Antarctic icefish do not tolerate rising temperatures


Antarctic finfishes may be facing rising ocean temperatures. This is of particular concern to icefishes, as they are not very tolerant of increasing temperatures. Prior studies have shown that this lack of tolerance may be due to an inability for their hearts to beat normally and actually collapse at higher temperatures. In a study presented at the 34th annual Ohio Physiological meeting at Wright State University today, researchers Evans et al., (working under the direction of Dr. Elizabeth Crockett at Ohio University) examined biochemical differences in the heart muscle cells that appear to explain their lack of tolerance.
