“…Changes in marine flora from the 1990s to 2008¡2012 showed the same tendency (Titlyanov et al, 2014b). However, two studies in other regions did not detect decrease of macroalgal species richness from Yonaguni Island (Ryukyu Archipelago, Japan) between spring 1935 and spring 2013 and from Nha Trang Bay (southern Vietnam) among 1953-1969, 1982-1986and 2002-2010(Titlyanov et al, 2014c. The differences between them were mostly likely because of differences in nutrient pollution and decrease of habitats due to anthropogenic disturbances.…”

“…In our previous studies (Titlyanov et al, 2014c), the algal collections decreased from 392 species in the 1930-1970's to 207 species in the 1990/1992. During the period (50 years) between these samplings, 217 species were not found again and 104 newly recorded species were documented.…”

“…During previous several decades, three extensive samplings of macroalgae on coral reefs were performed at Hainan Island (as reviewed in Titlyanov et al, 2014c). Significant differences in species richness and composition of marine macrophytes were found in the algal collections from the 1930-1970's and 1990/1992 and then 2008-2010, probably as a consequence of coral reef degradation and pollution of the sea by mariculture waste (Zhang et al, 2006;Huang et al, 2013;Hughes et al, 2013;Li et al, 2015).…”

Degradation processes on coral reefs are associated with changes in macroalgal assemblages. In this study, a floristic study of the macrophyte species on coral reefs along a pollution gradient at 3 transects in southern Hainan Island, China, was conducted in April 2014. A total of 73 benthic macroalgal taxa were collected, of which 58% were reds, 23% browns and 19% greens. Along with the distance away from the outlet of fish farms, macroalgal species richness increased significantly from 40 species to 71 species. However, macroalgal biomass decreased from 1.58 kg m ¡2 to 1.1 kg m ¡2 . Brown blooms of Chnoospora implexa, Padina australis, Sargassum polycystum and S. sanyaense changed to green blooms of Ulva lactuca and Caulerpa racemosa from moderately polluted sites to severely polluted sites close to the outlet. This study supports the results that severe pollution can lead not only to a significant decline of macroalgal species richness and changes in macroalgal assemblages, but also to the occurrence of green blooms. This study will hopefully provide more accurate cases to link nutrient pollution to changes in benthic organisms on coral reefs.

“…The records of algal species contained in our previous studies [13][14][15][16][17][18][19][20] suggest that conspicuous changes in the composition and diversity of red algae have occurred between the 1930s and 2012. Counter-intuitively, there has been a decline in total species richness despite the appearance of many newly reported species.…”

“…A third sampling was performed during 2008-2016 (LC) (Figure 1). Some of the results of this algal inventory have also been published [13][14][15]17,19,20], with 301 species being recorded including 163 (54%) Rhodophyta, 50 (17%) Phaeophyceae, and 88 (29%) Chlorophyta. This further paper presents an annotated list of new findings of red algae for Hainan Island made during the course of this study.…”

Abstract:We present an annotated list of new finds of red algae from Hainan Island, Southern China, including those found in 1990 and 1992 during the German-Chinese expeditions to Hainan Island and in 2008-2016 by Titlyanova, Titlyanov, and Li. Between 1990 and 1992, a total of 64 taxa of red algae were newly recorded for Hainan Island. Of these 15 species were new records for China. During the period 2008-2016, a further 54 taxa were newly recorded for Hainan Island, of which 20 were new records for China. The full list of new taxa includes taxonomic forms, dates, and locales, together with known biogeographical distributions. During both periods, the apparent enrichment of red algal marine flora has occurred in a similar way-mainly at the expense of epiphytes with filamentous, thin-filamentous, and finely branched forms. We believe that the changes in the flora of Hainan Island have been influenced by both anthropogenic and natural factors including in particular exploitation of herbivores, nutrient pollution, and coral bleaching.
