Influence of Interspecific Interference Competition on the Genetic Structure of Calopteryx splendens Populations
Understanding the effects of interspecific competition on genetic diversity will deepen our knowledge on species evolution. In the case of Calopteryx splendens and C. virgo, sympatric damselfly species, interspecific interference competition by C. virgo has remarkable effects on territoriality of C. splendens resulting in reproductive character displacement. Since territoriality is correlated with phenotype and mating success, we investigated the effects of interspecific interference competition on genetic diversity of C. splendens populations. Using amplified fragment length polymorphisms (AFLP), we determined the population genetic structure of 12 C. splendens populations and used the genetic diversity information to relate heterozygosity of C. splendens to abundance of C. virgo in sympatric populations. We found that heterozygosity of C. splendens males decreased with increasing abundance of C. virgo males. This result most likely reflects changes in effective population size due to interspecific interference competition and shows an effect on genetic structure in damselfly populations.
期刊介绍：
Annales Zoologici Fennici publishes mainly original research reports, but also in-depth reviews and commentaries on all aspects of animal ecology and evolution, and fields related to them. Our aim is to promote papers which focus on the interactions among various components in the past and present environments by using integrative and cross-disciplinary approaches. This may be achieved by employing tools from different fields of research, such as (but not restricted to):
ecology and paleoecology,
molecular ecology and phylogeography,
conservation biology, human-induced contemporary evolution and wildlife management,
animal behaviour and interactions (including recognition systems and mechanisms),
paleontology (except systematics and taxonomy) and evolution,
bioenergetics.
