Diel feeding activity and intensity in the European eel Anguilla anguilla (L.) during an annual cycle in a Cantabrian stream [PDF]

open access: yesKnowledge and Management of Aquatic Ecosystems, 2008
Diel and seasonal shifts in the feeding activity and intensity of a riverine stock of European eels, Anguilla anguilla (L.), were assessed in the Río LLorín, a right-side tributary of the Río Esva drainage (northwestern Spain).

A Computational Analysis Based on Automatic Digitization of Movement Tracks Reveals the Altered Diurnal Behavior of the Western Flower Thrips, Frankliniella occidentalis, Suppressed in PKG Expression [PDF]

open access: yesInsects
The western flower thrips, Frankliniella occidentalis, a worldwide insect pest with its polyphagous feeding behavior and capacity to transmit viruses, follows a diurnal rhythmicity driven by expression of the circadian clock genes.

Diel feeding activity of Abudefduf saxatilis (Perciformes: Pomacentridae) on southwestern Atlantic reefs [PDF]

open access: yesNeotropical Ichthyology, 2023
Feeding ecology studies are crucial for understanding energy flow in reef ecosystems. In this study, we used an integrative approach to investigate the diel-feeding ecology of the sergeant-major Abudefduf saxatilis.

Studies on hake, Merluccius capensis Castelnau, 1861, from off Namibia. II. Studies on food and feeding [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1986
Feeding intensity and its relation to gonad maturity and fish size are discussed. Food elimination time and diet consumption, food composition and its fish size- and diel feeding rhythm-related changes are presented as well.

Diel Feeding Rhythm and Grazing Selectivity of Small-Sized Copepods in a Subtropical Embayment, the Northern South China Sea

open access: yesFrontiers in Marine Science, 2021
Small marine copepods are key components of the pelagic food webs in Chinese coastal waters, but very few studies have addressed their trophodynamics, with even fewer studies addressing their diel feeding rhythms.

Effects of hydrographic variability on the spatial, seasonal and diel diving patterns of southern elephant seals in the eastern Weddell Sea. [PDF]

open access: yesPLoS ONE, 2010
Weddell Sea hydrography and circulation is driven by influx of Circumpolar Deep Water (CDW) from the Antarctic Circumpolar Current (ACC) at its eastern margin. Entrainment and upwelling of this high-nutrient, oxygen-depleted water mass within the Weddell

Ecological and Behavioral Drivers of Supplemental Feeding Use by Roe Deer Capreolus capreolus in a Peri-Urban Context

open access: yesAnimals, 2020
Winter supplemental feeding of ungulates potentially alters their use of resources and ecological interactions, yet relatively little is known about the patterns of feeding sites use by target populations.

Assessing mesopelagic fish diversity and diel vertical migration with environmental DNA

open access: yesFrontiers in Marine Science, 2023
Mesopelagic fishes are an important component of the world’s oceans in terms of their abundance, biomass, and ecosystem function. These fishes are important contributors to the biological carbon pump via their feeding and behaviors, whereby they ...
