Complete mitochondrial genome of Antarctic krill Euphausia superba (Eucarida: Euphausiacea) [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2017
Antarctic krill Euphausia superba is a very important species in Antarctic ecosystem. The mitochondrial genome of E. superba was completed with 16,591 bp in length, gene arrangement and order was the same as previous studies. The overall A + T content is

Towards Automated Classification of Zooplankton Using Combination of Laser Spectral Techniques and Advanced Chemometrics [PDF]

open access: yesSensors, 2022
Zooplankton identification has been the subject of many studies. They are mainly based on the analysis of photographs (computer vision). However, spectroscopic techniques can be a good alternative due to the valuable additional information that they ...

Optimal input DNA thresholds for genome skimming in marine crustacean zooplankton [PDF]

open access: yesPeerJ
Crustacean zooplanktons are key secondary and tertiary producers in marine ecosystems, yet their genomic resources remain poorly understood. To advance biodiversity research on crustacean zooplankton, this study evaluated the effectiveness of genome ...

The complete mitochondrial genome of the ice krill Euphausia crystallorophias Holt & Tattersall, 1906 (Euphausiacea, Euphausiidae), from the Ross Sea, Antarctica [PDF]

open access: yesMitochondrial DNA. Part B. Resources
The mitogenome of Euphausia crystallorophias collected from the Ross Sea Region Marine Protected Area (RSR MPA) is described for the first time. The assembled mitogenome was 17,291 bp in length and consisted of two ribosomal RNAs (rRNAs), 22 transfer ...

Trophic ecology of largehead hairtail Trichiurus japonicus in the South Sea of Korea revealed by stable isotope and stomach content analyses

open access: yesFrontiers in Marine Science, 2022
Largehead hairtail (Trichiurus japonicus) is one of the most commercially important fishes in the western North Pacific. To identify the dietary changes across ontogeny and seasons, we investigated its stomach contents and stable isotope signatures (δ13C

Food and feeding behaviour of eel-cod Muraenolepis sp., (Pisces, Gadiformes, Muraenolepididae) from the region of South Georgia [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1993
Amphipoda, Cumacea, and Macrura natantia constituted the basic food component of small eel-cod (< 20 cm). Average sized fish (20-30 cm) fed mostly on Macrura natantia and fish; big specimens (> 30 cm) consumed fish, Euphausiacea and Macrura

Food and feeding behaviour of Parachaenichthys georgianus (Fischer, 1885) and Parachaenichthys charcoti (Vaillant, 1906) (Pisces, Bathydraconidae) [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1992
Studies were made on the content of 278 stomachs of Parachaenichthys georgianus from the region of South Georgia and 30 stomachs of Parachaenichthys charcoti from the region of South Shetlands. Small P. georgianus fed mostly on Mysidacea, medium-sized on

Biometric properties and diet of common pandora, Pagellus erythrinus (Osteichthyes: Sparidae), from the eastern Adriatic sea [PDF]

open access: yesArchives of Biological Sciences, 2011
Biometric properties and diet composition were examined in 120 specimens of the common pandora caught in the eastern Adriatic Sea. Biometric analysis of the morphometric and meristic characteristics indicate a homogenous morphology stock of P ...

A new fossil mantis shrimp and the convergent evolution of a lobster-like morphotype [PDF]

open access: yesPeerJ, 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
