Abstract The terrestrial ecosystems of Victoria Land, Antarctica are characteristically simple in terms of biological diversity and ecological functioning. Nematodes are the most commonly encountered and abundant metazoans of Victoria Land soils, yet little is known of their diversity and distribution. Herein we present a summary of the geographic distribution, habitats and ecology of the terrestrial nematodes of Victoria Land from published and unpublished sources. All Victoria Land nematodes… 
A nematode in the mist: Scottnema lindsayae is the only soil metazoan in remote Antarctic deserts, at greater densities with altitude
A decrease in biodiversity and density of terrestrial organisms with increasing altitude and latitude is a well-known ecogeographical pattern. However, studies of these trends are often
Nematodes in a polar desert reveal the relative role of biotic interactions in the coexistence of soil animals
TLDR
It is found that abiotic factors alone cannot explain the data and interaction between species have been historically underestimated, whereas the role of negative biotic interactions has been largely underestimated in soil.
Biotic Interactions in Experimental Antarctic Soil Microcosms Vary with Abiotic Stress
Biotic interactions structure ecological communities but abiotic factors affect the strength of these relationships. These interactions are difficult to study in soils due to their vast biodiversity
Spatial and temporal patterns of microbial mats and associated invertebrates along an Antarctic stream
TLDR
It is suggested that, under stable flow conditions, microinvertebrate grazers could exert top-down control on microbial mat biomass, and under peak flows invertebrates decline in the microbial mats, while the sediment beneath the mats is a refuge from the flow disturbance.
Genome analysis of Plectus murrayi, a nematode from continental Antarctica
Abstract Plectus murrayi is one of the most common and locally abundant invertebrates of continental Antarctic ecosystems. Because it is readily cultured on artificial medium in the laboratory and
100 years on: a re-evaluation of the first discovery of microfauna from Ross Island, Antarctica
Abstract Over a century ago microfaunal diversity was first recorded by James Murray in lakes at Cape Royds, Ross Island, Antarctica. The report stands as the seminal study for today’s biodiversity
Stable C and N isotope ratios reveal soil food web structure and identify the nematode Eudorylaimus antarcticus as an omnivore–predator in Taylor Valley, Antarctica
TLDR
Stable isotope natural abundance ratios of C (13C/12C) and N (15N/14N) for different metazoan taxa were measured to determine soil food web structure in Taylor Valley, Antarctica and found that three trophic levels were present in wet soil habitats.

LOW‐DIVERSITY ANTARCTIC SOIL NEMATODE COMMUNITIES: DISTRIBUTION AND RESPONSE TO DISTURBANCE
TLDR
The nematode community structure of 1–3 species in two functional groups may be the simplest soil food web of any terrestrial ecosystem, suggesting that Antarctic soil ecosystems are sensitive to anthropogenic disturbance.

Nematode communities of Byers Peninsula, Livingston Island, maritime Antarctica
TLDR
Byers Peninsula is by maritime Antarctic standards, a nematode biodiversity hotspot, and the presence of several previously unrecorded genera indicates that Nematode species richness in maritime Antarctica is probably underestimated, and results indicate that abiotic factors influence nematodes communities with little evidence for biotic interactions.

Are we failing to acknowledge the impact of global changes (e.g. UVB, invasive species, climate, land use, atmosphere) on the terrestrial biodiversity and ecosystem processes of Antarctica?
Co-variation in soil biodiversity and biogeochemistry in northern and southern Victoria Land, Antarctica
TLDR
Variation in soil metazoan communities was related to differences in soil organic matter, while bacterial diversity and community structure were not strongly correlated with any single soil property, suggesting that controls over distribution and habitat suitability are different for bacterial and metazoa communities.
Diversity and biogeography of the Antarctic flora
TLDR
The Antarctic flora has been reasonably well-sampled, but certain areas require further floristic surveys, and MDS ordination suggests three major floral provinces within Antarctica: northern maritime, southern maritime and continental.
Invertebrates in ornithogenic soils on Ross Island, Antarctica
TLDR
It appears that excessive accumulations of nutrients, creating high soil salinity, may limit soil invertebrate presence within active rookeries.
Population Age Structure of Nematodes in the Antarctic Dry Valleys: Perspectives on Time, Space, and Habitat Suitability
TLDR
Temporal variation of variables describing nematodes populations in Antarctic soil suggests the nematode species respond to short-term climate variation and, thus, may be affected by long-termClimate change.
