Nitrate retention and removal in Mediterranean streams bordered by contrasting land uses:a 15N tracer study
Nitrate retention removal Mediterranean streams contrasting land uses 15N tracer
2010/1/19
We used 15N-labelled nitrate (NO3−) additions to investigate pathways of nitrogen (N) cycling at the whole-reach scale in three stream reaches with adjacent forested, urban and agricultural land...
Food web responses to low-level nutrient and 15N-tracer additions in the littoral zone of an oligotrophic dune lake
Food web responses low-level nutrient 15N-tracer additions littoral zone oligotrophic dune lake
