Distributionand Diversity of Macro Algae Communities in the Ambon Bay

Abstract

Water conditions affected by natural and anthropogenic parameters such as sedimentation and solid waste disposal can influence the growth and distribution of macro algae. Sustainable management efforts can reduce damage on the Gulf coast of Ambon due to human activities and land clearing. This study was conducted in October 2008 using the transect method with 3 replicates in five locations i.e., Tantui, Air Salobar, Hative Besar, Halong, and Lateri. The interior and exterior waters of Ambon Bay contained different habitat conditions due to sedimentation processes. The purpose of this study was to determine the distribution and diversity of macro algae communities in the Ambon Bay. The results found 21 species of macro- algae consisting of 10 species of Rhodhophyceae, 6 species of Chlorophyceae, and 5 species of Phaeophyceae. The highest density value of seaweed in Tantui was 389.0 g/m² of Chlorophyceae of Halimeda genus. In Air Salobar and Halong, the highest density value was Rhodophyceae of Gracilaria genus of 172.0 g/m² and 155.0 g/m², respectively. For the other genus in the Tantui and Lateri regions were dominated by Ulva at 92.10 gr/m2 and Padina of 20.0 gr/m2, respectively. The highest dominance of macro algae in the Hative Besar was found Chlorophyceae of Halimeda genus of 2.93 %, in the Air Salobar of Phaeophyceae of Turbinaria genus of 1.43 %. The difference values in density and the dominance of macro algae indicated an influence of habitat and environment due to seasons, sediment, and solid waste disposal to the diversity of macro algae.

Diversity, Abundance, and Distribution of Macroalgae in Coastal Ecotourism Areas — A Case Study at Baluran National Park, Situbondo, Indonesia

“…Furthermore, the evenness index for Station I in the medium category was 0.54, and the low category in Station II was 0.37 (Figure 5). One of the factors that influence the growth of macroalgae is the water flow and type of substrate, where both factors determine the form of the holdfast; it occurs due to the process of macroalgae adaptation to the environment (Eriksson & Bergström, 2005;Jamilatun et al, 2020;Litaay, 2014). Although the type of substrate determines the variation of macro types of algae that grow, the same type of substrate tends to have the same diversity (Herlinawati et al, 2017).…”

Komposisi jenis dan Pola Sebaran Makro Alga di Pantai Passo Larier Teluk Baguala Pulau Ambon

“…Sebaran makro alga dapat dibagi berdasarkan kedalaman yaitu pada perairan dangkal yang didominasi oleh spesies makro alga hijau dan spesies makro alga coklat sedangkan yang sering ditemukan pada perairan yang lebih dalam adalah spesies makro alga merah. Sebaran spesies makro alga sangat dipengaruhi oleh faktor lingkungan dan habitat (Litaay, 2014), melalui sebaran dapat diketahui daerah yang menjadi tempat hidup dan bagaimana cara makro alga hidup di tempat tersebut, dan apabila faktor lingkungan dan habitatnya baik, maka distribusi jenis makro alga juga akan baik. Makro alga biasanya tumbuh mengelompok dengan berbagai jenis makro alga lainnya.…”

Evaluation of the Quality of Coastal Ecosystems in the Spermonde Archipelago Using Macroalgae as Indicators

“…The coastal city of Makassar has several functions including for the port of Pelni ships, inter-island traditional vessels, fisheries, sea transportation routes, and tourist attractions. These activities cause changes in land use and contribute for nutrients and other toxic wastes to the water; thus, eutrophication often occurs [4,5]. This can trigger an increase in biomass as well as degradation and death of marine producers such as macroalgae thus can threaten the lives of another marine biota.…”
