Aquatic Botany and Ecology

The laboratory is focused on the study of trophy, macrophytes and the ecological status of aquatic environments with particular reference to transitional and coastal environments. The main activities concern:

  • The analysis of environmental parameters and nutrient concentrations in the water column, sediments, particulates and biota;
  • Determination of sedimentation rates and particulate dispersion; Primary determination of aquatic macroalgae and aquatic angiosperms and their correlations with environmental parameters;
  • The taxonomic determination of macroalgae and aquatic angiosperms using both traditional methods with microscopic and genetic determination by applying DNA barcoding techniques;
  • The determination of the ecological status through indices based on the presence and type of macrophytes such as MaQI;
  • The extraction of food compounds (Carbohydrates, Proteins, Lipids) and cosmetics (Agar, Antioxidants, etc.) from macrophytes and the use of various types of algal extracts for their application in the antiparasitic and anticancer fields.

The various activities also make it possible to make mass balances of single elements or compounds and to use the skills acquired for the environmental recovery of degraded environments through aquatic angiosperm transplants.
