“…To our knowledge, as another nonmigratory bat species, T. pachypus does not follow the swarming site mating pattern, their mating events may occur mostly in bamboo internodes [26], [27]. Our previous parentage analyses on T. pachypus have demonstrated that related females preferred to mate with the specific individual males [26].…”

“…Mark-recapture data collected in natal localities of T. pachypus has revealed that the number of migration events between localities was very low (0.7%, for more details see Zhang et al 2011) [27], further indicating limited dispersal between localities. In this study, AMOVA analyses with microsatellite and mtDNA data demonstrated significant differentiation at two hierarchical levels: among roosting groups and among localities, separately.…”

“…Mark-recapture data from adult T. pachypus revealed a similar pattern of individual movements [27]; however, it is not yet clear whether these reflect recurrent fission-fusion events, or whether they are temporary movements related to mating events. Indeed extra-group copulations are strongly supported by our earlier parentage analyses of 54 roosting groups of T. pachypus in South China, in which offspring belonging to full sibships were often found to be sired by males not present in the group at the time of sampling.…”

“…Despite this varied group structure, group membership seems to be relative stable across seasons [25]. Recent studies on the lesser flat-headed bats using mark-recapture data suggested that the rate of natal dispersal was similar for male offspring (82.2%) and female offspring (66.7%, P >0.05), although males appeared to travel over longer distance (males, mean 787.5±SD 27 m; females 517.4±SD 25 m) [27].…”

Population genetic structure has important consequences in evolutionary processes and conservation genetics in animals. Fine-scale population genetic structure depends on the pattern of landscape, the permanent movement of individuals, and the dispersal of their genes during temporary mating events. The lesser flat-headed bat (Tylonycteris pachypus) is a nonmigratory Asian bat species that roosts in small groups within the internodes of bamboo stems and the habitats are fragmented. Our previous parentage analyses revealed considerable extra-group mating in this species. To assess the spatial limits and sex-biased nature of gene flow in the same population, we used 20 microsatellite loci and mtDNA sequencing of the ND2 gene to quantify genetic structure among 54 groups of adult flat-headed bats, at nine localities in South China. AMOVA and F ST estimates revealed significant genetic differentiation among localities. Alternatively, the pairwise F ST values among roosting groups appeared to be related to the incidence of associated extra-group breeding, suggesting the impact of mating events on fine-scale genetic structure. Global spatial autocorrelation analyses showed positive genetic correlation for up to 3 km, indicating the role of fragmented habitat and the specialized social organization as a barrier in the movement of individuals among bamboo forests. The male-biased dispersal pattern resulted in weaker spatial genetic structure between localities among males than among females, and fine-scale analyses supported that relatedness levels within internodes were higher among females than among males. Finally, only females were more related to their same sex roost mates than to individuals from neighbouring roosts, suggestive of natal philopatry in females.

“…Results of the sex odorant choice (SOC) experiment showed that both females and males had no difference in preference to the scent from bats of the same or opposite sex in the same group (Figure 5). As with other mammals, male bat offspring rarely mate within their natal group as they are usually chased away by the dominant male (Dobson, 1982; Greenwood, 1980; Moore & Ali, 1984), thus reducing inbreeding and increasing genetic diversity and survival advantage (Zhang et al, 2011). Another reason for this observation is that our sex choice experiment was performed in nonmating season, July to September, in which male bats ( Saccopteryx bilineata ) have been shown to lack male‐specific scent (Caspers et al, 2011).…”

Tylonycteris pachypus is a gregarious bat species with tens of individuals in a colony. The mechanisms by which mother bats recognize their pups and adult bats recognize each other are not clear. We hypothesized that such recognition is achieved by chemical discrimination and performed experiments to test the hypothesis. Results showed that mother bats were much more attracted to the scent from their own pups. For adult bats, females were attracted to the scent from both male and female groupmates but had a higher preference to the scent from female than from male groupmates. Male bats were much more attracted to the scent from male groupmates while showed no preference to the scent from female groupmates. Within a group, both female and male bats had no difference in preference to the scent from the same or opposite sex. These results suggest that mother–pup and groupmate recognition of T. pachypus can be achieved by olfactory cues.
