Adaptation Of Earthworms And Other Organisms To Soil Constraints The Power Of Mutualism

Small microflora and microfauna (< 0.2 mm on average) live in the water-filled soil pores. They mostly comprise bacteria, fungi, protists, and nematodes. Their capacity for movement is limited, and they have developed highly effective mechanisms for resisting dessication. Meso-faunal invertebrates (0.2 to 2 mm on average) live in the air-filled portion of soil pores and litter layers. Earthworms and a few other groups of larger soil invertebrate ecosystem engineers have the ability to dig the soil. This allows them to move freely by digging burrows and galleries Invertebrates seem to have rather limited proper digestive capabilities. A few studies demonstrate that part of the digestive enzymes present in their guts have been actually produced by microorganisms. This is the case for earthworms that have developed mutualist digestion systems in association with free-soil bacteria, as hypothesized by Lavelle et al. 1995 (also see Zhang et al. 1993, Lattaud et al. 1999, and Garvin et...

The Drilosphere As A Selforganizing System

Earthworms and other major soil ecosystem engineers create physical domains in soils that have all the characteristics of self-organized systems as defined by Perry (1995) Based on strong and rather specific interactions within physical boundaries, these systems change the constraints of their environment with positive feedbacks on their own living conditions (Lavelle et al. 2006 see Figure 5.1). Soil constraints indeed have pushed soil organisms to develop intense interactions along evolutionary time, mostly of a mutualistic type (Lavelle and Spain 2006). These interactions operate within the boundaries of the rhizosphere of roots, drilosphere of earthworms, and termitosphere of termites, as well as a few other such domains (Lavelle 2002) that have FIGURE 5.1 A general model of the drilosphere system. Within the boundaries (large dotted line) of their functional domain, the drilosphere, earthworms accumulate macro aggregates, galleries, and other pores that constitute the habitat for...

Harnessing The Drilosphere To Restore Ecosystem Functions In Degraded Soils

Drilospheric effects on plant growth and health and on soil physical properties are much better understood. Earthworms are legitimately considered important actors in the maintenance of adequate hydraulic properties in the upper 20 cm of soils, where infiltration and most detoxification processes operate. For these reasons, earthworms and their drilospheres long have been recognized as useful resources, and the potential for their management in agroecosystems is vast and diverse (Lavelle et al. 1999, Jimenez and Thomas 2001). Soil degradation is most often associated with a depletion in biodiversity and abundance of earthworm and other invertebrate communities. Earthworms are greatly sensitive to land use intensification at plot and landscape levels. Ploughing and pesticide applications are especially harmful to them (Edwards and Bohlen 1996). Conversion of forests to pastures and cropped land and habitat fragmentation may eliminate a large proportion of native species where they...

Typical Pathogen Levels in Wastewater Sludges

As shown by the values in Table 3.10, the pathogen levels in raw and digested sludge can be quite high. The pathogen content of sludge is especially critical when the sludge is to be used in agricultural operations or when public exposure is a concern. The sludge utilization guidelines developed by the U.S. EPA are discussed in detail in Chapter 9. Sludge stabilization with earthworms (vermi-stabilization) is also described in Chapter 9, and some evidence suggests that a reduction in pathogenic bacteria occurs during the process. The freeze-dew-atering process will not kill pathogens but can reduce the concentration in the remaining sludge due to enhanced drainage upon thawing. The reed-bed drying concept can achieve significant pathogen reduction due to desiccation and the long detention time in the system. Pathogens are further reduced after sludge is land applied, by the same mechanisms discussed previously for land application of wastewater. There is little risk of transmission of...

