A new fossil mantis shrimp and the convergent evolution of a lobster-like morphotype [PDF]
PeerJ, 2021 Eumalacostracan crustaceans all have a more or less stereotypic body organisation in the sense of tagmosis. Originally, this included a head with six segments (ocular segment plus five appendage-bearing segments), a thorax region with eight segments, and

Diet of three juvenile fish species of the coastal zone of a Southwest Atlantic beach, Brazil
Acta Scientiarum: Biological Sciences, 2022 Surf zones are associated with a shelter area, nursery and feeding for several species of fish. In this study, the dietary habits of three species of fish with demersal habits (Gulf kingcroaker Menticirrhu gracilis, Whitesea catfish Genidens barbus and ...

Limnology and Oceanography, Volume 68, Issue 12, Page 2688-2702, December 2023., 2023 Abstract The effects of environmental change on zooplankton communities, and more broadly, pelagic ecosystems are difficult to predict due to the high diversity of ecological strategies and complex interspecific interactions within the zooplankton. Trait‐based approaches can define zooplankton functional groups with distinct responses to environmental ...

Marine Ecology, Volume 44, Issue 3, June 2023., 2023 Abstract Molecular tools increasingly refine and improve the identification of zooplankton organisms based on phenotypic features, providing a more robust and comprehensive species description. Integration of data helps revealing the hidden diversity of zooplankton and facilitating the detection of rare and non‐indigenous species.

Journal of Fish Biology, Volume 102, Issue 5, Page 1129-1140, May 2023., 2023 Abstract Brown trout (Salmo trutta L. 1758) and Arctic charr [Salvelinus alpinus (L. 1758)] tagged with acoustic transmitters migrated from fresh water to the sea mainly in May and June, but with large individual variation in migration timing. For S. trutta, large individuals (42–86 cm total length) migrated earlier in the season than small individuals

Lighten up the dark: metazoan parasites as indicators for the ecology of Antarctic crocodile icefish (Channichthyidae) from the north-west Antarctic Peninsula [PDF]
PeerJ, 2018 Due to its remote and isolated location, Antarctica is home to a unique diversity of species. The harsh conditions have shaped a primarily highly adapted endemic fauna. This includes the notothenioid family Channichthyidae.

Nanopore short‐read sequencing: A quick, cost‐effective and accurate method for DNA metabarcoding
Environmental DNA, Volume 5, Issue 2, Page 282-296, March 2023., 2023 Advances in sequencing technologies are revolutionising studies of animal diets and resolving complex predator‐prey relationships. In this study, we compared the short‐read sequencing capability of the portable Nanopore MinION to that of the Illumina MiSeq for determining the diet of juvenile lanternfish living in the mesopelagic zone of the Indian ...

A note on stomach contents of minke whales (Balaenoptera acutorostrata) in Icelandic waters
NAMMCO Scientific Publications, 2000 There is limited available information on food habits of minke whales (Balaenoptera acutorostrata) in coastal Iceland. Sixty-eight minke whales were examined for stomach contents; 51.5% contained fish only, 22.1 % krill (Euphausiacea) only, 25.0% fish ...

Taxonomic review of the orders Mysida and Stygiomysida (crustacea, peracarida). [PDF]
PLoS ONE, 2015 The order Mysida (2 families, 178 genera, 1132 species) contains species across a broad range of habitats, such as subterranean, fresh, brackish, coastal, and surface to deep-sea habitats. The Stygiomysida (2 families, 2 genera, 16 species), however, are
