Data from: A field test of a model for the stability of androdioecy in the freshwater shrimp, Eulimnadia texanaStephen C. Weeks, Chiara Benvenuto, Sadie K. Reed, Robert J. Duff, Zhong-Hui Duan, Patrice David & Z.-H. Duan
The evolution of hermaphroditism from dioecy is a poorly studied transition. Androdioecy (the coexistence of males and hermaphrodites) has been suggested as an intermediate step in this evolutionary transition or could be a stable reproductive mode. Freshwater crustaceans in the genus Eulimnadia have reproduced via androdioecy for 24+ million years and thus are excellent organisms to test models of the stability of androdioecy. Two related models that allow for the stable maintenance of males and...
Data from: Phenotypic divergence of the common toad (Bufo bufo) along an altitudinal gradient: evidence for local adaptationEmilien Luquet, Jean-Paul Léna, Claude Miaud & Sandrine Plénet
Variation in the environment can induce different patterns of genetic and phenotypic differentiation among populations. Both neutral processes and selection can influence phenotypic differentiation. Altitudinal phenotypic variation is of particular interest in disentangling the interplay between neutral processes and selection in the dynamics of local adaptation processes but remains little explored. We conducted a common garden experiment to study the phenotypic divergence in larval life-history traits among nine populations of the common toad (Bufo bufo)...
Data from: Tracing the colonization and diversification of the worldwide seabird ectoparasite Ixodes uriaeMuriel Dietrich, Florent Kempf, Thierry Boulinier & Karen D. McCoy
Historical patterns of dispersal and population isolation are key components shaping contemporary genetic diversity across landscapes and require explicit consideration when examining the relative role of different factors in driving the evolution of host specificity in parasitic organisms. In this study, we investigate the worldwide colonisation history of a common ectoparasite of seabirds, the tick Ixodes uriae. This tick has a circumpolar distribution across both hemispheres, but has repeatedly formed host-specific races within different regions....
Populations often experience variable conditions, both in time and space. Here we develop a novel theoretical framework to study the evolution of migration under the influence of spatially and temporally variable selection and genetic drift. First we examine when polymorphism is maintained at a locus under heterogeneous selection, as a function of the pattern of spatial heterogeneity and the migration rate. In a second step, we study how levels of migration evolve under the joint...
Data from: Molecular evolution accompanying functional divergence of duplicated genes along the plant starch biosynthesis pathwayOdrade Nougué, Jonathan Corbi, Steven G. Ball, Domenica Manicacci & Maud I. Tenaillon
Background: Starch is the main source of carbon storage in the Archaeplastida. The Starch Biosynthesis Pathway (SBP) emerged from cytosolic glycogen metabolism shortly after plastid endosymbiosis and was redirected to the plastid stroma during the green lineage divergence. The SBP is a complex network of genes, most of which are members of large multigene families. While some gene duplications occurred in the Archaeplastida ancestor, most were generated during the SBP redirection process, and the remaining...
Data from: Congruent signals of population history but radically different patterns of genetic diversity between mitochondrial and nuclear markers in a mountain lizardAnne-Laure Ferchaud, Rémy Eudeline, Véronique Arnal, Marc Cheylan, Gilles Pottier, Raphaël Leblois & Pierre-Andre Crochet
Historical factors, current population size, population connectivity and selective processes at linked loci contribute to shaping contemporary patterns of neutral genetic diversity. It is now widely acknowledged that nuclear and mitochondrial markers react differently to current demography as well as to past history, so the use of both types of markers is often advocated to gain insight on both historical and contemporary processes. We used 12 microsatellite loci genotyped in 13 populations of a mountain...
Data from: Meteorological conditions influence short-term survival and dispersal in a reinforced bird population.Loïc A. Hardouin, Alexandre Robert, Marie Nevoux, Olivier Gimenez, Frederic Lacroix & Yves Hingrat
A high immediate mortality rate of released animals is an important cause of translocation failure (“release cost”). Post-release dispersal (i.e. the movements from the release site to the first breeding site) has recently been identified as another source of local translocation failure. In spite of their potential effects on conservation program outcomes, little is known about the quantitative effects of these two sources of translocation failure and their interactions with environmental factors and management designs....
All therian mammals have a similar XY/XX sex determination system except for a dozen species. The African pygmy mouse, Mus minutoides, harbors an unconventional system in which all males are XY, and there are three types of females: the usual XX but also XX* and X*Y ones (the asterisk designates a sex reversal mutation on the X chromosome). The long-term evolution of such a system is a paradox, since X*Y females are expected to face...
