Some enchytraeid species of tropical, subtropical or Mediterranean origin can appear in artificial environments, e.g. green houses due to the worldwide commercial network. Since the used soil from green houses is often disposed outdoors, a question raised that these exotic enchytraeid species could survive under continental climate conditions. In this experiment two of the resettled green house...

Tourism has long been considered as a 'clean industry' with almost no negative effects on the environment. This study demonstrated, in two different coastal systems (Mediterranean and Baltic), that tourism related activities are particularly affecting the sandy beach meio- and nematofauna in the upper beach zone, the specific ecotone in which many meiofauna species from both the marine and the ...

Riparian vegetation along streams in the Atlantic Forest in Brazil contributes to the formation of a highly heterogeneous leaf litter in streambeds. To investigate the structure and composition of the aquatic invertebrate community during the process of leaf decomposition of two plant species present along the banks of the stream studied, 21 plastic mesh bags containing 2.5g (dry weight) of lea...

aims: textile industries are among the manufactures which produce the highly polluted waste water. the purpose of this research was to evaluate the effect of vermifiltration on cod and color removal from textile waste water. materials & methods: this experimental research was performed march to august 2014 in one of the textile factories of kashan region, iran. the glass cubic kits with- withou...

During the 1950s, Gordon E. Gates (affiliated at that time with Tall Timbers Research Station near Tallahassee, Florida, USA), initiated compilation of a catalogue scientific names Oligochaeta. transferred his account records to John W. Reynolds in 1972, who enlisted assistance David G. Cook, an aquatic biologist working Canada, complete this catalogue. The first volume catalogue, Nomenclatura ...

Underground community assemblies have not been studied well compared with aboveground communities, despite their importance for our understanding of whole ecosystems. To investigate underground community assembly over evolutionary timescales, we examined terrestrial earthworm communities (Oligochaeta: Haplotaxida) in conserved mountainous primary forests in Japan as a model system. We collected...

Biodiversity and structure of the benthic macrofauna communities were studied in the southeast the Caspian Sea (Golestan Province – Iran) during one year from October 2014 to September 2015. Seasonal samplings were done at 6 stations in 3 transects. Depth, temperature, salinity, pH, E.C., total organic matter and grain size were measured. More than 4,037 individuals belonging to five orders, Po...

Five lotic systems of Serra do Cipó, south-east Brazil, were investigated in order to assess the existing diversity of benthic macroinvertebrates, habitats-microhabitats, and the available trophic resources. For each river it was analysed the communities of benthic macroinvertebrates and the composition of some taxonomic groups (Plecoptera, Ephemeroptera, Trichoptera and Diptera Chironomidae): ...
