Ecosystem Ecology
Floristic succession in the boreal forest can have a dramatic influence on ecosystem nutrient cycling. We predicted that a decrease in plant and microbial demand for nitrogen (N) during the transition from midto late-succession forests would induce an increase in the leaching of dissolved inorganic nitrogen (DIN), relative to dissolved organic nitrogen (DON). To test this, we examined the chemi...

Amazonian forest fragments and secondgrowth forests often differ substantially from undisturbed forests in their microclimate, plant-species composition, and soil fauna. To determine if these changes could affect litter decomposition, we quantified the mass loss of two contrasting leaf-litter mixtures, in the presence or absence of soil macroinvertebrates, and in three forest habitats. Leaf-lit...

Nitrogen isotopes (N/N ratios, expressed as dN values) are useful markers of the mycorrhizal role in plant nitrogen supply because discrimination against N during creation of transfer compounds within mycorrhizal fungi decreases the N/N in plants (low dN) and increases the N/N of the fungi (high dN). Analytical models of N distribution would be helpful in interpreting dN patterns in fungi and p...

In the two decades following the 1980 eruption of Mount St. Helens in Washington State, the N2-fixing colonizer Lupinus lepidus is associated with striking heterogeneity in plant community and soil development. We report on differences in nutrient availability and plant tissue chemistry between older, dense patches (core) of L. lepidus and more recently established low density patches (edge). I...
