Abstract

In the current study, we investigate in greater detail the potential for among-population differentiation in climate use and preferences through the annual cycle. Our aims were to: (i) analyze variation in the realized climatic niche among the six genetically distinct populations of Cardellina pusilla, and (ii) determine whether the populations within the species have a specific niche-following or niche-switching migratory behavior, in order to understand how this could shape the migratory connectivity and population trends of each population.
