Gabriel has now defended his excellent PhD thesis on Matching Habitat Choice (qualified with the highest distinction; Sobresaliente Cum Laude). He used captive Zebra finches and wild Tree sparrows to test experimentally whether matching habitat choice can lead to reproductive isolation: see more here about his project. He also developed and employed new statistical models (quantitative genetic Animal Models) to test for the effects of matching habitat choice in wild populations. And the results are both exciting and worrying! (Download our paper in Methods in Ecology and Evolution – link).
