Northern Bahamian rock iguanas (Cyclura cychlura), already noted as vulnerable on the International Union for Conservation of Natures Red List, face a serious brand-new hazard: adoring travelers who frequently provide them grapes as if theyre paying tribute to Dionysus, the Greek god of wine.Research released today (April 21) in the Journal of Experimental Biology shows that iguanas that live on islands frequented by grape-slinging tourists are not able to manage their blood glucose levels as well as those that live on more remote islands to which human beings hardly ever venture. “Theyre simply little garbage trucks,” states Taylor, who didnt work on the brand-new study.On a 2019 exploration, California Polytechnic State University physiological ecologist Emily Taylor experienced a traveler feeding an iguana lettuce that she was holding from her mouth, risking the lizards ferocious bite.EMILY TAYLORStudy coauthor Charles Knapp, vice president of conservation research study at the John C. Shedd Aquarium, states the simple noise of a boat engine draws the iguanas to coast, adding that the reptiles used to be scared of people to the point that they were hard to spot before tourists began visiting.Ecologists are well familiarized with the impacts that human ecotourism has on iguanas. The brand-new research study assists paint a more complete picture of how ecotourism impacts iguanas by focusing on their metabolism.In the laboratory, researchers fed green iguanas (Iguana iguana) a glucose-rich diet for 17 days, then measured their blood sugar levels throughout a glucose tolerance test.
