A site in north eastern MI, Oscoda Township, has some of the highest recorded exposure in birds to perfluorinated substances (PFASs) in the U.S. Some egg and plasma concentrations at that location exceeded the lowest reproductive effect threshold established for two avian laboratory species. The objectives of this study were to determine whether there were reproductive effects or physiological responses in a model bird species, the tree swallow (Tachycineta bicolor), associated with this extremely high exposure to PFASs. The lack of exposure above background to other contaminants at this site allowed for an assessment of PFAS effects without the complication that responses may be caused by other contaminants. A...
We applied Zequanox using a custom-engineered, boat mounted application system to replicated 0.30 Hectare plots within a small inland lake. The objectives of these applications were to determine if uncontained, open-water Zequanox applications could effectively control zebra mussel populations and protect native unionid mussel populations within zebra mussel infested systems. The datasets included are as follows: Exposure Water Chemistry Hardness and Alkalinity Native Mussel Sonde Water Chemistry Zebra Mussel Density Zebra Mussel Length Zebra Mussel Mortality Zequanox Concentration ShapeFiles: PLOTS, UNIONID, ZEQUANOX CONCENTRATION, ZM_DENSITY, ZM_MORTALITY

Invasive species may vary in their seasonal distribution and abundance due to environmental conditions such as precipitation and temperature. Bigheaded carps, which include silver and bighead carp, are one such taxon of invasive species that appear to change habitats seasonally. Seasonal changes in bigheaded carp distribution may occur because of hydrological changes, water temperature changes, and spawning activities. Monitoring this seasonal dispersal and migration is important for management to control the population size and spread of the species. We examined if environmental DNA (eDNA) approaches could detect seasonal changes in the occurrence of DNA in water samples and used these approaches to calculate the...

To describe calling activity of Pseudacris crucifer in relation to temperature, precipitation, and wetland water levels, we programmed an acoustic recorder (Wildlife Acoustics) to sample seasonal amphibian calls remotely at study site SC4DAI2 in the St. Croix National Scenic Riverway from 2008 to 2012. We programmed the recorder to sample for five minutes at the top of every hour of every day from late winter/early spring through late summer. We used the Songscape option in Songscope software to generate annual summaries of all of our acoustic samples from SC4DAI2. These summaries included a median dB level for each prescribed frequency within each recording. Pseudacris crucifer, the spring peeper, inhabited SC4DAI2...
Since 2008, over 1,400 quadrats and about 2,500 mussels have been systematically sampled within West Newton Chute (WNC), contributing to a diverse assemblage of 25 live species, including 2 federally endangered species, and 10 Minnesota listed species. West Newton Chute is a 2.4 km long side channel in Navigation Pool 5 of the Upper Mississippi River and has an overall aquatic area of ~75 ha. The Minnesota Department of Natural Resources has been quantitatively sampling a mussel bed here (~650 meters long X 170 meters wide) annually since 2008. About 200 systematically-placed 0.25 m2 quads are sampled annually and the quads are spaced ~25 m apart. Briefly, divers excavate substrates to a depth of ~15 cm and place...

From 1994-1997 I surveyed breeding birds and sampled vegetation at 391 random points on UMR floodplain forest along a latitudinal gradient to characterize bird assemblages and associations with gradients in forest structure at the local survey point and land cover composition within 200m radius of survey points (landscape scale). We conducted 10 minute 50m fixed radius point counts (Ralph et al. 1993) to survey birds during the breeding period between 30 May and 10 July in all years. We sampled the southernmost pool (13) first and then progressed to each pool in succession northward, finishing in Pool 4, sampling each point once a season. Surveys were conducted from 30 minutes before to five hours after local sunrise....

Data set includes water Sr:Ca, Ba:Ca, and δ18O for the Upper Mississippi River and tributaries and otolith Sr:Ca, Ba:Ca, and δ18O data from bigheaded carp collected in pools 19-21 of the Upper Mississippi River. Abstract from manuscript: Knowledge of environments used during early life history and movement patterns of Bighead Carp (Hypophthalmichthys nobilis) and Silver Carp (H. molitrix), collectively termed bigheaded carps, in the Upper Mississippi River (UMR) would be valuable for informing control measures to limit further population expansion and impacts of these species. Lock and Dam 19 (LD19) is a high-head dam on the UMR that delineates downriver areas where bigheaded carps are well-established from upriver...
Transects in backwaters of Navigation Pools 4 and 8 of the Upper Mississippi River (UMR) were established in 1997 to measure sedimentation rates. Annual surveys were conducted from 1997-2002 and then some transects surveyed again in 2017-18. Changes and patterns observed were reported on in 2003 for the 1997-2002 data, and a report summarizing changes and patterns from 1997-2017 will be reported on at this time. Several variables are recorded each survey year and placed into an Excel spreadsheet. The spreadsheets are read with a SAS program to generate a SAS dataset used in SAS programs to determine rates, depth loss, and associations between depth and change through regression.

