Burrowing seabirds affect forest regeneration, Rangatira Island, Chatham Islands, New Zealand

The forests of Rangatira Island (218 ha) in the Chatham Islands are a critical breeding site for a number of rare and threatened forest bird species, but are also home to more than three million seabirds, which could significantly affect forest regeneration processes. We surveyed the forests of Rangatira Island by establishing 40 permanent forest plots, estimated seabird density through burrow ...

Prehistoric 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...

Human-mediated extirpation of the unique Chatham Islands sea lion and implications for the conservation management of remaining New Zealand sea lion populations.

While terrestrial megafaunal extinctions have been well characterized worldwide, our understanding of declines in marine megafauna remains limited. Here, we use ancient DNA analyses of prehistoric (<1450-1650 AD) sea lion specimens from New Zealand's isolated Chatham Islands to assess the demographic impacts of human settlement. These data suggest there was a large population of sea lions, uniq...
