A new paper led by (now graduated!) Ph.D. student Zoë Kitchel is now out in PLOS Climate. Using data from all around the world thanks to the FISHGLOB international consortium of researchers, she shows that marine fish communities are not homogenizing the same way that many communities on land are. Instead, she shows that many are differentiating through time, and others cycle between more homogenized and differentiated states. This is one of the first times that timeseries like this have been available. Fishing pressure and temperature helped explain these dynamics.
Paper alert: Marine fish communities cycle between homogenized and differentiated states through time
