Wolves and humans both shape patterns of deer browsing in a temperate forest ecosystem of Central Europe

open access: yesEcography, EarlyView.
Predator–prey interactions can trigger behavioural responses in ungulates, influencing their space‐use and foraging behaviour and, in turn, indirectly affecting browsing pressure. Changes in browsing pressure can affect plant recruitment and species composition, shaping forest regeneration through predator‐mediated trophic cascades.

An Evaluation of Shock Waves in Unsaturated Wet Snow [PDF]

open access: yesAnnals of Glaciology, 1983
The propagation of shock waves in unsaturated wet snow is investigated, both analytically and experimentally. The experimental program was carried out in the laboratory with an electromagnetic stress-wave generator. During each test, impact velocity was measured at the base of the specimen by means of a contacting wire system.

Civil Society Advocacy and Climate Change in Kenya: The Question of “Local Voices” and Their “Amplification”

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The role of civil society organizations (CSOs) in addressing climate change is acknowledged, but engagement with questions of voice remains limited, especially in the Global South. Addressing this, this paper zooms in on (International) nongovernmental organizations ((I)NGOs) and their collaborations with domestic CSOs in the Global South on ...

Comprehensive Review on Advancements in Food Preservation Technologies for Quality and Sustainability

open access: yesFood Chemistry International, EarlyView.
Preservatives limit microbial development, oxidation, and enzymatic degradation, resulting in better food quality and extended shelf life. Classified as natural, synthetic, or biological, each preservative has distinctive attributes and modes of action. Growing preference for natural preservatives aligns with clean label trends.

TerraSAR-X Time Series Fill a Gap in Spaceborne Snowmelt Monitoring of Small Arctic Catchments—A Case Study on Qikiqtaruk (Herschel Island), Canada

open access: yesRemote Sensing, 2018
The timing of snowmelt is an important turning point in the seasonal cycle of small Arctic catchments. The TerraSAR-X (TSX) satellite mission is a synthetic aperture radar system (SAR) with high potential to measure the high spatiotemporal variability of

Independent leaf and root responses to autumn freezing in perennial herbs: Insights from cutting and transplant manipulations

open access: yesGrassland Research, EarlyView.
In this study, we compared two sampling approaches to assess autumn freezing resistance. Our goal was to determine whether the commonly employed cutting method, which disrupts root‐tissue connectivity, provides a valid measure of true freezing resistance.

Evapotranspiration Estimation and Irrigation Performance Assessment Using Remote Sensing: A Case Study of the Ergani Dam Irrigation System (Turkey)

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Efficient water resource management is critical for sustainable agriculture, with evapotranspiration (ET) serving as a key parameter. Remote sensing (RS) techniques offer cost‐effective approaches for ET estimation and irrigation performance assessment in extensive agricultural systems.

Monitoring Snowmelt in Mountainous Areas by Considering SAR Geometric Distortion From Ascending and Descending Orbits

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Synthetic aperture radar (SAR) multitemporal and multipolarization change detection method has been widely utilized for wet snow extraction. Although SAR terrain correction can alleviate the geometric distortion caused by foreshortening and layover, it ...

Bias Correction of ERA5 Temperature Across Five Topoclimatic Clusters: A Comparative Evaluation of Four Methods

open access: yesInternational Journal of Climatology, EarlyView.
ERA5 near‐surface temperature over South America exhibits systematic cold biases in daily maximum temperature and warm biases in daily minimum temperature. To address the continent's strong climatic and topographic heterogeneity, South America was partitioned into five topoclimatic clusters, and four bias‐correction approaches were evaluated. The Multi‐
