To ensure habitat restoration efforts are targeted towards areas maximizing monarch population growth, it is important to understand the effects of landscape heterogeneity on monarch occurrence in habitat patches (i.e. grasslands with milkweeds). Over two summers (2018-2019), monarch adults, larvae, and eggs were surveyed at sixty grassland sites in Wisconsin varying in patch size and landscape context. Milkweed density and floral richness were also estimated to characterize local patch quality. Results suggest that optimal sites for monarch habitat restoration are within landscapes with less surrounding habitat and that high milkweed density and floral richness should be conservation goals.

This data release consists of lakebed temperature data collected at the sediment-water interface at the north end of Haskell Lake, Lac du Flambeau Reservation, Wisconsin. Data were collected using a fiber-optic distributed temperature sensor (DTS) during a 5 day period from July 27 to August 1, 2016. Established procedures were followed to estimate lakebed temperatures from the raw DTS data and calibration baths of known temperatures. This data release includes the raw DTS (Stokes and anti-Stokes intensity) data, a shape file of the DTS cable location, photos from the field deployment, and python code for reproducing the full workflow described as part of U.S. Geological Survey Scientific Investigations Report 2020-5005....

These are data associated with water column incubation experiments performed in the Fox rivermouth. The Fox River is a Lake Michigan tributary that enters Green Bay. These experiments are used to measure the transformation of inorganic and total dissolved nutrients occurring in the surface water of the rivermouth. Experiments had light and dark treatments, and some experiments were paired with experiments where nutrients were increased in initial spikes. Ancillary data associated with the experiments such as photosyntheticly active radiation (PAR) and chlorophyll a content are also included. In addition to the data, there is R code used to generate the uptake rates and perform the analyses described in the associated...
