Roger,
Is it possible w e are confusing two variables here? Variability in the
environment and isolation of the environment from others.
Galapagos Islands have both a high level of endemicity and many missing taxa,
no? So, Madagascar is just a rather extreme example of island geography?

Apparently a generalization that fits some of the facts.
The communities of Madagascar are characterized by high
levels of endemicity, great species diversity in some taxonomic
groups, and a complete absence of others.
