摘要

海岛特有的生物群十分脆弱,许多已经消失。更古老、更复杂、更具活力的大陆生物群更有弹性,但现在正在被毁灭。苏门答腊岛和马达加斯加岛是大型大陆板块岛屿,具有非常不同的历史和生物群,这体现了大陆地块的情况。由于人口压力,这两个热带岛屿都遭受了巨大的栖息地丧失和物种灭绝,苏门答腊岛主要受到全球压力,马达加斯加岛则受到当地压力。蜗牛展示了动物起源的复杂历史,马达加斯加、印度和东南亚蜗牛动物群与其板块构造地质史之间的关系就说明了这一点。蜗牛也揭示了我们对细节的有限了解,但没有揭示栖息地丧失导致物种灭绝的范围。国际机构未能解决自然栖息地丧失和随之而来的物种灭绝的根本原因,即人口过剩和建立在永久增长基础上的经济体系。论述了可持续发展的谬论和当前保护实践的局限性。认识到我们无法在不久的将来阻止物种灭绝,需要在分子技术进步的基础上采取一种新的、补充性的保护方法。

tale of two islands. The reality of large-scale extinction in the early stages of the Anthropocene: a lack of awareness and appropriate action
The endemic biotas of oceanic islands were vulnerable and many have been lost. The more ancient, complex and dynamic biotas of continents were more resilient but are now being obliterated. Sumatra and Madagascar are large continental plate islands with very different histories and biotas that exemplify the situation on continental land masses. Both tropical islands have suffered massive habitat loss and species extinction from human population pressure, Sumatra mostly from global and Madagascar from local pressure. Snails demonstrate the complex history of faunal origins as illustrated by the relationships between Madagascan, Indian and southeast Asian snail faunas and their plate tectonic geological history. Snails also reveal our limited knowledge of the details but not the scope of extinctions through habitat loss. International agencies are failing to address the root causes of natural habitat loss and consequent extinctions, which are overpopulation and an economic system based on perpetual growth. The fallacy of sustainable development and the limitations of current conservation practice are addressed. Recognition that we cannot stop extinctions in the immediate future demands a new, supplementary approach to conservation based on advances in molecular technology.
