Diet Switching and Interspecific Competition in Sympatric Steppe Ungulates Under Seasonal Resource Variability

Ecology and Evolution, Volume 16, Issue 2, February 2026.
ABSTRACT Understanding the mechanisms of competition and coexistence among sympatric species is crucial for deepening our understanding of interspecific interactions and informing the conservation of rare and endangered wildlife. In this study, we utilized DNA macro‐barcoding technology to analyze the seasonal dietary habits of Kiang (Equus kiang) and ...

Evolution and Climate Adaptation in Eurasian Gyrfalcon Populations

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This reports the influence of past, current and future Arctic climate change to the evolution of Eurasian gyrfalcons (Falco rusticolus), and reveals that its current evolutionary potential is insufficient to cope with the ongoing Arctic warming. ABSTRACT Climate change is considered a key driver for shaping ecological and evolutionary processes of ...

Sex‐Specific Phenotype‐Performance Links: Divergent Correlations Between Morphology, Coloration, and Bite Force in the Mountain Dragon (Diploderma vela)

Ecology and Evolution, Volume 16, Issue 2, February 2026.
D. vela exhibited pronounced sexual divergence in morphological traits, bite force, and body coloration, shaped by the interplay of three evolutionary mechanisms: sexual selection, fecundity advantage, and intraspecific niche divergence. These complementary, non‐exclusive processes collectively enhance adaptive fitness in the hot, dry river valley ...

Detecting and modeling topography‐induced differences in plant productivity across a grassland ecosystem gradient

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Understanding spatial variation in grassland productivity is critical for ecological modeling and management. The Great Plains of North America, a vast grassland region east of the Rocky Mountains, exhibits strong gradients in aboveground net primary production (ANPP) linked to precipitation and finer scale topoedaphic variation.

Branch Orientation: A Potential Indicator of Stem Rehydration and Water Stress

Hydrological Processes, Volume 40, Issue 2, February 2026.
Perceptual model illustrating how conifer branch position varies with tree water status. Well‐hydrated trees maintain branches in upward or horizontal positions due to higher water content and turgor pressure. As water stress increases, branches progressively droop downward.
