A High‐Resolution Microscopy System for Biological Studies of Cold‐Adapted Species Under Physiological Conditions

Small Methods, Volume 9, Issue 5, May 17, 2025.
Regions of the world permanently below 5 °C harbor significant biodiversity and understudied molecular mechanisms. This knowledge gap originates from the requirement for high‐resolution microscopy methods that maintain cold sample conditions while achieving subcellular resolution.

Record of fishes sampled in Kita-no-ura cove (Lützow-Holm Bay, East Antarctica) in January 2019

Antarctic Record, 2019
Continuous monitoring of fish fauna is important for evaluating effects of fisheries and environmental changes on the Antarctic marine ecosystem. In January 2019, we collected 52 individuals of 5 species of notothenioid species in Kita-no-ura cove ...

Pogonophryne neyelovi, a new species of Antarctic short-barbeled plunderfish (Perciformes, Notothenioidei, Artedidraconidae) from the deep Ross Sea

ZooKeys, 2013
This paper continues descriptions of new deep-water Antarctic barbeled plunderfishes of the poorly known and the most speciose notothenioid genus Pogonophryne. It is based on a comprehensive collection obtained by the authors in 2009–2010 during an

Klumpy: A tool to evaluate the integrity of long‐read genome assemblies and illusive sequence motifs

Molecular Ecology Resources, Volume 25, Issue 1, January 2025.
Abstract The improvement and decreasing costs of third‐generation sequencing technologies has widened the scope of biological questions researchers can address with de novo genome assemblies. With the increasing number of reference genomes, validating their integrity with minimal overhead is vital for establishing confident results in their ...

First Insights Into the Growth and Population Structure of Cottoperca trigloides (Perciformes, Bovichtidae) From the Southwestern Atlantic Ocean

Frontiers in Marine Science, 2020
The aim of this work was to describe the growth of Cottoperca trigloides, a notothenioid species with a non-Antarctic distribution, and to test the existence of different nursery areas and fish stocks through changes in the otolith elemental composition.

Growth Patterns and Body Condition of Notothenioid Fish (Genus Trematomus) From the Antarctic Peninsula and Weddell Sea

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
Growth patterns and body condition of 10 species of Trematomus (family Nototheniidae) collected off the Antarctic Peninsula and in the Weddell Sea during seven cruises carried out between 2002 and 2022 were estimated by length–weight relationships (LWRs) and relative condition factors (Krel).

Antifreeze protein dispersion in eelpouts and related fishes reveals migration and climate alteration within the last 20 Ma.

PLoS ONE, 2020
Antifreeze proteins inhibit ice growth and are crucial for the survival of supercooled fish living in icy seawater. Of the four antifreeze protein types found in fishes, the globular type III from eelpouts is the one restricted to a single infraorder ...

Proteolytic Enzyme Activity and mRNA Expressions of Amino Acid and Peptide Transporter Genes in Tissues of Nile tilapia (Oreochromis niloticus) Exposed to Different Salinities

Aquaculture, Fish and Fisheries, Volume 4, Issue 6, December 2024.
ABSTRACT This study examined the effects of different salinity levels and exposure time on the activity of proteolytic enzymes and the mRNA expression of amino acid (AA) and peptide transporter genes in various fish tissues of Nile tilapia (Oreochromis niloticus). O. niloticus juveniles, weighing 25.30 ± 4.82 g, were subjected to salt concentrations of

Characterization of Four Liver-Expressed Antimicrobial Peptides from Antarctic Fish and Their Antibacterial Activity

Applied Sciences, 2019
Liver-expressed antimicrobial peptides (LEAPs) are cysteine-containing cationic peptides. LEAP-1 and LEAP-2 are eight- and four-cysteine containing antimicrobial peptides found in animals, respectively.

De novo Assembly and Characterization of Patagonian Toothfish Transcriptome and Develop of EST-SSR Markers for Population Genetics

Frontiers in Marine Science, 2019
Patagonian toothfish (Dissostichus eleginoides) is a hefty notothenioid fish and a key species within the marine ecosystem with a high migratory capacity across sub-Antarctic and south American Pacific oceans. Transcriptome characterization and molecular
