Effect of UV on Productivity of the Southern Ocean. Has ozone depletion over Antarctica affected the productivity of the Southern Ocean There is no easy answer. First, one has to take into account the fact that the drastic decrease of ozone over Antarctica has been reported as recently as 1976, a relatively short time in the evolution of the organisms to develop mechanisms to cope with elevated UV. One of the most vexing problems in studying the effects of UV radiation on productivity, is a dearth of historical data on the level of UV. Without these baselines, normal fluctuations could easily be interpreted as decline in productivity. Second, there is a host of biotic and abiotic factors that play significant roles in governing the productivity of the Southern Ocean (40). Ultraviolet radiation is but one more complicating factor to be considered in an already stressful environment. 

The nature of the compounds in the exudate can be altered by biotic and abiotic factors experienced by the plant. Factors involved in quantitative or qualitative changes in exudates are ...

If all biotic and abiotic factors can be controlled, genetic influence is one of the major features responsible for differences in phytochemical composition. Several reviews on diverse compounds have reported the genetic influence on phytochemicals, sometimes to a surprising order of magnitude. The influence of cultivar can be even greater than the influence of growth conditions, thus complicating the data analyses for plant composition.

In order to understand the factors that limit microbial activity in the microenvironments of aqueous-solid phase interfaces, it is necessary that biotic and abiotic factors be discussed. These factors include the following. 

Interactions between plants and microorganisms in remediation must be studied further and with greater attention, because in many contaminated sites they both can be beneficial if applied simultaneously, and synergy may enhance the individual site cleanup and reduce costs.. This holistic approach considers interactions in the environment, not only between organisms, but also between contaminants, and between biotic and abiotic factors.
