In Brazil’s North region, members of the population of red mangrove trees (Rhizophora mangle) do not often meet relatives from the South and vice-versa. However, occasional migrations via ocean currents between the two regions involving propagules, seeds adapted to seawater, enable populations to exchange genetic material and remain connected during their evolution.
