Article
Full-text available
The high proportion of declining amphibian populations and species without ecological information makes it imperative to conduct research on their population biology, natural history and habitat requirements. We describe the abundance, age structure, activity patterns and microhabitat of four populations of Rhinella macrorhina, a threatened toad fr...
Article
Full-text available
Intraspecific morphological variation may correspond to behavioral variation that helps determine the nature of species interactions. Color variation among populations of variably toxic organisms has been shown to associate with alternative anti-predator behaviors. However, the effects of these alternative behavioral tendencies on the outcomes of i...

We sampled the snake fauna in 13 landscapes along 80 km of highway and in the adjacent vegetation cover in the Colombian Llanos. We registered 119 snakes belonging to 33 species. Traffic levels significantly influenced rates of snake road kill, while adjacent vegetation cover, rainfall seasonality, and landscape structure and composition did not. W...

This dataset is the first effort to combine the audio biodiversity of a taxonomic group in a selected location, the Boyacá department in Colombia. We conducted a detailed review of the sound recordings for birds from the Boyacá department within three repositories, the environmental sound collection of the Humboldt Institute, the Macaulay Library o...
Book
Full-text available
Este libro surge como resultado del trabajo que realizaron conjuntamente científicos, comunidades locales e instituciones en el proyecto Expediciones Boyacá Bio y sintetiza los principales hallazgos, resultado de 17 expediciones científicas, de interés particular para los tomadores de decisiones para la gestión de la biodiversidad en el departament...
Presentation
Full-text available
Existen métodos tradicionales para abordar estudios en biodiversidad de aves. Sin embargo, novedosas técnicas y aproximaciones permiten entender dicha diversidad desde otro punto de vista. Evaluamos la diversidad acústica de las aves del departamento de Boyacá, a partir de una revisión de repositorios acústicos ornitológicos y exploraciones recient...
Conference Paper
Background/Question/Methods Novel insights into mechanisms influencing community assembly can be gained by examining the influences of intraspecific phenotypic variation on species interactions. Intraspecific morphological variation may associate with behaviors that mediate the strength of species interactions, and may ultimately affect species d...
Conference Paper
Background/Question/Methods Intraspecific phenotypic variation associates with behaviors that can mediate the strength of species interactions, and may ultimately affect species distributions and abundances. Polymorphic species provide an effective tool to help us better understand the potential effects of intraspecific phenotypic variation in sp...
Conference Paper
Full-text available
Background/Question/Methods Emerging infectious diseases (EIDs) may reduce biodiversity and account for species extinctions. Therefore, it is urgent to understand the temporal and spatial dynamics of EIDs and to identify the factors associated with these dynamics. We studied seasonal and elevational patterns of prevalence and intensity of Batracho...
Thesis
Batrachochytrium dendrobatidis (Bd) has contributed to population declines and extinction of amphibians worldwide. Disease-caused extinction is rare, but may occur where reservoirs exist or where transmission is independent of host density. Because some species persist after Bd epizootic events, they may act as potential reservoirs of the infection...

Project
Investigación asociada a las colecciones biológicas
Project
Realizar la caracterización de la biodiversidad (fauna y flora) en 12 puntos del Departamento de Boyacá, Colombia, a partir de muestreos biológicos en 17 expediciones y de talleres de ciencia participativa con las comunidades en 7 expediciones, con el objetivo de identificar su conocimiento de la biodiversidad, los usos tradicionales que le dan a esta, las amenazas que esta enfrenta y los servicios ecosistémicos de los hábitat que habitan.
Project
Within reptiles, snakes are the group most affected by roads due to factors intrinsic to their ecology and their complex patterns of movement, which leads them to use different habitat types for basking, shelter and foraging. In this study we propose to identify how landscape heterogeneity, seasonality, and ecological aspects of different snake species associate with patterns of mortality on a road in this savana ecosystem. Such information is essential to help mitigate the impacts of roads on snake communities.
