Relationship of the body fluid concentration of summer and winter Hemigrapsus oregonensis, at 5°, 15° and 25° C., to the medium concentrations after exposure for 48 hours to the experimental salinities. concentration difference at salinities below 100% sea water. For example, at 25% sea water, the absolute difference between 5° and 25° C. was 17% (P = ). As external salinity increased, the difference in blood concentration between low and high temperatures decreased, and a minimum was reached between 100% and 125% sea water for both summer and winter crabs. Above this concentration the difference increased slightly. It should be noted that at the lower salinities (12% to 75% sea water) the highest blood concentration, for winter animals in par- ticular, was found generally at the lowest temperature (5° C.), , as the con- centration of the external sea water decreased, blood concentration increased as temperature Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
