We studied the composition and abundance of benthic mollusks found in La Guajira along the northern Caribbean coast of Colombia. A research cruise was carried out on board the R/V Ancón INVEMAR, from which bottom trawlings were conducted at 10 and 50 m depths. A total of 4840 individuals were collected, and 215 species identified belonging to the classes Gastropoda, Bivalvia, Scaphopoda, Cephalopoda and Polyplacophora. Nineteen species were recorded for the first time in La Guajira. The class Gastropoda had the highest number of species (52 %) and Bivalvia showed the greatest abundance (71 % of individuals). The bivalve Laevicardium sybariticum was the most abundant species in the study area. Multivariate analysis showed no defined patterns in relation to depth and bottom type.

Riassunto - Gli scopi di questa ricerca sono quelli di contribuire alla conoscenza della macrolepidotterofauna della Sicilia nord-orientale e di caratterizzare la comunità presente nella Riserva Naturale Orientata “Laghetti di Marinello”. Sono stati effettuati 23 campionamenti tra dicembre 2007 e dicembre 2008 col metodo della caccia al lume. Sono stati catturati 2.537 individui appartenenti a 160 specie, tra cui Chloroclystis v-ata e Laelia coenosa, segnalate per la prima volta in Sicilia; importanti anche le segnalazioni di Calamodes subscudularia, Mythimna languida e M. joannisi, specie piuttosto rare e localizzate. Le specie più abbondanti sono state: Eilema caniola, Eublemma viridula, Idaea filicata, Dysauxes famula e Idaea seriata, che da sole rappresentano il 42% di tutta la comunità, favorite dalla presenza delle rispettive piante nutrici e dall’elevato adattamento alle condizioni climatiche del sito. Il numero di specie e i valori degli indici di diversità indicano un basso livello di biodiversità ospitata, ma la fenologia, le analisi corologica e autoecologica delle specie, insieme ai confronti effettuati con altre faune, indicano una comunità ben caratterizzata e peculiare, diretta espressione delle condizioni abiotiche e biotiche della Riserva.Abstract - Macroheterocera of the Oriented Natural Reserve “Laghetti di Marinello” (north-eastern Sicily) (Lepidoptera: Heterocera). The aim of this research is to contribute to the knowledge of the fauna of macrolepidoptera of north-eastern Sicily and to describe the community present in the Oriented Natural Reserve “Laghetti di Marinello”. 23 samples were carried out from December 2007 to December 2008 using a white vertical sheet reflecting a light source. 2.537 specimens belonging to 160 species were captured. Chloroclystis v-ata and Laelia coenosa were reported for the first time in Sicily, Calamodes subscudularia, Mythimna languida and M. joannisi, very rare and localized species, were also reported. The most abundant species were: Eilema caniola, Eublemma viridula, Idaea filicata, Dysauxes famula and Idaea seriata, which represent the 42% of the whole community and are favoured by the presence of their feeding plants and by their high adaptability to the climatic conditions of the place. The number of species and the values of the diversity indices show a low level of biodiversity, but phenology, chorological and autoecological analysis of the species, with comparisons made with other faunae, show a well characterized and peculiar community, direct expression of the abiotic and biotic conditions of the Reserve.

AbstractIn 2001–2007, altogether 57 nests of lesser spotted eagle were collected in the Orava region in northwestern Slovakia and four groups of arthropods were extracted from them. Richest in number of species and individuals were mites (23 species, 17,500 ind.), followed by beetles (12 species, 725 ind.), whereas pseudoscorpions were represented only by Pselaphochernes scorpioides (39 ind.) and fleas by Ceratophyllus garei (3 ind.). Unlike nests of other birds, free-living mites predominated in the nests fauna (83% of individuals), followed by nidicolous species with more or less free relationship to the nests, while parasitic species represented only a negligible part of the fauna. For the first time we observed phoresy of Nenteria pandioni, a specific and abundant mite in the eagles’ nests, on the nidicolous staphylinid Haploglossa puncticollis. The beetle fauna in the nests was much poorer than in nests of other birds. The predatory H. puncticollis was dominant in the nests (83%) and occurred continuously during the whole investigation period. Other beetles, even the widely distributed nidicols such as the histerid Gnathoncus buyssoni, were found rarely in nests. Predators were also the only abundant trophic group of beetles in the nests, while other trophic groups of beetles abundantly co-occur in nests of majority of other birds. The occurrence of all beetles was very unevenly distributed during the investigation period, but was positively correlated with occurrence of mites. The relatively low number of species and individuals of mites and beetles in the lesser spotted eagle nests resulted from their position on tree tops, at a height of 20–30 m and their quick drying out by sun and wind. It was also indicated by an enormously low number of species and individuals of mycetophagous beetles, which represent a significant component of the fauna in nests of other birds.