The sampling locations provided here were selected as a two-stage Generalized Random Tessellation Stratified (GRTS) sample (Stevens & Olsen 2004). The first stage of the GRTS draw used a master sample developed by the North American Bat Monitoring Program (Loeb et al. 2015) from a 10 x 10 km grid placed over the conterminous U.S., Canada, and Mexico. Each 10 x 10 km grid cell (hereafter, master cell) was assigned a GRTS rank by NABat. The rank represents the priority order in which master cells should ideally be sampled. For the second stage of the draw, sampling points within a master cell were selected. Each point was defined as a 30 x 30 m cell of the GIS raster that defined monarch-relevant habitat. Sampling...

This set of non-spatial tables provides a detailed link (crosswalk) between the general classification within Long Term Resource Monitoring (LTRM) land cover/use (LCU) geospatial layers and the U.S. National Vegetation Classification (USNVC), current as of April 2017. The Upper Mississippi River Restoration (UMRR) Program’s LTRM element has produced LCU data over the past three decades consisting of geospatial layers (maps) showing locations of vegetation and developed lands within the Upper Mississippi River System (UMRS). The LCU data layers contain a classification of 31 general classes specifically developed to meet needs and objectives of the LTRM element of the UMRR Program. Because the LTRM classification...

Invasion of North American waters by Dreissena polymorpha and D. rostriformis bugensis has resulted in declines in native North American Unionoida mussels. Dreissenid mussels biofoul unionid mussels in large numbers and interfere with unionid movement, acquisition of food and ability to open and close their shells. Initial expectations for the Great Lakes were that unionids would be extirpated where they co-occur with dreissenids, but recently adult and juvenile unionids have been found alive in several apparent refugia. These unionid populations may persist due to reduced dreissenid biofouling in these areas, and/or due to processes that remove biofoulers. For example, locations inaccessible to veligers may reduce...

During 2010-2014, tree swallow (Tachycineta bicolor) reproductive success was monitored at 68 sites across all 5 Great Lakes, including 58 sites located within Great Lakes Areas of concern (AOCs) and 10 non-AOCs. Sample eggs were collected from tree swallow clutches and analyzed for contaminants including polychlorinated biphenyls (PCBs), dioxin and furans, polybrominated diphenyl ethers, and 34 other organic compounds. Contaminant data were available for 360 of the 1249 clutches monitored. Markov chain multistate modeling was used to assess the importance of 5 ecological and 11 of the dominant contaminants in explaining the pattern of egg and nestling failure rates. Four of 5 ecological variables (female Age, Date...

Eggs were collected in the Upper Mississippi main stem (Pool 9 and Pool 11) during the summer of 2013. Using previously published morphological characteristics, eggs were positively identified as belonging to an invasive Asian carp genus. A subsample of these eggs was subsequently analyzed using molecular methods to determine species identity. Genetic identification of a total of 41 eggs was attempted using the cytochrome c oxidase 1 (COI) gene. Due to the preservation technique used (formalin) and resulting DNA degradation, sequences from only 17 individuals could be recovered. In all cases, non-carp cyprinids were identified as the most likely species identity (usually a Notropis spp.). In previously published...

This collection of conservation areas consists of the floodplain of the combined streams of the Iowa River and the Cedar River. The study area begins just southeast of Wapello, IA, and continues southeast until the Horseshoe Bend Division, Port Louisa NWR. The area is currently managed to maintain meadow or grassland habitat which requires intensive management due to vegetative succession. In addition, this floodplain area contains a high proportion of managed lands and private lands in the Wetland Reserve Program and is a high priority area for cooperative conservation actions. This project provides a late-summer baseline vegetation inventory to assess future management actions in an adaptive process. Changes in...

Implantable satellite transmitters (e.g., Model PTT-100, Microwave Telemetry, Inc) were incorporated into the study to provide fine-resolution location data for a sample of the adult male common loons fitted with geolocator tags in 2010 and 2011. Transmitters were implanted in the abdominal cavity following procedures developed by Korschgen et al. (1996). The satellite transmitters were programmed to transmit on a variable schedule based on the anticipated stage of migration during the loon’s annual cycle - 8 hours on:72 hours off during the breeding season, 8 hours on:24 hours off while migrating, 6 to 8 hours on:96 hours off on the wintering grounds, and 8 hours on:24 hours off during spring migration, and 8 hours...
Three sets of standardized land cover/use data exist (1989, 2000, and 2010) for the Upper Mississippi River System (UMRS) through the US Army Corps of Engineers (USACE), Upper Mississippi River Restoration (UMRR) program. These data provide the opportunity to detect planform change for two time periods: 1989-2000 and 2000-2010. This dataset identifies specific types of changes and addresses errors from potential sources in the overlay. Four of the change types will be reported on, while the others change types were retained in the derived data.
