The goal of this QR project was to identify how mussels responded to reductions in stream discharge. The primary objective was to identify the movement strategy used in response to diminishing water levels for each species. Additionally, determine if these movement strategies are consistent within genera or closely related species.

This SSP project resulted in one publication. Carbon storage was compared between impounded and naturally tidal freshwater marshes along the Lower Waccamaw River in South Carolina, USA. Soil cores were collected in (1) naturally tidal, (2) moist soil (impounded, seasonally drained since ~1970), and (3) deeply flooded "treatments" (impounded, flooded to ~90 cm since ~2002). Cores were analyzed for % organic carbon, % total carbon, bulk density, and 210Pb and 137Cs for dating purposes. Carbon sequestration rates ranged from 25 to 200 g C m-2 yr-1 (moist soil), 80-435 g C m-2 yr-1 (naturally tidal), and 100-250 g C m-2 yr-1 (deeply flooded). The moist soil and naturally tidal treatments were compared over a period...

This report serves as metadata and a user guide for five out of six hydrologic and landscape databases developed by the U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service, to describe data-collection, data-reduction, and data-analysis methods used to construct the databases and provides statistical and graphical descriptions of the databases. Six hydrologic and landscape databases were developed: (1) the Cache River and White River National Wildlife Refuges (NWRs) and contributing watersheds in Arkansas, Missouri, and Oklahoma, (2) the Cahaba River NWR and contributing watersheds in Alabama, (3) the Caloosahatchee and J.N. “Ding” Darling NWRs and contributing watersheds in Florida, (4)...

The striped newt (Notophthalmus perstriatus) is a small salamander that occurs in xeric habitats (e.g. scrub, sandhill, and dry flatwoods) of the lower coastal plain and northern peninsular Florida. Like most North American amphibians, the striped newt has a biphasic life cycle (i.e., aquatic egg and larval stages, as well as terrestrial juvenile/eft, and adult stages, and requires wetlands for reproduction. Striped newts, and a few other salamanders, are capable of adding an alternative life history pathway called paedogenesis; i.e.,larvae develop gonads and are able to reproduce without leaving the water. Paedomorphs can still transform into terrestrial forms at later time. Paedomorphosis affords benefits...

The objective of this SSP project is to Conduct an inventory of diamondback terrapins on Harris Neck, Blackbeard Island, Wassaw Island, and Wolf Island National Wildlife Refuges. Specific Objectives are to: Compile all existing records of diamondback terrapins from the refuges and surrounding area. Conduct systematic surveys using boat-based head counts on each refuge. Generate a map of terrapin relative densities and associated GIS files with all appropriate data. Cooperator Report Abstract – The diamond-backed terrapin (Malaclemys terrapin) is a small estuarine turtle distributed along the Atlantic and Gulf Coasts of the USA. Terrapin populations are declining throughout their range and one of the main causes...

This QR project contributed to the production of a scientific investigations report. From 1954 to 2004, water levels declined in the nontidal reach of the Apalachicola River, Florida, as a result of long-term changes in stage-discharge relations. Channel widening and deepening, which occurred throughout much of the river, apparently caused the declines. The period of most rapid channel enlargement began in 1954 and occurred primarily as a gradual erosional process over two to three decades, probably in response to the combined effect of a dam located at the head of the study reach (106 miles upstream from the mouth of the river), river straightening, dredging, and other activities along the river. Widespread recovery...

This SSP project resulted in a dissertation: A Dynamic Model of Semipalmated Sandpiper Migration:Implications For Conservation. By Jeffrey Allan Hostetler Abstract I developed a stochastic dynamic programming model of adult female Semipalmated Sandpiper (Calidris pusilla) spring migration for the purpose of adaptive management of wetlands along their migratory route. Semipalmated Sandpipers are small abundant shorebirds that migrate through Merritt Island National Wildlife Refuge, FL, Yawkey Reserve, SC, Pea Island National Wildlife Refuge, NC, and Delaware Bay on their way from the Caribbean and South America to arctic North American breeding grounds. The first three stopover sites mentioned include managed wetlands....

A final report was produced for this SSP project. The general objectives to this study were threefold, as follows: 1. To determine the environmental presence and abundance of Bden in headwater regions of river systems in the Southeastern United States through water samples evaluated for the presence of environmental DNA (eDNA). 2. To determine the presence of Bden infection in fauna of these headwater regions, including larval and adult amphibians as well as other potential reservoirs of infection. 3. To determine whether any association exists between water flow rate and associated stream parameters in headwater systems versus the presence/prevalence of Bden both in the environment and infecting amphibian host...

No products for this SSP project are available at this time This project involves the development of a management strategy for oak (Quercus spp.) scrub that will maximize the long-term demographic performance of Florida scrub-jays (Aphelocoma coerulescens). The project focuses on the Happy Creek Scrub Reserve Unit of Merritt Island National Wildlife Refuge, which is an area with an ecological legacy of fire suppression. The objective of this project is to determine how creation of bare ground by plowing could supplement prescribed burning to help maintain better habitat conditions for Florida scrub-jays.

This SSP project resulted in a final report and two publications. The effective conservation and management of at risk mussels in the lower Flint River Basin requires a credible assessment of the suitability of specific areas (habitats) to support each species and means to assess the potential risks, such as extinction due to fragmentation and isolation of populations. Such an approach should also allow for the integration of monitoring data so that reliable information on the status and distribution of at risk taxa can be updated as data are collected. The timely integration of monitoring data also is crucial for evaluating the success or failures of management actions to recover existing populations. The ultimate...

This SSP project resulted in a final report and two publications (Nest occurrence and survival of King Rails in fire-managed coastal marshes in North Carolina and Virginia, King Rail (Rallus elegans) Occupancy and Abundance in Fire Managed Coastal Marshes in North Carolina and Virginia). The project explored this use of Bayesian network modeling using the King Rail as a case study. Although Bayesian network (BN) models have been promoted to the conservation community as models well-suited to support adaptive management strategies, there have been few tests of these claims. To test the value of BNs to support U.S. Fish and Wildlife Service and U.S. Geological Service's Strategic Habitat Conservation approach to...
