Climate-influenced phenology of larval fish transport in a large lake

Elucidating physical transport phenologies in large lakes can aid understanding of larval recruitment dynamics. Here, we integrate a series of climate, hydrodynamic, biogeochemical, and Lagrangian particle dispersion models to: (1) simulate hatch and transport of fish larvae throughout an illustrative large lake, (2) evaluate patterns of historic and potential future climate-induced larval transpo

Projected sea-level rise and high tide flooding at Timucuan Ecological and Historic Preserve, Florida

IntroductionNational parks and preserves in the South Atlantic-Gulf Region contain valuable coastal habitats such as tidal wetlands and mangrove forests, as well as irreplaceable historic buildings and archeological sites located in low-lying areas. These natural and cultural resources are vulnerable to accelerated sea-level rise and escalating high tide flooding events. Through a Natural Resource

Applying local and global sensitivity analysis to inform bigheaded carp management

Natural resource managers commonly use population-level models to aid in understanding the status of target populations or the potential implications of management actions. Sensitivity analyses, specifically, local sensitivity analysis (LSA) and global sensitivity analysis (GSA), exist as tools to improve understanding of these models, the importance of specific parameters to model outcomes, and t

Expanding Distribution of Chronic Wasting Disease

Chronic wasting disease (CWD) has been detected in 34 US states and five Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 34 states and four provinces and in captive cervid facilities in 19 states and three provinces.

USGS Science Opportunities Related to the Nationally Relevant Study of Microplastics

USGS recently (2024) released a strategic vision document that identifies science gaps and prioritizes research relevant to the mission, expertise, and capabilities of the USGS. The intention is for USGS and stakeholders to use this as a starting part for planning, prioritizing, and designing microplastic research projects.

Characterizing Post-Fire Burn Severity And Vegetation Recovery At High Spatial And Temporal Resolutions Using Basal Area Measurements

USGS scientists are studying the effects of wildfires on forests and developing models to predict forest recovery potential after fires. They have collected and analyzed data from several recent California wildfires, including the Dixie, Caldor, KNP Complex, Carr, and Mosquito fires. Researchers are using the data to analyze changes in basal area (the cross-sectional area of tree trunks) to...
