摘要

本文对菲律宾莱特岛卡里加拉湾沿岸的红树林(树木和棕榈)进行了详细的生态调查,比较了不同森林类型(沿河和边缘)和区域(向陆、向中和向海/沿水)的多样性、植被结构、物种组成和指示物种,并研究了它们与环境变量的关系。共记录了隶属于 12 个科的 22 种红树林物种,其中数量最多的是白松属(Sonneratia alba),其次是红叶榕属(Nypa fruticans),然后是红豆杉属(Avicennia rumphiana)。研究发现,河岸红树林的多样性(香农-维纳)(0.94 ± 0.07;1.20 ± 0.04)明显高于中游和下游/沿岸的边缘红树林(p < 0.001)。在边缘红树林中,红树林物种 Aegiceras corniculatum 与中向区有关,Camptostemon philippinensis、Aegiceras floridum、Rhizophora mucronata、Sonneratia alba、而边缘地带的向陆区和沿河的所有区域一般都与耐盐性从低到最佳的物种有关,如 Nypa fruticans 和 Avicennia rumphiana 的数量最多。此外,共有 14 种红树林被确定为指示物种。最后,根据解释红树林分布的环境因素,红树林物种一般可分为沿河红树林和边缘红树林,研究发现,土壤孔隙度、含水量、土壤盐度以及与海洋或河流边缘的距离是决定多样性模式的最重要环境因素。

Diversity and assemblage of mangroves along the carigara bay in Leyte, Philippines

Diversity and assemblage of mangroves along the carigara bay in Leyte, Philippines

The paper presents a detailed ecological investigation of mangroves (trees and palm) along Carigara Bay in Leyte, Philippines by comparing the diversity, vegetation structure, species composition, and indicator species among forest types (riverine and fringe) and zones (landward, middleward, and seaward/along water) as well as by examining their relationships with environmental variables. A total of 22 mangrove species, belonging to 12 families were documented wherein the most abundant was Sonneratia alba, followed by Nypa fruticans, then by Avicennia rumphiana. It was found that the diversity (Shannon-Wiener) of riverine mangroves (0.94 ± 0.07; 1.20 ± 0.04) was significantly higher than the fringe at the middleward and seaward/along the water (< 0.001). In the fringe mangrove forests, the mangrove species Aegiceras corniculatum was associated with the middleward zone, and Camptostemon philippinensis, Aegiceras floridum, Rhizophora mucronata, Sonneratia alba, and Lumnitzera littorea were associated with the seaward zone, whereas landward zone of fringe and all the zones in riverine were generally associated by species with low to optimum salt tolerances such as Nypa fruticans, and Avicennia rumphiana as the most abundant. As well, a total of 14 mangroves have been identified as indicator species. Lastly, mangrove species can be generally classified as riverine and fringing based on the environmental factors explaining their distributions, and it has been found that soil porosity, water content, soil salinity, and distance from the sea or river’s edge were the most significant environmental factors that determine diversity patterns.
