Growth form and population genetic structure of Azorella selago on sub-Antarctic Marion Island
(Cambridge Journals, 2008)
Seven community complexes have been described across sub-Antarctic Marion Island, amongst these fellfield that comprise low plant cover dominated by Azorella selago Hook. f. Azorella is considered a keystone species since ...
Contrasting nurse plants and nurse rocks: The spatial distribution of seedlings of two sub-Antarctic species
Positive plant interactions, such as those associated with nurse plants, have been suggested to dominate over negative interactions in environments with high abiotic stress. Here we demonstrate that the sub- Antarctic ...
Fine scale variability in soil frost dynamics surrounding cushions of the dominant vascular plant species (Azorella Selago) on Sub-Antarctic Marion Island
(Swedish Society for Anthropology and Geography, 2009)
Through changing soil thermal regimes, soil moisture and affecting weathering and erosion processes plants can have an important effect on the physical properties and structure of soils. Such physical soil changes can in ...
Spatial variation in structural damage to a keystone plant species in the sub-Antarctic: interactions between Azorella selago and invasive house mice
(Antarctic Science Ltd, 2009)
On Southern Ocean islands the effects of the house mouse on plants are not well understood. In particular, its influence at the landscape scale has largely been overlooked. To address this issue, we systematically mapped ...
