park, Quebec
(1971)
The fauna of the sporophores of the perennial bracket fungus Fomes fomentarius (L. ex Fr.) Kickx were examined in a 3-year study. One species of molluscs and more than 152 species of arthropods excluding mites, representing 13 orders, 70 families, and 5400 individuals, emerged from or were found on or in, 1448 sporophores detached from dead birch trees; the sporophores were collected each year in Gatineau Park, Que., kept individually in screen-topped glass jars in a laboratory, and examined for several months. Mites, which were recorded quantitatively only in the final year, added 4 orders, 19 families, and 30 species to the preceding totals. Mites were the most frequently occurring and probably the most numerous arthropods, followed by Coleoptera, Psocoptera, Collembola, Hymenoptera, and Diptera. The key organisms of the fauna were five species of beetles that were primarily responsible for tunnelling and destruction of the sporophores and would therefore exert great influence on the composition of the community. Their tunnels provided shelter and food for many smaller arthropods or facilitated their feeding. Some beetle species tunnelled the sporophores for one season and others, for several, but many living sporophores and most dead ones tunnelled by beetles were tunnelled in the same season by more than one species of beetles. There was considerable latitude in types of sporophores inhabited by various arthropods but some species were particularly attracted to living or dead, to younger or older, and to smaller or larger, sporophores. Some species were also attracted to certain regions of the sporophore more than were other species. Possible economic implications of observations made in the study are discussed.
Araneae : cinquième série ; précédée d'un essai sur l'évolution souterraine et son déterminisme
(1931)
The regular or obligate aphytophagy of certain lycaenid butterflies (Lepidoptera) is discussed within the framework of the most recent general classification of the family. A summary survey of all Lycaenidae known to be aphytophagous is presented, together with a brief account of cannibalism and other opportunistic aphytophagy exhibited by normally phytophagous butterflies. The range of food sources (plants, animals, excretions and regurgitations) exploited by lycaenids is reviewed with emphasis falling on the ecology of myrmecophilous early stages and the significance of their ant-related adaptations. Adult feeding and oviposition behaviour reveal further associations with ants. Specificity oflycaenid/ant relationships and the possible biological effects ofaphytophagy on the Lycaenidae are discussed. Finally, speculations concerning the evolution of aphytophagy by these bulterflies are critically presented.
Analyse morphologique du splanchnocrane chez les primates et ses rapports avec le prognathisme
(1956)
Chez les Mammifères inférieurs, les mâchoire et les cavités orbtitaires sont situées en avant du neurocrâne; chez les Primates, le massif facial se déplace et est en partie situé sous la cavité cranienne; chez l'Homme, non seulement le massif facial est réduit de volume, mais il est logé entièrement sous le neurocrâne. ...
Phytosociological syntaxa of North and Central Anatolia were reviewed almost at all categories and discussed from some methodological viewpoints. Totally 178 diumallepidopteran associations, inhabited on various vegetational units from planar to alpin zone were studied for the first time. The possibility of the application of some phytosociologica1 methods for the Lepidoptera associations were investigated. The selection of the character-species of the higher lepidopteran syntaxa, and the aspect concept, as well as importance of the distribution pattern in biogeography for the character-species to be selected were discussed. Faunistically, 334 diurnal species in 25 lepidopteran families were recorded. Among them, four species and one genus are new to the fauna of Turkey. Each species recorded were also investigated autoecologically. Their habitats were described using the phytosociological syntaxa, as well as the plant formations. Habitat preferences of the species were evaluated. Vertical and horizontal distributions, abundances, phenology, and food-plants of the adult stages were listed. Species recorded in various plant formations and vegetational units were given in separate lists.
A survey of the freshwater fishes of the Sepik River system of northern Papua New Guinea was undertaken by the authors between 1978 and 1985 with the use of gill nets and rotenone, and also by monitoring catches at local villages and markets. We also include records of past expeditions, namely that of the Dutch naturalist Gjellerup in 1910 and the yacht Illyria in 1929. The total known freshwater fauna as reported herein consists of 57 species in 35 genera and 23 families. The fauna is typical of other sections of New Guinea and northern Australia in that it is dominated by catfishes (Ariidae and Plotosidae), rainbow fishes (Melanotaeniidae), gudgeons (Eleotrididae) and gobies (Gobiidae) which collectively comprise 57 percent of the total species. With the exception of 22 widely distributed species that are frequently estuarine dwellers and are confined to the lower Sepik, the fishes are strongly endemic, either to the Sepik-Ramu drainages (which interconnect during Doods), or the "intermontane trough" composed of the combined Markham, Ramu, Sepik, and Mamberamo systems. Individual accounts, including brief descriptions and information pertaining to habitat, distribution and biology are included for each species. In addition illustrations are provided for many of the endemic species.
