“…Most previous roosting studies have emphasized the importance of hardwoods for roosting by northern long-eared bats (e.g., Sasse and Pekins, 1996;Foster and Kurta, 1999;Menzel et al, 2002;Owen et al, 2002;Jackson, 2004;Carter and Feldhamer, 2005;Ford et al, 2006). However, in forests of New Brunswick that contained both deciduous and coniferous stands, female northern long-eared bats roosted primarily in hardwoods whereas males roosted mostly in conifers (primarily red spruce [Picea rubens]; Broders and Forbes, 2004).…”

“…Northern long-eared bats roost in cavities, crevices, and under exfoliating bark in deciduous hardwood trees; they are occasionally found roosting in conifers (Sasse and Pekins, 1996;Foster and Kurta, 1999;Lacki and Schwierjohann, 2001;Owen et al, 2002;Menzel et al, 2002;Jackson, 2004;Jung et al, 2004;Carter and Feldhamer, 2005;Ford et al, 2006). However, most previous studies of roosting by northern longeared bats were conducted in areas dominated by hardwood forests, and no comprehensive roosting studies have been conducted for this species in pine-dominated landscapes of the southeastern U.S.…”

“…Only recently has research begun to explore differences in roosting behavior between sexes and most previous studies of roost selection by northern long-eared bats either combined sexes (e.g., Lacki and Schwierjohann, 2001) or conducted the study on a single sex (e.g., Sasse and Pekins, 1996;Foster and Kurta, 1999;Menzel et al, 2002;Owen et al, 2002;Jackson, 2004;Carter and Feldhamer, 2005;Ford et al, 2006). Although Broders and Forbes (2004) differentiated roost selection between sexes, their study was conducted in New Brunswick and its applicability to ecosystems of the southeastern U.S. may be limited.…”

“…Although males have begun to receive attention during the past several years (e.g. Broders & Forbes 2004, Ford et al 2006, Perry et al 2007), few consistent patterns have emerged regarding the types of roosts or surrounding habitat used by male bats. Male bats are unlikely to form colonies during summer, although exceptions occur in certain species (e.g.…”

Appropriately, bat conservation in the USA during the 20th century focused on species that tend to aggregate in large numbers and locations (e.g. maternity roosts, hibernacula) where populations are most vulnerable. Extensive research into habitat needs (primarily for roosting) of reproductive females during the previous 2 decades has produced a wealth of information useful for developing conservation strategies for this group in their summer roost areas. However, the ecological needs of males, non-reproductive females, and juveniles have received far less attention, as have the ecological needs of all bats outside the pup-rearing season. Hence, it is unlikely that a single paradigm could comprehensively address conservation needs of all demographic groups within a species because they may have different seasonal distributions, reproductive strategies, and thermoregulatory needs. Herein, we recommend research into a wider spectrum of demographic groups and seasons to form a more holistic vision of the conservation needs of bats. We urge greater attention to understanding thermo-energetic and reproductive underpinnings of observed patterns of seasonal distribution and habitat selection by bats in the USA. Such understanding is instrumental for development of scientifically sound conservation strategies to confront emerging threats to conservation of bats in the 21st century: climate change, disease, habitat degradation, and environmental contaminants. We discuss interconnections among these emerging threats and the fundamental need to incorporate understanding of thermo-energetic strategies of bats in development of conservation strategies or legislation to mitigate potential impacts on bat populations of the USA.

Tree roosts of northern long‐eared bats following white‐nose syndrome

Spring emergence and summer maternity seasons are critical to long‐term survival of cave‐hibernating bats inhabiting geographic regions affected by white‐nose syndrome (WNS). White‐nose syndrome reached cave‐hibernating populations of bats in Mammoth Cave National Park (MCNP), Kentucky, USA, in 2013, with significant declines in several species of bats that hibernate in MCNP during winter 2014–2015, including the northern long‐eared bat (Myotis septentrionalis). To assess behavior and roost selection of individuals surviving to spring emergence and the summer maternity season, we radio‐tracked 26 northern long‐eared bats captured at various locations with differing habitat conditions in MCNP during 2015 and 2016. We tracked bats daily to identify roosting sites and patterns in use of roosts, describe habitat conditions associated with roosting sites, and quantify variation in size of colonies occupying roost trees. The average number of bats emerging from roost trees (3.58 ± 0.57 [SE]) was low compared with estimates for the species in studies completed pre‐WNS. Adult female bats selected trees within 6 roost areas with no overlap in use of roost areas between non‐reproductive females in spring and pregnant and lactating females in summer. Variation in roost tree and surrounding forest characteristics occurred across sex and reproductive condition classes, with males and pregnant and lactating females roosting at higher landscape positions than non‐reproductive females. Comparisons of roosting habitat models demonstrated the torpor model (decay class, stem diameter, canopy cover) to be parsimonious, regardless of sex and reproductive condition class, suggesting importance for choosing roost trees that facilitate use of daytime torpor. Such a strategy would promote energy savings and be consistent with behaviors anticipated for bats vulnerable to WNS effects during winter hibernation because these bats are potentially compromised in health and physiologic condition upon emergence from hibernation in spring. We encourage land managers responsible for roost trees of northern long‐eared bats to consider seasonal and landscape‐level variation in roosting habitat needs of these bats. © 2017 The Wildlife Society.
