Landscape ecology, spatial genetics, and environmental planning

I am a landscape ecologist and data scientist.  I work on ecological questions at broad spatial extents and their applications to environmental planning and conservation.

A major theme of my research examines how the spatial structure of landscapes may influence the movement of organisms, and how spatial genetic data can inform decisions.  Applications of this work are found in wildlife conservation, environmental impact assessment, agriculture, and in preventing the spread of pests, pathogens and invasive species.

A second focus is on ecological networks: how to assess and mitigate impacts on the connectivity of ecological processes, such as those created by natural and anthropogenic disturbances. I am also part of ongoing projects in global change ecology and pollinator decline, and am involved in software development to support both citizen science and the mining of large environmental  and spatial databases.

NOTEWORTHY

The Caribou Diversity Project

A web-based citizen science project to “crowdsource” the analysis of caribou photos is up and running.  We have a working prototype here.  Help us beta-test the site and the analysis.  All that is required is your innate human ability to assess the similarity of two objects.  It’s fun!

grainscape package for R

GRAINSCAPE software is now available for grains of connectivity and minimum planar graph analyses of landscape connectivity.  A detailed tutorial has now been written, and is available here.   The software appears in the Molecular Ecology paper (Galpern et al., 2012).  GRAINSCAPE is hosted at R-forge and thanks to Andrew Fall is distributed with SELES.  Instructions to download, install, as well as manuals and tutorials are available here.

allelematch package for R

We have released ALLELEMATCH, a new genetic analysis tool, implemented in R, for identifying unique multilocus genotypes in non-invasive sampling protocols.  It is available for download from CRAN.  A paper describing it is now published in Molecular Ecology Resources.  Additional information and tutorials are available here.

R for Landscape Ecology Workshop Series

I am offering a series of three workshops in using R for a landscape ecology course at the University of Manitoba.  The workshops begin by introducing the basics of R and proceed to developing skill in the sp and raster packages.  Together these can provide an R alternative to the Spatial Analyst extension in ArcGIS.  Materials for the R for Landscape Ecology Workshop Series can be downloaded here.
