The evolutionary dynamics of laying date in the pied flycatcher Ficedula hypoleuca
(2021-12-17)
Current global warming is unequivocally impacting biodiversity at an unprecedent rates. Such negative impact can be quantified on species distribution and diversity, but understanding biodiversity loss can only be fully ...
