Molecular Responses to Climate Change: How Warming and Acidification Reshape the Proteome and Phosphoproteome of the Endangered Mira Chub

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
ABSTRACT Global environmental change affects organisms, including their physiology. In freshwater ecosystems, where migration is limited, populations often rely on phenotypic plasticity to respond. While transcriptomics has been widely used to study stress responses at the molecular level, less is known about the proteome, which reflects post ...

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 ...

Biosolid as an alternative source of nutrients in chrysanthemum cultivation

open access: yesScientific Reports
The objective was to evaluate the biosolids as an alternative source of nutrients in the production of chrysanthemums by adding increasing doses to the cultivation substrate. The experimental design was in blocks with 6 treatments and 5 replications. The

Abundance and Seasonal Dynamics of Guiana Dolphins (Sotalia guianensis) in Southern Brazilian Estuarine and Adjacent Coastal Waters

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Estimating population parameters is crucial for understanding species dynamics and assessing anthropogenic impacts, thereby supporting conservation efforts. We evaluate key population parameters—group structure, abundance and capture–recapture probabilities—of the Guiana dolphin in the Paranaguá Estuarine Complex and adjacent coastal waters ...

Linguagem natural e música em Rousseau: a busca da expressividade Natural language and music in Rousseau: the quest for expressiveness

open access: yesTrans/Form/Ação, 2008
As análises de Rousseau indicam que o ingresso no universo simbólico traz consigo a possibilidade da perda da unidade do indivíduo e com ela a possibilidade de ruptura do vínculo social.

The Role of Elevation, Connectivity and Land Cover on Migratory and Non‐Migratory Fish Communities in an Amazonian Riverine System

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Dams and deforestation are key drivers of freshwater biodiversity loss in the Amazon, as they alter river connectivity, water quality and habitat structure. This study investigates how connectivity (Reach Connectivity Index—RCI), elevation and natural land cover influence the diversity and composition of fish assemblages in a highly fragmented

Platão e o pensamento grego

open access: yesTrans/Form/Ação, 1982
O Pensamento de Platão tem o encanto das estátuas de Dédalo: esvai-se pelos meandros do discurso, tão logo se pretenda travar com ele uma relação de domínio.

Recommendations for Improving the Modeling of Wintering Waterbird Population Sizes and Trends

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We assessed four statistical approaches (simple GLMM, optimized GLMM, LORI, and TRIM) for analyzing International Waterbird Census data and found that commonly used methods inadequately address zero inflation, overdispersion, and spatial autocorrelation.
