Supplementary material for: Phylogenomics and historical biogeography of seahorses, dragonets, goatfishes, and allies (Teleostei: Syngnatharia): Assessing factors driving uncertainty in biogeographic inferences

The charismatic trumpetfishes, goatfishes, dragonets, flying gurnards, seahorses, and pipefishes encompass a recently defined yet extraordinarily diverse clade of percomorph fishes—the series Syngnatharia. This group is widely distributed in tropical and warm-temperate regions, with a great proportion of its extant diversity occurring in the Indo-Pacific. Because most syngnatharians feature long-range dispersal capabilities, tracing their biogeographic origins is challenging. Here, we applied an integrative phylogenomic approach to elucidate the evolutionary biogeography of syngnatharians. We built upon a recently published phylogenomic study that examined ultraconserved elements by adding 62 species (total 169 species) and one family (Draconettidae), to cover ca. 25% of the species diversity and all 10 families in the group. We inferred a set of time-calibrated trees and conducted ancestral range estimations. We also examined the sensitivity of these analyses to phylogenetic uncertaint...颇具特色的管口鱼（trumpetfishes）、羊鱼（goatfishes）、䲗类（dragonets）、飞角鱼（flying gurnards）、海马（seahorses）以及海龙（pipefishes），隶属于新近界定却物种多样性极高的真鲈形类鱼类（percomorph fishes）支系——海龙形类群（Syngnatharia）。该类群广泛分布于热带及暖温带海域，其现存物种的绝大多数多样性集中于印度-太平洋海域。由于多数海龙形类群具备长距离扩散能力，解析其生物地理起源颇具挑战。本研究采用整合系统发育组学方法，阐明了海龙形类群的演化生物地理学格局。我们基于一项新近发表的针对超保守元件（ultraconserved elements）的系统发育组学研究，新增62个物种（总物种数达169种）及1个科（䲗科Draconettidae），覆盖该类群约25%的物种多样性，并纳入了该类群全部10个科。我们构建了一系列时间校准树，并开展了祖先分布区重建分析。此外，我们还检验了这些分析结果对系统发育不确定性的敏感性……
