Functional diversity of snakes is explained by the landscape composition at multiple areas of influence. [PDF]

Ecol Evol, 2023
This study investigated the impact of roads and landscape composition on the functional diversity of snakes in the Orinoco region of Colombia. The results suggest that landscape composition affects the functional diversity of both road‐killed snakes and those inhabiting the adjacent vegetation within an area of influence ranging from 250 to 2000 m.

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.

Niche-based approach to explore the impacts of environmental disturbances on biodiversity. [PDF]

Conserv Biol
Abstract Globally, species are increasingly at risk from compounding threatening processes, an increasingly prominent driver of which is environmental disturbances. To facilitate effective conservation efforts following such events, methods that evaluate potential impacts across multiple species and provide landscape‐scale information are needed to ...

Validating graph‐based connectivity models with independent presence–absence and genetic data sets

Conservation Biology, Volume 37, Issue 3, June 2023., 2023
Abstract Habitat connectivity is a key objective of current conservation policies and is commonly modeled by landscape graphs (i.e., sets of habitat patches [nodes] connected by potential dispersal paths [links]). These graphs are often built based on expert opinion or species distribution models (SDMs) and therefore lack empirical validation from data

Habitat loss increases seasonal interaction rewiring in plant–pollinator networks

Functional Ecology, Volume 36, Issue 10, Page 2673-2684, October 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding the flexibility of interactions and network rewiring (i.e. reassembly of interactions due to partner‐switching) is necessary to comprehend how future anthropogenic changes will affect interspecific interactions and the functioning of communities.

El entorno construido en los programas diseñados para promover la actividad física entre las niñas, niños y jóvenes latinos que viven en Estados Unidos y América Latina

Obesity Reviews, Volume 22, Issue S5, Octubre 2021., 2021
Resumen Prevenir la obesidad entre los jóvenes latinos que viven en Estados Unidos y en países latinoamericanos requiere reconocer la especificidad de los contextos y las interacciones entre actividad física (AF) y entorno construido (EC). El objetivo de este artículo es avanzar en la agenda de investigación sobre el EC y la AF con el fin de prevenir ...

Small instream infrastructure: Comparative methods and evidence of environmental and ecological responses

Ecological Solutions and Evidence, Volume 1, Issue 2, December 2020., 2020
We reviewed evidence on environmental and ecological responses to dams, weirs, and culverts, finding that most studies (78% of 87) evaluated dams or weirs, and that more than half of all evaluations reported negative environmental or ecological responses to the three types of infrastructure. Abstract 1.
