Looking into the past – the reaction of three grouse species to climate change over the last million years using whole genome sequences
Abstract Tracking past population fluctuations can give insight into current levels of genetic variation present within species. Analysing population dynamics over larger timescales can be aligned to known climatic changes to determine the response of species to varying environments. Here, we applie...
