Kevin R Burgio

Levan,

Seems like I am bumping into you quite a bit! Here is a link to Rob Colwell's software: http://viceroy.eeb.uconn.edu/RangeModel/

And here is the citation / paper for how it works: Colwell, R.K. (2008) RangeModel: tools for exploring and assessing geometric constraints on species richness (the

mid-domain effect) along transects. Ecography, 31, 4–7.

Levan Mumladze

Thanks Kevin:)))

I just asked for R package.

Nachiket Kelkar

Hi Levan,

There is a recent package in R: package 'rangemodelR v0.1'.

URL: https://cran.r-project.org/web/packages/rangemodelR/index.html

Would recommend you to try this one.

Thanks,

Nachiket

Great, finally it appeared in R :))

Omar Rojas-Padilla

The package was removed from CRAN; You know of any new?

Could it be that this alternative is still valid?: http://viceroy.eeb.uconn.edu/RangeModel/index.html

The alternative (Colwells software) is valid and primary source for MDE simulation

Miguel Barbosa

Hi all, I am preparing a lecture on marine diversity and would like to explain the mid-domain effect using some sort of practical game. Anyone knows if there is a way to explain the effect of geographical constrains in producing overlapping species range and thus creating a peak of sp richness towards the center of the distribution?

Thanks for all the suggestions

Miguel

I think the seminal paper of Colwell and Lees (2000) ( http://viceroy.eeb.uconn.edu/RKCPublications/ColwellAndLees2000a.pdf ) is the best to show the role of geometric constraints in producing mid-peak.

thanks for the paper. It is extremely helpful. However, I am interested in creating a more interactive way to illustrate the MDE. I have read somewhere that you can use a box and pencils of different colours to represent different sp ranges and throw them randomly into the box. The prediction is that the average range of colour pencils will be concentrated in the centre of the box... Not sure if this works tough! Anyway, thanks for the paper.
