Abstract Human activity and land use change impact every landscape on Earth, driving declines in many animal species while benefiting others. Species ecological life history traits may predict success human‐dominated landscapes such that only with “winning” combinations of will persist disturbed environments. However, this link between successful coexistence humans remains obscured by the complexity anthropogenic disturbances variability among study systems. We compiled detection data for 24...
In 2003–2004, we examined 8031 whitebark pine ( Pinus albicaulis Engelm.) trees and 3812 seedling-establishment sites in 170 plots for mortality incidence of white blister rust Cronartium ribicola A. Dietr.). We found all but four (98%), 57% assessed were either already dead or showed signs infection. Mean percentage infected was highest the southern Canada – United States border area (∼73%), decreasing to a low northern region Banff National Park, Alberta (∼16%), then rising (∼60%) end...
Species' distributions are influenced by a combination of landscape variables and biotic interactions with other species, including people. Grizzly bears black sympatric, competing omnivores that also share habitats human recreationists. By adapting models for multi-species occupancy analysis, we analyzed trail camera data from 192 locations in around Jasper National Park, Canada to estimate grizzly bear occurrence intensity use. We documented (a) relative habitat (b) use species motorised...
Whitebark pine (Pinus albicaulis Engelm.), a keystone species in subalpine ecosystems of western North America, is under threat across its range from white blister rust, mountain beetle, fire exclusion, and climate change. Loss whitebark predicted to have cascading effects on many ecosystem services. We remeasured 115 plots the Canadian Rocky Mountains determine whether infection mortality rates rust were changing over time (or) latitude. Average trees among increased 42% 2003–2004 52% 2009,...
Corridor restoration is increasingly being used to connect habitat in mountainous areas where rugged topography and increasing human activity fragment habitat.Wolves (Canis lupus) are a conservation priority because they avoid with high levels of use ecologically important predators.We examined how corridor through golf course changes the distribution wolves their prey Jasper National Park, Alberta, Canada.We followed recorded wolf paths snow both within surrounding landscape before after...
Whitebark pine forests are declining due to infection by white blister rust and mountain beetle, combined with the effects of climate change fire suppression. The Canadian Rocky Columbia Mountains represent a large portion whitebark range; vast area, exemplifying need for knowledge about stands target restoration. aim our work was identify variables predicting live tree infection, seedling canopy kill, mortality, regeneration across this region, present results in spatially-explicit formats...
Based upon the lessons learned and educational materials generated from a doctoral course on qualitative data analysis, group of students, their professor, linguistics consultant launched an on- going project to create series reusable learning objects designed help other groups students professors learn how analyze data. The results first six months this are shared, as team describes they have begun use instructional design software applications digital environment in form activities...
Abstract Global populations of wildlife are affected by human activity, land cover change, and climate change. Long‐term monitoring programs across large spatial scales required to understand how these other factors affect populations. Occupancy models frequently used monitor changes in species distribution while accounting for imperfect detection. surveys can be expensive because they typically require multiple estimate the probability Time‐to‐detection provide a promising approach...
Harlequin Duck (Histrionicus histrionicus) is a small sea duck that winters in coastal waters and breeds on fast-movingmountain streams western North America. Because of its dependency near-shore habitat with healthy macroinvertebrate populations, population trends this species can be used as an indication freshwater marine ecosystems. From 1995 to 2020 we conducted roadside surveys for Ducks the Bow River Banff National Park, Alberta. We calculated population’s trend by modelling maximum...
Limber pine (LP, Pinus flexilis) and whitebark (WBP, albicaulis) are classified as endangered in Canada due to rapid declines caused by the introduced pathogen causing white blister rust (WPBR, Cronartium ribicola), mountain beetle, other stressors. A monitoring study from 2003–2019 on 102 LP 232 WBP permanent plots found that mortality decreased with increasing latitude spring solar radiation, while was highest at low latitudes elevations areas higher moisture longer growing degree days....
This is the first study testing effectiveness of semiochemical treatments to protect individual trees from a range-expanding mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins, 1902) attack into newly exposed host populations endangered whitebark (Pinus albicaulis Engelm.). We investigated combination verbenone and green-leaf volatiles (GLV) rare valuable disease-resistant during MPB epidemic 2015 2018 in Jasper National Park, Canada. Treatments reduced proportion attacked by for all...
