Folsomia minoraesp. n. and Folsomia australicasp. n. are described from New Zealand and Australia, respectively. Their possible affinity to two different groups of Cryptopygussensu stricto is discussed. Attention is paid to the variability of sensillary patterns of the genital segment in Cryptopygus: mainly, all s-chaetae are subequal, but in more advanced forms the dorsal triplet, lateral dupl...

The development of nanotechnology has accelerated the use silver nanoparticles (AgNPs) in household chemicals and accumulation Ag sewage treatment systems. application sludge products to soils raises concerns over safety function biogeochemical cycles soil belowground ecosystem. Here, we assess potential risk transfer under AgNPs exposure its effects on trophic nitrogen (N) through a animal foo...

We evaluated sequence diversity in the mitochondrial cytochrome-c oxidase I (COI; EC 1.9.3.1) gene as a tool for resolving differences among species of Arctic springtails. The Collembola examined in this analysis were collected from Igloolik, Cornwallis, and Somerset islands and included representatives from all major families found in the Arctic. Members of 13 genera and 19 species were examin...

Organic matter (OM) and pH may influence nanoparticle fate and effects in soil. This study investigated the influence of soil organic matter content and pH on the toxicity of ZnO-NP and ZnCl2 to Folsomia candida in four natural soils, having between 2.37% and 14.7% OM and [Formula: see text] levels between 5.0 and 6.8. Porewater Zn concentrations were much lower in ZnO-NP than in ZnCl2 spiked s...

Directional traps, both horizontal and vertical, were used to assess the behavioural impact of phenanthrene application on soil springtail communities. Avoidance was not detected. Rather, a vertical attraction of the dominant species, Folsomia manolachei, was demonstrated, as well as a decrease in horizontal movements of Lepidocyrtus lanuginosus, another important species mainly captured at the...

Nine new species of the genus Folsomia are described from Buryatia (Russia, East Siberia): F. biparis sp. nov., F. fumosa sp. nov., F. heterothorax sp. nov., F. maximovi sp. nov., F. pseudovtorovi sp. nov., F. sensivillosa sp. nov., F. uniparis sp. nov., F. uniramia sp. nov., and F. vitimica sp. nov. A complete list and a key to species recorded in the Buryatia are given, and their morphology, ...

A protocol was developed to detect bacteria inhabiting microarthropods by means of small-subunit rRNA-targeted fluorescence in situ hybridization and microscopy. The protocol is based on cryosections of whole specimens. In contrast to more commonly applied paraffin-embedding techniques, the protocol is quicker and reduces the number of manipulations which might damage the microscopic material. ...
