Data from: Demographic modelling with whole-genome data reveals parallel origin of similar Pundamilia cichlid species after hybridization

Joana I. Meier, Vitor C. Sousa, David Alexander Marques, Oliver M. Selz, Catherine E. Wagner, Laurent Excoffier & Ole Seehausen
Modes and mechanisms of speciation are best studied in young species pairs. In older taxa, it is increasingly difficult to distinguish what happened during speciation from what happened after speciation. Lake Victoria cichlids in the genus Pundamilia encompass a complex of young species and polymorphic populations. One Pundamilia species pair, P. pundamilia and P. nyererei, is particularly well suited to study speciation because sympatric population pairs occur with different levels of phenotypic differentiation and reproductive...

Data from: Genomic landscape of early ecological speciation initiated by selection on nuptial colour

David Alexander Marques, Kay Lucek, Marcel Philipp Haesler, Anna Fiona Feller, Joana Isabel Meier, Catherine Wagner, Laurent Excoffier, Ole Seehausen & Catherine E. Wagner
Ecological speciation is the evolution of reproductive isolation as a consequence of direct divergent natural selection or ecologically mediated divergent sexual selection. While the genomic signature of the former has been extensively studied in recent years, only few examples exist for genomic differentiation where environment-dependent sexual selection has played an important role. Here, we describe a very young (~90 years old) population of threespine sticklebacks exhibiting phenotypic and genomic differentiation between two habitats within the...

Data from: Manipulating virulence factor availability can have complex consequences for infections

Michael Weigert, Adin Ross-Gillespie, Anne Leinweber, Gabriella Pessi, Sam P. Brown & Rolf Kuemmerli
Given the rise of bacterial resistance against antibiotics, we urgently need alternative strategies to fight infections. Some propose we should disarm rather than kill bacteria, through targeted disruption of their virulence factors. It is assumed that this approach (i) induces weak selection for resistance because it should only minimally impact bacterial fitness, and (ii) is specific, only interfering with the virulence factor in question. Given that pathogenicity emerges from complex interactions between pathogens, hosts, and...

Data from: Niche width impacts vertebrate diversification

Jonathan Rolland & Nicolas Salamin
Aim: The size of the climatic niche of a species is a major factor determining its distribution and evolution. In particular, it has been proposed that niche width should be associated with the rate of species diversification. Here, we test whether species niche width affects the speciation and extinction rates of three main clades of vertebrates: amphibians, mammals and birds. Location: Global. Methods: We obtained the time-calibrated phylogenies, IUCN conservation status, species distribution maps and...

Data from: Phylogeographic past and invasive presence of Arion pest slugs in Europe

Miriam A. Zemanova, Eva Knop & Gerald Heckel
Arion vulgaris (syn. A. lusitanicus) is the most destructive pest slug in Europe. The species has been regarded a classic case of an ongoing biological invasion with negative economic and ecological impact in many European countries, but this status has recently been contested. In this study, we assessed mitochondrial and autosomal genetic diversity in populations of A. vulgaris across the entire distribution range in order to characterize its evolutionary history. Mitochondrial diversity in A. vulgaris...
