Research Published! Fine‐scale spatial genetic structure of common and declining bumble bees across an agricultural landscape

Stephanie Dreier, John W. Redhead, Ian A. Warren, Andrew F. G. Bourke, Matthew S. Heard, William C. Jordan, Seirian Sumner, Jinliang Wang and Claire Carvell   Land-use changes have threatened populations of many insect pollinators, including bumble bees. Patterns of dispersal and gene flow are key determinants of species’ ability to respond to land-use change, but have been little investigated at a fine scale (<10 km) in bumble bees. Using microsatellite markers, we determined the fine-scale spatial genetic structure of populations

Research Published! Extensive Local Gene Duplication and Functional Divergence among Paralogs in Atlantic Salmon

By Ian A. Warren, Kate L. Ciborowski, Elisa Casadei, David G. Hazlerigg, Sam Martin, William C. Jordan and Seirian Sumner. Many organisms can generate alternative phenotypes from the same genome, enabling individuals to exploit diverse and variable environments. A prevailing hypothesis is that such adaptation has been favored by gene duplication events, which generate redundant genomic material that may evolve divergent functions. Vertebrate examples of recent whole-genome duplications are sparse although one example is the salmonids, which have undergone a whole-genome
