Invasive grasses of sub-Antarctic Marion Island respond to increasing temperatures at the expense of chilling tolerance.
TL;DR: Traits scaled linearly with rates of range expansion and demonstrate that under sub-Antarctic conditions, anthropogenic warming over the last 50 years may have favoured species with greater capacity to respond photosynthetically to warming to the detriment of species that cannot and negated the advantage that chilling tolerance would have conferred on endemic species in the past.
PDEMR Modelling of the Protea Rare Species Spatial Patterns
TL;DR: In this paper, the authors used frequency counts to deal with species presence data, then used the recently developed partial differential equation motivated regression (PDEMR) model to predict the unknown locations, and finally combine these data to produce a kriging prediction map.
Journal ArticleDOI
A cycad's non-saturating response to carbon dioxide enrichment indicates Cenozoic carbon limitation in pre-historic plants
TL;DR: The results suggest that growth and physiological performance of cycads have been severely compromised by declining [CO2] during the Cenozoic Era, possibly contributing to the current rare and endangered status of this functional type.
Journal ArticleDOI
Atmospheric CO2 concentrations restrict the growth of Oxalis pes-caprae bulbs used by human inhabitants of the Paleo-Agulhas plain during the Pleistocene glacials
TL;DR: The model suggests that an almost doubled foraging effort would have been required at glacial compared to current conditions, highlighting the need to consider plant growth conditions and particularly atmospheric CO2 concentrations when extrapolating current anthropological studies to the past.

Remotely sensed canopy height reveals three pantropical ecosystem states: a comment
Alexis D. Synodinos,David J. Eldridge,Katja Geißler,Florian Jeltsch,Dirk Lohmann,Guy F. Midgley,Niels Blaum +6 more
TL;DR: Using remotely sensed tree cover and canopy height measurements, Xu and colleagues conclude that savannas and forest represent alternative states due to their climatic overlap in moist conditions and that ‘treeless’ and savanna ecosystems do not occur in the same MAP range, and that an abrupt shift from one ecosystem state to the other occurs at 600 mm MAP.
