Three new Fridericia species (Oligochaeta, Enchytraeidae) from Transylvania, Romania
Zootaxa, 2015We give descriptions of three new Fridericia species (Enchytraeidae, Oligochaeta) from Transylvania, Romania. Fridericia transylvanica sp. n. is a large-sized worm with a maximum of 4 chaetae per bundle. The spermathecae are separate entally and have two sac-like diverticula bent distad with the ampulla forming a common U-shaped sperm-containing ...

Specific criteria in Grania (Oligochaeta, Enchytraeidae)
Hydrobiologia, 1984The structure of the penial bulb and male efferent duct system of Grania species may be used in addition to setal pattern and spermathecal shape to distinguish species. Six penial bulb types are distinguished: (1) a simple, small, glandular bulb surrounding the male pore; (2) a small, glandular bulb, with a large, associated, dorso-medial gland mass ...

Efflux pump activity in Enchytraeidae
2019Enchytraeids are ecologically relevant soil organisms, which play an important role in organic matter decomposition and soil bioturbation. They live in close contact with the pore water fraction of soil which makes them vulnerable to xenobiotics exposure.

Segment formation of Enchytraeus japonensis (Oligochaeta: Enchytraeidae)
Pedobiologia, 2003Enchytraeus japonensis reproduces both sexually and asexually (by fragmentation). Following fragmentation, segment formation takes place along with organ regeneration and stem cells are supposed to play a crucial role. Thymidine analogue bromodeoxyuridine (BrdU) is widely used as a marker of cell proliferation, since it is incorporated into newly ...

Asexual Reproduction in the Enchytraeidae (Olig.)
Nature, 1959ASEXUAL reproduction has only recently been recorded in the Enchytraeidae 1. This inability of Enchytraeidae to reproduce asexually is in sharp contrast with the situation within the families of Naididae and Aelosomatidae. We have, however, found asexual reproduction to occur in three species of Enchytraeidae among the 78 Danish species hitherto ...

Dynamics of Enchytraeidae Populations on Hardangervidda
1975The dynamics of two Enchytraeidae populations at Stigstuv were studied over a period of 3 years. The sites selected were the dry and wet meadow (Sonesson et al., 1975). For various reasons, the group had to be mostly treated collectively during this investigation.
