A Biological Inventory of Eight Caves in Northwestern Georgia with Conservation Implications
Kurt A. Buhlmann - A biological inventory of eight caves in northwestern Georgia with conservation implications. Journal of Cave and Karst Studies 63(3): 91-98. A BIOLOGICAL INVENTORY OF EIGHT CAVES IN NORTHWESTERN GEORGIA WITH CONSERVATION IMPLICATIONS KURT A. BUHLMANN1 University of Georgia, Savannah River Ecology Laboratory, Aiken, SC 29802 USA A 1995 biological inventory of 8 northwestern Georgia caves documented or re-confirmed the presence of 46 species of invertebrates, 35 considered troglobites or troglophiles. The study yielded new cave records for amphipods, isopods, diplurans, and carabid beetles. New state records for Georgia included a pselaphid beetle. Ten salamander species were in the 8 caves, including a true troglobite, the Tennessee cave salamander. Two frog, 4 bat, and 1 rodent species were also documented. One cave contained a large colony of gray bats. For carabid beetles, leiodid beetles, and millipeds, the species differed between the caves of Pigeon and Lookout Mountain. Diplurans were absent from Lookout Mountain caves, yet were present in all Pigeon Mountain caves. A comparison between 1967 and 1995 inventories of Pettijohns Cave noted the absence of 2 species of drip pool amphipods from the latter. One cave had been contaminated by a petroleum spill and the expected aquatic fauna was not found. Further inventory work is suggested and the results should be applied to management strategies that provide for both biodiver- sity protection and recreational cave use. Georgia is a cave-rich state, with most caves occurring in 29 July; Nash Waterfall Cave [NW] on 5 August; and Pigeon two distinct physiographic regions, the Cumberland Plateau Cave [PC] on 16 July (a) and 30 July (b). -

Hay's Spring Amphipod
Endemic Amphipods in by Diane Pavek our Nation’s Capital Hidden away in shallow, subsurface groundwater communities, the entire known distribution of two tiny species is restricted to only a few springs along Rock Creek in the District of Columbia. Rock Creek Park protects native biodiversity not found elsewhere within the fragmented landscape of the greater Washington, D.C., metropolitan area. Legislation in 1890 established the Rock Creek Park as a unit of the National Park Service (NPS). Once the best sources of drinking water during the 1700s and 1800s, nearly all of the District’s original springs outside the parks have disappeared due to the diversion of rain water or direct piping into the sewers. Other springs and streams were entombed in concrete, filled in and paved over, or contaminated. Both of the park’s endemic species analyses, and species identifications.

Credentials and expertise A graduate of Grinnell College (B.A.) and Yale University (Ph.D.), I have devoted most of my scientific career to the study of the biology of subterranean animals, especially in caves. I have written four books and over 100 scientific articles on the subject of subterranean life. My first book, Cave Life, published in 1982 by Harvard University Press, has been cited nearly 500 times in the scientific literature. My research over the past ten years has focused on shallow subterranean habitats, such as the seeps where Hay’s and Kenk’s spring amphipods are found. This work is summarized in the forthcoming book, written with Tanja Pipan, Shallow Subterranean Habitats: Ecology, Evolution, and Conservation, to be published by Oxford University Press in June, 2014. Since 2002, under a variety of contracts and cooperative agreements, I have been working on Stygobromus amphipods in national parks of the National Capitol region, including Rock Creek Park, George Washington Memorial Parkway, and others. -
2015 Mammal Damage Management in Maryland and DC EA
ENVIRONMENTAL ASSESSMENT MAMMAL DAMAGE MANAGEMENT IN MARYLAND AND WASHINGTON D.C. Prepared By: UNITED STATES DEPARTMENT OF AGRICULTURE ANIMAL AND PLANT HEALTH INSPECTION SERVICE WILDLIFE SERVICES In Consultation With: MARYLAND DEPARTMENT OF NATURAL RESOURCES MARYLAND DEPARTMENT OF AGRICULTURE MARYLAND DEPARTMENT OF HEALTH AND MENTAL HYGIENE May 2015 SUMMARY Maryland’s wildlife has many positive values and is an important part of life in the state. However, as human populations expand, and land is used for human needs, there is increasing potential for conflicting human/wildlife interactions. This Environmental Assessment (EA) analyzes the potential environmental impacts of alternatives for United States Department of Agriculture, Animal and Plant Health Inspection Service, Wildlife Services (WS) involvement in the reduction of conflicts by mammals in Maryland, including damage to property, agricultural and natural resources, and risks to human and livestock health and safety. The proposed wildlife damage management activities could be conducted on public and private property in Maryland when the property owner or manager requests assistance and/or when assistance is requested by an appropriate state, federal, tribal or local government agency. The preferred alternative considered in the EA, would be to continue and expand the current Integrated Wildlife Damage Management (IWDM) program in Maryland. The IWDM strategy encompass the use of practical and effective methods of preventing or reducing damage while minimizing harmful effects of damage management measures on humans, target and non-target species, and the environment. Under this action, WS could provide technical assistance and direct operational assistance including non-lethal and lethal management methods, as described in the WS Decision Model (Slate et al. -

