Heritability of dispersal rate and other life history traits in the Glanville fritillary butterfly

Article Abstract:

Parent-offspring regression was used to estimate heritabilities of dispersal rate and other life history traits in the Glanville fritillary butterfly under natural conditions in a large outdoor population cage. Results showed that dispersal rate is heritable but only from the mother to her female offspring.

Genetic evidence for a family-based Scandinavian settlement of Shetland and Orkney during the Viking periods

Article Abstract:

The invasion of the Scandinavian invaders had an enduring cultural impact on North Atlantic populations, but the extent of the genetic legacy is not clear. An extensive survey of Y-chromosomal and mitochondrial DNA variation in North Atlantic region is made to explore this idea.

Quantitative genetic variation in an island population of the speckled wood butterfly (Pararge aegeria)

Article Abstract:

Quantitative genetic variation for the Speckled Wood butterfly Pararge aegeria is analysed on the island of Madeira about 120 generations after first colonization. Observations reveal reduction of additive genetic variance since colonization.
