Data from: Resistance to a bacterial parasite in the Crustacean Daphnia magna shows Mendelian segregation with dominance

Pepijn Luijckx, Harris Fienberg, David Duneau & Dieter Ebert
The influence of host and parasite genetic background on infection outcome is a topic of great interest because of its pertinence to theoretical issues in evolutionary biology. In the present study we use a classical genetics approach to examine the mode of inheritance of infection outcome in the crustacean Daphnia magna when exposed to the bacterial parasite Pasteuria ramosa. In contrast to previous studies in this system we use a clone of P. ramosa, not...

Data from: Multiple quantitative trait loci influence intra-specific variation in genital morphology between phylogenetically distinct lines of Drosophila montana

Martin A Schäfer, Jarkko Routtu, Jorge Vieira, Anneli Hoikkala, Mike G Ritchie & Christian Schlötterer
The evolution of animal genitalia has gained renewed interest, because of their potential roles during sexual selection and early stages of species formation. Although central to understanding the evolutionary process, knowledge of the genetic basis of natural variation in genital morphology is limited to a very few species. Using an out-bred cross between phylogenetically distinct lines of Drosophila montana, we characterized quantitative trait loci (QTLs) affecting the size and shape of the distiphallus, a prominent...

Data from: AFLP markers reveal high clonal diversity and extreme longevity in four arctic-alpine key species

Lucienne C. De Witte, Georg F.J. Armbruster, Ludovic Gielly, Pierre Taberlet & Jürg Stöcklin
We investigated the clonal diversity, genet size structure and genet longevity in populations of four arctic-alpine plants (Carex curvula, Dryas octopetala, Salix herbacea and Vaccinium uliginosum) in order to evaluate their persistence under past climatic oscillations and their potential resistance to future climate change. The size and number of genets was determined with molecular markers (AFLP) using a standardized sampling design in several homogenous climax populations across arctic-alpine regions in Europe. Genet age was estimated...

Data from: Quantitative genetic inheritance of morphological divergence in a lake-stream stickleback ecotype pair: implications for reproductive isolation

Daniel Berner, Renaud Kaeuffer, Anne-Catherine Grandchamp, Joost A. M. Raeymaekers, Katja Räsänen & Andrew P. Hendry
Ecological selection against hybrids between populations occupying different habitats might be an important component of reproductive isolation during the initial stages of speciation. The strength and directionality of this barrier to gene flow depends on the genetic architecture underlying divergence in ecologically relevant phenotypes. We here present line cross analyses of inheritance for two key foraging-related morphological traits involved in adaptive divergence between stickleback ecotypes residing parapatrically in lake and stream habitats within the Misty...

Data from: Citizen science reveals unexpected continental-scale evolutionary change in a model organism

Jonathan Silvertown, Laurence Cook, Robert Cameron, Mike Dodd, Kevin McConway, Jenny Worthington, Peter Skelton, Christian Anton, Oliver Bossdorf, Bruno Baur, Menno Schilthuizen, Benoît Fontaine, Helmut Sattmann, Giorgio Bertorelle, Maria Correia, Cristina Oliveira, Beata Pokryszko, Małgorzata Ożgo, Arturs Stalažs, Eoin Gill, Üllar Rammul, Péter Sólymos, Zoltan Féher & Xavier Juan
Organisms provide some of the most sensitive indicators of climate change and evolutionary responses are becoming apparent in species with short generation times. Large datasets on genetic polymorphism that can provide an historical benchmark against which to test for recent evolutionary responses are very rare, but an exception is found in the brown-lipped banded snail (Cepaea nemoralis). This species is sensitive to its thermal environment and exhibits several polymorphisms of shell colour and banding pattern...

Data from: Plasticity of animal genome architecture unmasked by rapid evolution of a pelagic tunicate

Olsen, Claire Jubin, Cristian Cañestro, Jean-Marie Bouquet, Gemma Danks, Julie Poulain, Coen Campsteijn, Marcin Adamski, Ismael Cross, Fekadu Yadetie, Matthieu Muffato, Alexandra Louis, Stephen Butcher, Georgia Tsagkogeorga, Anke Konrad, Sarabdeep Singh, Marit F. Jensen, Evelyne Huynh Cong … & Daniel Chourrout
Genomes of animals as different as sponges and humans show conservation of global architecture. Here we show that multiple genomic features including transposon diversity, developmental gene repertoire, physical gene order, and intron-exon organization are shattered in the tunicate Oikopleura, belonging to the sister group of vertebrates and retaining chordate morphology. Ancestral architecture of animal genomes can be deeply modified and may therefore be largely nonadaptive. This rapidly evolving animal lineage thus offers unique perspectives on...

Data from: Separated by sand, fused by dropping water: habitat barriers and fluctuating water levels steer the evolution of rock-dwelling cichlid populations in Lake Tanganyika

Stephan Koblmüller, Walter Salzburger, Beate Obermüller, Eva Eigner, Christian Sturmbauer & Kristina M Sefc
The conditions of phenotypic and genetic population differentiation allow inferences about the evolution, preservation and loss of biological diversity. In Lake Tanganyika, water level fluctuations are assumed to have had a major impact on the evolution of stenotopic littoral species, though this hypothesis has not been specifically examined so far. The present study investigates whether subtly differentiated color patterns of adjacent Tropheus moorii populations are maintained in isolation or in the face of continuous gene...
