Özet:
Threatened northern myotis (Myotis septentrionalis) and endangered Indiana myotis (Myotis sodalis) bat species populations are precipitously declining due to white-nose syndrome. Within the southeastern U.S., these imperiled bat species annually migrate to maternity areas on forested land managed with large-scale, frequent prescribed fire. Given the importance of survivorship and recruitment of remnant myotis populations, understanding how these bats respond to prescribed fire will facilitate better forest management. We examined roost site selection and foraging patterns of northern and Indiana myotis across fire intervals stands located within the Shoal Creek Ranger District of the Talladega National Forest in northeastern Alabama during the spring and summers of 2015--2017. Indiana myotis (n = 16) roosts were almost exclusively located in tall pine snags with less bark cover. Female (n = 43) and male (n = 17) northern myotis roosted in a wider variety of conditions, but more frequently selected snags. Northern (n = 11) and Indiana myotis (n = 4) foraged more in forest stands with prescribed fire than in stands with little or no prescribed fire. Northern myotis foraged mostly within intermediate prescribed fire stands (5.5--8 yr fire intervals), whereas Indiana myotis foraged in stands with frequent prescribed fire (0--3.5 and 3.5--5.5 yr fire intervals). These results suggest that northern and Indiana myotis are tolerant of prescribed fire on the landscape. Reasons for tolerance may be because prescribed fire increases insect diversity and reduces clutter, which may increase foraging efficiency. Furthermore, prescribed fire may increase suitable snag availability in areas with open canopies, allowing for increased solar exposure, which could increase neonatal development in maternity colonies.
