Article of the Week

This paper is about establishing habitat suitability -- it relates abiotic information (e.g. seafloor maps) to biotic information.

Zorn, T.G., P.W. Seelback, and M.H. Wiley. 2011. Developing user-friendly habitat suitability tools from regional stream fish survey data. North American Journal of Fisheries Management, 31: 41-55.

We are exploring ways to use trawl data in conjunction with abiotic datasets to look at habitat modeling and assess habitat quality. I liked the data summary grids where fish density was plotted with abiotic variables. This gave me a clearer picture of what the thresholds really meant, and a general concept of the level of error associated with thresholds. This was more transparent than a habitat suitability score of 0 or 1.
