Radio-collared wolves in the Superior National Forest that were killed by other wolves or probably killed by wolves between 1968 and 2014
Wolves (Canis lupus) and Canada Lynxes (Lynx canadensis) are on the Endangered Species List. Both inhabit pristine habitat in Minnesota, where it is possible and important to study their biology and interaction with their prey under natural conditions. These studies will allow managers and administrators to assess the progress of restoration and recovery of these species and anticipate biological and political problems that may arise during recovery. Most contentious is the issue of wolf interaction with their prey. Thus studies of wolf prey animals such as deer (Odocoileus virginianus), moose (Alces alces) and elk (Cervus elaphus) and the interactions of wolves with them are as important as investigatio [see Narratives...

The gray wolf (Canis lupus) in Minnesota, Wisconsin, and Michigan has been on and off the Endangered Species List since March 2007, and in late 2014 was placed back on because of legal technicalities, although biologically it is recovered there with > 4,000 wolves. The wolf has been restored to Yellowstone National Park and Montana and Idaho, is repopulating Oregon and Washington, and is being restored to Arizona and New Mexico. The federal government must continue monitoring wolf populations for 5 years post-delisting. By studying the long-term trend of an extant wolf population and its prey, scientists and managers can gain insights into the population and demographic trends that can be expected in restored populations....

Hematology and body mass were studied in nine female and five male free-ranging wolves in the Superior National Forest handled 4-17 times during 1989-1993. The dataset includes the following data for each wolf studied: wolf identifier, dates caught, sex, age, body mass in kg, adjusted body mass in kg, and values of hemoglobin (Hb), red blood cells (RBC), mean corpuscular hemoglobin (MCH), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), and white blood cells (WBC).
This dataset contains the capture location and summer location of deer radio-collared in the Garden Lake deeryard, near Ely MN during the summers of 1998, 1999, 2001, 2014, and 2017. The data set also contains the distance and direction deer migrated from capture locations to summer locations.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete.
