AFLP data for field collected marine bivalves in shallow intertidal locations in NW Europe. The species is Macoma balthica, the Baltic clam. Please refer to the original publication for further information such as exact locations and local habitat characteristics. File contains data on 644 individuals from 21 different locations scored (presence/absence) for 90 AFLP markers

Boxplots of <i>Mytilicola orientalis</i> body length (μm) in both host species.

<p>Female (left) and male (right) copepods originating from oysters (<i>Magallana gigas</i>) in grey and from mussel (<i>Mytilus edulis</i>) hosts in white, from the Dutch Delta and Wadden Sea. The boxes represent the interquartile range, the whiskers denote the lowest and highest values within the 1.5 interquartile range, the black line in each box denotes the median, the large black dots represent the mean and the smaller dots outside the boxes are outliers.</p

Parasite body length (corrected for host size using linear regression) for both introduced <i>Mytilicola</i> species.

<p><b>Females (left) and males (right) of</b><i>M</i>. <i>intestinalis</i> (grey) and <i>M</i>. <i>orientalis</i> (white) in each surveyed region. The boxes represent the interquartile range, the whiskers denote the lowest and highest values within the 1.5 interquartile range, the black line in each box denotes the median, the large black dots represent the mean and the smaller dots outside the boxes are outliers.</p

Relationship between host shell length (mm) and parasite body length (μm) per sex for each <i>Mytilicola</i>-host species combination.

<p>(A) <i>M</i>. <i>orientalis</i> in blue mussels (<i>Mytilus edulis</i>). (B) <i>M</i>. <i>intestinalis</i> in blue mussels. (C) <i>M</i>. <i>orientalis</i> in Pacific oysters (<i>Magallana gigas</i>). Fitted lines are significant regressions.</p

Schematic representation (not to scale) of both sexes of both introduced <i>Mytilicola</i> species.

<p>On the left both sexes of <i>M</i>. <i>intestinalis</i> and on the right both sexes of <i>M</i>. <i>orientalis</i>, all viewed from the ventral side, with indications of the body size measurements that were taken. Note the dorsolateral thoracic protuberances which are folded inwards in <i>M</i>. <i>intestinalis</i> and extended outwards in <i>M</i>. <i>orientalis</i>. For detailed drawings see original species descriptions, including views from other sides and close-ups [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0193354#pone.0193354.ref015" target="_blank">15</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0193354#pone.0193354.ref023" target="_blank">23</a>].

Discriminant distributions of <i>Mytilicola</i> for each sex separately.

<p>(A) Females (n = 92) and (B) males (n = 90) of the parasitic copepods <i>M</i>. <i>intestinalis</i> (grey) and <i>M</i>. <i>orientalis</i> (white). The x-axis is the discriminant score of the first discriminant function and the y-axis is the relative frequency of the observations. The light grey area indicates “mistaken” assignments in comparison with molecular identifications.</p

Sampling locations of blue mussel (<i>Mytilus edulis</i>) and Pacific oyster (<i>Magallana</i> (previously <i>Crassostrea</i>) <i>gigas</i>) hosts.

<p>Left: The sampled regions in the Dutch Delta and the Wadden Sea (shaded area), with the islands Sylt (north) and Texel (south). Above right: Sampling locations around the islands of Sylt and Texel in the Wadden Sea. Below right: Sampling locations in the Dutch Delta.

Principal component analysis of <i>Mytilicola</i> for each sex separately.

<p>(A) Females (n = 92; seven morphological variables). (B) Males (n = 90, six variables). In grey, individual parasites that were molecularly identified as <i>M</i>. <i>intestinalis</i>; in black, similarly identified <i>M</i>. <i>orientalis</i> (gds = length of the genital double-somite; acr = angle between caudal rami and anteroposterior axis).</p
