It has also triggered an ecological chain reaction there, resulting in, among other impacts, record numbers of rabies cases.
Floods wash excess nitrogen into the gulf, triggering algae blooms and an ecological chain reaction that reduces oxygen levels and suffocates sea life (Science, 10 July 1998, p. 190).
This is the first example they have encountered of an ecological 'chain reaction,' in which a change that directly affects one species has an indirect effect on another species a simplified version of the subtle but significant and often unanticipated cascades that have been observed in many ecosystems.
This new understanding will allow us to design conservation programs, perform restoration of damaged or degraded areas, and address resource management concerns (e.g., agriculture, logging, mining, hunting) more effectively than with the current approach of ad hoc reactions to ecological and environmental problems.
But the worldwide reaction to continuing ecological devastation was sharp.
MCM extends Harcombe et al.'s framework to more versatile microbial ecological models that include arbitrary reaction kinetics (e.g., subject to product-inhibition) as well as dynamical environmental variables (e.g., pH) that influence, and are influenced by, microbial metabolism.
Indicator values for lichens exist for the ecological factors light, temperature, continentality, moisture, reaction and nitrogen.
It has been recognized for many decades that the stoichiometry of biological reactions is important for linking ecological and biogeochemical processes.
However, Synechocystis 6803 is also widely used in fundamental research on ecological or photophysiological questions and to unravel the reactions and metabolites of photosynthetic primary metabolism.
Based on a first-order reaction model extensively employed in related ecological risk assessment and environmental hydraulic design, the effect of ecological degradation is separated from the hydraulic effect via an exponential transformation for the general formulation for contaminant transport.
