Species that thrive in compost will not survive the harsher conditions of paddock soils, which dry near the surface. There are many, many species of earthworm. Here we tested whether and to what extent the epigeic earthworms Eisenia andrei, Eisenia fetida and Perionyx excavatus, widely used in vermicomposting, are capable of altering the microbiological properties of fresh organic matter in the short-term. The most diverse families of earthworm species in India are Megascolecidae comprises 153 species (119 native) of 15 genera; Octochaetidae with 130 species (129 native) of 29 genera and Moniligastridae with 83 species (all native) of 3 genera. New research, published this week in BMC Evolutionary Biology, provides the most comprehensive evolutionary history yet of the origins of the 6000+ species of earthworm.

Endogeic earthworms (c) … The humble earthworm has been ranked above dinosaurs, bacteria and even mankind in a new league table of the most successful 100 species on Earth. Because of their narrow ecological plasticity to soil edaphic factors, members of the largest native genus Eutyphoeus can be considered as “stenoecious.” One such species is Eisenia fetida (brandling or tiger worm), recognisable by its stripy appearance, another is Dendrobaena veneta. This aligns well with EGrowth, a global database collating information from 1073 growth curves encompassing some 51 earthworm species, which revealed that 22.7% of data was derived from the earthworm E. fetida, 8% from E. andrei and 2.1% from Dendrobaena veneta (Mathieu, 2018).
