American Journal of Botany, EarlyView.Abstract Premise In edaphic old‐growth grasslands, the low nutrient content of the soil restricts plant species establishment. Additionally, fire remains an important factor in shaping vegetation structure and belowground biomass investment in old‐growth grasslands, such as the campos rupestres.

American Journal of Botany, EarlyView.Abstract Premise Understanding how disturbance regimes influence temperate grasslands is crucial for adapting management strategies to climate change, particularly in response to the loss of winters. The interaction between disturbance and climate can alter winter soil insulation and potentially the plant community.

American Journal of Botany, EarlyView.Abstract Premise Rainforests are usually too wet to burn, acting as natural barriers to fire spread and as refuges for biodiversity. However, climate change is increasing the risk of fire incursion into rainforests. Our capacity to manage these impacts is hindered by limited research on rainforest flammability.

Toward a functional understanding of novel fire regimes in tropical forests
American Journal of Botany, EarlyView.Abstract Climate change and land‐use alterations are driving forest fires to unprecedented frequencies and intensities worldwide. Even wet tropical forests—historically rarely subjected to fire—are increasingly experiencing fire disturbances. The impact of wildfires on these forests is likely large, since many of their tree species are not adapted to ...

Intermediate coupling between aboveground and belowground biomass maximises the persistence of grasslands [PDF]
, 2012 Aboveground and belowground biomass compartments of vegetation fulfil different functions and they are coupled by complex interactions. These compartments exchange water, carbon and nutrients and the belowground biomass compartment has the capacity to ...

Fire Histories and Rainforest Aboriginal Archaeology in the Wet Tropics Bioregion, North Queensland
Archaeology in Oceania, EarlyView.ABSTRACT Unlike the dominant Australian savanna‐sclerophyll vegetation, tropical rainforests do not burn easily. Any evidence of fire in Australian rainforests therefore invites explanations of its source. Analysis of 187 radiocarbon dates that include selected charcoal fragments from 23 soil pits and 7 archaeological sites from the Wet Tropics ...
