Those will be the sort of plants hardest hit by climate change...little chance for them to move...

Certainly specialists will tend to be hit by climate change, and many have already been hit hard by habitat destruction. On the other hand some of these ferns are pretty good dispersers via spores, and therefore seem good at 'finding' suitable habitat. Species with poor dispersal mechanisms (e.g. ant dispersed seed that rarely moves between populations) seem very vulnerable.
On a side note, it has just occurred to me that although I have seen thousands of A. ruta-muraria growing in walls around the place, I don't think I have ever seen it in the wild! Presumably it likes limestone rock crevices..?

It is common where I live both oin walls and in crevices (in limestone).

I tend to agree more with Tristan's line of thought Cohan. Species with a 'healthy' propagation via seeds/spores are/will be the least affected. Then, from what I've seen both in North America and Europe, destruction/loss of habitat due to human activity is one of the biggest threats for species conservation (which A. rhizophyllum is not anyway).

A. ruta-muraria can also be common in various localities of Carpathian Mts - yes, limestone crevices; including in walls of nearby houses. Here's a picture I had handy from last year.
