Spatiotemporal Variability of Seasonal Snow Cover over 25 Years in the Romanian Carpathians: Insights from a MODIS CGF-Based Approach

Remote Sensing
Understanding long-term snow cover dynamics is essential in mountain regions with limited meteorological or in situ observations. This study examines seasonal snow cover evolution across the Romanian Carpathians (2000–2025) using daily MODIS/Terra ...

Against the odds: Nesting specialization and foraging ecology provide insights into climate change responses in a mountain bee

Insect Conservation and Diversity, EarlyView.
A unique high‐elevation Exoneura bee defies typical elevation‐driven declines in bee activity, nesting exclusively in dead branches of snow gums near the alpine tree line. Nesting and foraging are tightly linked to snow gum presence, with most activity occurring within 30 m of these trees. Biophysical modelling indicates the bee's thermally constrained

Environmental and seasonal filtering of taxonomic, functional and phylogenetic diversity patterns of mountain butterflies in a prime butterfly area, Greece

Insect Conservation and Diversity, EarlyView.
Forest clearings support butterfly communities comparable to mountainous grasslands in alpha‐diversity and conservation value, yet remain compositionally distinct. Generalized linear models (GLMs) showed three key habitat predictors shaping multifaceted diversity and community composition: herb/grass height, flowerhead abundance and elevation.

First Detailed Record of Jikradia olitoria (Hemiptera: Cicadellidae) in the Swiss Southern Alps and Evaluation of Its Current Potential as a Vector of 16SrV‐Phytoplasmas

Journal of Applied Entomology, EarlyView.
ABSTRACT Jikradia olitoria Say is a Nearctic leafhopper that was recently reported in several European countries. Given its role as the vector of phytoplasmas associated with Grapevine Yellows diseases (GYD) in its native range, its presence in European vineyard agroecosystems could represent an important phytosanitary risk.

Early‐life temperature drives recruitment success in Eurasian perch (Perca fluviatilis) populations

Journal of Fish Biology, EarlyView.
Abstract Interannual fluctuations in the abundance of young‐of‐the‐year (YOY) European perch (Perca fluviatilis) were studied in two large French peri‐alpine lakes using a 12‐year dataset of late summer hydroacoustic surveys. Previous research has highlighted the importance of temperature.

Phenotypic plasticity is broadly adaptive across an elevation gradient in the Cutleaf Monkeyflower

New Phytologist, EarlyView.
Leaf shape plasticity expression is variable in Mimulus laciniatus. Summary Phenotypic plasticity is a key mechanism by which organisms cope with environmental heterogeneity, but its evolutionary consequences depend on how plastic responses align with the broader adaptive landscape.

Early‐Season Warming Advances Autumn Senescence in Temperate Tree Saplings in Association With Early Growth Dynamics

Plant, Cell &Environment, EarlyView.
ABSTRACT The timing of autumn leaf senescence is driven by external cues such as temperature and photoperiod and is strongly regulated by internal developmental processes. Correlative evidence suggests that earlier budburst and warmer conditions in spring and summer could accelerate development and advance senescence, yet this hypothesis remains ...

Phenology and carbon dioxide source/sink strength of a subalpine grassland in response to an exceptionally short snow season

Environmental Research Letters, 2013
Changes in snow cover depth and duration predicted by climate change scenarios are expected to strongly affect high-altitude ecosystem processes. This study investigates the effect of an exceptionally short snow season on the phenology and carbon dioxide

Bark‐associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes

Plant Biology, EarlyView.
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.

Room to regenerate: microhabitats and the recruitment niche as drivers of mountain woodland restoration

Restoration Ecology, EarlyView.
Abstract Introduction Natural regeneration is an efficient, minimal‐intervention approach essential for facilitating resilient, self‐sustaining ecosystems during woodland restoration. However, recruitment can be slow, uncertain, or highly restricted, particularly in mountain woodland systems where tree planting and large herbivore management are ...
