Saharan striped polecats in agricultural landscapes use many burrows (30–35 per season), facilitated by sandy soils. Burrow sharing is rare and mainly occurs between males and females during mating. Habitat use shifts seasonally, reflecting disturbance and soil conditions. Maintaining stable sandy habitats may be critical for persistence.

Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...

Recovery of great blue herons (Ardea herodias) within the Chesapeake Bay
We surveyed great blue herons throughout the tidal reach of the Chesapeake Bay in 2013 and mapped 423 colonies supporting 15,094 pairs. The population has increased more than four‐fold since the mid‐1970s. Colony size has declined. Invasion of colonies by bald eagles may be driving a change in spatial structure.

Mapping Soil Salinity Prediction Enhanced by Time‐Series Remote Sensing Features
ABSTRACT Gaining timely knowledge of soil salinity's spatiotemporal dynamics is crucial for accurate mapping. Through temporal span comparisons, this study systematically extracts and utilizes time‐series features (TSFs) derived from Sentinel‐2 and Landsat 8 NDVI and SAVI data (2019–2023) to enhance prediction accuracy. Three datasets were constructed:
