New Paper in Molecular Ecology

Our new paper on winter social structure in golden-crowned sparrows (Dai is a co-author) is now out at Molecular Ecology!
Arnberg et al. (2015) investigated the effect of kinship on social network structure in a wintering population of migrant sparrows across years. Our previous work (Shizuka et al. 2014) showed how these networks consist of social communities of birds that flock together with each other much more often than with others, and that these social communities remain stable across years (with turnover in membership). The current work shows that flocks are not composed of kin, although there are some high-relatedness pairs (equivalent to cousins) in the population. Our works shows how to integrate social network data with kinship data. This was also the first chapter in Nina Arnberg's (Lyon Lab, UCSC) recently-defended dissertation. Congrats Nina!
