• Remote sensing for biodiversity science and conservation (2003, background): “Terrain information is essential for models of surface processes (such as sediment yield), statistical analyses of the spread of invasive species, and detecting habitat conditions [21, 30 ].”
• Crying wolf, crying foul, or crying shame: alien salmonids and a biodiversity crisis in the southern cool-temperate galaxioid fishes? (2006, background): “Salmonids as ersatz native species in southern lands Scott and Helfman (2001) recognised how widely some salmonids have become across (mostly) cool-temperate latitudes of the globe, including much translocation within continental areas where they are indigenous (MacCrimmon and Marshall 1968;…”
• Changes in Fish Assemblage Structure Upstream of Impoundments within the Upper Wabash River Basin, Indiana (2006, background): “After disturbances and habitat degradation, an invasion by native generalist species can lead to an intermediate phase where no change or even an increase in species richness occurs ( Scott and Helfman 2001 ).”
• Forecasting faunal and floral homogenization associated with human population geography in North America (2006, background): “Scott and Helfman (2001) used a watershed-scale measure of land use intensity (describing % of basin deforested, and density of buildings and roads), and suggested that land-use change associated with urbanization has essentially led to abiotic homogenization of streambed substrate conditions (in…”
• Homogenization of Freshwater Faunas (2002, background): “Scott & Helfman (2001) cautioned that assessments of the integrity or conservation value of aquatic habitats should consider the effects of native invasions, as well as invasions by exotic species.”
• Effects of increased suspended sediment on growth rate and gill condition of two southern Appalachian minnows (2007, background): “Previous research primarily relates excessive sedimentation to habitat loss and fragmentation with concomitant fish assemblage homogenization and loss of sensitive and endemic fish species (Berkman and Rabeni 1987; Burkhead et al. 1997; Scott and Helfman 2001; Sutherland et al. 2002; Walters et al”
• Taxonomic and functional homogenization of an endemic desert fish fauna (2012, background): “Limited empirical evidence suggests that the initial consequence of non-native species introduction is to increase the distinctiveness of biotas (Scott & Helfman, 2001); however, a detailed investigation of the spatiotemporal patterns of biotic homogenization or differentiation is lacking.”
• Ecological correlates of fish movement in a network of Virginia streams (2004, background): “Ultimately, they may be replaced by generalist invaders that find the homogeneous habitat suitable (Scott and Helfman 2001).”
• Aquaculture Production and Biodiversity Conservation (2009, background): “However, greater species richness does not always mean improved biodiversity, as globally or locally invasive species could be responsible for the increased richness (Scott and Helfman 2001).”
• An analysis of homogenization and differentiation of Canadian freshwater fish faunas with an emphasis on British Columbia (2004, background): “…January 29, 2004 8:23:47 AM B.C., and this results in some level of homogenization (or differentiation) on very small scales that can have the same consequences as at the level of aquatic ecoregions within the province as a whole (e.g., see Scott and Helfman 2001).”
• Conservation status of imperiled north American freshwater and diadromous fishes (2008, positive): “The AFS-ESC list augments regional fish conservation analyses, such as recent works on faunal homogenization (Rahel 2000; Scott and Helfman 2001; Taylor 2004), where information on taxonomy and geographic distribution is vital. Listing criteria used by AFS-ESC should be expanded in the future to mor”

• Biotic homogenization: a new research agenda for conservation biogeography (2006, background): “Scott & Helfman (2001) used a watershed-scale measure of land-use intensity describing the degree of deforestation and density of buildings and roads, and suggested that land-use change associated with urbanization has essentially led to abiotic homogenization of streambed substrate conditions.”
