The influence of climate on average nitrogen export from large watersheds in the Northeastern Uniteon riverine nitrogen fluxes. Those watersheds that have higher precipitation and higher discharge export a greater fraction of the net anthropogenic inputs of nitrogen. This fractional export ranges from 10 to 15% of the nitrogen inputs in drier watersheds in the northeastern United States to over 3

Nutrient-chlorophyll relationships in tropical-subtropical lakes: do temperate models fit?,ak TP-Chl relationship in the tropical-subtropical systems. Systems had high average TN:TP ratios and neither a multiple regression with log TP and log TN nor separating systems with high TN:TP (>17 by weight) improved the predictive power of the log TP-log Chl relationship.

Misnomer

The stable carbon and nitrogen isotopic composition of vegetation in tropical forests of the Amazonpitation was similar among the studied sites. Leaf δ.N values ranged from+0.9‰ to a maximum value of+10.9‰, and the Santarém sites showed more enriched values than Manaus and Ji-Paraná sites. No seasonal variation was detected in the δ.N of leaves, but significant differences were observed among sit
