Population Declines and Priorities for Amphibian Conservation in Latin America
Abstract: Although dramatic amphibian population declines have been reported worldwide, our understanding of the extent of the declines in Latin America, where amphibian diversity is high, is limited
Amphibian and reptile declines over 35 years at La Selva, Costa Rica
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.
The amphibian chytrid fungus along an altitudinal transect before the first reported declines in Costa Rica
Amphibian populations have declined and disappeared in protected and apparently undisturbed areas around the world, especially in montane areas of the tropics. The amphibian chytrid fungus,
Catastrophic Population Declines and Extinctions in Neotropical Harlequin Frogs (Bufonidae: Atelopus)1
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.
Distribution models for the amphibian chytrid Batrachochytrium dendrobatidis in Costa Rica: proposing climatic refuges as a conservation tool
Aim: We use novel data on the occurrence of the amphibian chytrid fungus Batrachochytrium dendrobatidis in Costa Rica to model its potential distribution in that country. Location: Lowland and
Diatoms and Other Epibionts Associated with Olive Ridley (Lepidochelys olivacea) Sea Turtles from the Pacific Coast of Costa Rica
The present study is the first of the epizoic diatom community covering the olive ridley turtle's (Lepidochelys olivacea) carapace and the first describing diatoms living on sea turtles in general, with the primary objective of providing detailed information on turtle epibiotic associations.
Salamanders from the eastern Cordillera de Talamanca, Costa Rica, with descriptions of five new species (Plethodontidae: Bolitoglossa, Nototriton, and Oedipina ) and natural history notes from recent
Five new species of lungless salamanders from high mountain habitats along the border between Costa Rica and Panama are described and phylogenetic hypotheses for the new taxa (with the exception of the Oedipina) and their rel-atives based on mitochondrial DNA sequence data are presented.

Tamaño, estructura y distribución de una población de Crocodylus acutus (Crocodylia: Crocodilidae) en Costa Rica
Spatial distribution and population size of Crocodylus acutus were estimated during the dry season (January-April) of 1989 and 1990 in the Grande de Tarcoles rivet, SO Co sta Rica. A high den sity (
A new species of dink frog (Anura: Eleutherodactylidae: Diasporus ) from Cordillera de Talamanca, Costa Rica
A new dink frog species of the genus Diasporus (Eleutherodactylidae) is described from the Cordillera de Talamanca in Costa Rica. The new species shows an amazing polymorphism in the dorsal and
