| 1 | Predictors of dominance rank and agonistic interactions in captive Livingstone's fruit bats显示文摘Male dominance hierarchies have been studied in many animals but rarely in bats(Chiroptera).The dominance rank of social animals may dictate access to resources and mates;therefore,it has important implications for an individual's fitness and is crucial for successful captive man-agement.Between January and December 2018,at both Bristoi Zoo Gardens(Bristol,UK)and Jersey Zoo(Jersey,British Isles),we observed 19 male Livingstone's fruit bats Pteropus livingstonii using focal follows for 345 h overall,noting the outcome of all agonistic interactions.We recorded instigators of interactions,along with winners and losers,and analyzed these data using the R-package'EloRating'to create Elo-rating temporal plots of dominance ranks.We used generalized linear mixed models and multiple linear regression to analyze interaction data and test hypotheses regarding predictors of dominance rank,frequency of agonistic interaction,and choice of interaction partner.Age was positively correlated with dominance rank up to around year 9,when an asymptote was attained.Highly ranked bats instigated the most agonistic interac-tions,and largely directed these interactions at bats with much lower rankings than themselves.Hierarchies were extremely stable throughout the data collection period at both sites.We conclude that Livingstone's fruit bats have a stable linear dominance hierarchy,with high-ranking,typ-ically older males instigating the most interactions with lowest ranking males to secure dominance rank.This study adds to the limited discourse on Pteropus social behaviors,indicating that some bat species may have social systems similar in complexity to some nonhuman primates. | Sarah Richdon Eluned Price Dominic Wormell Gareth Jones Grainne McCabe | 2023 | Current Zoology2023，69，6： | 0 |
