Morphological trends in the common brushtail possum, Trichosurus vulpecula, in New Zealand

Over 300 specimens of the Australian introduced common brushtail possum, taken from throughout its range in New Zealand, were measured. A north-south trend in skull size was found, which conforms with Bergmann’s rule. This trend probably evolved during less than 50 years (30-35 generations), and is not significantly different from the present Australian trend for skull size in this species. Males are slightly larger (1.8% in skull length) than females. (auths)
