(a) European river invertebrate communities showed an average increase in local richness over time (1994–2023), indicating partial local recovery following the alleviation of anthropogenic stress (e.g., point‐source pollution). However, this local recovery was not accompanied by increases in β‐diversity, likely due to persistent, unaddressed stressors,

Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...

CALIDAD DE NARANJA ‘VALENCIA’ DURANTE EL ALMACENAMIENTO A BAJA TEMPERATURA
The quality of non waxed (control) and waxed ‘Valencia’ oranges was evaluated during a storage at 2 °C and 6 °C, and after marketing conditions (20 °C for six days). Every week during the cold storage, the fruits were evaluated for: Maturity index (total soluble solids/titratable acidity), color (a/b ratio), weight loss, chilling injury (CI), and decay.

Plant Responses to Anomalous Heat and Drought Events in the Sonoran Desert
What are the impacts of region‐wide heat and drought events on desert vegetation? This multi‐scale assessment shows that columnar cacti and succulent trees show acute plant stress across the Sonoran Desert. The expected increased frequency of heat and drought events will likely have landscape‐wide impacts that could fundamentally reshape populations of

Abstract Citizen science data are increasingly used for ecological research, biodiversity conservation and monitoring. However, these data often present significant analytical challenges due to uneven recording efforts by citizen scientists. Biases caused by intra‐annual differences in levels of recording activity can be particularly severe, hindering ...
