Impact/Purpose:
In this response to the chapter by Lapointe (this volume), we discuss the question of why it is so difficult to predict salmonid–habitat relationships in gravel-bed rivers and streams.
Description:
In this response to the chapter by Lapointe (this volume), we discuss the question of why it is so difficult to predict salmonid–habitat relationships in gravel-bed rivers and streams. We acknowledge that this cannot be an exhaustive treatment of the subject and, thus, identify what we believe are several key issues that demonstrate the necessity of incorporating spatial context into the analysis of fish–habitat data. Our emphasis is on spatial context (i.e., scale and location), but it is important to note that the same principles may be applied with some modification to temporal context, which is beyond the scope of this chapter.
