Earthworms in the Urban Environment: Can Population Augmentation Improve Urban Soil Properties?
… is often degraded by human activity. Because earthworms play a key role in soil health, augmenting earthworm populations in urban soils may improve tree performance. However, we know very little about earthworm ecology in highly urbanized soils. The objectives of our study were: (1) to assess …

Species and Cultural Management of Earthworms on Golf Course Turf in Arkansas and Oklahoma
<p>As earthworms feed, they can egest soil and nutrient-rich aggregates (casts) on the soil surface. In low-cut turfgrass systems, such as golf course greens, tees, and fairways, surface casting can result in a muddy playing surface, ball roll issues, weed and pest invasion, reduced aesthetics, …

The Effects of Musical Intervals from Consonant to Dissonant on the Neural Activity of Earthworms
<p>Music is generated through vibrations of a medium creating what is perceived as tone. Two frequencies played simultaneously create intervals, and those ratios of frequencies determine what is consonant and dissonant. Studies have shown a greater neural response in human participants to consonant …

Dead dogs, electrified earthworms and restrained ruminants: student opinion on animal use in preclinical veterinary education
… of dead animals to dissect in anatomy, with live earthworms on which to experiment in physiology classes, and with farm animals used again and again by multiple students to practice handling techniques. They will work on farms in their vacations where the standard of animal welfare may not be what …

Interactions of insecticides, entomopathogenic fungi, and earthworms as they relate to white grub IPM in turfgrass systems
… their effects on other soil organisms such as earthworms, which cohabitate with white grubs in turfgrass soil ecosystems. Herein, I investigate the following: 1) the efficacy of combined applications of the EPF, M. brunneum and B. bassiana with lower rates of imidacloprid or the diamide …

Denitrification, Dissimilatory Nitrate Reduction, and Methanogenesis in the Gut of Earthworms (Oligochaeta): Assessment of Greenhouse Gases and Genetic Markers
… no N2O, leading to the hypothesis that large earthworms cannot emit nitrogenous gases, i.e., N2O and N2. There was no emission of the greenhouse gas CH4 reported for earthworm species. The current study analyzed ten earthworm species of different families, sizes, and feeding guilds (i.e., …

Chemesthesis in the Earthworm, Lumbricus terrestris: The search for TRP Channels
… there are no reports of TRP channels in earthworms. Earthworms, including Lumbricus terrestris, aerate and enrich soil providing a suitable habitat for plants. Hence, chemicals in the soil which repel earthworms could have deleterious effects on plant growth. Allyl isothiocyanate, a …

Interactions with earthworm communities: a laboratory-based approach with potential applications for soil restoration
The role of earthworms in improving soil fertility and structure is widely recognised. As a result earthworms (often single species populations) have been deliberately introduced into pasture and arable land by man in attempts to improve plant production and into degraded land in order to bring …

Short Rotation Forestry and Earthworm Diversity: Impacts and Responses
… the earthworm community is a major component. Earthworms have direct impacts on the soil biogeochemistry of SRF systems, and the tree species can impact on the associated earthworm community. The aim of this study was to investigate the effects of SRF species and litter quality on earthworm …

Eisenia hortensis Detects Chemesthetic Irritants through TRP Channels
Earthworms have large impacts on the environment they inhabit. Through their movement, they assist in aerating the soil as well as increasing soil permeability to water which can increase plant growth. Despite their importance to agriculture, little is known about earthworm chemesthesis i.e., the …

Quantificação de coprólitos de minhocas nativas em latossolo amarelo cultivado com braquiárias na ausência e presença de adubação mineral
… Samples were collected in coprolites produced by earthworms, every 35 days, thus totaling ten collected, being five in the rainy season and the five dry season for a year. Besides the quantity of coprolites produced, were made to determine the quality of the coprolites through physical analysis …

Influence of copper on resistance of Lumbricus terrestris to bacterial challenge
Earthworms, Lumbricus terrestris, were challenged orally and intracoelomically with two bacterial species, Aeromonas hydrophila and Pseudomonas aeruginosa, and mortality rates were observed. Neither were found to be particularly pathogenic at injected doses of up to 108 bacteria per earthworm. The …

The Detoxification of Petroleum Contaminated Coastal Plain Sandy Soil Using an Amended Vermicomposting Approach
… consisted of the addition of 30 Eisenia foetida earthworms and distilled water. Treatment 3 consisted of direct application of liquid municipal biologic sludge and 30 Eisenia foetida earthworms. The experimental findings showed the greatest reduction in Total Petroleum Hydrocarbon (TPH) …

The effect of reduced cultivation on selected soil fauna
… the effects of reduced cultivation techniques on earthworms and epigeic fauna in general, and on carabids and staphylinids in particular. Two separate farms were sampled. The first, Drayton Experimental Husbandry farm in Warwickshire, had a fully replicated bock design layout of three types of …
