Marjorie Sorensen and her international team of collaborators have just published a paper in Ecology and Evolution asking whether longer bird migrations are associated with increased blood parasitism, by exposing birds to a greater variety of parasites. Marjorie and team used stable isotopes to estimate the migration distances of willow warblers wintering in Zambia, and found that this was unrelated to blood parasitism or other indices of health and condition, suggesting that other factors might be more important in determining individual susceptibility to disease in migratory birds.
Tanmay Dixit was a member of a team organising and lecturing in the inaugural Evolutionary Biology Crash Course. This course, aimed at undergraduate or early-postgraduate students, teaches evolutionary principles to students who have had limited opportunities to be exposed to evolutionary ideas. The course is funded by the Equal Opportunities Initiative Fund of the European Society of Evolutionary Biology (ESEB). Tanmay presented lectures on behavioural ecology and evolution, focussing on kin selection, coevolution, and parasitism. Over 700 students, with the vast majority from the global South, attended the course, which was a resounding success!
