Checklist of the marine macroalgae of Vietnam

Abstract

Despite a rich seaweed flora, information about Vietnamese seaweeds is scattered throughout a large number of often regional publications and, hence, difficult to access. This paper presents an up-to-date checklist of the marine macroalgae of Vietnam, compiled by means of an exhaustive bibliographical search and revision of taxon names. A total of 827 species are reported, of which the Rhodophyta show the highest species number (412 species), followed by the Chlorophyta (180 species), Phaeophyceae (147 species) and Cyanobacteria (88 species). This species richness is comparable to that of the Philippines and considerably higher than Taiwan, Thailand or Malaysia, which indicates that Vietnam possibly represents a diversity hotspot for macroalgae. A comparison of the species composition with neighbouring countries yielded surprisingly low similarities. Rather than an indication of a biogeographical pattern, we are of the opinion that the low similarity with neighbouring countries is primarily an artifact resulting from taxonomic inconsistencies. The checklist presented here could serve as a valuable tool to reveal the seaweed diversity in Vietnam and to stimulate intraregional comparative research.

Characterizing the Three Different Alginate Type of Sargassum siliquosum

“…The key of phaenotypic characters of brown algae was determined by the main axis, vesicle, receptacle, and thallus (Nguyen, 2015).Sargassum genus from Phaeophyta is one of the largest species all over the world (Nguyen et al, 2013). Consequently, this species is ecologically important in the marine ecosystem including Indonesia.…”

Structure and regeneration status of mangrove patches along the estuarine and coastal stretches of Kerala, India

“…As the current study was designed to provide the structural characteristics of tree mangrove species, the mangrove associate, Acrostichum species were excluded; L. racemosa and E. agallocha, which had a very restricted distribution in Kerala, were not found in this study. The reduction in species number could be attributed to the intensity of research efforts, sampling locations, and species considerations (Van Nguyen et al 2013;Whitmore 1988). …”

Can Seaweed Farming in the Tropics Contribute to Climate Change Through Emission of Short-Lived Halocarbons?

“…Updated records for Malaysia give a total of 355 taxa belonging to the Cyanophyta (8 taxa), Chlorophyta (87), Rhodophyta (156) and the Phaeophyta (90) (Phang 2015 unpublished data). A total of 827 species comprising 180 Chlorophyta, 147 Phaeophyta, 412 Rhodophyta and 88 Cyanophyta were compiled from various published sources for Vietnam (Nguyen et al, 2013). In general the red seaweeds dominate in terms of diversity followed by the brown and green seaweeds.…”
