RESEARCH
Carla Wieser has been at the USGS Wetland and Aquatic Research Center since 1997 as a Fisheries Biologist working on contaminant issues in wildlife. Other duties at the Center include Environmental Management Systems (EMS) Coordinator, Environmental Program Coordinator (EPC), Chemical Hygiene Officer and Laboratory Manager.
BACKGROUND
A native to Nebraska, Wieser started her career working in zoological parks with large cats, great apes, elephants and the endangered black footed ferret (Mustela nigripes) and was part of the early reintroduction efforts of the black footed ferret.
Science and Products
Sperm quality biomarkers complement reproductive and endocrine parameters in investigating environmental contaminants in common carp (Cyprinus carpio) from the Lake Mead National Recreation Area
Lake Mead National Recreational Area (LMNRA) serves as critical habitat for several federally listed species and supplies water for municipal, domestic, and agricultural use in the Southwestern U.S. Contaminant sources and concentrations vary among the sub-basins within LMNRA. To investigate whether exposure to environmental contaminants is...

Patterns of metal composition and biological condition and their association in male common carp across an environmental contaminant gradient in Lake Mead National Recreation Area, Nevada and Arizona, USA
There is a contaminant gradient in Lake Mead National Recreation Area (LMNRA) that is partly driven by municipal and industrial runoff and wastewater inputs via Las Vegas Wash (LVW). Adult male common carp (Cyprinus carpio; 10 fish/site) were collected from LVW, Las Vegas Bay (receiving LVW flow), Overton Arm (OA, upstream reference), and Willow...

A comparison of mercury burdens between St. Marks National Wildlife Refuge and St. Andrew Bay, Florida: Evaluation of fish body burdens and physiological responses in largemouth bass, spotted seatrout, striped mullet, and sunfish
Musculature from the dorsal region of 130 largemouth bass (Micropterus salmoides), 140 sunfish (Lepomis sp.), 41 spotted seatrout (Cynoscion nebulosus) and 67 striped mullet (Mugil cephalus) were collected from five estuarine and five freshwater sites within the St. Marks National Wildlife Refuge and two estuarine and two freshwater sites from St...
Huge, D.H.; Rauschenberger, R.H.; Wieser, F.M.; Hemming, J.M. Chemical contaminants, health indicators, and reproductive biomarker responses in fish from rivers in the Southeastern United States
Largemouth bass (Micropterus salmoides) and common carp (Cyprinus carpio) were collected from 13 sites located in the Mobile (MRB), Apalachicola–Flint–Chattahoochee (ARB), Savannah (SRB), and Pee Dee (PRB) River Basins to document spatial trends in accumulative chemical contaminants, health indicators, and reproductive biomarkers. Organochlorine...

Biomonitoring of Environmental Status and Trends (BEST) Program: Environmental contaminants, health indicators, and reproductive biomarkers in fish from the Mobile, Apalachicola-Chattahoochee-Flint, Savannah, and Pee Dee River Basins
Largemouth bass (Micropterus salmoides) and common carp (Cyprinus carpio) were collected from 13 sites in 4 river basins in the southeastern United States to document spatial trends in accumulative contaminants, health indicators, and reproductive biomarkers. Organochlorine residues, 2,3,7,8- tetrachlorodibenzo-p-dioxin-like activity (TCDD-EQ),...

Reproductive and biochemical biomarkers in largemouth bass sampled downstream of a pulp and paper mill in Florida
The objective of this study was to evaluate the effects of bleached/unbleached kraft mill effluents (B/UKME) on the reproductive parameters of free-ranging Florida largemouth bass (Micropterus salmoides floridanus). The reproductive parameters measured included gonadosomatic index (GSI), histological evaluation of gonads, and plasma concentrations...

The annual reproductive cycle of hatchery-raised largemouth bass (Florida subspecies Micropterus salmoides floridanus) was characterized over a one-year period. Largemouth bass have a distinct annual reproductive cycle with a spring spawning season (approximately between mid-January and mid-June). Cycle characterization focused on an evaluation of...
