Insights into the diet and trophic ecology of white sharks (Carcharodon carcharias) gained through DNA metabarcoding analyses of cloacal swabs

Environmental DNA, Volume 5, Issue 6, Page 1362-1377, November 2023., 2023
This study explores the diet of one of the world's most recognizable predators, the white shark. Dietary assessments are performed by genomic analysis of cloacal swabs collected from approximately 200 live sharks. Findings from this study provide insights into the trophic ecology and feeding behavior of the white shark and key marine resources ...

Changes in the diet of predatory ribbonfish Trichiurus lepturus Linnaeus,   1758 with increasing body size along Chennai coast [PDF]

, 2017
In recent years, it has been recognised that predatory fishes are rapidly declining in marine habitats. Hence, gathering information on biological characteristics such as dietary dynamics of predatory fishes has assumed importance.

Contrasting metacommunity patterns of fish and aquatic insects in drainage ditches of paddy fields

Ecological Research, Volume 37, Issue 5, Page 635-646, September 2022., 2022
Fish metacommunities were mainly influenced by local environmental factors in summer, and by watercourse‐based spatial factors in spring and autumn, as hydrological connectivity among habitats improves in the summer. In contrast, only overland‐based spatial factors significantly affected metacommunity structures of aquatic insects with flying adults in

Substantial intraspecific trait variation across a hydrological gradient in northern Australian fishes

Ecosphere, Volume 13, Issue 7, July 2022., 2022
Abstract Trait‐based models of ecological communities and ecosystem functioning often fail to account for intraspecific variation in functional traits, assuming that intraspecific variability is negligible compared with interspecific variability. However, this assumption remains poorly tested across vertebrate animals where past studies routinely ...

Swimming abilities of temperate pelagic fish larvae prove that they may control their dispersion in coastal areas [PDF]

, 2019
The Sense Acuity and Behavioral (SAAB) Hypothesis proposes that the swimming capabilities and sensorial acuity of temperate fish larvae allows them to find and swim towards coastal nursery areas, which are crucial for their recruitment. To gather further

Independent evolution of the specialized pharyngeal jaw apparatus in cichlid and labrid fishes [PDF]

, 2007
Background Fishes in the families Cichlidae and Labridae provide good probable examples of vertebrate adaptive radiations. Their spectacular trophic radiations have been widely assumed to be due to structural key innovation in pharyngeal jaw apparatus ...

Optimal Strouhal number for swimming animals [PDF]

, 2011
To evaluate the swimming performances of aquatic animals, an important dimensionless quantity is the Strouhal number, St = fA/U, with f the tail-beat frequency, A the peak-to-peak tail amplitude, and U the swimming velocity.

Reproductive biology of two grey mullet species (Actinopterygii: Mugiliformes: Mugilidae) in a northern Aegean Sea estuarine system [PDF]

Acta Ichthyologica et Piscatoria, 2011
Background. Limited information is available on the reproductive biology of grey mullets mainly because it is very difficult to collect fully mature specimens.
