The Vegetation of Subantarctic Campbell Island
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 majo...

متن کاملGrowth response of an invasive alien species to climate variations on subantarctic Campbell Island
Invasive alien species (IAS) are a recognised threat to biodiversity and ecosystem services. With increasing tourism and projected 21st century climate changes across the midto high-latitudes of the southern hemisphere, subantarctic islands are potentially highly vulnerable to IAS, but suffer from a dearth of baseline monitoring. Here we report tree-ring measurements from a lone exotic Sitka sp...

The aims of the fencing project were – 1. to assess the effects of sheep grazing on the native biota; 2. to remove the immediate threat to plant species and communities; 3. to help d...
متن کاملFoggo and Meurk: Jacquemart Island, Campbell Island Group
This paper describes the first visit to Jacquemart Island in the south of the subantarctic Campbell Island group. The island contrasts with the main island by the absence of introduced grazing mammals, rats (Rattus spp.) and feral cats (Felis catus), and in the dominance of palatable plant species. A survey of the main vegetation communities was made and bird species seen were recorded. Specime...
