Amphibian and reptile declines over 35 years at La Selva, Costa Rica
Steven M. Whitfield,Kristen E. Bell,Thomas E. Philippi,Mahmood Sasa,Federico Bolaños,Gerardo Chaves,Jay M. Savage,Maureen A. Donnelly +7 more
TL;DR: A systematic community-wide decline in populations of terrestrial amphibians at La Selva Biological Station, a protected old-growth lowland rainforest in lower Central America, is identified and declines are due to climate-driven reductions in the quantity of standing leaf litter, a critical microhabitat for amphibians and reptiles in this assemblage.
Catastrophic Population Declines and Extinctions in Neotropical Harlequin Frogs (Bufonidae: Atelopus)1
Enrique La Marca,Karen R. Lips,Stefan Lötters,Robert Puschendorf,Roberto Ibáñez,José Vicente Rueda‐Almonacid,Rainer Schulte,Christian Marty,Fernando Castro,Jesús Manzanilla-Puppo,Juan E. García-Pérez,Federico Bolaños,Gerardo Chaves,J. Alan Pounds,Eduardo Toral,Bruce E. Young +15 more
TL;DR: Widespread declines and extinctions in Atelopus may reflect population changes in other Neotropical amphibians that are more difficult to survey, and the loss of this trophic group may have cascading effects on other species in tropical ecosystems.
