Synopsis: In an attempt to better characterize the influence of human settlement patterns on wolf distribution, this paper examined how radio-collared gray wolves responded to different road types and human presence at the boundaries of Kenai National Wildlife Refuge in south-central Alaska. Wolves tended to avoid oilfield access roads that were open to the public, but were attracted to gated pipeline access roads and secondary gravel roads with limited human use. The low use access and secondary roads likely provided an easy travel corridor for wolves. Prior to intensive trapping and hunting from 1978-1979, wolves demonstrated little territorial adjustment in response to a heavily used highway. However, only after...

Number of adult wolves and pups each year studied near Eureka, Ellesmere Island, Nunavut, Canada, 1987-2006
Cardiac chamber enlargement and hypertrophy are normal physiologic responses to repetitive endurance exercise activity in human beings and domestic dogs. Whether similar changes occur in wild animals as a consequence of increased activity is unknown. We found that free-ranging gray wolves (Canis lupus, n=11), the archetypical endurance athlete, have electrocardiographic evidence of cardiac chamber enlargement and hypertrophy relative to sedentary captive gray wolves (n=20), as demonstrated by significant increases in QRS duration, QT interval, and QT interval corrected for heart rate, a tendency towards increased Q, R, and S wave voltages in all leads, and a significant decrease in heart rate. We conclude that exercise...

The Commission on Environmental Cooperation, in concert with a trinational group of experts, has identified North American species of common conservation concern (SCCC). These terrestrial and marine species comprise a group of important migratory, transboundary and endemic species selected from among the continent’s great wealth of wild flora and fauna, which require regional cooperation for their effective conservation.
A Leslie matrix model was developed for a small gray wolf (Canis lupus) population recolonizing an area with abundant resources and uncontrolled by humans. The model was modified to describe population growth in a limited environment using a discrete form of the logistic equation. The density dependent Leslie matrix model was applied to investigate gray wolf population recovery in the Upper Peninsula of Michigan. Estimates from the density dependent matrix model were compared with published winter count estimates from the Michigan Department of Natural Resources. The gray wolf population in the Upper Peninsula of Michigan was projected to reach a total of 929 wolves by the year 2012 with a 95% confidence interval...

We developed and applied a simple population model to examine the relation between abundance of wolves in a wilderness area and the numbers that emigrate into adjacent agricultural areas and that may need to be removed on an annual basis. The model was applied using Minnesota wolf (Canis lupus) data. The gray wolf is emigrating from northern wilderness areas in the State of Minnesota (USA) into adjacent agricultural and urban areas to the south, and the costs of both wolf control and compensation to farmers for lost livestock is increasing as the number of wolves increases. Emigration reduces the number of wolves on a refuge to about 85% of the carrying capacity, and the number of wolves that emigrate into the agricultural...

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).
