Microbes losing themselves in Heat
In
this article presented by Nydahl, it is shown how the coastal zone is the
productive area of the marine environment. In the article it is shown how
climate change, increased temperature and precipitation are expected to
influence the coastal food web. This experiment used a dark bottle as an
incubation to show the short – term interactive effects of changes in salinity,
temperature and riverine dissolved organic matter.in this there was found to be
more microbial respiration, growth and abundance in the estuarine community. In the research, it was shown that when there was an
increase in temperature, there was a reduction in bacterial abundance. Essentially,
the study showed that hypoxia had the probability to increase in coastal zones
due to respiration enhancement that are brought on by higher temperatures.
