Investigation of the dynamic changes in hibernating bat populations in the tunnels of an artificial canal in Jiyuan,Henan Province
摘要
Abstract
Hibernation plays a vital role in the reproductive success and sustainability of bat populations.Prior studies have recognized the artificial channel tunnels in Jiyuan,Henan,as important hibernation habitats for bats,with annual in-creases in hibernating populations and variations in hibernation patterns.Nonetheless,the extent of dynamic fluctuations in species composition and individual numbers of hibernating bats during hibernation remains uncertain.To address this,we conducted four surveys assessing the population dynamics of hibernating bats in this region from November 2023 to February 2024.Although historical data indicated a consistent upward trend in hibernating populations,our monitoring from 2023 to 2024 revealed no significant increase in the overall population.Notably,there was a shift in species compo-sition:Murina aurata was absent,while Rhinolophus episcopus was newly recorded.The proportion of bat numbers among different bat species showed minimal fluctuation,with R.nippon remaining the predominant species,followed by R.pusillus.The population demonstrated consistent fluctuations during the hibernation period,with overall numbers re-maining stable in November and December,peaking in January,and reaching their lowest point in February.Spatially,the proportion of hibernating individuals in areas with low-temperature fluctuations,located less than 30 meters from the cave entrance,decreased from a historical 20.0％to 7.8％.The hibernating population of R.pusillus demonstrated con-siderable variability,indicating a preference for warmer areas.Notably,the extreme cold wave events from December 2023 to February 2024 exacerbated microclimate fluctuations at the cave entrance,prompting spatial redistribution and adjustments in the population dynamics of hibernating bats.Our subsequent investigations revealed that numbers of hi-bernating bats undergo dynamic changes,with both population size and habitat selection during hibernation may be influ-enced by changes in external environmental conditions.These findings enhance the ecological understanding of bat hi-bernation in China and provide scientific evidence on the impact of extreme environmental conditions on hibernating bat populations.关键词
