Babblers make the cover again!
Our paper on the impact of high temperatures on offspring survival to fledging and adult adjustment in provisioning behaviour, led by former PhD student (and now a graduated Doctor!) Amanda Bourne, has made the front cover of the November/December issue of Behavioural Ecology! This paper is part of a series of papers from Amanda Bourne's PhD on the pied babblers, regarding the potential impact of climate change on cooperative breeding animals. You can find references to all papers in the series in the publication list below. Follow this link to read the issue of Behavioural Ecology: academic.oup.com/beheco/issue/32/6 |
