Extractions: Austin, Texas 78716 Updated 4/24/01 IMAGES REFERENCE INFORMATION 1. Spotted bat ( Euderma maculatum ) roosting in rock crevice (#1 of 10) The spotted bat ( Euderma maculatum ) is one of America's most striking mammals. Initially thought to be extremely rare, the spotted bat is now known to occupy a rather large range throughout western North America from southern British Columbia to northern Mexico. Spotted bats appear to feed almost exclusively on moths, using high-pitched echolocation calls that are audible to humans. This speciesÂ’ population status is uncertain and more information is needed about its habits and life history. 2. Lesser long-nosed bat ( Leptonycteris curasoae ) in flight to saguaro flower (#2 of 10) The lesser long-nosed bat ( Leptonycteris curasoae ) is one of three North American species that feed exclusively on the fruit and nectar of night-blooming cacti including saguaro and organ pipe, as well as many species of agave. Bats are important to the reproductive biology of these plants. For example, in the absence of bats, the seed set of the agave falls to one three-thousandth of normal. Lesser long-nosed bats are found in southern Arizona, southwestern New Mexico and throughout Mexico and Baja California. In 1988, these bats were listed by the U.S. Fish and Wildlife Service as endangered. Roost disturbance and possible effects of habitat loss such as the over-harvesting of agaves in Mexico represent their primary threats.

Extractions: Bats may be the most misunderstood animals in the United States, although as consumers of enormous numbers of insects, they rank among the most beneficial. Almost all United States bats, and 70 percent of the bat species worldwide, feed almost exclusively on insects and are thus extremely beneficial. In fact, bats are the only major predators of night-flying insects. One bat can eat between 600 and 1,000 mosquitoes and other insect pests in just one hour (Organization for Bat Conservation) While most United States bat species are insectivorous, bats in other parts of the world feed on a variety of items in addition to insects. Many species feed primarily on fruit, while several types feed on nectar and pollen. Fruit bats perform an extremely important function as seed dispersers. Nectar eating bats, including the federally-listed endangered

All photos will be properly credited and will remain the property of the photographer. Status: Former Candidate (Note: As of February 28, 1996, this species is no longer listed as a Candidate species. However, it remains a species of management concern.) Historical Status: The pale townsend's big-eared bat historical range is believed to be similar to its present range, however, throughout its range its abundance and distribution is suspected to be in decline. Present Status: The pale townsend's big-eared bat is widespread but rare in the Great Plains and northern Rocky Mountains. In the Snake River Plain in Idaho, the abundance and distribution of this bat was documented to have declined substantially in the 1980's. In Montana, extensive surveys have found only 4 maternal colonies and less than 12 hibenacula (place of hibernation). Habitat: The pale townsend's big-eared bat is a cave dwelling species and occurs in a variety of habitats, typically shrub-steppe or forest edge. In the warm months, these bats roosts in caves, mineshafts, rocky outcrops, and occasionally in buildings. This bat seldom leaves these roosts until afler dark and thus rarely is observed in flight. They hang from an open ceiling and frequently hang by one foot. During the winter months they hibernate in caves or mines, singly or in small groups. Even in cold weather these bats often move between caves. During hibernation, the bats ears are folded on the back like a ram's horns but if the bats are disturbed, the ears unfold and move in circles like antennae. In spring, female bats will form nursery colonies up to 1000 individuals. Males and barren females generally are solitary in the warm months.

Extractions: AREA-[ ARTICLE ] EIGHT MORE North American bats have been added to the U.S. Fish and Wildlife Service list of species being considered as candidates for endangered or threatened status. This brings the total to an alarming 56 percent of our bat species that are endangered or are under consideration for listing. There are 43 bat species in the United States and Canada. Bats now have the highest percentage of endangered or candidate species among all land mammals in the United States and Canada. The new listings were included in the Federal Register published in November 1994. Although inclusion on the list is not a formal proposal for endangered or threatened status, it is the first step toward gaining official protection under the Endangered Species Act (ESA). All of the additional bats on the new list are Category 2 status, which means that while there is enough information to indicate that a proposal may be appropriate, conclusive data on biological vulnerability and threat are not currently available. The additional North American bats on the list are Idionycteris phyllotis (Allen's lappet-browed bat)
Id-103 KENTUCKY'S ENDANGERED & THREATENED SPECIES endangered and threatened species in Kentucky most likely to be affected by pesticide use include bats, mussels, Mammoth http://www.ca.uky.edu/agc/PUBS/id/id103/id103.htm
Extractions: Animals or plants are classified as endangered if they face extinction throughout all or a large part of their range. Plants or animals are classified as threatened if they are likely to become endangered in the foreseeable future. Only a few animals and plants in Kentucky are endangered. Several animals, like the white-tailed deer, are more abundant today than at any other time during history. Animals and plants can be abundant, common, rare, threatened or endangered in different parts of their ranges. For example, the American alligator has been classified as endangered or threatened in some areas, whereas in other areas it is abundant and may be legally harvested under the supervision of the state wildlife agency. The number and types of animals and plants listed as threatened or endangered changes constantly because new species are added or others are deleted. Unfortunately, species are usually removed from the list because they have become extinct. The list provided in this publication is subject to change. The most current information on endangered and threatened species in your area may be obtained by contacting the U.S. Fish and Wildlife Service, the Kentucky Department of Fish and Wildlife Resources, the Kentucky State Nature Preserves Commission or the Cooperative Extension Service.

