Ecological insights into the coexistence of dormancy and desiccation-sensitivity in Arecaceae species

Mechanisms controlling germination of > 2600 Arecaceae species adapted to the tropical forests are not clearly understood. This contribution underpins notion that coexistence dormancy and desiccation sensitivity in some could significantly affect ecology. Although evolutionary ecological significance behind this occurrence is unknown, these traits together limit from inappropriate depths allow dispersal. Dormancy sensitivity, i.e., recalcitrance, considered as mutually exclusive evolved maximize seed survival after dispersal; former by allowing seeds spread risk temporally then synchronize with a favorable growing season, latter immediately. However, few temperate ecosystems have been known produce both dormant desiccation-sensitive, but little about such relationship forests. To understand if can coexist species, distributed predominantly forests, compare found other desiccation-sensitive species. Information published international peer-reviewed journals was reviewed database records on created discussed. literature survey has identified diaspores 34 desiccation-sensitivity an underdeveloped, small embryo, morphophysiological or morphological dormancy. In neither confined large-sized diaspores, nor all dry disperse diaspore during wet-season; features reported be prevalent families. Endocarp proposed act mechanical barrier preventing water loss also offer protection against physical damage; however, extent internal structures contentious. The possible unique noted currently review puts forward “testable” hypotheses call for more studies ecology focusing dispersal burial.
