The role of fragmentation and landscape changes in the ecological release of common nest predators in the neotropics
(PeerJ, 2014-07)
Loss of large mammalian carnivores may allow smaller mesopredators to become abundant and threaten other community members. There is considerable debate about mesopredator release and the role that other potential factors ...
Serosurvey of selected arboviral pathogens in freeranging, two-toed sloths (Choloepus hoffmanni) and three-toed sloths (Bradypus variegatus) in Costa Rica, 2005–07
(Journal of Wildlife Diseases, 2016-10-01)
We screened for antibodies to 16 arboviruses in four populations of free-ranging sloths in Costa Rica. Blood samples were taken from 16 Hoffman's two-toed sloths (HTSs; Choloepus hoffmanni) and 26 brown-throated sloths ...
Characterization of attack events on sea turtles (chelonia mydas and lepidochelys olivacea) by jaguar (panthera onca) in naranjo sector, santa rosa national park, Costa Rica
(International Journal of Conservation Science, 2016-01)
In this study, we examined sea turtles consumption by jaguars and their temporal and spatial distribution at Naranjo beach, Santa Rosa National Park Costa Rica. We include information about sea turtle consumption rate by ...
Inter-trophic food provisioning between sea and land: The jaguar (panthera onca) as provider of sea turtle carcasses to terrestrial scavengers
(International Journal of Conservation Science, 2017-07-10)
A more complete perspective of carrion use by terrestrial vertebrates and about the role of predators in net carrion supply will improve our understanding of critical ecological processes, particularly those associated ...
Factors affecting Jaguar and Puma predation on livestock in Costa Rica
(Wildlife Biology in Practice, 2016-06)
Throughout their range, wild felids in the Americas prey on livestock and this sometimes leads to retaliatory killing. Recently, conservation and research programs focused on such conflicts have recommended mitigation and ...
Jaguars (Panthera onca) increase kill utilization rates and share prey in response to seasonal fluctuations in nesting green turtle (Chelonia mydas mydas) abundance in Tortuguero National Park, Costa Rica
(Mammalian Biology, 2015-03)
Jaguar (. Panthera onca) predation of green turtles (. Chelonia mydas mydas) is now a common occurrence in Tortuguero National Park, Costa Rica. The abundance of green turtles during nesting season ensures a constant ...
Abundance, habitat and body measurements of the rare Long-clawed Mouse (Pearsonomys annectens) in the coastal temperate rainforest of southern Chile
(Studies on Neotropical Fauna and Environment, 2012)
Based on rodent trappings in eight localities from 1998 to 2005 (14,984 trap-nights), we provide detailed information on abundance, habitat and additional body measurements of the Long-clawed Mouse (Pearsonomys annectens), ...
Olive ridley mass nesting ecology and egg harvest at ostional beach, Costa Rica
(Chelonian Conservation and Biology, 2012-06)
The olive ridley sea turtle (Lepidochelys olivacea), a species listed by the International Union for Conservation of Nature as vulnerable, is characterized by its mass-nesting behavior, also known as arribada. For decades, ...
Assessing species traits and landscape relationships of the mammalian carnivore community in a neotropical biological corridor
(Biodiversity and Conservation, 2016-04-06)
Mammalian carnivores play an important role in regulating food webs and ecosystems. While many carnivore populations are facing various threats such as habitat loss and fragmentation, poaching, and illegal trade, others ...
Consensus on Criteria for Potential Areas for Wolf Reintroduction in Mexico
(Conservation Biology, 2012-07-19)
Given the conflict with human interests that in many cases results in the extirpation of large carnivores, acceptance of their reintroduction is a considerable challenge. By the 1980s Mexican wolves (Canis lupus) were ...
