Finally, the final map of movement corridors was reclassified into three categories, respectively, low, moderate and high to better represent the most important areas for C. lupus movements. (2017) Habitat suitability and movement corridors of grey wolf (Canis lupus) in Northern Pakistan. These varied climatic conditions and ecosystems support rare and endangered animals such as the snow leopard (Uncia uncia), brown bear (Ursus arctos), grey wolf (Canis lupus), Himalayan lynx (Lynx lynx), Marco Polo sheep (Ovis ammon polii), musk deer (Moschus chrysogaster), blue sheep (Pseudois nayaur), Himalayan Ibex (Capra ibex sibirica), flare-horned markhor (C. f. cashmirensis), Ladakh urial (Ovis orientalis vignei) and woolly flying squirrel (Eupetaurus cinereus). The MODIS normalized difference vegetation index product is computed from atmospherically corrected bi-directional surface reflectance that have been masked for water, clouds, heavy aerosols and cloud shadows. This study used information from research compiled on existing wolf packs in the contiguous United States, along with management and reintroduction plans to locate suitable land for gray wolves located in the state of Pennsylvania. No, Is the Subject Area "Roads" applicable to this article? Wolves that leave their packs are known to have traveled as far as 886 km (550 miles). They obtain most of their liquids through their food. Commercial trapping scent lures were deployed in some randomly selected sites . The binary map discriminated between areas typically used by wolves and those considered unsuitable (Fig 4). Wolf populations in the Hindu Kush appear to be well connected with the population of the Pamirs and Karakorum’s, which is also enhanced by the establishment of PAs, including the Broghil, Qurumber and Khunjerab National Parks. After making a kill, the pack gorges (consuming some 3 to 9 kg [7 to 20 pounds] per animal) and then lingers, often reducing the carcass to hair and a few bones before moving on to look for another meal. A spatial corridor model was developed using the distribution map of wolves in Circuitscape 4.0 software (http://www.circuitscape.org/downloads) . Gray wolves flourished to become the most widely dispersed land mammal on Earth, next to humans. Their range includes different habitats such as forest, arctic tundra, arid terrain and prairie. In order to provide comprehensive recommendations regarding the conservation of this species, potential habitat must … Dark blue bars = Importance of single variable, light blue bars = loss in model gain, when variable is omitted. Throughout spring and summer the pups are the centre of attention as well as the geographic focus of the pack’s activities. it contains the most information not present in other variables (Fig 5). Among the PAs, Chitral Gol, Broghil and Qurumber National Park had wide potential corridors comprised of suitable habitat connecting core areas. Grey wolves are able to travel through habitats considered poor in the search for an area to form a new pack . Animals use a wide variety of mechanisms to select suitable habitat and being aware of habitat use details is important for corridor design . Large packs seem to result from fewer young wolves’ leaving the group and from litters’ being produced by more than one female. The main predictors for habitat suitability for C. lupus were distances to road, mean temperature of the wettest quarter and distance to river. Fish and Wildlife Service protected gray wolves under the Endangered Species Act in 1978. The probability of wolf presence was 0.7 at 0 km2 of distance from the road and stream, but it drastically to 0.05 at a distance of 0.5 km2. Exceptions included habitat occupied by the eastern gray wolf, red wolf and Mexican wolf (Young and Goldman 1944; USFWS 2009a; USFWS 2011c). PLOS ONE promises fair, rigorous peer review, It shows how important each variable is in explaining wolf presence when used separately (cobalt blue), and how the model is affected when each variable is left out (aqua). Yes Wolf dispersal patterns across the landscape can better predict where new wolf populations may appear . The dataset was influenced by the species’ patchy distribution, its rarity throughout the landscape, its seasonal surface occurrence, and its location (when active) on steep and rocky (often impassable) terrain . The female predominates in roles such as care and defense of pups, whereas the male predominates in foraging and food provisioning and in travels associated with those activities. The most suitable areas identified from the models were located predominantly within PAs and most inaccessible areas with minimum human disturbance, and overall, mainly along the narrow valley and around summer livestock pastures. In addition, many people live and recreate in areas being considered for gray wolf habitat. We obtained 51 wolf presence records from camera traps and 80 from the genetic analysis of scat samples collected from the distribution range of wolves (Fig 2). Contrary to least cost resistance methods, Circuitscape does not assume that animals disperse according to previous knowledge of the surroundings, but is based on random walks . About 1,000 scat samples of carnivores were collected and preserved in 20 ml bottles filled with 95% alcohol. SDMs rely on presence-absence data or presence-only data [7, 9, 53–55]. In the setting panel, we selected the following options: auto features; random seed; write plot data; remove duplicate presence records; give visual warming; show tooltips; regularization multiplier (fixed at 1); 10,000 maximum number of background points; 1,000 maximum iterations; and, finally, we achieved a 20 replicates effect with cross-validation run type as suggested by Pearson et al. Funding: Main funding for this study came from the Research Council of Norway (Grant 204202/F20) and Snow Leopard Trust. Response curves derived from univariate models were plotted to know how each environmental variable influence presence probability. Gray wolves move and hunt mostly at night, especially in areas populated by humans and during warm weather. Grey wolves tend to occupy forests, tundra and grassy … Mean temperature of the wettest quarter ranged from -10°C to 10°C with a max value (0.6) of probability of presence around 0°C.

The wolf population in Deosai appears to be connected with the population of Central Karakorum National Park, but only weak connected with other potential habitat. Our editors will review what you’ve submitted and determine whether to revise the article. 2 ABSTRACT: For the first time since 1982, the United States Fish and Wildlife Service (FWS) is updating Mexican Gray Wolf Recovery Plan. Before going into the gray wolf's diet, we should offer a general overview of its physical characteristics and main traits. https://doi.org/10.1371/journal.pone.0187027.t001. It thus links populations through multiple pathways , such that connectivity between habitat patches increases according to the number of connected pathways, and the effective resistance between two populations is derived from the overall resistance across all pathways. https://doi.org/10.1371/journal.pone.0187027.g002.
