Abstract
The Effect of Salinity Acclimation on the Upper Thermal Tolerance Threshold of the European Green Crab
Highlights
Ecophysiological research has historically focused on altering one abiotic variable at a time to measure the physiological response to that variable
Along the west coast of North America, the estuarine distribution of Carcinus maenas has been attributed to predation by a larger, aggressive native crab Hunt & Yamada [5]
The three salinity treatments differed in their mean critical thermal maxima (CTmax) values (Figure 1, Table 1, Analysis of Covariance (ANCOVA), F(2,42) = 4.16, P = 0.02)
Summary
Ecophysiological research has historically focused on altering one abiotic variable at a time to measure the physiological response to that variable. Nagaraj [6] found that salinity had little to no effect on developmental rates of C. maenas; zoeae kept in high salinity treatments (25 and 35ppt) had the greatest survival rates at the lowest experimental temperature, ~10 °C [6]. While these studies are informative, they do not necessarily reflect the dynamic abiotic environment that C. maenas inhabits
