Coastal Landform Constrains Dispersal in Mangroves

Mangrove forests are dynamic ecosystems found along low-lying coastal plains tropical, subtropical, and some warm-temperate coasts, predominantly on tidal flats fringing deltas, estuaries, bays, oceanic atolls. These landforms present varied hydrodynamic geomorphological settings for mangroves to persist could influence the extent of within-site propagule transport subsequent local regeneration. In this study, we examined how different landform characteristics may genetic diversity, kinship, neighborhood structure mangrove populations. To do so, considered independent populations Avicennia marina , one most abundant widespread species, located in estuarine bay environments spread across Western Indian Ocean region. A transect approach was estimate kinship-based fine-scale spatial using 15 polymorphic microsatellite markers 475 adult A. trees from 14 Elevated kinship values significant up 30, 60, or 90 m distances were detected sheltered systems void river discharge, suggesting a setting suitable very retention establishment within neighborhood. Slopes linear regression over restricted distance 150 significantly declining each transect. Contrastingly, such has not been transects bordering rivers considered, alongside partially creeks, that recruitment here is governed by unrelated carried-away mixed-origin propagules. South African showed strong inbreeding levels. general, have shown can locally experience modes movement, explained their position landforms. Thus, resilience through natural regeneration achieved responses characterized conditions, which be important information management protection variety environments.
