¿Qué es un bosque nativo en la Argentina? Marco conceptual para una correcta definición de acuerdo con las políticas institucionales nacionales y el conocimiento científico disponible

Ecología Austral, 2023
Los bosques nativos son los ecosistemas naturales que más atención reciben de la sociedad en relación con su conservación y manejo. El alcance de la definición de bosque nativo ha cambiado con el tiempo, lo cual afecta la implementación de diversos ...

Bird species occupancy trends in Southeast Mexico over 1900–2020: Accounting for sighting record absences

Journal of Animal Ecology, Volume 92, Issue 3, Page 606-618, March 2023., 2023
This article accounts for species absences before occupancy analyses, addressing a long‐standing concern of whether absence is true or due to low sampling effort. The authors affiliate long‐term bird species trends with functional traits in a lowland tropical rainforest landscape in southeast Mexico to help guide land management and conservation ...

Hummingbird diversity in a fragmented tropical landscape in the Chocó biogeographic zone

Biotropica, Volume 55, Issue 2, Page 418-429, March 2023., 2023
We investigated habitat‐ and site‐level patterns of diversity, and community composition of hummingbirds between continuous forest (transects n = 16 in ~3500 ha) and more disturbed surrounding fragments (n = 39, 2.5–48.0 ha) in the Chocó rainforest of northwestern Ecuador. We found higher hummingbird species richness in forest fragments relative to the

Lizard thermoregulation revisited after two decades of global warming

Functional Ecology, Volume 36, Issue 12, Page 3022-3035, December 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract Although the effects of global warming on thermoregulation are usually explored using predictions of climate envelop modelling, such effects should best be analysed empirically, studying the same population with the same methods after a long enough period of temperature

Evaluación del cambio del paisaje boscoso y su impacto en la distribución de Dipsas elegans en el norte de Ecuador

Investigaciones Geográficas, 2023
La cuenca hidrográfica del río Mira en Ecuador posee una alta biodiversidad, sin embargo, el uso intensivo del suelo ha ocasionado cambios en el paisaje y ha generado alteraciones en la distribución de especies.

Forest loss and treeless matrices cause the functional impoverishment of sapling communities in old‐growth forest patches across tropical regions

Journal of Applied Ecology, Volume 59, Issue 7, Page 1897-1910, July 2022., 2022
In agreement with the LMFTS hypothesis, our results confirm that landscape modifications in regions undergoing high and long‐lasting deforestation greatly impoverish the functional composition and diversity of sapling communities. The shift from communities composed mainly by conservative attributes towards communities with a higher prevalence of ...

Directional changes over time in the species composition of tropical vascular epiphyte assemblages

Journal of Ecology, Volume 110, Issue 3, Page 553-568, March 2022., 2022
Directionality in the temporal changes of epiphyte assemblages suggests that niche‐based mechanisms dominate these temporal changes. Host size over host identity is the most important environmental filter for epiphyte assemblages establishment. Tree Vectors Pack by Pixeden.com (https://www.freevector.com/trees‐illustrations). Abstract Understanding the

Life on a leaf: The development of spatial structure in epiphyll communities

Journal of Ecology, Volume 110, Issue 3, Page 619-630, March 2022., 2022
Using epiphyll spatial patterns to detect changes in ecological drivers that shape life on a leaf, this study shows how these miniature ecological communities living on rainforest leaves can be used as a model system for community dynamics. Abstract The spatial structure of biotic communities can be shaped by niche‐based or stochastic processes, and ...
