“…However, landlocked G. maculatus has retained the ability to display several alternative life history patterns in relation to migration and the choice of reproduction sites (Chapman et al 2006;Barriga et al 2007;Boy et al 2007). The salmonid species introduced into Patagonia (Pascual and Ciancio 2007) seem to follow the same pattern, with a 'spontaneous' establishment of anadromous populations of O. mykiss and chinook salmon Oncorhynchus tshawytscha (Pascual et al 2001;Ciancio et al 2005;Soto et al 2007; D. Fernández et al, personal communication).…”

“…There were, therefore, two main factors associated to diversification in Antarctic waters: fairly constant cold temperature and empty niches. The evolution of antifreeze glycoproteins (17 million years ago according to Near 2004) is the most commonly accepted explanation for the success of the radiation of the Antarctic notothenioids, as these glycoproteins would have enabled the notothenioids to adjust to the climatic cooling that followed the opening of the Drake passage and the establishment of the Antarctic Polar Front some 20-25 million years ago (Cheng and DeVries 1991;Eastman 1993;Clarke and Johnston 1996). In agreement with this hypothesis are the findings that the most basal notothenioid families (Bovichtidae, Pseudaphritidae and Eleginopidae) are represented by non-Antarctic species (except for a single Antarctic bovichtid) with the plesiomorphic condition of lacking antifreeze glycoproteins (Eastman and Eakin 2000).…”

The latitudinal extension of southern South America imposes a thermal gradient that affects the structure of marine and freshwater fish assemblages and the biology of the species through direct exposure to the temperature gradients or by means of a web of historical and ecological relationships. We have reviewed biological and ecological data of marine and freshwater fishes from the southern Neotropics, including Patagonia, and report several examples of dependence on temperature, from glacial times to today's climate change. We were able to identify historic and present effects on the diversity of fish assemblages, isolation, southern limits for the distribution of species, and morphological variation among populations. There is a wide range of characteristics that exemplify an adaptation to low temperatures, including biochemical peculiarities, physiological adjustments, and alternative life history patterns, and these appear in both freshwater and marine, and native and exotic fishes. The consequences of stable temperature regimes in both the ocean and thermal streams deserve special mention as these shape specialists under conditions of low selective pressure. At present, habitat use and interactions among species are being subject to changes as consequences of water temperature, and some of these are already evident in the northern and southern hemispheres.

“…Because of this adaptation Antarctic fishes are found occupying most ecological niches of the Antarctic Ocean, including the surface and midwaters which are often rich in food but are ice-laden year round (for review see DeVrles 1988, Cheng & DeVries 1991, Eastman 1993. Over the past 20 years DeVries and colleagues have isolated antifreezes in 15 species of notothenioids (Eastman 1990) and in 2 non-notothenioid Antarctic species (Cheng & DeVries 1989, Schrag et al 1987.…”

Antifreeze glycopeptides and peptides have been isolated from 37 species of Antarctic fish representing the families Nototheniidae, Artedidraconidae, Bathydraconidae, Channichthyidae, Muraenolepididae. Liparididae, Zoarcidae and Myctophidae. Amino acid and carbohydrate analysis as well as antifreeze activity indicate that all investigated notothenioids contain antifreeze glycopeptides [AFGP). Pleuragramma antarcticurn, Lepidonotothen kempi, Bathydraco rnarri and Dolloidraco longedorsalis synthesize additional antifreeze molecules. The non-notothenioid species possess antifreeze peptides (AFP), except Muraenolepis marrnoratus and Macrourus holotrachys, which possess a glycosylated antifreeze pept~de similar to the AFGP found in the notothenio~d species. A novel glycopeptide comprised of the carbohydrate residue N-acetylglucosamine and the amino acids asparagine, glutamine, glycine, alanine, and traces of arginine, valine, leucine and threonine was isolated and characterized from P. antarcticum. The level of antifreeze concentration was dependent on the ambient water temperature, the depth of catch and life cycle of the species. Antifreeze activity of AFGP varies between 0.52 (Neopagetopsis ionah) and 1.20°C ( P antarctjcum) at a concentration of 20 mg ml-' Antifreeze activity of AFP is lower than 0.50°C. A linear increase in activity of the AFGP could be demonstrated concomitant with decreasing ice content. The structural diversity of antifreeze molecules and their occurrence in a wide range of Arctic and Antarctic fish species suggest that they evolved from precursor proteins before the continental drift and recently during Cenozoic glaciation into the various antifreeze molecules.

The adaptation of polar fishes to climatic changes: Structure, function and phylogeny of haemoglobin

2007

View full text Add to dashboard Cite

In the Antarctic, fishes of dominant suborder Notothenioidei have evolved in a unique thermal scenario. Phylogenetically related taxa of the suborder live in a wide range of latitudes, in Antarctic, sub‐Antarctic and temperate oceans. Consequently, they offer a remarkable opportunity to study the physiological and biochemical characters gained and, conversely, lost during their evolutionary history. The evolutionary perspective has also been pursued by comparative studies of some features of the heme protein devoted to O2 transport in fish living in the other polar region, the Arctic. The two polar regions differ by age and isolation. Fish living in each habitat have undergone regional constraints and fit into different evolutionary histories. The aim of this contribution is to survey the current knowledge of molecular structure, functional features, phylogeny and adaptations of the haemoglobins of fish thriving in the Antarctic, sub‐Antarctic and Arctic regions (with some excursions in the temperate latitudes), in search of insights into the convergent processes evolved in response to cooling. Current climate change may disturb adaptation, calling for strategies aimed at neutralising threats to biodiversity. © 2007 IUBMB IUBMB Life, 60(1): 29–40, 2008
