Conservation, Quantitative, and Restoration Ecology

Conservation Ecology scientists support resource management agencies through lab and field studies that evaluate contamination, behavior, invasive species, fire, the persistence and fate of land management chemicals, and the causality of species and/or population declines with an emphasis on threatened or endangered species.    

Restoration Ecology scientists develop methods for evaluating the success of ecological restoration with an emphasis on monitoring ecosystem structure and function.  Much of the effort is in support of the DOI's Natural Resource Damage Assessment and Restoration Program and directed toward restoration in contaminated habitats.  The methods developed are intended to help resource managers ensure restoration activities lead to the recovery of ecosystem services.

Qualitative Ecology scientists conduct risk assessments to understand the potential spread of invasive species, and habitat characteristics that may influence their distribution.  They also conduct population and energetic modeling to understand habitat requirements of species at risk such as the pallid sturgeon.

Use and Evaluation of Stimuli for Herding Bigheaded Carps to Increase their Capture Efficiency

Mass removal of the invasive silver carp Hypophthalmichthys molitrix and bighead carp Hypophthalmichthys nobilis (collectively referred to as bigheaded carp) is a primary management action in the United States to contain population growth and reduce upstream dispersal. Efficient capture and removal techniques are required to achieve this goal, and the USGS is working to develop and evaluate such...

Development and Evaluation of Novel Capture Gears for Bigheaded Carps

Mass removal of Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis , hereafter referred to as bigheaded carps, is a primary management action to contain the population growth and reduce upstream dispersal. The use of passive trap nets to harvest bigheaded carps may effectively supplement active capture techniques. The USGS is working with partner agencies to...

Chemical Attractant Investigations to Increase Aggregation and Harvest for the Control of Asian Carp

Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis , hereafter referred to as bigheaded carps, are rapidly expanding their range. Federal agencies and the Illinois Department of Natural Resources are focused on keeping invasive carps out of the Great Lakes. The development of an effective attractant may assist managers with capturing carps in low-density areas such...

Assessment of Acoustic Stimuli for Manipulating Movement of Bigheaded Carps

Invasive Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis , hereafter referred to as bigheaded carps, have displayed a negative phonotactic response when presented with a broadband acoustic stimulus. Additional study is needed to identify effective acoustic stimuli for manipulating bigheaded carp behavior, and to test bigheaded carp responses to those stimuli in...

High Resolution Vegetation Mapping at Palmyra Atoll Using Unoccupied Aerial Systems (UAS)-Acquired Imagery

Lying 1000 miles south of Hawaii, Palmyra Atoll is a marine wilderness co-managed by the US Fish and Wildlife Service and The Nature Conservancy. Beach forests of Pisonia grandis and other vegetation communities provide habitat for thousands of nesting terns, boobies, and other birds. Introduced coconut ( Cocos nucifera ) groves and use of Palmyra as a World War II airfield left a legacy of...
