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 ...

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...

Notes on Ceramium (Rhodophyta: Ceramiales) from the Hawaiian Islands!

Ceramium is widely distributed and recorded from the coasts of the North Pacific Ocean. Thus, it is not surprising to find new species and new records of this genus among the numerous islands spread in this oceanic region. Extensive examination of material collected around O'ahu and other Hawaiian Islands has yielded two new records: Ceramium aduncum Nakamura (previously known from Japan), Cera...
