From May to November 2003, at five selected sites of the 'Siebengebirge', a nature reserve near Bonn, Germany, data on microclimate, pedology, plant sociology and tick abundance were collected weekly and correlated. A total of 2832 host-seeking Ixodes ricinus (2660 nymphs and 172 adults) were collected, with maximal abundance in June and a minor second increase in abundance in August. The spati...

Doğu Anadolu Bölgesi ve üniversite kampüs alanlarında ilk kez yapılan bu briyososyolojik çalışmada, Fırat Üniversitesi Merkez Kampüsünde bulunan Ulmus minor ağaçlarının epifitik briyofit vejetasyonu araştırılmıştır. 2021 yılının farklı vejetasyon dönemlerinde, ağaç gövdelerinden alınan örneklik alanların, klasik Braun-Blanquet metodu kullanılarak değerlendirilmesi sonucunda; Orthotrichetum pumi...

Habitat corridors are important tools for maintaining connectivity in increasingly fragmented landscapes, but generally they have been considered in single-species approaches. Corridors intended to facilitate the movement of multiple species could increase persistence of entire communities, but at the likely cost of being less efficient for any given species than a corridor intended specificall...

calanoid, cyclopoid, harpacticoid and poecilostomatoid copepods were investigated over the year at five stations in the chabahar bay, oman sea. this area is under the influence of the indian ocean seasonal monsoons. the samples were collected using vertical plankton tows with 100 µm mesh nets. copepods were identified into 20 genera and 59 species. calanoid formed about 15% to 62% and cyclopoid...

in this survey, 54 specimens of common carp (cyprinus carpio) were collected from anzali wetland between august 2011 and july 2012. after recording biometric characteristics, routine necropsy and parasitology methods were used. totaly, 3165 individuals of parasites were isolated and identified from common carp. parasitofauna consisted of 10 species as follows: two protozoans, ichthyophthirius m...

As delphinid populations become increasingly exposed to human activities we rely on our capacity to produce accurate abundance estimates upon which to base management decisions. This study applied mark-recapture methods following the Robust Design to estimate abundance, demographic parameters, and temporary emigration rates of an Indo-Pacific bottlenose dolphin (Tursiops aduncus) population off...

In the present paper a phytosociological study on dry grassland communities identified in western sector of Murgia Plateau (Murgia delle Gravine) and Lucanian badlands territory is presented. Forty vegetation releves were carried out using Braun-Blanquet approach. Two new associations characterized by therophytic dominance, namely Lysimachio foeminae-Atractylidetum cancellatae Campanulo erini-M...

Marine ecosystems are exposed to a range of human-induced climate stressors, in particular changing carbonate chemistry and elevated sea surface temperatures as a consequence of climate change. More research effort is needed to reduce uncertainties about the effects of global-scale warming and acidification for benthic microbial communities, which drive sedimentary biogeochemical cycles. In thi...

The latest solar atmosphere models include non-LTE corrections and 3D hydrodynamic convection simulations. These models predict a significant reduction in the solar metal abundance, which in turn leads to a serious conflict between helioseismic data and the predictions of solar interiors models. We demonstrate that the helioseismic constraints on the surface convection zone depth and helium abu...