The objects of this work were to reinvestigate and extend the results announced in a brief note published in 1925 (Murray and Huxley, 1925a). In this paper it was concluded that isolated fragments of the limb buds of the fourday chick are able to self-differentiate when Iiving as grafts on the chorio-allantoic membrane of older chicks; that the bud of the four-day chick is a mosaic; it was hinted that each of the morphological regions of the limb (femur, tibia-fibula, etc.) is represented by a Single piece of the mosaic; that no regeneration or regulation occurs in fragments of the bud, except that it was concluded that if a grafted fragment contains only part of a piece of the mosaic, that part could so regulate its future development as to form the complete morphological region of which it was originally a part, so that a fragment of the bud which contains part only of the region Which would normally form femur will, when growing as a graft, form a complete femur. It will be seen that the results of the present work uphold and confirm the tentative conclusions previously advanced, except in regard to the last point (regulation). A considerable amonnt of further information has also been obtained bearing on tile factors concerned in the development of the form of bones and joints.
An annotated list of Ecuadorian butterflies (Lepidoptera: Papilionidae, Pieridae, Nymphalidae)
(2001)
The A. A. present in this paper their studies about the Aspergillus spp. found by them as contaminants of Lab. cultures, chiefly. The species studied are the following: A. allocotus n. sp., A. amstelodami, A. awamori varo hominis n. var., A. candidus, A. fischeri, A. flavus, A. heteromorphus n. sp., A. japonicus, A. niger (two strains), A. ochraceus, A. ochraceo-petaliformis n. sp., A. quadrilineatus, A. repens var. ramos a n. var. A. sclerotiorutn, A. sydowii, A. terreus, A. unguis and A. variecolor var. major n. var.
In this paper eight tribes (Gyrophaenini, Placusini, Homalotini, Diestotini, Falagriini, Athetini, Lomechusini, and Oxypodini), 19 genera and 42 species are recognized. Four genera (Brachyglyptaglossa n. gen. [Homalotini], Trisporusa n. gen., Daccordiusa n. gen. [Lomechusini], and Antistydatusa n. gen. [Oxypodini]) and 37 species are described as new. Each new genus and species is illustrated. Placusa fauveli Pasnik, 2001, from Sydney, is placed in synonymy with Placusa tridens Fauvel, 1878, from Sydney. A new combination to Spallioda for Calodera carissima Oliff is proposed.
Aeration in higher plants
(1979)
A taxonomic revision of the genus Syntrichia Brid. (Pottiaceae, Musci) in the Mediterranean Region and Macaronesia has been carried out, thus contributing to knowledge of its distinguisliing morphological characters, geographic distribution and nomenclature. Some 3000 specimens, including the most of type material, were studied. An identification key, morphological descriptions, photographs and numerous observations on taxonomic and nomenclatural problems of the 23 taxa accepted in the study area, are provided. New records for some countries of the Mediterranean basin and Macaronesia are given. Five new Synonyms are proposed. The designations of 11 new lectotypes are included and the name Syntrichia aciphylla var. calva J.J. Amann is excluded from the genus Syntrichia.
The Japanese micropterigid moths are revised. Seventeen species in five genera are recognized from Japan, described or redescribed with the male and female genital figures. Of these, two genera, Issikiomartyria HASHIMOTO and Kurolkopteryx HASHIMOTO, and seven species, Issikiomartyria akemiae HASHIMOTO, Issikiomartylia plicata HASHIMOTO, Issihiomartyria distincta HASHIMOTO, Issihiomartyria bisegmentata HASHIMOTO, Kurokopteryx dolichocerata HASHIMOTO, Neomicropteryx hiwana HASHIMOTO, and Neomicropteryx redacta HASHIMOTO, are new to science. A new combination is given: Issikiomartyria nudata (Issuu). Biology and immature structures of the Japanese species are also described together with the keys to genera and to species provided on the basis of the adult characters. Phylogenetic relationships among the Northern Hemisphere genera are analyzed by the cladistic analysis using PAUP* (SWOFFORD, 2002) based on the morphological characters of adults. A monophyly of the Northern Hemisphere genera except for Micropterix is supported by nine apomorphies, but their immediate sister taxon remains unresolved.
