Many species of gadfly petrel (genus Pterodroma) are threatened or endangered, including, in New Zealand, the Chatham petrel (Pterodroma axillaris), and Pycroft's petrel (P. pycrofti). Conservation actions for these species include the establishment of ne ...

This project was initiated in May 1999 with the aim of determining optimum rearing conditions to breed Lyperobius huttoni in captivity. The programme has been relatively unsuccessful with only a single individual reared in captivity during 2001. However, ...

Weta motels were used to non-destructively sample cavity-dwelling species to provide a snapshot of forest diversity and health. Another non-destructive sampling method uses wooden discs as facsimiles for natural fallen logs to sample large soil-dwelling i ...

Six stands located on different land forms in mixed old-growth Nothofagus forests in the Matiri Valley (northwest of South Island, New Zealand) were sampled to examine the effects of two recent large earthquakes on tree establishment and tree-ring growth, ...

We examined whether the growth dynamics of two species can explain their coexistence. In particular, we examined New Zealand forests dominated by Nothofagus fusca and N. menziesii to determine whether both species can reach the canopy in tree-fall gaps. S ...
