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.

Antagonistic and synergistic responses to solar ultraviolet radiation and increased temperature of phytoplankton from cenotes (sink holes) of the Yucatán Peninsula, México [PDF]

, 2015
Cenotes (sink holes) are karstic formations characteristic of the Yucatán Peninsula and are the main source of fresh water in the region. Because of their tropical location, they receive high levels of solar radiation and are exposed to high temperatures.

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)

Colonization of a Neotropical Reservoir (Córdoba, Argentina) by Ceratium hirundinella (O. F. Müller) Bergh [PDF]

, 2005
Blooms of Ceratium hirundinella (O. F. Müller) Bergh. have been detected in different water bodies in the Neotropical Region since 1990. The colonization began in southern lakes, and during the last decade the dinoflagellate arrived and bloomed in ...

Deposition, burial and sequestration of carbon in an oligotrophic, tropical lake

Journal of Limnology, 2014
The amount of biogenic carbon that may be deposited, buried and eventually preserved (sequestered) in the sediments of a tropical, oligotrophic lake, was evaluated based on i) the temporal variation of the particulate organic carbon (POC) concentration ...

Efecto de la composición de la dieta sobre el desarrollo del mosquito de inundación Ochlerotatus (Ochletotatus) albifasciatus (Macquart) (Diptera: Culicidae) [PDF]

, 2008
One important step for the colonization of Ochlerotatus albifasciatus (Macquart) is to determine the optimal conditions for larval rearing, which makes possible the development of experiments comprising larval rearing in the laboratory.

Feeding spectra and activity of the freshwater crab Trichodactylus kensleyi (Decapoda: Brachyura: Trichodactylidae) at La Plata basin [PDF]

, 2014
Background: In inland water systems, it is important to characterize the trophic links in order to identify the ‘trophic species’ and, from the studies of functional diversity, understand the dynamics of matter and energy in these environments.

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.
