–Persistent human disturbance is a major cause for the decline in populations of many cave-dwelling bats and other sensitive cave-obligate organisms. Cave gating has been used to eliminate human disturbance, but few studies have assessed directly the impact of such management activities on resident bats. In northeastern Oklahoma, USA, 25 entrances of caves inhabited by two endangered species and one endangered subspecies of bats are protected from human entry with internal gates. Because cave… 
Gray Bat (Myotis grisescens)
TLDR
Cave protection is critical to the future recovery of this species, which is especially vulnerable to human activities in caves because they hibernate in dense clusters.
Impacts of Passage Manipulation on Cave Climate: Conservation Implications for Cave-Dwelling Bats
Abstract Human disturbance has caused declines in populations of many cave-dwelling bats and other cave-obligate organisms. Cave gating has been used to eliminate human disturbance, but few studies
Mixed effects of gating subterranean habitat on bats—A review
TLDR
Use of bat-compatible gates with horizontal bar spacing of 14.6 cm, bar types that offer high structural rigidity in areas where vandalism is likely, and periodic monitoring of gates to ensure they remain in good condition are recommended.
Conservation Ecology of Cave Bats
Caves and other subterranean sites such as mines are critical to the survival of hundreds of bat species worldwide, since they often provide shelter for most of a nation’s bat fauna. In the temperate
The effect of gates on cave entry by swarming bats
TLDR
The immediate effects of gates on the behaviour of swarming bats as they entered a natural cave are looked at and it is suggested that following the precautionary principle, the minimum spacing between horizontal bars in gates should be 150 mm.
An experimental test of gating derelict mines to conserve bat roost habitat in southeastern Australia
Abstract Management of derelict mines to improve subterranean bat habitat and minimise safety risks to the unsuspecting public is occurring more frequently. Many caves and mines around the world have
Population Connectivity of Endangered Ozark Big-Eared Bats (Corynorhinus townsendii ingens)
TLDR
It appears autumn swarming sites and winter hibernacula play an important role in providing opportunities for mating; therefore, protection of these sites, maternity caves, and surrounding habitat is suggested to facilitate gene flow among populations of Ozark big-eared bats.
Quantifying meso-mammal cave use in central Texas
Knowledge of meso-mammal cave use is essential for natural resource managers, particularly in the management of endangered cave invertebrates. Scat left by meso-mammals represents significant
Monitoring the Status of Gray Bats (Myotis grisescens) in Virginia, 2009–2014, and Potential Impacts of White-Nose Syndrome
Abstract Myotis grisescens (Gray Bat) is a federally endangered species distributed over the mid-South with a summer range that extends across the upper Tennessee River Basin, including southwest
Population Trends of Cave-Dwelling Bats in the Eastern Iberian Peninsula and the Effect of Protecting Their Roosts
TLDR
The selectivity of some species of bats for certain caves will be essential for the preparation of management plans for certain roosts, including Myotis myotis/blythii, Miniopterus schreibersii and R. ferrumequinum.

Comparative Numbers of Gray Bats (Myotis grisescens) at Four Maternity Caves in Northeastern Oklahoma in 1981 and 1991
The Oklahoma population of gray bats is mostly migratory, but may winter in isolated caves (3). This population inhabits the extreme southwestern portion of the species' range (the southwestern Ozark
Modified Cave Entrances: Thermal Effect on Body Mass and Resulting Decline of Endangered Indiana Bats (Myotis sodalis)
TLDR
It is shown that modifying cave entrances can degrade the bats’ winter habitat, and one mechanism by which this damage occurs is demonstrated, and the potential for recovery of 100,000 Indiana bats is offered.
SEASONAL VARIATION IN ACTIVITY PATTERNS OF THE ENDANGERED OZARK BIG-EARED BAT(CORYNORHINUS TOWNSENDII INGENS)
Abstract We studied occupation and activity at a hibernaculum and a maternity cave used by the endangered Ozark big-eared bat (Corynorhinus townsendii ingens). Big-eared bats remained active
Ecology of a Pleistocene Relict, the Western Big-Eared Rat (Plecotus townsendii), in the Southern Great Plains
TLDR
The small size of P. townsendii populations, rather severe ecological limitations, and high sensitivity to disturbance lead it to conclude that visitation of nurseries by humans could threaten the species' survival in the Great Plains.
Population ecology of the gray bat (Myotis grisescens): factors influencing early growth and development
TLDR
Growth success and survival of newly volant young Myotis grisescens were observed in colonies traveling a variety of distances between the roost cave and foraging areas, and success in,Lowth, percent of low-weight young, and mortality were closely correlated with the distances traveled by the colonies to their feeding areas.
Measurements, composition and behaviour of a large colony of the bat Pipistrellus pipistrellus
A study in Dorset, England, of a very large nursing colony of the common bat Pipistrellus pipistrellus provided some much needed basic taxonomic data for this species in the British Isles. Despite
Feeding Ecology of a Temperate Insectivorous Bat (Myotis Velifer)
TLDR
Emigration of males from nursery colonies in late spring and early summer and emigration of adult females soon after young were weaned may provide a mechanism to reduce competition for available food.
Activity patterns of the lesser horseshoe bat Rhinolophus hipposideros at summer roosts
TLDR
There is some limited evidence that increased colony size, perhaps through social interaction, may have influenced timing of departure at dusk and return at dawn in lesser horseshoe bats Rhinolophus hipposideros.
Timing of foraging flights of three species of bats in relation to insect activity and predation risk
TLDR
Protective tree cover may allow earlier evening emergence of bats and therefore provide access to more food, and have implications for the conservation ofbats and their habitats particularly at high latitudes.
Activity Patterns of Bats over a Desert Spring
TLDR
The hypothesis of continued year-round activity of bats in warmer areas of the southwest is presented as an alternative to hibernation or migration.
