“…Our understanding of Antarctic freshwater biodiversity is based on studies that began at the beginning of the 20th century [439] and now encompass most of the major ice-free regions [440]. In each of these regions, a mixture of lakes, ponds and flowing waters are found.…”

In this overview (introductory article to a special issue including 14 papers), we consider all main types of natural and artificial inland freshwater habitas (fwh). For each type, we identify the main biodiversity patterns and ecological features, human impacts on the system and environmental issues, and discuss ways to use this information to improve stewardship. Examples of selected key biodiversity/ecological features (habitat type): narrow endemics, sensitive (groundwater and GDEs); crenobionts, LIHRes (springs); unidirectional flow, nutrient spiraling (streams); naturally turbid, floodplains, large-bodied species (large rivers); depth-variation in benthic communities (lakes); endemism and diversity (ancient lakes); threatened, sensitive species (oxbow lakes, SWE); diverse, reduced littoral (reservoirs); cold-adapted species (Boreal and Arctic fwh); endemism, depauperate (Antarctic fwh); flood pulse, intermittent wetlands, biggest river basins (tropical fwh); variable hydrologic regime—periods of drying, flash floods (arid-climate fwh). Selected impacts: eutrophication and other pollution, hydrologic modifications, overexploitation, habitat destruction, invasive species, salinization. Climate change is a threat multiplier, and it is important to quantify resistance, resilience, and recovery to assess the strategic role of the different types of freshwater ecosystems and their value for biodiversity conservation. Effective conservation solutions are dependent on an understanding of connectivity between different freshwater ecosystems (including related terrestrial, coastal and marine systems).

“…David and Priestley (1914a) observed that volcanic bombs found 4-5 miles from the active crater must have been carried in a west-north-west and north-west direction during a strong south-easterly blizzard. The same south-easterly winds may force the steam cloud toward the north-west edge of the crater where the aqueous vapour condensing on the cold soil surface may produce temporary moist conditions.…”

“…Three distinct features along the western slopes of the peak represent the remains of three old craters; they are found at about 300 m, at 3,400 m, and at 3,830 m. The geology of Mt Erebus has been described by David and Priestley (1914a) in connection with the first climbing of the peak. They reported trachyte in the lower part of the mountain, partially embedded in kenyte resulting from a subsequent eruption.…”

Soils of Mount Erebus, Antarctica

Soil distribution on Mt Erebus is restricted by the extensive ice and snow cover and by the rugged topography. Soil occurrence is limited to rock exposures, to areas kept free of ice by the hot vapours and heat of fumaroles, and to areas near the active crater. The soils of Mt Erebus are lithosols, and because of their acid reaction are unique among the soils of South Victoria Land, the Commonwealth Range, and the Bunger Oasis. Also, the mineral assemblage of these lithosols includes minerals not yet reported among the little-studied Antarctic soils. These outstanding characteristics are related to the hydrothermal processes associated with the volcanic activity of the region.A sample obtained near an active fumarole showed considerable microbiological activity and minerals such as allophane, gibbsite, illite, and feldspar. Allophane, an alteration product of volcanic ash, is forming at present in New Zealand and Japan. A sample from the summit was found to be sterile and to contain considerable quantities of sulphur and chlorides. The clay size fraction showed kaolinite, a mixed layer montmorillonite-illite, illite, and feldspar. The mineral suite of these soils may have been derived in place under the action of past and present surface hydrothermal processes; alternatively, it is possible that the minerals may have been synthesised at depth in the crater and later expelled.

“…Among the most successful microscopic animals living in Antarctica are the nematodes, rotifers, and tardigrades (Convey 2010). Such microscopic animals were already known at the time of the first expeditions: ''The microscope showed that rotifers, water-bears, and other forms of minute animal-life existed'' (Shackleton 1909b). Among these microscopic animals, ''It became a contest between rotifers and scientist, and generally the rotifers seemed to triumph'' (Shackleton 1909a).…”

We present a data set on Antarctic biodiversity for the phylum Rotifera, making it publicly available through the Antarctic Biodiversity Information facility. We provide taxonomic information, geographic distribution, location, and habitat for each record. The data set gathers all the published literature about rotifers found and identified across the Continental, Maritime, and Subantarctic biogeographic regions of Antarctica. A total of 1455 records of rotifers in Antarctica found from 1907 to 2018 is reported, with information on taxonomic hierarchies, updated nomenclature, geographic information, geographic coordinates, and type of habitat. The aim is to provide a georeferenced data set on Antarctic rotifers as a baseline for further studies, to improve our knowledge on what has been considered one of the most diverse and successful groups of animals living in Antarctica.
