The spatial pattern of Enchytraeidae (Oligochaeta)
Oecologia, 1985Spatial pattern of enchytraeids (Oligochaeta: Enchytraeidae) was studied in an experimental plot in an apple orchard near Bavorov, South Bohemia, Czechoslovakia. A total of 450 soil cores were taken in 1982, all individuals were determined (juveniles to genus, mature individuals to species) and counted. In total, 17 species of 4 genera were found. Both

Molecular phylogeny of Enchytraeidae (Annelida, Clitellata)
Molecular Phylogenetics and Evolution, 2010A multigene data set (12S, 16S, and COI mitochondrial DNA; 18S and 28S nuclear DNA) was analyzed by Bayesian inference to estimate the phylogeny of a sample of the clitellate family Enchytraeidae (86 species representing 14 nominal genera). Monophyly, as well as a basal dichotomy, of the family Enchytraeidae obtained maximum support, with one clade ...

Phylogeny and origins of Enchytraeidae
Hydrobiologia, 1989Phylogenetic analyses of Achaetinae (Enchytraeidae: Oligochaeta) and other bisetate enchytraeids indicate that the achaetines include the earliest species of Enchytraeidae but that Achaetinae is not monophyletic. The earliest species of bisetate enchytraeid now extant are restricted to South America, Africa, and India.

Asexual Reproduction in the Enchytraeidae (Olig.) [PDF]
Nature, 1959 ASEXUAL 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 ...

Pseudofertilization in the Genus Lumbricillus (Enchytraeidae)
Nature, 1958NATURAL populations of the common enchytraeid worm Lumbricillus lineatus Mull., occurring in decaying seaweed, contain diploid (2n= 26) and triploid (3n = 39) individuals. The Enchytraeidae are normally hermaphrodite but the triploid form of L. lineatus reproduces parthenogenetically and is distinguishable from the diploid type by the absence of ...

Methods for collecting enchytraeidae during expeditions
Soil Biology and Biochemistry, 1992Abstract There have been few faunistic studies of Enchytraeidae outside Europe and North America. This is partly due to inadequate taxonomic literature and difficulties associated with the examination of fixed material but also because methods for the collection of these worms, especially soil species, are not well known. Methods are described which

Toxicity and bioaccumulation of phenanthrene inEnchytraeus albidus(Oligochaeta: Enchytraeidae)
Environmental Toxicology and Chemistry, 2011AbstractPolycyclic aromatic compounds, such as phenanthrene (PHE), tend to accumulate in the soil compartment, where they may be retained for many years because of their persistency and hydrophobicity. The toxicity and bioaccumulation of these chemicals in soil biota and potential biomagnification along the food chain is an issue of concern.

Preliminary report on the Enchytraeidae (Oligochaeta) of West Florida [PDF]
Hydrobiologia, 1989 A wide range of habitats, both terrestrial and marine littoral, were sampled in an area between Pensacola and Tallahassee. Enchytraeids were present in all moist or wet soils and in marine habitats enriched by organic matter but were absent or rare in very dry soils, saturated or flooded substrates and clean intertidal sand.

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 ...
