Mangroves and their reproductive strategies. Three kinds of reproductive strategies in mangrove plants were shown: true-vivipary, crypto-vivipary and non-vivipary with their representative species (Photographed by Wang Wen-Qing). The left picture illustrates the hypocotyls of true-vivipary species Kandelia obovata. The middle picture shows the fruits of crypto-vivipary species Avicennia marina. The right picture presents the fruits of non-vivipary species Sonneratia alba. The background picture displays the population of Aegiceras corniculatum in Zhangjiangkou Mangrove National Reserve, Yunxiao, Fujian. Zhou et al. reported the progress on the studies of viviparity on mangrove plants from four aspects: anatomy, physiology and biochemistry, molecular biology and ecological adaptations (Pages 1328–1343 of this issue).
