Rivers in the Eastern Mediterranean‎,‎ Israel in particular‎,‎ are small and located mostly in the coastal plane‎.‎ In the first step of ecosystem assessment‎,‎ 671 species of algae and cyanobacteria belonging to nine taxonomic divisions were revealed by our research during 2002‎-2009 in the Yarqon‎,‎ Alexander‎,‎ Hadera‎,‎ Qishon‎,‎ and Oren rivers in the coastal plane‎,‎ the Lower and Upper Jordan Rivers in the rift valley‎,‎ as well as the Zin stream in the Negev Desert‎.‎ This book presents and discusses research which suggests that in semiarid environments the influence of anthropogenic factors is strongly modulated by climatic impacts causing a marked decrease of species richness in aquatic ecosystems from north to south‎.‎
