The study is <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/zslpublications.onlinelibrary.wiley.com\/doi\/10.1111\/acv.12978\">published<\/a> in <i>Animal Conservation<\/i>.<\/p>\n<p>                                                                                    Marine Mammal Research Program (MMRP) researchers are comparing the drone imagery results with long-term data and data from stable, non-endangered bottlenose dolphin populations in Shark Bay, Australia, and Sarasota Bay, Florida.<\/p>\n<p>&#8220;In [our new] study, we highlight the speed and accuracy of UAS-photogrammetry (drone imagery) in assessing the age structure of free-ranging dolphin populations, and the implications towards management and conservation,&#8221; said Fabien Vivier, MMRP researcher and lead author of the study.<\/p>\n<p>&#8220;Our hope is that by using this method, we can quickly monitor the age-structure of free-ranging dolphin populations. This information can facilitate the detection of early signs of population changes, such as a decrease in the number of calves, and provide important insights for timely management decisions.&#8221;<\/p>\n<p>Healthy dolphin populations have a consistent proportion of calves, juveniles and adults; a deviation from this can suggest the population is unstable. Using drones, researchers were able to quickly quantify the age-structure of the critically endangered dolphin population in Greece in a few days.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Previous_study_classifies_dolphin_age\"><\/span>Previous study classifies dolphin age<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In a previous study, the MMRP team used specialized calibrated drones to successfully measure the length of free-swimming dolphins and classify them by age.<\/p>\n<p>&#8220;When dolphins come to the surface to breathe, they expose their blowhole and dorsal fin,&#8221; said Vivier. &#8220;By measuring the distance between the two, we can estimate their total body length. Since total length is related to age, we can estimate the age-group of a single dolphin.&#8221;<\/p>\n<p>Aquatic mammals known as cetaceans, which include whales, dolphins and porpoises, face a slough of threats from habitat degradation, climate change, fisheries, and chemical and noise pollution. One quarter of the 92 known cetacean species are at risk of extinction, and there is a clear and urgent need to implement effective conservation strategies.<\/p>\n<p>The project was done in collaboration with the Shark Bay Dolphin Research Project and the Sarasota Dolphin Research Program.<\/p>\n<div class=\"article-main__more p-4\">\n                                                                                        <strong>More information:<\/strong><br \/>\n                                                F.
