In an article published in PeerJ Peter Graystock shows how it is likely that the use of managed bees comes at a cost of increased parasites in wild bumblebees, which is not only a concern for bumblebee conservation, but which may impact other pollinators as well.

Research Published! A Novel Method of Assessing Dominance Hierarchies Shows Nuance, Linearity and Stability in the Dinosaur Ant Dinoponera quadriceps
Daniel P. Grainger, Claire L. Asher, Julia C. Jones, Fabio S. Nascimento, Seirian Sumner and William O. H. Hughes Many social species with relatively simple societies have dominance hierarchies of individuals, with dominant individuals achieving fitness and subordinate individuals either queuing to obtain fitness or achieving only indirect fitness by helping relatives. Assessing the dominance hierarchy in a social group is generally based upon observing dyadic interactions as and when they occur spontaneously within the whole-group setting. However, this
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
