“…These results indicate, contrary to original predictions (Black et a!., 1988), that the amount of differentiation observed among local populations of Ac. albopictus in the United States is not a consequence of recent colonization but rather an attribute of the natural breeding structure of the species.…”

“…The same phenomenon was observed among local populations of Ae. albopictus in the United States (Black et aL, 1988). We attributed this variation in local U.S. populations to genetic drift associated with restricted gene flow among newly established populations.…”

“…However, the lack of population differentiation suggests that the recently burnt population is primarily a subset of the adjacent unburnt population. This view is supported by the presence of significantly fewer unique alleles in the burnt populations, which suggests that the fungal populations in the recently burnt sites are primarily derived from the unburnt area and have experienced a genetic bottleneck (Black et al, 1988). The few unique alleles that were detected in the burnt area, however, support the two additional genetic clusters detected by STRUCTURE.…”

The Fynbos Biome in the Core Cape Subregion of South Africa is prone to recurrent fires that can clear vast areas of vegetation. Between periods of fire, ophiostomatoid fungi colonize the fruiting structures of serotinous Protea species through arthropod-mediated dispersal. Using microsatellite markers, this study considered the process whereby a Protea-associated ophiostomatoid fungus, Knoxdaviesia proteae, recolonizes a burnt area. The genetic diversity, composition and structure of fungal populations from young P. repens plants in a recently burnt area were compared to populations from the adjacent, unburnt Protea population. The only difference between K. proteae populations from the two areas was found in the number of private alleles, which was significantly higher in the unburnt population. The population structure, although weak, indicated that most K. proteae 1 individuals from recently burnt areas originated from the unburnt population. However, individuals from unsampled source populations were also detected. This, together with the lack of isolation-by-distance across the landscape, suggested that long-distance dispersal is important for K. proteae to recolonize burnt areas. Similarly, the high level of gene flow and low differentiation observed between two distantly separated K. proteae populations also supported the existence of long-distance dispersal. The genetic cohesiveness of populations over long distances and the genetic diversity within populations could be attributed to frequent multiple fungal migration events mediated primarily by arthropods but, potentially, also by birds.

“…We undertook a nested spatial sampling of populations (Black et a!., 1988a(Black et a!., , b, 1989) which involved sampling a number of cities and several locations within some of those cities. This design may enable one to detect drift at the local level by the partitioning of variance in allele frequencies into two components, among locations within cities and among cities.…”

Texas 77054 U.S.A.The medically important mosquito, Aedes albopictus, has recently become established in several locations within the United States. A three-year survey of temporal variation in allele frequencies at ten enzymatic loci in 17 populations was undertaken to determine the extent and direction of change since the colonisation event. Significant, but nondirectional, changes were detected in allele frequencies at most of the loci in all populations. Some alleles detected at low frequencies in earlier samples were not found in subsequent samples. Variance of allele frequencies remained unchanged. In at least two locations, there was an increase in mean heterozygosity, perhaps because of gene flow. There was no significant change in the levels of genetic variation within and among populations. The results from this study indicate that the breeding structure of Ac. albopictus in the U.S. did not differ substantially from that in a native habitat, either soon after colonisation or after several generations in the new habitat. We suggest that a large founder population, gene flow and a rapid population expansion could explain the present breeding structure of Ac.albopictus.
