These three studies investigated the effects of climate change, and in particular increased temperatures in intertidal zones. The study conducted by Bertness et al worked to quantify thermal stresses on rocky intertidal organisms. The species that was focused on was Semibalanus balanoides at sites north and south of Cape Cod. The team analyzed the relationship between thermal stress, population density and individual organism survival rates. While the study conducted by Bertness focused on increases in environmental temperatures, the study conducted by Helmuth and his team investigated the effect of increased global temperatures on the body temperatures of organisms, which is ultimately capable of altering their physiological activities and functioning. The team used a heat budget model to collect data in relation to mussel body temperature at three different tidal elevations along the coast of California, all of which are also exposed to different ambient temperatures, light intensity, wind patterns, waves, and tide timing. The study conducted by Barry et al also investigated intertidal communities, but focused on the range shifts of intertidal species between 1931 and 1933, as well as 1993 and 1994. It was noted that species shifted their ranges northward, which is consistent with global warming models and other studies that have observed range shifts in recent years. Forty-five species were investigated within California intertidal communities. Along with this presented
