Jaime Rojo: 帝王蝶的迁徙是北美最具标志性的自然奇观之一,也是生态系统健康的重要指标。然而,过去40年来,帝王蝶的数量持续下降,这反映了我们与自然世界关系的变迁。帝王蝶的迁徙需要三到五代才能完成,旅程跨越数千英里,途中面临诸多挑战。科学家们仍在研究帝王蝶如何精准地找到其越冬地,目前有几种假说,但确切机制尚不清楚。 帝王蝶面临的主要威胁包括栖息地丧失,特别是草原的减少和转化为农业用地。20世纪90年代,除草剂和转基因作物的广泛使用导致乳草(帝王蝶的寄主植物)大量消失,进一步加剧了种群下降。此外,道路交通事故、城市灯光污染以及气候变化(干旱、热浪、暴风雪)也对帝王蝶造成了严重威胁。 尽管挑战重重,但保护帝王蝶的努力也在积极进行。与墨西哥当地社区合作,控制森林砍伐率至关重要。农民与环保主义者合作,利用无人机寻找乳草,恢复帝王蝶的栖息地。沿迁徙路线,许多人正在将他们的后院变成帝王蝶的栖息地,为帝王蝶提供食物和休息场所。农民种植的草原带也对帝王蝶的生存有益。 帝王蝶的故事可以激励人们,促进团结,并让人们重新与自然世界连接。保护帝王蝶的行动正在兴起,但需要立即采取行动,以避免失去这一标志性物种。

  • Monarch butterflies undertake a multi-generational migration.
  • The migration starts in Mexico and spans thousands of miles.
  • How monarchs navigate to the same locations remains a mystery.

Shownotes Transcript

When monarch butterflies migrate, they produce one of the most iconic wildlife spectacles in the world — and provide us with an important indicator of ecological health, says photographer Jaime Rojo. Telling a story about our relationship to the natural world, he shares his experience photographing these mesmerizing insects deep in their remote mountain habitats in Mexico, diving into the latest research into the mysteries of their multi-thousand-mile journey and sharing how each of us can join the growing movement to protect them.
