Marine macrophyte strandings in the Yucatan peninsula: Citizen science as a potential tool for long-term monitoring
Aquatic Botany(2024)
摘要
Massive strandings of seaweeds on the eastern coasts of the Yucat ' an peninsula, Mexico have become a major socioecological problem, creating the need for establishing a baseline monitoring program in the region. A citizen science initiative, Big Seaweed Search Mexico (BSS-Mx), was developed to monitor temporal changes in the biomass stranded (abundance and species composition) in the Yucat ' an peninsula. The initiative was tested in two regions; Puerto Morelos, Quintana Roo, where massive strandings of Sargassum have caused severe socioecological impacts, and Sisal, Yucat ' an, where there is scarce information about the species composition of the strandings and their seasonal dynamics. Even the different socioeconomic and ecological context of these regions, the public participation in close collaboration with research scientists allowed detection of the temporal changes in the abundance and species composition of the strandings in both locations over a period of ten months. A total of 45 taxa were identified in Puerto Morelos, from which pelagic Sargassum and a seagrass were dominant for most time of the year; whereas 58 taxa were identified in Sisal, observing a higher diversity dominated by red seaweeds, with dominant taxa changing seasonally. The results represent baseline information that should be considered to develop management strategies and marine conservation actions according to each region. The findings highlight the role of citizen science as a potential tool to conduct large-scale and long-term monitoring and stimulate public participation to address environmental issues.
