Microplastic Ingestion in Three Deep-Sea Fish Species: First Ecological Insights from Stable Isotope Analysis

open access: yesMicroplastics
Microplastic (MP) pollution is an emerging environmental stressor in marine ecosystems, yet its relationship with trophic ecology remains poorly understood in deep-sea environments.

Competition and Environmental Stress Impacts on Trophic Performance of Three Sympatric Insectivorous Lizard Species in Eastern Spain

open access: yesSci
Trophic ecology is an important aspect to consider when studying interactions between species, especially in ecologically similar species. We studied the trophic ecology of three sympatric insectivorous lizards in a dune system in the Eastern Iberian ...

Trophodynamics as a Tool for Understanding Coral Reef Ecosystems

open access: yesFrontiers in Marine Science, 2018
The increased frequency of publications concerning trophic ecology of coral reefs suggests a degree of interest in the role species and functional groups play in energy flow within these systems.

Invasive signal crayfish and native noble crayfish show trophic niche shrinkage in sympatry [PDF]

open access: yesNeoBiota
Studying the coexistence of native species and invasive species with similar functional traits, habitat usage, and feeding habits is crucial for understanding the dynamics of invasion and ecological changes in the invaded ecosystem.

Between‐lake variation in the trophic ecology of an invasive crayfish [PDF]

open access: yesFreshwater Biology, 2017
Abstract The trophic ecology of invasive species has important implications for their impacts on recipient ecosystems, with omnivorous invaders potentially affecting native species and processes over multiple trophic levels. The trophic ecology of invaders might be affected by both their body size and the characteristics of their habitat due to ...

How directed is a directed network?

open access: yesRoyal Society Open Science, 2020
The trophic levels of nodes in directed networks can reveal their functional properties. Moreover, the trophic coherence of a network, defined in terms of trophic levels, is related to properties such as cycle structure, stability and percolation.

The first global deep-sea stable isotope assessment reveals the unique trophic ecology of Vampire Squid Vampyroteuthis infernalis (Cephalopoda)

open access: yesScientific Reports, 2019
Vampyroteuthis infernalis Chun, 1903, is a widely distributed deepwater cephalopod with unique morphology and phylogenetic position. We assessed its habitat and trophic ecology on a global scale via stable isotope analyses of a unique collection of beaks
