Global map showing the change in (a) sea surface temperature (SST), (b) salinity (SSS), and (c) density (SSD) across mangrove bioregions under RCP 8.5. Changes in SST and SSS are based on present-day (2000-2014) and future (2090-2100) marine fields from the Bio-ORACLE database, from which SSD data were derived. The vertical line (19° E) separates the two major mangrove bioregions: the Atlantic-East Pacific (AEP) and the Indo-West Pacific (IWP).

An international research led the VUB Biology Department examined 21 st century changes in ocean-surface temperature, salinity, and density, across mangrove forests worldwide. The study suggests that changes in surface-ocean density may impact the dispersal patterns of widely distributed mangroves species, and more likely so in the Indo-West Pacific region, the primary hotspot of mangrove diversity. The study is published in the renowned Nature Climate Change.

"Climate change affects sea-surface density via changes in temperature and salinity. Since propagules of widely distributed mangroves species have densities near that of seawater, changes in ocean density hold implications for oceanic dispersal of mangroves. ...
