A proposed order-level classification in Oligochaeta (Annelida, Clitellata) [PDF]
The purpose of our contribution is to propose a robust and practical order-level classification of the families of Oligochaeta, that is, non-leech Clitellata.

Um dos temas centrais em ecologia é a importância relativa dos processos locais e regionais na determinação da estrutura de comunidades, pois ambos os processos podem agir como filtros na composição das comunidades locais.

Earthworms (Haplotaxida: Lumbricina) are bioindicators of soil fertility. Agricultural systems applied to an agricultural area can affect the presence of earthworms there. This study aims to determine the density of earthworms in plantations owned by PT.

Vertical distribution of earthworms in grassland soils of the Colombian Llanos [PDF]
The vertical distribution of native earthworm species from natural and disturbed savannas in the Oxisols of the Colombian Llanos was assessed in a native savanna and in a 17-year-old grazed grass-legume pasture during a period of 17 months.

Influence of environmental factors on the benthic invertebrates community distribution in channels of a neotropical floodplain [PDF]
One of the central themes in ecology is the relative importance of local and regional processes for determining the communities’ structure, since both processes may behave as filters in the composition of local communities.

Implications of taxonomic modifications and alien species on biological water quality assessment as exemplified by the Belgian Biotic Index method [PDF]
In this paper, some important problems related to taxonomic resolution in water quality assessment by means of macroinvertebrates are discussed. Most quality indices based on macroinvertebrates only require identification up to genus or family level ...

Diversity of oligochaeta (Annelida) and Chironomidae (Diptera) of the argentinian Fluvial Litoral [PDF]
Oligochaetes and chironomids are considered by many authors as biological indicators of environmental conditions and are represented for a great species diversity in the benthic, pleuston and periphyton communities of different habitats.

Earthworms enhance soil structure, the decomposition of organic matter and the dissemination of beneficial soil organisms such as the entomopathogenic nematodes (EPNs). Nevertheless, the effects of earthworm feeding behavior or cutaneous excreta (CEx) on the performance of EPNs as biological control agents is poorly understood. We hypothesized that the
