Sex ratio and Wolbachia infection in the ant Formica exsecta

Article Abstract:

Wolbachia infection in the ant Formica exsecta and sex ratio are discussed. PCR assay was used to determine prevalence of Wolbachia in workers from colonies specializing in male and female production in a Swiss and a Finnish population. In neither population, was a significant association in the predicted direction between the prevalence of Wolbachia and colony sex ratio. Where more workers were infected, more females were not found. Another study population was in Switzerland and had colonies that typically have numerous queens. No association between relatedness asymmetry and sex allocation was seen in the Swiss population.

Contrasting patterns of genetic variation in the two sympatric geckos Gekko tawaensis and G. japonicus (Reptilia: Squamata) from western Japan, as revealed by allozyme analyses

Article Abstract:

Research has been conducted on congeneric sympatric geckos from western Japan, Gekko tawaensis and G. japonicus. The authors have investigated the allozyme variation in these geckos, and describe species' different genetic patterns revealed by allozyme analyses.
