Effectiveness of protected areas for representing species and populations of terrestrial mammals in Costa Rica

Effectiveness of protected areas for representing species and populations of terrestrial mammals in Costa Rica

Costa Rica has one of the greatest percentages (26%) of protected land in the world. The National Protected Areas System (NPAS) of Costa Rica was established in 1976 and currently includes >190 protected areas within seven different protection categories. The effectiveness of the NPAS to represent species, populations, and areas with high species richness has not been properly evaluated....

Distribution, range extension, and conservation of the endemic Black-headed Bushmaster (Lachesis melanocephala) in Costa Rica and Panama

Distribution, range extension, and conservation of the endemic Black-headed Bushmaster (Lachesis melanocephala) in Costa Rica and Panama

The Black-headed Bushmaster, Lachesis melanocephala (Viperidae: Crotalinae), is an endemic pit viper from south-eastern Costa Rica. Despite its importance with regard to medicine and conservation, the ecology and distribution of this species are still poorly known, mainly because it was only recently recognized as a full species and records are scarce across its range. Known only from the Pacific...

Carnivores in silvopastoral systems of Colombia

Conservation value of forest fragments for medium-sized carnivores in a silvopastoral system in Colombia

Silvopastoral cattle ranching is seen as a viable land use management system, which unlike traditional land use systems preserve forested areas and prevent loss of important habitats for carnivores. We evaluated carnivore abundance and habitat use in a 50-year silvopastoral system located in the Cordoba department, Caribbean region of Colombia. Transects and track plots were established both in forest...

The Status of the World’s Land and Marine Mammals: Diversity, Threat, and Knowledge

The Status of the World’s Land and Marine Mammals: Diversity, Threat, and Knowledge

Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment of the conservation status and distribution of the world’s mammals. Data, compiled by 1700+ experts, cover all 5487 species, including marine mammals. Global macroecological patterns are very different for land and marine species but suggest common mechanisms driving diversity and endemism...
