Male mosquitoes sing from the same song sheet.

physiological and biochemical strategies to live at stable, sub-zero temperatures; however, evidence suggests low temperatures may place constraints on protein homeostasis. Todgham et al. (pp. 369–378) examined the ubiquitin–proteasome protein degradation pathway in two species of Antarctic fish compared with their temperate New Zealand relatives to better understand temperature compensation of a key pathway involved in the maintenance of protein integrity at sub-zero temperatures.
