Ascendency as Ecological Indicator for Environmental Quality Assessment at the ...
Patrício, J.; Ulanowicz, R.; Pardal, M.; Marques, J.Previous studies have shown that when an ecosystem consists of many interacting components it becomes impossible to understand how it functions by focussing only on individual relationships. Alternatively, one can attempt to quantify system behaviour as a whole by developing ecological indicators that combine numerous environmental factors into a single value. One such holistic measure, called the system ‘ascen...
Ascendency as an ecological indicator: a case study of estuarine pulse eutrophi...
Patrício, J.; Ulanowicz, R.; Pardal, M. A.; Marques, J. C.Increasingly, management agencies require that the remediation of eutrophic waters be addressed at the level of the whole ecosystem. One whole-system approach to quantify ecosystems is called ecological network analysis. Ascendency theory, the branch of the field that deals with the quantification of whole-system status, specifically addresses the definition of eutrophication. This definition has been applied t...
