Washington Post Highlights Prof. ter Hofstede's Study

Prof. ter Hofstede's paper "Sensory-based niche partitioning in a multiple predator - multiple prey community" was featured in the Washington Post.  The study published in the June 7, 2015 The Royal Society Proceedings B, looked at four species of gleaning bats and found that each species preferred different acoustic features in 12 prey species of katydids.  These findings may provide insight into the evolution of prey signal evolution.

Nature highlights research findings from Irwin Lab

Prof. Becky Irwin, Dr. Leif Richardson and other researchers in the Irwin Lab, have found that some compounds in floral nector reduce parasite loads in bees 60%-80%.  While the reduction in parasite load did not increase survival rates, these compounds could confer a benefit to bee colonies by reducing the spread of parasites.  These findings were highlighted in the February 26, 2015 issue of Nature.
