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 ...

Finding patterns of distribution for freshwater phytoplankton, zooplankton and fish, by means of parsimony analysis of endemicity Encontrando patrones de distribución para fitoplancton, zooplancton y peces dulceacuícolas por medio de análisis de parsimonia de endemismos

open access: yesRevista Chilena de Historia Natural, 2008
During the last decades, limnological studies on Chilean systems have contributed to know the species composition and main environmental variables of many water bodies distributed over a wide latitudinal interval, from 18º to 53º S.

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.

Structure and density population of the invasive mollusc Limnoperna fortunei associated with Eichhornia crassipes in lakes of the Middle Paraná floodplain

open access: yesJournal of Limnology, 2015
The roots of Eichhornia crassipes provide different microhabitats for invertebrates, including substrate for the Asian invasive bivalve Limnoperna fortunei. This work evaluated the density and size structure of L. fortunei on the roots of E. crassipes in

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 ...

Climate change and El Niño Southern Oscillation influence on mixing regime and water quality in a deep tropical mountain lake

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Climate change alters lake functioning, water quality, and aquatic biota; yet our understanding of this process is poor for deep tropical mountain lakes. A 15‐yr dataset (2010–2024) from Lake Atitlán, Guatemala, revealed climate change impacts on a tropical lake ecosystem and showed a warming trend of 0.34 ± 0.14°C per decade that intensified ...
