The relative importance of regional, watershed, and in-stream environmental factors on fish assemblage structure and function was investigated in western Lake Superior tributaries. We selected 48 second- and third-order watersheds from two hydrogeomorphic regions to examine fish assemblage response to differences in forest fragmentation, watershed storage, and a number of other watershed, riparian, and in-stream habitat conditions. Although a variety of regional, fragmentation, and storage-related factors had significant influences on the fish assemblages, water temperature appeared to be the single most important environmental factor. We found lower water temperatures and trout–sculpin assemblages at lower fragmentation sites and higher temperatures and minnow–sucker–darter assemblages as storage increased. Factors related to riparian shading and flow separated brook trout streams from brown trout (Salmo trutta) – rainbow trout (Oncorhynchus mykiss) streams. Functionally, fish assemblages at lower fragmentation sites were dominated by cold-water fishes that had low silt tolerance and preferred moderate current speeds, while fishes with higher silt tolerances, warmer temperature preferences, and weaker sustained swimming capabilities were most common at higher storage sites. Our results suggest that site-specific environmental conditions are highly dependent on regional- and watershed-scale characters and that a combination of these factors operates in concert to influence the structure and function of stream fish assemblages.

Abstract We investigated the competitive response of oak and mountain laurel to prescribed fire on two sites in northeastern Connecticut. After nearly a decade, the competitive position of oak on moderately burned portions of both sites was little better, and in some respects worse, than on adjacent unburned controls. However, on portions of both sites where fire had killed much of the overstory, oak regrowth was vigorous and had escaped the dense mountain laurel layer. The results suggest that light understory fires alone are not sufficient for oak regeneration, and that prescribed fire should be used only as part of an integrated strategy involving harvesting of the overstory. Ecologically, the results point to the importance of severe disturbances in maintaining the structure and function of oak ecosystems. North. J. Appl. For. 13(3):119-123.