DOI:10.4311/2019LSC0125 BIODIVERSITY FROM CAVES AND OTHER SUBTERRANEAN HABITATS OF GEORGIA, USA Kirk S. Zigler1C, Matthew L. Niemiller2, Charles D.R. Stephen3, Breanne N. Ayala1, Marc A. Milne4, Nicholas S. Gladstone5, Annette S. Engel6, John B. Jensen7, Carlos D. Camp8, James C. Ozier9, and Alan Cressler10 Abstract We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemism is high; of the troglobionts, 17 (33 % of those known from the state) are endemic to Georgia and seven (14 %) are known from a single cave. We identified three biogeographic clusters of troglobionts. Two clusters are located in the northwestern part of the state, west of Lookout Mountain in Lookout Valley and east of Lookout Mountain in the Valley and Ridge. In addition, there is a group of tro- globionts found only in the southwestern corner of the state and associated with the Upper Floridan Aquifer. At least two dozen potentially undescribed species have been collected from caves; clarifying the taxonomic status of these organisms would improve our understanding of cave biodiversity in the state. -

With 8 figures Cryptic diversity within and amongst spring-associated Stygobromus amphipods (Amphipoda: Crangonyctidae) JOSHUA Z. ETHRIDGE1*, J. RANDY GIBSON2 and CHRIS C. NICE1 1Department of Biology, Texas State University, 601 University Drive, San Marcos, TX 78666, USA 2San Marcos US Fish and Wildlife Service, San Marcos, TX, USA Received 3 May 2012; revised 14 September 2012; accepted for publication 24 September 2012 Multiple species of troglomorphic, spring-associated Stygobromus amphipods, including the endangered, narrow- range endemic Stygobromus pecki, occupy sites in the Edwards Plateau region of North America. Given the prevalence of cryptic diversity observed in disparate subterranean, animal taxa, we evaluated geographical genetic variation and tested whether Stygobromus contained undetected biodiversity. Nominal Stygobromus taxa were treated as hypotheses and tested with mitochondrial sequence cytochrome oxidase C subunit 1, nuclear sequence (internal transcribed spacer region 1), and AFLP data. Stygobromus pecki population structure and diversity was characterized and compared with congeners. For several Stygobromus species, the nominal taxonomy conflicted with molecular genetic data and there was strong evidence of significant cryptic diversity. Whereas S. pecki genetic diversity was similar to that of congeners, mitochondrial data identified two significantly diverged but sympatric clades. AFLP data for S. pecki indicated relatively recent and ongoing gene flow in the nuclear genome. These data for S. pecki suggest either a substantial history of isolation followed by current sympatry and ongoing admixture, or a protracted period of extremely large effective population size. This study demonstrates that Edwards Plateau Stygobromus are a complex, genetically diverse group with substantially more diversity than currently recognized. -

