We investigated whether exposure to UV-B results in biochemical changes in leaf litter, affecting growth rates of earthworms feeding on this litter and cast chemistry. Seedlings of Betula pubescens L. were grown under zero and ambient UVB (at 52 °N) regimes under optimal conditions. Following three months exposure, plants were allowed to senesce and leaf litter was collected. Lumbricus terrestr...

Earthworms are nocturnal animals and have negative phototaxis, therefore the presence color of light thought to affect performance this Lumbricus rubellus earthworm. This study aims analyze effect different lights on performance. used acompletely randomized design (RAL), six treatments (red, orange, yellow, green, blue, purple, dark as a control) three replications with variables observed were ...

abstract soil salinity in huge parts of the world, especially in arid and semi-arid regions, is a factor limiting growth of plant and other organisms. earthworm can be considered as an indicator of soil quality in agroecosystems, because of a positive correlation between earthworm abundance and the productivity of cropped plants. the main objective of this study was to realize the interaction b...

Invasive species can affect native communities through multiple mechanisms, including habitat modification and trophic interactions. In North America, invasive jumping worms (Amynthas spp.) may alter microhabitats used by herpetofauna or serve as a novel prey resource for predators. We investigated effects of recently introduced Amynthas previously established Lumbricus spp. earthworms on leaf ...

We have determined the complete nucleotide (nt) sequence of the mitochondrial genome of an oligochaete annelid, the earthworm Lumbricus tarestris. This genome contains the 37 genes typical of metazoan mitochondrial DNA (mtDNA), including ATPase8, which is missing from some invertebrate mtDNAs. ATPase8 is not immediately upstream of ATPase6, a condition found previously only in the mtDNA of snai...
