This research theme facilitates the sound management and restoration of Pacific Northwest Douglas-fir forests, as well as to refine broader-scale predictions of how temperate forests will function in an increasingly nitrogen-rich world.
This research theme examines the impacts of prescribed fire on plant productivity, soil physical, chemical, and biological characteristics, and nutrient leaching. Results from this research will enable improved decision-making of how to manage fire-prone forests to maintain long-term forest fertility and productivity, especially across wide climate gradients characteristic of the Pacific...
This research theme coalesces studies of old-growth temperate forests in several major thematic areas including landscape and ecosystem controls on watershed nutrient export, wildfire disturbance legacies on biogeochemical cycling, and the imprint of tree species on soil nutrients in old-growth forests.
The Hunt For The Southernmost Snakehead. Thirty-one fishery biologists from eleven agencies participated in a two-day Fish Slam event. Thirty-five sites in Broward and Miami-Dade counties were sampled for non-native fishes.
Find out more about invasive species in the Everglades such as the burmese python and black and white tegus.
Find out more about invasive species in the Pacific islands such as brown treesnake, invasive mammals (mouflon, feral pigs, rats, and mongoose), plants, ants, and yellowjacket wasps.
Find out more about invasive species in the western U.S. such as cheatgrass, tamarisk, and buffelgrass.
USGS research focuses on developing and enhancing capabilities to forecast and predict invasive species establishment and spread. Early detection helps resource managers identify and report new invasive species, especially for cryptic species and those in very low abundance, to better assess risks to natural areas.
Tracking the establishment and spread of existing and new invasive species is critical to effectively manage invasive species.
Find out more about invasive species in the midwest such as asian carp, sea lamprey, and phragmites.
The USGS develops strategies and techniques to understand and facilitate restoration of native species and habitats affected by invasive species. This is critical because control without restoration can leave the ecosystem vulnerable to subsequent reinvasion by the same or additional invasive species.

The influence of a severe reservoir drawdown on springtime zooplankton and larval fish assemblages in Red Willow Reservoir, Nebraska
Reservoirs can be dynamic systems, often prone to unpredictable and extreme water-level fluctuations, and can be environments where survival is difficult for zooplankton and larval fish. Although numerous studies have examined the effects of extreme reservoir drawdown on water quality, few have examined extreme drawdown on both abiotic and biotic...DeBoer, Jason A.; Webber, Christa M.; Dixon, Taylor A.; Pope, Kevin L.
Postnatal growth rates covary weakly with embryonic development rates and do not explain adult mortality probability among songbirds on four continents
Growth and development rates may result from genetic programming of intrinsic processes that yield correlated rates between life stages. These intrinsic rates are thought to affect adult mortality probability and longevity. However, if proximate extrinsic factors (e.g., temperature, food) influence development rates differently between stages and...Martin, Thomas E.; Oteyza, Juan C.; Mitchell, Adam E.; Potticary, Ahva L.; Lloyd, P.
Optimizing surveillance for South American origin influenza A viruses along the United States Gulf Coast through genomic characterization of isolates from blue-winged teal (Anas discors)
