Impacts of epigeic, anecic and endogeic earthworms on metal and metalloid mobility and availability.
The introduction of earthworms into soils contaminated with metals and metalloids has been suggested to aid restoration practices. Eisenia veneta (epigeic), Lumbricus terrestris (anecic) and Allolobophora chlorotica (endogeic) earthworms were cultivated in columns containing 900 g soil with 1130, 345, 113 and 131 mg kg(-1) of As, Cu, Pb and Zn, respectively, for up to 112 days, in parallel with...
متن کاملChanges in bacterial numbers and microbial activity of pig slurry during gut transit of epigeic and anecic earthworms.
In soils, organic matter decomposition and stabilization largely occur as a result of microbial activity, although when present, earthworms are important drivers of the processes through their interactions with microflora which begin during organic matter digestion by earthworms. Here, we studied the effects of gut transit on the number of bacteria and the microbial activity in pig slurry, usin...
متن کاملThe impact of soil organisms on soil functioning under neotropical pastures. A case study of a native anecic earthworm species
The description of main biological, ecological and functional attributes of a native earthworm species in a natural savanna and several introduced pastures from the Eastern Plains of Colombia was the main objective in this study. To achieve this a set of different experiments and explicit field work were designed and carried out at the Carimagua Research Station, 320 km east from Villavicencio ...
متن کاملInteractive effects of global warming and ‘global worming’ on the initial establishment of native and exotic herbaceous plant species
The spread of exotic earthworms (‘worming’) and rising temperatures are expected to alter the biological, chemical and physical properties of many ecosystems, yet little is known about their potential interactive effects. We performed a laboratory microcosm experiment to investigate the effects of earthworms (anecic, endogeic, epigeic, or all three together) and 4°C warming on soil water conten...
متن کاملImpact of copper application on soil metabolism, energy budget and formation of stable aggregates by anecic earthworm in tea plantations.
The preparation of daily energy budget of earth worm Lampito mauritii showed (i) decrease in consumption by about 66%, (ii) decrease of egestion 97%, (iii) decrease in growth by 80%, and (iv) enhancement in maintenance cost by about 31.5% on exposure to 8 ppm copper in comparison to zero level exposure. The stable aggregate formations also decreased by 67.6% at 8 ppm copper as compared to zero ...