Coleoptera of the family Geotrupidae play an important ecological role in the decomposition of animal and plant organic matter. In Brazil there is little information on the diversity and distribution of this group, thus, this work had a purpose to study Geotrupidae species, occurring in Aquidauana, MS. A survey for geotrupids was conducted in Aquidauana, Mato Grosso do Sul, Brazil. Beetles were captured using a light trap over a period of two years, from January 2006 to December 2007. A total of 907 specimens were collected and identified to eight species. From the subfamily Bolboceratinae, the species identified were Bolbapium minutum (Luederwaldt, 1929) and Pereirabolbus castaneus (Klug, 1845). In the subfamily Athyreinae the species identified were Athyreus bilobus Howden & Martínez, 1978, Parathyreus aff. bahiae, Neoathyreus aff. julietae, N. sexdentatus Laporte, 1840, N. centromaculatus (Felsche, 1909) and N. goyasensis (Boucomont, 1902). Four species (A. bilobus, N. centromaculatus, N. goyasensis and P. castaneus) are reported for the first time in Aquidauana, MS, Brazil. The most abundant species, representing 85.9% of the total capture, was B. minutum. The greatest numbers of specimens was caught from October to December of both years of the study.

AbstractThe amphibian fauna of Sichuan Province, China, is remarkable for the large number of species of pelobatid frogs, of which species of Oreolalax form a large portion. We have collected larvae of five species of Oreolalax on Mt. Emei, Sichuan, four of these five at a second locality 40 km from Mt. Emei, and larvae of two additional species at a locality 200 km S of Mt. Emei. These tadpoles are very similar to one another morphologically, a conclusion supported by multivariate analysis. We give diagnostic descriptions and a key for the identification of these seven larval forms. All tadpoles of Oreolalax have lotic habits, and the seven species in our study live in small to medium-sized streams (maximum width 8 m). These species show only moderate ecological segregation in terms of stream size and microhabitat type.

There are only a few published bat surveys from the southwestern Brazilian Amazon, but recent studies have reported additional bats species in the region. We provide the first list of bat species from Floresta Estadual do Antimary (Antimary State Forest) and record for the first time Glyphonycteris sylvestris Thomas, 1896 and Phylloderma stenops Peters, 1865 in the state of Acre, increasing to 64 the number of species known from this state. Our survey enlarges the known geographic range of G. sylvestris in Brazilian territory and improves the inventory of bat species in a poorly sampled region of the Amazon.

Located in southwestern Maranh&atilde;o, the Parque Nacional da Chapada das Mesas (PNCM), with an extent of about 160,046 ha, is completely inserted in the Cerrado phytogeographic domain. The topography is characterized by a plateau formation consisting of steep hills and medium-altitude mountains with flat tops, which give the PNCM its name. We present an annotated checklist of the mosses that occur in the PNCM. Our checklist includes 26 species of pleurocarpous mosses distributed in 10 families and 22 genera and two species of cladocarpous mosses of the family Orthotrichaceae. The most species-rich families of pleurocarpous mosses were Sematophyllaceae (7 spp.), Pylaisiadelphaceae (6 spp.), and Stereophyllaceae (4 spp.). Eleven species are recorded for the first time from Maranh&atilde;o and three species are recorded for the first time in the northeast region of Brazil. Taxithelium pluripunctatum (Renauld &amp; Cardot) W.R. Buck and Trichosteleum glaziovii (Hampe) W.R. Buck, are recorded for the first time from Maranh&atilde;o and the Cerrado phytogeographic domain. Our results expand the knowledge of the Brazilian bryoflora and add distribution data for a number of species in Maranh&atilde;o and the northeast region.

