Short Biography

Howard has diverse experience from wetland plants, aquatic invertebrates, fish, and wading birds.  He has studied these organisms from the estuaries of Apalachicola Bay, freshwater marshes of the Everglades, and streams of the Piedmont and Coastal Plain.  Although he specializes in fishes, he classifies himself as a general naturalist/ecologist.  How the dynamic environment structures biotic communities is his broad interest.  Imperiled freshwater fishes are his speciality, but nonindigenous and marine taxa are also studied.  For the past 16 years, he has been a leader of Okaloosa darter monitoring and recovery planning at Eglin Air Force Base in northwest Florida.  He has developed skills in sampling design, database development, geographical information system and statistical analyses.

My USGS Science Strategy Areas

Understanding Ecosystems & Predicting Ecosystems Change

Climate Variability & Change

Aquatic Diversity Conservation

The principal focus of my research is to increase our scientific understanding of the status of freshwater biological resources in North America and the factors that contribute to that condition.  Additional efforts are in marine biodiversity assessments and nonindigenous species interactions.  Special emphasis is on the southeastern United States, although some efforts are national and global in scale.

 

 

 

 

 

 


Imperiled Freshwater Organisms of North America

This website provides access to maps and lists of imperiled freshwater organisms of North America as determined by the American Fisheries Society (AFS) Endangered Species Committee (ESC). At this website, one can view lists of animals by freshwater ecoregion, by state or province boundary, and plot distributions of these same creatures by ecoregions or political boundaries.  http://fl.biology.usgs.gov/afs/index.html
