Sensitivity of tropical montane birds to anthropogenic disturbance and management strategies for their conservation in agricultural landscapes

Conservation Biology, Volume 37, Issue 6, December 2023., 2023
Abstract Tropical montane bird communities are hypothesized to be highly sensitive to anthropogenic disturbance because species are adapted to a narrow range of environmental conditions and display high rates of endemism. We assessed avian sensitivity at regional and continental scales for a global epicenter of montane bird biodiversity, the tropical ...

Ecological convergence in phytochemistry and flower–insect visitor interactions along an Andean elevation gradient

Ecology and Evolution, Volume 13, Issue 8, August 2023., 2023
In this study, we detected patterns of ecological convergence along elevation in floral volatiles as well as cost–benefit ratio in seed versus pollinated seeds. Our results suggest that these evolutionary patterns are the result of biotic and abiotic pressures.

Neutral‐based processes overrule niche‐based processes in shaping tropical montane orchid communities across spatial scales

Journal of Ecology, Volume 111, Issue 8, Page 1614-1628, August 2023., 2023
High compositional turnover, even across habitats with the highest degree of human intervention, suggests that both forest‐dwelling and open‐habitat species do not easily disperse across habitats. Species dispersal is the major force of orchid community turnover and might be strongly dependent upon macroevolutionary processes and species life‐history ...

Facilitating biodiversity conservation through partnerships to achieve transformative outcomes

Conservation Biology, Volume 37, Issue 3, June 2023., 2023
Abstract Conservation biology is a mission‐driven discipline that must navigate a new relationship between conservation and science. Because conservation is a social and political as well as an ecological project, conservation biologists must practice interdisciplinarity and collaboration.

Pest risk assessment of Elasmopalpus lignosellus for the European Union

EFSA Journal, Volume 21, Issue 5, May 2023., 2023
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative pest risk assessment of Elasmopalpus lignosellus (Lepidoptera: Pyralidae), the lesser cornstalk borer, for the EU. The assessment considered entry, establishment, spread and impact.

La Propiedad en las Comunidades Andinas

Allpanchis, 2020
Uno de los mayores problemas que confronta el investigador que se interesa en estudiar la propiedad en las comunidades andinas es que no existe sólo una solución. Después de 400 años de haber expuesto a múltiples presiones por parte de la sociedad occidental, el mundo andino, para poder sobrevivir, aprendió a camuflarse bajo el ropaje cultural de los ...
