Assortative mating in Ixodes scapularis Say, 1821 (Acari: Ixodidae)
Mate choice influences levels of inbreeding and genetic diversity in natural populations. Positive assortative mating (PAM), for instance, has been described in Ixodes ricinus L., but this behavior has yet to be investigated in the closely related Ixodes scapularis Say, 1821. By analyzing nine microsatellite loci of 30 females and 30 males removed in copula from hunter-harvested deer specimens at the Savannah River Site (South Carolina) during the hunting season of fall 2010, we found a weak but significant assortative pairing signature in a population that, otherwise, appeared genetically homogeneous. This indicated that in spite of a low average relative relatedness between members of the same pair, the difference between observed and all other possible male-female pairs was highly significant. The results suggested that our non-coding microsatellite loci were drafted by genes coding for PAM, through genetic hitchhiking. To explain our data, such genes would need to be homogeneously distributed in the genome and span from a few genes with major effects on PAM to many genes with moderate or weak effects on PAM.
期刊介绍:
Ticks and Tick-borne Diseases is an international, peer-reviewed scientific journal. It publishes original research papers, short communications, state-of-the-art mini-reviews, letters to the editor, clinical-case studies, announcements of pertinent international meetings, and editorials.
The journal covers a broad spectrum and brings together various disciplines, for example, zoology, microbiology, molecular biology, genetics, mathematical modelling, veterinary and human medicine. Multidisciplinary approaches and the use of conventional and novel methods/methodologies (in the field and in the laboratory) are crucial for deeper understanding of the natural processes and human behaviour/activities that result in human or animal diseases and in economic effects of ticks and tick-borne pathogens. Such understanding is essential for management of tick populations and tick-borne diseases in an effective and environmentally acceptable manner.
