Gippsland earthworm colonies are small and isolated, [9] and the species' low reproductive rates and slow maturation make those small populations vulnerable. [9] Their natural habitats are grasslands, and while they can survive beneath pastures, [9] cultivation, heavy cattle grazing and effluent run-off are adversarial to the species. [9]
Aridulodrilus molesworthae is a large Australian earthworm occurring, unusually, in a semiarid region of New South Wales.It was recognised as a species of Megascolecidae, a family with extreme diversity in the wetter coastal regions of the continent, but distinguished as a new monotypic genus Aridulodrilus, a name derived from Latin meaning a semi-desert worm.
Megascolecidae is a family of earthworms native to Madagascar, Australia, New Zealand, Asia, and North America. All species of the Megascolecidae belong to the Clitellata class. [2] The Megascolecidae comprise a large family of earthworms [3] and they can grow up to 2 meters in length. [4]
In Australia, changes in farming practices such as the application of superphosphates on pastures and a switch from pastoral farming to arable farming had a devastating effect on populations of the giant Gippsland earthworm, leading to their classification as a protected species. Globally, certain earthworms populations have been devastated by ...
Eisenia fetida, known under various common names such as manure worm, [2] redworm, brandling worm, panfish worm, trout worm, tiger worm, red wiggler worm, etc., is a species of earthworm adapted to decaying organic material. These worms thrive in rotting vegetation, compost, and manure. They are epigean, rarely found in soil.
Approximately 182 earthworm taxa in twelve families are reported from the United States and Canada, of which sixty (about 33%) are introduced. [4] Only two genera of lumbricid earthworms are indigenous to North America while introduced genera have spread to areas without any native species, especially in the north where forest ecosystems rely on a large amount of undecayed leaf matter.
A neurosurgeon investigating a woman’s mystery symptoms in an Australian hospital says she plucked a wriggling worm from the patient’s brain. Surgeon Hari Priya Bandi was performing a biopsy ...
The Lake Pedder earthworm (Hypolimnus pedderensis) is an extinct earthworm species in the family Megascolecidae. [1] [2] Its genus Hypolimnus is monotypic.[3]It was endemic to the Lake Pedder area in Tasmania, Australia, prior to its flooding in 1972 for a hydro-electric power scheme.
