Dera list members,

I am trying to estimate species richness for several single sites and for
the collection of all sites.  I am looking at the specpool and estimateR at
the vegan package.

Is there any other alternatives in R?

How these estimates are influenced by diffrent sampling effort at each site
(i.e., the number of visits to the sites varies)?

I am trying to get also an estimate of the detection probability, but it
seems that this parameter is not included in those functions.

Best,

Manuel
