Longstanding observations suggest that dissolved materials are lost from fresh litter through leaching, but the role of soil fauna in controlling this process has been poorly documented. In this study, a litterbag experiment employing litterbags with different mesh sizes (3 mm to permit soil fauna access and 0.04 mm to exclude fauna access) was conducted in three habitats (arid valley, ecotone ...
background: the aim of this study was to determine intestinal and liver helminth infections in rattus rodents in tehran iran. methods: overall, 306 traps were put in 39 different regions in tehran from 2009 to 2010. rodents, including r. rattus and r. norvegicus were caught by live-traps.they become unconscious and the spinal cords were cut, afterwards the body was dissected and the stomach, sm...
Fauna Europaea is Europe's main zoological taxonomic index, making the scientific names and distributions of all living, currently known, multicellular, European land and freshwater animals species integrally available in one authoritative database. Fauna Europaea covers about 260,000 taxon names, including 145,000 accepted (sub)species, assembled by a large network of (>400) leading specialist...
Moth species were studied from some selected districts of Assam (i.e., Cachar and Barpeta district) to determine their diversity index, species richness and evenness of Arctiidae and Geometriidae family of the moth fauna.The moths were collected by applying specialized trapping methods using UV light operating during night. Collected moth species were identified up to family-genusspecies level....
This paper presents an updated checklist of the Greek scale insect fauna and the results of the first zoogeographic analysis of the Greek scale insect fauna. According to the latest data, the scale insect fauna of the whole Greek territory includes 207 species; of which 187 species are recorded from mainland Greece and the minor islands, whereas only 87 species are known from Crete. The most ri...
Future studies, however, will make progress by running across study sites and geographic regions to test functional hypotheses of baboon social evolution. As a case in point, one of the most prominent behavioural differences between baboon allotaxa lies in the occurrence of coalitionary behaviour among unrelated, reproductively competing males: this is a problem of real substance, because this ...
The subterranean environment of Christmas Island is diverse and includes freshwater, marine, anchialine, and terrestrial habitats. The cave fauna comprises swiftlets, and a diverse assemblage of invertebrates, both terrestrial and aquatic, which includes a number of rare and endemic species of high conservation significance. At least twelve species are probably restricted to subterranean habita...
The Arctic Mid-Ocean Ridge (AMOR) represents one of the most slow-spreading ridge systems on Earth. Previous attempts to locate hydrothermal vent fields and unravel the nature of venting, as well as the provenance of vent fauna at this northern and insular termination of the global ridge system, have been unsuccessful. Here, we report the first discovery of a black smoker vent field at the AMOR...
Soil fauna are critical for ecosystem function and sensitive to the changes of soil fertility. The effects of fertilization on soil fauna communities, however, remain poorly understood. We examined the effects of fertilization form and quantity on the abundance, diversity and composition of soil fauna across an age-sequence of poplar plantations (i.e., 4-, 9- and 20-yr-old) in the coastal regio...
منطقه سه واقع در 110 کیلومتری شمال غرب اصفهان، درقسمت شمالی شهرستان برخوار و میمه و بخش جنوبی شهرستان کاشان واقع می باشد. به منظور بررسی و مطالعات سنگ چینه نگاری و زیست چینه نگاری دونین در این منطقه دو برش نقله و نچفت انتخاب گردید. برش نقله با 200 متر ضخامت عمدتاً شامل آهک با میان لایه های دولومیت می باشدکه به چهار واحد تقسیم می شود. کربونیفر در این ناحیه حضور ندارد و به عنوان گپ چینه شناسی م...
