An appropriate conceptual leap can be made from human geography to physical geography by applying space‐time continuum modeling to zoogeomorphology—the alteration of the landscape by animals. Drawing on the work of Torsten Hägerstrand, we propose a space‐time continuum model of grizzly bears, a geomorphic agent. Through both data‐driven and conceptual applications, the model traces where and when grizzly bears are likely to wield a geomorphic impact. The model further demonstrates that… 
Sport and time geography: a good match?
This paper proposes using the rich visual “language” of Hagerstrand’s time geography to represent time-space relationships in sport, in particular within the spatial and temporal constraints of a
Spatial and Spatial-Temporal Analysis of Grizzly Bear Movement Patterns as Related to Underlying Landscapes Across Multiple Scales
Studying the movements of grizzly bears (Ursus arctos) in Alberta is imperative for scientifically informed management practices. To properly balance industry requirements with conservation
Geomorphic process-disturbance corridors: a variation on a principle of landscape ecology
The paradigm of landscape ecology describes a landscape as a mosaic of landscape elements including the matrix, patches and corridors. Corridors are described as linear disruptions to the matrix,
A time geographic approach for delineating areas of sustained wildlife use
The results showed that subadult females had significantly higher road densities within SMAs than in their potential path area home ranges, and the lowest road density was found in the SMAs of adult male grizzly bears.
A review of quantitative methods for movement data
Existing quantitative methods for analyzing movement data are reviewed to provide a synthesis of the existing literature on quantitative analysis of movement data while identifying those techniques that have merit with novel datasets.
Time geography and wildlife home range delineation

Space–Time Analysis: Concepts, Quantitative Methods, and Future Directions
Throughout most of human history, events and phenomena of interest have been characterized using space and time as their major characteristic dimensions, in either absolute or relative

Landscape Evaluation of Grizzly Bear Habitat in Western Montana
Abstract: We present a method for evaluating the cumulative effects of human activity on grizzly bear (  Ursus arctos) habitat in the Northern Continental Divide Ecosystem of western Montana. Using
Place as Historically Contingent Process: Structuration and the Time-Geography of Becoming Places
Abstract This paper presents the theoretical foundation for a different type of place-centered or regional geography. The framework rests upon an integration of time-geography and the emerging theory
Demography and Population Trend of Grizzly Bears in the Swan Mountains, Montana
The mortality, movement, and occupancy data suggest that the multiple-use zone is a population source area, and that wilderness and rural zones are sink areas, and it is recommended that wildlife managers develop a conservation strategy to promote bear population stability or growth by improving female survival while minimizing bear conflicts on private lands.
The Ecology of Winter Den Sites of Grizzly Bears in Banff National Park, Alberta
Forty-seven completed and partially dug grizzly bear (Ursus arctos) dens were examined in Banff National Park, Alberta, Canada, in 1975-76. The following environmental parameters were measured or
Grizzly Bear Habitat Selection in the Swan Mountains, Montana
It was found that avalanche chutes were used in higher proportions than available during all seasons, along with slab rock, and forested areas were among the least selected cover types during all Seasons.
Grizzly Bear Dens and Denning Activity in the Mission and Rattlesnake Mountains, Montana
Forty-one grizzly bear (Ursus arctos horribilis) dens were found in the Mission and Rattlesnake Mountains, Montana, from 1976 through 1979. Ten of these dens were used by transmitter-equipped grizzly
Immigrant Trajectories through the Rural-Industrial Transition in Wales and the United States, 1795–1850
Abstract A 29-day field investigation was conducted on a meso-tidal sand beach in Delaware Bay, New Jersey to document the contribution of local estuarine and non-local ocean waves to beach recovery
Grizzly bear digging sites for Hedysarum sulphurescens roots in southwestern Alberta
The abundance of H. sulphurescens appeared less important than the loose nature of the substrate indicating that digging time was important in optimizing energetics.
Denning of grizzly bears in the Yellowstone National Park area
Radiotelemetry was used to locate 101 grizzly bear (Ursus arctos) dens from 1975 to 1980; 35 dens were examined on the ground. Pregnant females denned in late October, and most other bears denned by
