古代岩石 wallabies 穿过艰难的地形旅行超过60公里, 新的化石证据显示, 挑战过去的假设和强调人类发展的威胁. Ancient rock wallabies traveled over 60 km across tough terrain, new fossil evidence shows, challenging past assumptions and underscoring threats from human development.

昆士兰州埃特纳山洞穴的化石证据表明,古老的岩壁偶尔会行走60多公里,穿越充满挑战的地形,包括鳄鱼泛滥的河流,这与它们严格定居的信念相悖。 Fossil evidence from Queensland’s Mount Etna Caves reveals that ancient rock wallabies occasionally traveled over 60 kilometers, crossing challenging terrain including crocodile-infested rivers, contradicting the belief that they are strictly sedentary. 对化石化牙齿的同位素分析显示,有些人已经远远超出了出生地,这表明过去的长距离散布有助于保持遗传联系。 Strontium isotope analysis of fossilized teeth shows some individuals moved far beyond their birth sites, suggesting past long-distance dispersal helped maintain genetic connections. 虽然现代岩壁壁一般停留在不到0.2平方公里的范围内,但稀有的雄性分散到8公里以内仍可能支持基因交换。 While modern rock wallabies typically stay within less than 0.2 square kilometers, rare male dispersal up to 8 kilometers may still support genetic exchange. 研究人员警告说,人类发展现在威胁着这些重要的流动模式,突出表明需要制定保护战略,保护地貌连通性,以保护物种的长期生存。 Researchers warn that human development now threatens these vital movement patterns, highlighting the need for conservation strategies that preserve landscape connectivity to protect the species’ long-term survival.