Westwoodilla Bate. 1862 is revised and 12 species are recognized as distinct, 2 of which, W. tone and W. helle. are described as new. New characters of taxonomic importance are described and illustrated. The many variable characters that have led to taxonomic confusion in the pas! are converted to morphometries and the intra- and interspecific variation are illustrated. This has led to a new understanding of the genus and a clarification of the "W. caecula complex". The type species Westwoodia caecula Bate. 1857 is redescribed and a neotype is designated. W. megalops (Sars, 1883) is resurrected. The junior synonymy of W. longidactyla Carausu, 1949 with W. caecula is supported by the find of Carausu's original unpublished notes and drawings. Notes on undescribed species are given. New drawings are provided for W. manta Griffiths, 1974, W. longimana Shoemaker, 1934, W. brevicalcar (Goes, 1865) and W. megalops. All species are diagnosed; new distributions are given and plotted on a map; and a key to the named species is included.
In the present revision of Sabia the number of species has been reduced from 55 to 19, including two that are described as new. Below the specific level, a new subspecies and a new variety are described, whereas some new infra specific combinations have been made. Most of the reduced species have been included in the synonymy of S. campanulata, which consequently represents the most complex and most variable species of the genus. Next to a general key, some regional keys are given as on the one hand some widespread species are locally far less variable than taken over their whole area, on the other hand well-delimited species from different regions may be very uniform in some points.
A recently completed field survey of springs throughout the Great Basin yielded collections of hydrobiid snails from more than 500 sites, and revealed a wealth of undescribed diversity of these small gastropods. In this, the first or a two-part taxonomic series treating this material, 58 new species of Pyrgulopsis Call & Pilsbry, 1886, are described; and new records are provided for 10 previously described members of this genus. Assignment of these novelties to Pyrgulopsis is done with the acknowledgement that this large genus, as currently constituted, is probably not monophyletic, but a more refined classiffcation of these snails reflecting evolutionary relationships must await preparation of a phylogenetic analysis, which is beyond the scope of this work. Pyrgulopsis occur in a variety of spring-fed water bodies in the Great Basin, including brackish and/or thermal habitats. Although a few species are widespread in the region, local endemism is prevalent lind 22 of the new species are known only from single localities. Several areas contain concentrations of locally endemic snails which may represent species flocks, notably Duckwater Valley (seven species) and southern Steptoe Valley (five species). This fauna is hugely distributed in an allopatric fashion, although a few springs harbor two or three species. Most of the springs inhabited by hydlrobiids in the region are small, fishless, and have been ignored by state and federal land management agencies. However, many of these sites are degraded by livestock grazing, water withdrawal, anti other activities and will require protection in order to conserve snails and other native aquatic biota. Two of the novellies described herein have become extinct during the past two decades.
This second and final part of a taxonomic treatment of hydrobiid snails of the Great Basin region in the western United States (based principally on material collected during a recently completed field survey) focuses on fauna other than the genus Pyrgulopsis. A new genus of small amnieoline snails, Colligyrlls, is proposed for Hydroia greggi Pilsbry, 1935, together with a new species from the Harney Lake basin of Oregon. This group is strongly differentiated from other amnicolines by a unique female genitalic groundplan. New records are provided for three species of Fluminicola, and two new congeners are described from the northwest Great Basin, both of which had previously been confused with F. turbiniformis (Tryon, 1865). A new genus of cochliopine snails, Eremopyrgus, is erected for a new species from Steptoe Valley, Nevada. Eremopyrgus is distinguished from other cochliopines by unique aspects of its glandular penial lobes and other genitalic features. New records are provided for two species of Tyronia, and a new congener is described from thermal springs in central Nevada. Several new records of Pristincola hemphilli (Pilsbry, 1890) from the extreme northwest Great Basin are provided
A skeletal world revision of the genus is presented to accompany a family account for Flora Malesiana. 82 species are recognised, of which 74 occur in the Malesiana region. Six species are desctibed as new, one species is raised from infraspecific status, and five species are restored from synonymy. Many names are typified for the first time. Three widespread, or locally abundant hybrids are also included. Full descriptions are given for new (6) or recircumscribed (7) species, and emended descriptions of species arc given where necessary (9). Critical notes are given for all the species. Little known and excluded species are discussed. An index to all published species names and an index of exsiccatae is given.
