Simberloff and Wilson original defaunation experiment data
Description
A list of datasets containing the presence-absence data gathered originally by Simberloff and Wilson in their defaunation experiment of six mangrove islands in the Florida Keys.
Format
A list with 6 dataframes, each corresponding to the survey of a different island. Dataframes have in columns:
- Taxa
Taxa considered
- PRE
Presence-absence before the defaunation process
- Integers (e.g. 21, 40, 58...)
Several columns with presence-absence data for the day specified
- Tax. Unit 1
Highest taxonomical unit considered
- Tax. Unit 2
Second highest taxonomical unit considered
- Genera
Genera of the identified taxon
- Island
Island of identification of the taxon
Details
The defaunation experiment of Simberloff and Wilson was aimed to test experimentally the Theory of Island Biogeography. The approach sought was eliminating the fauna of several islands and following the recolonization proccess.
After some trials, six red mangrove islets of Florida Bay were chosen for the task. These islets had to be stripped of all arthropofauna without harming the vegetation and then all the colonists were identified. The result of these defaunation experiments supported the existence of species equilibria and were consistent with the basic MacArthur-Wilson equilibrium model.
Note
The shaded entries in the original dataset, for taxa inferred to be present from other evidence rather than direct observation, are considered as present in these datasets.
