Consistent Trait Patterns in a Hyper Diverse Moth Clade Along a Western Himalayan Elevational Gradient

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study examines how Geometrid moth assemblages along a 1500‐m elevational gradient in the western Himalayas respond to temperature and air density shifts. While species diversity declines with elevation and turnover occurs from low to high elevations, no significant changes in morphological or flight traits were observed at the assemblage level ...

Natural resource inventories and management applications in the Great Basin [PDF]

open access: yes
ERTS-1 resolution capabilities and repetitive coverage have allowed the acquisition of several statewide inventories of natural resource features not previously completed or that could not be completed in any other way.

Mechanism of Dietary Variation of Grazing Yaks on Tibetan Plateau: The Role of Seasonal Heterogeneity of Resources

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Using DNA metabarcoding, we show that Tibetan yaks are highly selective foragers in the resource‐rich summer but switch to a diverse, generalist diet to survive the harsh winter. This flexible foraging strategy is driven by seasonal plant availability, providing strong support for optimal foraging theory and highlighting the critical need to protect ...

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

Changes in snow cover climatology and its elevation dependency over Romania (1961–2020)

open access: yesJournal of Hydrology: Regional Studies
Study Region: Romanian territory and the Carpathian Mountains, Romania.Study focus: We provide a consistent picture of long-term changes in relevant snow cover characteristics, including phenology (timing of the snow onset and melting), snow cover ...

First assessment of the plant phenology index (PPI) for estimating gross primary productivity in African semi-arid ecosystems

open access: yes, 2019
The importance of semi-arid ecosystems in the global carbon cycle as sinks for CO2 emissions has recently been highlighted. Africa is a carbon sink and nearly half its area comprises arid and semi-arid ecosystems.

Long‐Term Effects of Freeze–Thaw Events on Ecosystem Carbon Exchange

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
In this work, we utilized 24 long‐term (over 10 years) observed flux tower sites to analyze the impact of freeze–thaw events on net ecosystem carbon exchange (NEE) and ecosystem respiration (RE), and explored the resistance of ecosystem carbon exchange to freeze–thaw events.

Autumn snow expansion and spring divergence in Northeast China (2000–2020)

open access: yesAdvances in Climate Change Research
Mid-latitude snow has broadly declined, but Northeast China (NEC) shows a seasonal divergence that remains insufficiently explained. We integrated a cloud-free 500 m MODIS snow-phenology record with passive-microwave snow depth for 2000–2020 to map ...

Satellite‐Derived NDVI Predicts Forage Availability in a Wild Ungulate System: Ground‐Truthing Using Field‐Collected Vegetation Biomass

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This study uses three decades of field‐collected vegetation biomass data to ground‐truth satellite‐derived Normalised Difference Vegetation Index (NDVI) data from Landsat imagery as a proxy for resource availability for wild red deer on the Isle of Rum, Scotland.
