cluster analysis

The vegetation of Campbell Island and its offshore islets was sampled quantitatively at 140 sites. Data from the 134 sites with more than one vascular plant species were subjected to multivariate analysis. Out of a total of 140 indigenous and widespread adventive species known from the island group, 124 vascular species were recorded; 85 non-vascular cryptogams or species aggregates play a major role in the vegetation. Up to 19 factors of the physical environment were recorded or derived for each site.

Satellite transmitters (PTTs) were attached to four kereru (New Zealand pigeon, Hemiphaga novaeseelandiae) in Invercargill, Southland, New Zealand, during 2005–06. The transmitters were used to monitor the birds’ locations, movements and home ranges. Attachment of the transmitters affected the behaviour and body condition of one of the kereru; no other negative effects, such as skin abrasion, were noticed.
