Abstract: <p>Migratory fish can influence the rivers where they spawn by depositing nutrients and organic matter which increase primary and secondary production. Past research in the Laurentian Great Lakes has focused on individual tributaries, accordingly, the spatial extent of subsidies and how environmental factors influence subsidies are not clear. To determine which tributaries received… more

Name(s): Creator (cre): Brochu, Melissa, Thesis advisor (ths): Jones, Nicholas E, Thesis advisor (ths): Frost, Paul C, Degree committee member (dgc): Melles, Stephanie J, Degree granting institution (dgg): Trent University
Abstract: <p>The network composition hypothesis (NCH) suggests that i) large confluence symmetry ratios (drainage area of the tributary relative to the mainstem) and ii) landscape differences (differences in landscape characteristics between the mainstem and tributary drainages) lead to greater ecological changes below confluences. As a test of the NCH, 34 confluences were sampled in southern Ontario… more
