Abstract:

Burrows resulting from earthworm activity are important for supporting various physical and ecological soil processes. Earthworm burrowing activity is quantified using models for earthworm penetration and cavity expansion that consider soil moisture and mechanical properties. Key parameters in these models are the maximal pressures exerted by the earthworm's hydroskeleton (estimated at 200 kPa). We designed a special pressure chamber that directly measures the pressures exerted by moving earthworms under different confining pressures to delineate the limits of earthworm activity in soils at di

Abstract:

To test whether invasion of exotic earthworms affects soil carbon (C) and nitrogen (N), we sampled the litter and upper mineral soil (to 30 cm) at a series of sites varying in their earthworm populations in an old-growth beechmaple forest at Mont St. Hilaire, southern Quebec. We measured earthworm abundance and biomass using hand-sorting and chemical extraction (allyl isothiocyanate) methods. They gave similar results, though there was evidence of size and species-specific biases. Abundance and biomass of the earthworms ranged from <10 to >100 earthworms·m2 and from <10 to 125 g·m2

Abstract:

Agriculture is the main contributor to nitrous oxide (N2O) emission, but the emission intensity can be controlled by various factors, in particular, the activity of earthworms, one of the most common groups of soil invertebrates. We conducted an incubation experiment to evaluate N2O emission in earthworm soil samples compared to non-earthworm ones with applications of high (200 kg ha−1) and low (50 kg ha−1) mineral N fertilizer doses. We assessed the cumulative N2O emission, the dynamics of the soil dissolved organic carbon, and the soil microbial carbon and nitrogen content, as well as the nu

The paper reviews knowledge on earthworms from early classical times to the end of the seventeenth century.

Aldrovandi and Mouffet presented field observations of sexual reproduction and specific habitat requirements. Willis demonstrated the complex internal anatomy of an earthworm. Finally Redi, based on numberless dissections, showed the existence of variations on that bas

Abstract:

Non-native earthworms can cause abrupt changes in forest ecosystems by altering soil properties and depleting or redistributing soil carbon (C) stocks. The forests of Northern Maine are often perceived as having winters that are too harsh to support earthworm populations and that earthworms are restricted to more southerly regions. In this study, we report the discovery of European earthworms at two research sites in Northern Maine. At one site, earthworms were only found across a portion of the forest, and the median organic (O) horizon C stock in the area with earthworms was 34% less than th

The earthworms’ abundance is usually one of the main indicators of healthy and productive soils. However, agricultural management practices affect the earthworm population and activities.

Thus the current study was done to determine the effects of long-term tea cultivation on the earthworm’s population and abundance in the tea plantations of Iran to distinguish effects of these practices on soil properties con

Vermicomposting is a process that involves biological, chemical and physical transformations of solid organic materials such as agricultural residues of plant and animal through the use of microorganisms and earthworms.

In addition, the effects of a diet in which fish meal was substituted with EM or fresh earthworms on the health and productive performance of broilers were monitored. The experiment, which lasted 42 days, was conducted on one hundred Hybro G broilers divided into four equal groups. The control group was fed a standard feed, whereas, the first and the second one were given diets in which 50% or 100% of fish meal had been substituted with

Abstract:

The impact that plant communities may have on underground faunal diversity is unclear. Therefore, understanding the links between plants and organisms is of major interest. Earthworm population dynamics were studied in the pineapple agroecosystems of Tripura to evaluate the impact of monoculture plantation on earthworm communities. A total of thirteen earthworm species belonging to four families and five genera were collected from different sampling sites. Application of sample-based rarefaction curve and nonparametric richness estimators reveal 90–95% completeness of sampling. Earthworm commu

Abstract:

With the forecasted dramatic growth of insect rearing in the near future, frass (insect excreta) has been increasingly considered a sustainable resource for managing plant nutrition in cropping systems and a promising alternative to conventional fertilizer. However, the impact of soil fauna on its fertilizing effect has not been investigated so far. In this study, we investigated the effect of earthworms (Lumbricus terrestris L.) on nitrogen (N), phosphorus (P), potassium (K) and calcium (Ca) uptake and crop growth in the presence of frass from mealworm (Tenebrio molitor L.).

Abstract:

Earthworms have a role as bioindicators so that their existence is very sensitive to changes in the environment. The decreasing of land quality caused by continuous use (horticultural agriculture) will also decrease the diversity of earthworms. To anticipate degradation of land quality, the land needs to be rested (bero) so that it will facilitate natural recovery. Indicators of land restoration include the diversity and importance index of earthworms. Therefore, the research aim was to determine the diversity of earthworm in the fallow system lands at Kelimutu National Park areas. The monolit

Abstract:

Methane (CH4) is one of the major greenhouse gases that significantly contributes to global warming. Therefore, substantial efforts are being made to reduce CH4 emissions. Paddy fields make a major contribution to atmospheric CH4 concentration because of their anoxic soil environment. Paddy field is habitat of many aquatic earthworms which can play a crucial role in reducing CH4 emissions from paddy field, because their bioturbation activities influence the soil structure and increase oxygen penetration and hence the activity of methanotrophs. Therefore, it was hypothesized that aquatic earthw

Earthworms in forests ensure the return of nutrients to the soil by recycling litter. Climate warming promotes changes in the feeding ecology of earthworms, which leads to changes in soil nutrient cycling due to the saturation of biotopes with invasive plants and lumbricids. This study explored the use of mid-infrared (IR) spectrometry as a technique for identifying earthworm dietary preferences. In a controlled laboratory-based experiment, we examined how consumption of three different types of leaf litter — Populus tremula, P. sibirica, and Acer negundo — affects the IR spectra of three eart
