A Threat‐Scoring Framework Using Crowdsourced Data Indicates High Threat Levels in Fossorial Shieldtail Snakes

Animal Conservation, EarlyView.
Reliable estimates of species distributions are crucial for understanding their conservation needs. Yet for many species, IUCN largely relies on expert‐drawn ranges, which are often inaccurate. Focusing on shieldtail snakes in peninsular India, we combined citizen science, literature, field, and museum records to create improved distribution maps for ...

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, EarlyView.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Automating Archaeological Discovery: Assessing Geospatial Artificial Intelligence (GeoAI) Tools for Stone Wall Identification in Kweneng, South Africa

Archaeometry, EarlyView.
ABSTRACT The discovery of archaeological sites traditionally entails the utilisation of physically demanding exploration methodologies, including terrain surveying and the analysis of historical records. Recent technological developments have led to an increased use of non‐invasive remote sensing techniques, including Google Earth, LiDAR and aerial ...

GNET Derived Mass Balance and Glacial Isostatic Adjustment Constraints for Greenland

Geophysical Research Letters
Monitoring the Greenland mass balance (GMB) is crucial in the context of global sea level rise. Currently, three main methods are used to measure GMB, with the primary source of uncertainty arising from the glacial isostatic adjustment (GIA) contribution.
