Historical Contingency Shapes Adaptive Radiation in Antarctic Fishes [PDF]
, 2020 Adaptive radiation illustrates links between ecological opportunity, natural selection, and the generation of biodiversity. Central to adaptive radiation is the association between a diversifying lineage and the evolution of phenotypic variation that ...

Draft genome assembly and transcriptome data of the icefish Chionodraco myersi reveal the key role of mitochondria for a life without hemoglobin at subzero temperatures. [PDF]
Commun Biol, 2019 Antarctic fish belonging to Notothenioidei represent an extraordinary example of radiation in the cold. In addition to the absence of hemoglobin, icefish show a number of other striking peculiarities including large-diameter blood vessels, high ...

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

Functional characterisation of the haemoglobins of the migratory notothenioid fish Dissostichus eleginoides [PDF]
, 2015 This study addresses the primary structure, the oxygen-binding properties and the CO-rebinding kinetics of the haemoglobins of the Patagonian toothfish Dissostichus eleginoides. D. eleginoides belongs to the family Nototheniidae, the most diversified

De novo gene evolution of antifreeze glycoproteins in codfishes revealed by whole genome sequence data [PDF]
, 2017 New genes can arise through duplication of a pre-existing gene or de novo from non-coding DNA, providing raw material for evolution of new functions in response to a changing environment.

INFLUENCE OF ANTIFREEZE PROTEINS ON LOCAL WATER STRUCTURE DYNAMICS IN PRESENCE OF OSMOLYTES
TASK Quarterly, 2013 Antifreeze proteins are synthesized by various organisms to enable their cells to survive subzero environment in the arctic and polar regions. These proteins produce a difference between the melting and freezing points termed as thermal hysteresis.
