Finally, highly significant differences of 15 N uptake were found for each form of N when it was provided in isolation relative to when it was provided in mixture Figs.

Ellison AM, Gotelli NJ 2002 Nitrogen availability alters the expression of carnivory in the northern pitcher plant Sarracenia purpurea.
Conclusions and Significance By taking up intact amino acids, Sarracenia purpurea can short-circuit the inorganic nitrogen cycle, thus minimizing potential bottlenecks in nitrogen availability that result from the plant's reliance for nitrogen mineralization on a seasonally reconstructed food web operating on infrequent and irregular prey capture.

Diet of contaminated insects harms endangered meat-eating plants. Similarly, there is pronounced spatiotemporal variation in the availability, form, quantity, and proportions of each form of N in bogs in general and in the Sarracenia microecosystem in particular.

July 7, 2009 Copyright: Nature 158: These inferences are supported by our results showing greater 15 N uptake from ON than from IN energetic benefit when each form was provided in isolation at Tom Swamp Fig. Uptake of different forms of nitrogen At each site, there were highly significant differences among treatments Fort Albany: Nature 171: Tsuji, E.
Although some vascular plants can assimilate organic nitrogen directly, only recently has organic nitrogen been found to contribute significantly to the nutrient budget of any plant.
