Deforestation, typhoons and landslides can all fragment forests, making it difficult for primates to navigate their environment like usual. <br><br><br><br><br>CNET Science <br><br><br><br><br>From the lab to your inbox.

And while larger males were able to leap over widely spaced trees, that method proved risky for hesitant pregnant females or those carrying infants. <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>Now playing:<br>Watch this:<br><br>Watch an endangered primate cross a rope bridge like...<br><br><br><br><br><br><br>0:34<br><br><br><br><br><br>Once the simple canopy bridge was in place at the Hainan Bawangling National Nature Reserve, photographs showed it took the gibbons a little over six months to begin crossing it, gradually increasing its use in the following years. Adult females initiated half the crossings, and juveniles tackled the other half. Most gibbons got across by "handrailing" -- walking on one rope with hands holding the second rope as handrails, or climbing underneath the ropes legs first with all limbs. <br><br>At least one brazen beast walked it like a tightrope. <br><br>The ape version of Philippe Petit. <br><br>Kadoorie Farm and Botanic Garden<br><br>Various types of artificial crossings have helped wildlife traverse ruptured forest canopies before, but the study in Scientific Reports documents the first one constructed for the Hainan gibbon, a species endemic to China's Hainan Island and [https://www.kynghidongduong.vn/tours/du-lich-trung-quoc-gia-re/ kynghidongduong.vn] known for [https://www.kynghidongduong.vn/tours/du-lich-trung-quoc-gia-re/ tour trung quoc] singing to mark territory, enhance bonding and attract mates. <br><br>"Over 2,000 individuals were estimated to live throughout the island in the 1950s, but due to rampant poaching and forest loss, the population declined sharply to less than 10 individuals in the 1970s" before a determined effort got the number up to 30, Kadoorie Farm and Botanic Garden says. <br><br>As of 2020, the Hainan is the only gibbon species assessed by the [ International Union for Conservation of Nature Red List of Threatened Species] to have a stable population, according to Kadoorie, adding "all 19 other species are decreasing in numbers." <br><br>The researchers consider the canopy bridge, [https://www.kynghidongduong.vn/tours/du-lich-trung-quoc-gia-re/ tour trung quốc giá rẻ] while promising, a temporary solution.
