The Overwinter Survival of three Earthworm Species in Mono- and Multispecific Assemblages

A recent survey in the main habitat types of Mt. Nimba, Guinea (upland prairie, Serengbara forest and piedmont savannah) resulted in recording of 13 earthworm species of which 9 are first reported after the original description and three, Dichogaster (Dichogaster) cornuta sp. n., Guineoscolex geminatus sp. n. and Guineoscolex ungulatus sp. n., proved to be new to science. On the basis of the new material collected Benhamia inaequalis f. nimbai Omodeo is redescribed and resurrected from synonymy of Guineoscolex inaequalis (Michaelsen) as an independent species Guineoscolex nimbai (Omodeo). With 17 original figures.

The general ecology of an undescribed indigenous earthworm species in the Megascolecidae, found in the organic horizons of Podzolic soils under mixed stands of Tsugaheterophylla, Abiesamabilis, Thujaplicata, and Pseudotsugamenziesii, is described. The earthworm is a member of the genus Arctiostrotus. Over a range of sites, population numbers of earthworms were correlated to rooting concentration in and immediately below the mor humus. By micromorphological examination, earthworm casts were found to account for up to 60% by volume of the constituent solids of the organic horizons. The abundance of both fine roots and fungal hyphae in the worm casts suggested high nutrient availability. Analysis of fresh faecal material showed a marked increase in most important nutrients (N, P, K, Mg, Fe, Na) relative to levels in noningested litter. Observations indicate that this earthworm species, whose population density may reach 200 m−2, has a major role in the decomposer subsystem of these ecosystems.

Preliminary Study

AbstractThe earthworm species belonging to the Lumbricidae family (Annelida, Oligochaeta) posses a complex oesophageal organ known as “calciferous gland” which secretes a concentrated suspension of calcium carbonate. Previous studies have demonstrated the non-crystalline structure of this calcareous fluid representing an interesting example of biomineralisation.
