A buoyant plume adjacent to a headland-Observations of the Elwha River plume
Jonathan A. Warrick, Andrew W. Stevens
2011, Continental Shelf Research (31) 85-97
Small rivers commonly discharge into coastal settings with topographic complexities – such as headlands and islands – but these settings are underrepresented in river plume studies compared to more simplified, straight coasts. The Elwha River provides a unique opportunity to study the effects of coastal topography on a buoyant plume,...
Variation in local abundance and species richness of stream fishes in relation to dispersal barriers: Implications for management and conservation
K.H. Nislow, M. Hudy, B. H. Letcher, E.P. Smith
2011, Freshwater Biology (56) 2135-2144
1.Barriers to immigration, all else being equal, should in principle depress local abundance and reduce local species richness. These issues are particularly relevant to stream-dwelling species when improperly designed road crossings act as barriers to migration with potential impacts on the viability of upstream populations. However, because abundance and richness...

B. H. Letcher, J.A. Coombs, K.H. Nislow
2011, Evolutionary Applications (4) 602-615
Phenotypic variation in body size can result from within-cohort variation in birth dates, among-individual growth variation and size-selective processes. We explore the relative effects of these processes on the maintenance of wide observed body size variation in stream-dwelling brook trout (Salvelinus fontinalis). Based on the analyses of multiple recaptures of...