Agricultural Disturbances

The successional status of a soil community may also reflect the history of disturbance. Succession in cropped agricultural fields begins with depauperate soil which acts like an island to which a series of organisms immigrate. First, opportunistic species, such as bacteria and their predators, are colonists of soil. Subsequently, fungi and their predators migrate into the area (Bostrom and Sohlenius, 1986). Microarthropods, such as collembolans, mites, and fly maggots, can colonize nearly bare ground and rise quickly in population density. Top predator microarthropods, such as predaceous mites and nematodes, become established later and may have a function similar to keystone predators in other community food webs (Elliott et al., 1988). Finally, macro- and megafauna, such as earthworms, millipedes, slugs, centipedes, wood lice, sow bugs, and pill bugs, join the soil community (Strueve-Kusenberg, 1982).

David R Montgomery Darlene Zabowski Fiorenzo C Ugolini Rolf O Hallberg and Henri Spaltenstein

Plants and animals disrupt and disaggregate rocks and fracture or abrade individual grains or minerals. Endolithic algae growing in deserts may be capable of disintegrating rocks through shrinking and swelling (Friedman, 1971). Lichens are effective agents in physical weathering by extending fungal hyphae into rocks and by expansion and contraction of the thalli (Syers and Iskandar, 1973). Higher plants grow roots in rock crevices and eventually the increased pressure breaks and disrupts the substratum. In addition, the physical mixing of rock and soil that occurs from tree throw is a primary process in the conversion of bedrock into soil in forested regions. Earthworms, as discussed by Darwin (1896), digest and abrade a considerable amount of soil. Mammals, such as moles, gophers, and ground squirrels tunnel and excavate a substantial amount of soil when they build dens (Black and Montgomery, 1991 Butler, 1995). Similarly, rodents break down rocks and create fine particles (Ugolini...

Agricultural intensification

The key factors determining total biodiversity in the different agroecosys-tems shown in Figure 11.2 are microclimate, habitat structure and food resources. Hence forest plantations and home gardens retain many of the community characteristics of natural forest, and pasture communities are functionally similar to savannas. The pattern of species losses in the soil biota along the gradient of agricultural development approximates that of Curve IV in Figure 11.2. The point of inflection from more to less diverse communities varies, however, for different sizes and functional groups according to the type of farming system and agricultural practice. In the extreme situation of direct conversion of forest to intensive cultivation of short-rotation crops, there is rapid disappearance of surface-active macro-invertebrates (millipedes, earthworms, beetles) which use leaf litter as both a habitat and a food resource (Lavelle et al. 1994). As the mass of soil and litter organic matter pools is...

Lessons From Disparate Engineers

First, one distinct benefit in considering many different ecosystem engineers in side-by-side case studies is the identification of the unique advantages that different systems may offer for examining different lines of research questions. For example, the shelter-building insects described by Lill and Marquis (Ch 6) and the soil-tilling earthworms described by Lavelle (Ch 5) clearly alter the physical structure of habitat in important Generalizing types of ecosystem engineering would greatly aid such a development of a full theoretical and conceptual treatment because one of the impediments may be that each case of ecosystem engineering has been viewed as idiosyncratic, to be addressed on a case-by-case basis. In describing the paleo explosion of bioturbators-aerators as an important, engineering life form, Marenco and Bottjer (Ch 8) have provided an example of how we could meaningfully categorize engineers according to their functional alterations of the environment. Examples of...

Relationships Between Biodiversity And Function In Agroecosystems

Magnitude of local effects created by the individual within the spatial and temporal patterns of the species population in the system. The functional properties of individual species are therefore determined by the body size and activity of individuals, and the density and aggregative characteristics of the population. In the case of soil organism communities, for example, eollembola or mite species, feeding on fungi and bacteria at a scale of millimetres or less, form aggregations affecting microbial processes within a volumetric decimeter or more earthworms, forming burrows of a few millimetres in diameter, have aggregative effects on hydrologic processes in patches of several metres fungal hyphae, active at the cellular level, can be a component of a single genetic individual dominating wood decomposition over many hectares with a biomass of tonnes littcr-feeding termites (Macro-terminae) determine soil physical and chemical processes from the plot to landscape scale (Anderson...