Gray Bat gray bat was added to the US List of endangered and threatened Wildlife and privateconservation agencies are all working to preserve gray bats and their http://midwest.fws.gov/endangered/mammals/grbat_fc.html
Extractions: Gray Bat The gray bat is an endangered species. Endangered Species are animals and plants that are in danger of becoming extinct. Threatened species are animals and plants that are likely to become endangered in the foreseeable future. Identifying, protecting, and restoring, endangered and threatened species is the primary objective of the U.S. Fish and Wildlife Service's endangered species program. What is the Gray Bat? Scientific Name Myotis grisescens Appearance - Gray bats are distinguished from other bats by the unicolored fur on their back. In addition, following their molt in July or August, gray bats have dark gray fur which often bleaches to a chestnut brown or russet. They weigh 7-16 grams. The bat's wing membrane connects to its ankle instead of at the toe, where it is connected in other species of Myotis Habitat - With rare exceptions, gray bats live in caves year-round. During the winter gray bats hibernate in deep, vertical caves. In the summer, they roost in caves which are scattered along rivers. These caves are in limestone karst areas of the southeastern United States. They do not use houses or barns. Reproduction - Females give birth to a single young in late May or early June.

(Photograph by Dr. J. Scott Altenbach. Department of Biology, University of New Mexico) Other species of bats, especially in temperate zones, are insectivorous and collectively consume large quantities of insects. Just as pollinating activities of bats are important to plant ecology, the insectivorous food habits of bats play an important role in maintaining a balance among insect populations. Although studies of bats have demonstrated some flexibility in food habits over time, most species appear to be specialized to pursue and capture selected kinds or categories of insects. Furthermore, bats are dependent upon a reliable and consistent "supply" of prey, even though specific insect populations grow and disappear over the course of a summer season. Changes in worldwide insect population occurrence or distribution can be expected to affect numbers and species diversity of bats. Figure 2.

Molecular data are being used to identify patterns of genetic diversity among endangered and threatened species. Thus far, the target species have included endangered Chinese giant salamanders and threatened Asian Bullfrogs and North American desert tortoises and this research is important for both North Amereican and Asian interests. The applications of the analyses include reintroductions, captive propagation, and setting aside wildlife protection areas. Phylogenetic relationships of rattlesnakes. Very little is known about the genealogical relationships of more than 30 species of rattlesnakes. Centre researchers are using DNA sequence data to unravel the evolutionary relationships of the species, and analyses will allow us to understand the evolution, ecology, and behaviour of rattlesnakes, their geographic distribution and other life attributes. These analyses may also allow for the more effective treatment of venomous snake bites.

Other large North American predators the grizzly bear, wolves, panthers were nearly hunted out by fearful settlers. Alligators were quickly eradicated at the fringes of their range, but in their Deep South heartland, they hung on by the millions until after World War I. Alligators weren't threatened until the fashion industry decided their skins were chic. By the 1920s, 200,000 Florida alligators annually became boots, shoes, wallets, purses, luggage, curios, belts, even clocks.

Endangered and Threatened Species Hawaiian Species Pacific Species Critical Habitat Updates The Endangered Species Program conserves endangered and threatened species and the ecosystems upon which they depend. Conserving endangered and threatened species is necessary to preserve our natural heritage for future generations and to maintain our quality of life. Conserving ecosystems benefits all users of ecosystem resources and is essential to maintaining our nation's long term economic prosperity. A species can be listed under one of two categories, endangered or threatened, depending on its status and the degree of threat it faces. Endangered Species are plants and animals that are in immediate danger of becoming extinct and need protection to survive. Threatened Species are those that are declining in numbers and might become endangered if conservation efforts are not immediately taken. As you browse through the endangered species section, you will learn that island ecosystems are very fragile and that island species depend on one another for survival. It will also become apparent that the major causes for the decline of some species are due to urban development, which takes over the limited habitat of native plants and animals, and the introduction of alien species, which compete for food and habitat and sometimes become predators of native species.
Fort Bliss Site A Refuge For Endangered Bats She said about 40 percent of the country's bats are either candidates forendangerment or are already on endangered or threatened species lists. http://aec.army.mil/usaec/publicaffairs/update/sum96/bats.htm
Extractions: Fort Bliss PAO Fort Bliss has taken significant steps to protect endangered pallid bats including the one pictured above that live on the installation. An unused storage building at Fort Bliss, Texas, has become home to the nation's largest colony of pallid bats. The bats, so named because of their blond fur, use the site on McGregor Range as a maternity roost. The Army conducts more than 4,000 training missions and maneuvers a year at Fort Bliss, which works hard to preserve its environment. Dr. Donna J. Howell, an ecologist with the Fort Bliss Directorate of the Environment, said the storage building at the range is probably the most protected bat colony in America, with guards limiting public access. The installation has taken the building off military usage and made it a preserve strictly for the bats. The McGregor site is significant because of its rarity. Maternity roosts must meet specific temperature and humidity conditions and be free from human intrusion. Additionally, the area must be rich in insects to feed young bats, Dr. Howell said. Habitat destruction and pesticides are two major threats to bats, Dr. Howell said. Scientific activities such as banding bats for identification and tracking purposes can also cause concern, because the banding process can cut the skin and cause the bat to bleed to death.
