Feeding ecology of Serrasalmus gouldingi (Characiformes: Serrasalmidae) in the lower Anapu River region, Eastern Amazon, Brazil [PDF]

open access: yesActa Amazonica, 2016
Studies on feeding ecology of fishes are important to understand the relationship between species and environmental seasonal variations. In tropical rivers, these relationships are mainly modeled by hydrological patterns.

Goal-Directed Travel in the Nocturnal Javan Slow Loris (Nycticebus javanicus)

open access: yesEcologies, 2023
An animal’s ability to navigate its home range in search of essential resources is a key aspect of its ecology. To reach these resources, animals employ varying navigational processes depending on their exocentric or egocentric view of their environment.

Multilevel feeding ecology – an introduction [PDF]

open access: yesEntomologia Experimentalis et Applicata, 2018
All organisms need to acquire nourishment in sufficient quantity and quality to grow and reproduce. Food sources need to be located and choices need to be made with respect to their favourability. This issue addresses host location (plants by phytophagous insects, prey by predators or parasitoids) and performance (of phytophagous and carnivorous ...

Feeding Ecology of Nemipterus japonicus in Beibu Gulf

open access: yesProgress in Fishery Sciences, 2023
The Beibu Gulf is the fourth largest Chinese fishing ground, with rich fishery resources and a significant role in marine fishery production. The feeding ecology of fish is important to explain the structure and function of marine ecosystems.

Kinematics and energetics of foraging behavior in Rice’s whales of the Gulf of Mexico

open access: yesScientific Reports, 2023
Rorqual foraging behavior varies with species, prey type and foraging conditions, and can be a determining factor for their fitness. Little is known about the foraging ecology of Rice’s whales (Balaenoptera ricei), an endangered species with a population

Feeding ecology in sea spiders (Arthropoda: Pycnogonida): what do we know?

open access: yesFrontiers in Zoology, 2018
Sea spiders (Pycnogonida) are a widespread and phylogenetically important group of marine arthropods. However, their biology remains understudied, and detailed information about their feeding ecology is difficult to find.

Ecological insights on the feeding behaviour of waterbirds in an Important Bird and Biodiversity Area of South West Johor Coast, Malaysia [PDF]

open access: yesBiodiversity Data Journal
Mangroves and mudflats are essential intertidal habitats that support benthic communities, providing critical feeding grounds for waterbirds. However, the degradation of these habitats due to coastal reclamation poses significant threats to prey ...

Stable isotope and signature fatty acid analyses suggest reef manta rays feed on demersal zooplankton. [PDF]

open access: yesPLoS ONE, 2013
Assessing the trophic role and interaction of an animal is key to understanding its general ecology and dynamics. Conventional techniques used to elucidate diet, such as stomach content analysis, are not suitable for large threatened marine species.

Hypotheses and lessons from a native moth outbreak in a low‐diversity, tropical rainforest

open access: yesEcosphere, 2022
Outbreaks of defoliating insects in low‐diversity tropical forests occur infrequently but provide valuable insights about outbreak ecology in temperate environments and in general.
