Bioturbators as Ecosystem Engineers: Control of the Sediment Fabric, Inter-Individual Interactions, in muddy sediment are competitions between the activities of microbes, which usually consume oxygen, and the activities of burrowing sediment consumers, which usually bring oxygen to the sediment by mixing of surface sediment with the overlying water or by irrigating burrows. Alterations of the sed

After prolonged low flow during drought, or in regulated channels with artificially stabilized hydrographs, lower trophic levels become dominated by armored or sessile taxa that are relatively invulnerable to predators

Population Variability in Experimental EcosystemsThe most variable zoo-plankton populations were those most susceptible to fish predation. Ecosystem level changes clearly affect population dynamics, and shifts in populations can have strong impacts on ecosystem processes such as primary production. Integration of population and ecosystem studies s

However, in the absence of evidence of stronger control of tree population dynamics by ecosystem processes and physical factors, we conclude that the spatial and temporal dynamic

The effects of these artifacts, most notably those created by earthworms and termites, are cumulative and can therefore be manifested in macroscale measurements. It is shown, however
