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. Wright, D.M.; Jordan, G.J.; Lee, W.G.; Duncan, R.P.; Forsyth, D.M.; Coomes,Continue reading “Do leaves of plants on phosphorus-impoverished soils contain high concentrations of phenolic defence compounds?”
Seeing the forest for the deer: Do reductions in deer-disturbance lead to forest recovery?
Despite significant and sustained deer herd reductions between 1996 and 2009, there was limited recruitment of small trees and declines in basal area of tree species that were sensitive to deer browsing. Tanzentap, A. et al. 2010 PDF
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
Assessing the impacts of fragmentation on plant communities in New Zealand: scaling from survey plots to landscapes
Attempted to assess the overall impact of fragmentation at the landscape scale. We quantify the impacts of fragmentation on plant diversity by assessing patterns of community composition in relation to a range of fragmentation measures. Lafortezza, R.; Coomes, D.A.; Kapos, V.; Ewers, R.M. 2010 PDF
Influences of Forest Structure, Climate and Species Composition on Tree Mortality across the Eastern US
Using Bayesian analysis of over 430,000 tree records from a large eastern US forest database we characterised tree mortality as a function of climate, soils, species and size (stem diameter). Lines, E.R.; Coomes, D.A.; Purves, D.W. 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
Disturbance affects short-term facilitation,but not long-term saturation, of exotic plant invasion in New Zealand forest
We investigate the spread of an exotic herb, Hieracium lepidulum, into a New Zealand Nothofagus forest with the aim of understanding how stand-development of tree populations, propagule pressure and invader persistence, affect invasion across the landscape and within communities.
