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.

Keywords: Chlorophyta; Cyanobacteria; marine floristics; Phaeophyceae; Rhodophyta; South China Sea; Vietnam; Western Pacific Ocean

Introduction

Vietnam has a coastline of approximately 3260 km in length, dotted by numerous islands, islets, atolls and reefs in approximately 1,000,000 sq km of sea area. The primarily north-south orientation of the coastline spans two climatic zones with a subtropical climate at higher latitudes and a tropical climate in the south. A diverse variety of ecosystems, ranging from extensive lagoons and mangroves to rocky shores and coral reefs, provide suitable habitats for luxuriant seaweed growth. Marine macroalgae play an important role in the everyday lives of the people of Vietnam. Several species are used as food (humans and livestock), for the extraction of agar and carrageenan, in traditional medicine or as biofertilizer (Huynh and Nguyen H. Dinh 1998, Dang et al. 2007). Yet knowledge of the marine seaweed diversity of Vietnam is scattered in the literature and largely inaccessible to phycologists as most data are published in regional papers, book chapters or reports and often in Vietnamese.

The history of seaweed exploration in Vietnam dates back to 1790, when the Portuguese Jesuit missionary and botanist João de Loureiro reported the names of 11 marine macroalgal species from Vietnam in his Flora Cochinchinensis. In the 19th century, several researchers such as J. Agardh (1848, 1851–1863) and De Toni (1895, 1900, 1905) included Loureiro’s records in their publications, but Vietnamese macroalgal diversity remained largely unexplored. This changed in 1954, when Dawson (1954) published the very first checklist on the Vietnamese marine flora of Nha Trang Bay in the province of Khanh Hoa. Dawson reported a total of 204 species, nearly all of which were new species records for Vietnam (16 Cyanobacteria, 118 Rhodophyta, 22 Phaeophyceae and 48 Chlorophyta). His checklist represents the first report in English on the marine flora of an Asian locality. Since that time, Vietnamese phycologists have developed a clearer picture of Vietnamese seaweed flora (Pham H.H. 1969, 1985, Nguyen H. Dinh 1980, Nguyen H. Dinh et al. 1993, Nguyen H. Dai 1997, 1999, 2007, Nguyen H. Dai et al. 2000, Nguyen H. Dai and Pham H.T. 2001, 2002, 2003, Nguyen H. Dai and Le N.H. 2005, Le N.H. 2000, 2001, 2004, Le N.H. and Nguyen H. Dai 2006, Dam and Nguyen V. Tien 1996, Dam 2003, 2007, Nguyen V. Tien 1996, 2007, Pham H.T. 1996, 1999). The reports of Pham H.H. (1969) and Nguyen H. Dinh et al. (1993) in particular have contributed greatly to knowledge of the macroalgal flora along the north and the south coasts of Vietnam, respectively. Unfortunately, these lists were published in Vietnamese, and the information remained largely inaccessible to the international community.

Funding provided by the California Sea Grant College Program and several expeditions to the offshore islands of the Spratly (Truong Sa) archipelago (Dam and Nguyen V. Tien 1996, Nguyen H. Dai 1999, Pham H.T. 1999, Nguyen H. Dai and Pham H.T. 2001, Nguyen H. Dai et al. 2009) boosted diversity-oriented research on Vietnamese seaweeds in the 1990s. Even though the diversity of some macroalgal genera was explored in depth in a few publications, e.g., Gracilaria and Graciliaropsis (Nguyen H. Dinh 1992, Ohno et al. 1999, Le N.H. and Nguyen H. Dai 2010), Eucheuma and Kappaphycus (Nguyen H. Dinh and Huynh 1995), Sargassaceae (Nguyen H. Dai 1997, 2007) and Chlorophyta (Nguyen V. Tien 2007), no new attempt was made to bundle all the data on Vietnamese macroalgal diversity into a comprehensive list accessible to the world scientific community. The aim of this publication is to compile all of this information into a checklist of the marine algae of Vietnam.

Materials and methods

Geographical scope

The Vietnamese coastline (excluding islands) is appoximately 3260 km long, stretching from Mong Cai in the north to Ha Tien in the south. The coastline is bordered on the northeast by the Gulf of Tonkin, on the east by the South China Sea and on the southwest by the Gulf of Thailand. The coast is physically very heterogeneous, harbouring extensive lagoons and estuaries (e.g., the Mekong Delta), as well as rocky shores with extensive coral reefs and seagrass beds. In addition to the mainland coastline, the South China Sea contains thousands of islets scattered midway between the Philippines and the Vietnamese mainland coast. Although claimed by several countries, the checklist includes algal records of the Paracel (Chinese: Xisha Islands; Vietnamese: Hoang Sa) as well as the Spratly Islands (Vietnamese: Truong Sa).

The checklist is based on an exhaustive bibliographical search. Both local reports and scientific publications were screened for species records, and the species were recorded in a database. Species are ordered alphabetically grouped as follows: Cyanobacteria, Rhodophyta, Chlorophyta and Phaeophyceae. All taxon names were revised to employ currently accepted species names following Algaebase (Guiry and Guiry 2012). References to the original publications are indicated in square brackets, and taxonomic synonyms and their references are included within round brackets. Data are presented as follows: Current name Author [Reference #(Reference of synonym, Synonym Author)]. The raw data are available from the corresponding author upon request.

