Kudos for Shirin Taheri who just published the first article from her PhD thesis in Global Change Biology.
We show that determinants of bird species range shifts in Great Britain, in the past decades, is likely driven by a combination of factors (climate change, land-cover change, and stochasticity) and that the strength of the signal of each one of these factors varies across the country. For example, rear edges of northerly distributed species seem to be strongly driven by climate change, whereas leading edge of southerly distributed species carry a stronger imprint of land cover change.