Until recently, up to thirteen specics of the scincid genus, Scincus, were recognized, but examination of some 590 individuals frorn a wide range of localities suggests that only three or four are valid. Of these, S. mitranus is confined to eastern and southern Arabia and S. hemprichii probably to southwest Arabia. The remaining forms constitute the S. scincus complex, which may consist in North Africa of two largely allopatric species, S. scincus and S. albifasciatus, although evidence for this is not conclusive. The S. scincus complex is represented in southwest Asia by two forms : S. scincus meccensis in southern Jordan, northwest and west Arabia and S. s. conirostris in southern and eastern Arabia, Iraq and southwest Iran. Scincus appears to have evolved Erom a primitive scincine, very similar to members of the Eumeces schneideri group, especially E. (schneideri) algariensis; it does not seem to be directly related to the sympatric genus Scincopus. Within Scincus, the S. scincus complex is the least specialized component of the genus and both S. rnitranus and S. hemprechii may have been independently derived from it, or from a closely related form. Possibly the whole range of the genus was once occupied by a S. scincus-like species and its distribution was subsequently restricted by the onset of less desertic conditions leaving reduced populations in North Africa, southwest Arabia and southeast Arabia that gave rise to the S. scincus complex, S. hemprichii and S. mitranus respectively. A renewed expansion of arid areas could then have enabled the S. scincus complex to invade southwest Asia. Some of the characters of its most eastern subspecies, S. s. conirostris, may have arisen, or been maintained, by character displacement through contact with S. mitranus.
Several generic schemes used in classifying species belonging to Prionospio Malmgren, 1867 sensu lato have been reviewed; three taxa have been retained at the generic level, and three additional taxa at the subgeneric level. The following genera and subgenera are recognized: Prionospio Malmgren, 1867, including the subgenera Minuspio Foster, 1971, Aquilaspio Foster, 1971 and Prionospio Malmgren (sensu striclo); Apoprionospio Foster, 1969, and Paraprionospio Caullery, 1914. Prionospio sensu lata includes species with various combinations of branchiae which are smooth (apinnate), wrinkled, or with digitiform pinnules, beginning on setiger 2. Apoprionospio includes species having branchiae from setiger 2, with at least one pair having plate-like pinnules. Paraprionospio includes species with branchiae from setiger 1, with all pairs having platelike pinnules. Fifteen species, including seven new species, belonging to the genus Prionospio are described. Prionospio (Prionospio) steenstrupi Malmgren, 1867 is described from the syntype series, and is newly synonymized with P. fallax Söderström, 1920. The validity of P. bocki Söderström, 1920 as a separate species is discussed, as is the indeterminable nature of P. malmgreni Claparède, 1869. Prionospio (Prionospio) dubia Day, 1961 originally described as a new variety of P. malmgreni from S Africa, is raised to full species status. Prionospio (P.) cristata Foster, 1971 and P. (P.) heterobranchia Moore, 1907 are redescribed. Prionospio (P.) tripinnata, a new species with three pairs of pinnate branchiae, is described from the Mediterranean Sea and compared with P. plumosa Sars, 1872. A new synonymy is proposed for P. lobulata Fauchald, 1972 with P. (P.) ehlersi Fauvel, 1928. Two new species, P. (Minuspio) fauchaldi and P. (M.) laciniosa, are described in which the apinnate branchiae are distinctly wrinkled or sculptured, rather than smooth. P. (M.) laciniosa is also distinguished by dorsal crests modified into semicircular flaps. Several species previously referred to Prionospio (Minuspio) cirrifera Wirén, 1883 are reviewed and described. The seven species recognized by Foster in the genus Minuspio are considered; several are retained, and new species and new synonymies are proposed. Because the types are apparently lost, a description of P. (M.) cirrifera is given based on specimens from near the type locality. Prionospio (M.) aluta new species is separated from P. (M.) cirrifera on the basis of the presence of lateral pouches in P. aluta and their absence in P. cirrifera. Prionospio (M.) delta Hartman, 1965 is retained as a valid species; P. (M.) longibranchiata Reish, 1968 and P. (M.) minor Fauchald & Hancock, 1981 are newly synonymized with P. delta. P. (M.) multibranchiata Berkeley, 1927 is also retained as a valid species, and P. (M.) perkinsi, P. (M.) lighti and P. (M.) wireni are newly described from shallow water. Two species are recognized as belonging to Apoprionospio Foster: A. pygmaea (Hartman, 1961) and A. dayi Foster, 1969. New records and range extensions are given for both species. New records are also presented for Paraprionospio pinnata (Ehlers, 1901). The specimens examined as part of this study are based primarily on deep-sea materials collected in the Atlantic Ocean, but also include shallow-water specimens from the east, west, and gulf coasts of N America.
