Notes of diet in highland snakes rhadinaea calligaster and rhadinella godmani (Squamata:Dipsadidae) from Costa Rica
(Sociedad Herpetologica Mexicana, 2020-11)
Se reportan observaciones de la dieta de dos especies de serpientes elegantes: Rhadinaea calligaster fue observada depredando una salamandra del género Bolitoglossa; también se reportan observaciones sobre ...
Disadvantages of living in a populous neighborhood for sit-andwait predators: Competition for space reduces pit-trap size in antlion larvae
(Blackwell Publishing Ltd, 2020-11-01)
The study of how trap design responds to biotic and abiotic conditions can help to
understand the selective forces affecting the foraging of trap-building organisms.
We experimentally tested whether pit design can be ...
Detección de la infección por Brucella ceti en cetáceos mediante PCR-Alta Resolución de Fusión: pautas para el manejo de delfines encallados
(Universidad Nacional, Costa Rica, 2020)
Este trabajo describe la aplicación de la Reacción en Cadena de la Polimerasa con Alta Resolución de la Temperatura de Fusión (PCR-HRM) como herramienta de apoyo en la identificación de aislamientos de bacterias del género ...
Evaluación de cultivos ex situ de dos especies de corales formadores de arrecife (Porites lobata y Pocillopora damicornis)
(Universidad Nacional (Costa Rica), 2021)
Los arrecifes de coral constituyen uno de los sistemas biológicos más productivos y biodiversos del planeta, al mismo tiempo que se les reconoce como ecosistemas en alto riesgo de deterioro funcional, susceptibles a los ...
Evaluating watershed health in Costa Rican national parks and protected areas
(Springer Science and Business Media Deutschland GmbH, 2020-08-11)
Although the biodiversity of Costa Rican national parks, forests, and wetlands has been extensively surveyed, there has not
been a watershed assessment that refects their baseline water quality. Undoubtedly, the infux of ...
Headwaters drive streamflow and lowland tracer export in a large-scale humid tropical catchment
(John Wiley and Sons Ltd, 2020)
Headwaters are generally assumed to contribute the majority of water to downstream users, but
how much water, of what quality and where it is generated are rarely known in the humid tropics.
Here, using monthly monitoring ...
Residual nitrite in processed meat products in Costa Rica: Method validation, long-term survey and intake estimations
(Elsevier Ltd, 2021-05-12)
Ingestion of high amounts of nitrite due processed meat consumption could produce negative effects in human health. Here, we investigate long-term residual sodium nitrite content in processed meat products in Costa Rica ...
End member and Bayesian mixing models consistently indicate near-surface flowpath dominance in a pristine humid tropical rainforest
(John Wiley & Sons Ltd, 2021)
The impacts of forest conversion on runoff generation in the tropics have received much
interest, but scientific progress is still hampered by challenging fieldwork conditions and
limited knowledge about runoff mechanisms. ...
Reverse circulation in Bahía Santa Elena, North Pacific of Costa Rica
(Elsevier B.V., 2021-02-10)
This work describes the water circulation of Bahía Santa Elena using velocity fields and hydrographic data obtained from a ship-mounted Acoustic Doppler Current Profiler and a vertical profiler Conductivity–Temperature–Depth ...
A preliminary isotope-based evapotranspiration partitioningapproach for tropical Costa Rica
(John Wiley and Sons Ltd, 2021-07)
Spatially and seasonally distributed information on transpiration (T) fluxes is limited in the tropics. Here, we applied a coupled isotope mass balance model to separate water fluxes of T and evapotranspiration (ET) from ...
