Key Concepts

Ecosystem Functioning

Ecosystem functioning involves the biological, geochemical, and physical processes and interactions that take place within an ecosystem, such as plant production, nutrient cycling, and energy flow. These processes are interdependent and are often stabilized by diverse species interactions, meaning that reductions in biodiversity can lead to diminished or less stable functioning.

Ecosystem Resilience

Ecosystem resilience is the ability of an ecosystem to absorb disturbances and reorganize while undergoing change so that it retains essentially the same functions, structure, and feedbacks. A diverse biological community generally enhances resilience by providing functional redundancy, which buffers the ecosystem against environmental perturbations like drought or other climatic extremes.

Biodiversity

Biodiversity refers to the variety and variability of life forms within a given ecosystem, region, or on the entire Earth. It encompasses the number of species, their genetic differences, and the ecosystems they form. A rich biodiversity contributes to a robust and adaptable ecological community capable of sustaining various functions and services.

Variability in Ecosystem Processes

Variability in ecosystem processes refers to the degree of fluctuation in ecological functions over time. This variability can increase when biodiversity declines because there are fewer species to perform key roles consistently, leading to unpredictable changes in processes such as plant productivity, water use, and pest and disease dynamics.
