Efficient selection for specific culinary and nutritional quality traits needs a better understanding of the genetic and environmental control of quality traits at the structural, physiological and biochemical levels. Field experiments indicate great variability in the Phaseolus gene pool regarding the content of antinutritional compounds, as well as in cooking characteristics of the seeds. The...

The ecological mechanisms driving community succession are widely debated, particularly for microorganisms. While successional soil microbial communities are known to undergo predictable changes in structure concomitant with shifts in a variety of edaphic properties, the causal mechanisms underlying these patterns are poorly understood. Thus, to specifically isolate how nutrients--important dri...

Although rain forest is characterized as pyrophobic, pyrophilic giant eucalypts grow as rain forest emergents in both temperate and tropical Australia. In temperate Australia, such eucalypts depend on extensive, infrequent fires to produce conditions suitable for seedling growth. Little is known, however, about constraints on seedlings of tropical giant eucalypts. We tested whether seedlings of...

Lasthenia californica sensu Ornduff consists of two races that differ in their flavonoid pigments and edaphic tolerances. Recent phylogenetic studies of Lasthenia have revealed that members of L. californica sensu Ornduff belong to two phylogenetic species. The relationship of the edaphic races to these new species and to each other is the focus of this study. Characterization of flavonoid prof...

Fertilizations affect soil organic carbon (SOC) content but the relative influences of the edaphic and climate factors on SOC storage are rarely studied across wide spatiotemporal scales. This study synthesized long-term datasets of fertilization experiments in six typical Chinese croplands, and calculated annual C input from crops and manure amendments, changes in SOC storage (ΔSOC) and C sequ...

MUNISHI, P. K. T., SHEAR, T. H., WENTWORTH, T. & TEMU, R. A. P. C. 2007. Compositional gradients of plant communities in submontane rainforests of eastern Tanzania. This study classified plant communities and examined the environmental correlates of community compositions in two submontane rainforests on the ranges of Eastern Arc Mountains, Tanzania. Using agglomerative cluster analysis, indica...
