Mitochondrial DNA signatures of restricted gene flow within divergent lineages of an atyid shrimp (Paratya australiensis)

Article Abstract:

The spatial genetic structure within three mitochondrial lineages of the atyid shrimp, Paratya australiensis, occurring in upland streams of two major catchments within the Sydney Water Supply Catchments, New South Wales, and Australia is measured. It is suggested that restricted dispersal and gene flow among upland populations of P. australiensis is linked to dramatic architectural structuring within and among mountain streams.

The head and body lice of humans are genetically distinct (Insecta: Phthiraptera, Pediculidae): Evidence from double infestations

Article Abstract:

Microsatellite DNA is used to study 11 double infestations, that is, hosts infested with head lice and body lice simultaneously. The results indicate that head and body lice are separate species, and lice had migrated from head to head, and from body to body, but not between head and bodies.

Transmission ratio distortion in the human body louse, Pediculus humanus (Insecta: Phthiraptera)

Article Abstract:

Inheritance at three microsatellite loci in eight F1 and two F2 families of the body louse of humans, Pediculus humanus is studied. Results are preliminary evidence for transmission ratio distortion of paternal alleles in the body louse, P. humanus.
