Bult\u00e9 studies northern map turtles, whose females can grow to twice the length of males. He wondered whether males might be attracted to larger females, but the turtles\u2019 skittish nature\u2014and the fact that they mate on the floor of the lake\u2014made observation tricky.<\/p>\n<p>Bult\u00e9\u2019s team printed two 3D models of female turtles, identical in every aspect except size, and placed them a meter apart on the lakebed, with cameras rigged up to record how wild males reacted.<\/p>\n<\/div>\n<p><strong>Watch\u00a0male and female northern map turtles interacting with 3D printed decoys in the field:<\/strong><\/p>\n<p><strong><a href=\"https:\/\/youtu.be\/MagFMhLjelw\">Studying turtle&#8217;s reproduction with sex dolls and gopros<\/a><\/strong><\/p>\n<\/div>\n<header class=\"article__header article__header--inline\"><\/header>\n<p><\/p>\n<p>The Biology Team consisted of:<\/p>\n<ul>\n<li><a href=\"https:\/\/carleton.ca\/biology\/people\/ed-bruggink\/\">Ed Bruggink<\/a><\/li>\n<li><a href=\"https:\/\/carleton.ca\/biology\/people\/gregory-bulte\/\">Gr\u00e9gory Bult\u00e9<\/a><\/li>\n<li><a href=\"https:\/\/carleton.ca\/biology\/people\/ryan-chlebak\/\">Ryan Chlebak<\/a><\/li>\n<li><a href=\"https:\/\/carleton.ca\/biology\/people\/jeff-dawson\/\">Jeff Dawson<\/a><\/li>\n<\/ul>\n<p><\/p>\n<p><strong>See full article here:<\/strong><\/p>\n<p><strong><a href=\"http:\/\/www.sciencemag.org\/news\/2018\/04\/here-s-what-happens-when-you-replace-toads-and-turtles-3d-printed-replicas-wild\">Here\u2019s what happens when you replace toads and turtles with 3D-printed replicas in the wild<\/a><\/strong><br \/>\n<strong>By Matt Warren<\/strong><\/p>\n<p><\/p>\n<\/div>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>Carleton University Biology Team addresses male turtle mating preferences with 3D-printed replica turtles When the first rains arrive in the forests of northwest Costa Rica, yellow toads gather in the hundreds for an intense but short-lived breeding season.
