Occupancy and probability of detection of the introduced population of Eleutherodactylus coqui in Turrialba, Costa Rica
(Firenze University Press, 2022-07-28)The Puerto Rican Common coqui frog (Eleutherodactylus coqui) has a long history as an invasive species in places such as Hawaii. Since its introduction in Costa Rica, scarce information is available to understand why and ... -
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, ... -
Population status of terrestrial mammals’ in two protected areas in the west central region of Costa Rica [Estado poblacional de mamíferos terrestres en dos áreas protegidas de la región central occidental de Costa Rica]
(Revista de Biología Tropical, 2017-11-16)In the West Central Region of Costa Rica, there are plenty of forests under public and private protection; however, they are increasingly exposed to fragmentation. This is the first report about species richness and the ... -
Population status, connectivity, and conservation action for the endangered Baird's tapir
(Elsevier Ltd, 2020-05)Although many large mammals currently face significant threats that could lead to their extinction, resources for conservation are often scarce, resulting in the need to develop efficient plans to prioritize conservation ... -
Precipitous decline of white-lipped peccary populations in Mesoamerica
(Elsevier Ltd, 2020-02)Large mammalian herbivores are experiencing population reductions and range declines. However, we lack regional knowledge of population status for many herbivores, particularly in developing countries. Addressing this ... -
Reproduction of white-tailed deer in a seasonally dry tropical forest of Costa Rica: A test of aseasonality
(Oxford University Press, 2020-02-21)The reproductive season of white-tailed deer (Odocoileus virginianus) has been hypothesized to be aseasonal south of about 14°–18°N latitude, where annual variation in day length is low. We tested this idea by using camera-trap ... -
Scavenging on sea turtle carcasses by multiple jaguars in northwestern Costa Rica
(Therya, 2016)Information on scavenging by jaguars is scarce, dispersed and little documented in the scientific literature, producing a shallow understanding of this phenomenon. Therefore, the aim of this paper is to describe the behavior ... -
Seasonal use of waterholes and pathways by macrofauna in the dry forest of Costa Rica
(Cambridge University Press, 2019-03-01)Temporal and spatial scarcity of water in semi-arid and seasonal ecosystems often leads to changes in movements and behaviour of large vertebrates, and in the neotropics this dynamic is poorly understood due to logistical ... -
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 ... -
Soundscape structure in forests surrounded by protected and productive areas in central Costa Rica
(Universidad Nacional, Costa Rica, 2023-03-09)Ecosystems are under a multitude of pressures, including land-use change, overexploitation, pollution, and climate change. Most studies, resources, and conservation efforts are allocated to protected areas, while anthropogenic ... -
Temporal and spatial resource use by female three-toed sloths and their young in an agricultural landscape in Costa Rica
(Revista de Biologia Tropical, 2011-12)The information on ecological behavior of wild sloths is very scarce. In this study we determined the home ranges and resources used by three adult female three-toed sloths (Bradypus variegatus) and their four young in ... -
The big free-tailed bat, Nyctinomops macrotis (Gray, 1839), in central America [El murciélago grande de cola libre, Nyctinomops macrotis (Gray, 1839), en Centro América]
(Mastozoologia Neotropical, 2016-12)The big free-tailed bat, Nyctinomops macrotis, is a large molossid with a discontinuous distribution in the southwestern United States and most of Mexico (northern range), and northern South America (southern range). In ... -
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 ... -
Variation in abundance and habitat relationship of three understory insectivorous birds in a disturbed landscape of Neotropical dry forest of Colombia
(BioMed Central Ltd, 2020-09-02)Background: Evaluating relationships between avian populations and their habitat is important for understanding the biology of these species and for management decisions that improve the efectiveness of restoration ... -
Vegetation, bird and soundscape characterization: a case study in Braulio Carrillo National Park, Costa Rica
(Instituto de investigación de recursos biológicos Alexander von humboldt, 2021)We assessed the structural complexity of vegetation, birds and soundscapes in two areas of Braulio Carrillo National Park, Costa Rica, with different road exposure, as baseline information for conservation and management. We ... -
Wildlife diversity and relative abundance among a variety of adjacent protected areas in the northern Talamanca Mountains of Costa Rica
(MDPI AG, 2020-04-01)Protected areas are intended to achieve the long-term conservation of nature, but not all such areas are equal in their effectiveness because of their varying regulation of human activities. In Costa Rica, we assessed ...
