Question

In Caribbean seagrass meadows manatee grass Syringodium filiforme appears before turtle grass Thalassia testudinum. (a) Describe the design of an experiment to determine the mechanism of this successional sequence. (b) Give the statistical null hypothesis for this experiment.

Answer 1

ANSWER::

The fact that the manatee grass appears before turtle grass, suggests that turtle grass needs something from the manatee grass, to develop. This is called a secondary succession when an organism needs the presence of another, either dead or alive, to develop.

To know how this works you could first establish several zones, one where manatee grass has never been, another where manatee grass was but got removed, another where manatee grass was but got removed along whit the substrate and another were manatee grass is.

If in the first one turtle grass develops then it does not need manatee grass if in the second turtle grass needs the decayed material of manatee grass if the third turtle grass needs only the modifications on the soil exerted by manatee grass and if in the forth turtle grass needs the live presence of manatee grass.

So our null hypothesis could be Ho = if manatee grass has no influence in the development of turtle grass, turtle grass will grow in an area where manatee grass has never been.
