A new feather mites species, Proctophyllodes valchukae sp. n., is described from the Long-tailed Tit, Aegithalos caudatus (Linnaeus, 1758) (Passeriformes: Aegithalidae), captured in the Primoriye (Russian Far East). The new species belongs to the tricetratus species group and is most closely related to P. stachyris Atyeo et Braasch, 1966. For the first time for feather mites the standard morpho...

The paper presents an extention of analytical reviews concerning the dormant stages in life cycles of representatives of the complex group of chelicerate arthropods, named the Acari or Acarina. The previous reviews were devoted to the comparative and evolutionary aspects of dormant stages distribution in life cycles of mites and ticks in comparison to mandibulate arthropods — insects and crusta...

Ecosystem engineers affect other species by changing physical environments. Such changes may influence movement of organisms, particularly belowground where soil permeability can restrict dispersal. We investigated whether earthworms, iconic ecosystem engineers, influence microarthropod movement. Our experiment tested whether movement is affected by tunnels (i.e., burrows), earthworm excreta (m...
