A global consistent database of plankton and detritus from in situ imaging by the Underwater Vision Profiler 5

Plankton and detritus are essential components of the Earth's oceans influencing biogeochemical cycles and carbon sequestration. Climate change impacts their composition and fluxes, and marine ecosystems as a whole. To improve our understanding of these changes, standardized obse...

Cool‐Water Dolphins Have Larger Appendages Than Warm‐Water Dolphins

ABSTRACT Aim Endothermic marine mammals face significant thermoregulatory challenges due to heat loss in the highly conductive marine environment. Allen's rule states that endothermic animals in cold environments have smaller appendages than those in warmer environments. While bo...

Wild felids as sentinels of antimicrobial resistance: susceptible Escherichia coli isolates from a protected area in southeastern Brazil

Abstract Antimicrobial resistance (AMR) is a major global health concern, and its monitoring in wildlife is essential from a One Health perspective. Here, we obtained bacterial isolates and assessed the AMR profiles and extended-spectrum β-lactamase (ESBL) production of Escherich...

Early-life exposure to plastics is associated with health parameters and biomarkers in southern giant petrels

The sub-lethal effects of plastics and their associated chemicals on wildlife are poorly understood, primarily due to the lack of reliable indicators. We used southern giant petrels ( Macronectes giganteus, SGP), key scavengers and predators in southern seas, to assess whether ea...

Supercharged penguins—supplementary feeding reshapes tawaki/Fiordland penguin winter migration

Migration in a species is primarily a response to resource availability, shelter, thermoregulation, predator avoidance, or seasonal environmental change. Tawaki/Fiordland penguins ( Eudyptes pachyrhynchus ) have earned the nickname “marathon penguins” as they migrate 2,500 km fro...
