How Social Structure Drives the Population Dynamics of the Common Vampire Bat (Desmodus rotundus, Phyllostomidae)

Abstract: Social systems are major drivers of population structure and gene flow, with important effects on dynamics and dispersal of associated populations of parasites. Among bats, the common vampire bat (Desmodus rotundus) has likely one of the most complex social structures. Using autosomal and mitochondrial markers on vampires from Mexico, French Guiana, and North Brazil, from both roosting and foraging areas, we observed an isolation by distance at the wider scale and lower but significant differentiation between … Show more

“…More years of serological data are needed to confirm such patterns, but one explanation for this inverse relationship could be bat movement that causes traveling waves of virus transmission (Bjørnstad et al, 1999). Our microsatellite data suggest historic panmixia of bats in this region of Belize, consistent with low population structure at small spatial scales in Mexico, Peru, and French Guiana, as also inferred using nuclear markers (Romero-Nava et al, 2014;Huguin et al, 2018). Additionally, mark-recapture detected rare but contemporary annual movement between sites, an 8 km distance relative to mean home ranges of 2-3 km (Burns and Crespo, 1975;Trajano, 1996).…”

“…Additionally, use of mitochondrial markers could also help illuminate how sex-dependent behavior shapes virus transmission (Streicker et al, 2016;Huguin et al, 2018). More broadly, however, our results suggest that the degree of connectivity found here likely enables virus persistence through inter-site contacts but is not sufficient to synchronize infection dynamics across sites (Blackwood et al, 2013).…”

“…The clearest example of kin-biased helping in bats is regurgitated food sharing in vampire bats [17]. Common vampire bats show preferred co-roosting associations with both kin and nonkin (mean within-roost relatedness = 0.08 [18, 19]). Yearling males disperse whereas females are typically philopatric and form long-term cooperative relationships within and between matrilines [17, 20].…”
