Abstract:
A preliminary survey on earthworm species from north Karnataka region, Gulbarga district, Karnataka state, India, has been conducted from January 2012 to December 2013. Survey was conducted in three regions of Gulbarga district i.e. Afzalpur, Chittapur, and Sedam taluk. Six species of earthworms were identified belonging to four families namely lumbricidae, Octochaetidae, Megascolecidae and Eudrilidae. Eisenia fetida belonging to family lumbricidae, Dichogaster bolaui belong to family Octochaetidae, Polypheretima elongate, Perionyx sansibaricus and Perionyx excavates belong to family Megascolecidae and Eudrilus eugeniae belonging to family Eudrilidae. Among the species, Eudrilus eugeniae does not occur naturally and are produced from external sources for vermicomposting units.

Abstract:
The taxonomy of earthworms in Nigeria has been mainly on the family Eudrilidae. The present work describes four new earthworm genera belonging to earthworm families other than the Eudrilidae. Earthworm samples were collected using the digging and hand-sorting method. The earthworms are preserved in formoacetic alcohol. The four taxa described here include Imekodrilus hexagastricus (family Moniligastridae), Adodrilus stephana (family Megascolecidae), Parnematogenia eyinwaensis and Ekitidrilus alabataensis(family Ocnerodrilidae). Imekodrilus hexagastricus from Imeko, Ogun State has six gizzards, characteristic of members of the family Moniligastridae. The genus Adodrilus is compared with 3 earthworm genera, Diporochaeta, Plutellus and Perionyx. The genus and species lacks gizzards. The calciferous glands (a pair) are present, with left and right united in segment X. Four individuals of P. eyinwaensis were collected from Eyinwa, Odogbolu Local Government Area of OgunState. The species is here described as having same position and number of calciferous glands, testes and male pores as the genus Nematogenia. Also described here is E. alabataensis, which was collected from both Ado-Ekiti and Alabata, south west Nigeria. These four genera and species are here presented as new taxa of earthworms from southwest Nigeria.ª¤?

Abstract:
The population dynamics of the exotic earthworm Hyperiodrilus africanus was investigated in a secondary forest of the Natural Reserve of Lamto (Ivory Coast) over a period of 19 mo. The objectives were to assess seasonal abundance patterns and to determine the adaptive strategies of this species. Each month, 10 soil samples of 100×100×40 cm and 20 monolith samples of 25×25×30 cm were randomly excavated in a plot of 50×95 m and earthworms were extracted by both hand-sorting and wash-sieving methods. The results show significant inter-annual and seasonal fluctuations in population size. Three factors are likely to control population dynamics: (1) rainfall, (2) soil water content and (3) seasonality. The dry season appears to be the most important environmental factor that regulates population abundance when predation, density-dependent regulation and competition phenomena are ignored. Hyperiodrilus africanus exhibited an r strategy, suggesting a high ability to recover populations affected by drought.

Abstract:
Hyperiodrilus africanus est un ver de terre tres repandu en afrique de l'ouest (benin, togo, nigeria, cote d'ivoire) et en afrique centrale (congo, republique democratique du congo). La distribution regionale et l'adaptation aux milieux perturbes (agro-ecosystemes) font de ce ver, une espece potentiellement utilisable dans les experimentations de maintien ou d'amelioration de la fertilite des sols dans les systemes de cultures a faibles intrants. Il apparait alors necessaire d'etudier la biologie et l'ecologie de cette espece. Dans une parcelle de savane mis en defend de la reserve de lamto (cote d'ivoire) ou l'espece est apparue dans les annees 1980, des etudes de laboratoire et de terrain ont ete menees dans le but de comprendre le fonctionnement de ses populations. H. Africanus est un epi-endoge polyhumique de taille moyenne dont l'activite et les fluctuations d'abondance des individus sont calquees sur le rythme saisonnier : une phase de croissance en saison humide suivie d'une phase de decroissance et de quiescence (strategie efficace de survie) en periode seche. La duree de vie maximale d'un individu est estimee en moyenne a 8 mois. Grace a sa forte capacite d'expansion (importante fecondite : 30 cocons adulte - 1 an - 1 ; taux net de reproduction : 2. 24 individus ; temps de generation : 3 mois ; parthenogenese), h. Africanus est devenu en l'espace de deux decennies une espece clee du peuplement de vers de terre de la savane protegee du feu. La grande saison seche est le principal facteur qui regule l'effectif des populations. En milieu naturel, les populations sont a l'equilibre car leur taux de croissance est voisin de 1. Le devenir d'une population depend de la survie des immatures et adultes. Le phenomene d'extinction peut survenir a long terme a la suite d'une variabilite de l'environnement. Grace a son effet decompactant sur le sol, h. Africanus represente avec m. Anomala (fonction compactante), les principaux groupes fonctionnels a structure spatiale opposee.
