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

open access: yesBiol 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]

open access: yesGlob 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.

Amphibians and Reptiles Exhibit Different Ecological and Evolutionary Spatial Patterns in the Amazon Basin. [PDF]

open access: yesEcol Evol
This study investigates the spatial variability of ecological and evolutionary patterns in amphibian and reptile lineages within the Amazon Basin. Our findings highlight distinct diversity patterns across lineages and ecoregions. ABSTRACT Understanding spatial variability in ecological and evolutionary patterns is key to Amazonian biodiversity ...

Respiración edáfica de los suelos de páramo de Pungalá-sub cuenca río Chambo. [PDF]

open access: yes, 2021
La respiración edáfica (RE) es la producción de CO2 emanado como producto de la respiración de los organismos del suelo y es un indicativo importante del estado de fertilidad del mismo.

Movement Strategies of Neotropical Nectarivorous Birds: Insights From High‐Andean Hummingbirds and Flowerpiercers

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Nectar is a highly variable, mostly unpredictable resource in tropical mountains. How do nectarivorous birds such as this male Great Sapphirewing cope? Fine‐scaled tracking of hummingbirds and flowerpiercers shows flexibility in daily movement strategies in the high Andes, possibly in response to fluctuating local conditions such as weather and ...

The Diamesinae (Diptera: Chironomidae) in High‐Altitude Andean Streams Using Morphological and Molecular Approaches

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Diamesinae is one of the 11 subfamilies of Chironomidae, characterized by its preference for cold waters, typically found in mountainous regions. For the genus Limaya, two OTUs were identified using all methods, one for Ecuador and one for Peru. Seven OTUs were identified for the genus Paraheptagyia.

Water temperature and catchment characteristics drive variation in carbon dioxide and methane emissions from small ponds in a peatland‐rich, high‐altitude tropical ecosystem

open access: yesLimnology and Oceanography, Volume 70, Issue 12, Page 3832-3849, December 2025.
Abstract Inland waters release significant amounts of carbon into the atmosphere, with small ponds acting as hot spots. High variability and limited research make emissions from small waterbodies a major source of uncertainty, especially in underrepresented tropical ecosystems where unique drivers remain poorly understood.

The Overlooked Link Between Different Resource Partitioning Strategies and Plant Species Richness in Tropical Alpine Ecosystems

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 12, December 2025.
ABSTRACT Aim Species coexistence is based on resource partitioning and modulates biodiversity patterns across climates, latitudes and altitudes. Resource partitioning can occur via niche size or separation in the geographic range or ecological niche. While resource partitioning promotes biodiversity, the impact of different partitioning strategies on ...
