Because cold-blooded animals rely on the thermal conditions of their environment to regulate their body temperature, they&#8217;re expected to need more energy as the planet warms.<\/p>\n<p>However, our new research, published today in <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/s41558-023-01607-6\"><i>Nature Climate Change<\/i><\/a>, suggests temperature is not the only environmental factor affecting the future energy needs of cold-blooded animals. How they interact with other species will also play a role.<\/p>\n<p>Our findings suggest cold-blooded animals will need even more energy in a warmer world than previously thought. This may increase their extinction risk.\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_we_already_know\"><\/span>What we already know <span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The amount of energy animals use in a given amount of time is called their metabolic rate.<\/p>\n<p>Metabolic rate is influenced by a variety of factors, including body size and activity levels. Larger animals have higher metabolic rates than smaller animals, and active animals have higher metabolic rates than inactive animals.<\/p>\n<p>Metabolic rate also depends on body temperature. This is because temperature affects the rate at which the biochemical reactions involved in energy metabolism proceed. <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">General<\/a>ly, if an animal&#8217;s body temperature increases, its metabolic rate will <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.science.org\/doi\/10.1126\/science.1061967\">accelerate exponentially<\/a>.<\/p>\n<p>Most animals alive today are cold-blooded, or &#8220;ectotherms&#8221;.

But this prediction doesn&#8217;t account for the animals&#8217; capacity to physiologically &#8220;acclimate&#8221; to warmer temperatures.<\/p>\n<p>Acclimation refers to an animal&#8217;s ability to remodel its physiology to cope with a change in its environment.<\/p>\n<p>But rarely can acclimation fully negate the effect of temperature on metabolic processes. For this reason, by the end of the century land-based ectotherms are still predicted to have metabolic rates about <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/nclimate2457\">20% to 30%<\/a> higher than they are now.<\/p>\n<p>Having a higher metabolic rate means that animals will need more food. This means they might starve if more food is not available, and leaves them less energy to find a mate and reproduce.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Our_research\"><\/span>Our research <span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Previous research attempts to understand the energetic costs of climate warming for ectotherms were limited in one important respect. They predominantly used animals studied in relatively simple laboratory environments where the only challenge they faced was a change in temperature.<\/p>\n<p>However, animals face many other challenges in nature. This includes interacting with other species, such as competing for food and predator-prey relationships.<\/p>\n<p>Even though species interact all the time in nature, we <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1002\/evl3.174\">rarely study<\/a> how this affects metabolic rates.<\/p>\n<p>We wanted to examine how species interactions might alter predictions about the energetic costs of climate warming for cold-blooded animals. To do this, we turned to the fruit fly (from the genus Drosophila).<\/p>\n<p>Fruit fly species <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.journals.uchicago.edu\/doi\/abs\/10.1086\/284277\">lay their eggs<\/a> in rotting plant material. The larvae that hatch from these eggs <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.jstor.org\/stable\/3547007?seq=2\">interact<\/a> and compete for food.<\/p>\n<p>Our study involved rearing fruit fly species alone or together at different temperatures. We found when two species of fruit fly larvae compete for food at warmer temperatures, they were more active as adults than adults that didn&#8217;t compete with other species as larvae. This means they also used more energy.<\/p>\n<p>From this, we used modeling to deduce that species interactions at warmer global temperatures increase the future energy needs of fruit flies by between 3% and 16%.<\/p>\n<p>These findings suggest previous studies have underestimated the energetic cost of climate warming for ectotherms.
