Analysis of the Population Structure and Dynamic of Endemic Salvia ceratophylloides Ard. (Lamiaceae)

Understanding how changes of any origin interact with the structure and survival entire populations is very important for protection conservation threatened, rare and/or endemic species. In this study, population dynamics Salvia ceratophylloides Ard., a precious species, belonging to subgenus Sclarea (Moench) Benth., section Plethiosphace Benth. (Lamiaceae) exclusive suburban environments Reggio Calabria (Southern Italy), was analysed. Interactions between species its different growth habitats were examined. Moreover, disturbance factors which directly affect demographic viability influencing growth, reproduction distribution in area identified. From 2019 2021, census by counting individuals all known stations, recorded according specific protocol, carried out. The data statistically analysed compared those phytosociological surveys out using Braun-Blanquet method summarised classes, accordance hierarchical floristic classification system vascular plant communities, accepted at national European levels. also related threat that afflict S. ceratophylloides.
