“…In general, the growth of A. marina populations ranges from small shrubs in dry habitats to large trees [up to 40m] in humid tropical ecosystems (Duke et al, 1998;Tomlinson, 2016). Moreover, the phenotypic variation in different populations is depending on the mutual action of the environment and the genotype (Peloso et al, 2017;Santos et al, 2024). Four main habitat types are inhabited by A. marina populations along the South Sinai coast, sea-side habitats are the intertidal and shoreline while, salt plains and sand mounds are landward (Hegazy, 1998;Mashaly et al, 2016), characterized by different environmental factors.…”
