I invite colleagues to open debate around the issues raised in my presentation, both those relating to research and to practice.

Thank you very much Ricarda for your interesting presentation on this unusual and very beautiful habitat. Given that the bedrock is argillite, are the soils fairly acidic? I know of similar flat openings in the forest where the bedrock is exposed in the Southeastern US (call 'glades'), but these are generally limestone. Do you know of similar habitats to the bedrock meadows elsewhere in the world? Also, what is 'crispness analysis'?
I would love to take a field excursion to bedrock meadows one day?

Dear Susan, thanks for visiting my talk and for your interest in Bedrock Meadows. I am just wrapping up a manuscript on the findings I presented in my talk. Next step will be having a closer look into the Bedrock Meadow vascular and non-vascular plant-community patterns and underlying soil characteristics. So we will hopefully be soon able to answer your question on soil pH.
Next to partial similarities to the Meadows on Vancouver Island and Timberline meadows (described by Wagner et al 2004), I am not aware of similar habitats, but I woud be happy to get hints and ideas where to look for them! Given that Bedrock Meadows might be (partially) also a result of indigeneos land-use (inluding intentional burning and facilitation of bulbous/edible/usable plants, Bedrock Meadows it might be hard finding similar habitats....but I am open for suggestions and new things to learn!
Regarding crispness analysis, it tells you something about the optimal number of clusters based on the "power of separation" or better to say on values telling you how good one plot fits into the cluster where it is allocated to. Calculating mean crispness values for clusters is an integrated function in JUICE based on Botta-Dukat et al 2005.
Thanks again and have a wonderfull day, Ricarda

Thank you for your fast answer Ricarda. I would be interested in getting a copy of publications -- when you have them -- about these bedrock meadows.
Best wishes,
Susan
