Poisoning Rats on Stewart Island
Poison was used at remote anchorages of southern Stewart Island in spring and summer of 1984/85 to reduce the likelihood of ship rats (Rattus rattus), Norway rats (R. norvegicus) and kiore (R. exulans) boarding fishing boats heading for the Snares Islands. Poison baits were removed at successively slower rates, probably because poisoning had reduced rat numbers. The effectiveness of poisoning w...
متن کاملAnagenetic evolution in island plants
The origin of new species on oceanic islands has been discussed on many occasions (Carlquist, 1974; Grant, 1996). The most commonly described process is speciation associated with adaptive radiation (Stuessy & Ono, 1998; Schluter, 2000), in which from a single introduction several lines of speciation occur, each driven by selection within markedly different ecological zones. Morphological diver...

متن کاملHabitat use by three rat species (Rattus spp.) on Stewart Island/ Rakiura, New Zealand
The relative abundance of ship rats (Rattus rattus), Norway rats (R. norvegicus), and Pacific rats (R. exulans), was measured in four vegetation types on Stewart Island/Rakiura, over six consecutive seasons. Ship rats were found in all four vegetation types and dominated in podocarp-broadleaf forest and riparian shrubland. Norway rats were most common in subalpine shrubland and Pacific rats dom...
متن کاملStrong Phylogeographic Structure in a Sedentary Seabird, the Stewart Island Shag (Leucocarbo chalconotus)
New Zealand's endemic Stewart Island Shag (Leucocarbo chalconotus) comprises two regional groups (Otago and Foveaux Strait) that show consistent differentiation in relative frequencies of pied versus dark-bronze morphotypes, the extent of facial carunculation, body size and breeding time. We used modern and ancient DNA (mitochondrial DNA control region one), and morphometric approaches to inves...
