1.5Soil Organic Carbon is a Major Driver of Ecosystem Services Ecosystem functionsinclude the physicochemical and biological processes that occur within the ecosystem to maintain terrestrial life. Ecosystem services are the set of ecosystem functions thatare directly linked to benefit human well-being (Kr...
“How does the knowledge brokerage function of ecotones evolve to meet the needs of academic research and policy ecosystems?”To answer our research question, we took an ecosystem perspective and conducted a phenomenological study to explore how the knowledge brokerage function might evolve over the ...
First, if there are more species in an ecosystem, then its food web will be more complex, with greater redundancy among species in terms of their nutritional roles. In other words, in a rich system if a species is lost, there is a good chance that other species will take over its ...
Understanding how these ecosystem services – and the ecosystem properties underpinning them – respond to drivers of change is therefore an urgent priority. We address this challenge through developing a novel risk-assessment framework that integrates ecological and evolutionary perspectives on functional ...
