Elements on the move: How ungulate migration expands Alpine biogeochemical footprints

Journal of Animal Ecology, EarlyView.
Using a spatially explicit model parameterized with GPS telemetry, we show that migratory and resident red deer play distinct roles in nitrogen redistribution across alpine landscapes. Migrants uniquely transport nitrogen upslope and up elevation, linking ecosystem element pools and revealing how the loss of migration alters large‐scale ecosystem ...

From LiDAR point clouds to 3D tree morphometrics: New approach to quantitatively evaluate tree shapes

Methods in Ecology and Evolution, EarlyView.
Abstract Tree crowns are complex, three‐dimensional structures whose morphology varies among species, individuals and environments. Although light detection and ranging (LiDAR) provides high‐resolution, single‐tree point clouds that advance species discrimination and the assessment of intraspecific variation in situ, crown shape is still commonly ...

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Downstream Passage Performance of European Silver Eels (Anguilla anguilla): The Importance of Phenotypic Variation and Rack Design

Animal Conservation, EarlyView.
During their spawning migration, European silver eels frequently encounter hydropower facilities where successful downstream passage is essential for the conservation of this critically endangered species. In this study, we evaluated how three angled rack designs and individual behavioral variation influenced downstream passage success in large‐scale ...