This paper is a monographic revision of tlie Holarctic genus Hilarimorpha Schiner. Twenty-seven species are recognized, twenty-two of which are new: Hilarimorpha abuta, bumulla, californica, clavata, cunata, desta, kena, lamara, Iantha, loisae, mandana, mentata, modesta, parva, pitans, punata, reparta, robertsoni, sidora, stena, tampa, and varda. Two described species from Asia, Hilarimorpha maculata and orientalis, are removed from the genus. In addition to a taxonomic revision of the genus, this study treats geographical distribution of the species, and the relationship of the genus to othe families of brachycerous Diptera.
The ant genera Ankylomyrrna Bolton, Atopomyrmex Andre, Cyphoidris Weber, Ocymyrmex Emery, Pristomyrmex Mayr (= Odontomyrmex Andre, = Hylidris Weber, = Dodous Donisthorpe) and Terataner Emery (= Tranetera Arnold) are revised for the Ethiopian zoogeographical region. Keys and descriptions of species are presented for each genus and the genera are defined on a world-wide basis. In Atopomyrmex two species are recognized and four new infraspecific synonyms are established. Three new species are described in the previously monotypic genus Cyphoidris. Twenty-three species of Ocymyrmex are recognized of which seven are described as new; seven new synonyms are established and new Status as valid species is granted to seven previously infraspecific forms. Five Pristomyrmex species are recognized of which one is new; five new Synonyms are proposed in this genus. In Terataner the former subgenus Tranetera is newly synonymized and six species recognized, of which one is new. The six Terataner species of Madagascar are summarized, one new species is described and a key presented. The genus Baracidris is described as new, containing two new species from West and central Africa. A key to Ethiopian region myrmicine genera in which the antennal club has two Segments is given under Baracidris.
In this paper all the Japanese species of the family Lejeuneaceae were critically reviewed. As the result four subfamilies, twenty-one genera, and seventy-eight species were recognized under the family. Discussions were made on the relationship of the genera within the family and with other families (Tables 1-4). The new subfamily Jubuloideae was established (the type is Jubula), and the genera, Hattoria and Nipponolejeunea, were included in it. More than thirty species were reduced to synonymy under others, and eighteen new combinations were made. The seven types of distribution were recognized, according to the distribution patterns of species in Japan (Map 1, Table 5).
In order to elucidate what species among so many kind of marine organisms are likely to be consmed Iargely by the balaenopterid whales, the existing evidence on the food habits of baleen whales is reviewed. To meet with this primary purpose the report was mainly focussed on to describe qualitative aspects of food species having been known to date from the notable whaling grounds over the world rather than documenting quantitative subjects. One of interesting facts noticed throughout the contribution was that there exists fairly intense diversity in the assembly of food species composition by regions such as; northern hemisphere vs. southern hemisphere, Pacific region vs. Atlantic region, inshore waters vs. offshore waters, embayed waters vs. open waters, where the former usually shows more diversed complexity than the latter. The fact however suggests that although the composition of food species locally varies over the various whaling grounds, the food organisms as taxonomical groups are very similar one another even in locally isolated whaIing grounds when the food organisms and their assemblies are considered by the family or genus basis. In this connection many evidences given in the text may suggest that the balaenopterid whales as a whole may substantially live on quite simply compositioned forage assembly in comparison with tremendous variety of organisms existing in the marine ecosystems. One of important aspects of the baleen whales food must be found in their characteristics of forming dense swarms, schools, and/or aggregations in the shallower enough layers to be fed by the whales. The present and past status of larger baleen whales as the mighty monarch through their evolutional pathways may entirely depend upon the spatial distribution pattern of possible food organisms, i.e. the animal aggregations.
