“…The hypothesis proposed by Kendrick et al. (2012) may thus apply to some seagrass species, particularly short‐lived species producing a large number of seeds (Phan, De Raeymaeker, Luong, & Triest, 2017), especially if one also accounts for the dispersal of vegetative fragments (McMahon et al., 2014). However, the prevalence of clonality is associated with a decrease in the loss of diversity due to the influence of drift (Reichel et al., 2016), which may partly explain the elevated levels of genetic diversity observed in well‐established meadows.…”

“…Our results of significant SGS both at ramet and genet levels, especially in short distance classes, indicate that gene dispersal was spatially restricted. The genet-level SGS of H. ovalis was similar to other seagrasses such as Posidonia oceanica (Diaz-Almela et al, 2007), Zostera marina (Becheler et al, 2010), Halophila beccarii (Phan et al, 2017), and Cymodocea nodosa in Italy (Ruggiero et al, 2005b), but weaker than that of Cymodocea nodosa in Spain (Alberto et al, 2005). The contribution of seed dispersal to SGS is likely to be higher in H. ovalis than other seagrasses, given that the rate of horizontal rhizome elongation is very high in H. ovalis (Marbà and Duarte, 1998).…”

“…A more detailed study covering the sampling of this species from the entire coast of India is necessary to understand the genetic variation of H. beccarii, as local environmental variables determine both phenotypic plasticity and genetic response of seagrass (Nguyen et al, 2015;King et al, 2018). Supporting this evidence is a recent study on karyomorphological properties of H. beccarii from the coast of Thailand, that revealed in difference of H. beccarii karyomorphological properties from India and China (Hang Phan et al, 2017).…”

“…Except the Indian coast, they also have a wide distribution in South-East Asia (Short et al, 2011) including their presence from the coast of Sri Lanka (Udagedra et al, 2017), Bangladesh (Abu Hena and Short, 2009;Masum Billah et al, 2016), Malaysia (Zakaria et al, 2002;Fakhrulddin et al, 2013), Philippines (Liao andGeraldino., 2020), Thailand (Aye et al, 2014;Hiranphan et al, 2020) and Viet Nam (Hang Phan et al, 2017). H. beccarii acts as one of the pioneer species in the ecological succession process leading to mangrove formation of the Indian coast (Jagtap, 1985;Untawale and Jagtap, 1991;Parthasarathy et al, 1988Parthasarathy et al, , 1991.…”
