Geographical Trends in Ecosystem Function and Biodiversity of Wetlands as a Surrogate for Climate Change

Extreme drought and temperature in the southeastern United States may become more frequent in the future, and any  extreme shifts in climate condition are likely to have effects on wetland ecosystem function. USGS research predicts the effects of climate change by shifts in function and biodiversity across existing  climate gradients in baldcypress swamps.

Alabama Barrier Island Restoration Assessment at Dauphin Island

Dauphin Island, Alabama, is the only barrier island providing protection to much of Alabama's coastal natural resources. Severely impacted by repeated extreme events, like Hurricane Katrina and Deepwater Horizon oil spill, USGS and partners are conducting a joint study to evaluate the feasibility of certain alternatives to increase resiliency and sustainability of the island.

Determining the Ploidy and Resultant Reproductive Capability of Artificially Spawned and Wild Caught Asian Carp

The invasive grass carp and black carp are artificially spawned to produce triploids, which means they have three sets of chromosomes and are sterile. WARC scientists invented an early ploidy prediction process for produced fry, and a post-mortem assessment method for carp caught either in the wild or sold and hauled live to other states.

Climate Change Effects on Coastal Marsh Foundation Species

Mangrove forests have migrated inland over the past few decades at many locations along the northern Gulf of Mexico coast. This expansion has been attributed to factors associated with climate change, such as increased salinity resulting from sea-level rise and longer intervals between winter freezes, which can kill cold-intolerant mangrove species.

Asian Tiger Shrimp Distribution and Genetics

The Asian tiger shrimp began appearing in commercial shrimp catches in 2006. They grow larger than native shrimp and are known to be fierce predators - so shrimpers and managers are concerned about the potential effects this species might have.

GIS and Custom Application Support for the Gulf Coast Ecosystem Restoration Council

 The scientists at the Wetland and Aquatic Science Center (WARC) have provided coastal restoration project managers and decision makers with GIS planning, database and custom application capacity since 1992. The scope and complexity of this support has increased over the years and has resulted in the development of a comprehensive geospatial and advanced application teams that provide decision...

Spatial Analysis Support for Coastal Wetlands Planning, Protection and Restoration Act (Breaux Bill) Planning Activities

WARC first implemented geographic information systems (GIS) in 1980 to help monitor the nature and extent of wetland habitat changes. The center continues to use GIS, remote sensing, and other computer based technologies to address a wide range of natural resource related issues.

Adaptive Regulation of Waterfowl Harvests Using Incomplete Survey Information

The 2011 (Draft) Supplemental Environmental Impact Statement on Migratory Bird Hunting (EIS) offers four alternatives concerning the timing of the regulatory process for setting waterfowl hunting seasons. The no-change alternative involves a process by which most proposals for hunting seasons are developed in response to survey information that becomes available in early summer, such as...

Visual Guide to Louisiana Plants: A Web Based Searchable Plant Database and Photo Gallery of the Plants of Louisiana

Quality photographs of plant species are rare on the internet, often difficult to find, and are generally copyrighted, preventing them from being used by government agencies and non-government organizations, academics and the general public.

Geographic Information and Technical Support

USGS WARC first implemented geographic information systems (GIS) in 1980 to assist in monitoring the nature and extent of wetland habitat changes. Today, geographers and support staff create, maintain, and use geospatial data to analyze restoration efforts in Louisiana.

Louisiana Coastal Area (LCA) Ecosystem Restoration Program – Adaptive Management and Monitoring Planning and Implementation Support

Adaptive management (AM) is an iterative science-based process that accepts uncertainties in ecological systems and uses best available science and technology such as research, modeling, experimentation, monitoring and evaluation to address uncertainties.
