Abstract
Understanding the role of mangroves in microplastic (MPs) bioaccumulation is crucial to addressing the pollution in these ecosystems, particularly in restored areas. Here, we 1) evaluate the MPs plastic-biota-sediment accumulation factor (pBSAf) in the fiddler crab Minuca rapax and 2) describe MPs type, colour, and polymeric characteristics in areas with varying restoration and degradation levels in the Southern Gulf of Mexico. We used regression models to evaluate the role of mangrove tree height, basal area, and crab individuals' density in explaining pBSAf. The highest pBSAf values were observed in natural and restored mangrove areas, particularly those with higher crab densities and taller trees. MPs were more diverse in composition in both crabs and sediments from natural areas. Mangrove biota tissue's bioaccumulation may provide insights into ecosystem health and food web impacts and indicate restoration progress.
期刊介绍:
Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
