Dear colleagues,
this week's Biology Thurdsay seminar, 25th March, 12:15 (zoom link below) will be given by
Dr. Maria Hällfors, University of Helsinki, Research Centre for Ecological change, on
Species responses to climate change: range shifts, phenology shifts, and adaptational lag.
Biodiversity is threatened by a multitude of anthropogenic factors, including ongoing climate change. Under environmental change, species can adapt in situ through plastic or evolutionary responses, move to areas where conditions are more favourable, or if they are unable to respond in either way, they decline and eventually go extinct. In my talk, I will give examples of all three alternative pathways: bird species responding by advancing their breeding phenology, albeit with an non-uniform pattern across the season; Lepidoptera for which range shifts are more common than shifts in phenology; and a plant species that shows adaptational lag as it has not been able to respond to the changes that have occurred to date.