The 70 Frullania species (+ 1 subspecies, 9 varieties, and 3 formae) belonging to 9 subgenera are confirmed in China, among which 1 subgenus and 4 species are new to science, and 12 species are newly reported from China. A new name (nom. nov.) and 12 combinations are proposed and several species are reduced to synonyms of other species. This study reveals the Frullania flora of China, particularly Yunnan and the neighboring provinces, to be most highly differentiated, containing many phytogeographic ally interesting taxa, and may be regarded as a center of the Paleotropic Frullania flora.
Keys to the hairs of 44 species of southern African Cricetidae and Muridae have been devised for the identification of these species. The keys are based primarily on the cuticular scale patterns and groove characters. Distribution data and descriptions of the hairs are presented with micrographs to assist in identification.
Interaction between species in a marine ecosy stem is described by expressions for food consumption and grazing mortality which are consistent with each other and with the Beverlon and Holt model of the population dynamics ofindividual species. A model of primary production is introduced in order to make possible an account of nutricnt circlliation (as examplified by phosphorus) within and nutrient flow through the system. It is demonstrated in an application to North Sea fishencs that recent changes in total yield can be described in some detail under the terms of the model as a function of fishing mortality alone. The composition of the North Sea fauna in the virgin state is discussed and also the conditions under which total yield could be increased above the 1970 level.
1. In investigating a spontaneous epidemic disease of rabbits, a micro-organism was isolated in pure cultures which reproduced the characteristic lesions of the natural disease.
2. The bacteriological characters of this bacillus are described and the impossibility of identifying it with previously recorded organisms justifies its being considered a new species. The name Bacterium monocytogenes is proposed.
3. Animal passage raised "virulence" when the doses were well chosen, and increased virulence accentuated the production of necrotic lesions. Overwhelming doses of culture resulted in lowering of "virulence" by animal passage.
4. Bacterium monocytogenes, in doses less than the M.L.D., produced in the circulating blood of rabbits an extreme monocytosis. The responses of the other white cells. were either transient or inconstant.
5. Repeated doses of the organism became progressively less effective as stimuli to large mononuclear production.
6. The cell content of the thoracic duct did not reflect the high degree of monocytosis in the circulating blood.
7. On intrapleural injection of peptone broth and B. coli, the cells of the resultant exudate were primarily polymorphonuclears, even though the circulating blood showed a high monocytosis. With intrapleural injection of B. monocytogenes, when the blood stream was rich in large mononuclears, a pleural exudate containing 30 per cent of these cells was obtained.
8. Phagocytosis experiments in vitro showed that the large mononuclears, while they phagocyted B. coli indifferently, took up B. monocytogenes with an avidity in all respects equal to that of the polymorphonuclear neutrophiles.
