Hyper-oceanic liverwort species of conservation concern: Evidence for dispersal limitation and identification of suitable uncolonised regions

In order to successfully manage and conserve species and plant communities, it is important to have a good understanding of their ecology and distributions. The three liverwort species Anastrophyllum donnianum, Scapania ornithopodioides and Scapania nimbosa, are restricted to the mixed northern hepa...

The three liverwort species Anastrophyllum donnianum, Scapania ornithopodioides and Scapania nimbosa, are restricted to the mixed northern hepatic mat community found in the most oceanic parts of north-western Europe.

Maximum entropy (MaxEnt) models were developed for each species using target-group background data, and five environmental coverage layers. Our results indicate that all three species are limited by dispersal rather than the availability of suitable areas in Norway. In particular, A. donnianum seems to be limited from reaching uncolonised highly suitable areas in northern Norway due to a barrier unsuitable region with insufficient summer rain.
