Diversity and Distribution of Characeae in the Maghreb (Algeria, Morocco, Tunisia)
International audience Characeae are macroscopic green algae present in the Maghreb (Morocco, Algeria, Tunisia) that are known since the 19th century works of Desfontaines (1800) and Braun (1868). Feldmann (1946) published the first regional synthesis, and this study provides a new Maghreb-wide synt...
