Where buffalo and cattle meet: Modelling interspecific contact risk using cumulative resistant kernels

Publications Posted on: April 03, 2018
African buffalo the primary source of foot and mouth disease (FMD) infection for livestock in South Africa. Predicting the spatial drivers and patterns of buffalo–cattle contact risk is crucial for developing effective FMD mitigation strategies. Therefore, the goal of this study was to predict fine-scale, seasonal contact risk between cattle and buffaloes straying into communal lands adjacent to Kruger National Park.

Why did the bear cross the road? Comparing the performance of multiple resistance surfaces and connectivity modeling methods

Publications Posted on: September 20, 2016
There have been few assessments of the performance of alternative resistance surfaces, and little is known about how connectivity modeling approaches differ in their ability to predict organism movements. In this paper, we evaluate the performance of four connectivity modeling approaches applied to two resistance surfaces in predicting the locations of highway crossings by American black bears in the northern Rocky Mountains, USA.

A multi-scale assessment of population connectivity in African lions (Panthera leo) in response to landscape change

Publications Posted on: October 22, 2015
Habitat loss and fragmentation are among the major drivers of population declines and extinction, particularly in large carnivores. Connectivity models provide practical tools for assessing fragmentation effects and developing mitigation or conservation responses.

Evaluating population connectivity for species of conservation concern in the American Great Plains

Publications Posted on: October 23, 2013
Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing an improved ability to predict the effects of landscape change on population connectivity at vast spatial extents.

Multi-taxa population connectivity in the northern Rocky Mountains

Publications Posted on: May 24, 2012
Effective broad-spectrum biodiversity conservation requires that conservation strategies simultaneously meet the needs of multiple species. However, little is known about how maintaining habitat connectivity for one species or species group may also act as an umbrella for other species.

Ecological associations, dispersal ability, and landscape connectivity in the northern Rocky Mountains

Publications Posted on: April 03, 2012
Population connectivity is a function of the dispersal ability of the species, influences of different landscape elements on its movement behavior, density and distribution of the population, and structure of the landscape. Often, researchers have not carefully considered each of these factors when evaluating connectivity and making conservation recommendations.
