项目标书摘要：The evolutionary success of a lineage may be measured by its species diversity or by its morphological disparity.Although diversity and disparity are not necessarily correlated,they are usually closely tied in adaptive radiations.Ecological opportunity commonly precedes adaptive radiations and can be triggered by events like mass extinctions,the origin of new resources(e.g.,landmasses and biomes),or the colonization of new areas.However,the relationship between niche shifts and adaptive radiations remains underexplored.Here we propose to use the genus Mimosa(Fabaceae)as a model to investigate how niche shifts are related to evolutionary radiations.Based on the idea that niche shifts can spark ecological opportunity,we hypothesize that radiation events in the genus were linked to niche shifts.To explore the evolutionary history of the genus and test our hypothesis,we will use phylogenetic,morphological,occurrence and environmental data to estimate their evolutionary rates(i.e.diversification,disparification and niche evolution).By answering our questions,we expect to develop a better view about the relationship between niche shifts and evolutionary radiations and about the contribution of such events to the diversity of species and forms in the mega-genus Mimosa.
