Biology and Fertility of Soils, 2009 Low phosphorus (P) availability in Ferralsols of the Malagasy Highlands is a major limitation to crop growth. Direct seeding mulch-based cropping practices which were adopted in the region to improve and sustain soil fertility are known to favour earthworms’ presence.

On a collection of neotropical megadrili oligochaeta ii. Glossoscolecidae, lumbricidae
Studies on Neotropical Fauna and Environment, 1984From the Neotropical Region (Argentina, Paraguay, Brasil and Panama), 16 species and subspecies of terrestrial and amphibious Oligochaeta were studied. They are distributed onto 10 genera of 2 families as follows: Glossoscolecidae: Goiascolex vanzolinii, sp.n., Rhinodrilus duseni Michaelsen, 1918, G.

Invasion of Pontoscolex corethrurus (Glossoscolecidae, Oligochaeta) in landscapes of the Amazonian deforestation arc [PDF]
Applied Soil Ecology, 2010 Pontoscolex corethrurus (Glossoscolecidae, Oligochaeta) is an invasive endogeic earthworm that has colonized most land transformed by human activities in the humid tropics. When installed, populations can change soil physical properties, biogeochemical processes and microbial communities. The aim of this study was to determine whether P.

Characterization of possible symbionts in Onychochaeta borincana (Annelida: Glossoscolecidae)
European Journal of Soil Biology, 2007The presence of symbionts in the gut of Onychochaeta borincana has been suggested but they have never been characterized. The intestinal tissue of this species was examined using electron microscopy and microbiological and molecular biology techniques in order to identify the possible gut associated symbiont. Four gram-positive, endospore-forming and β-

New earthworm species of Righiodrilus (Clitellata, Glossoscolecidae) from eastern Amazonia
Zootaxa, 2017Three new species of the glossoscolecid earthworm genus Righiodrilus are described from material collected in northern Pará and Maranhão States, Brazil. Rhigiodrilus gurupi n. sp. is characterized by four pairs of post-testicular spermathecae in xiv–xvii. Rhigiodrilus viseuensis n. sp. is distinguished by tubercula pubertatis in xix–xxiii and clitellum

Biology and Fertility of Soils, 1997
The potential of Pontoscolex corethrurus to repair the physical degradation of a compacted Oxisol was studied. The Oxisol from Kingaroy, Queensland, Australia was uniformly packed to four treatments of different bulk densities (0.95, 1.15, 1.25, 1.35 Mg m–3) in pots of 0.24 m diameter and 0.22 m deep.

Pontoscolex(Oligochaeta, Glossoscolecidae), a new evaluation
Studies on Neotropical Fauna and Environment, 1984Meroscolex is interpreted as subgenus oiPontoscolex. The genus and its two subgenera are defined and the 13 species listed with their geographical distribution. A key to the species is presented and their phyletic relations and distribution discussed. Four new South‐American species are described: P. (P.) cuasi, P. (P.) nogueirai, P.

Abstract The pantropical, geophagous earthworm species Pontoscolex corethrurus (Muller) is common in lowland soils supporting sugarcanc in notheastern Queensland. In comparison with situations where harvest residues are burned, its populations are substantially increased under cultural treatments in which harvest residues are retained as a surface ...
