Do leaves of plants on phosphorus-impoverished soils contain high concentrations of phenolic defence compounds?

Comparing the foliar concentrations of phenolic compounds in phenotypes of 21 species growing on P-rich alluvial terraces and P-depleted marine terraces in southern New Zealand, and 87 species growing under similar climates on comparatively P-rich soils in New Zealand vs. P-depleted soils in Tasmania.

Interspecific relationships among growth, mortality and xylem traits of woody species from New Zealand

Testing the hypotheses that there is a set of inter-related trade-offs linked to the different functions of wood, that these trade-offs have direct consequences for tree growth and survival and that these trade-offs underlie the observed correlations between wood density and demographic rates. Russo, S.E.; Jenkins, K.L.; Wiser, S.K.; Uriarte, M.; Duncan, R.P.; Coomes, D.A.Continue reading “Interspecific relationships among growth, mortality and xylem traits of woody species from New Zealand”

Biodiversity Conservation: Challenges Beyond 2010

An argument that effective conservation of biodiversity is essential for human survival and the maintenance of ecosystem processes. Despite some conservation successes (especially at local scales) and increasing public and government interest in living sustainably, biodiversity continues to decline. Rands, M.R.W et al 2010 PDF

Podocarpaceae in Tropical Forests: A Synthesis

A paper exploring the origins of Podocarpaceae in Tropical Forests, how at risk they are as genera within a family and the implications for their conservation. Cernusak, L.A. et al. 2010 PDF

Evolution of the climatic niche in scaly tree ferns (Cyatheaceae, Polypodiopsida)

A reconstruction a climatic niche of scaly tree ferns (Cyatheaceae) using a rigorous analytical procedure which combines climatic niche modelling with reconstruction of continuous characters given a phylogenetic hypothesis. To estimate the limits to climatic niches of species, we used climate envelope modelling and ordination. BYSTRIAKOVA, N.; SCHNEIDER, H.; COOMES, D. 2010 PDF
