Microsatellite data of 14 Avicennia marina populations from Mozambique Channel area

Mangrove forests are dynamic ecosystems found along sheltered low-lying coastal plains in warm-temperate, tropical and subtropical regions, predominantly on tidal flats, deltas, estuaries, bays, but also on oceanic atolls. These landforms present varied hydrodynamic and geomorphological settings for mangroves to establish and could influence the extent of propagule transport and subsequent regeneration. In this study, we examined whether these landform characteristics influence the genetic diversity and structure of Avicennia marina, one of the most abundant and widespread mangrove species. To do so, we considered 14 populations located in estuarine and coastal bay environments spread across the Western Indian Ocean region. A transect approach was considered to estimate kinship-based fine-scale spatial genetic structure using fifteen polymorphic microsatellite markers in 475 adult A. marina trees from 14 different populations. No overall significant difference was found in the levels of...红树林是一类动态生态系统，分布于暖温带、热带及亚热带地区受庇护的低洼沿海平原，主要见于潮滩、三角洲、河口、海湾，亦可分布于大洋环礁。此类地貌为红树林的定植提供了多样的水动力与地貌学环境，同时可影响繁殖体的传播范围及后续更新过程。本研究旨在探究上述地貌特征是否会影响白骨壤（Avicennia marina）的遗传多样性与群体遗传结构——白骨壤是分布最广泛、丰度最高的红树林物种之一。为此，我们选取了西印度洋区域内河口与沿海海湾生境中的14个种群作为研究对象。我们采用样带法（transect approach），借助15个多态性微卫星标记（polymorphic microsatellite markers），对来自14个种群的475株成年白骨壤进行分析，以估算基于亲缘关系的精细空间遗传结构。本研究未在相关指标水平上检测到整体显著差异……
