Australian Earthworms as a Natural Agroecological Resource
Bibliographic record
Abstract
Australia has an unrealized natural resource in its unprecedented diversity of earthworms. Surveys on the ground and of the literature give an overall total for Australian and Tasmania combined of 715 species and sub-species in 73 genera and ten families comprising 650 endemic natives, wholly adapted to Australian climates and soils, and 65 (ca. 9%) exotic interlopers that tend to be less specialized but more widespread. Of the exotics, only one third, just 3% of total species, are lumbricids of the holarctic family Lumbricidae. If Australia's neo-endemics and translocated natives are included as non-natives, it raises their numbers above 80 species – considerably higher than a previous “National Survey” estimate of just 27 species. Compared to any other region, the earthworm fauna of Australia is diverse (cf. India/Sri Lanka – 350 spp, New Zealand – 200 spp; USA/Canada – 180 spp; USSR – 113 spp; Amazonia – >120 spp; British Isles – 69 spp) and, as much of the continent has yet to be systematically surveyed, it is anticipated that the tally of both natives and exotics will continue to grow Earthworms are vital for sustainable primary production and waste management, yet only slowly do we gain an ecological appreciation of their potential to benefit Australia's natural environment. Trials and experiments in Australia have tended to mimic those conducted overseas, especially in Europe, using a limited range of exotic species, with similarly variable results and have largely overlooked native species. A long-term publicly funded project to import the exotic Aporrectodea longa from Tasmania to the mainland was somewhat compromised from the outset by the well-documented prior occurrence, not only of this species but also of many other ‘deep-burrowing’ species, on the mainland. However, it now seems that modifying soil to maintain or enhance conditions favourable for resident populations to recolonize and expand may prove the most beneficial option for both worm and farmer. Appropriate management strategies are briefly presented.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
