Data from: Evolution of woody life form on tropical mountains in the tribe Spermacoceae (Rubiaceae)

Suman Neupane, Paul O. Lewis, Steven Dessein, Hunter Lee Shanks, Sushil Paudyal, Frederic Lens & Hunter Shanks
Spermacoceae are mainly an herbaceous group in the Rubiaceae. However, a few lineages are woody, and are found in a diverse range of habitat types. Three of the largest woody lineages (Arcytophyllum, Hedyotis, and Kadua) are characterized by their distribution in the moist tropical mountains, and have disjunct distribution patterns with respect to their closest relatives. In this study, we explore the cases of derived woodiness in these three lineages and their diversification dynamics in...

Data from: Lineages of Silene nutans developed rapid, strong, asymmetric postzygotic reproductive isolation in allopatry

Helene Martin, Pascal Touzet, Mathilde Dufay, Cécile Godé, Eric Schmitt, Emna Lahiani, Lynda F. Delph & Fabienne Van Rossum
Reproductive isolation can rise either as a consequence of genomic divergence in allopatry or as a byproduct of divergent selection in parapatry. To determine whether reproductive isolation in gynodioecious Silene nutans results from allopatric divergence or from ecological adaptation following secondary contact, we investigated the pattern of postzygotic reproductive isolation and hybridization in natural populations using two phylogeographic lineages, western (W1) and eastern (E1). Experimental crosses between the lineages identified strong, asymmetric postzygotic isolation between...

Data from: Ex situ cultivation entails high risk of seed dormancy loss on short-lived wild plant species

Andreas Ensslin, Ann Van De Vyver, Thierry Vanderborght & Sandrine Godefroid
1. Changes in life-history traits such as seed dormancy during cultivation of wild plant species in ex situ facilities could jeopardise conservation actions such as revegetation and plant reintroductions, but the magnitude of these risks and their spread across different plant taxa is unknown. 2. In this study, we explored whether plants cultivated in the Botanic Garden Meise differ in seed germination characteristics from plants from natural populations. Using a Bayesian approach of a phylogenetically...
