The Endangered Egyptian Vulture Neophron percnopterus congregates in communal roosts in the wintering areas and where food availability is high, where even a single threat might lead to substantial population declines. Thus, more research on the congregation sites is needed for timely detection of threats and effectively directed conservation measures. We studied bird numbers, use of roosting substrates and roosting habitat of wintering Egyptian Vultures in Ethiopia. Vultures were counted using the road-count technique in 2009, 2010 and 2013 along c. 600 km of roads in the Afar region. Over 1 000 individuals were counted each year and the sites with the highest congregations were identified. Nearly half of the birds were adults and the majority roosted on bird-safe types of electric pylons. Most of the Egyptian Vultures were found below 500 m above sea level, in bare areas, open savannas or grasslands, and their abundance was negatively related to the amount of cover of bush vegetation. The distribution of roosting birds was not affected by distance to human settlements. To avoid disasterous effects on the population of the Egyptian Vultures, we strongly recommend that the sites sheltering the highest numbers of roosting birds should be included in the Important Bird Area network, the use of poisons should be banned, and dangerous power lines should be insulated or substituted with safer types.
The ‘smooth newt’, the taxon traditionally referred to asLissotriton vulgaris, consists of multiple morphologically distinct taxa. Given the uncertainty concerning the validity and rank of these taxa,L. vulgarissensu lato has often been treated as a single, polytypic species. A recent study, driven by genetic data, proposed to recognize five species,L. graecus,L. kosswigi,L. lantzi,L. schmidtleriand a more restrictedL. vulgaris. The Carpathian newtL. montandoniwas confirmed to be a closely related sister species. We propose to refer to this collective of sixLissotritonspecies as the smooth newt orLissotriton vulgarisspecies complex. Guided by comprehensive genomic data from throughout the range of the smooth newt species complex we 1) delineate the distribution ranges, 2) provide a distribution database, and 3) produce distribution maps according to the format of the New Atlas of Amphibians and Reptiles of Europe, for the six constituent species. This allows us to 4) highlight regions where more research is needed to determine the position of contact zones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
