Aquatic productivity and food webs of desert river ecosystems (2006, background): “However, there is a growing view that these models of ecosystem function have understated the role of autochthonous (i.e. produced within the system) sources in large rivers (Lewis et al., 2001; Thorp & Delong, 2002; Bunn et al., 2003; Winemiller, in press).”
Trophic coupling across the St. Lawrence River estuarine transition zone (2003, background): “Work on large rivers elsewhere has similarly drawn attention to the likely importance of phytoplankton for food web energy and biomass, even within such ‘heterotrophic’ ecosystems (Thorp & Delong 2002).”
How important are terrestrial organic carbon inputs for secondary production in freshwater ecosystems (2017, background): “Although the significance of low P/R ratios and/or net heterotrophy for upper trophic levels has been disputed (Rosenfeld & Mackay, 1987; Thorp & Delong, 2002), many of the papers in the zooplankton allochthony literature begin by emphasising the supposed importance of net heterotrophy for upper…”
River and wetland food webs in Australia's wet–dry tropics: general principles and implications for management (2005, background): “However, there is a growing view that earlier models of ecosystem function have understated the role of autochthonous (i.e. produced within the system) production in large rivers (Winemiller 2004; Thorp et al. 1998 ; Bunn et al. 2003; Thorp and Delong 2002).”
Habitat and resource use by larval and juvenile fishes in an arid‐land river (Rio Grande, New Mexico) (2006, background): “Data from stable isotope studies of mesic-land tropical and temperate floodplain rivers indicate that phytoplankton, not epibenthic algae, is the predominate source of organic carbon for food webs (Lewis et al., 2000; Thorp & Delong, 2002; Herwig et al., 2004), despite numerical dominance of alloc”
The role of sewage in a large river food web (2003, background): “The metabolism of larger rivers is dominated by fine particulates transported in the main channel, although autochthonous production in the littoral zone and allochthonous inputs from riparian vegetation and floodplains are energetically more important to higher trophic levels ( Thorp and Delong 199”
Variability of fish diets between dry and flood periods in an arid zone floodplain river (2005, background): “The role of autochthonous inputs into the food webs of large rivers in particular, has more recently been suggested to play a larger role in ecosystem function than was previously thought (Thorpe & Delong, 2002; Bunn et al., 2003).”
Attached Algae: The Cryptic Base of Inverted Trophic Pyramids in Freshwaters (2017, background): “This is so irrespective of whether the ecosystem as a whole is a source or a sink for carbon (Thorp & Delong 2002, Brett et al. 2017).”
Global and Regional Patterns in Riverine Fish Species Richness: A Review (2011, background): “Even if considering that terrestrial productivity gives a correct estimation of aquatic productivity (as food webs supporting fish are largely based on allochthonous inputs), using estimates of terrestrial primary productivity probably under-estimates true aquatic productivity (see [58] for a review”
