Targeting alternate prey to understand caribou and moose habitat management choices in a regenerating landscape: Increasing functional habitat for caribou in west-central ranges Woodland caribou calving areas and calf survival in relation to habitat selection, anthropogenic disturbance, and exposure to . Species distribution models (SDMs) are widely used in the fields of macroecology, biogeography and biodiversity research for modelling species geographic distributions based on Cited by:
The conceptual background for habitat distribution modelling is rooted in the niche concept (Hutchinson ). The distinction of both indirect (distal) as well as direct or resource variables (proximal) was important for theoretical advances in this field, and for testing assumptions based on the species’ niche (Austin ).

Species Distribution Modelling SDM is one of the fastest growing domains of ecological modelling, based on a wide variety of software that aim to interpolate the sparse data we have on where species occur, or extract functional relationships between species’ occurrence and physical factors such as . This contribution identifies spatial characteristics of tree diameter in a temperate forest in north-eastern China, based on a fully censused observational study area covering × m. Mark correlation analysis with three null hypothesis models was used to determine departure from expectations at different neighborhood distances. Tree positions are clumped at all investigated scales in all.

Monserud et al. () created a spatial model of site index for lodgepole pine (Pinus contorta) in Alberta using Hutchinson's thin-plate smoothing splines with inputs of latitude, longitude.
Finally, we do not intend that this paper be seen as an exhaustive review of the state-of-the-art in modelling succession-disturbance dynamics. 2 Recent reviews of spatial models of vegetation dynamics have considered, in some depth, the conceptual and methodological underpinnings of frameworks including species distribution models (e.g.

Forest Ecology and Management. The spatial distribution of instream wood influences important ecological processes but has proven challenging to describe quantitatively.
We present a modified version of a previously described metric used to quantify the spatial extent and pattern of instream wood distribution, then apply this approach in evaluating the distribution of wood habitat in forested northeastern North American Cited by: 7.
Empirical models for spatial distribution of wildlife, given data from a complete census or a random sample of sites, are reviewed briefly. The use of covariates, recorded at different resolutions, for modelling spatial distribution is explored. Presentation of.
The study was conducted in Council, Alaska (64º50′ ″ N, º42′″ W), in an area where representative arctic tundra vegetation was found ().Alaska tundra was classified into 8 broad vegetation types (Johnson and Vogel ).More specifically, our study site can be defined by Eriophorum–Carex wet meadow, and spruce forest distributed within a few-kilometer-distance by: 6.
Arbitrary scale models always required the addition of spatial eigenvectors. 75% (50–%) of the known predictors were selected at scales similar to the known scale (within 3 km). In the curlew model, predictors at large, medium and small spatial scales were selected, suggesting that for appropriate landscape-scale models multiple scales.
The spatial distribution and intraspecific spatial relations among the size classes of each tree species were analyzed by single-variable and double-variable O-ring functions (Figure 3, 4).B Cited by: The main goal of this exploratory project was to quantify seedling density in post fire regeneration sites, with the following objectives: to evaluate the application of second order image texture (SOIT) in image segmentation, and to apply the object-based image analysis (OBIA) approach to develop a hierarchical classification.
With the utilization of image texture we successfully developed a Cited by: 4. Identifying the spatial pattern of wood distribution in northeastern North American streams Clifford E.

Lacunarity measures the ‘gappiness’ of the landscape element of. In contrast, with a uniform seed rain, the distribution of soil nitrogen availability was more uniform and “hotspots” were more localized. Thus, the spatial pattern of an ecosystem process (nitrogen cycling) is determined by seed dispersal and competition for light among competing by: We evaluated spatial patterns of soil N and C mineralization, microbial community composition (phospholipid fatty acids), and local site characteristics (plant/forest floor cover, soil pH, soil %C and %N) in a ha burned black spruce forest stand in interior Alaska.
Results indicated that factors governing soil N and C mineralization varied at two different by: Typically, spatial point patterns are viewed as bounded realiza-tions of a spatial point process in R2within a spatial window W, which might be of any arbitrary shape.
Theoretically, the point pattern can be observed beyond W. A spatial point pattern is called a sampled point pattern when all theFile Size: 3MB. Methodology and Principal Findings. Aerial photographs providing GPS positions for large, canopy trees, the complete census of a ha and ha area, diameter at breast height data from haphazardly sampled trees and long-term phenology data from six trees were used to fit 1) a point process model of tree spatial distribution and 2) a generalized linear mixed-effect model of temporal variation Cited by:.
Mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) is an aggressive bark beetle that attacks numerous Pinus spp. and causes extensive mortality in lodgepole pine (Pinus contorta Douglas ex Loudon; LPP) forests in the western United States and Canada.

In west-central Alberta, pine forests comprise much of caribou and grizzly bear habitat. This project will determine the response of these threatened species to MPB-related disturbance of these areas.
