Blue light attracts nocturnally migrating birds

Xuebing Zhao, Min Zhang, Xianli Che & Fasheng Zou
Light pollution is increasing and artificial light sources have great impacts on animals. For migrating birds, collisions caused by artificial light pollution are a significant source of mortality. Laboratory studies have demonstrated that birds have different visual sensitivities to different colors of light, but few field experiments have compared birds’ responses to light of different wavelengths. We used three monochromatic lights (red, green, and blue) and polychromatic yellow light to study the impact of wavelength...

Using machine learning models to predict the distribution of a cryptic marine species: the sperm whale

Philippine Chambault, Sabrina Fossette, Mads Peter Heide-Jørgensen & Daniel Jouannet
Implementation of effective conservation planning relies on a robust understanding of the spatio-temporal distribution of the target species. In the marine realm, this is even more challenging for cryptic species with extreme diving behaviour like the sperm whales. Our study aims at investigating the movements and predicting suitable habitat maps for this species in the Mascarene Archipelago in the South-West Indian Ocean. Using 21 satellite tracks of sperm whale and 8 environmental predictors, 14 supervised...

Hunters versus Hunted: New perspectives on the physiological costs of survival at the top of the food chain

Terrie Williams, Mads Peter Heide-Jørgensen, Anthony Pagano & Caleb Bryce
Global biotic and abiotic threats,particularly from pervasive human activities, are progressively pushing large, apex carnivorous mammals into the functional role of mesopredator. Hunters are now becoming the hunted. Despite marked impacts on these animals and the ecosystems in which they live, little is known about the physiological repercussions of this role downgrading from ultimate to penultimate predator. Here we examine how such ecological role reversals alter the physiological processes associated with energy expenditure, and ultimately...
