Some cope better than others Increasingly, research is revealing how organisms may, or may not, adapt to a changing climate. Understanding the limitations placed by species's physiology can help determine whether it has an immediate potential deal with rapid change. Many studies have looked at physiological tolerance climate change in fishes, results indicating range of responses. Dahlke et al. conducted meta-analysis explore life stage influence ability tolerate temperature (see Perspective Sunday). They found that embryos and breeding adult fishes are much more susceptible those other stages this factor must therefore be considered evaluations susceptibility. Science , issue p. 65 ; see also 35
