Niektóre zagadnienia z biologii i ekologii roztoczy z grupy Analgesoidea

The spreading paths of Analgesoidea are outlined. The exchange of Acarina among host species takes mostly place in the hatching period (passage from parents to feathering nestlings), and in birds leading a colonial system of life. The spreading rate is largely affected by the degree of Acarina specialization, their size and a ctivity. Having passed to new hosts Acarina take a constant localization characteristic of individual species. This distribution in biotopes may be disturbed by abiotic factors (cooling down, changes in humidity and light intensity) and biotic ones (associated with the host biology e. g, hatching period, change in plumage, migrations). Under the influence of these factors, the localization and population structure of the same Acarina species are liable to vary depending on the host.
