Macrophyte management: An integrated perspective

A concept of aquatic macrophyte management that integrates the positive and negative aspects of vegetation in lakes and rivers is discussed. This integrated approach involves three factors: macrophyte control, macrophyte enhancement, and identification and resolution of the conflicts created by multiple use of a waterbody. The primary decision in macrophyte management programmes must be whether to optimise for single‐purpose or for multipurpose use of the waterbody. Both technical (macrophyte control and enhancement) and social (conflict resolution) procedures are required to solve problems associated with the macrophyte status of multipurpose waterbodies.

Volcanic Ash as a Source of Dissolved Phosphorus in the Ocean

The process of phosphorus migration from volcanic ash and obsidian to seawater was experimentally studied. For obsidian and ash of the Ksudach, Karymskiy, and Eyjafjallajökull volcanoes, the specific mobilization of phosphorus ranges from 0.3 to 5.0 µg P/g with an average value of ～1.5 µg P/g. The maximum dissolved mineral phosphorus input into the ocean as a result of the interaction between pyroclastic material from arc volcanism and seawater is 4500–9000 t/yr, which does not exceed 0.3–0.6% of its input from river runoff.
