Data from: the two faces of secondary contact on islands: introgressive hybridization between endemics and reproductive interference between endemics and introduced species

Aim: Hybridization is thought to have played an important role in shaping the evolutionary history of diverse island taxa. Here, we propose an ecological and evolutionary framework for understanding the causes and consequences of heterospecific mating on islands – with and without introgressive hybridization. We use this framework to support our main contention that cases of secondary contact among endemic species should commonly result in introgressive hybridization whereas cases of contact between endemic and introduced species should commonly result in reproductive interference – resulting in two qualitatively different faces of secondary contact on islands. Location: Canary Islands, Galapagos, New Zealand, Caribbean, and Hawaii. Taxa: 705 vertebrate, invertebrate, and plant species spanning 167 genera and 99 families. Methods: Using a quantitative analysis of empirical research on secondary contact on islands, we weigh evidence for the drivers of secondary contact and heterospecific mating on islands. In particular, we compare cases of secondary contact between endemic species versus secondary contact between endemic and introduced species. Results: We find that three main drivers of secondary contact and heterospecific mating on islands most frequently reported in the literature are disturbance, long-distance (e.g. inter-island) dispersal, and compromised assortative mating. We find support for the hypothesis that introgression is a more common outcome between endemic species while reproductive interference is a more common outcome between endemic and introduced species. Main conclusions: We conclude that there are biological reasons to predict secondary contact and heterospecific mating to be common on islands for all taxa, but that the consequence of secondary contact is categorically different for contact between endemic species and contact between endemic and introduced species. We conclude that the former likely explains the apparent frequency of hybridization on islands, while the latter presents a cryptic and underappreciated conservation threat.

Raveta in lateral view: K. luciae (two flowers on the left), K. thyrsiflora (two flowers to the right of those of K. luciae), K. crouchii (two flowers to the right of those of K. thyrsiflora), and K. deliae (two flowers on the right). Note that the flowers of K. deliae have the longest sepals by far, with the sepals in some cases being virtually as long as the corolla tube. Photograph: Gideon F. Smith.

FIGURE 1. Kalanchoe deliae from central-east Mpumalanga, South Africa. A. Lower, leafy section of a stem. The opposite-decussate, amplexicaul, erect to slightly erectly spreading leaves are infused with rusty brown along the leaf margins only. B. Leaves are light green, obovate to broadly elliptic, sometimes very slightly curved up along margins and have a ± cuneate base that is sometimes very slightly auriculate. C. Roots are fibrous to slightly thickened and the stems are a uniform light green colour. D. The erect to leaning, club-shaped inflorescences are apically dense- and many-flowered. E. The flowering portion of the inflorescences is 110–130(–150) mm long and the branches are borne oppositely, with the branches slanted away from the main flowering stem at an angle of 10–15°. The internodes are very short, so yielding dense-clustered inflorescences. F. All plant parts are densely white-wax-covered. The adaxial surface of the corolla lobes are light green and light rusty brownish-infused towards the tips, with the margins usually paler. All photographs: Gideon F. Smith.
