From maps to mandates: Multitemporal vegetation cover analysis as a tool to evaluate environmental judicial decisions

People and Nature, Volume 8, Issue 4, Page 886-903, April 2026.
Abstract This study examines the use of multitemporal vegetation cover analysis as a tool to assess the ecological effectiveness of judicial decisions that recognize the rights of nature, using Colombia's 2016 T‐622 decision on the Atrato River as a case study.

Detecting Pteridium arachnoideum and Tithonia diversifolia in a Multiclass Land‐Cover Framework in the Cerrado: A Deep Learning Time‐Series Benchmark With Spatial Cross‐Validation

Transactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT This study presents the first deep‐learning time‐series benchmark for detecting two encroaching species in the Brazilian Cerrado: the native super‐dominant fern Pteridium arachnoideum and the invasive alien shrub Tithonia diversifolia. We evaluate 43 architectures across six families (CNNs, RNNs, Transformers, and three hybrid groups) on ...

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

Ecology 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 ...

Beyond Ecology: How Environmental and Social Landscapes Shape Tropical Forest Restoration in Southeast Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Restoration was more associated with environmental variables than socioeconomics. Active restoration was utilized in degraded areas and pasture abandonment favored natural regeneration. Successful tropical restoration is dependent on a complex interdependent mix of factors.

Shifting in the shadows: Morphofunctional variations of Miconia sellowiana Naudin (Melastomataceae) associated with cave environments

Plant Biology, Volume 28, Issue 2, Page 441-451, March 2026.
Cave environments filter plant traits, selecting thinner, smaller leaves with reduced photosynthetic and vascular structures. Abstract Caves present unique ecological conditions that influence the distribution and adaptation of species, yet studies on cave‐associated vegetation remain limited.
