Diel activity of newly metamorphosed juvenile sea lamprey in Carp River, MI 2011, Morpion Stream, Quebec 2014, and an artificial stream at Hammond Bay Biological Station 2014-2015 Diel activity of newly metamorphosed juvenile sea lamprey in Carp River, MI 2011, Morpion Stream, Quebec 2014, and an artificial stream at Hammond Bay Biological Station 2014-2015
These data contain biodata, net catch, and detection records for juvenile sea lamprey sampled in natural streams in Michigan and Quebec, Canada and those stocked into an artificial stream at the USGS Hammond Bay Biological Station for monitoring diel activity. During October 31 through November 9, 2011 scientists collected downstream migrating juvenile sea lamprey from the Little Carp...
River Channel Survey Data, Redwood Creek, California, 1953-2013 River Channel Survey Data, Redwood Creek, California, 1953-2013
Dr. Richard Janda of the USGS began a channel monitoring program in Redwood Creek in northern coastal California in 1973. The USGS continued this work through 2013, when the Research Geologist, Dr. Mary Madej retired. This effort produced 40 years of channel change data in rivers that were disrupted by severe erosion following timber harvest of old-growth redwood forests, a portion of...
Native and Invasive Species Plant Growth and Mortality in Growth Media Inoculated with Bacteria Found on Phragmites From New Jersey (2016) Native and Invasive Species Plant Growth and Mortality in Growth Media Inoculated with Bacteria Found on Phragmites From New Jersey (2016)
Bacteria were isolated from seeds of non-native Phragmites australis (haplotype M) then representatives were evaluated for their capacities to become intracellular in root cells, and their effects on: 1.) germination rates and seedling growth, 2.) susceptibility to damping-off disease, and 3.) mortality and growth of competitor plant seedlings (dandelion (Taraxacum officionale F. H. Wigg...
Lake Erie Collaborative Science and Monitoring Initiative 2014 Lake Erie Collaborative Science and Monitoring Initiative 2014
In 2014, the USGS Lake Erie Biological Station participated in the Coordinated Science and Monitoring Initiative (CMSI) program, a program founded by the U.S. Environmental Protection Agency (EPA) and Environment Canada in the 1990s as a means to focus collaborative research attention on one of the five Great Lakes each year (on a rotating schedule) as a means to increase scientific...
Lake Erie Fish Community Data, 2013-2017 Lake Erie Fish Community Data, 2013-2017
Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based based fishery management, and supports decision making that considers food-web interactions. In support of binational Great Lakes fishery management the objectives of this survey were to: provide estimates of densities of key forage and predator species in the...
Stable Isotopes of Silver Chub, Dreissenid mussels, and Hexagenia spp. Mayflies from Western Lake Erie, 2014 Stable Isotopes of Silver Chub, Dreissenid mussels, and Hexagenia spp. Mayflies from Western Lake Erie, 2014
This table contains Carbon and Nitrogen stable isotope data for Silver Chub (Macrhybopsis storeriana), dreissenid mussels, and Hexagenia spp. mayflies from western Lake Erie in 2014. Samples were collected between May and September 2014 as part of both routine monitoring and a lake-wide coordinated monitoring effort. Silver Chub were collected in trawls; Hexagenia and Dreissenids were...
Diets of Silver Chub (Macrhybopsis storeriana) in western Lake Erie, 2014 Diets of Silver Chub (Macrhybopsis storeriana) in western Lake Erie, 2014
Diet and estimated ages of Silver Chub (Macrhybopsis storeriana) collected by the US Geological Survey in western Lake Erie in 2014 are presented. Fish were frozen in the field at -20 C and dissected in the lab. Ages were estimated by one experienced biologist who estimated ages twice, then reconciled age estimates when the two age estimates differed. Diet taxa were enumerated, dried...
Magnetotelluric Data from the San Andreas Fault, Parkfield CA, 1990 Magnetotelluric Data from the San Andreas Fault, Parkfield CA, 1990
The U.S. Geological Survey (USGS) Geology, Geophysics and Geochemistry Science Center (GGGSC) collaborated with the USGS Data at Risk (DaR) team to preserve and release a subset of magnetotelluric data from the San Andreas Fault in Parkfield, California. The San Andreas Fault data were collected by the Branch of Geophysics, a precursor to the now GGGSC, between 1989 and 1994. The...
Cyanobacteria reduce quagga mussel spawning and fertilization success in laboratory bioassays Cyanobacteria reduce quagga mussel spawning and fertilization success in laboratory bioassays
Laboratory bioassays were conducted at Wayne State University in cooperation with USGS to determine if different species of cyanobacteria influence quagga mussel spawning and fertilization success. The data describes the algal cultures tested and their density/concentration, the number of individuals tested, and the spawning and fertilization success of quagga mussels exposed to the...
Quantitative polymerase chain reaction (qPCR): An alternative, rapid water quality monitoring tool at a National Park on Lake Michigan. Quantitative polymerase chain reaction (qPCR): An alternative, rapid water quality monitoring tool at a National Park on Lake Michigan.
Data were collected to evaluate the efficacy of quantitative polymerase chain reaction (qPCR) as a rapid, alternative method for monitoring recreational water at select beaches and rivers of Sleeping Bear Dunes National Lakeshore (SLBE), in Empire, Michigan. Water samples were collected between August 4 and September 18, 2014 (N=297) from four locations (Esch Rd, Otter Creek, Platte Bay...
Round goby eDNA survey, evaluation, and laboratory data in Lakes Michigan and Huron 2016-2017 Round goby eDNA survey, evaluation, and laboratory data in Lakes Michigan and Huron 2016-2017
Data included are from a series of field sample collections from Lakes Michigan and Huron, and laboratory mesocosms targeting the round goby fish (Neogobius melanostomus). The round goby is a benthic fish that has heavily invaded four of the five Laurentian Great Lakes. Because it inhabits a variety of substrates, including coastal breakwaters, traditional methods (e.g., trawling...
Water Depths and Velocities at Fish Egg Sampling Sites in the St. Clair-Detroit River System, 2005-2016 Water Depths and Velocities at Fish Egg Sampling Sites in the St. Clair-Detroit River System, 2005-2016
This dataset contains depths and bottom velocities at discreet sampling locations in the St. Clair-Detroit River System. Measurements were made to complement data on fish egg deposition in the St. Clair-Detroit Rivers from 2005-2016. Depth measurements were made with a boat mounted sonar unit at the beginning of spring and fall sampling season from 2005-2016. Water velocities near the...
