“…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.…”

M ANGROVE habitats are important ecosystems for their ecological value, and goods and services they offer. These costal habitats are currently vulnerable due to excessive human activities. The black mangrove Avicennia marina (Forssk.) Vierh. (Avicenniaceae) populations growing in Nabq protected area represents the northernmost latitudinal limit of the Indo-Pacific-East African naturally growing mangrove forests. In this study, nine A. marina populations inhabiting Gulf of Aqaba were studied to assess the genetic relationship among the populations by Start Codon Targeted (SCoT) and Inter Simple Sequence Repeat (ISSR) as DNA Markers. Variations of photosynthetic pigment content were assessed in the populations growing in different habitat types. The numbers of polymorphic bands were 18 and 6 for SCoT and ISSR, respectively. The percentage of polymorphism showed wide range amounted 40.9 for SCoT and 25 for ISSR, while the number of amplicon bands ranged from 8-10 in SCoT and 2-9 in ISSR. The genetic relationships among populations using SCoT and ISSR analysis showed close relationship between the nearby but different habitat type populations such as sand mound and littoral populations, or between populations of same habitat types in the study region. The photosynthetic pigment content of chlorophyll a and b, and carotenoids in the littoral and intertidal populations were higher than that in the sand mound and salt plain populations. Populations inhabiting Nabq protected area have wide range of polymorphism among different habitat types. Further studies are required to investigate the genetic relationships among populations of A. marina inhabiting the eastern and western sides of the Red Sea.
