Burrowing rodents increase landscape heterogeneity in a desert grassland (2008, background): “…research evaluating different types of interactions, such as the effect of salmon and bears on nitrogen budgets in the riparian forests of Alaska demonstrates that the combined effect of multiple keystone species can be greater than that by either species individually (Helfield and Naiman, 2006).”
Ontogenetic niche shifts in the American Alligator establish functional connectivity between aquatic systems (2009, background): “Such horizontal transfers of biomass, energy, and nutrients have been demonstrated in studies of ‘‘mobile link” species that migrate across ecosystem boundaries, connecting otherwise separate food webs (Lungberg and Moberg, 2003; Helfield and Naiman, 2006; Kremen et al., 2007).”
Transportation of Pacific salmon carcasses from streams to riparian forests by bears (2009, background): “In recent years the complex role that Pacific salmon (genus Oncorhynchus Suckley, 1861) play in freshwater and riparian ecosystems has been investigated and reviewed (Willson and Halupka 1995; Willson et al. 1998; Gende et al. 2002; Naiman et al. 2002; Schindler et al. 2003; Helfield and Naiman 2006”
Preliminary estimates of the export of omega-3 highly unsaturated fatty acids (EPA+DHA) from aquatic to terrestrial ecosystems (2009, background): “…atherosclerosis, neural disorders, and, potentially, some cancers, as well as autoimmune diseases (e.g., Arts et al. 2001 ; Lauritzen et al. 2001 ; Broadhurst et al. 2002 ; Copeman et al. 2002 ; Silvers and Scott 2002 ; Aktas and Halperin 2004 ; Hibbeln et al. 2004, 2006 ; Simopoulos 2004a) .”
Varying effects of anadromous sockeye salmon on the trophic ecology of two species of resident salmonids in southwest Alaska (2007, background): “Largely through the action of bears (Ursus arctos Linnaeus, U. americanus Pallas), salmon carcasses are transported into riparian areas where their nutrients ultimately make their way into vegetation (Ben-David, Hanley & Schell, 1998; Hilderbrand et al., 1999; Helfield & Naiman, 2006).”
Ungulate Carcasses Perforate Ecological Filters and Create Biogeochemical Hotspots in Forest Herbaceous Layers Allowing Trees a Competitive Advantage (2009, background): “Thus far no one has investigated such a link (but see Helfield and Naiman 2006 for similar links via salmon carcasses).”
