Genetic divergence and evidence of human-mediated translocation of two-fingered sloths (Choloepus hoffmanni) in Costa Rica. [PDF]

Evol Appl, 2020
Abstract Sloths are notoriously slow and consequently have limited dispersal ability, which makes them particularly vulnerable to the effects of habitat fragmentation and degradation. Sloths in Costa Rica are considered of conservation concern due to habitat loss, livestock production and increasing urbanization. Reintroductions from rescue centres are

Infection with Batrachochytrium dendrobatidis is common in tropical lowland habitats: Implications for amphibian conservation. [PDF]

Ecol Evol, 2019
We conducted a survey testing for the fungal pathogen Batrachochytrium dendrobatidis (Bd) in four lowland sites in Costa Rica to identify local host‐pathogen dynamics and to describe the abiotic environment for this pathogen. We found evidence that lowland study sites exhibit enzootic dynamics with low infection intensity and moderate to high ...

Phylogeography and invasion history of Aedes aegypti, the Dengue and Zika mosquito vector in Cape Verde islands (West Africa). [PDF]

Evol Appl, 2019
Abstract Aedes‐borne arboviruses have spread globally with outbreaks of vast impact on human populations and health systems. The West African archipelago of Cape Verde had its first outbreak of Dengue in 2009, at the time the largest recorded in Africa, and was one of the few African countries affected by the Zika virus epidemic.

Population structure of a vector of human diseases: Aedes aegypti in its ancestral range, Africa. [PDF]

Ecol Evol, 2018
We have detected distinct genetic structuring of populations of the major vector of human diseases Aedes aegypti in its native range, Africa. Both isolation by distance and long‐range anthropogenic migration are observed. Strong evidence indicates Angola populations gave rise to the species outside Africa.

Good data are not enough: Understanding limited information use for climate risk and food security management in Guatemala

Climate Risk Management, 2020
Climate extremes are one of the main drivers of acute food insecurity. In Guatemala, acute food insecurity reaches alarming levels when the usual dry period during the bimodal rainy seasons is extended or starts earlier than expected.

Clasificación geomecánica del macizo rocoso, Dos Montañas, Siquirres, Costa Rica

Revista Geológica de América Central, 2011
Searching for future possibilities in the production of hydroelectric energy in Costa Rica, the site known as Dos Montanas represents one of the most places to develop a hydropower project. This study determines the rock mass quality of the site, the calculus of support pressure, not only for the roof, bur also for walls from underground excavations ...
