Geographic location of data collection (where was data collected?): northeastern Minnesota, USA, in and around Grand Portage Indian Reservation 5. Information about funding sources that supported the collection of the data: Minnesota Environment and Natural Resources Trust Fund, as recommended by the Legislative-Citizen Commission on Minnesota Resources US Fish and Wildlife Services Tribal Wildlife Grant Program U.S. Bureau of Indian Affairs U.S. EPA Great Lakes Restoration Initiative Minnesota Zoo Ulysses S. Seal Conservation Fund Indianapolis Zoo Conservation Grant Van Sloun Foundation -------------------------- SHARING/ACCESS INFORMATION -------------------------- 1. Licenses/restrictions placed on the data: This research leveraged data gained from a long-term ecosystem health research program led by the Grand Portage Band of Lake Superior Chippewa (GPBLSC) and University of Minnesota. The GPBLSC is a federally recognized Indian tribe in extreme northeastern Minnesota and proudly exercises its rights to food sovereignty through subsistence hunting and fishing. Moose and deer are primary subsistence food used by the Anishinaabeg (people) of Grand Portage Band historically and presently and thus sets the context for this paper examining the impact of predators on disease transmission between the two cervid species. The GPBLSC is a sovereign indigenous nation that owns the data used in this manuscript. Those data are protected under the principles of data sovereignty: see T. Kukutai, J. Taylor, Indigenous Data Sovereignty: Toward an agenda (ANU Press, 2016; https://library.oapen.org/handle/20.500.12657/31875) and are shared under a data sharing and ownership agreement with the University of Minnesota for analysis and publication of scientific products: see Moore, Seth A; Wolf, Tiffany M; Travis, Dominic A. (2015). Data Sharing and Ownership Agreement for the Research Project “Building a One Health Research Collaboration between UMN and Grand Portage Indian Reservation” between the Grand Portage Band and the Regents of the University of Minnesota, on behalf of its College of Veterinary Medicine, Department of Veterinary Population Medicine. Retrieved from the University of Minnesota Digital Conservancy, https://hdl.handle.net/11299/213279). The Grand Portage Band has invested heavily in the acquisition of these important and sensitive data for the good of the Tribe. In maintaining ownership of these data, the Band ensures that any future western scientific products that emerge from these data integrate and reflect the cultural priorities of the Band. The Grand Portage Band is unwilling to make the original data publicly available as they show where culturally important and subsistence species occur on the reservation. In recognizing the spirit of the intent for others to be able to access the data independently and replicate the results presented in this manuscript or leverage the data for new scientific discoveries, the Band offers that interested parties may request permission through the Director of Biology and Environment Grand Portage Band of Lake Superior Chippewa (Dr. Seth Moore, samoore@boreal.org) to use the original data. Any entities that receive these data will be required to meet the terms of a data ownership and sharing agreement. We have provided simulated data of deer, moose, and wolf locations that can be used to replicate our analytical methods (see below for more detail). 2.

Description of methods used for collection/generation of data: Moose, white-tailed deer, and wolves were captured, handled, and fit with Global Positioning System (GPS) collars on the Grand Portage Indian Reservation in northeastern Minnesota, USA. Using the locations of these animals, we calculated how the species interact on the landscape in a way that caused 2 prey species (moose and deer) to spatially segregate under increased predation risk by wolves, thereby decreasing the risk of parasite transmission from deer to moose. For the csv files provided here ("deer_track.csv", "moose_track.csv", and "wolf_track.csv"), we simulated animal movement data as follows: We simulated random walking trajectories for each species (moose, deer, wolf) using its observed step length (SL) and turning angle (TA) distributions. Starting points were randomly sampled from minimum convex polygons calculated using all observed locations for each species. To simulate deer and moose dispersers and migraters, we also created trajectories taking into account two unique sets of SL and TA distributions. For example, for dispersers the trajectories were composed of three parts: random walking (sampled from original TA and SL), biased random walking (biased TA for some random angle to simulate a dispersing movement, and original SL), and another random walking (original TA and SL). For migraters, we have two additional parts: biased random walking (biased TA for the opposite angle sampled in second part for disperser [i.e., the return migration], and original SL), and another random walking (original TA and SL). Lastly, we created random noise (mean = 0, sd = 500) in the simulated locations for each simulated trajectory. Note that trajectories do not incorporate observed habitat selection coefficients, so the results using this dataset will not identically recreate the results found in the paper. This is to protect the data sovereignty of the Grand Portage Band of Lake Superior Chippewa and the sensitive nature of animal location data. This dataset aims to provide the reader the opportunity to reproduce each analytical step performed through the R code that we developed.
