Soil macrofauna: Study problems and perspectives
Soil Biology and Biochemistry, 2021Abstract The soil macrofauna, including animals between 1–2 mm and 20–30 mm in size, uses soil differently from the mesofauna, which lives in cavities, or microfauna that inhabits water films. In some ecosystems, the macrofauna accounts for most of the total soil animal biomass and substantially contributes to soil food-web functioning. Additionally,

Abstract The aims of this study were to analyze the composition and diversity characteristics of soil macrofauna community and the response of soil macrofauna to soil properties in an alpine river wetland of the Lhasa River basin. Soil macrofauna were investigated in nine wetland habitats of the Lhasa River basin in September 2009 and 2010.

Soil macrofauna and nitrogen on a sub-Antarctic island
Oecologia, 1992The densities, diets and habitat preferences of the soil macrofaunal species on sub-Antarctic Marion Island (47°S, 38°E) are described. Their role in N cycling on the island is assessed, using a mire-grassland community as an example. Primary production on the island is high and this leads to a substantial annual requirement of nutrients by the ...

Soil macrofauna research in ecosystems in Uganda [PDF]
African Journal of Ecology, 2007 AbstractSoil is a living entity, comprising an inseparable mixture of solid, liquid and gaseous phases, and diverse fauna and flora, the below ground biodiversity. The macrofauna consists of animals longer than 4 mm or wider than 2 mm, which are easily located by the naked eye and include arthropods, molluscs and earthworms.

Soil Fungi and Macrofauna in the Neotropics
2007Decomposition is a critical ecosystem function that decomposes dead organic materials, removes wastes, recycles nutrients and renews soil fertility. In natural ecosystems most nitrogen (N) and phosphorous (P) required for plant growth are supplied through the decomposition of detritus, relying therefore on the activities of soil microbes and macrofauna.

Applied Soil Ecology, 2011
Maintenance of soil organic matter through integrated soil fertility management is important for soil quality and agricultural productivity, and for the persistence of soil faunal diversity and biomass. Little is known about the interactive effects of soil fertility management and soil macrofauna diversity on soil aggregation and SOM dynamics in ...

Abstract Australian farmers are searching for reliable, easily measured indicators of soil health to monitor sustainability of their enterprises. Over the past 5 years earthworms have been promoted as indicators of soil health by some researchers. Others have been reluctant to accept soil macrofauna in general as soil health indicators.

Impact of Pollution Caused by Uranium Production on Soil Macrofauna
Environmental Monitoring and Assessment, 2003Thirty years of mining and milling activities of the Priargunsky Mining-Chemical Production Company (South-Eastern Siberia, Russia) have resulted in an enrichment of uranium in adjacent steppe soils by a factor of up to 600. A number of attendant pollutants (thorium, arsenic and heavy metals) also have high concentrations in the soil.

Mesofauna and Macrofauna in Soil and Litter of Mixed Plantations
2020The cultivation of leguminous nitrogen-fixing tree species improves soil chemical properties, especially with regard to N, and has been identified to be ecologically and economically interesting in intercropped systems with Eucalyptus spp., although the effect of these mixed plantations on soil and litter invertebrates still is poorly understood.

Abstract Soils participate in the provision of numerous ecosystem services of great importance for the maintenance of ecosystems and human societies. Physical and chemical soils properties sustain supporting ecosystem services like plant production and the infiltration and provision of clean water.
