Pett. ex Bramwell & Sunding and (A.Santos & M.Fernández) M.Will, N.Schmalz & Class.-Bockh. are two single-island endemic species from Fuerteventura (Canary Islands), inhabiting the same areas and similar habitats. They are under the "Critically Endangered" category due to historical herbivore pressure, mainly goats, leading to habitat fragmentation and poor population recruitment. The main aim of our study was to provide insights into the conservation genetics and habitat suitability of these two species. For this purpose, we sampled all known populations on the island and developed two new sets of microsatellite markers. Moreover, to assist restoration plans, we performed species distribution models to determine the most suitable areas for reintroduction. While is highly fragmented, with low genetic diversity indices in some populations, 's genetic structure is quite homogeneous, grouped in three main regions, with signs of inbreeding and an overall low genetic diversity. Both species could present moderate to high levels of autogamy. Our findings can provide guidance to local governments regarding conservation actions to be implemented in the field, like the identification of propagule sources and new suitable areas for restoration.
佩特（由布拉姆韦尔和桑丁命名）以及（A.桑托斯和M.费尔南德斯）M.威尔、N.施马尔茨和克拉斯-博克是来自富埃特文图拉岛（加那利群岛）的两种单岛特有物种，它们栖息在相同区域和相似栖息地。由于历史上食草动物的压力，主要是山羊，导致栖息地破碎化和种群补充不佳，它们被列为“极度濒危”物种。我们研究的主要目的是深入了解这两个物种的保护遗传学和栖息地适宜性。为此，我们对岛上所有已知种群进行了采样，并开发了两组新的微卫星标记。此外，为了协助恢复计划，我们进行了物种分布模型以确定最适合重新引入的区域。虽然佩特种群高度破碎，一些种群的遗传多样性指数较低，但[另一种物种名称未明确]的遗传结构相当均匀，分为三个主要区域，存在近亲繁殖迹象且总体遗传多样性较低。两种物种都可能呈现中度到高度的自花授粉。我们的研究结果可以为地方政府在实地实施保护行动提供指导，比如确定繁殖体来源和新的适宜恢复区域。
