昆士兰东南部的鲨鱼数量因生境损失而暴跌,引起养护问题和潜在的政策变化。 Shark numbers in southeast Queensland plummet due to habitat loss, prompting conservation concerns and potential policy changes.

昆士兰东南部的公牛鲨鱼数量急剧下降,科学家将下降归因于红树林清除造成的生境损失,城市发展扰乱了天然河流口。 Bull shark populations in south-east Queensland have sharply declined, with scientists attributing the drop to habitat loss from mangrove removal and urban development disrupting natural river mouths. 专家警告说,鲨鱼的出现威胁到海洋平衡,可能导致藻类过度增长和珊瑚损害。 Experts warn the absence of sharks threatens marine balance, potentially causing algal overgrowth and coral damage. 尽管没有科学证据表明鲨鱼网减少了攻击风险,但Noosa理事会现在可以试验在鲸鱼迁徙期间去除它们,这表明政策可能有所改变。 Despite no scientific proof that shark nets reduce attack risks, Noosa Council can now trial removing them during whale migrations, signaling a possible policy shift. 这项研究是Noosa生物圈奖决赛,目的是指导今后的养护工作。 The research, a Noosa Biosphere Awards finalist, aims to guide future conservation efforts.