Changes During Conversion

Microbial biomass and respiration rate were more sensitive to changes in soil management practices than total C and N. In the first 2 years, the organic management was most effective in enhancing soil microbial biomass C and N among the transition strategies, but was accompanied with high yield losses. By the third year, soil microbial biomass C and N in the reduced-input transition strategies were statistically significantly greater than those in the conventional. Soil microbial respiration rate and net N mineralization in all transitional systems were statistically significantly higher than those in the conventional, with no differences among the various transition strategies. The study suggested that the transitional strategies that partially or gradually reduce conventional inputs can serve as alternatives that could potentially minimise economic hardships as well as benefit microbial growth during the early stages of transition to organic farming systems (Tu et al. 2006). Axelsen...

Natural Systems Agriculture

Despite the enormous problems presented by chemical contamination and fossil fuel dependency, the most serious problem for the long-term sustainability of agriculture is soil loss. Soil erosion is the primary conservation problem on much of U.S. cultivated cropland, and occurs mostly during short intervals of heavy rain or high wind and when the surface is not protected by a mulch or crop canopy (Larson et al., 1997). During the last few decades, about one third of the world arable land area has been lost through soil erosion, and this loss continues at an estimated annual rate exceeding 10 million ha year (Pimentel et al., 1995). On average, soil on about 90 of U.S. cropland is being lost faster than it is being formed. Because the effects of erosion on some soil physical attributes are irreversible, erosion rates alone may not be good indicators of soil degradation and, consequently, soil quality can decline faster than the erosion rate. Once virgin soil is cultivated, organic...

Invasive Species Exotic Earthworms 4 Introduction of earthworms into forest soils has been shown to increase the diversity of fungi in burrow walls (Tiunov & Dobrovolskaya 2002), but can also have an effect on mycorrhizal colonization and, hence, potentially fruiting bodies (Lawrence et al. 2003). 17 Interaction not investigated, but evidence suggests that earthworms may help break down waste. Reclamation engineers use the viability of earthworms as an index of soil condition. 26 Earthworms contribute to soil structure through bioturbation and redistribute organic materials over a large vertical range in the soil profile however, as invasives they displace enchytraeids and microarthropods that are also critical for soil structure and development.

Effects on Other Organisms

Pp. hermophrodita is considered as a lethal parasite for slugs, however, its affect on non-target organisms has not been extensively studied. Whatever, the information available makes the evidence clear that this nematode is safe for non-target snails, beneficial predators and earthworms. Under laboratory condition, the exposure of two snails, Cepaea hortensis and Monancha cantiana, to Pp. hermaphrodita showed susceptibility in snails, but no effect was found under field condition (Wilson et al. 2000). Morley and Morritt (2006) studied the effect of Pp. hermaph-rodita upon the two fresh water snails Lymnaea stagnalis and Physa fontialis at 'spray tank' concentration and a 50 diluted 'spray tank' concentration over a period of 14 days. A significant mortality in L. stagnalis was found at both application levels, however, Pp. fontialis was unaffected. When bioassay of Pp. hermaph-rodita was conducted against tenebrionid beetles Zophoba morio and Tenebrio molitor it was found that the...

Procedures and Performance

At an operation in Lufkin, Texas, thickened (3.5 to 4 solids) primary and waste-activated sludge are sprayed at a rate of 0.05 lb ft2-d (0.24 kg m2-d) dry solids over beds containing worms and sawdust. The latter acts as a bulking agent and absorbs some of the liquid, assisting in maintaining aerobic conditions. An additional layer of sawdust, 1 to 2 in. (2.5 to 5 cm) thick, is added to the bed after about 2 months. The original sawdust depth was about 8 in. (20 cm) when the beds were placed in operation. The mixture of earthworms, castings, and sawdust is removed every 6 to 12 months. A small front-end loader is driven into the bed to move the material into windrows. A food source is spread adjacent to the windrows, and within 2 days essentially all the worms have migrated to the new material. The concentrated worms are collected and used to inoculate a new bed. The castings and sawdust residue are removed, and the bed is prepared for the next cycles. Human pathogen reduction in a...

