“…Young can fly at three weeks of age, but do not hunt until they are fully weaned at six weeks of age. Even though females become sexually mature by the first autumn the males do not (Kunz and Martin 1982). When these female maternity colonies start forming, the males and non-breeding females start forming bachelor colonies.…”

“…The young bats can produce vocal sounds within a few hours after birth, which play an important role in the mother's identification of her pup among the masses. Within one week, the pups produce a call that is very adult-like (Kunz and Martin 1982). Young can fly at three weeks of age, but do not hunt until they are fully weaned at six weeks of age.…”

“…Sperm is stored by females until they awake from hibernation (Weyandt et al 2005). The gestation occurs during spring and lasts between 56-100 days, depending on how the maternal colony is arranged (Kunz and Martin 1982). Gestation is shorter when females cluster together because they are able to maintain a higher body temperature (Schwartz and Schwartz 2001).…”

“…Females are said to be larger in size than males (Kunz and Martin 1982) and significant During summer months, maternal colonies consist of only females and their offspring, and generally utilize warmer areas of the caves, typically near openings to assist in thermoregulation and rapid development of offspring. Other colonies (e.g., bachelor colonies) will often disperse to utilize a variety of roosts (Schwartz and Schwartz 2001).…”

approved:________________________________________________________There is limited understanding of habitat use by bats in the Great Plains and few steps taken toward their conservation, relative to other wildlife. This gap of knowledge, including specific knowledge of two Species in Need of Conservation (SINC) noted by the state of Kansas in the Red Hills region, must be filled for adequate bat conservation. I investigated bat distribution in relation to encroaching woody vegetation and elevation on both the landscape level and local scale habitat (e.g., tree cover) used within riparian corridors (Chapter 2). Acoustic data were used to model probability of occurrence in relation to vegetative and topographic characteristics within the region. The probability of occurrence of one species, Myotis velifer, was positively associated with tree canopy cover and negatively associated with elevation. I obtained habitat use within riparian corridors by mist netting live bats. The capture rates of M. velifer and Corynorhinus townsendii were found to be positively related with canopy cover. I also obtained information on the physical characteristics of summer roosting locations of a SINC species in Kansas, Antrozous pallidus, by tracking radioed individuals to their diurnal roosting sites (Chapter 3). Information gathered from these investigations, and published research, also was used to construct a recovery plan (Chapter 4) that will be submitted to the Kansas Department of Wildlife, Parks, and Tourism. This plan will help guide conservation and management decisions for these two species by including roosting and foraging habitat information that is critical for their persistence within the state of Kansas.

Hibernacula selection by Townsend's big‐Eared bat in southwestern Colorado

2011

In western United States, both mine reclamations and renewed mining at previously abandoned mines have increased substantially in the last decade. This increased activity may adversely impact bats that use these mines for roosting. Townsend's big‐eared bat (Corynorhinus townsendii) is a species of conservation concern that may be impacted by ongoing mine reclamation and renewed mineral extraction. To help inform wildlife management decisions related to bat use of abandoned mine sites, we used logistic regression, Akaike's information criterion, and multi‐model inference to investigate hibernacula use by Townsend's big‐eared bats using 9 years of data from surveys inside abandoned mines in southwestern Colorado. Townsend's big‐eared bats were found in 38 of 133 mines surveyed (29%), and occupied mines averaged 2.6 individuals per mine. The model explaining the most variability in our data included number of openings and portal temperature at abandoned mines. In southwestern Colorado, we found that abandoned mine sites with more than one opening and portal temperatures near 0°C were more likely to contain hibernating Townsend's big‐eared bats. However, mines with only one opening and portal temperatures of ≥10°C were occasionally occupied by Townsend's big‐eared bat. Understanding mine use by Townsend's big‐eared bat can help guide decisions regarding allocation of resources and placement of bat‐compatible closures at mine sites scheduled for reclamation. When feasible we believe that surveys should be conducted inside all abandoned mines in a reclamation project at least once during winter prior to making closure and reclamation recommendations. © 2010 The Wildlife Society.
