Trophic selectivity in aquatic isopods increases with the availability of resources [PDF]
Functional Ecology, 2020 Abstract Trophic selectivity has major influences on consumers’ fitness, stability of predator and prey populations, and nutrient fluxes in food webs. Trophic selectivity occurs when the relative abundances of resources in a consumer's diet differ from their relative abundances in the environment.

Effect of fishing intensity and selectivity on trophic structure and fishery production
Marine Ecology - Progress Series, 2017 Fishing intensity and selectivity patterns affect ecosystem structure and fisheries yield, the 2 fundamental performance measures in the ecosystem approach to fisheries. We used a simple multispecies predation model to explore the effect of alternative fishing strategies on a 3‑trophic-level food chain.

Diet and prey selectivity in co-occurring eelpout fish and bythograeid crabs in a deep-sea hydrothermal vent community [PDF]
PeerJUnderstanding the trophic ecology of deep-sea communities is central to assessing ecological structure and function, which is often lacking in remote oceanographic environments such as hydrothermal vents.

Variability in copepod trophic levels and feeding selectivity based on stable isotope analysis in Gwangyang Bay of the southern coast of the Korean Peninsula [PDF]
Biogeosciences, 2018 Trophic preference (i.e., food resources and trophic levels) of different copepod groups was assessed along a salinity gradient in the temperate estuarine Gwangyang Bay of Korea, based on seasonal investigation of taxonomic results in 2015 and stable

Community Ecology, 2011 In studies on the partitioning of resources, one issue which has been largely neglected is the change in feeding habits based on the availability of food in the environment, an aspect which is dealt with here with regard to the ichthyofauna of a tropical stream.

Temperature and Prey Availability Drive Seasonal Variations in Diet, Abundance and Condition of Forsterygion lapillum Across Two Coastal Habitats [PDF]
Ecology and EvolutionEnvironmental fluctuations in coastal waters have been increasing due to climate change and are likely to affect marine fish physiology and behaviour. Increases in temperature and turbidity can compromise food intake, body condition and abundance, among ...

Beyond polyphagy and opportunism: natural prey of hunting spiders in the canopy of apple trees [PDF]
PeerJ, 2020 Spiders (Araneae) form abundant and diverse assemblages in agroecosystems such as fruit orchards, and thus might have an important role as natural enemies of orchard pests.

Trophic strategies of the invasive Twospot livebearer (Pseudoxiphophorus bimaculatus, Teleostei: Poeciliidae) in a gradient of environmental quality in central Mexico [PDF]
Neotropical Ichthyology, 2020 Pseudoxiphophorus bimaculatus is an invasive species widely spread throughout freshwater ecosystems in central Mexico, for that reason we described its trophic strategy into a gradient of environmental quality. We sampled individuals of P. bimaculatus at

Could an event of extreme drought (2019-2020) affect the feeding ecology of Bubo magellanicus (Gmelin 1788) (Strigiformes: Strigidae) in a Mediterranean region of Chile? [PDF]
PeerJ, 2023 Global warming generates changes in environmental conditions, affecting the spatial-temporal dynamics of precipitation and temperature. Droughts, events of low rainfall, are becoming more frequent and severe.
