This template gives you a general idea of the layout of your page. You are not completely restricted to this format, so feel free to try out different things. I'll give you feedback as you work on your pages. Make sure to copy the "code" of this page to your own page before editing. -Prof Kent
In the introduction, briefly describe the habitat that is the topic of this page. Introduce the habitat, its ecological significance, and the importance of microorganisms in this environment. (What processes do they carry out? What functions do they perform?)
Mangroves are highly productive ecosystems. Mangrove swamps cover roughly 60-75% of the world’s tropical coastlines, distributed over more than 112 countries with a total area near 181,000km2. In general mangroves are nutrient-deficient. However, mangrove litter decomposition and the nutrient release which accompanies it is a vital part of the function of adjacent coastal ecosystems. Sediment microorganisms play important roles in the mangrove ecosystem and make essential contributions to its productivity.
Physical environment
Describe the physical and chemical characteristics of the environment, using as many sections/subsections as you require. Look at other topics available in MicrobeWiki. Which involve processes similar to yours? Create links where relevant.
Subsection 1
Subsection 1a
Subsection 1b
Subsection 2
Biological interactions
Are there important biological interactions that are important in this environment? Do these interactions influence microbial populations and their activities? How do these interactions influence other organisms? Describe biological interactions that might take place in this environment, using as many sections/subsections as you require. Look at other topics available in MicrobeWiki. Create links where relevant.
Subsection 1
Subsection 1a
Subsection 1b
Subsection 2
Microbial processes
What microbial processes define this environment? Describe microbial processes that are important in this habitat, adding sections/subsections as needed. Look at other topics in MicrobeWiki. Are some of these processes already described? Create links where relevant.
Nitrogen Fixation
Nitrogen fixation is the process of conversion of gaseous forms of Nitrogen [N2] into combined forms such as ammonia or organic nitrogen. This process is generally carried out by some bacteria or cyanobacteria. Nitrogen fixation in mangrove sediment is likely to be hindered by a limited supply of energy sources.
Sulfate Reduction
Sulfate reduction is use of sulfate as an oxidizing agent and reducing it to sulfide. This is an anaerobic alternative to respriration. Since mangrove sediments are primarily anaerobic with a thin aerobic zone near the surface, sulfate reduction becomes the primary pathway of decomposition in the anaerobic zone of the sediments.
Phosphate Solubilization
Key Microorganisms
What kind of microbes do we typically find in this environment? Or associated with important processes in this environment? Describe key groups of microbes that we find in this environment, and any special adaptations they may have evolved to survive in this environment. Add sections/subsections as needed. Look at other microbe listings in MicrobeWiki. Are some of the groups of microbes from your environment already described? Create links to those pages. Specific microbial populations will be included in the next section.

Subsection 1b
Subsection 2
Examples of organisms within the group
List examples of specific microbes that represent key groups or are associated with important processes found in this environment. Link to other MicrobeWiki pages where possible.
