Kauri (Agathis australis (D. Don) Lindl.) occurs naturally in the warm temperate forest of northern New Zealand where it grows mixed with angiosperm tree species. Below mature kauri trees thick organic layers develop in which large amounts of nitrogen are accumulated. This nitrogen seems to be inaccessible to plants. While litter quality can explain the low decomposition rate below kauri, it is not known what causes the accumulation of nitrogen. We hypothesised that kauri tannins reduce… Expand

Low soil water and nutrient availability below New Zealand kauri (Agathis australis (D. Don) Lindl.) trees increase the relative fitness of kauri seedlings
Low soil moistureavailability, or the combination of low soil moisture availability and low nutrient fertility, hampers the growth of kauri as well as mapau seedlings below kauri trees. Expand
Dissolved and particulate carbon and nitrogen fluxes along a Phytophthora agathidicida infection gradient in a kauri (Agathis australis) dominated forest
The observed alteration in dissolved and particulate C and N fluxes under P. agathidicida infected kauri trees could lead to long-term changes in biogeochemical processes in these ecologically unique kauri forests. Expand
Do late-successional tannin-rich plant communities occurring on highly acidic soils increase the DON/DIN ratio?
Previous studies suggested that late-successional tannin-rich plant communities increase the amount of dissolved organic N (DON) relative to dissolved inorganic N (DIN) in decomposing litter. WeExpand
The effects of condensed tannins derived from senescing Rhizophora mangle leaves on carbon, nitrogen and phosphorus mineralization in a Distichlis spicata salt marsh soil
Background and aimsDue to global warming, it is to be expected that mangroves will move north- and southwards and enter salt marshes, which will then be enriched with mangrove-derived organicExpand
Net nitrogen mineralization and enzyme activities in an alpine meadow soil amended with litter tannins
Condensed tannins in plant litter play an important role in soil nitrogen (N) cycling at the plant–soil interface. However, how soil net N mineralization is affected by litter tannins through theirExpand
Growth responses of five forest plant species to the soils formed beneath New Zealand kauri (Agathis australis)
Compared soils under kauri and adjacent broadleaved forest on the growth and nitrogen status of five forest plant species of varying levels of association with kauri are consistent with a link between kauri-induced soil conditions and plant community composition. Expand
Abundance and diversity of total and nitrifying prokaryotes as influenced by biochemical quality of organic inputs, mineral nitrogen fertilizer and soil texture in tropical agro-ecosystems
Tropical agro-ecosystems are limited in nutrient resources as a consequence of i) being composed of highly weathered soils, ii) low native soil organic matter (SOM) content due to conversion ofExpand
Kauri trees (Agathis australis) affect nutrient, water and light availability for their seedlings
Kauri seedlings are more tolerant of drought and low nutrient availability than other tree seedlings and it is suggested that periodic drought explains why the density of kauri seedling under mature kauri trees is less than in tea tree vegetation. Expand
Slow decomposition of leaf litter from mature Fagus sylvatica trees promotes offspring nitrogen acquisition by interacting with ectomycorrhizal fungi
Increasing N retention within the recalcitrant N forms in soil was identified as a key mechanism by which beech alters soil N cycling with potential positive feedbacks on its acquisition by the plant. Expand
Site conditions affect seedling distribution below and outside the crown of kauri trees (Agathis australis)
The results confirm the hypotheses and indicate that the establishment of kauri seedlings is favoured by the open canopy and high light intensities below kauri, suggesting that a positive feedback between kauri and the soil is likely. Expand


Carbon and nitrogen dynamics in a forest soil amended with purified tannins from different plant species
Tannins are purported to be an important factor controlling nitrogen cycling in forest ecosystems, and the ability of tannins to bind proteins in protein–tannin complexes is thought to be the primaryExpand
Influence of balsam poplar tannin fractions on carbon and nitrogen dynamics in Alaskan taiga floodplain soils
High molecular weight tannin fractions appeared to act primarily by binding extracellular substrates and thus limiting C and N mineralization, with the strongest effects observed in the alder soils. Expand
Decomposition of litter from common woody species of kauri (Agathis australis Salisb.) forest in northern New Zealand
Investigation of rates of weight loss and release of Na, K, Ca, Mg and P for common components of kauri forest litterfall in experiments using mesh bags found loss of weight and nutrients was faster for freshly picked green leaves than for senesced leaves. Expand
Effects of balsam poplar (Populus balsamifera) tannins and low molecular weight phenolics on microbial activity in taiga floodplain soil: implications for changes in N cycling during succession
By inhibiting mineralization while stimulating immobilization, poplar secondary compounds may reduce soil N-availability during the transition betwen alder and poplar stages in interior Alaska. Expand

There is a close linear relationship between both stem productivity and litter production and maximum foliage N in any stand and this has important implications for management of kauri forest. Expand
Polyphenols as Regulators of Plant-litter-soil Interactions in Northern California's Pygmy Forest: A Positive Feedback?
Although their long-accepted adaptive value for antiherbivore defense is now in doubt, polyphenol alteration of soil conditions and regulation of nutrient cycling illustrate how fitness can be influenced by the ‘extended’ phenotype in plant-litter-soil interactions. Expand

Abstract Kauri ( Agathis australis ) is generally associated with intense podzolisation, but little research has been carried out to substantiate this. We studied soil profiles, grain sizeExpand
