Data from: Altered gene expression and ecological divergence in sibling allopolyploids of Dactylorhiza (Orchidaceae)

Ovidiu Paun, Richard M. Bateman, Michael F. Fay, Javier A. Luna, Justin Moat, Mikael Hedrén & Mark W Chase
Background: Hybridization and polyploidy are potent forces that have regularly stimulated plant evolution and adaptation. Dactylorhiza majalis s.s., D. traunsteineri s.l. and D. ebudensis are three allopolyploid species of a polyploid complex formed through unidirectional (and, in the first two cases, recurrent) hybridization between the widespread diploids D. fuchsii and D. incarnata. Differing considerably in geographical extent and ecological tolerance, the three allopolyploids together provide a useful system to explore genomic responses to allopolyploidization and...

Data from: Strong male/male competition allows for nonchoosy females: high levels of polygynandry in a territorial frog with paternal care

Eva Ursprung, Max Ringler, Robert Jehle & Walter Hödl
Our knowledge about genetic mating systems and the underlying causes for and consequences of variation in reproductive success has substantially improved in recent years. When linked to longitudinal population studies, cross-generational pedigrees across wild populations can help answer a wide suite of questions in ecology and evolutionary biology. We used microsatellite markers and exhaustive sampling of two successive adult generations to obtain population-wide estimates of individual reproductive output of males and females in a natural...

Data from: Extensive range persistence in peripheral and interior refugia characterizes Pleistocene range dynamics in a widespread Alpine plant species (Senecio carniolicus, Asteraceae)

Pedro Escobar García, Manuela Winkler, Ruth Flatscher, Michaela Sonnleitner, Jana Krejčíková, Jan Suda, Karl Hülber, Gerald M. Schneeweiss & Peter Schönswetter
Recent evidence suggests that survival of arctic-alpine organisms in peripheral or interior glacial refugia are not mutually exclusive and may both be involved in shaping an organisms’ Pleistocene history, yet potentially at different time levels. Here, we test this hypothesis in a high-mountain plant (diploid lineage of Senecio carniolicus, Asteraceae) from the Eastern European Alps, in which patterns of morphological variation and current habitat requirements suggest survival in both types of refugia. To this end,...

Data from: Interploidal hybridization and mating patterns in the Sphagnum subsecundum complex

Mariana Ricca, P. Szövényi, Matthew G Johnson, A Jonathan Shaw & Eva M. Temsch
Polyploidization is thought to result in instant sympatric speciation, but several cases of hybrid zones between one of the parental species and its polyploid derivative have been documented. Previous work showed that diploid Sphagnum lescurii is an allopolyploid derived from the haploids S. lescurii (maternal progenitor) and S. subsecundum (paternal progenitor). Here we report the results from analyses of a population where allodiploid and haploid S. lescurii co-occur and produce sporophytes. We tested (1) whether...

Data from: The promiscuous and the chaste: frequent allopolyploid speciation and its genomic consequences in American daisies (Melampodium sect. Melampodium; Asteraceae)

Hanna Weiss-Schneeweiss, Cordula Blöch, Barbara Turner, José L. Villaseñor, Tod F. Stuessy & Gerald M. Schneeweiss
Polyploidy, an important factor in eukaryotic evolution, is especially abundant in angiosperms, where it often acts in concert with hybridization to produce allopolyploids. The application of molecular phylogenetic techniques has identified the origins of numerous allopolyploids, but little is known on genomic and chromosomal consequences of allopolyploidization, despite their important role in conferring divergence of allopolyploids from their parental species. Here, using several plastid and nuclear sequence markers, we clarify the origin of tetra- and...
