Benthic Community Dynamics in Coyote Creek and Artesian Slough, Southern San Francisco Bay, California, May 2016 to March 2018

Benthic invertebrate communities are monitored because the composition of those communities can affect and be affected by the water quality of an aquatic system. Benthic communities use and sometimes regulate the cycling of essential elements (for example, carbon). Benthic invertebrate taxa may also indicate acute and chronic stressors in an environment because they accumulate contaminants and can respond – sometimes dramatically - to oligotrophic and eutrophic conditions. Benthic communities affect water quality by grazing pelagic food resources and increasing the rate of nutrient regeneration through feeding and bioturbating sediments. South San Francisco Bay is a system dependent on phytoplankton as the base...

Nonindigenous aquatic species and potential spread after Hurricane Maria

This map was created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with Hurricane Maria. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of potential new species within a watershed. These data include a subset of data from the Nonindigenous Aquatic Species Database, that fall within the general area of the 2017...

Rainbow trout diet and invertebrate drift data from 2012-2015 for the Colorado River, Grand Canyon, Arizona

These data were compiled to explore the foraging ecology of Rainbow Trout (Oncorhynchus mykiss) in the Colorado River, Grand Canyon, Arizona. These data represent samples characterizing the availability of drifting invertebrate prey (hereafter, drift) and use of these invertebrate prey by rainbow trout determined by gut samples (hereafter, diets). Drift and diet sampling occurred in five distinct reaches downstream of Glen Canyon Dam (river kilometer (rkm) from the dam): (I) rkm 16.3-21.7; (II) rkm 52.8-58.3; (III) rkm 86.6-91.9; (IV) rkm 122.0-123.6; and (V) rkm 127.1-129.6. Samples were taken on 12 trips in April, July, September and January from April 2012 through January 2015. The aquatic prey base consists...

The Chesapeake Bay Multispecies Monitoring and Assessment Program (ChesMMAP)

In general, ChesMMAP is fishery-independent monitoring survey that uses a large-mesh bottom trawl to sample late juvenile-to-adult fishes in the mainstem of Chesapeake Bay. This program currently provides data on relative abundance, length, weight, sex ratio, maturity, age, and trophic interactions for several important fish species that inhabit the bay seasonally.

Sediment Biogeochemistry and Mercury Measurements from Wetlands of the San Francisco Bay, CA.

Habitat biogeochemistry was assessed by measuring 31 variables in sediments, porewater, and surface waters related to mercury content, organic matter, sediment characteristics, and microbial rates of sulfate reduction, iron reduction, and methanogenesis. Fifty-six composite surface (0-2 cm) sediment cores and 32 surface water samples were collected in three wetlands in the spring and summer of 2005 and 2006.

Sediment Biogeochemistry and Subsequent Mercury Biomagnification in Wetland Food Webs of the San Francisco Bay, CA (ver. 2.0, December 2023)

Methylmercury (MeHg) is a globally pervasive contaminant that biomagnifies in food webs and can reach toxic concentrations in consumers at higher trophic levels, including wildlife and humans. The production of MeHg, and its subsequent entry and biomagnification in food webs, is governed by a complex suite of biogeochemical, physical, and ecological processes, resulting in spatial variation in the distribution of MeHg. To better understand the link between MeHg production in sediments and MeHg bioaccumulation in biota, we evaluated the effects of habitat biogeochemistry, food web structure, and diet composition on bioaccumulation in the wetland-obligate California black rail (Laterallus jamaicensis coturniculus)...

Northeast Area Monitoring and Assessment Program Near Shore Trawl Survey (NEAMAP)

NEAMAP stands for NorthEast Area Monitoring and Assessment Program. NEAMAP was developed to meet the needs of fisheries management and stock assessment activities in the northeastern United States. NEAMAP began in 2006 with a fall pilot survey and in 2008 began conducting both a spring and fall survey. NEAMAP samples from Cape Cod, MA south to Cape Hatteras, NC and targets both juvenile and adult fishes. NEAMAP is an integrated, cooperative state/federal data collection program. Its mission is to facilitate the collection and dissemination of fishery-independent information obtained in the Northeast for use by state and federal fisheries management agencies, the fishing industry (commercial and recreational),...

Gulf of Mexico Habitat and Species Vulnerability

The Gulf Coast Vulnerability Assessment utilized expert opinion that was gathered through the Standardized Index of Vulnerability and Value (SIVVA) tool, which is an Excel-based vulnerability and prioritization tool that enables assessors to provide input in a relatively short time and allows for relatively seamless compilation of results.The vulnerability of each ecosystem and associated species was conducted by subregion, excluding those subregions where the species did not occur in significant numbers. Assessors were asked to evaluate species based on the habitats they use in a particular subregion. Because vulnerability can vary with life-stage for many species, assessors were asked to consider the most vulnerable...

Mercury Concentrations and Stable Isotope Ratios of Consumers from Different Subhabitats of Wetlands in the San Francisco Bay, CA

Primary and secondary consumers are important links in the trophic transfer of methylmercury, and their methylmercury concentrations are often measured to assess the potential risk of toxicity to higher trophic level consumers, including humans. A better understanding of the link between methylmercury production in sediments and methylmercury bioaccumulation in tidal marsh primary and secondary consumers will improve the design of contaminant monitoring, remediation, and restoration efforts, thereby protecting human and wildlife health. To advance this goal, we characterized spatial variation in sediment biogeochemistry and methylmercury concentrations of sediments, water, and consumer tissues at a meso-scale among...

Benthic community near the Palo Alto Regional Water Quality Control Plant in South San Francisco Bay (ver 2.0, November 2022)

Determining spatial distributions and temporal trends in trace metals in sediments and benthic organisms is common practice for monitoring environmental contamination. These data can be the basis for assessing metal exposure, the potential for adverse biological effects, and the response to regulatory or management actions (Suter, 2001). Another common method of environmental monitoring is to examine the community structure of sediment-dwelling benthic organisms (Simon, 2002). Spatial and temporal changes in community structure reflect the integrated response of resident species to environmental conditions, although the underlying cause(s) for the response may be difficult to identify and quantify. Together, measurements...
