History of the species range of ixodid ticks, vectors of pathogens with natural nidality (Acari, Ixodidae), as a prerequisite of their intraspecific biodiversity

Resumo

Morphological, taxonomic, and some ecological aspects of intraspecific biodiversity of five ixodid species transmitting pathogens with natural nidality, with extensive ranges of different types are examined. Causal relations of ixodid intraspecific biodiversity with the origin of the species ranges are considered.
