The freshwater fauna of the South Polar Region: A 140-year review

  title={The freshwater fauna of the South Polar Region: A 140-year review},
  author={Hjg Dartnall},
The metazoan fauna of Antarctic and sub-Antarctic freshwaters is reviewed. Almost 400 species, notably rotifers, tardigrades and crustaceans have been identified. Sponges, molluscs, amphibians, reptiles and fishes are absent though salmonid fishes have been successfully introduced on some of the sub-Antarctic islands. Other alien introductions include insects (Chironomidae) and annelid worms (Oligochaeta). The fauna is predominately benthic in habitat and becomes increasingly depauperate at… Expand
Distribution of the genus Boeckella (Crustacea, Copepoda, Calanoida, Centropagidae) at high latitudes in South America and the main Antarctic biogeographic regions
An updated database of these 14 species of Boeckella generated from a combination of three sources is presented, to provide a comprehensive description of the geographic distribution of the genus south of latitude 40°S in southern South America and the three main terrestrial biogeographic regions of Antarctica.

Spatial distribution of freshwater crustaceans in Antarctic and Subantarctic lakes
It is found that variation in species composition was largely explained by the joint effect of spatial autocorrelation and climate, with little effect of biogeography – only regions within the SA province had a clearly distinct species composition. Expand
Marine habitat use and feeding ecology of introduced anadromous brown trout at the colonization front of the sub-Antarctic Kerguelen archipelago
The small migration distances observed, presence of suitable habitat, and rich local foraging opportunities suggest that trout can achieve their resource needs close to their home rivers, which may explain why the expansion of brown trout at Kerguelen has slowed. Expand
Refuges of Antarctic diversity
Abstract Antarctic terrestrial ecosystems contribute a tiny proportion of the area of the continent and host an impoverished and often cryptic biota. In recent years it has been realized that much ofExpand

A limnological reconnaissance of the Falkland Islands; with particular reference to the waterfleas (Arthropoda: Anomopoda)
The presence of fishes, molluscs, amphipods, caddis larvae, waterboatmen, parasitic cercaria, and truly planktonic rotifers make the Falkland Islands fauna markedly richer than any subantarctic, maritime Antarctic island, it is nevertheless sparse when compared with other temperate and tropical locations.

Nematodes from saline and freshwater lakes of the Vestfold Hills, East Antarctica, including the description of Hypodontolaimus antarcticus sp. n.
Some nematodes are described from freshwater and saline, marine-derived lakes of the Vestfold Hills, East Antarctica, which contained the widespread East Antarctic endemic species, Plectus frigophilus Kirjanova, 1958. Expand
The non-marine invertebrate fauna of Deception Island (Maritime Antarctic): a baseline for a comprehensive biodiversity database
A small collection of samples from terrestrial and fresh-water habitats on Deception Island yielded 14 invertebrate taxa, including four species, which are new to the island, showing evidence of posteruption colonisation by Antarctic and South American immigrant species, and historic human impact.

Additions to the freshwater fauna of Heard Island
Freshwater collections from Heard Island yielded a fauna of protozoans, one species of platyhelminth, two species of tardigrades, at least four species of nematodes, 16 species of rotifer (includingExpand
High zooplankton diversity in the extreme environments of the McMurdo Dry Valley lakes, Antarctica
It is shown that the cosmopolitan rotifer taxa identified are relatively abundant, suggesting that they have established viable populations, and suggests that the biogeographical maps have to be redrawn for several species. Expand
Freshwater Rotifera from plankton of the Kerguelen Islands (Subantarctica)
During the austral summer 1997/98, a survey was made of a series of freshwater bodies on the Kerguelen Islands, Subantarctica (49° S-69° E), in the area of Port-aux- Francais and Val Studer. TheExpand

Prior to 1962 work on freshwater within the British Sector of the Antarctic had been confined to the collection of specimens and their subsequent taxonomic evaluation. Collections were made by suchExpand
Freshwater invertebrates of subantarctic South Georgia
The fauna of South Georgia, although similar to that of the other Scotia Arc Islands, particularly Signy Island, is much richer by virtue of its lower latitude and milder climate. Expand
