Abstract

Abstract - Myotis austroriparius (Southeastern Myotis) traditionally inhabit bottomland hardwood forests along the Atlantic coastal plain and lower Mississippi River Valley. This insectivorous bat is a species of conservation concern in Alabama and Georgia and was thought to be restricted to the Southern Coastal Plain and Southeastern Plains ecoregions. Based primarily on cave, transportation-structure, and mist-netting surveys, we documented occurrences of Southeastern Myotis in 14 Alabama and 20 Georgia counties outside and along the border of the accepted range, including in the Piedmont, Ridge and Valley, Interior Plateau, and Southwestern Appalachians ecoregions. We reviewed observations of bats year-round in both states, including pregnant and lactating females and winter hibernacula. Roosting sites included caves, culverts, bridges, and tree cavities. Combined, these observations provide strong evidence that the range of Southeastern Myotis should consist of all Alabama and Georgia except for the Blue Ridge ecoregion. This increase in distribution may result from increased surveying efforts and/or range expansion due to climate change, as observed in other southeastern bat species.

阿拉巴马州和乔治亚州东南部肌炎的发生

摘要/ Abstract摘要:东南稻蛾(Myotis austroriparius)传统上栖息在大西洋沿岸平原和密西西比河下游的低洼阔叶林中。这种食虫蝙蝠是阿拉巴马州和佐治亚州的一种保护物种，被认为仅限于南部沿海平原和东南部平原生态区域。主要基于洞穴、运输结构和雾网调查，我们记录了东南Myotis在阿拉巴马州的14个县和佐治亚州的20个县的发生，包括在皮埃蒙特、山脊和山谷、内陆高原和阿巴拉契亚山脉西南部的生态区域。我们回顾了这两个州全年对蝙蝠的观察，包括怀孕和哺乳的雌性和冬季冬眠。栖息地点包括洞穴、涵洞、桥梁和树洞。综合起来，这些观察结果提供了强有力的证据，表明东南Myotis的范围应该包括整个阿拉巴马州和佐治亚州，除了蓝岭生态区。这种分布的增加可能是由于增加了调查工作和/或气候变化导致的范围扩大，正如在其他东南部蝙蝠物种中观察到的那样。

期刊介绍： The Southeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the southeastern portion of North America, roughly bounded from North Carolina south to Florida, west to Texas, north to Oklahoma, and east back to North Carolina. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion.
