Development Of Organic Rice Farming Might Benefit From New Species Of Semi-aquatic Freshwater Earthworms
2013-02-07 09:19:26

Pensoft Publishers The semi-aquatic earthworms in the genus Glyphidrilus are somewhat unfamiliar species that live between the terrestrial and freshwater ecosystems of rivers, streams, canals, ponds, swamps and paddy systems. Remarkably, each species is endemic to a single water basin, carrying its own signature of evolution from their common origin. A study describing ten newly discovered species of the genus has been published in the open access journal ZooKeys. In Thailand, the...

Heavy Metal Soaked Up By Earthworms

redOrbit Staff & Wire Reports - Your Universe Online Using Worms For Bioremediation Of Toxic Metals According to researchers writing in the International Journal of Environment and Waste Management, earthworms could be used to remove toxic heavy metals, including cadmium and lead, from solid waste from domestic trash collection and waste from vegetable and flower markets. Three species of earthworm, Eudrilus eugeniae, Eisenia fetida and Perionyx excavates can be used to help in...

Lee Rannals for redOrbit.com - Your Universe Online Scientists have engineered a soft autonomous robot that crawls across surfaces similar to how an earthworm moves. The robot developed by researchers at MIT, Harvard University and Seoul National University is made almost entirely of soft materials, giving it the ability to be stepped on and inch away without a dent. The "Meshworm" robot has an "artificial muscle" that was created from wire made of nickel and titanium. Researchers...

Earthworm Species Thriving In Ireland As Global Temperatures Rise
2012-07-26 07:04:21

Scientists have discovered a thriving population of Mediterranean earthworms in an urban farm in Dublin, Ireland. The findings by University College Dublin scientists published in the journal Biology Letters on 25 July 2012 suggest that rising soil temperatures due to climate change may be extending the geographical habitat range of the earthworm Prosellodrilus amplisetosus. "Soil decomposer species including earthworms are frequently introduced into non-native soils by human activities...

Much like the fabled tortoise and the hare, the competition between native and invasive plants growing in deciduous forests in the Eastern United States is all about how the plants cross the finish line in autumn. A new study by a Syracuse University biologist has found that the leaves of invasive plants continue to function in the fall, long after their native cousins have hunkered down for the winter. The findings are counter to conventional wisdom, which held that plants living under...

A recent decline in ovenbirds (Seiurus aurocapilla), a ground-nesting migratory songbird, in forests in the northern Midwest United States is being linked by scientists to a seemingly unlikely culprit: earthworms. A new survey conducted in Minnesota's Chippewa National Forest and Wisconsin's Chequamegon-Nicolet National Forest by a research team led by Scott Loss of the University of Minnesota and the Smithsonian Migratory Bird Center has revealed a direct link between the presence of...

Invasion Of The Earthworms
2011-09-12 09:22:21

  Non-native earthworms are damaging hardwood forests [ View the Science Nation Video ] Think of earthworms and a few things come to mind: they make great bait for fishing, they aerate the soil, and they're an excellent addition to a compost pile. But what a lot of people don't know is many earthworms are actually invasive species. "The western Great Lakes region, which is the area we're focused on, has no native earthworms," says ecologist Cindy Hale, a research associate...

Study shows humans to blame for spread of non-native species It is widely acknowledged that human beings are largely responsible for the widespread alteration of ecosystems on the planet. A recent study by Dara Seidl and Peter Klepeis of Colgate University in New York traces the ways in which humans are the principal agents of dispersal of exotic earthworms in the forests of Northern America. Their findings, published online in Springer's journal Human Ecology, suggest that humans spread...

A new study has found that an emerging tool for combating climate change may cause less harm to some soil animals than initial studies suggested. Earthworms perform many essential and beneficial functions in the soil ecosystem, including soil structure improvement and nutrient mineralization. However the earthworms' ability to perform these crucial functions can be suppressed when they are exposed to toxic substances. A Baylor University geology researcher, along with scientists from Rice...

Nightcrawler, Lumbricus terrestris
2014-01-12 00:00:00

The nightcrawler (Lumbricus terrestris), also known as the lob worm or the common earthworm in Britain and the dew worm in Canada, is a species of earthworm that is classified within the Annelida phylum. It is native to Europe, but has been introduced into other areas around the world. Although the species is not as abundant as other worms in its range, it is a widely known species in gardens of temperate habitats, where it moves about on the surface of the soil. The nightcrawler can reach...

Red Earthworm, Lumbricus rubellus
2014-01-12 00:00:00

The red earthworm (Lumbricus rubellus) is a species of earthworm that is classified within the Annelida phylum. It is native to the British Isles and Europe, but has traveled across the world to areas with appropriate habitats. This worm prefers to reside in soil that contains high organic matter content, like feces, but it needs loose soils in order to move about and feed. The sustainability of a habitat depends upon factors such as the PH balance of the soil, moisture levels, temperature,...

Redworm, Eisenia fetida
2014-01-12 00:00:00

The redworm (Eisenia fetida), also known as the brandling worm, the tiger worm, the panfish worm, the trout worm, or the California worm, is a species of earth worm that is classified within the Annelida phylum. This species is native only to Europe, but it has been introduced into every country, excluding Antarctica, for vermicomposting purposes. Unlike other species of worm, the redworm does not prefer to reside in soil. It can be found in manure, rotting vegetation, and compost. The...

Vermicompost
2013-03-20 16:04:22

Vermicompost is composting with the use of special earthworms. Red wigglers and white worms are the more common worms used, although European night crawlers can be used as well. Red wigglers can be found living in manure piles and in rotting vegetation and adapt the best in covered worm bins. Common earthworms burrow deeply and are not recommended for use in compost bins. Blue worms are commonly used in the tropics. Worms are used to decompose vegetable and food waste along with bedding...

Southern African Hedgehog, Atelerix frontalis
2012-10-01 10:25:35

The southern African hedgehog (Atelerix frontalis) can be found in many areas of Africa including Angola, Lesotho, South Africa, and Zimbabwe. It prefers a habitat in areas that are slightly damp, with abundant vegetation, although it can live in many different habitats. It is nocturnal, spending most of the day resting under leaves and other debris, holes, or bushes. These areas are not permanent, but breeding nests and some winter nests are used semi-permanently. The southern African...
