Title: Structure and floristic composition of the Heard Island "Pool Complex" Community

Description:

Abstract:

The stratigraphy, hydrology and vegetation of the Heard Island (sub-Antarctic; 53 deg. 05'S, 73 deg. 30'E) 'pool complex' bogs are described. Spatial variation in processes that might have contributed to their formation are discussed. This community occurs where drainage has been impeded, with Callitriche antarctia being the indicator species. Particular attention is paid to the interaction of the vegetation, pools and animals. Surface stratigraphy, peat depth, water depth and vegetation composition were measured along transect lines. Species over abundance data of 300 quadrats were classified using a two-way indicator of species analysis program and ordinated using detrended correspondance analysis. The major factors determining vegetation composition were found to be peat depth, surface topography, and the degree and type of animal disturbance. Similarities between the pool complexes on Heard Island and bogs back in Tasmania, and northern hemisphere temperate and boreal zones appear to diminish as the density of the animals occupying this habitat increases.

Attribute_Accuracy_Report:

At each of the nine study sites transects were subjectively located along a compass bearing that coincided with the long section of the pool complex. At most sites a second transect was located at right angles to the first. This method allowed extensive sampling of variation within and between pool complexes. Both transects extended to the margins of the pools. Along the set transect-lines, surface straigraphy, peat depths, water depths and vegetation composition were determined. The percentage cover of each species, in 1 metre squared quadrats, at 10 metre intervals along the transect-lines, was recorded. However, in transect 1 (at Red Island), species were continuously recorded along a line transect of 27.5 metres. Vascular plants were differentiated at the species level but bryophytes and lichen were each treated collectively.
