The effects of aerial microclimate and edaphic conditions on the growth of young vegetative tillers of Phleum alpinum L. from contrasting habitats on South Georgia have been investigated using growth analysis concepts. Relative growth rate (R w) was found to be negatively correlated with habitat severity, there being a strong relationship between R w and the amount of lateral production per Cited by: Ecophysiological and bioclimatic foundations for a global plant functional classification.

The simple single morphotype of Clusia gains diversity by the various life forms it produces (Sect. ) and by its high physiological and biochemical plasticity (Chap. 8).Clusia is extraordinarily successful in various tropical habitats as.

Ecophysiological parameters for biogeochemical models have been measured for Pacific Northwest tree species on a variety of sites with multiple age classes.

The taxonomic standing of Bifidobacterium lactis and Bifidobacterium animalis was investigated using a polyphasic approach.
