Patterns of leaf trait variation underlie ecological differences among sympatric tree species of Damburneya in a tropical rainforest. [PDF]

open access: yesAm J Bot, 2022
Abstract Premise Although ecological differentiation driven by altitude and soil is hypothesized to promote coexistence of sympatric tree species of Damburneya (Lauraceae), the mechanistic role of leaf functional variation on ecological differentiation among co‐occurring species remains unexplored.

Pumas Puma concolor as ecological brokers: a review of their biotic relationships

open access: yesMammal Review, Volume 52, Issue 3, Page 360-376, July 2022., 2022
Pumas Puma concolor are the widest ranging mammal of the Western Hemisphere and one of the world’s largest carnivores. In this review, we aimed to synthesise the evidence on ecological interactions associated with pumas to advance our understanding of their biotic roles in ecosystems across the Americas.

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

open access: yesJournal 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 ...

Collared Peccary Wallows are Hubs of Animal Activity and Diversity in a Central American Wet Forest

open access: yesEcology and Evolution, Volume 15, Issue 2, February 2025.
Collared peccary wallows are used by a diverse assemblage of vertebrates in a Central American tropical wet forest. Wallows had significantly higher vertebrate activity and diversity compared to surrounding forest. Wallow visitors included 13 amphibian, 2 reptile, 11 bird, and 16 mammal species, engaged in behaviors including reproduction, drinking ...

Still little evidence of poleward range shifts in the tropics, but lowland biotic attrition may be underway

open access: yesBiotropica, Volume 57, Issue 1, January 2025.
Based on reviews of more than 450 studies, documented climate‐driven species range shifts within the terrestrial tropics have been exclusively upslope—none poleward, a pattern we attribute to the lack of latitudinal temperature gradients within the tropics, as illustrated here.

Regional differences of functional and taxonomic bird diversity in tropical agroforests of Peru

open access: yesConservation Science and Practice, Volume 6, Issue 6, June 2024.
We studied changes in the functional and taxonomic dissimilarity of bird communities in cacao agroforests and adjacent forests in two landscapes dominated by different forest types (dry tropical forest and subtropical rainforest). We found that the functional traits that are most vulnerable to disappear in agroforests at increasing distance from forest

REGENERACIÓN NATURAL DE LA SELVA ALTA PERENNIFOLIA EN EL PARQUE ESTATAL AGUA BLANCA, MACUSPANA, TABASCO, MÉXICO

open access: yesPolibotánica, 2011
La selva húmeda tropical es uno de los ecosistemas mejor desarrollados y complejos, sin embargo está sufriendo un deterioro muy rápido; como una alternativa para recuperarla se requiere conocer el proceso de regeneración.

Evaluación interdimensional de impactos ambientales sobre la dimensión física ocasionados por cultivos de palma aceitera y la ganadería extensiva en la selva húmeda tropical del Bajo Atrato, Chocó, Colombia

open access: yesGestión y Ambiente, 2011
Este artículo presenta un análisis interdimensional de daños ambientales ocasionados por proyectos palmeros y ganaderos en el Bajo Atrato. El proyecto se desarrolló en dos fases; en la primera, se consolidó la línea base, y en la segunda, se evaluaron ...

Pasture trees in tropical México: the effect of soil nutrients on seedling growth

open access: yesRevista de Biología Tropical, 2006
Environment and seedling community under isolated trees in pastures are different from those in the open pasture. The effect of the pasture trees on the soil nutrients and on the seedling growth were investigated.
