Crustacean zooplankton species richness in Chilean lakes and ponds (23°-51°S)

open access: yesLatin American Journal of Aquatic Research, 2013
Chilean inland-water ecosystems are characterized by their low species-level biodiversity. This study analyses available data on surface area, maximum depth, conductivity, chlorophyll-α concentration, and zooplankton crustacean species number in lakes ...

Spatial Structure Explains Morphological Variation Better Than Climatic Gradients in the South American Rattlesnake (Crotalus durissus)

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...

Synopsis of the genus Empicoris (Hemiptera: Heteroptera: Reduviidae) in Chile [PDF]

open access: yes, 2011
The species of Empicoris Wolff, 1811 recorded from Chile are listed, and an identification key for all four species is provided. New distributional records from Chile are added: E. errabundus (Say, 1832) and E.

Ciliados (Protozoa) de sedimentos secos de una charca temporaria de la Argentina [PDF]

open access: yes, 2009
Temporary ponds represent special environments that are inhabited by organisms adapted to changing environmental conditions. Ciliates are able to survive complete loss of water in these transient habitats through cyst formation. Nevertheless, ciliates

Mammal defaunation leads to biotic homogenization of plant communities in tropical rainforests

open access: yesEcology, Volume 107, Issue 3, March 2026.
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.

Limno‐STOICH: A comprehensive database linking the elemental stoichiometry of organisms with inland aquatic habitats

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract All organisms contain carbon, nitrogen, and phosphorus in widely ranging amounts and proportions. Integrating existing datasets enables quantification of this variation at global scales. Such efforts could leverage ecological stoichiometry theory, the study of elemental supply and imbalances in ecological interactions, to connect ecological ...

Patch and Landscape Predictors of Mammal Diversity and Their Trait‐Relationships in the Largest Atlantic Forest Island in Brazil

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...

Limnological investigation in Tierra del Fuego, Argentina

open access: yesBiología Acuática, 2019
Lentic environments belonging to Isla Grande of Tierra del Fuego stand as a field of particular, limnological interest. Some of the reasons for this are their austral location, the scarce influence they have received from man's action and the lack of ...
