Extra-pair paternity in birds - an evolutionary perspective ------------------------------------------------------------ Trial lecture by Terje Lislevand Tid: ONSDAG 14.05 kl. 10.15-11.00 Sted: Auditorium 4, Realfagbygget Abstract: Recent molecular studies of paternity patterns in many bird species have shown that females frequently mate with partners outside the social pair bond. In others, females remain faithful to their social mates. In this lecture, I present some hypotheses explaining the variation in rates of extra-pair paternity in birds, within and between species. I also present some results from case studies illustrating the diversity of avian genetic mating systems. En populær fremstilling av foredraget ble publisert i BT 11.05.2003:
