BACKGROUND Large-scale plant diversity inventories are critical to develop informed conservation strategies. However, the workload required for classic taxonomic surveys remains high and is particularly problematic for megadiverse tropical forests. METHODOLOGY/PRINCIPAL FINDINGS Based on a comprehensive census of all trees in two hectares of a tropical(More)
Arbuscular mycorrhizal fungi (AMF) form symbioses with most plant species. They are ecologically important determinants of plant growth and diversity. Considerable genetic variation occurs in AMF populations. Thus, plants are exposed to AMF of varying relatedness to each other. Very little is known about either the effects of coexisting AMF on plant growth(More)
, The prevailing paradigm has been that climate variability and change can be projected decades or even a century or more into the future (e.g. IPCC 1996, 2001). However, for several reasons-e.g. imperfect representation of the full complexity of the Earth system, non-linear spatial and temporal feedbacks, and imperfect foresight of human behaviour, it may(More)
