Stage‐Specific Responses to Warming in Trojan Fir Across Early Life Stages: Germination, Seedling Survival, and Seedling Growth

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We investigated the effects of temperature, cold stratification, and light on germination and early seedling growth in Abies nordmanniana subsp. equi‐trojani (Trojan fir), an endangered endemic tree from northwestern Anatolia (Türkiye). Our results show that while higher fixed and alternating temperatures enhance germination, they also lead to ...

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

open access: yesEcology 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 ...

The new indices to describe temporal discontinuity of snow cover on the Qinghai-Tibet Plateau

open access: yesnpj Climate and Atmospheric Science
Snow cover on the Qinghai-Tibet Plateau significantly impacts the climate, hydrology, and ecology of China and East Asia. Current studies mainly use snow cover days to describe its duration, overlooking the snow’s discontinuous nature.

Phenology underlies inconsistent urbanization effects on avian malaria (Leucocytozoon sp.) in juvenile songbirds

open access: yesEcosphere, Volume 17, Issue 2, February 2026.
Abstract Urbanization can modify species interactions, including those between parasites and their hosts. In birds, urbanization can either increase or decrease avian malaria (haemosporidian) infection, depending on host species, parasite, or study location. However, temporal coordination between parasites and hosts, which may impact infection outcomes,

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

open access: yesHydrological 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.

Rain, Bark, and Residual Variability in Stemflow From Three Dominant Tree Species of a Southern Great Lakes Forest

open access: yesHydrological Processes, Volume 40, Issue 2, February 2026.
Terrestrial LiDAR and hydrology calibration were used to derive each tree's stemflow drainage area, normalising rainfall‐stemflow relations by contributing surface. The results show that Fagus grandifolia (beech) maintains a stronger, steeper hydrological response to rainfall (exhibited by a higher normalised yield) than Acer saccharum (maple) and ...

Psychotria caraballoensis (Rubiaceae), a new species from northern Luzon, Philippines

open access: yesNordic Journal of Botany, Volume 2026, Issue 2, February 2026.
In this paper, we describe and illustrate Psychotria caraballoensis, a new endemic species from the Caraballo Mountain Range, Luzon, Philippines. It is allied to the Subalpina species group sensu Sohmer and Davis (2007), and resembles Psychotria sohotonensis.

Divergent Transformation of Wet to Cold Bias on the Tibetan Plateau in Climate Models During Snow Season

open access: yesGeophysical Research Letters
Wet and cold biases on the Tibetan Plateau (TP) commonly exist in global and regional climate simulations. Previous studies have explored the possible causes of wet and cold biases and contributed to reducing these biases. However, the connection between