As a result of mycological research 34 species of coprophilous ascomycetes from 14 genera, 10 families, and 5 orders were recorded on the territory of the Oleshkivski Pisky National Nature Park. Among them 15 species belonged to the class Sordariomycetes, 12 – to Dothideomycetes, and 7 – to Pezizomycetes. Among the orders of the fungi, Sordariales – 12 species, Pleosporales – 11, and Pezizales – 7, occupy the leading position; the rest of the orders revealed the fewer number of species. Among the families, Sporormiaceae, Podosporaceae, Coniochaetaceae, Delitschiaceae, and Sordariacea, were the most abundant regarding the number of species and specimens. The species from the five leading families represent 64,7% of the total number of identified species. Among the found genera of the coprophilous ascomycetes, Coniochaeta, Delitschia, Sordaria, Sporormiella, and Triangularia prevailed by number of species, demonstrating much larger diversity, than others. Environmental conditions inside the park are more favorable for the development of loculoascomycetes and pyrenomycetes. The discomycetes species diversity was much less. The list of recorded fungi and their substrates is presented. All species of ascomycetes were collected on the hare and cattle excrements. Other dung types have not been studied. 31 species are new to the territory of the park, 15 species are new records for the steppe zone of Ukraine. Coniochaeta hansenii and Sporormiella tetramera are first recorded in Ukraine. Descriptions, illustrations, synonyms and general distribution are provided for them. C. hansenii is a fairly common and widespread species in the world, occurring mainly on the leporid droppings. In the park, this species was also collected on hare dung. S. tetramera also belongs to the widespread but rare species of coprophilous ascomycetes, known from isolated records in a few countries. It was collected on the hare excrements in the park. Сoniochaeta leucoplaca, Delitshia perpusilla and Triangularia comata were collected for the first time in the steppe zone of Ukraine and for the second time in the country. У результаті дослідження копрофільних аскоміцетів Національного природного парку «Олешківські піски» було виявлено 34 види грибів із 14 родів, 10 родини та 5 порядків. Це представники трьох класів: Sordariomycetes – 15 видів, Dothideomycetes – 12, Pezizomycetes – 7. Серед порядків найчисельнішими є Sordariales – 12 видів, Pleosporales – 11 та Pezizales – 7. У родинному спектрі грибів переважають представники Sporormiaceae, Podosporaceae, Coniochaetaceae, Delitschiaceae та Sordariacea, які об’єднують 64,7% загальної кількості виявлених видів аскоміцетів. Серед родів переважають Coniochaeta, Delitschia, Sordaria, Sporormiella та Triangularia. Екологічні умови території парку є більш сприятливими для розвитку локулоаскоміцетів і піреноміцетів. Кількість знахідок видів дискоміцетів є незначною. Представлено список зареєстрованих видів грибів, для кожного виду вказано локалітети та живильні субстрати. Всі види грибів зібрані на посліді зайця та корови. Інші типи копром не досліджувались. З виявлених видів аскоміцетів 31 наводиться вперше для території парку, 15 є новими для степової зони України. Два види аскоміцетів є новими для мікобіоти України та Східної Європи: Coniochaeta hansenii та Sporormiella tetramera. У статті представлено їх діагнози та фото, обговорюються деталі морфології, субстратної приуроченості та поширення у світі. C. hansenii є досить звичайним та поширеним у світі видом, що переважно трапляється на екскрементах зайцеподібних.На території парку також була зібрана на копромах зайця. S. tetramera належить до поширених у світі, але рідкісних видів копрофільних аскоміцетів, відомих з поодиноких знахідок у небагатьох країнах. У парку зібрана на посліді зайця. Знахідки Сoniochaeta leucoplaca, Delitshia perpusilla та Triangularia comata є новими для території степової зони України та вдруге наводяться для нашої держави.
