Mammal defaunation leads to biotic homogenization of plant communities in tropical rainforests. [PDF]

Ecology
Abstract Biotic homogenization is the process in which species communities become increasingly similar across different regions over time. This phenomenon has substantial ecological, evolutionary, and economic implications, primarily driven by human activities such as habitat destruction, invasive species introduction, and climate change.

Coyote Range Expansion in the Human-Modified Tropics of Mesoamerica. [PDF]

Ecol Evol
Coyotes have expanded their range into southeastern Mexico, Guatemala, and Belize, increasingly occupying human‐modified landscapes. This expansion is ongoing, with rising detection rates over time and records in both disturbed and forested environments, highlighting a paradox where anthropogenic change enables native carnivore expansion.

Ecological Processes Shaping Marine Microbial Assemblages Diverge Between Equatorial and Temperate Time-Series. [PDF]

Mol Ecol
ABSTRACT Marine microbial communities are structured by a complex interplay of deterministic and stochastic processes, yet how these vary across latitudes remains poorly understood. Most long‐term microbial observatories are restricted to temperate regions, limiting our ability to assess latitudinal contrasts in microbial dynamics.

Limnology of Tropical Mountain Lakes: Analysis of the hydromorphological, physical and biogeochemical variability of the Cajas Massif lake district [PDF]

, 2023
[eng] High-mountain tropical lakes in the South American continent are located in the upper part of the Andes range in the equatorial zone (Venezuela, Colombia, Ecuador, Peru, and Bolivia), altitudinally, usually above the forest line (3000-5000 m a.s.l.)

Regional Pelagic Rotifer Biodiversity in a Tropical Karst Lake District

Diversity, 2020
The species richness, composition, abundance, and biomass of pelagic rotifers were determined in 17 karst lakes of the “Lagunas de Montebello” National Park, Chiapas, Mexico. The species richness of the region (21 species) and single lakes (1–12 species)

Upwelling increases net primary production of corals and reef-wide gross primary production along the Pacific coast of Costa Rica

Frontiers in Marine Science, 2015
Photosynthetic production is a key ecosystem service provided by tropical coral reefs, but knowledge about the contribution of corals and other reef-associated organisms and the controlling environmental factors is scarce.

Turnover Drives High Benthic Macroinvertebrates’ Beta Diversity in a Tropical Karstic Lake District

Diversity, 2022
Beta diversity is useful to explain community assembly across landscapes with spatial variation. Its turnover and nestedness components help explain how beta diversity is structured across environmental and spatial gradients.

Variation in cell densities and pigment concentrations of symbiotic dinoflagellates in the coral Pavona clavus in the eastern Pacific (Costa Rica)

Ciencias Marinas, 2008
The density and chlorophyll concentrations of symbiotic dinoflagellates (zooxanthellae) in the eastern Pacific coral Pavona clavus were monitored over the transitional period from rainy to dry season in a seasonal upwelling region and in a nonupwelling ...

Habitat expansion of a tropical chironomid by seasonal alternation in use of littoral and profundal zones

Journal of Limnology, 2022
The consistent warming of tropical lakes at all depths causes rapid development and long persistence of seasonal hypoxia in the hypolimnion, which greatly reduces the biodiversity of hypolimnetic benthic invertebrates. Full mixing of the water column in
