Abstract

Abstract Phylogenetic analyses can be used to resolve taxonomic uncertainties and reconstruct a species’ evolutionary history. This can be combined with ecological data to predict missing life history traits which are important for creation of conservation management strategies. We investigated the evolutionary and life history of the ‘Critically Endangered’ Grenada Dove Leptotila wellsi by estimating its phylogenetic placement and using this new phylogeny to test the accuracy of phylogenetic comparative methods for estimating both documented and unknown life history traits. We extracted DNA from two Grenada Dove samples and obtained sequences from three mitochondrial markers: Cytochrome oxidase I (COI), NADH dehydrogenase 2 (ND2) and Cytochrome b (Cyt b); and one nuclear marker: β-Fibrinogen intron 7 (β-FIB). We present the first genetic data obtained for the Grenada Dove. Our data identify the Grey-Chested Dove Leptotila cassinii as the species which shares both a most recent common ancestor, with an estimated divergence of approximately 2.53 million years ago, and the smallest genetic distance (P = 0.0303) with the Grenada Dove. Life history trait values for the Grenada Dove predicted from our analyses using phylogenetic imputation are: clutch size = 2 (± 0.09) eggs; clutches per year = 1.4 (± 0.81); incubation time = 14.2 (± 0.75) days; hatching weight = 3.8 g (± 1.05) and single imputation: fledging age (genus median) = 15.5 days, longevity (genus median) = 8.6 years. This study contributes novel information regarding evolutionary history and life history characteristics to inform long-term conservation actions for a ‘Critically Endangered’ species.

格林纳达小飞鸽的系统发育定位及生活史性状归因

系统发育分析可以用来解决分类上的不确定性和重建物种的进化史。这可以与生态数据相结合，预测缺失的生活史特征，这对制定保护管理策略很重要。我们研究了“极度濒危”格林纳达鸽子的进化和生活史，通过估计其系统发育位置，并使用这一新的系统发育来测试系统发育比较方法在估计已知和未知生活史特征方面的准确性。我们从两个格林纳达鸽子样本中提取DNA，获得了三个线粒体标记的序列:细胞色素氧化酶I (COI)、NADH脱氢酶2 (ND2)和细胞色素b (Cyt b);和一个核标记:β-纤维蛋白原内含子7 (β-FIB)。我们提出了第一个遗传数据获得格林纳达鸽子。我们的数据确定了灰胸鸽Leptotila cassinii是与格林尼达鸽子具有最近共同祖先的物种，估计分歧约为253万年前，并且与格林尼达鸽子具有最小的遗传距离(P = 0.0303)。我们利用系统发育归算分析预测的格林纳达鸽子的生活史性状值为:窝数= 2(±0.09)个蛋;每年离合器= 1.4(±0.81);培养时间= 14.2(±0.75)天;孵化重量= 3.8 g(±1.05)，单次代入:雏龄(属中位数)= 15.5天，寿命(属中位数)= 8.6年。该研究提供了关于进化历史和生活史特征的新信息，为“极度濒危”物种的长期保护行动提供了信息。

期刊介绍： Bird Conservation International is a quarterly peer-reviewed journal that seeks to promote worldwide research and action for the conservation of birds and the habitats upon which they depend. The official journal of BirdLife International, it provides stimulating, international and up-to-date coverage of a broad range of conservation topics, using birds to illuminate wider issues of biodiversity, conservation and sustainable resource use. It publishes original papers and reviews, including targeted articles and recommendations by leading experts.
