Pecten-Msat-Genotypes

File: Pecten-Msat-Genotype.xls Contain all the data in excel formating, ready to be converted by a software such as CREATE (Coombs et al. 2008) First sheet ("genotype_raw"): raw data (all individuals genotyped at all microsatellite loci) Each line is an individual animal.Each columns after population and individual identifier contain one allele. Both alleles for a given locus are given consecutively (see header row). For details on microatellites primers, PCR protocols and marker statistics please see Morvezen et al. 2013 and Morvezen et al. 2016 Population names are abbreviated in the publication for simplicity. Name equivalences Hatch=Hatchery=H Wild=W Second sheet ("genotypes_cleaned") Same as the first sheet minus indivudals with >50% missing data. This is the dataset used as input for all analyses in the publication

Effective population size.

<p>For different number of available mates, , and probability that two eggs are fertilised by the same sperm package, , we show the ratio of the effective population size () to the total population size (). Parameters: , .</p

Spatial structure of the marine habitats of <i>Littorina saxatilis</i>.

<p>(<b>A</b>) A schematic illustration of the geographical structure of populations with mainland (red), islands (green), and skerries (blue). (<b>B</b>) Principal components of allozyme population differentiation in <i>L. saxatilis</i> (data from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0075587#pone.0075587-Janson1" target="_blank">[13]</a>, the presumably selected locus is excluded). Populations are classified as mainlands (red), islands (green), or skerries (blue). (<b>C</b>) Stepping-stone model of a section of the archipelago, with the mainland (labelled by ) acting as a source for establishing the island populations ( to ). On average, each island sends females per generation to its right and to its left neighbouring island (but, note that the mainland and the island furthest from the mainland have only one neighbour).</p

Distribution of number of progeny attributed to each sire.

<p>Bars in panel <b>A</b> show the empirical data obtained under experimental conditions; the data correspond to six broods, two of which have size , and the remaining four have sizes , , , and . Bars in panel <b>B</b> show the results from females mated in the field, data taken from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0075587#pone.0075587-Panova1" target="_blank">[10]</a>; the data correspond to four broods of sizes , , , and . The width of the bins are chosen so that the expected number of counts in each bin is not smaller than . The probability assigned to each bar is proportional to the bar area. Symbols and error bars show the result of the best fit to the experimental data, together with their 95% confidence intervals: in (<b>A</b>), and in (<b>B</b>). We simulated independent realisations of the mating process.</p

Temporal fluctuations of heterozygosity.

<p>(<b>A</b>) Heterozygosity as a function of distance from the mainland and of time (single realisation of the model described). Mainland is not shown. The data correspond to generations after the initial generations. The number of available mates is . (<b>B</b>) Analytically computed durations of low-and high-heterozygosity phases (blue, and red) relative to their corresponding values for . (<b>C</b>) Analytically computed steady-state heterozygosity (black) relative to its corresponding value for . Remaining parameters are as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0075587#pone-0075587-g004" target="_blank">Fig. 4 <b>C</b></a>.</p

Analytically computed heterozygosity during colonisation and in the steady state.

<p>(<b>A</b>) Heterozygosity during colonisation as a function of distance from the mainland. The lines shown from top to bottom correspond to: , , , , and . (<b>B</b>) Heterozygosity during colonisation relative to its corresponding value for as a function of distance from the mainland. The order of lines corresponds to that in <b>A</b>. (<b>C</b>) and (<b>D</b>) Same as in (<b>A</b>) and (<b>B</b>), respectively, but for the steady state. Remaining parameters: all available males are on average equally successful, , the mainland heterozygosity is set to unity, the scaled female migration rate is , the number of females in each populated island is , the probability that two eggs are fertilised by the same sperm package is , and the number of islands is .</p

Relationships between the mean annual sea surface temperature and the growth performance index (Φ′).

<p>This index issued from the Arrhenius model was given for populations sampled in (1) Vigo, (2) Ile de Re, (3) Bay of Brest, (4) Bay of Seine, (5) Plymouth, (6) Holyhead, (7) Scarborough, (8) Campbell Town, (9) Austevoll, (10) Bessaker, (11) Bronnoysund, and (12) Traena.</p

Summary growth data.

<p>Von Bertalanffy growth parameters and index of growth performance (Φ′) were fitted from growth data of each study station (in brackets, the limits of the asymptotic 95% confidence interval). Maximum daily growth, MDG (in µm d⁻¹), was averaged on the ten highest successive increments (± standard error).</p

Relationships between the mean annual sea surface temperature and the daily growth parameters.

<p>This is shown for A) the maximum numbers of growth days (MNG); and B) the variation in the number of growth days with increasing age (Ω in d y⁻¹) for populations sampled in (1) Vigo, (2) Ile de Re, (3) Bay of Brest, (4) Bay of Seine, (5) Plymouth, (6) Holyhead, (7) Scarborough, (8) Campbell Town, (9) Austevoll, (10) Bessaker, (11) Bronnoysund, and (12) Traena.</p

Variation in mean daily shell growth throughout life (black line) for each sampled population.

<p>Gray vertical bars represent the 95% confidence interval of each mean value. The numbers in each graph indicate the annual number of growth days.