Cascading Effects of Deforestation on Ecosystem Services Across Soils and Freshwater and Marine Sediments

Deforestation Effects Pictures

Soils with mull humus typically form on calcium-rich, moderately or well-drained clayey parent material, generally beneath grassland and deciduous forest. The mull humus form is often mildly acidic, due to leaching of base cations (e.g., calcium) down the soil profile, and is characterized by intimate mixing of the surface organic and upper mineral A horizon. This mixing results from a high abundance and activity of soil biota, especially earthworms, and also leads to enhanced rates of decomposition, nutrient availability, and plant growth. In contrast, in coniferous forests and other systems that produce poorer litter quality, there is an obvious build-up of organic matter at the soil surface the so-called mor humus. These mor humus forms are typically acidic in nature and are characterized by low rates of decomposition and plant nutrient availability, differing both biologically and chemically from the mull form. Biologically, it is typical for the microbial biomass of these mor...

Ecocide And Modern Warfare

It was not until the US-Vietnam conflict, however, that an offensive army utilized deliberate large-scale ecologically destructive technologies.30 Carrying 20 tons of bombs into the stratosphere, a US B-52 bomber could strike from 30,000 feet without warning, turning entire villages into sudden eruptions of flaming sticks, human limbs, and thatch. A formation of B-52s could obliterate a box approximately five-eighths of a mile wide by 2 miles long. These flying behemoths dropped 13 million tons of bombs on North and South Vietnam, Cambodia, and Laos - triple the total tonnage dropped in World War II. Such ferocious carpet-bombing, as historian William Thompson notes, left at least 25 million craters - each averaging 60 square yards - in a country nearly the size of Washington state. When the tropical rainforest canopy - up to 50 feet thick - resisted the onslaught of bombs, shells, and bullets, US forces developed the 15,000-pound Daisycutter bomb, which exploded with a shock-wave...

Importance of Indigenous Soil Knowledge in Developing Sustainable Agriculture

The presence of earthworms, plant residues, roots, and darker soil color In Indonesia, farmers recognize various fallow species that are used as indicators of soil fertility during the process of shifting cultivation. For example, C. odorata (Fig. 11.1) and Wedelia trilobata (Fig. 11.2) are considered indicator of better soil fertility compared to Saccharum spontaneum (Fig. 11.3) and Imperata cylindrica (Fig. 11.4) (Handayani et al. 2006). Ants are also used as indicators to show that the soil is unfertile, however, earthworms are an indicator of good soil for farming. Clay soil is considered good for cultivating paddy rice, and organic soil provides the ideal growth medium for oil palm trees (Handayani and Prawito 2008).

The Nature And Function Of Biodiversity In Agroecosystems

Agroecosystem

Biodiversity refers to all species of plants, animals, and microorganisms existing and interacting within an ecosystem. In agroecosystems, pollinators, natural enemies, earthworms, and soil microorganisms are all key biodiversity components that play important ecological roles, thus mediating such processes as genetic introgression, natural control, nutrient cycling, decomposition, etc. (Figure 2). The type and abundance of biodiversity in agriculture will differ across agroecosystems which differ in age, diversity, structure, and management. In fact, there is great variability in basic ecological and agronomic patterns among the various dominant agroecosys-tems. In general, the degree of biodiversity in agroecosystems depends on four main characteristics of the agroecosystems (Southwood and Way, 1970)

Discussion and Conclusions

The role of soil organisms is more prominent in grasslands (especially natural ones), forests, and low-input (no-till) arable land than in intensively managed grasslands and arable land. However, the relative importance of soil organisms for the performance of ecosystem processes (as compared with the importance of abiotic influences) differs along climatic gradients or between soil types. There are also differences between the relative contributions of different taxa of soil organisms to ecosystem processes along climate gradients or between soil or vegetation types. In cold areas, for example, soil microorganisms play a lesser role in the decomposition of organic matter, whereas soil fauna have a more dominant role. Earthworms are key species in mesic grasslands, but enchytraeids are crucial in coniferous forests and some arable land. There are clearly management trade-offs for the role of soil organisms in the delivery of ecosystem goods and services. We do not have much evidence...