The North Arnerican species of the genus Cremastocheilus are reviewed. These belong to 5 subgenera, Macropodina, Trinodea, Anatinodia, Mymcotonus, and Cremastocheilus. Taxonomie changes are: She inclusion of Crernastocheilus nitens and C. chapini in the subgenus Cremastocheilus rather than Myrmecotonus. Also Anatinodia is elevated to subgeneric status. A key to the subgenera is provided, as is a key to the species of the 5 subgenera, recognizing that the 35 species in the subgenus Cremastocheilus are in need of revision. A critical review of the host records, geographic distribution, and ecology of the Tribe Crernastocheilini (Family Scarabaeidae. subfamily Cetoniinae) is provided. This contains enormous numbers of new records for both the genera Genuchinus and CremastocheiLus both from the literature and from the extensive field work that is reported here for the first time. A Summary of the host records is presented in tabular form. This table shows the association of all species of Cremastocheilus with ants as adults and the larvae either associated with the vegetable material of the ant nests or with vegetable material in rodent burrows. Genuchinus is shown to be a general predator on soft bodied insects while the other genera of the Cremastocheilini are associated with plants, particularly bromeliads. A detailed study of the external morphology and sexual dimorphism of the genera Genuchinus and Crernastocheilus is presented. All species of Cremastocheilus can be sexed with the naked eye by the difference in the shapes of the abdominal terminal Segments, wherein males have the posterior border of the last ventral abdominal segment either straight or slightly bowed, while females have this border broadly rounded. There are other microscopic sexual differences in the structure of the legs. The rest of the external morphology is also presented, particularly from the point of view of adaptations to either a predaceous or rnyrmecophilous existente. Particularly adapted for predation are the pointed maxillae which are used for piercing prey. Particularly adapted for myrmecophily are the mentum, the maxillae, the generally thick exoskeleton, trichomes on both the anterior and posterior angles of the pronotum, the elytra, and the legs (which are adapted to the nest substrate of the host ant nests. Exocrine glands are described for Genuchinus ineptus and at least 1 species of each of the 5 subgenera of Cremastocheilus. In general, there are no gland cells nor glandular areas in Genuchinuc that are comparable to those of Cremastocheilus. The gland cells and glandular areas are quite extensive andvariable arnong species of Cremastocheilus. The frontal gland of some Cremastocheilus (strongly developed in C. castaneus and the C. canaliculatus species group, but weakly developed in the C. wheeleri species group) is described for the first time. Because these glands are not found in Genuchinus ineptuc, a species with general predatory habits, it is thought that these play a role, as yet unknown, in interactions with ants. The life cycles of the subgenera of Cremastocheilus are described. The general life cycle entails adult beetles eclosing in ant nests during the summer and then undertaking dispersal flights. The adults then enter ant nests and ovenivinter there, eating ant larvae during the Winter. Another dispersal flight occurs in the spring during which the adults mate and enter ant nests again. The females then lay eggs and the adults die. The eggs hatch and the larvae spend 3 instars feeding upon vegetable material in the nests. The lmae then pupate in typical scarabaeine earthen cells made of fecal material and soil. These eclose in the summer and the cycle is repeated. Variation from species to species is largely in the timing. Leaving the nest in late Summer, mating seems to be triggered by rainfall in all the species studied. Mating of C. (Macropodina) beameri takes place in rodent burrows. Males seem attracted to females from a distance but the mechanism of this remains obscure. In the subgenus Trinodia, mating takes place on sandy washes or roadsides where females land. In the subgenus Myrmecotonus, maüng also takes place in sandy areas. In C. (Cremastocheilus) mating takes place on sand bars along rivers in the southeastern U.S. and in sand dunes in northeastern U.S. The femaies dig down into the sand. Males locate these places by some unknown mechanism and then dig down to copulate with the females. Field experiments showed unequivocaily that males dig only into areas occupied by females. No sex-specific Sex attractant glands have been located in females so far. Dispersal to ant nests occurs after mating except for C. (Macropodina) beameri which lays its eggs in the rodent burrows and then probably disperses to ant nests. Beetle activity going in and out of nests was studied using wire hardware cloth screens over entrances to Mynnecocystus nests. The mesh size was such that the ants could move freely in or out but the beetles got stuck by their thoraces. The direction then could be interpreted by the direction in which they got stuck. By this method, C. stathamae was shown to leave nests from 23 June to 1 September with a peak on 6 July, just after the beginning of the summer rains. Beetles entered nests from June 23 to August 3, however 39% entered on July 16, probably pulsed by the leaving time which was correlated with the rains. Life cycle timing: C. (Macropodina) develop in the nests of Wood rats (Neotoma sp.]