Plant data were collected on 16, 1-ha experimental blocks in C3 and Marsh Creek units of Seney National Wildlife Refuge, 2006-2010. The percent cover of each plant taxon, moss as a group, and open area was recorded sing a modified line-intercept method for each of 25 sampling points within a block. Sampling points were equidistantly spaced, with 5 points spaced 25 m apart along each of 5 transects also spaced 25 m apart within each sampling block. Within each unit, we selected 4 pairs of blocks representing sedge-shrub habitat, with one of the pair assigned to spring burning (C3, May 2008) or summer burning (Marsh Creek, 2007 and 2008). This before-after-control-impact design provided for data collection two growing...
These data were collected to estimate detection probability of Bombus affinis at known occupied sites in Wisconsin, Minnesota, Illinois, and Iowa in 2021. Data were also used to determine the effect of weather, observer experience, and habitat quality on Bombus affinis detection probability.

Exotic plant infestation is associated with decreased modularity and increased numbers of connectors in mixed-grass prairie pollination networks data set
This data set consists of data collected during 2012 in Badlands National Park in South Dakota that were used in the analysis in support of the PLOS One article titled "Exotic plant infestation is associated with decreased modularity and increased numbers of connectors in mixed-grass prairie pollination networks". The data consist of three spreadsheets. An insect richness, interactions, and flower count data set is a summary of counts of individual flowers (by species) and insects captured on flowers (that were found to carry pollen) over the course of a study on the effects of infestation by Cirsium arvense on pollinator interactions with native plants. Three dominant exotic plants, C. arvense, Convolvulus arvensis,...

In association with plant cover data, data on litter depth, water depth, and graminoid height were collected on 16, 1-ha experimental blocks in C3 and Marsh Creek units of Seney National Wildlife Refuge, 2006-2010. Within each unit, we selected 4 pairs of blocks representing sedge-shrub habitat, with one of the pair assigned to spring burning (C3, May 2008) or summer burning (Marsh Creek, 2007 and 2008). This before-after-control-impact design provided for data collection two growing seasons before the burn (2006, 16 blocks; 2007, 15 blocks) and two-three growing seasons (2008, 2009, and 2010; 14 blocks) after burning; the unburned plot of each pair served as the control, and the burned plot of each pair the treatment....

The Yellowknife Study Area (YSA),Northwest Territories, Canada, was established in 1961 by H. W. Murdy, U.S. Fish and Wildlife Service, for the study of wetland and waterfowl ecology. The study area is located on the western edge of the Precambrian Shield and edge of the taiga and is recognized for its high wetland densities and waterfowl abundance. The region is underlain by discontinuous, warm permafrost and hence vulnerable to a warming climate. The completion of Highway 3 in early 1960s provided the first access to the region for development, research, and monitoring. The YSA is a 38-square km area centered on Highway 3, extending 48 km in length. In the 1960s, it encompassed 262 natural ponds and 313 man-made...
