Ecosystem Function and Ecosystem Management
1997Surely the most sobering, if not daunting, lesson to emerge from millennia of natural resource use and a century of ecological study is that the laws of conservation of mass and energy apply to the ecological systems we depend upon for natural resources and to the environmental conditions that shape the quality of our lives.

This chapter explores how the mathematical frameworks, empirical methods, and predictions introduced for community structure can be extended to ecosystem function. Also outlined is an alternative conceptual framework (biological stoichiometry) for evaluating eco-evolutionary dynamics at the ecosystem level.

Monitoring of the functioning of ecosystems
Environmental Monitoring and Assessment, 1981The theoretical basis, the content and the possible applications of the program 'Monitoring of ecosystems' are considered. A functional definition of ecosystem is proposed, and some features of ecosystems are defined on this basis. The program 'Monitoring of ecosystems' is visualized as a large-scale program of simple measurements of the rates of the ...

Spatial Pattern of Ecosystem Function and Ecosystem Conservation
Environmental Management, 2003The spatial pattern of ecosystem function can affect ecosystem conservation. Ecosystem functions are often heterogeneous spatially due to physical and biological factors. We can influence ecosystem functions by changing the spatial patterns of the physical and biological elements of an ecosystem and regulating their combinations. The variation-position

Biodiversity and ecosystem function in constructed ecosystems.
CABI Reviews, 2008Abstract Constructed ecosystems are engineered to perform functions, such as bioremediation of contaminants, and are increasingly viewed as green alternatives to conventional technologies. Augmenting biodiversity of managed systems such as agroecosystems has been shown to improve yields and other functions such as nutrient uptake, but

An important aspect of all aquatic subterranean ecosystems is the nature and connectivity of surface inputs. A theme common to both is heterogeneity of inputs that exist at even the smallest scale. At least in cave streams, carbon appears to be limiting. Studies at the scale of entire caves are of two very different kinds. For caves with surface inputs,

Ecosystem Functions and Ecosystem Values
1997Our understanding of how ecosystems function has expanded enormously since the term was first defined as a dynamical system consisting of a biological entity, typically a regional biota (community), together with its environment by Alfred George Tansley in 1935.

Phylogenetic diversity and the functioning of ecosystems
Ecology Letters, 2012Abstract Phylogenetic diversity ( PD ) describes the total amount of phylogenetic distance among species in a community. Although there has been substantial research on the factors that determine community PD , exploration of the ...

In the face of decreasing biodiversity and ongoing global changes, maintaining ecosystem functioning is seen both as a means to preserve biological diversity as well as for safeguarding human well-being by securing the services ecosystems provide. The concept today is prominent in many fields of ecology and conservation biology, such as biodiversity ...

Obscuring Ecosystem Function with Application of the Ecosystem Services Concept
Conservation Biology, 2010Abstract: Conservationists commonly have framed ecological concerns in economic terms to garner political support for conservation and to increase public interest in preserving global biodiversity. Beginning in the early 1980s, conservation biologists adapted neoliberal economics to reframe ecosystem functions ...
