| 中文摘要: |
| 本研究以栖息于废弃防空洞的雄性菲菊头蝠（Rhinolophus pusillus）作为研究对象，探究其夏季集群大小变化及其潜在影响因素。应用红外热成像仪监测菲菊头蝠在6月到8月期间的集群大小。利用单因素方差分析和一般线性回归模型，检验菲菊头蝠集群大小的月变化及其与洞内微气候的关系。研究发现，菲菊头蝠集群大小从6月至8月逐渐递增。集群大小变异系数6月高于7月和8月。菲菊头蝠集群大小与洞内温度和相对湿度均呈显著正相关关系。本研究表明，洞内微气候影响菲菊头蝠集群大小。这为野生蝙蝠栖息地保护与管理提供理论基础。 |
| 英文摘要: |
| Here, we used male Least Horseshoe Bats, Rhinolophus pusillus, to assess the change of colony size as well as the potential determinants throughout the summer. We used an infrared thermal imager to monitor the colony size of the bats inhabiting in a disused military fortification during June and August (Fig. 1). We applied one-factor analysis of variance (ANOVA) and the general linear regression model to test the monthly variation of colony size as well as to determinate relationship between bat colony size and microclimatic conditions in the cave. Analyses revealed that R. pusillus exhibited a marked increase in colony size from June to August (Fig. 2). The coefficient of variation in bat colony size was higher in June than that in July and August. The bat colony sizes were significant positive associations with ambient temperature, relative humidity in the cave (Fig. 3). These results highlight that microclimatic factors inside the cave affect the colony size of R. pusillus. Our findings provide a theoretical basis for roost conservation and management in wild bats. |
