With a wingspan of 20 inches (50 cm), it is Florida’s largest bat and the third largest of all 48 species of bats in the United States. Fur color varies from brown to gray to black. Figure 2.

    MOLECULAR SYATEMATICS OF BONNETED BATS (MOLOSSIDAE: EUMOPS) BASED ON MITOCHONDRIAL AND NUCLEAR DNA SEQUENCES A Thesis Presented to the Faculty of the Graduate School of Angelo State University In Partial Fulfillment of the Requirements for the Degree MASTER OF SCIENCE by: SARAH NICHOLE BARTLETT May 2012 Major: Biology ACKNOWLEDGMENTS I would first like to express my deepest gratitude to my major advisor Dr. Loren Ammerman for donating countless hours to this project and to my success as an undergraduate and graduate student at Angelo State University. She introduced me to the joys of late night field work and the experience I have gained under her advisement is sure to prove invaluable. I would also like to thank my family and friends who offered the encouragement and support I needed to complete this project. The other students working in Dr. Ammerman’s lab also deserve acknowledgment. I always knew someone would be around to bounce ideas off of or to ask those simple questions you just cannot remember the answer to. For editing manuscripts and sage writing advice, due thanks are given to Dr. Ammerman, Dr. Michael Dixon, Dr. Terry Maxwell, and Dr. Ned Strenth. All of the samples that I used in my project were collected by other people whom I would like to thank for their diligence in collecting tissue samples, without which this project would have been impossible. I have had the pleasure to be a part of multiple field work excursions both with Dr. Ammerman and my fellow students both in Texas and in Arizona and can relate to the hard work and dedication it takes to man the nets all night and collect tissues in the dark before turning in for the night.

To place these novel Conservation status threats in context for a group of mammals that provides important ecosystem services, we performed the first Disease comprehensive conservation status assessment focusing exclusively on the 45 species occurring in North America Geographic patterns north of Mexico. Although most North American bats have large range sizes and large populations, as of 2015, Wind energy 18–31% of the species were at risk (categorized as having vulnerable, imperiled, or critically imperiled NatureServe conservation statuses) and therefore among the most imperiled terrestrial vertebrates on the con- tinent. Species richness is greatest in the Southwest, but at-risk species were more concentrated in the East, and northern faunas had the highest proportion of at-risk species. Most ecological traits considered, including those characterizing body size, roosting habits, migratory behavior, range size, home range size, population density, and tendency to hibernate, were not strongly associated with conservation status.

  • Preliminary Report Florida Bonneted Bat
    Preliminary Report Florida Bonneted Bat Acoustic Monitoring Project: Identifying critical habitat within Miami-Dade County in order to protect the rarest bat in the United States Executive Summary Between May – December 2019 Bat Conservation International installed ten acoustic detectors across Miami-Dade County to identify the ranging behavior and distribution patterns of the Federally Endangered Florida bonneted-bat (FBB). In total, over 3.7 million bat calls were recorded over 684 nights from the ten sites. While FBB calls were recorded across all ten sites, the large open area used as a car park at Zoo Miami showed the greatest activity with an average of over 6,000 calls/night compared to 1,000 calls/night for the next active site. At Zoo Miami, the FBB’s appeared to be specifically selecting this large open area as a detector placed in a more forested area recorded far less bat activity (ca. 328 calls/night). While the importance of the Zoo Miami site at a County level was unexpected, based on the wing morphology of this species, the results highlights the importance of large, open and dark spaces this species can utilize for foraging. Combined with the population of FBB’s using the artificial bat boxes on Zoo Miami grounds (45 individuals, which is the second largest known population in Florida), the Zoo Miami grounds, including the parking area, should be considered as critical habitat for this species. Introduction With one of the smallest range distributions of any bat species in the United States, the Florida bonneted bat (Eumops floridanus; Molossidae; FBB) is endemic to south Florida and listed as a federally endangered species (U.S.

A species action plan for the Florida bonneted bat. Tallahassee, Florida. Florida Fish and Wildlife Conservation Commission ii EXECUTIVE SUMMARY EXECUTIVE SUMMARY The Florida Fish and Wildlife Conservation Commission (FWC) created this plan based on the determination of the Biological Review Group that the Florida bonneted bat (Eumops floridanus) should remain listed as Threatened in the State of Florida. The U.S. Fish and Wildlife Service proposed to list the Florida bonneted bat in 2012, and the listing was accepted in 2013, adding the Florida bonneted bat to the list of Endangered Species under the Endangered Species Act of 1973. Critical habitat was not designated with the listing, but is expected to be proposed by 2014. The goal of this plan is to improve the conservation status of the Florida bonneted bat so the species is secure within its historical range.
