Panama's frog decline
Crawford and his colleagues describe an analysis of frog species in El Cope, Panama. “We discovered that 30 species were lost, including five undescribed species, representing 41 per cent of total amphibian lineage diversity in El Cope. The irony of increased species discovery coupled with enigmatic population declines in amphibians was recognised at least 10 years ago, “yet until now we have l...
متن کاملIntersexuality and the Cricket Frog Decline: Historic and Geographic Trends
Exposure to anthropogenic endocrine disruptors has been listed as one of several potential causes of amphibian declines in recent years. We examined gonads of 814 cricket frogs (Acris crepitans) collected in Illinois and deposited in museum collections to elucidate relationships between the decline of this species in Illinois and the spatial and temporal distribution of individuals with interse...
متن کاملEndemic Infection of the Amphibian Chytrid Fungus in a Frog Community Post-Decline
The chytrid fungus Batrachochytrium dendrobatidis has been implicated in the decline and extinction of numerous frog species worldwide. In Queensland, Australia, it has been proposed as the cause of the decline or apparent extinction of at least 14 high-elevation rainforest frog species. One of these, Taudactylus eungellensis, disappeared from rainforest streams in Eungella National Park in 198...
متن کاملPopulation Recovery following Decline in an Endangered Stream-Breeding Frog (Mixophyes fleayi) from Subtropical Australia
Amphibians have undergone dramatic declines and extinctions worldwide. Prominent among these have been the stream-breeding frogs in the rainforests of eastern Australia. The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) has been postulated as the primary cause of these declines. We conducted a capture-mark-recapture study over a 7-year period on the endangered Fleay's barred frog...
متن کاملFactors associated with the catastrophic decline of a cloudforest frog fauna in Guatemala.
Comparison of recent and historical surveys of frog populations in cloudforest habitat in Sierra de las Minas, Guatemala, indicated population declines and local extirpation of several species. Pathological exams of diseased tadpoles indicated infection by amphibian chytridiomycosis. The local habitat has been severely altered by recent establishment of large-scale leatherleaf fern production. ...
