▪ Abstract The use of stable isotope techniques in plant ecological research has grown
steadily during the past two decades. This trend will continue as investigators realize that …

Mycorrhizae play a critical role in nutrient capture from soils. Arbuscular mycorrhizae (AM)
and ectomycorrhizae (EM) are the most important mycorrhizae in agricultural and natural …

We assembled a globally-derived data set for site-averaged foliar δ15N, the δ15N of whole
surface mineral soil and corresponding site factors (mean annual rainfall and temperature …

Aims Mycorrhizas (fungal roots) play vital roles in plant nutrient acquisition, performance and
productivity in terrestrial ecosystems. Arbuscular mycorrhizas (AM) and ectomycorrhizas …

Ectomycorrhizal fungal species vary in their response to nitrogen (N) availability and ability
to use organic N. We hypothesized that taxa dominant at sites with high soil inorganic N …

To integrate the complex physiological responses of plants to stress, natural abundances (δ)
of the stable isotope pairs 15 N/14 N and 13 C/12 C were measured in 30 genotypes of wild …

The natural abundance of stable 15 N isotopes in soils and plants is potentially a simple tool
to assess ecosystem N dynamics. Several open questions remain, however, in particular …

Red deer bone collagen from Rochedane in the Jura (France) was analysed for carbon and
nitrogen isotopic composition. The specimens range in 14C age from about 13 000 to 8000 …

The% N and δ 15N values of soils and plants were measured along a chronosequence
spanning 3 to 3000 Ky in a California annual grassland. Total soil N decreased with …

Of all the techniques used in modern plant ecology, those that apply stable isotopes are
amongst the most powerful. Previously the preserve of geochemists and physiologists owing …
