Quantitative studies typically avoid ecotones (Risser 1993) because they occur across spatial and temporal scales (Gosz 1993).
For example, litter often immobilizes nutrients (particularly nitrogen [N] and phosphorus [P]) early during decomposition, suggesting that fresh litter contains insufficient nutrients to meet the growth and maintenance requirements of decomposers (Gosz et al.

Previous studies of NUE have often found that NUE increases with diminishing N availability (Gosz, 1981; Lennon et al., 1985; Escudero et al., 1992; Reich et al., 1997).

As Gosz (1981) outlined, vegetation on N-rich sites produces litter with high N concentrations and low amounts of phenolics, leading to rapid decomposition and mineralization of N.
This again was an unexpected result because in a putatively phosphorus-limited ecosystem the prediction might be that the trees would conserve phosphorus by withdrawing and translocating it before abscission (Vitousek 1982, 1984, Melillo and Gosz 1983, Jordan 1985, Vitousek and Sanford 1986).
Such a high proportion of leaf litter has been observed by several authors (Gosz et al., 1972; Shure & Gottschalk, 1985; Cuffney, 1988) and was attributed to the big leaf area in these alluvial habitats (Shure & Gottschalk, 1985).
Desert ecosystems are characterized by particularly wide fluctuations in precipitation and plant-water relations (Noy-Mier, 1973; Crawford and Gosz, 1982; Kunkel et al., 1990; Schlesinger et al., 1990) and should provide a useful model of arthropod responses to a gradient of host conditions.
