Fish assemblages were sampled in 195 randomly selected lakes in the northeastern United States during the summers of 1991-1994. Most lakes in northern Maine had three to seven minnow species, constituting 40-80% of species in each lake. Lakes in New Jersey, southern New York, and southern New England rarely had minnows, other than golden shiner (Notemigonus crysoleucas). Lakes in the Adirondacks and the remainder of northern New England had intermediate numbers. We examined minnow native ranges and autecology and evaluated species richness related to littoral predators and human disturbance. Sample data suggested alteration in the minnow assemblages over much of the region. The most consistent factor related to minnow species richness was the presence of littoral predators. Median number of minnow species was two in lakes lacking predators and zero in lakes with predators. Non-native predators, especially Micropterus spp., have been introduced throughout the Northeast; 69% of the sampled lakes had non-native predators. In the absence of predators, minnow species declined with increased human activity in the watershed and along lake shorelines. Only in northern Maine did lake minnow assemblages seem relatively intact.

The objectives of this mail survey of sawmills in the Chaudière-Appalaches region of southern Québec were (1) to establish the level of transborder interaction of these sawmills, with regard to wood sources and final markets; (2) to discover their perceptions of local versus international economic and business factors with regard to their business success; and (3) to examine the role and importance of the size of the sawmills in Chaudière-Appalaches relative to the nature of their engagement in either raw material import from or finished product export to the US. Our results demonstrate that a transborder forest economy exists and that the conception of "local" in transboundary regions must be flexible enough to permit resource management strategies, that, to some extent, ignore national boundaries. Key words: sawmill industry, transborder interaction, Chaudière-Appalaches, Québec, Northern New England
