Wolf noninvasive methods trial from 2019-2021 in the Superior National Forest metadata
This dataset contains gray wolf (Canis lupus) study area section counts of pack wolves by method (observing radiocollared wolves and their packmates via aerial telemetry and also noninvasive methods including ground snow tracking, aerial snow tracking, camera trapping, community scientist reports) from a three winter noninvasive methods trial during 2019-2021 in the USGS Wolf Project...
Wolf survival and cause-specific mortality from 1968-2018 in the Superior National Forest. In
This dataset contains gray wolf (Canis lupus) survival and cause-specific mortality data from radiocollared wolves (n=756 collared-wolf tenures) from 1968-2018 in the USGS Wolf Project study area (2,060 km2) of the Superior National Forest, USA, an area that also includes the Boundary Waters Canoe Area Wilderness. Also, included are the annual resident winter wolf counts for the study...
Garden Lake Deer Yard (Lake Co., MN) Migration Data, 1998-2017
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.

Automatic recorders monitor wolves at rendezvous sites: do wolves adjust howling to live near humans?
We used automatic sound recorders to study spontaneous vocalizations of wild wolves during the pup-rearing season around rendezvous sites from 24 wolf packs in six study areas across North America, Asia, and Europe. Between 2018 and 2021, for a total of 1225 pack-days, we recorded 605 spontaneous wolf chorus howls and 224 solo-howl series. Howling occurrence varied across areas, from 12...

Can non-invasive methods replace radiocollar-based winter counts in a 50-year wolf study? Lessons learned from a three-winter trial
Context: Monitoring low-density, elusive predators such as grey wolves (Canis lupus) has often been undertaken via live-capture and radio-collaring. Recent advances in non-invasive methods suggest live-captures may not be necessary for adequate monitoring. Further, non-invasive methods are considered best practice when possible.Aims: I evaluated whether a suite of non-invasive methods...

Are wild wolves southpaws? Including potential conservation implications
Lateralization, or a left-right bias in behavior (e.g., handedness), was originally thought to exclusively exist in humans, but is now known to be widespread. Lateralization can exist at the individual or group level. In dogs (Canis lupus familiaris), tests of paw preference have produced inconsistent results. Because wolves (C. l.) differ genetically, morphologically, and behaviorally...

Assessing spontaneous howling rates in captive wolves using automatic passive recorders
We studied the spontaneous vocal behaviour of captive wolves at the International Wolf Center (IWC) in Minnesota (spring 2019 and winter 2020), and the Centro del Lobo Ibérico Félix Rodríguez de la Fuente (CLIFRF) in Spain (winter 2020). We used AudioMoth recording devices to record wolf howling 24 hr/day. We identified 412 solo howl series and 403 chorus howls and found differences...

Acoustic interaction between a pair of owls and a wolf
During summer 2019, we recorded an apparent vocal interaction, lasting just under 4 min, between a pair of Great Horned Owls (Bubo virginianus) and a gray wolf (Canis lupus) in Yellowstone National Park. To our knowledge, this is the first report of such an acoustic interaction in the scientific literature. The increased use of passive acoustic recorders, which record spontaneous...

Ambassador wolves participate In scientific research
The International Wolf Center wolves are famous for providing unique educational opportunities to visitors to Ely and to people around the globe. Less known, are the contributions these wolves make to scientific research. Recently the Center’s Exhibit Pack were subjects of behavioral and acoustic research.

Be a wolf researcher! Wolf pup ethogram
Ethology is the study of behavior, and an ethogram is a list of behaviors, typically of a single species. For this ethogram we have selected a few representative behaviors that pups will exhibit during various growth phases, and therefore, this ethogram is not exhaustive. You will likely observe behaviors not detailed in this booklet (be sure to keep notes of your observations on the...

The importance of wilderness to wolf (Canis lupus) survival and cause-specific mortality over 50 years
We assessed the relative importance of wilderness to gray wolf (Canis lupus) population dynamics over 50 years in a population that 1) was long extant (i.e., not reintroduced or recolonized), 2) was not subject to harvest in our study area until recently, and 3) used both wilderness and adjacent, mainly public, non-wilderness. We analyzed the survival of radiocollared wolves (n = 756...

Patterns and processes of pathogen exposure in gray wolves across North America
The presence of many pathogens varies in a predictable manner with latitude, with infections decreasing from the equator towards the poles. We investigated the geographic trends of pathogens infecting a widely distributed carnivore: the gray wolf (Canis lupus). Specifically, we investigated which variables best explain and predict geographic trends in seroprevalence across North American...

Historic population estimates for bottlenose dolphins (Tursiops truncatus) in Aragua, Venezuela indicate monitoring need
This study reports historic capture-mark-recapture survival and abundance estimates of common bottlenose dolphins (Tursiops truncatus) based on photo-identification surveys of coastal Venezuela (along the Aragua coast between Turiamo Bay and Puerto Colombia). We used the most recent data available: dolphins identified by unique dorsal fin marks during wet and dry season surveys conducted...