The distribution of the marine algal flora was assessed by grouping the 28 coastal provinces into seven coastal regions based on their meteorological and environmental conditions. The adjacent provinces of Thai Binh, Nam Dinh and Ninh Binh are pooled as species records were too scarce within these provinces. No records were available for the following provinces: Tien Giang, Ben Tre, Tra Vinh, Soc Trang, Bac Lieu and Ca Mau.

Vietnamese seaweed flora were compared with those of neighbouring countries using Sørensen’s similarity index (Magurran 1988). The floristic data of the neighbouring countries were derived from Algaebase and, for Taiwan, complemented by species records from Orchid Island (Lin 2012).

Notes

Sargassum nigrifolium Yendo, S. nipponicum Yendo, S. patens var. vietnamese nom. nud., S. tortile C. Agardh, S. tosaense Yendo were removed from the Vietnamese flora on the authority of Yoshida (2002a). Sargassum polycystum var. longicaule was removed on the authority of Nguyen H. Dai (1997, 2007).

The following species are not included in the checklist because they have not been formally described: Ceramium phuquocense nom. nud. [59], Gigartina vietnamensis nom. nud. [50], Solieria fastigiata nom. nud. [45, 69], Caulerpa minuta nom. nud. [21] and Chaetomorpha patentiramea nom. nud. [9].

Diversity of marine macroalgae in Vietnam

The present checklist contains a total of 827 species (180 Chlorophyta, 147 Phaeophyceae, 412 Rhodophyta and 88 Cyanobacteria) compiled from all earlier species records in both international and Vietnamese publications. This work represents the most inclusive list of Vietnamese flora to date, including 623 species more than in Dawson’s first list (Dawson 1954), and 157 species more than reported on Algaebase (Guiry and Guiry 2012). This checklist offers an up-to-date overview of Vietnamese algal flora and considerably improves its accessibility to the international community. Importantly, the checklist provides currently accepted species names for Vietnamese seaweeds. Continuous taxonomic refinement means that a considerable proportion (<one third) of taxon names listed in earlier publications, such as Dawson (1954), Pham H.H. (1969) and Nguyen H. Dinh et al. (1993), are no longer considered currently accepted.

The bulk of new records of seaweeds from Vietnam were published in a few publications only (e.g., Dawson 1954, Pham H.H. 1969 and Nguyen H. Dinh et al. 1993). Despite an increase in the number of algal publications from the 1990s onward, the discovery rate of new records seems to diminish (Figures 1 and 2). From this, the question arises whether we are getting close to documenting most of the Vietnamese seaweed diversity. Previous diversity estimates resulted in a figure of nearly 1000 seaweed species for the Vietnamese coast (Huynh and Nguyen H. Dinh 1998, Dang et al. 2007). In contrast, Algaebase reports only 670 taxa (Guiry and Guiry 2012), but this figure is only indicative as a number of publications were not included yet (e.g., Pham H.H. 1985, Nguyen H. Dinh et al. 1993, Nguyen H. Dai 1997, Nguyen H. Dai et al. 2000, Nguyen H. Dai and Pham H.T. 2003, Le N.H. 2000, 2001, 2004, Dam 2003, Le N.H. and Nguyen H. Dai 2006, Nguyen V. Tien 2007).

Distribution of seaweeds along the Vietnamese coast

Locality data have been included in the database of Vietnamese seaweeds, enabling us, to some extent, to analyse biogeographic and richness patterns (Figure 3). Of the 20 studied provinces, 12 have over 100 species, of which two are northern provinces (Quang Ninh, Hai Phong), seven are central provinces (Thanh Hoa, Quang Tri, Da Nang, Quang Ngai, Khanh Hoa, Ninh Thuan, Binh Thuan) and two are southern provinces (Ba Ria - Vung Tau, Kien Giang). Totals of 60 and 197 species are reported from the offshore Paracel and Spratly islands, respectively. The greatest species number (418) has been reported for the Khanh Hoa province, where half of the total number of species in Vietnam have been found. In general, the highest marine macroalgal diversity has been recorded for the South Central Coast region. The differences in species diversity among the provinces and regions are most likely influenced by differences in research efforts. The South Central region has traditionally been the most extensively investigated region. At least one-third of the publications on Vietnam’s seaweed flora focus on the Khanh Hoa province or its vicinity. This region was popular with visiting international phycologists (e.g., Dawson 1954, Abbott et al. 2002, Tsutsui et al. 2005). However, the high diversity might be sustained by the habitat heterogeneity of this region, or by increased primary productivity caused by local upwelling.

Diversity of marine macroalgae in Vietnam compared to neighbouring countries

The diversity of the Vietnamese seaweeds was compared with those of a number of neighbouring countries (Malaysia, Philippines, Taiwan and Thailand). The Philippines appear to be the most diverse country with a staggering total of 1011 species, whereas Vietnam harbours a comparable 827 species (Figure 4). Sørensen similarity indexes are low (Cs<0.5; Table 1). These low values are counterintuitive. Within similar climatic zones and in the absence of major dispersal barriers, marine biodiversity is expected to be much more homogenous (see Spalding et al. 2007). Even though we cannot rule out the existence of a biogeographical pattern making the Vietnamese seaweed flora highly distinct, 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, listing the Vietnamese seaweed diversity and stimulating intraregional comparative research. It may then become clear that many local endemics have a much wider distribution.
