Extreme reversed sexual size dimorphism in the extinct New Zealand moa Dinornis

Article Abstract:

Research has been conducted on moa Dinornis species which dominated New Zealand biota until their extinction 500 years ago. The ancient mitochondrial DNA sequences have demonstrated that these species were indistinguishable within each island, but the use of sex-linked nuclear sequences from an extinct species has demonstrated that on each island the species' morphological forms represented just one species which differed in size according to habitat and sex.

The evolution of reproductive isolation through sexual conflict

Article Abstract:

Research has been conducted on populations with different sexual conflict levels. Results demonstrate that larger populations with more sexual conflict diverge to a greater degree than small populations with relaxed conflict.
