Future studies/plans
Future studies will attempt to evaluate different sediments and nutrient levels. Mangroves will be placed on timer systems to mimic natural light cycles. Additional studies will include creating a mangrove forest in our wet lab to evaluate mangrove growth on a large scale. Finally, different species (worms, amphipods) will be used as indicators of increasing mangrove growth and restoration.

Are Fiddler Crabs a Keystone Species In Local Mangrove Forests?
After analyzing the results, the data proved that the mangroves that were in mud with the fiddler crabs grew the most. Based off of the results, a substantial amount of the fiddler crabs and mangroves died. This may be because instead of using a certain amount of water or light I just put an amount I thought would be ok.

Are Fiddler Crabs a Keystone Species In Local Mangrove Forests?
1) Collect sand and mud, fiddler crabs and mangroves
2) Put mud and sand in a aluminum pan, bake for 24 hours to purify
3) Put equal amounts of mud and sand in all cups (n=15) and the mud (n=15)
4) Fifteen cups of sand and mud containing crabs.
Fifteen bottles of sand and fifteen bottles of mud were set up, each with one Mangrove propagule (controls). Treatment one was set up as previously stated (N=15 for sand and mud respectively), except fiddler crabs were placed within each bottle.
Are Fiddler Crabs a Keystone Species In Local Mangrove Forests?
Hypothesis: Fiddler crabs will increase productivity and growth or red mangroves
Rationale: The presence of fiddler crabs would help to oxidize the soil through borrowing activity and metabolic wastes from the fiddler crabs would provide additional nutrients for growth
