Genetic analysis of Forbes' parakeet (Cyanoramphus forbesi)
The taxonomic status of Forbes' parakeet has remained unresolved for several decades. With the advent of modern molecular biological techniques, it has become possible to augment traditional taxonomic practices (i.e. those based on morphology) with DNA data analysis. The conservation status of Forbes' parakeet (presently listed by as "critically threatened") warrants urgent research into its ge...
متن کاملForaging Ecology of the Red-crowned Parakeet (cyanoramphus Novaezelandiae Novaezelandiae) and Yellow-crowned Parakeet (c. Auriceps Auriceps) on Little Barrier Island, Hauraki Gulf, New Zealand
New Zealand Journal of Ecology (1998) 22(2): 161-171 ©New Zealand Ecological Society Previous anecdotal observations suggested that the diets of red-crowned and yellow-crowned parakeets were similar. Both species have been observed feeding primarily on flowers, fruits, seeds, leaves and buds with invertebrates forming a relatively minor component of both species’ diet (Wilkinson and Wilkinson, ...
متن کاملComparative ecology of sympatric orange-fronted parakeets (Cyanoramphus malherbi) and yellow-crowned parakeets (C. auriceps), South Island, New Zealand
Sympatric orange-fronted (Cyanoramphus malherbi) and yellow-crowned parakeets (C. auriceps) were surveyed in a South Island beech (Nothofagus spp.) forest during the spring and summer of 1998/99. Habitat use, behaviour and diet were recorded for each parakeet identified. A single observer did all recording. Both species were seen most frequently in the upper-most 20% of the forest stratum. Oran...
متن کاملPrehistoric Mobility in Polynesia: MtDNA Variation in Rattus exulans from the Chatham and Kermadec Islands
Irwin (1992) has suggested that island accessibility in the Pacific, in terms oflatitudeand safety of return voyaging, for example, affects their degree of contact with otherislands and their role in Pacific prehistory. We present results of mtDNA variationin both ancient and modern populations of the Pacific Rat (Rattus exulans), an ani-mal that was transported by humans as the...
متن کاملThe effects of island forest restoration on open habitat specialists: the endangered weevil Hadramphus spinipennis Broun and its host-plant Aciphylla dieffenbachii Kirk
Human alteration of islands has made restoration a key part of conservation management. As islands are restored to their original state, species interactions change and some populations may be impacted. In this study we examine the coxella weevil, (Hadramphus spinipennis Broun) and its host-plant Dieffenbach's speargrass (Aciphylla dieffenbachii Kirk), which are both open habitat specialists wi...
