Self-Assemblage and Quorum in the Earthworm Eisenia fetida (Oligochaete, Lumbricidae)
Despite their ubiquity and ecological significance in temperate ecosystems, the behavioural ecology of earthworms is not well described. This study examines the mechanisms that govern aggregation behaviour specially the tendency of individuals to leave or join groups in the compost earthworm Eisenia fetida, a species with considerable economic importance, especially in waste management applicat...
متن کاملToxicity and bioaccumulation of ethofumesate enantiomers in earthworm Eisenia fetida.
Earthworms represent an important food source for many vertebrates and as a result, predators may encounter toxic effects via the food chain from consumption of contaminated worms. Therefore, including an assessment of xenobiotic to worms in risk assessment procedures is advisable. Here we studied the acute toxicity, bioaccumulation and elimination of ethofumesate enantiomers in earthworm, Eise...
متن کاملUniparental reproduction of Eisenia fetida and E. andrei (Oligochaeta: Lumbricidae): evidence of self- insemination
This study investigated the copulatory behaviour of the lumbricid earthworm Eisenia fetida (Savigny, 1826) in a natural population, and the uniparental reproduction of E. fetida and E. andrei Bouché 1972, two closely-related species. Sperm transfer occurred in 61 % of the matings observed, of which 88.2 % showed bi-directional sperm transfer, 9.8 % unidirectional sperm transfer and one earthwor...
متن کاملAnnotation of nerve cord transcriptome in earthworm Eisenia fetida
In annelid worms, the nerve cord serves as a crucial organ to control the sensory and behavioral physiology. The inadequate genome resource of earthworms has prioritized the comprehensive analysis of their transcriptome dataset to monitor the genes express in the nerve cord and predict their role in the neurotransmission and sensory perception of the species. The present study focuses on identi...
متن کاملGlycosylated trypsin-like proteases from earthworm Eisenia fetida.
Although groups of earthworm proteases have been found by several laboratories, it is still unclear how many of the isolated trypsin-like fibrinolytic enzymes are in glycosylated form. Here, eight glycosylated fibrinolytic proteases (EfP-0-1, EfP-0-2, EfP-I-1, EfP-I-2, EfP-II-1, EfP-II-2, EfP-III-1 and EfP-III-2) were isolated from an earthworm species (Eisenia fetida) through a stepwise-purifi...
