This QR project produced an annual report. Submersed aquatic vegetation (SAV) communities are highly productive ecosystems that provide significant ecological benefits within coastal areas, including support for many important species of fish and wildlife. Despite their critical importance, and loss globally, we lack consistent baseline data on SAV resources across the coastal salinity gradient. This project is part of a larger funded effort which has the overall objectives to document the occurrence and abundance of SAV resources (e.g., coverage, composition, seed resources) within the northern Gulf of Mexico over three years, to quantitatively assess environmental factors affecting SAV spatial and temporal variation,...

This SSP project conducted from FY2002-2006 had several parts: The optimal control model portion which was worked on by Scott Duke Sylvester for his dissertation research. A spore dispersal study conducted by Allison Snow (USGS employee based at the Arthur R. Marshall Loxahatchee NWR) A spore germination study conducted by Erynn Call (USGS employee based at the Arthur R. Marshall Loxahatchee NWR) A user interface for Scott's model done by Gareth Mann and Leonard Pearlstine, University of Florida. An analysis of Lygodium in the refuge from IKONOS data done by Ken Rutchey at South Florida Water Management District. The first and last projects were not funded with SSP funds, but are considered part of the project....

Products from this SSP project consisted of a large amount of GIS data, analysis, and maps. There were shared GIS personnel for FWS served by this SSP project that generated lots of maps and direct services.

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....

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...

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...

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 (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...
