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

The Long Term Resource Monitoring (LTRM) program employs a destructive harvest method for sampling aquatic vegetation whereby a rake is dragged ~1.5 m over the substrate and plant materials are retrieved. The density of each species of submersed aquatic vegetation (SAV), and of all species combined, are scored based on the amount of plant material collected on the teeth of each rake. Plant density (PD) scores are ordered and vary from 0 (no plants captured) to 5 (80-100% of rake teeth covered). The PD score of 1 has represented the vast majority of all non-zero values since 1998 and is associated with a wide range of biomass (e.g. <1g to 694g fresh weight in Pools 4 and 8 during the 2017 field season). However,...
We sampled vegetation and breeding birds in Upper Mississippi River floodplain forest edge and interior areas to (1) measure Phalaris cover and (2) evaluate if the breeding bird assemblage responded to differences in Phalaris cover or other forest structure variables. Data are counts of birds collected during 3 surveys within 50m at each site using 10 minute point count methods. Vegetation was sampled using a releve technique at the bird count point within 10m of the point.

Breeding common loons for the movement and foraging pattern study were obtained from lakes in central and northern Minnesota and Wisconsin, and the Upper Peninsula of Michigan. Both adults of a territorial pair were fitted with archival geolocator tags (Model LAT 2500; 34.6 x 8.3 mm, 4.4 g; Lotek Wireless Inc.). A combination of adhesive and plastic cable ties were used to affix the geolocator tag to a modified lock-on aluminum leg band. Tags were programmed to collect daily location estimates for up to two years, tag temperature (0.02o C accuracy, ≤ 0.05o C resolution) at 30-min intervals, and pressure data (±1% accuracy, 0.05% resolution) at 20-sec intervals during daylight hours to document foraging patterns...

Detailed point center quarter sampling (Mueller-Dombois and Ellenberg 1974) was conducted during late June along a 150-m long transect that started at a bird survey point. Four plots were sampled corresponding to the start, 50m, 100m and end points of each transect. At each of these four sample plots, species, diameter at breast height (dbh) and distance from the center of the plot were recorded tor trees (>8cm dbh) and saplings (≤8cm dbh). Number of standing snags (>8cm dbh and over 2 m tall) within 25m of the plot center were counted. Total basal area of each plot was estimated using a size 10 angle gauge and averaged over the four plots in each transect. As well, height of a representative canopy tree and understory...

The Deepwater Horizon oil spill caused extensive injury to natural resources in the Gulf of Mexico, and Gavia immer (common loon) were negatively affected from the spill. The Open Ocean Trustee Implementation Group funded the project Restoration of Common Loons in Minnesota to restore common loons lost to the spill. In 2020–21, study lakes in an eight-county region in north-central Minnesota were identified to focus project activities. In 2021 and 2022, surveys were conducted on these lakes to monitor common loon territory occupancy, nest success, and chick survival. This dataset includes a summary of total number of artificial nesting platforms (ANP), total number of ANP and natural nests, ANP and natural nest...

The Hudson River, New York, was contaminated with polychlorinated biphenyls (PCBs) from two General Electric plants over a period of ~30 years and PCBs are still present in sediment and biota today. The river provides habitat for a variety of plants and animals, including native freshwater mussels. Although little is known about mussels in this river, managers were concerned that a 7-year remediation program to remove PCB-contaminated sediments could affect mussels. From 2013-2019, we conducted stratified (non-remediated, before remediation, after remediation) quantitative surveys across 17-pool-stratum combinations across nine pools. Sampling was done during August through October of each year. At each site, divers...

The data details common loon locations based on archival geolocator tag information, characteristics of common loon dives during wintering, and common loon locations based on telemetry data. Satellite transmitters (Model PTT-100, Microwave Telemetry, Inc) were implanted in 31 adult male (marked during July 2010 and July 2011) and 27 juvenile (marked during August 2014 and August 2015) common loons that were captured on breeding lakes in Minnesota, Wisconsin, and the Upper Peninsula of Michigan. The satellite transmitters were programmed to transmit on a variable schedule based on the anticipated stage of migration during the loon’s annual cycle. We utilized the most accurate locations per 8-hour transmission period...
