Journal ArticleDOI
Ancient climate change, antifreeze, and the evolutionary diversification of Antarctic fishes
Thomas J. Near,Alex Dornburg,Kristen L. Kuhn,Joseph T. Eastman,Jillian N. Pennington,Tomaso Patarnello,Lorenzo Zane,Daniel Alfredo Fernández,Christopher D. Jones +8 more
TL;DR: The results challenge the current understanding of the evolution of Antarctic notothenioids suggesting that the ecological opportunity that underlies this adaptive radiation is not linked to a single trait, but rather to a combination of freeze avoidance offered by AFGPs and subsequent exploitation of new habitats and open niches created by increased glacial and ice sheet activity.
Journal ArticleDOI
Latitudinal variation in the abundance and oxidative capacities of muscle mitochondria in perciform fishes
TL;DR: The results support the conclusion that increasing the volume and surface density of mitochondrial clusters is the primary mechanism for enhancing the aerobic capacity of muscle in cold-water fish.
Journal ArticleDOI
Reduction in muscle fibre number during the adaptive radiation of notothenioid fishes: a phylogenetic perspective.
Ian A. Johnston,Daniel Alfredo Fernández,Jorge Calvo,Vera L. A. Vieira,Anthony W. North,Marguerite Abercromby,Theodore Garland +6 more
TL;DR: Estimates of trait values at nodes of the maximum likelihood phylogenetic tree were consistent with a progressive reduction in fibre number during part of the notothenioid radiation, perhaps serving to reduce basal energy requirements to compensate for the additional energetic costs of antifreeze production.
Journal ArticleDOI
Dynamic somite cell rearrangements lead to distinct waves of myotome growth
Frank Stellabotte,Betsy Dobbs-McAuliffe,Daniel Alfredo Fernández,Xuesong Feng,Stephen H. Devoto +4 more
TL;DR: The surprising movement of the anterior somite cells to the external somite surface transforms a segmentally repeated arrangement of myogenic precursors into a medio-lateral arrangement similar to that seen in amniotes.
Journal ArticleDOI
Fishes of southern South America: a story driven by temperature
TL;DR: Biological and ecological data of marine and freshwater fishes from the southern Neotropics, including Patagonia, are reviewed, and several examples of dependence on temperature are reported, from glacial times to today’s climate change.
