Isolation and characterization of microsatellite loci in two non-native hydromedusae in the San Francisco Estuary: Maeotias marginata and Moerisia sp.

We characterized 10 new microsatellite markers in each of two species of hydromedusae, Maeotias marginata and Moerisia sp. Genetic diversity was estimated using 20–41 individuals collected from Suisun Marsh within the San Francisco Estuary, CA. Allelic richness ranged from 5–9 in M. marginata and 2–10 in Moerisia sp. with average expected heterozygosities of 0.71 and 0.57 respectively. One locus in M. marginata and two in Moerisia sp. deviated from Hardy–Weinberg equilibrium expectations, likely due to null alleles

Modeled relationships between growth and temperature.

<p>Solid line represents the predicted Michaelis-Menten relationship between temperature and growth rate. Dashed line shows the predicted linear relationship between temperature and growth rate. Shaded areas demonstrate the 5^th and 95^th percent confidence interval for the predicted relationships. Circles show the observed data points. Increased darkness of circle shading corresponds with the number of data points at that location. Circles falling below 0.00 on the y-axis represent polyps that died (i.e., negative growth).</p
