在突尼斯中部的Bou Hedma国家公园的8个生境中研究了Isabelline serhalinus的季节性活动。从2010年6月到2011年6月，实施了雾网和回声定位呼叫记录两种技术。这种蝙蝠全年都有捕获，但只在水体中捕获，特别是在努赫盆地。捕获量在春末夏初达到顶峰，在冬季下降。四月至六月捕获怀孕雌蚊，五月至六月捕获哺乳期雌蚊。回声定位呼叫全年都有记录，但不是每个月都有。据报道，大多数活动发生在水体和路灯处。活动在春末秋初达到高峰，在冬季下降。终末蜂鸣声主要分布在流域，在春末夏初和初秋达到高峰。我们的研究对水体的重要性提供了进一步的见解，在国家公园和整个国家的管理计划中应该引起特别的重视。
The seasonal activity of the Isabelline serotine bat Eptesicus isabellinus was studied in eight habitats of the Bou Hedma National Park, central Tunisia. From June 2010 to June 2011 two techniques, mist-netting and echolocation call recording, were implemented. This bat species was captured throughout the year but only at water bodies and particularly at Nouh basin. Captures peaked in late spring-early summer, and declined in winter. Pregnant females were captured from April to June, and lactating females in May and June. Echolocation calls were recorded throughout the year, but not every month in all habitats. Most activity was reported at water bodies and street lamps. Activity peaked in late spring and early autumn, and declined during winter period. Terminal buzzes were mainly detected at basins, peaking in late spring-early summer and early autumn. Our study provided further insights on the importance of water bodies which should draw particular attention in the management plan of the national park and in the whole country.
