Invasion of stream fishes into low trophic positions [PDF]
Ecology of Freshwater Fish, 2007 Abstract – In the absence of other life‐history constraints, fishes that can feed at low trophic levels (i.e., omnivores/detritivores) are predicted to be successful invaders because their food resources during the colonization and integration phases of the invasion are rarely limiting.

Not all jellyfish are equal: isotopic evidence for inter- and intraspecific variation in jellyfish trophic ecology [PDF]
PeerJ, 2015 Jellyfish are highly topical within studies of pelagic food-webs and there is a growing realisation that their role is more complex than once thought.

Resource use, niche width, and trophic position reveal diverse trophic structure in a tidal freshwater zone fish community. [PDF]
J Fish BiolAbstractThe tidal freshwater zone is an aquatic transition zone that links a river to its estuary and provides an important habitat used in the life cycle of resident and migratory fishes. Yet, information on the trophic structure of fishes in this habitat is scarce.

Frontiers in Ecology and Evolution, 2020 A wide trophic niche and high trophic plasticity are often invoked to explain the successful establishment of many aquatic invaders, but there is little information regarding the diet of most invasive fish in European waters.

Scientific Reports, 2021 Trophic ecology of detrital-based food webs is still poorly understood. Abyssal plains depend entirely on detritus and are among the most understudied ecosystems, with deposit feeders dominating megafaunal communities.

Frontiers in Marine Science, 2022 Largehead hairtail (Trichiurus japonicus) is one of the most commercially important fishes in the western North Pacific. To identify the dietary changes across ontogeny and seasons, we investigated its stomach contents and stable isotope signatures (δ13C

Bioaccumulation and trophic dilution of human pharmaceuticals across trophic positions of an effluent-dependent wadeable stream [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2014 Though pharmaceuticals are increasingly observed in a variety of organisms from coastal and inland aquatic systems, trophic transfer of pharmaceuticals in aquatic food webs have not been reported. In this study, bioaccumulation of select pharmaceuticals was investigated in a lower order effluent-dependent stream in central Texas, USA, using isotope ...

Impacts of intensive logging on the trophic organisation of ant communities in a biodiversity hotspot. [PDF]
PLoS ONE, 2013 Trophic organisation defines the flow of energy through ecosystems and is a key component of community structure. Widespread and intensifying anthropogenic disturbance threatens to disrupt trophic organisation by altering species composition and relative

Trophic position influences the efficacy of seabirds as metal biovectors [PDF]
Proceedings of the National Academy of Sciences, 2010 Seabirds represent a well documented biological transport pathway of nutrients from the ocean to the land by nesting in colonies and providing organic subsidies (feces, carcasses, dropped food) to these sites. We investigated whether seabirds that feed at different trophic levels vary in their potency as biovectors of metals, which can ...
