AdaptationsAdaptations
Anoxia- prop up absorb oxygen through lenticels (pores)
High Salinity-90% salt excluded, salt taken in stored in vacuoles then exuded through leaves
Water Loss-restricting stomata on leaves

HypothesisHypothesis
EDITED: If two Red Mangroves are placed in different systems the propagules will grow at different rates.
If the mangrove propagules are placed in a hospitable system under the right conditions, they will mature and grow into adulthood.

ConclusionsConclusions
Established Mangroves experienced more growth than the propagules.
Hypothesis-supported each propagule matured and grew
Propagules hit growth spurt at the same time during development.
Loss and addition of leaves by propagules.

Future SuggestionsFuture Suggestions
Introduce a species found in Mangrove Swamps to the tank.
Get a taller light for Mangrove C. Try out another species of mangrove
alongside a red mangrove propagule.
