Workshops report for mesophotic and deep benthic community fish, mobile invertebrates, sessile invertebrates and infauna Workshops report for mesophotic and deep benthic community fish, mobile invertebrates, sessile invertebrates and infauna
Two workshops with subject matter experts in the appropriate fields, were held in November and December 2021 to elicit guidance and feedback from the broader mesophotic and deep benthic scientific community. These workshops focused on best practices/approaches and identifying data gaps relative to habitat assessment and evaluation goals of the Mesophotic and Deep Benthic Community (MDBC)

Caretta caretta (Loggerhead Sea Turtle) nesting exchange Caretta caretta (Loggerhead Sea Turtle) nesting exchange
The Northwest Atlantic population of Loggerhead Sea Turtles (Caretta caretta) is one of the largest C. caretta populations in the world and is listed as threatened. This population was divided into five genetically distinct subpopulations, including the Northern Gulf of Mexico (NGoM) subpopulation (Shamblin et al. 2017 Mar. Bio. 164:138). Across the NGoM, the majority of C. caretta...

Identifying turbulence features hindering swimming capabilities of grass carp larvae (Ctenopharyngodon idella) through submerged vegetation Identifying turbulence features hindering swimming capabilities of grass carp larvae (Ctenopharyngodon idella) through submerged vegetation
Aquatic vegetation can provide habitat and refuge for a variety of species in streams. However, the flow features generated by submerged patches of vegetation can also pose a challenge for fish larvae. We conducted a series of experiments with live grass carp larvae (starting ∼50 h post hatch) in a laboratory racetrack flume, using a submerged array of rigid cylinders to mimic vegetation...

The use of dye-tracing studies to delineate the recharge area for Manitou Cave in northwestern Alabama The use of dye-tracing studies to delineate the recharge area for Manitou Cave in northwestern Alabama
In 2010 the U.S. Fish and Wildlife (USFWS) was petitioned to federally list the Manitou Cave Snail, (Antrorbis breweri ), a stygobiont endemic to Manitou Cave in northwestern Alabama. When an agency is tasked with determining whether to add a species to the Endangered Species List, one of the components examined is potential threats to the biota. Knowing the recharge area for a cave or...

Salinification of coastal wetlands and freshwater management to support resilience Salinification of coastal wetlands and freshwater management to support resilience
Climates are rapidly changing in wetland ecosystems around the world and historical land-use change is not always given enough consideration in climate adaptation discussions. Historical changes to hydrology and other key environments can exacerbate vegetation stress; e.g., recent drought and flood episodes are likely more extreme because of climate change. The contributions of global...

VIMTS: Variational-based Imputation for Multi-modal Time Series VIMTS: Variational-based Imputation for Multi-modal Time Series
Multi-modal time series data in real applications often contain data of different dimensionalities, e.g., high-dimensional modality such as image data series, and low-dimensional univariate time series. Multi-modal time series data with missing high-dimensional modal values are ubiquitous in real-world classification and regression applications. To accurately predict the target labels...

Food, beverage, and feedstock processing facility wastewater: A unique and underappreciated source of contaminants to U.S. streams Food, beverage, and feedstock processing facility wastewater: A unique and underappreciated source of contaminants to U.S. streams
Process wastewaters from food, beverage, and feedstock facilities, although regulated, are an under-investigated environmental contaminant source. Food process wastewaters (FPWWs) from 23 facilities in 17 U.S. states were sampled and documented for a plethora of chemical and microbial contaminants. Of the 576 analyzed organics, 184 (32%) were detected at least once, with concentrations...

Ambystoma opacum (marbled salamander). Atypical nest sites Ambystoma opacum (marbled salamander). Atypical nest sites
The discovery of inconspicuous nests in secretive species not only expands knowledge but can reveal previously unknown behaviors and ecological consequences of those behaviors. Marbled salamanders exhibit the unusual strategy of laying their eggs terrestrially under cover. Here we report multiple occurrences of A. opacum nesting inside logs, which may be atypical for this species.

Coastal and marine science of the U.S. Geological Survey in St. Petersburg, Florida Coastal and marine science of the U.S. Geological Survey in St. Petersburg, Florida
The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) in St. Petersburg, Florida, investigates processes that form and alter coastal and marine environments and the implications of these processes related to natural hazards, resource sustainability, and environmental change. The center is one of three facilities serving the mission of the USGS...

Emerging control strategies for integrated pest management of invasive carps Emerging control strategies for integrated pest management of invasive carps
Invasive carps are ecologically and economically problematic fish species in many large river basins in the United States and pose a threat to aquatic ecosystems throughout much of North America. Four species of invasive carps: black carp (Mylopharyngodon piceus), grass carp (Ctenopharyngodon idella), silver carp (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis)...

Evaluation of two existing flood management structures in U.S. Army Garrison Fort Gordon, Georgia, 2020 Evaluation of two existing flood management structures in U.S. Army Garrison Fort Gordon, Georgia, 2020
Two existing flood management structures in U.S. Army Garrison Fort Gordon, Georgia, were evaluated for potential retrofitting to address water-quality impacts, pursuant of U.S. Army Garrison Fort Gordon’s storm water management program. Stormwater calculations were computed according to the Georgia Stormwater Management Manual, including drainage area delineations, design-storm runoff...

Mapped predictions of manganese and arsenic in an alluvial aquifer using boosted regression trees Mapped predictions of manganese and arsenic in an alluvial aquifer using boosted regression trees
Manganese (Mn) concentrations and the probability of arsenic (As) exceeding the drinking-water standard of 10 μg/L were predicted in the Mississippi River Valley alluvial aquifer (MRVA) using boosted regression trees (BRT). BRT, a type of ensemble-tree machine-learning model, were created using predictor variables that affect Mn and As distribution in groundwater. These variables...
