Much of this work has been in collaboration with Jason Matthiopoulos (University of Glasgow) and Geert Aarts (Institute for Marine Resources and Ecosystem Studies, The Netherlands). Habitat selection and species distribution models are routinely used to detect correlates of space-use and species abundance. Yet, empirical models fit to data from one place or time rarely predict species occurrence or habitat use under different conditions because organisms respond non-linearly to changes in habitat availability. This phenomenon is known as a functional response in the resource selection literature. We have been working to develop more flexible methods for estimating functional responses, with the hope of improving predictions in novel landscapes (e.g., following climate change) [3,5, 6]. In addition, we have shown how many commonly applied models/methods can be interpreted under a spatial point-process framework [4, 8, 9]. I have co-authored review papers discussing methods for treating correlation and location error/missing data issues in telemetry studies [1,2], and also worked to develop new methods for validating species distribution models . These topics represent an active area of research with many opportunities for innovation and improvement.
