Global Ecology and ConservationAs predators are generally larger than their prey, positive body size and trophic position relationships are typically assumed, and these relationships have helped in estimating and predicting the effects of global environmental change on the trophic ...

Seabird Trophic Position Across Three Ocean Regions Tracks Ecosystem Differences [PDF]
Frontiers in Marine Science, 2018 We analyze recently collected feather tissues from two species of seabirds, the sooty tern (Onychoprion fuscatus) and brown noddy (Anous stolidus), in three ocean regions (North Atlantic, North Pacific, and South Pacific) with different human impacts ...

Ecology and Evolution, 2022 An organism's body size plays an important role in ecological interactions such as predator–prey relationships. As predators are typically larger than their prey, this often leads to a strong positive relationship between body size and trophic position ...

Is the relationship between body size and trophic niche position time-invariant in a predatory fish? First stable isotope evidence. [PDF]
PLoS ONE, 2010 Characterizing relationships between individual body size and trophic niche position is essential for understanding how population and food-web dynamics are mediated by size-dependent trophic interactions.

Fluid‐preserved fishes are one solution for assessing historical change in fish trophic level
Ecology and Evolution, 2021 There are few resources available for assessing historical change in fish trophic dynamics, but specimens held in natural history collections could serve as this resource.

Stable Isotopes Reveal Trophic Relationships and Diet of Consumers in Temperate Kelp Forest and Coral Reef Ecosystems [PDF]
Oceanography, 2013 We explored the use of stable nitrogen (N) isotope analysis to assess trophic position of consumers in two marine ecosystems: the kelp forests of southern California and a coral atoll in the tropical Pacific.

An assessment of the trophic structure of the Bay of Biscay continental shelf food web: Comparing estimates derived from an ecosystem model and isotopic data [PDF]
, 2013 Comparing outputs of ecosystem models with estimates derived from experimental and observational approaches is important in creating valuable feedback for model construction, analyses and validation.

Trophic structure in a seabird host-parasite food web: insights from stable isotope analyses [PDF]
, 2010 Ecological studies on food webs rarely include parasites, partly due to the complexity and dimensionality of host-parasite interaction networks. Multiple co-occurring parasites can show different feeding strategies and thus lead to complex and cryptic ...

Dietary breadth and trophic position of introduced European catfish Silurus glanis in the River Tarn (Garonne River basin), southwest France [PDF]
, 2010 Although being a widely introduced and successfully established species, the European catfish Silurus glanis L. (the world’s third largest freshwater fish) remains poorly studied in its introduced areas.
