Effects of size, competition and altitude on tree growth

An exploration of the factors regulating the diameter growth of 3334 trees of mountain beech growing in natural single-species forests in New Zealand. Maximum-likelihood modelling was used to quantify the influences of tree size, altitude, the basal area of taller neighbours (BL) and the basal area of all neighbours (BT) on growth. Coomes, D.A.; Allen,…

Resistance and resilience of New Zealand tree species to browsing

A prominent idea in the literature on plant–herbivore interactions is that fast-growing species have low resistance but high resilience to herbivory. Fast-growing species are selectively eaten by herbivores but recover quickly following damage. This is an analysis whether this resistance-resilience trade-off applies to New Zealand woody species, which evolved without exposure to mammalian herbivores. BEE, J.N.;…

Rapid deforestation and fragmentation of Chilean Temperate Forests

Three land-cover maps were derived from satellite imagery acquired over 25 years (1975, 1990 and 2000), and were used to assess the patterns of deforestation and forest fragmentation in the coastal range of south-central Chile. Between 1975 and 2000, there was a reduction in natural forest area of 67% in the study area, which is…

Challenges to the generality of WBE theory

A critique of the use of WBE as a general tool with proposals that more complex models are necessary to accurately deal with the environmentally influential factors which effect natural forest communities. Coomes, D.A. 2006 PDF
