Cool, cold or colder? Spatial segregation of prions and blue petrels is explained by differences in preferred sea surface temperatures
International audience The Southern Ocean provides one of the largest environmental gradients onEarth that lacks geographical barriers, and small but highly mobile petrelsliving theremay offer finemodels of evolution of diversity along environmentalgradients. Using geolocation devices,we investigate...
