The development of the karst phenomenon is usually related to the presence of rocks with high solubility in water. However, even if the most studied karst circuits are developed in carbonate rocks (e.g., limestones and dolomite), important karst morphologies can also be recognized in sandstones or evaporite terrains (e.g., salt …

Probably gypsophytes are the most interesting set of edaphic specialists of arid and semiarid climates. Despite they conform a global biodiversity priority, there are almost no information about those adaptive traits that confer such a specialised behaviour. Our broad hypothesis is that gypsophytes are "refuge-endemics" that are able to grow on gypsum …
