Introduction: α-amylase is a major form of amylase found in humans and other mammals. It is the special key enzyme involved in carbohydrates breakdown. Inhibition of this enzyme could be used in treatment of diabetes. In this study, the effect of ten Iranian macrolichens on alpha amylase were tested. Methods: Different concentrations of the extracts (25, 50 and 75 mg/ml) were incubated wi...

Compared to the mainland, boreal oceanic islands would be expected to have a depauperate lichen biota because of their isolation, small area, exposure to salt spray and structurally simple habitats. We surveyed the macrolichens (non-crustose lichens) and quantified habitat associations on Kent Island, an 80-hectare island that lies at the mouth of the Bay of Fundy, New Brunswick, Canada. A tota...
