Are snake populations in widespread decline?
Long-term studies have revealed population declines in fishes, amphibians, reptiles, birds and mammals. In birds, and particularly amphibians, these declines are a global phenomenon whose causes are often unclear. Among reptiles, snakes are top predators and therefore a decline in their numbers may have serious consequences for the functioning of many ecosystems. Our results show that, of 17 sn...
متن کاملRapid assessments of amphibian diversity
More than 6400 amphibian species are known worldwide, with more than 50 new species being described in just the fi rst half of 2008 (AmphibiaWeb 2008). Many of these species are threatened or declining and more than 150 may have recently become extinct (IUCN 2006). Such rates of species loss are far greater than the historic background extinction rate for amphibians (e.g. McCallum 2007; Roelant...
متن کاملDNA barcoding applied to ex situ tropical amphibian conservation programme reveals cryptic diversity in captive populations.
Amphibians constitute a diverse yet still incompletely characterized clade of vertebrates, in which new species are still being discovered and described at a high rate. Amphibians are also increasingly endangered, due in part to disease-driven threats of extinctions. As an emergency response, conservationists have begun ex situ assurance colonies for priority species. The abundance of cryptic a...
متن کاملLarge-scale phylogenetic analyses reveal the causes of high tropical amphibian diversity.
Many groups show higher species richness in tropical regions but the underlying causes remain unclear. Despite many competing hypotheses to explain latitudinal diversity gradients, only three processes can directly change species richness across regions: speciation, extinction and dispersal. These processes can be addressed most powerfully using large-scale phylogenetic approaches, but most pre...
متن کاملAmphibian diversity: decimation by disease.
D isease emergence and biodiversity loss are among the most pervasive environmental problems confronting science and society. Widespread and dramatic losses of amphibian populations and species represent the deadly intersection between these issues (1), as illustrated by the work of Lips et al. (2) in this issue of PNAS. Amphibians are one of the most imperiled groups of vertebrates, with nearl...