Gwp Analysis For Conventional And Notillage Maize Production In The United States

It is also important to recognize that soil physical and biological properties are dynamic for many years following a shift from CT to NT. Soil physical conditions improve considerably with time, and the reestablishment of macro fauna, especially earthworms, leads to the development of macropore channels and much improved drainage. Organic matter and biological activity are concentrated close to the soil surface where gas exchange with the atmosphere is most rapid, promoting aeration of soils but also emission of N2O when it is being generated. It is probable that N2O emissions change over time after adoption of NT. Initially they are greater than for CT, as soils have poor structure and are poorly drained, but later they may become similar to or even less than CT as soil structure and drainage improve. Unfortunately, there has not been any systematic study of temporal effects of changing from CT to NT on N2O emissions from soils.

Applications

Organic fertilizers, especially straw and animal manures, are more similar to natural organic substrates than chemical fertilizers. Microbial and protozoan activity is highest in organically enriched soils (Schnurer et al., 1985 Aescht and Foissner, 1991 1992), and is usually accompanied by increases of most soil fauna, especially earthworms (Doran and Werner, 1990), which enhance protozoan biodiversity. The higher protozoan activity in soils under nontillage and organic fertilizer management is enhanced by other fauna, especially earthworms, which disperse bacteria and their protozoan predators to new locations, through burrowing movements and passing ingested cysts through guts, providing new hot spots and releasing greater quantities of nutrients, which have led to increased plant yields in a few cases (Brown, 1995). Ingested active protozoa furnish a highly assimilable food source, sustaining the fauna that enhance microbial and protozoan activities (Brown, 1995). Thus, high...

Conclusion

The recognition that earthworms are key operators of self-organized systems (SOS) in soils has important theoretical and practical implications. As regards soil ecology theory, we found a clear correspondence between the main characteristics of drilospheres and those of SOS as precisely defined by Perry (1995). This means that other characteristics of SOS that are more difficult to observe or assess also may be applicable to drilospheres and should be explored. The shape and localization in soils of system spatial boundaries (for example, the limits among drilospheres and rhizospheres), the existence of discrete time boundaries at which different SOS interact (for example, critical stages during successional or invasive processes where earthworms trigger massive nutrient releases from organic reserves Bernier and Ponge 1994, McLean and Parkinson 1997), the exact nature of the hierarchical organization of SOS in soils, and the place of drilospheres in them all are research topics that...

Habitat

Unlike soil macrofauna (e.g., earthworms, termites, ants, some insect larvae), mesofauna generally do not have the ability to reshape the soil and, therefore, are forced to use existing pore spaces, cavities, or channels for locomotion within soil. Habitable pore space (voids of sufficient size and connectivity to support mesofauna) accounts for a small portion of total pore space (Hassink et al., 1993b). Microfaunal community composition becomes increasingly dominated by smaller animals as average pore volume decreases. Within the habitable pore space, microbial and mesofaunal activity is influenced by the balance between water and air. Maximum aerobic microbial activity occurs when 60 of the pore volume is filled with water (Linn and Doran, 1984). Saturation (waterlogging) and drought are detrimental to soil faunal communities because these conditions result in anaerobiosis or dehydration, respectively.

