Terrestrial arthropods that reside in Antarctica are exposed to considerable periods of environmental stress, thus factors that promote identification of favorable microhabitats are extremely important. In this study, we report the presence of chemical cues that induce oviposition and aggregation in two species of Antarctic collembolans, Cryptopygus antarcticus and Friesea grisea. Responses of the Collembola were enhanced by low temperatures but were not altered by humidity. One of the major…

Chemical Attraction of Conspecifics in Folsomia candida (Collembola)
Chemical substances excreted from individuals are regarded as chemo-sensory signals that induce aggregation in Collembola. However, chemical or physiological evidence is required to identify the…
Chemical communication in springtails: a review of facts and perspectives
TLDR
Much more needs to be done before reaching straightforward conclusions about chemical communication issues at evolutionary and community levels, making this domain even more rewarding.
Micro-terraforming by Antarctic springtails (Hexapoda: Entognatha)
TLDR
By-products of moulting behaviour representing the first tangible evidence of environmental modification by terrestrial invertebrates on the Antarctic continent contribute to primary soil formation processes through the structural cohesion of particulate matter.
Is ornithogenic fertilization important for collembolan communities in Arctic terrestrial ecosystems?
TLDR
This study focused on springtail community composition in the vicinity of seabird nesting areas in different parts of Svalbard on their comparison with adjacent areas not impacted by seabirds.
Move or change, an eco-evolutionary dilemma: The case of Collembola
Cuticular Compounds Bring New Insight in the Post-Glacial Recolonization of a Pyrenean Area: Deutonura deficiens Deharveng, 1979 Complex, a Case Study
TLDR
The discriminating power of cuticular compounds is directly related to their involvement in sexual attraction and mate recognition and this character type brings the first advance from pattern to process concerning the origin of this species complex in the Pyrenean zone.
Age and level of self-organization affect the small-scale distribution of springtails (Collembola)
TLDR
It is shown that two coexisting species with clear aggregation patterns greatly differ in how much the environment contributes to affecting the species' spatial structure, which has implications for the general predictability of changes in spatial structuring of species.
Native terrestrial invertebrate fauna from the northern Antarctic Peninsula: new records, state of current knowledge and ecological preferences - Summary of a German federal study
TLDR
While no new endemic species were identified among the microarthropods (Collembola and Acari), several nematode taxa were found that are probably new to science.
Relationships of some environmental variables to the aggregation patterns of soil microarthropod populations in forests
Different-scale distribution of Collembola in homogenous ground vegetation: Sphagnum moss
TLDR
Patterns of spatial distribution of Collembola were studied in sphagnum pine forests (Karelia, northwest of European Russia) in habitats of the same type using plots varying in area from 1 dm2 to 100 m2 and shown to be species-specific and constant in time and space.

Extremely large aggregations of collembolan eggs on Humble Island, Antarctica: a response to early seasonal warming?
TLDR
This early warming and consequent extended period of relatively high temperatures may have modified thermal and hydric conditions favoring collembolan growth and development and the formation of these large aggregations.
Life cycle strategies in two Antarctic Collembola

  • Environmental Science

  • 2004
TLDR
Analysis of gut contents showed that the two species overlapped in their food range; the faster growth of P. octooculata being achieved by a faster consumption rate, since the twospecies had similar assimilation and production efficisation.
Feeding and Growth in the Antarctic Collembolan Cryptopygus Antarcticus
TLDR
Variations in the rate of moulting and of faecal pellet production by Cryptopygus antarcticus (Willem), collected from Signy Island in the maritime Antarctic, were rheasured, suggesting cold adaptation of its moults behaviour.
Rafting in Antarctic Collembola
TLDR
It is suggested that moult exuviae facilitate survival on the water film through the simultaneous provision of a flotation aid and a source of nourishment – that is, an ‘edible raft’.
Formation and ecological significance of aggregations in collembola
SummarySpatial distribution in the two collembolan species Tomocerus minor and Orchesella cincta is greatly influenced by the distribution of the environmental factors water and food. T. minor is…
Habitat moisture availability and the local distribution of the Antarctic Collembola Cryptopygus antarcticus and Friesea grisea
Influence of temperature on the hygropreference of the Collembolan, Cryptopygus antarcticus, and the mite, Alaskozetes antarcticus from the maritime Antarctic.
Aggregation promotes water conservation during diapause in the tropical fungus beetle, Stenotarsus rotundus
TLDR
Net transpirational water loss is measured in beetles from aggregations of different sizes to test the possibility that aggregation may influence the microclimate and contribute to water conservation.
Aerial dispersal of springtails on the Antarctic Peninsula: implications for local distribution and demography
TLDR
This is the first study to demonstrate conclusively the survival of wind-borne native arthropods within Antarctica, and uses known desiccation rates of C. antarcticus and wind speeds to predict the likelihood of successful dispersal between the principal terrestrial habitats of the larger Marguerite Bay.
Temperature preferences of the mite, Alaskozetes antarcticus, and the collembolan, Cryptopygus antarcticus from the maritime Antarctic
TLDR
Alaskozetes antarcticus appears more influenced by temperature, especially during regular freeze‐thaw transitions, when this species may select low temperature microhabitats to maintain a cold‐hardened state and Cryptopygus antarcticaus appears better able to opportunistically utilize developmentally favourable thermal microclimates, when moisture availability is not restricted.
