Proteomic analysis of the ATP synthase interactome in notothenioids highlights a pathway that inhibits ceruloplasmin production [PDF]

American Journal of Physiology - Regulatory Integrative and Comparative Physiology, 2022
Antarctic notothenioids have unique adaptations that allow them to thrive in subzero Antarctic waters. Within the suborder Notothenioidei, species of the family Channichthyidae (icefish) lack hemoglobin and in some instances myoglobin too.

Fish muscle: the exceptional case of notothenioids [PDF]

Fish Physiology and Biochemistry, 2008
Fish skeletal muscle is an excellent model for studying muscle structure and function, since it has a very well-structured arrangement with different fiber types segregated in the axial and pectoral fin muscles. The morphological and physiological characteristics of the different muscle fiber types have been studied in several teleost species.

On the origin and trigger of the notothenioid adaptive radiation. [PDF]

PLoS ONE, 2011
Adaptive radiation is usually triggered by ecological opportunity, arising through (i) the colonization of a new habitat by its progenitor; (ii) the extinction of competitors; or (iii) the emergence of an evolutionary key innovation in the ancestral ...

Adaptive Radiation in Antarctic Notothenioids [PDF]

, 2018
Antarctic notothenioids have undergone adaptive radiation in order to survive. Some challenges notothenioids face includes maintaining proper organ function, increased blood viscosity, maintaining appropriate protein levels, and conserving energy. Many of the solutions that the Notothenioidei have evolved to these challenges are considered to be â ...

Molecular pedomorphism underlies craniofacial skeletal evolution in Antarctic notothenioid fishes [PDF]

BMC Evolutionary Biology, 2010
Background Pedomorphism is the retention of ancestrally juvenile traits by adults in a descendant taxon. Despite its importance for evolutionary change, there are few examples of a molecular basis for this phenomenon.

Evolution of the immune system in Antarctic notothenioids [PDF]

, 2022
Notothenioids are the most abundant group of teleost fish found in the Southern Ocean. These fish evolved relatively recently from a single benthic ancestor and radiated and expanded in the extreme cold of Antarctica waters and their physiology was adapted accordingly. Surprisingly, little is known about their immune system and how immune defences were

Sex Differentiation and Long-Distance Gene Flow in the Elusive Antarctic Fish <i>Aethotaxis mitopteryx</i>. [PDF]

Ecol Evol
This genetic study of a rare Antarctic fish, the longfin icedevil (Aethotaxis mitopteryx) investigates population connectivity across the Weddel Sea, revealing little to no differentiation even over vast geographic distances. Unexpectedly, the strongest genetic differentiation is instead observed between male and female fishes, which suggests a ...

Xenobiotic metabolism and its physiological consequences in high-Antarctic Notothenioid fishes. [PDF]

Polar Biol, 2022
The Antarctic ecosystem is progressively exposed to anthropogenic contaminants, such as polycyclic aromatic hydrocarbons (PAHs). So far, it is largely unknown if PAHs leave a mark in the physiology of high-Antarctic fish. We approached this issue via two

Chromosomal-Level Assembly of Antarctic Scaly Rockcod, Trematomus loennbergii Genome Using Long-Read Sequencing and Chromosome Conformation Capture (Hi-C) Technologies

Diversity, 2021
Trematomus species (suborder Notothenioidei; family Nototheniidae) are widely distributed in the southern oceans near Antarctica. There are 11 recognized species in the genus Trematomus, and notothenioids are known to have high chromosomal diversity (2n =

Productivity and Change in Fish and Squid in the Southern Ocean

Frontiers in Ecology and Evolution, 2021
Southern Ocean ecosystems are globally important and vulnerable to global drivers of change, yet they remain challenging to study. Fish and squid make up a significant portion of the biomass within the Southern Ocean, filling key roles in food webs from ...
