Species distribution and temperature range of select Pacific groundfish species occurring in Queen Charlotte Sound and Hecate Strait, British Columbia / by Andrew McMillan, Jean-Baptiste Lecomte and Karen... : Fs97-6/3426E-PDF
"Species distribution models are developed through a framework of ecological knowledge, data collection methods, and statistical analyses to estimate the distribution or potential habitat of a given species. Developing each component involves consideration of the limitations of each framework component, such as sampling logistics or poorly understood physiology. Here, we apply a Bayesian hierarchical model that accounts for the structure of trawl catch biomass data to estimate the spatial distribution of 18 species sampled by DFO synoptic trawl surveys off the northern coast of British Columbia. This model uses a compound Poisson-Gamma distribution to represent the spatial structure of the trawl biomass and a log-linear link function to account for influences of depth, temperature, and survey year. Model performance was species dependent and favoured species with greater spatial representation in the data"--Abstract, page iv.
