中国科学院武汉植物园王青锋等研究人员合作揭示马达加斯加猴面包树的崛起。相关论文于2024年5月15日在线发表于国际学术期刊《自然》。
研究人员对所有八个现存猴面包树种的基因组进行了测序，并认为马达加斯加应被视为现存树系的起源中心，这是猴面包树演化史上的一个关键问题。综合基因组学和生态学分析揭示了猴面包树的网状沿海过程，最终形成了今天的物种多样性。马达加斯加猴面包树过去的种群动态可能受到了种间竞争和岛屿地质历史的影响，尤其是当地海平面的变化。
研究人员建议，应进一步关注马达加斯加猴面包树的保护状况，尤其是adansonia suarezensis和adansonia grandidieri，而且鉴于adansonia za会对极度濒危的adansonia perrieri造成负面影响，因此需要对其种群进行密集监测。
研究人员表示，猴面包树（猴面包树属）因其引人注目的外形和与动物的独特关系而备受关注。这些壮观的树木还影响了人类文化，激发了无数艺术、民间传说和传统。

abstract: the baobab trees (genus adansonia) have attracted tremendous attention because of their striking shape and distinctive relationships with fauna1. these spectacular trees have also influenced human culture, inspiring innumerable arts, folklore and traditions. here we sequenced genomes of all eight extant baobab species and argue that madagascar should be considered the centre of origin for the extant lineages, a key issue in their evolutionary history2,3. integrated genomic and ecological analyses revealed the reticulate evolution of baobabs, which eventually led to the species diversity seen today. past population dynamics of malagasy baobabs may have been influenced by both interspecific competition and the geological history of the island, especially changes in local sea levels. we propose that further attention should be paid to the conservation status of malagasy baobabs, especially of adansonia suarezensis and adansonia grandidieri, and that intensive monitoring of populations of adansonia za is required, given its propensity for negatively impacting the critically endangered adansonia perrieri.
