On the challenges of using field spectroscopy to measure the impact of soil type on leaf traits

Working with 24 chemical and physical leaf traits of six European tree species growing on strongly contrasting soil types (i.e. deep alluvium versus nearby shallow chalk), we asked whether variability in leaf traits is greater between tree species or soil type,
and whether field spectroscopy is effective at predicting intraspecific variation in leaf traits as well as interspecific differences.

Species- and community-level patterns in fine root traits along a 120 000-year soil chronosequence in temperate rain forest

Measurement of species- and community-level root and leaf trait responses for 50 temperate rainforest species from 28 families of ferns, woody and herbaceous angiosperms and conifers, along a soil chronosequence in New Zealand that exhibits a strong gradient in soil nutrient availability.

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.

A greater range of shade-tolerance niches in nutrient-rich forests: an explanation for positive richness–productivity relationships?

Investigating if a wider range of growth rates and shade tolerances are found on nutrient-rich soils, because such soils not only support fast-growing species with high metabolic rates, but also species capable of tolerating the very deep shade cast by forest canopies growing where nutrients are plentiful.

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.

Long-Term Effects of Wild fire on Ecosystem Properties Across an Island Area Gradient

Boreal forest soils play an important role in the global carbon cycle by functioning as a large terrestrial carbon sink or source, and the alteration of fire regime through global change phenomena may influence this role. In this study a system of forested lake islands in the boreal zone of Sweden for which fire frequency increases with increasing island size was investigated for evidence of environmental factors being influenced by fire frequency.
