Abstract

Extreme environmental gradients generate distinct patterns in species distributions dependent on their stress tolerance and competitive capability. This is the situation along the steep land-water gradient in a stone quarry on Öland's alvar. Availability of water and nutrients varies profoundly between bare limestone slabs with no soil, via temporary to permanent ponds with thick sediments. Only a few, extremely robust species of plants (Sedum album and S. acre), colonial cyanobacteria (Nostoc commune) and mosses (Syntrichia ruralis and Racomitrium canescens) survive on the bare limestone slabs experiencing prolonged summer drought and winter flooding. Nostoc commune can survive drought for many months and resume photosynthesis and efficient HCO ^3" utilization within minutes after water has become available.
