“…Predators may be attracted to roosts with a large number of individuals due to increased noise or scent associated with large aggregations and switching roosts frequently may prevent predators from keying in on a particular roost (Barclay et al, 1982;Fenton et al, 1994;Ruczyński and Bogdanowicz, 2005). However, roost fidelity does not differ between males and females in all Rafinesque's big-eared bat populations (Trousdale et al, 2008;Johnson et al, 2012). In Mississippi, where natural roosts are scarce, adult male and female Rafinesque's big-eared bats do not differ in their roost fidelity or the number of roosts used (Trousdale et al, 2008).…”

“…Within the Coastal Plains, big-eared bats are associated with bottomland hardwood forests for both foraging and roosting (Clark, 1990;Trousdale and Beckett, 2005;Johnson and Lacki, 2013); females form maternity colonies in the spring and summer while males remain solitary for most of the year (Jones, 1977). Like most forest bats, big-eared bats frequently switch roosts (Trousdale and Beckett, 2005;Trousdale et al, 2008;Johnson et al, 2012) but frequency of roost switching and the number of roosts per bat or colony has received little study.…”

“…Long-tailed bats have been noted roosting in both dead P. radiata (Daniel 1981;G Newton, contractor Rates of roost re-use are low for long-tailed bats in agricultural landscapes and native forests (Sedgeley & O'Donnell 1999b), but appear higher in areas where fewer roosts were located during research (Alexander 2001;Dekrout 2009). The same is true of other species, including Rafinesque's big-eared bat (Corynorhinus rafinesquii [Trousdale et al 2008]) and the tent-making bat (Artibeus watsoni [Chaverri et al 2007]). In southern New Zealand Nothofagus forest, only 10.1% of the 79 roosts located by radiotracking during a 5-month summer period were re-used (O'Donnell & Sedgeley 1999).…”

Environmental certification schemes have stimulated increasing interest in biodiversity and its management within exotic plantation forests. These schemes expect management to be scientifically-based, even though little is known about how often, or which, native species use exotic plantation forests. Greater knowledge of the ecology of native species within exotic plantation forests is required to advise management and reduce risks to native species, particularly those that are rare, such as the New Zealand long-tailed bat (Chalinolobus tuberculatus). Long-tailed bats use exotic plantation forests throughout New Zealand but need protection from the impacts of forest management, and particularly clear-fell harvest, that is achievable only through a better understanding of their biology. The consequences of the current reduced re-planting, and the conversion of plantation forests into pasture resulting in smaller forested areas, should not be ignored because they may be associated with reductions in longtailed bat populations. We review the current knowledge of long-tailed bats' use of exotic plantation forests, and report for the first time which exotic plantations long-tailed bats are known to use. We make recommendations for the design of monitoring programmes to detect long-tailed bats within plantation forests, and for research into the effects of forest management, especially logging, and comment on the likely impacts of reductions in forested areas on longtailed bats.

“…Similarly, in Noxubee National Wildlife Refuge, Rafinesque's big-eared bats used a wide variety of roost tree species including black tupelo (40%), American sycamore (10%), American beech (20%), sweetgum (20%), and swamp chestnut oak (10%- Fleming et al 2013a). DeSoto National Forest has a long history of intensive land use including logging, replacement of native forests by loblolly pine (Pinus taeda) plantations, and fire suppression (Trousdale et al 2008). Prior to the 1930s when it became a refuge, considerable logging occurred in upland and bottomland habitats in Noxubee National Wildlife Refuge (U.S.…”

“…However, there is considerable variation in sizes of trees used by Rafinesque's big-eared bats across study sites, with mean diameters ranging from 79 to 155 cm, almost a 100% difference (Trousdale 2011). The cause of variation in roost use is not known, but variation in roost fidelity and network structure by Rafinesque's big-eared bats was attributed to variation in roost availability (Trousdale et al 2008;Johnson et al 2012). The effects of roost availability and management history on use and selection of roosts have not been examined in Rafinesque's bigeared bats, but have been shown to be of value in other species (Miles et al 2006;Ruczyński et al 2010;Russo et al 2010;Borkin et al 2011).…”

Adaptive response to land-use history and roost selection by Rafinesque’s big-eared bats

Although habitat loss and degradation are major contributors to species declines, some species are able to adapt to changes in land use by selecting different habitats or structures in disturbed areas than they do in more pristine habitats. Bats are particularly vulnerable to changes in land use due to their dependence on specific habitat types and structures. The objective of this study was to determine how selection and use of roost trees, and niche breadth of Rafinesque's big-eared bats (Corynorhinus rafinesquii) varied with land-use history. I examined use and selection of roosts at 3 bottomland hardwood sites that varied in amount and time since timber harvest. Fortynine transects were established as a means of searching for bats in trees with basal cavity openings and were surveyed 2-9 times. Bats at the most-disturbed sites exhibited the broadest niches, using a greater number of tree species and habitat types, although bats at the least-disturbed site used a broader range of cavity volumes. Cavity characteristics were the primary factors governing roost selection by Rafinesque's big-eared bats, but selection varied among sites. Probability of use increased with increasing cavity volume for bats at all sites, but bats at the most-disturbed site primarily used trees in the smallest cavity volume class, whereas bats at the least-disturbed site primarily used trees in the largest cavity volume class. Results of this study suggest that Rafinesque's bigeared bats can adapt to a range of habitat conditions if trees with large cavities are available. However, future studies need to determine the long-term viability of this species in disturbed habitats.
