Figure 4. Hsp70 expression in zebra mussels infected or not by macroparasites.

Hsp 70 expression (Surface density, Sv) in each experimental group of the macroparasite studies. (A) Comparison of non-infected vs P. folium-infected zebra mussels, males or females. (B) Comparison of non-infected vs B. polymorphus-infected zebra mussels. Center lines show the median, 25^th-75^th percentile (within box), minimum/maximum value (error bar). The small circles represent atypical values and the stars the extreme values.
