"We've already tried comparative analysis using ecosystem structures and hydrofluid reaction dynamics."

Invasive species can greatly impact the ecosystem structure and function of riparian zones.

However, the ecosystem structure is significantly rearranged, with the abundances and distributions of different groups of plants changing profoundly.

Deterioration of the kelp itself results in the loss of physical ecosystem structure and subsequently, the loss of other species associated with this habitat.

Disturbance is followed by succession, a "directional change in ecosystem structure and functioning resulting from biotically driven changes in resources supply."

Major changes in ecosystem structure and function, including hydrologic processes, are expected with the loss of hemlock.

Consequently, there is no data on the past ecosystem structure and the hypothesis cannot be tested.

Therefore, the roles of predation and food/nutrient processes in influencing ecosystem structures remain open to controversy and further testing.

Non-native species can have profound effects on ecosystems by changing ecosystem structure, function, species abundance, and community composition.

Much of his work concerns the evolution of diversification, the mechanisms sustaining biological diversity in natural systems, and the implications for ecosystem structure and functioning.
