Limiting and Experimental Factors
Practical applications of phytoremediation are essential for the clean-up of moderately and severely contaminated sites in an economical and environmentally responsible way. The usage of plants to do a job that would otherwise be done by chemicals or energy intensive soil removal is a natural choice on several levels. First, by using plants for clean-up, pollutants are being absorbed by nature ...
متن کاملLimiting factors and population regulation
The great debate over the meaning and relevance of population regulation lingers on under the perceived difference between limitation and regulation of animal numbers / what Murray (1999) calls the ‘‘population limitation hypothesis’’ versus the ‘‘density dependent regulation hypothesis’’. Berryman et al. (2002) attempt to solve this dilemma by (1) arguing that the problem is partly caused by a...
متن کاملFactors limiting bioremediation technologies
The use of microorganisms to destroy, or reduce the concentration of, hazardous wastes on a contaminated site is called bioremediation. Such a biological treatment system has various applications, including, clean up of contaminated sites such as water, soils, sludges, and waste streams. The treatment of the Alaskan shoreline of Prince Williams Sound after the oil spill of Exxon Valdez in 1989 ...
متن کاملFactors Limiting Bacterial Growth
Simple assumptions have led to equations by which the latent period in multiplication and the bacterial numbers expected at any time during the phase of rapid growth may be predicted. Experimental data obtained under rather diverse conditions have given satisfactory agreement with calculated values. Since the mathematical expressions contain no arbitrary constants, more than accidental signific...
متن کاملFactors Limiting Feed
T HE mechanisms regulating feed intake appear to be the same mechanisms that control energy exchange. The physiological functions brought into play are numerous and involve chemosensitive areas, reflex responses and integrative function of the central nervous system. Aside from the primary physiological factors limiting feed intake, a close relationship exists in ruminants between the content o...
