Investigating soil mesofauna cryptic diversity: Current challenges and perspectives
Abstract Cryptic species lacking distinct morphological features are widespread among soil fauna, including such functionally significant groups as springtails, mites and enchytraeids. Their presence, diversity and biomass may impact ecosystem services provided by belowground ecosystems.

Cocoon viability and evidence for delayed hatching by the earthworm Lumbricus terrestris in a laboratory-based study. [PDF]
Clitellate Lumbricus terrestris, obtained from 5 commercial suppliers (A-E) and also field collected (F) - grassland in Preston, Lancashire, UK, were kept under controlled environmental conditions (15 °C and 24 h darkness) in a sterilised loam soil and ...

Basic Research Tools for Earthworm Ecology [PDF]
Earthworms are responsible for soil development, recycling organic matter and form a vital component within many food webs. For these and other reasons earthworms are worthy of investigation. Many technologically-enhanced approaches have been used within

Algunas consideraciones sobre los estudios actuales de la reproducción de los oligoquetos
El estado actual del problema de la reproducción entre los Oligochaeta se esboza aquí, con especial referencia al modo uniparental. Los métodos de exploración en esta esfera se amplían y se esboza tentativamente una clasificación eventual de las ...

Three genera of oligochaeta, i.e. Branchiura sowerbyi, Limnodrillus sp. and Lumbriculus sp. were fed on spores of Myxobolus artus before predated to juvenile of Cyprinus carpio. Spores of myxosporean were found on the fish, which get Limnodrillus.

The Role of Earthworms in Mediating Environmental Impacts on Mountain Ecosystem Functioning
ABSTRACT Aim Soils host a quarter of all terrestrial species, and the pivotal role played by earthworms in soil ecosystem functioning is thought to be paramount. Here, we aimed to quantify the causal influence of changing environments, especially climate, soil conditions, and vegetation type and structure, on earthworm diversity and the subsequent ...

Despite the importance of Oligochaeta to the dynamics of aquatic ecosystems and to studies of the biology of pollution, there is currently a dearth of information on this group's ecology in Brazil.

This study evaluates the opportunities and challenges of using DNA metabarcoding of river macroinvertebrates for routine ecological status assessment under the EU Water Framework Directive. By reanalysing data from rivers in north‐west Spain, it identifies key sources of false positives and negatives, compares bulk and eDNA sampling with traditional ...

Using oligochaeta assemblages as an indicator of environmental changes
We designed a field survey (the entire river length; not dammed: First and Second plateaus; dammed: Third Plateau) to test the hypothesis that the cascade of reservoirs promoted a reduction in species richness and changed the composition of Oligochaeta ...

Oligochaeta (Annelida: Clitellata) associated to aquatic macrophytes in Brazil
Oligochaeta are still characterized as a poorly studied group among the aquatic macroinvertebrates and few studies about their ecology were conducted in Brazil.
