Guanabara Bay, the second largest bay on the Brazilian coast, has tropical to subtropical, hypereutrophic water conditions. A survey of the macroalgae flora conducted over the past 200 years (1800-2013) yielded a list of 245 species, which represents 15.7% of the total macroalgae recorded in the Tropical Western Atlantic, while comprehends 29.9% and 50.2% of the marine flora in Brazil and Rio de Janeiro, respectively. When evaluating the macroalgal list throughout different periods, it is noticeable the gradual loss of biodiversity as anthropization increased over the last two centuries. The use of phytogeographic indexes and beta diversity confirmed the negative changes in macroalgae assemblages as a response to increasing environmental degradation. The use of floristic surveys to establish the reference conditions employing historical data and/or regionally referenced prove to be an efficient tool using macroalgae as an ecological indicator for water quality.
瓜纳巴拉湾是巴西海岸的第二大港湾，拥有热带到亚热带、富营养化的水域条件。过去 200 年（1800-2013 年）对大型藻类植物区系进行的调查得出了 245 种物种的清单，占热带西大西洋记录的大型藻类总数的 15.7%，分别占巴西和里约热内卢海洋植物区系的 29.9%和 50.2%。当评估不同时期的大型藻类清单时，可以注意到随着过去两个世纪人类活动的增加，生物多样性逐渐丧失。植物地理指数和β多样性的使用证实了大型藻类组合的负面变化，这是对环境恶化的响应。使用植物区系调查来建立参考条件，利用历史数据和/或区域参考，使用大型藻类作为水质生态指标，是一种有效的工具。
