  1. Using a common morphometric-based method to sex a migratory bird along its entire flyway despite geographical and temporal variations in body size and sexual size dimorphism

    Sexing bird species with monomorphic plumage is generally challenging, and sexual size dimorphism (SSD) is often used to develop morphometric-based sexing tools, e.g., using discriminant functions. Within species, local selection […]

  7. Gravity waves generated by the Hunga Tonga–Hunga Ha’apai volcanic eruption and their global propagation in the mesosphere/lower thermosphere observed by meteor radars and modeled with the High-Altitude general Mechanistic Circulation Model

    The Hunga Tonga–Hunga Ha′apai volcano erupted on 15 January 2022, launching Lamb waves and gravity waves into the atmosphere. In this study, we present results using 13 globally distributed meteor […]

  9. A new instrumental way to measure accumulating SWE in mountain and polar catchments directly, on the kilometre-scale and in near-real time

    The Snow Water Equivalent (SWE) of snowfall is important but difficult to measure. While numerous techniques have been developed, measurements are still too sparse, too poorly distributed, too infrequent, too […]

  11. Using telemetry data and the sea ice satellite record to identify vulnerabilities in critical moult habitat for emperor penguins in West Antarctica

    We tracked adult emperor penguins from Rothschild Island, west Antarctic Peninsula in 2015/2016 during a summer with extensive sea ice of long duration, contrasting with past years of reduced sea […]
