Tracking Small Animals in Complex Landscapes: A Comparison of Localisation Workflows for Automated Radio Telemetry Systems. [PDF]

Ecol Evol
Automated radio telemetry grids provide the possibility of studying movement of small animals at very fine spatial scales, but the influence of rugged terrains and vegetation on localisation error curtails the applicability of this technology. In this study, we present a comparative workflow to reduce error and show how selecting higher radio signal ...

Pollination ecology in the tropical Andes: moving towards a cross-scale approach. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Tropical Land-Use Change Disrupts Zeta-Diversity Across Taxa. [PDF]

Glob Chang Biol
We studied birds, dung beetles, and orchids across natural and human‐transformed habitats in the Colombian Andes to understand how land‐use change affects biodiversity. We found that deforestation simplifies ecological communities and reduces both rare and widespread species, especially orchids.

Intraspecific variation in pollination ecology due to altitudinal environmental heterogeneity. [PDF]

Ecol Evol
Plant populations in different eco‐regions differed in pollination ecology strategies. These population differences are not explained by differences in pollinator assembly, but by environmental heterogeneity. Abstract Plant‐pollinator interactions are constrained by floral traits and available pollinators, both of which can vary across environmental ...

How tectonic, volcanic and climatic processes in Andean ‘sky islands’ shaped the diversification of endemic ground beetles

Journal of Biogeography, Volume 49, Issue 11, Page 2077-2090, November 2022., 2022
Abstract Aim The Andean superpáramo ecosystem, above c. 4200 m a.s.l., currently forms an archipelago of isolated ‘sky islands’ which provides a unique setting to study biogeography. However, there is still a poor understanding of how past geological events, together with past climatic changes, have shaped the distribution of life in this ecosystem ...

Frailejones en peligro.

, 2021
Los frailejones (subtribu Espeletiinae, familia Asteraceae) son posiblemente las más importantes y carismáticas plantas del ecosistema de páramo. Con 90 especies reconocidas, 78 de las cuales son endémicas, Colombia tiene un papel fundamental en su ...
