To determine the effects of competition and divergence time on morphological dissimilarity and geographical range overlap between dasyurid species at both regional and local scales. Our hypothesis is that speciation in this group has been largely allopatric at regional scale, but involved morphological divergence at local scale through sympatric character displacement.

达修里德有袋动物的物种形成地理

为了确定竞争和发散时间对达苏里德物种在区域和地方尺度上形态差异和地理范围重叠的影响。我们的假设是，该群体的物种形成在区域范围内基本上是异特异的，但通过同胞性格位移而在局部范围内涉及形态差异。
