But often these elaborate strategies come at a cost. For example, looking out for and fleeing from predators involves a great deal of cognitive capacity and energy. Camouflage, on the other hand, may complicate the animals&#8217; search for mates, and it largely limits their freedom of movement to the matching background.<\/p>\n<section class=\"article-banner first-banner ads-336x280\">\n         <!-- \/4988204\/Phys_Story_InText_Box --><\/p>\n<\/section>\n<p>University of Zurich (UZH) evolutionary biologist Stefan L\u00fcpold and researchers from China and the Netherlands have now investigated how frogs have adapted to these conflicting selection pressures. Their study is published in <i><a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a> Advances<\/i>.<\/p>\n<p><b>Large brains and flight vs. small brains and camouflage<\/b><\/p>\n<p>The team studied the evolution of anti-predator adaptation in over 100 species of frogs. Their findings indicate that frogs with few predators may rely on escape strategies to survive. Their relatively large brains allow for a flexible flight response, and their muscular hindlegs take them leaps away from their predators. These frogs can afford to be conspicuously colored, facilitating their visual communication.<\/p>\n<p>When frogs are faced with many predators, however, fleeing becomes less efficient, as it takes valuable time away from searching for food or mates. <\/p>\n<p>&#8220;Under these unfavorable conditions, the cognitive costs needed for this strategy outweigh its benefits,&#8221; says last author Stefan L\u00fcpold. &#8220;Here, evolution has led to a gradual shift from cognitive predator evasion to camouflage\u2014and thus smaller brains.&#8221;<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/frogs-use-brains-or-ca-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/frogs-use-brains-or-ca-1.jpg\" data-sub-html=\"Hyla annectans wulingensis.

It suggests that camouflage isn&#8217;t necessarily an ideal primary strategy, as is often believed, but may be a secondary adaptation when the energetic costs of cognitive predator evasion become too high. Further research is needed to determine if such links also <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>ly to other strategies in frogs (e.g., poison glands), or if they exist in other animal species.<\/p>\n<p>&#8220;Our study highlights that research on brain evolution has to consider metabolic costs as much as it focuses on cognitive benefits,&#8221; explains Stefan L\u00fcpold. If high predation pressure leads to behavioral changes and smaller brains, it may also substantially impact other vital functions. The study further suggests that changing the habitat of prey can alter their energetic investments.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Scientists use robots to reveal how predatory fish cope with unpredictable prey\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Wen Bo Liao, Cognition contra camouflage: How the brain <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/social-mediaa\/\" data-internallinksmanager029f6b8e52c=\"1\" title=\"Social Media\" target=\"_blank\" rel=\"noopener\">media<\/a>tes predator-driven crypsis evolution, <i>Science Advances<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1126\/sciadv.abq1878\">DOI: 10.1126\/sciadv.abq1878<\/a>. <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.abq1878\">www.science.org\/doi\/10.1126\/sciadv.abq1878<\/a><\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    University of Zurich<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.uzh.ch\/\"><br \/>\n                                                        <svg>\n                                                            <use href=\"https:\/\/phys.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n                                                        <\/svg><br \/>\n                                                    <\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Frogs use brains or camouflage to evade predators (2022, August 17)<br \/>\n                                                 retrieved 17 August 2022<br \/>\n                                                 from https:\/\/phys.org\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-08-frogs-brains-camouflage-evade-predators.html<\/p>\n<p>                                            This document is subject to copyright.
