An alarming proportion of Australias unique plant biodiversity is under siege from a variety of environmental threats. Options for in situ conservation are becoming increasingly compromised as encroaching land use, climate change and introduced diseases are highly likely to erode sanctuaries...
The function of orbicules has been a matter of speculation for a long time and until now no satisfactory answer has been put forward. We propose two hypotheses that could contribute to the elucidation of their function: (1) that anemophilous and buzz pollination species have microechinate...
Melaleuca deanei F.Muell. is a rare, serotinous shrub with a naturally restricted distribution centred over the sandstone ridges around Sydney. Sexual reproduction and seedling recruitment occur rarely, and plants appear to spread and persist largely by clonal root suckering. A potentially...
Ecological theory predicts that the success of exotic plants in new environments depends on a combination of ecological attributes. Requirements for germination and seedling traits are the main components in the regenerative niche, and largely determine the success of exotic species in a new...
The value of distinguishing between plant species regarded as native and alien has special relevance in the island continent of Australia, where European settlement was a springboard for human-assisted plant dispersal. The year of European settlement is proposed here as providing a distinction...
Edaphic gradients can explain plant species distribution at a local scale in the neotropics and elsewhere, but few studies have evaluated the individual responses of species to such gradients. We collected data on species and soils in open savannic and forest formations (totalling five habitats...
