Phytoecology, dynamics and pollen reconstitution of two raised bogs (Aoural and Ain Salhat) of little eastern Kabylia: case of the Oued Zhor watershed (North-East Algeria). — Two raised bogs, Aoural and Ain Salhat, located in the region of the little Kabylia (North East of Algeria), were reviewed in both floristic inventories and pollen analyses during six years (2016-2022). The floristic study has revealed the existence of 174 taxa, 119 for the Aoural pond and 109 for the Ain Salhat one. Analysis of surface sediments pollen from the two ponds allowed us to identify 52 pollen taxa. In Ain Salhat pond, tree taxa dominate this assemblage, reaching a rate of 47.4%, followed by herbaceous ones with 24.5%, shrubby taxa with 24.4% and finally undetermined taxa with 3.7%, this is due to the position of the pond which is situated in a wooded forest environment. On the other hand, in Aoural’s pond, herbaceous taxa dominate spectra with 37%, followed by trees ones which account for 36%, shrubs (23.4%) and finally undetermined taxa with at around 3.6%. The contribution of pollen analysis to the knowledge of the current flora of the two studied ponds is of 58%. In total, 186 species have been identified using these two methods, of which 12 species have only been observed in the pollen spectrum. Floristic study and pollen analysis are therefore two complementary methods of study. [ABSTRACT FROM AUTHOR] |