. Females lay about 40 eggs each. The 3 larval instars to pupation take about 1 month. Pupae are found from late August to weil into September. In other subgenera as well, larvae are found in parts of the nest devoid of ants, The timing is similar in all the subgenera found with ants. Mortality factors: While ants attack Cremastocheilus adults, there is no evidence that they are ever killed by ants nor is there evidence that ants kill larvae nor hard earthen pupae cases which protect the pupae. During dispersal fiights and mating, the adults are exposed to predation and evidence is presented that shows predation by horned toads, spiders, magpies, and tiger beetles. Probably most mortality occurs in the larval and pupd stages where the beetles are attacked by internal parasites and fungus. Further rnortality is caused by limitation of the food supply during the larval stage. Reentering nests: Females of C. (Macropodina) beameri select specific rodent and other burrows, attract males for rnating. and then enter the burrow for oviposition. C. stathamae are carried into the ants nests from as far away as 25ft. The beetles appear to land spontaneously after flying randomly over M. depilis nesting areas. Then the wander about waiting for the ants to carry them into the nests. Cremastocheilus hirsutus fly low over the ground searching for Pogonomyrrnex barbatus nests, land. and move straight for the nest entrances which they enter unhindered. Among all species, the ants frequently eject beetles but the net rnovement is in. Ants frequently attacked Cremastocheilus in laboratory observation nests when they were introduced. These attacks seldom resulted in the death of the beetles and the beetles were eventually ignored. When the beetles entered brood chambers, where they fed upon larvae, they were mostly ignored and even licked assiduously by the ants. A principle defensive behavior by the beetles is feigning death (letisimulation). The beetles give off an unpleasant "dead fish odor when collected in the I field. Experiments show that this substance functions to fend off some predators but further experiments indicated that these substances were ineffective against both ants and kangaroo rats. Experiments with various species of Cremastocheilus adults indicate that the adults eat only ant larvae. The beetles will eat larvae of non-host ants but show preferences for the larvae of their normal hosts. Under the same experimental conditions. Genuchinus ineptus adults will feed on a variety of insect adults and larvae. Field experiments on the function of trichome secretions did not indicate that they function to attract ants at a distance nor are they involved in worker acceptance. Laboratory experiments in which areas with a high concentration of gland cells were presented to ants showed that no ants were attracted. Laboratory introduction of Cremastocheilus hamisii adults into Fomica schau.si nests yielded many interactions including ants licking the anterior pronotal angles, the mentum area where the frontal glands empty and a carina over the eye with a dense pad of short setae. These are areas of concentration of gland cells and these are the first observations of licking by ants in specific sites containing exocrine glands. Radioisotope experiments showed food exchange among ants but never from ants to beetles. Other experiments showed that ants can pick up radioactivity from the beetles without feeding on trichome secretions. Evolutionary pathways: Adult Cremastocheilini probably followed the evolutionary route from adult predation on soft bodied insects to specialized feeding upon ant brood and the subsequent development of the beetle larvae in vegetable material in the ant colonies. Thus Genuchininseptus makes a logical outgroup in that they are general predators probably feeding mostly on Diptera larvae associated with Sotol plants in the field. The rnajor evolutionary step taken by Cremastocheiluswas to specialize on ant brood. Then the species radiated into ant colonies inhabiting southwestem North Arnenca. Most of the ant hosts invaded have quantities of vegetable material in their nests sufficient to support several developing scarab larvae. Host colonies are large, contain accessible brood, and are usually dominant foragers Evidence supports the idea that the species of Cremastocheilus have differentes in behavior and morphology that reflect adaptation to the behavioral ecology of different species of ants rather than different evolutionary levels of integration into ant colonies.
The morphology of the skeletal portions of the sting apparatus is described and compared in 63 genera of myrmicine ants in order to evaluate its taxonomic potential in this difficult subfamily. The survey covers about half of the myrmicine genera, and an but 3 small tribes (Ochetomyrmecini, Melissotarsini, Stegomyrmicini). Interspecific variation in the apparatus is described in a third of the genera examined. In addition, the sting apparatus of the primitive ponerine ant, Amblyopone pallipes is described for comparison with the primitive myrmicines; and the sting associated glands (poison gland, Dufour's gland) are illustrated for single species of Amblyopone, Basiceros, Monomorium, Aphaenogaster, Crematogasier, and Zacryptocerus.
As a preliminary step towards a more intensive research on the diversity of macromycetes in Greece, an updated check-list of the Greek mycoflora is presented together with information on the host-substrates and geographic occurrence. The data originated from a thorough literature search and the authors' field observations. In total, 58 families, 214 genera and 811 species of fungi are recorded belonging to Basidiomycetes. The systematics and nomenclature of the relative bibliography have been updated and suitably revised. The large gaps in our knowledge on the existence and distribution of higher fungi in Greece are emphasized.
