Harmful Algal Species (HAS) and Harmful Algal Blooms (HABs)

Ciano-HABs in laghi artificiali del Mediterraneo (Sardegna; Lago Bidighinzu, a sinistra; Lago Posada, a destra). L’accumulo di cellule cianobatteriche lungo le sponde, soprattutto a causa dell’azione dei venti, provoca l’intensa colorazione blu-verde dell’acqua (da Sini P., Dang T.B.C., Fais M., Galioto M., Padedda B.M., Lugliè A., Iaccarino C., Crosio C., 2021.

The study of potentially Harmful Algal Species (HAS) is a central focus of the ecology group's research. The proliferation of these species causes Harmful Algal Blooms (HABs)—events capable of triggering direct consequences for aquatic communities (e.g., extensive animal die-offs) and altering ecosystem structures, functions, goods, and services. These consequences also impact human health, such as through the transmission of biotoxins via the food web. The importance of this research is closely tied to the immediate impact new knowledge can have on various sectors, ranging from the management of environmental and natural resources to socio-economic and health aspects.
