The research (which represents a collaboration between UCC, ERI, the Marine Institute, QUB, UCD, University of Edinburgh, and University of Helsinki) uses quantitative genetics to explore a discordance between observed and predicted rates in the evolution of body size in female salmon from the Burrishoole catchment in Co. Mayo. “The monitoring of Atlantic salmon at Burrishoole provides researchers with an incredible source. It is only with such long-term studies that we are able to observe the inter-generational evolutionary dynamics of species”, said Mr. O’Sullivan.

The research is published in Ecology and Evolution and is Open Access: O'Sullivan et al 2019.

Congratulations to our colleague Ronan O'Sullivan @uccBEES and co-authors on their publication. Check it out here:https://t.co/8NCcPDPk3e
