#Arctic wolf agent series

We found ARUs to be comparable to cameras in their detectability and occupancy of wolves, despite only operating for 3% of the time that cameras were active. In this study, we compared estimates of occupancy and detectability between ARUs and remote cameras for gray wolves (Canis lupus, Linnaeus 1758) in northern Alberta, Canada. In contrast, autonomous recording units (ARUs) record the sounds of animals with a much larger sampling area but are dependent on animals producing detectable vocalizations. However, drawbacks to camera traps include their limited sampling area and tendency for animals to notice the devices.

Statistical advancements in calculating population densities from camera trap data has increased the popularity of camera usage in mammal studies. Remote camera traps are often used in large mammal research and monitoring programs because they are cost-effective, allow for repeat surveys, and can be deployed for long time periods. Would help secure the future of the few remaining wolves on the island. A number of measuresДЄre proposed that, if implemented by the Greenland Home Rule Government, To exist, and dispersers reach north-east Greenland occasionally.

The resulting time series spans 40 years (1979вЂ“2018). Sightings of wolves by military ground patrols during winter and by others year-round. Three distributional core areas during three summers, 2012вЂ“14, and incidental Data sources comprised specialized wolf surveys in two of Greenland founded in 1979 and provides the first long-term information on the This study reports the disappearance of a small Arctic wolf population in north-east Wolves in the High Arctic may be particularly vulnerable because of their exceptionally low densities, smaller pack sizes, lower pup production, infrequent reproduction, and insular or disjunct distributions. This study provided the first evidence of an arctic wolf population that was eradicated and highlights the vulnerability of small, isolated wolf populations to excessive harvest. There was no evidence that other proposed causes of the decline were influential. Poison was the primary agent of destruction. The population was concentrated in the central part of its range, making it vulnerable to exploitation by Danish and Norwegian commercial hunters, who exterminated the population. Mean pack size was 3.3 wolves, and packs of more than four wolves were rare. Of 112 wolves sighted in early winter, 31.3% were lone wolves, 23.2% were in pairs, and the rest were in larger groups. Prior to the start of exploitation by Europeans, this small, isolated wolf population probably consisted of about 38 wolves during an average year.

The decline and extermination of an arctic wolf population in East Greenland between 18 were investigated through analysis of 40 years of archival data, which contained records of 252 sightings of wolves or their tracks.
