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 ...

Plant diversification impact on the oviposition response of a predatory bug in a laboratory set‐up

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 128-134, February 2026.
Orius majusculus laid nearly twice as many eggs in cages with two different crop species compared with a single species. Depending on crop species, O. majusculus utilised different plant structures for oviposition. Crop diversification supports reproduction, and thus, is likely to have a positive effect on O.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

FEBS Letters, Volume 600, Issue 2, Page 164-187, January 2026.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Patterns and Driving Mechanisms of β‐Diversity in Mountain Plant Communities of Arid Regions

Ecology and Evolution, Volume 16, Issue 1, January 2026.
We analyzed taxonomic and phylogenetic β‐diversity patterns in plant communities along the northern slope of the central Kunlun Mountains in arid northwestern China. Species turnover dominated β‐diversity, with climatic distance—particularly temperature—being key drivers.

The Response of Krascheninnikovia ceratoides (L.) Gueldenst. to Environmental Changes Since the Mid‐Holocene in the Tibetan Antelope Breeding Ground of the Western Kunlun Mountains

Ecology and Evolution, Volume 16, Issue 1, January 2026.
We analyzed changes in the suitable habitat of K.ceratoides, which is the main food source of Tibetan antelopes, within the Tibetan antelope breeding grounds in the Western Kunlun Mountains. The study covered the period from the Mid‐Holocene to future projections and also examined the driving factors and shifting directions of the suitable habitat ...
