ecospat.niche.overlap

[Arta]

Dear all,

I want to perform niche overlap based on Broennimann 2012 using ecospat function in R. I read the literature about this approach. 

I found that I should Create a grid with occurrence densities along one or two gridded environmental gradients using ecospat.grid.clim.dyn.

But I don't know how to use the output of two species modeling (maxent) here,  As I am new in R. 

Any comment would be appreciated.

Many  thanks

The Ecospat tests don't actually use Maxent models; they use kernel density estimates of species distributions and available environments instead.

Dear Dan;

Thanks for your prompt reply.

I've estimated environmental niche overlap of two groups by means of ENMtools.pl.

I found that the R script is available now. Is there any advantage in using R script?

Many thanks

The R version does a whole bunch of things that the standalone version doesn't do.  A lot of that is brand new and hasn't been previously available anywhere else.  There are details about most of it on the Species in Space blog, and also in the vignette on the github page.  The standalone version of ENMTools is no longer being updated, so if you want to keep up with the cool new stuff that is coming out, you should definitely check out the R package.