Arable Land

Intensive tilled arable farming systems occur worldwide, but are most prominent in industrialized countries in temperate regions. Intensive tilled agriculture bears little resemblance to highly complex unmanaged ecosystems. Arable soils are extremely disturbed by cultivation, fertilizers, and pesticides, all of which alter their biophysical composition (Anderson 2000). Plant communities of these conventionally managed, tilled agro-ecosystems are unnaturally simple. Intensive tillage farming negates the activity of many soil organisms, such as earthworms (Marinissen & de Ruiter 1993), ants (Decaens et al. 2002), and mycorrhizal fungi (Helgason et al. 1998), but some soil organisms continue to play an important role in the decomposition of crop residuals or organic manure, and are involved in the processes of nitrification and pesticide degradation (Anderson 2000). In intensive tilled agriculture, short rotations and the use of high-yielding crops can trigger development of...

Forests

Unmanaged forest ecosystems provide a diversity of ecosystem goods and services, and their ranks are moderate (food production) to strongly positive (e.g., fuel energy, recreation, carbon sequestration, and regulating trace gases) (Table 2.3). Biotic and abiotic processes have almost equal contributions to the rate or efficiency of the delivery of these goods and services. Plant roots play an important role in the regulation of the quality and quantity of water volume and erosion control, whereas soil bacteria are particularly important for the regulation of the trace gases in the atmosphere (Wang & Ineson 2003). Mycorrhizal fungi play an important role in the formation of organic matter in coniferous forests (Smith & Read 1997), whereas earthworms have some impact in deciduous forests (Lavelle et al. 1997). * earthworms *** roots organic matter formation * earthworms

Organic solid waste

Vermicomposting refers to the use of earthworms to augment or replace conventional composting. This process involves the physical breakdown (comminution) of organic matter by the worms and the action of intestinal microorganisms and the microorganisms that inhabit vermiculture substrates (Pizl and Novakova, 2003). The major attraction of vermicomposting is the improved market value of stabilized organic fertilizer produced, as compared with the soil conditioner fertilizer generated by standard composting. Several commercial vermicomposting facilities have been reported in North America and Asia (Sharma et al., 1997) along with a cautionary mention of issues of increasing production costs and low wholesale price margins while retail profits are high.

Vermistabilization

Vermistabilization (i.e., sludge stabilization and dewatering using earthworms) has been investigated in numerous locations and has been successfully tested full scale on a pilot basis (Donovan, 1981 Eastman et al., 2001). A potential cost advantage for the concept in wastewater treatment systems is the capability for stabilization and dewatering in one step as compared to thickening, digestion, conditioning, and dewatering in a conventional process. Vermistabilization has also been used successfully with dewatered sludges and solid wastes. The concept is feasible only for sludges that contain sufficient organic matter and nutrients to support the worm population.

Tolerating freezing

Number of animals can tolerate ice forming in their bodies, to varying degrees, including some insects and other arthropods, molluscs, nematodes, earthworms, frogs and turtles. Other groups of invertebrates, which inhabit soil or freshwater sites which periodically freeze, may be subject to inoculative freezing and need to be freezing tolerant to survive. Some tardigrades from Greenland and earthworms from Siberia have been reported to be freezing tolerant.

Life without water

Most animals and plants have only a limited ability to survive water loss. Humans may die if they lose 14 per cent of the water from their bodies. Some frogs can lose 50 per cent and some earthworms 83 per cent of their water and still recover. Some organisms, however, can lose more than 95 per cent, or even more than 99 per cent, of their water and enter into a state of anhydrobiosis (life without water) in which their metabolism comes, reversibly, to a standstill. There is a problem, however, in defining which organisms are capable of anhydrobiosis. Organisms show a whole range of abilities to survive water loss, ranging from losing just a little bit (as can humans) to losing almost all of it. At what point do we consider an organism to be anhydrobiotic

Although we may treat the claims of the cryogenecists with some scepticism, there are, remarkably, a number of organisms that have solved these problems and are able to survive the freezing of a substantial proportion of their water. These include a number of animals -some nematodes, molluscs, earthworms, insects, other arthropods and even frogs and turtles.
