This book was released on 1998 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The southeastern myotis (Myotis austroriparius) is a medium-sized bat with grayish-brown, woolly fur. This species primarily is found in the southeastern United States. Its range extends from southeastern North Carolina south to peninsular Florida, west to eastern Texas and Oklahoma, and north to western Kentucky, southern Illinois, and southern Indiana. The southeastern myotis is considered a species of special concern because of significant population declines. It migrates between cooler winter caves used as hibernacula and warmer summer caves used for rearing young. In noncave regions, the southeastern myotis roosts in large hollow trees or man-made structures. The southeastern myotis has been documented on at least two military installations in the southeastern United States. This report is one of a series of Species Profiles being developed for threatened, endangered, and sensitive species inhabiting southeastern United States plant communities found on military installations.

This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gray bat (Myotis grisescens) is a medium-sized bat with gray or chestnut-brown fur. The species was listed as Federally endangered in 1976 throughout its range by the U.S. Fish and Wildlife Service, primarily due to human disturbance, environ- mental disturbance, and impoundment of waterways. Gray bats are year-round cave residents but migrate between caves in wintering and summering areas of the midwestern and southeastern United States. Populations are mainly concentrated in Alabama, Arkansas, Missouri, Tennessee, and Kentucky. The species was been documented on one military installation in the southeastern United States; installations with suitable habitat in other sections of the United States should also benefit from this profile. This report is one of a series of Species Profiles being developed for threatened, endangered, and sensitive species inhabiting southeastern United States plant communities. The work is being conducted as part of the Department of Defense (DoD) Strategic Environmental Research and Development Program (SERDP). The report is designed to supplement information provided in plant community management reports for major United States plant communities found on military installations. Information provided on the gray bat includes status, life history and ecology, habitat requirements, impacts and causes of decline, habitat assessment techniques, inventory and monitoring, and management and protection.

This book was released on 2020-03-31 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Florida Scrub Jays are an excellent example of a cooperative-breeding species, in which adult birds often help raise offspring not their own. For more than a decade Glen E. Woolfenden and John W. Fitzpatrick studied a marked population of these birds in an attempt to establish a demographic base for understanding the phenomenon of "helping at the nest." By studying both population biology and behavior, the authors found that habitat restraints, rather than kin selection, are the main source of the behavior of Florida Scrub Jays: the goal of increasing the number of close relatives other than descendants in future generations is of relatively minor importance in their cooperative-breeding behavior. The Florida Scrub Jay lives only in the Florida oak scrub. All acceptable habitat is constantly filled with breeders. Each year about half of the pairs are assisted by one to several nonbreeding helpers. This book provides extensive data on fecundity, survivorship, relatedness, and dispersal to establish the demographic milieu and to address questions arising out of observed helping behavior--whom, how, when, and why the helpers help.

This book was released on 2016 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each June, surveys are conducted at Jonathan Dickinson State Park in order to monitor the population status of the Florida Scrub-Jay (Aphelocoma coerulescens), the only avian species endemic to the state of Florida. These birds are limited to the rare oak scrub community, a habitat that is under constant threat due to human development. Florida Scrub-Jays are listed as a threatened species under the Endangered Species Act and all of Florida’s populations are in decline. Jonathan Dickinson State Park organizes surveys that collect vital information about the species to better understand how to conserve the fire-dependent oak scrub that they inhabit. The results of this study indicate that efforts to restore the scrub habitat through prescribed burning have been successful at JDSP since the population of Florida Scrub-Jays has stabilized and the birds have dispersed into new areas of the park.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Florida Scrub Jays (FSJs) have declined significantly in numbers because of habitat destruction. FSJs have disappeared entirely from six counties in Florida, and their numbers have decreased substantially in seven additional counties. I estimated the total population size in 1982 to be 15,330-22,530 birds, of which 13,100-20,310 were on protected sites. FSJ numbers will continue to decline as the commercial development of Florida proceeds, but the total population size should stabilize at about 12,780-19,780 birds in a few decades. The greatest densities of FSJs are in areas with oak thickets 1-3m tall covering 50-75% of the ground, 10-5-% bare ground, and scattered small trees. Some FSJ populations, however, are found in areas with very few oaks, demonstrating their ability to survive in marginal habitats. Fire is effective, and sometimes essential, in maintaining the habitat in a suitable condition. Mechanical clearing of vegetation, including clear-cutting in Ocala National Forest (ONF), can be an effective substitute for fire. Scrub Jays in ONF inhabit stands of sand pine scrub clearcut from 1965-1978. Clearcuts can support FSJs only from about 3-5 to 12-15 years after clearing. By the time a young male FSJ is old enough to claim part of his parents' territory, the habitat may no longer be suitable. Because of the continual creation of new habitat, FSJs in ONF are found in smaller groups than those at Archbold Biological Station, Florida. Blue Jays in Florida typically breed as pairs, but one nest was found that was attended by two males and one female. Behavior of the adults at this nest suggests that this incident was unusual. Florida Blue Jays do not defend territories, but have broadly overlapping home ranges. The evolution of cooperative breeding in New World jays is discussed. Some of the observed forms of cooperative breeding may not be adaptive, but represent either responses to life in heavily disturbed habitats or the expression of normal parental behavior before a bird becomes a breeder.

Book excerpt: A portrait of a species on the brink The only bird species that lives exclusively in Florida, the Florida Scrub-Jay was once common across the peninsula. But as development over the last 100 years reduced the habitat on which the bird depends from 39 counties to three, the species became endangered. With a writer's eye and an explorer's spirit, Mark Walters travels the state to report on the natural history and current predicament of Florida's flagship bird. Tracing the millions of years of evolution and migration that led to the development of songbirds and this unique species of jay, Walters describes the Florida bird's long, graceful tail, its hues that blend from one to the next, and its notoriously friendly manner. He then focuses on the massive land-reclamation and canal-building projects of the twentieth century that ate away at the ancient oak scrub heartlands where the bird was abundant, reducing its population by 90 percent. Walters also investigates conservation efforts taking place today. On a series of field excursions, he introduces the people who are leading the charge to save the bird from extinction--those who gather for annual counts of the species in fragmented and overlooked areas of scrub; those who relocate populations of Scrub-Jays out of harm's way; those who survey and purchase land to create wildlife refuges; and those who advocate for the prescribed fires that keep scrub ecosystems inhabitable for the species. A loving portrayal of a very special bird, Florida Scrub-Jay is also a thoughtful reflection on the ethical and emotional weight of protecting a species in an age of catastrophe. Now is the time to act, says Walters, or we will lose the Scrub-Jay forever.
