Qualitative models on stream ecosystem recovery: exploratory studies
Most of water ecosystems are endangered by human actions, in spite of their importance for all living systems. Qualitative models and simulations may be useful for stream ecosystem recovery in many ways: for understanding such systems, to predict values of variables and to combine such understanding with restoration and proactive actions of management. This study describes the development of qu...
متن کاملRapid Recovery of Damaged Ecosystems
BACKGROUND Recent reports on the state of the global environment provide evidence that humankind is inflicting great damage to the very ecosystems that support human livelihoods. The reports further predict that ecosystems will take centuries to recover from damages if they recover at all. Accordingly, there is despair that we are passing on a legacy of irreparable damage to future generations ...
متن کاملDenitrification in a nitrogen-limited stream ecosystem
Denitrification was measured in hyporheic, parafluvial, and bank sediments of Sycamore Creek, Arizona, a nitrogen-limited Sonoran Desert stream. We used three variations of the acetylene block technique to estimate denitrification rates, and compared these estimates to rates of nitrate production through nitrification. Subsurface sediments of Sycamore Creek are typically well-oxygenated, relati...
متن کاملStream Data Mining: A Survey
A data stream is a massive, continuous and rapid sequence of data elements. Mining data streams raises new problems for the data mining community about how to mine continuous high-speed data items that you can only have one look at. Due to this reason, traditional data mining approach is replaced by systems of some special characteristics, such as continuous arrival in multiple, rapid, time-var...
متن کاملRiparian deforestation, stream narrowing, and loss of stream ecosystem services.
A study of 16 streams in eastern North America shows that riparian deforestation causes channel narrowing, which reduces the total amount of stream habitat and ecosystem per unit channel length and compromises in-stream processing of pollutants. Wide forest reaches had more macroinvertebrates, total ecosystem processing of organic matter, and nitrogen uptake per unit channel length than contigu...
