Data from: Source population characteristics affect heterosis following genetic rescue of fragmented plant populationsMelinda Pickup, David L. Field, David M. Rowell & Andrew G. Young
Understanding the relative importance of heterosis and outbreeding depression over multiple generations is a key question in evolutionary biology and is essential for identifying appropriate genetic sources for population and ecosystem restoration. Here we use 2455 experimental crosses between 12 population pairs of the rare perennial plant Rutidosis leptorrhynchoides (Asteraceae) to investigate the multi-generational (F1, F2, F3) fitness outcomes of inter-population hybridisation. We detected no evidence of outbreeding depression, with inter-population hybrids and backcrosses showing...
Data from: Predicting local adaptation in fragmented plant populations: implications for restoration geneticsMelinda Pickup, David L. Field, David M. Rowell & Andrew G. Young
Understanding patterns and correlates of local adaptation in heterogeneous landscapes can provide important information in the selection of appropriate seed sources for restoration. We assessed the extent of local adaptation of fitness components in 12 population pairs of the perennial herb Rutidosis leptorrhynchoides (Asteraceae) and examined if spatial scale (0.7 – 600km), environmental distance, quantitative Q_ST and neutral genetic differentiation F_ST, and size of the local and foreign populations could predict patterns of adaptive differentiation....
Data from: Understanding age-specific dispersal in fishes through hydrodynamic modelling, genetic simulations and microsatellite DNA analysisOliver Berry, Philip England, Ross J. Marriot, Stephen J. Newman & Christopher P. Burridge
Many marine species have vastly different capacities for dispersal during larval, juvenile and adult life stages, and this has the potential to complicate the identification of population boundaries and the implementation of effective management strategies such as marine protected areas. Genetic studies of population structure and dispersal rarely disentangle these differences and usually provide only lifetime-averaged information that can be considered by managers. We address this limitation by combining age-specific autocorrelation analysis of microsatellite genotypes,...
Data from: Transcriptome analysis reveals novel patterning and pigmentation genes underlying Heliconius butterfly wing pattern variationHeather M. Hines, Riccardo Papa, Mayte Ruiz, Alexie Papanicolaou, Charles Wang, H. Frederik Nijhout, W. Owen McMillan & Robert D. Reed
BACKGROUND: Heliconius butterfly wing pattern diversity offers a unique opportunity to investigate how natural genetic variation can drive the evolution of complex adaptive phenotypes. Positional cloning and candidate gene studies have identified a handful of regulatory and pigmentation genes implicated in Heliconius wing pattern variation, but little is known about the greater developmental networks within which these genes interact to pattern a wing. Here we took a large-scale transcriptomic approach to identify the network of...