Appendix A2: Comprehensive Wildlife Conservation Strategy Species Group Reports for Crustacea/Meristomata Prepared by New York State Department of Environmental Conservation staff in cooperation with Cazenovia College and the Riverhead Foundation for Marine Research in support of the Comprehensive Wildlife Conservation Strategy prepared for New York as required by the United States Fish and Wildlife Service's State Wildlife Grants Program 27-Sep-05 State Wildlife Comprehensive Plan - DRAFT Species Group Report For American lobster 9/27/2005 Taxa Group: Crustacea/Meristomata Species Group: American lobster Threats: The American lobster population in New York faces a number of serious threats. Any single one of the stressors may not be fatal, but in combination they are potentially very harmful. In Long Island Sound (LIS), fishing effort increased dramatically as the lobster population increased in the 1990's. A large die off occurred to the western LIS lobster population during 1999, and the population has continued to decline through 2003. Fishing effort declined as the population size decreased, but not at the same rate. The number of traps set in LIS is two to three times higher than the 1980's when the lobster population was at a similar size. A large research initiative was conducted to determine the cause (s) of the 1999 die off. Final results indicate that the die off was probably due to a number or factors. During 1999, a combination of high bottom water temperature, low dissolved oxygen, a storm at the end of August that mixed the water column and increased bottom water temperatures 1 - 2 degrees in 24 hours, and paramoeba infection probably combined to cause the lobster die off. -
The Occurrence of the Troglobitic Amphipod, Stygobromus Tenuis
Int. J. Speleol. 14 (1984-1985), pp. 31-37 The occurrence of the troglobitic amphipod, Stygobromus tenuis tenuis (Smith) (Crangonyctidae) in the Taconic Mountains of southwestern Massachusetts (USA): a case for the existence of a subterranean refugium in a glaciated region Douglas G, Smith- SUMMARY Stygobromus t. tenuis is one of only two species of troglobitic amphipods known to occur in the New England physiographic province. The rarity of subterranean organisms in New England is attributed to limited karst de- velopment and eradication of organisms from the region during glacial ti- mes. Traditionally it has been believed that those troglobitic species presen- tly occurring north of the glacial terminus migrated there following glacial retreat from refugia south of the areas influenced by glacial conditions. However, a few recent studies favor the existence of subsurface refugia in glaciated regions during glacial times. Stygobromus t. tenuis is recorded from springs connected with deep, solution zone aquifers in the Taconic Mountains of western New England, an area well north of the glacial ter- minus. It is suggested that these aquifers served as a refugium for S. t. tenuis during the latter part of perhaps all of the Pleistocene Epoch. INTRODUCTION The New England physiographic province, relative to other provinces in eastern North America, is not known to contain a diverse or widespread troglobitic fauna. There are two reasons for this. First the region does not have the geological features conducive to the development of an extensive troglobitic fauna. • Museum of Zoology, University of Massachusetts, Amherst, Massachusetts 01003-0027. 32 D.G. SMITH The few areas within the New England province that are chara- cterized by carbonate rocks are limited to a narrow north-south trending zone along the western margin of the region. -
Chapter 6 – Conservation Actions – Species
Chapter 6 – Conservation Actions – Species Birds of Greatest Conservation Need Bobolink Dolichonyx oryzivorus STATUS: Populations in the eastern U.S. have declined since the early 1900s. North American Breeding Bird Survey data indicate a significant population decline in North America in recent decades. Status within the District of Columbia is undetermined. RANGE: Breeds in the northern United States and southern Canada and winter in southern South America from Peru to Argentina. It is a passage migrant through the District of Columbia. LOCAL HABITAT: Kenilworth Park, Anacostia Park, Rock Creek National Park, and Fort Circle Parks area. SPECIES ECOLOGY: Bobolinks use tall grass fields, pastures, and grain fields for breeding. In some areas, they favor hayfields in close association with dairy farms. In spring and summer, their diets consists largely of insects, especially caterpillars, grasshoppers, and beetles, but in fall it also includes large quantities of weed seeds, wild rice, and bristlegrass. Nests are usually placed in a scrape, either natural or created by the female. Clutch size varies from 4 to 7 eggs. THREATS: Primary threats are due to loss of suitable habitat. Changing agricultural practices and the loss of farmland to development are key factors contributing to species decline. CONSERVATION ACTION: : Need to identify and conserve grasslands. Studies to determine precise status and habitat use within the District. SITE MAP: 4 REFERENCES: 1-4 Acadian Flycatcher Empidonax virescens STATUS: BBS data from 1966 through 1989 show stable populations in the Eastern region and in neighboring Maryland. RANGE: Breeds from southern Minnesota east through southern New England, south to Gulf Coast and central Florida.
