Evaluating Species Distribution Models -
Working with colleagues at the University of Alberta, I am building on
previous research designed to assess the sensitivity and uncertainty
of species distribution models to error and bias in source
data and choices in model design and structure. We are currently
looking at one type of species distribution model, a resource
selection function (RSF), and developing an improved method for
evaluating the validity of model predictions. We also are assessing the influence of data contamination on model predictions
for used vs. availability sampling strategies. |

Effects of Disturbance on the Abundance of Mtn.
Caribou - Dr. Dale Seip, of the BC Ministry of Forests, and I,
are using resource selection functions and population survey
data to estimate the number of endangered mountain caribou displaced
from a late winter range frequented by recreational snowmobilers.
This study will provide further insight into the relationship between
species occurrence and abundance and provide direction to recovery
planning efforts for mountain caribou. |
