Genetic structure of Proclossiana eunomia popuations at the regional scale (Lepidopter, Nymphalidae)
Article Abstract:
Genetic structure of Proclossiana eunomia (Lepidopter, Nymphalidae) populations in northern France and southern Belgium has been studied at the regional scale using allozyme electrophoresis. Autocorrelation analysis showed that allele frequencies are positively correlated for populations as far as 13 km apart and that the genetic neighborhood of individuals is in the 0.9 km range. Patches isolated by 2km+ of mature forests were genetically distinct from the neighboring populations. The highest differentiation is seen between populations of the same subregion. The Ardennes region overall, however, is not genetically broken up into subregions, likely because connectivity of the network of suitable habitats has significantly weakened only since the 1950s.

Lack of genetic differentiation among widely spaced subpopulations of a butterfly with home range behaviour
Article Abstract:
Genetic differentiation has been studied in seven widely spaced subpopulations of Haliconius charithonia, a butterfly having home range behavior. Little genetic variation was seen, especially relative to populations of the same and related species from mainland South America. It seems the dispersal ability of Heliconius butterflies is underestimated, but it is not likely that greater dispersal ability by itself could account for lack of genetic differentiation seen in subpopulations almost 80 km apart. Absence of differentiation is best accounted for by current or quite recent gene flow following a steppingstone model. Extensive habitat fragmentation around Miami, FL, seems not to limit gene flow in urban subpopulations of the butterflies. Cellulose acetate electrophoresis was used in the study.

Population genetic structure in a Robertsonian race of house mice: evidence from microsatellite polymorphism
Article Abstract:
Evidence from microsatellite polymorphism on the population genetic structure in a Robertsonian fusion (Rb) race of house mouse, Mus musculus domesticus, in central Belgium is discussed. No association with karyotype or geographical distance was shown over 8-60 km and low values of effective size were seen in a successively sampled population. Combined effects of genetic drift and extinction-recolonization with lack of inbreeding may promote Rb polymorphism in the mice.
