Trophic position determines the persistence of neotropical understory birds after forest disturbance [PDF]
Ecology and EvolutionHabitat loss and degradation are key drivers of the current biodiversity crisis. Most research focuses on the question of which traits allow species to persist in degraded habitats.

Vertical Stratification Increases the Capacity of Morphological Traits to Predict Trophic Position in Neotropical Ants [PDF]
Ecology and EvolutionMorphology is a key functional trait that influences the ecophysiology of organisms. The use of morphological traits for understanding functional ecology is common in studies of ants, especially relating to their feeding biology.

Trophic Position Stability of Benthic Organisms in a Changing Food Web of an Arctic Fjord Under the Pressure of an Invasive Predatory Snow Crab, Chionoecetes opilio [PDF]
BiologyThe introduction of a large predatory snow crab, Chionoecetes opilio, into the Kara Sea is a unique situation where the impact of an invasive species affecting an otherwise undisturbed ecosystem can be observed unhindered by other ecosystem stressors ...

Diet Reconstruction Under Limited Prior Information: Dietary Contributions and Isotopic Niche of Metridium senile in the North Yellow Sea [PDF]
BiologyBiomass of the plumose anemone Metridium senile has surged in the benthic ecosystem of the North Yellow Sea in recent years. Understanding its diet and the proportional contributions of food sources is essential for assessing the ecological consequences ...

Environment International, 2021 Top predators are used as indicators of contaminant trends across space and time. However, signals are integrated over complex food webs, and variation in diet may confound such signals.

Trophic hierarchies illuminated via amino acid isotopic analysis. [PDF]
PLoS ONE, 2013 Food web ecologists have long sought to characterize the trophic niches of animals using stable isotopic analysis. However, distilling trophic position from isotopic composition has been difficult, largely because of the variability associated with ...

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.
