Re: NANFA-- More on Species-Area Relations (SARs)

I have a question I would like to ask the group about species and niches.
Basically what I have on my mind is this, In any given habitat is species
diversity limited by ecological niches or by the ability of the genera that
lives there to adapt to available niches? Or is the number of occupied niches
a factor of time between catastrophic events that wipe the slate clean or at
least cut down on species? I ask this because of the differences in fish
populations in different areas of the globe. It seems that in some areas
niches are filled that are blank in other areas. Any one have comments on
