Data from: Does divergent selection predict the evolution of mate preference and reproductive isolation in the tropical butterfly genus Melinaea (Nymphalidae: Ithomiini)?Melanie McClure, Louiza Mahrouche, Céline Houssin, Monica Monllor, Yann Le Poul, Brigitte Frérot, Alexandra Furtos & Marianne Elias
Many studies have shown that speciation can be facilitated when a trait under divergent selection also causes assortative mating. In Müllerian mimetic butterflies, a change in wing colour pattern can cause reproductive isolation. However, colour pattern divergence does not always lead to reproductive isolation. Understanding how divergent selection affects speciation requires identifying the mechanisms that promote mate preference and/or choosiness. This study addresses whether shifts in wing colour pattern drives mate preference and reproductive isolation...
Data from: Why has transparency evolved in aposematic butterflies? insights from the largest radiation of aposematic butterflies, the IthomiiniMelanie McClure, Corentin Clerc, Charlotte Desbois, Aimilia Meichanetzoglou, Marion Cau, Lucie Bastin-Héline, Javier Bacigalupo, Céline Houssin, Charline Pinna, Bastien Nay, Violaine Llaurens, Serge Berthier, Christine Andraud, Doris Gomez & Marianne Elias
Defended species are often conspicuous and this is thought to be an honest signal of defences, i.e. more toxic prey are more conspicuous. Neotropical butterflies of the large Ithomiini tribe numerically dominate communities of chemically-defended butterflies and may thus drive the evolution of mimetic warning patterns. Although many species are brightly coloured, most are transparent to some degree. The evolution of transparency from a warningly coloured ancestor is puzzling as it is generally assumed to...
Data from: Macroevolutionary analyses suggest that environmental factors, not venom apparatus, play key role in Terebridae marine snail diversificationMaria Vittoria Modica, Juliette Gorson, Alexander E. Fedosov, Gavin Malcolm, Yyves Terryn, Nicolas Puillandre & Mandë Holford
How species diversification occurs remains an unanswered question in predatory marine invertebrates, such as sea snails of the family Terebridae. However, the anatomical disparity found throughput the Terebridae provides a unique perspective for investigating diversification patterns in venomous predators. In this study, a new dated molecular phylogeny of the Terebridae is used as a framework for investigating diversification of the family through time, and for testing the putative role of intrinsic and extrinsic traits, such...
Data from: Habitat diversity associated with island size and environmental filtering control the species richness of rock-savanna plants in neotropical inselbergsLudovic Henneron, Corinne Sarthou, Jean-Christophe De Massary & Jean-François Ponge
Disentangling the multiple factors controlling species diversity is a major challenge in ecology. Island biogeography and environmental filtering are two influential theories emphasizing respectively island size and isolation, and the abiotic environment, as key drivers of species richness. However, few attempts have been made to quantify their relative importance and investigate their mechanistic basis. Here, we applied structural equation modelling, a powerful method allowing test of complex hypotheses involving multiple and indirect effects, on an...
