Estimating peak-flow quantiles for selected annual exceedance probabilities in Illinois Estimating peak-flow quantiles for selected annual exceedance probabilities in Illinois
This report presents the methods, results, and applications of an updated flood-frequency study for the State of Illinois. This study, which uses data through September 2017, updates two previous studies that used data through 1999 and 2009, respectively. Flood-frequency estimates are used for a variety of land-use planning and infrastructure design purposes, including for the hydraulic...

The consequences of neglecting reservoir storage in national-scale hydrologic models: An appraisal of key streamflow statistics The consequences of neglecting reservoir storage in national-scale hydrologic models: An appraisal of key streamflow statistics
A better understanding of modeled streamflow errors related to basin reservoir storage is needed for large regions, which normally have many ungaged basins with reservoirs. We quantified the difference between modeled and observed streamflows for one process-based and three statistical-transfer hydrologic models, none of which explicitly accounted for reservoir storage. Streamflow...

Mapping stream and floodplain geomorphometry with the Floodplain and Channel Evaluation Tool Mapping stream and floodplain geomorphometry with the Floodplain and Channel Evaluation Tool
Broad-scale mapping of stream channel and floodplain geomorphic metrics is critical to improve the understanding of geomorphic change, biogeochemical processes, riverine habitat quality, and opportunities for management intervention. The Floodplain and Channel Evaluation Tool (FACET) was developed to provide an open-source tool for automated processing of digital elevation models (DEMs)...

Survival and growth of juvenile mussels in an outdoor pond after 28-day laboratory exposure to aqueous zinc Survival and growth of juvenile mussels in an outdoor pond after 28-day laboratory exposure to aqueous zinc
The extent to which effects seen in chronic toxicity studies in the laboratory affect mussel fitness later in life is poorly known. We examined juvenile Fatmucket (Lampsilis siliquoidea) survival and growth for 56 d following exposure to Zn in a laboratory bioassay. We conducted a 28-d chronic toxicity bioassay with 6-wk-old juvenile mussels exposed to a control and two Zn treatments...

CGS: Coupled growth and survival model with cohort fairness CGS: Coupled growth and survival model with cohort fairness
Fish modeling in complex environments is critical for understanding drivers of population dynamics in aquatic systems. This paper proposes a Bayesian network method for modeling fish survival and growth over multiple connected rivers. Traditional fish survival models capture the effect of multiple environmental drivers (e.g., stream temperature, stream flow) by adding different variables...

Confirmation of significant sea turtle nesting activity on a remote island chain in the Gulf of Mexico Confirmation of significant sea turtle nesting activity on a remote island chain in the Gulf of Mexico
Globally, six of the seven sea turtle species are threatened or endangered and as such, monitoring reproductive activity for these species is necessary for effective population recovery. Remote beaches provide a challenge to conducting these surveys, which often results in data gaps that can hamper management planning. Throughout the summer of 2022, aerial surveys were conducted over the

Genetic analysis of federally endangered Cape Sable seaside sparrow subpopulations in the Greater Everglades, USA Genetic analysis of federally endangered Cape Sable seaside sparrow subpopulations in the Greater Everglades, USA
The federally endangered Cape Sable seaside sparrow (Ammospiza maritima mirabilis) is endemic to the Greater Everglades ecosystem in southern Florida, inhabiting fragmented marl prairies in six individual subpopulations. The subspecies is threatened by loss of breeding habitat from fire and water management. Genetic information is severely limited for the subspecies but could help inform...

A global biodiversity observing system to unite monitoring and guide action A global biodiversity observing system to unite monitoring and guide action
The rate and extent of global biodiversity change is surpassing our ability to measure, monitor and forecast trends. We propose an interconnected worldwide system of observation networks — a global biodiversity observing system (GBiOS) — to coordinate monitoring worldwide and inform action to reach international biodiversity targets.

Parameter estimation at the conterminous United States scale and streamflow routing enhancements for the National Hydrologic Model infrastructure application of the Precipitation-Runoff Modeling System (NHM-PRMS) Parameter estimation at the conterminous United States scale and streamflow routing enhancements for the National Hydrologic Model infrastructure application of the Precipitation-Runoff Modeling System (NHM-PRMS)
This report documents a three-part continental-scale calibration procedure and a new streamflow routing algorithm using the U.S. Geological Survey National Hydrologic Model (NHM) infrastructure along with an application of the Precipitation-Runoff Modeling System (PRMS). The traditional approach to hydrologic model calibration and evaluation, which relies on comparing observed and...

Investigating microbial size classes associated with the transmission of stony coral tissue loss disease (SCTLD) Investigating microbial size classes associated with the transmission of stony coral tissue loss disease (SCTLD)
Effective treatment and prevention of any disease necessitates knowledge of the causative agent, yet the causative agents of most coral diseases remain unknown, in part due to the difficulty of distinguishing the pathogenic microbe(s) among the complex microbial backdrop of coral hosts. Stony coral tissue loss disease (SCTLD) is a particularly destructive disease of unknown etiology...

A Monte-Carlo chemical budget approach to assess ambient groundwater flow in bedrock open boreholes A Monte-Carlo chemical budget approach to assess ambient groundwater flow in bedrock open boreholes
In low-permeability rocks, ambient groundwater flow in open boreholes may go undetected using conventional borehole-flowmeter tools and alternative approaches may be needed to identify flow. Understanding ambient flow in open boreholes is important for tracking of cross contamination in groundwater. Chlorinated volatile organic compound (CVOC) concentrations from three open boreholes set...
