The introduction of non-native people knowledge and skills can also cause substantial shifts in the ecosystem functions.

There also remains the unanswered question of just how many species are required for any given set of ecosystem functions.

Biomass productivity is one of the most apparent and economically important ecosystem functions.

Most of the focus is on the impacts caused to many of the ecosystem functions and processes.

As an aside, the f-ratio can also reveal important aspects of local ecosystem function.

The introduction of non-native species can cause substantial shifts in ecosystem function.

The remaining biomass is needed to maintain ecosystem functions and diversity.

Most conservation scientists assess the dramatic decline in species by the impact on ecosystem function.

The key difference is the rate at which the loss of species affects total ecosystem function.

Other aspects of ecosystem function like respiration and primary production were also affected.
