mammals in Key Largo have discovered a potentially groundbreaking\u2014if not heartbreaking\u2014way to locate and kill invasive Burmese pythons, especially the big ones.<\/p>\n<section class=\"article-banner first-banner ads-336x280\"><!-- \/4988204\/Phys_Story_InText_Box --><br \/>\n      <\/section>\n<p>A team observing raccoon and possum behavior along urban and wilderness fringe of Crocodile National Wildlife Refuge fitted dozens of the mammals with GPS collars, and tracked their locations for months.<\/p>\n<p>In September, about five months into the study, one of the possum collars sent out a mortality signal, triggered by lack of movement\u2014maybe it was hit by a car, maybe a local dog killed it. But then, a few hours later, the collar started moving again.<\/p>\n<p>The researchers had a hunch that the possum suffered a brutal fate.<\/p>\n<p>&#8220;That&#8217;s the signature signal that they got eaten by a snake,&#8221; said Michael Cove, curator of mammals at the North Carolina Museum of Natural <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a>s, one of the partners on the study. He and his research partners from the U.S. Fish &amp; Wildlife Service and Southern Illinois University suspected the snake sat around and digested the possum, and then started moving again.<\/p>\n<p>But even with the tracker, it would take them time to confirm their hunch\u2014Key Largo is essentially a giant fossilized coral reef with a labyrinth of underground pockets and caves. &#8220;This thing was underground. It took a month of tracking the snake underground (to capture it).&#8221;<\/p>\n<p>When they finally yanked it out of the ground, they discovered a 12-foot-long, 66-pound female full of egg follicles. Large females like this can lay close to 100 eggs, and are the holy grail for python hunters. Removing them from the ecosystem is like removing dozens, if not hundreds, of future snakes. The team euthanized her, opened her up and retrieved the collar, which they hope to fit onto another possum soon.<\/p>\n<p>Though the possum&#8217;s demise was grim\u2014pythons coil around their prey, tightening the grip every time the animal exhales, eventually suffocating it\u2014the death proved that wildlife officials can find big pythons by tracking their prey.<\/p>\n<p>Cove and his research partners hope the method can help control the explosive population growth of the invasive snake, which has decimated ecosystems in South Florida for decades. Indigenous to southeast Asia, Burmese pythons likely slithered their way into the Everglades in the 1990s via the exotic pet trade.<\/p>\n<p>They&#8217;ve thrived, establishing breeding populations as far south as Key Largo and as far north at the Loxahatchee National Wildlife Refuge in western Palm Beach County.<\/p>\n<p>Cove said that the problem is so severe in Everglades National Park that &#8220;there are no more mammals to put these collars on.&#8221; The largest invasive python ever recorded in Florida was 18 feet long.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Proof_of_concept_and_a_glitch\"><\/span>Proof of concept, and a glitch<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The study occurred on the boundary between the human world and wilderness, and looked at what h<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>ens when raccoons and possums are &#8220;dumpster diving and eating all the cat food that people put out for them instead of eating the native seeds and fruits,&#8221; Cove said.<\/p>\n<p>Both species consume a lot of native fruits and defecate the seeds out in different areas, becoming important seed dispersers.<\/p>\n<p>A parallel goal, though, was to learn more about pythons if the mammals were eaten.<\/p>\n<p>&#8220;If we could catch a snake in the act, it could lead to management and removal of the pythons,&#8221; Cove said.<\/p>\n<p>The first possum was proof of concept\u2014the collar survived the crush of the snake, and the snake didn&#8217;t pass the collar, giving the scientists time to find it.<\/p>\n<p>Two weeks ago, a second collar stopped moving, then started again, indicating that a big raccoon had been eaten by a snake. This time they found the snake more quickly: jackpot, a 77-pound behemoth also full of egg follicles.<\/p>\n<p>On Wednesday, yet another collar emitted a mortality signal and started moving again. But by the time researchers reached the tracker, all they found was a collar in a pile of snake poop; the python had passed the device.<\/p>\n<p>&#8220;This was really crushing to me that we didn&#8217;t pull out this giant monster snake that ate this latest opossum,&#8221; Cove said. They now know that there&#8217;s a sense of urgency, especially if the snake is large enough to pass the collar.<\/p>\n<p>Of the 43 collars they&#8217;ve deployed, they know three were ingested by pythons, but six more have simply disappeared. The research team now wonders if they were consumed by pythons who then moved beyond the study&#8217;s geographic range.\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Cruel_or_crucial\"><\/span>Cruel or crucial?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Is tracking prey to find pythons tantamount to using innocent raccoons and possums as bait?<\/p>\n<p>&#8220;That&#8217;s a question we&#8217;re getting\u2014don&#8217;t you feel guilty for putting these animals at risk?&#8221; Cove said.<\/p>\n<p>He said the collared animals are not at greater risk, they go about their business as they normally would, and researchers ensure the collars don&#8217;t hinder their movements. Unfortunately the pythons sometimes intercept them.<\/p>\n<p>&#8220;We&#8217;re not doing anything but observing the animals doing their natural thing, and they&#8217;re unfortunately getting consumed and it&#8217;s leading to these python removals,&#8221; he said.<\/p>\n<p>As it stands, no one has invented an effective way to remove invasive pythons.<\/p>\n<p>Authorities have tried myriad methods, including tracking them with beagles, holding a python-catching derby called Python Challenge\u2014last year&#8217;s 10-day challenge resulted in 231 snakes killed, a small fraction of the &#8220;tens of thousands&#8221; the U.S. Geological Survey estimates are lurking wild in the state.\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Will_tracking_pythons_with_their_prey_eradicate_the_destructive_serpents\"><\/span>Will tracking pythons with their prey eradicate the destructive serpents?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>No, but it has an advantage over other methods that might make it more potent.<\/p>\n<p>&#8220;The beauty of this project is that there are size limitations to the snakes,&#8221; Cove said. &#8220;These are big racoons and larger male opossums, so big snakes that are taking these\u2014the largest snakes are big females.&#8221;\n<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_next_step\"><\/span>The next step<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The research collaborators at Crocodile Lake National Wildlife Refuge are currently putting together proposals with stakeholders in South Florida to find ways to fund and create more and cheaper collars for further study.<\/p>\n<p>Cove said researchers are working on building collars that are small and light enough to not impede the raccoons and possums who wear them, but large enough to prevent the big target snakes from passing them. One idea is to cinch zip ties on the collars so that the plastic tails catch within the snake&#8217;s digestive tract.<\/p>\n<p>Additionally, if future collars don&#8217;t need to track mammal movement, but merely signal mortality and location, they can be much cheaper. Current collars cost $1,500 and work for two years. But simpler mortality VHS collars would come in at about $200 each.<\/p>\n<p>&#8220;If we can make cheaper collars and incorporate drone <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a> \u2026 we could put this out on a much broader scale,&#8221; Cove said. &#8220;This could be another tool. We need everything that we can find to remove as many pythons as possible.&#8221;<\/p>\n<p class=\"article-main__note mt-4\">\n                                                  2023 South Florida Sun-Sentinel.<\/p>\n<p>Distributed by Tribune Content Agency, LLC.<\/p>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                <strong>Citation<\/strong>:<br \/>\n                                                As pythons in Florida try to hide, they face a new enemy: Possums with GPS collars (2023, February 13)<br \/>\n                                                retrieved 13 February 2023<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>\/2023-02-pythons-florida-enemy-possums-gps.html<\/p>\n<p>                                             This document is subject to copyright.
