      abstract     = {Some of the most striking features of Rhizophoraceae
                      mangrove saplings are their voluminous cylinder-shaped
                      hypocotyls and thickened leaves. The hypocotyls are known to
                      serve as floats during seed dispersal (hydrochory) and store
                      nutrients that allow the seedling to root and settle. In
                      this study we investigate to what degree the hypocotyls and
                      leaves can serve as water reservoirs once seedlings have
                      settled, helping the plant to buffer the rapid water
                      potential changes that are typical for the mangrove
                      environment. We exposed saplings of two Rhizophoraceae
                      species to three levels of salinity (15, 30, and 0–5‰,
                      in that sequence) while non-invasively monitoring changes in
                      hypocotyl and leaf water content by means of mobile NMR
                      sensors. As a proxy for water content, changes in hypocotyl
                      diameter and leaf thickness were monitored by means of
                      dendrometers. Hypocotyl diameter variations were also
                      monitored in the field on a Rhizophora species. The saplings
                      were able to buffer rapid rhizosphere salinity changes using
                      water stored in hypocotyls and leaves, but the largest water
                      storage capacity was found in the leaves. We conclude that
                      in Rhizophora and Bruguiera the hypocotyl offers the bulk of
                      water buffering capacity during the dispersal phase and
                      directly after settlement when only few leaves are present.
                      As saplings develop more leaves, the significance of the
                      leaves as a water storage organ becomes larger than that of
                      the hypocotyl.},
