The role of agent-based models in wildlife ecology and management
This paper explores the role of a habitat-modeling methodological approach, agent-based modeling, which we advocate as a promising approach for ecological research, specifically with regards to scenario planning of designated critical habitats. Expand

A Disturbance-Inventory Framework for Flexible and Reliable Landscape Monitoring
Remote sensing plays a key role in landscape monitoring, but our handling of these data in a multi-temporal time series is not yet fully developed. Of particular concern is the presence of spatialExpand

Object-based approaches to change analysis and thematic map update: challenges and limitations
small, spurious polygons created by the inconsistent delineation of persistent change features appearing in consecutive coregistered images. The issue represents a serious methodological challengeExpand

The influence of patch-delineation mismatches on multi-temporal landscape pattern analysis
We describe how sliver patches can inadvertently be created through the backdating and updating of land cover maps, and document their impact on the magnitude and trajectory of four popular landscape metrics: number of patches (NP), edge density (ED), mean patch size (MPS), and mean shape index (MSI).

Quantifying bias in pattern indices extracted from spatially offset landscape samples
Modern ecological models often account for the influence of the surrounding environment by using landscape pattern indices (LPIs) as measures of landscape structure. Ideally, the landscape samplesExpand

Processing discrete-return profiling lidar data to estimate canopy closure for large-area forest mapping and management
We performed a series of empirical experiments designed to refine the processing of discrete-return profiling light detection and ranging (lidar) data for the purpose of estimating canopy closureExpand

Energetic behavioural-strategy prioritization of Clark’s nutcrackers in whitebark pine communities: An agent-based modeling approach
We developed a spatially explicit agent-based model (ABM) to simulate the underlying behavioural mechanisms nutcrackers are most likely to employ during foraging in the South Cascades near Mt. Rainier, Washington. Expand

Technical note / Note technique Object-based approaches to change analysis and thematic map update: challenges and limitations
Bitemporal change analysis strategies performed in an object-based environment are prone to the generation of sliver objects: small, spurious polygons created by the inconsistent delineation ofExpand
