Sebastian Echeverri 讲述了气味对人类和动物的吸引力，例如新鲜出炉的面包的气味会让人们不由自主地被吸引。他还提到了动物利用气味寻找食物和同伴。Rutendo Shackleton 则介绍了大象利用低频隆隆声进行远距离通讯，保持群体联系的现象。Pauline Fleischmann 描述了沙漠蚂蚁在生命早期利用地球磁场进行导航，以及他们团队如何通过实验验证这一发现。Steve Simpson 详细解释了健康珊瑚礁的独特声景，以及声音在珊瑚礁生物定位和导航中的作用。他还讲述了珊瑚礁白化事件导致的生态系统破坏以及利用声音恢复珊瑚礁的尝试。Dino Martins 介绍了骆驼蜘蛛独特的交配行为，雄性骆驼蜘蛛为了避免被雌性吃掉，必须小心谨慎地接近雌性。Gary Moore 分享了他对英国黎明合唱的看法，认为这是世界上最伟大的野生动物事件之一，并描述了黎明合唱中鸟类之间激烈的竞争。 Rutendo Shackleton 详细阐述了大象利用低频隆隆声（infrasonic rumblings）进行远距离通讯，保持群体联系的机制，并解释了这种通讯方式对于生活在广阔而危险环境中的大象的重要性。Pauline Fleischmann 详细解释了他们团队是如何通过构建电磁螺旋来干扰地球磁场，从而验证沙漠蚂蚁利用地球磁场进行导航的。Steve Simpson 详细描述了健康珊瑚礁的声景组成，包括各种生物发出的声音，以及这些声音对于珊瑚礁生物多样性的意义。他还解释了他们是如何利用珊瑚幼虫的实验来研究声音对珊瑚幼虫行为的影响。Dino Martins 详细描述了骆驼蜘蛛的交配过程，包括雌性释放的化学和声音信号，以及雄性为了避免被吃掉而采取的谨慎策略。Gary Moore 讲述了他对英国黎明合唱的个人感受，以及他认为黎明合唱是世界上最伟大的野生动物事件之一的原因。

Chapters
The episode starts by discussing the powerful pull of smell, exemplified by the irresistible aroma of freshly baked Colombian bread, and extends this concept to the broader natural world, where various forces influence animal behavior and navigation.
  • The pull of smell is a powerful force in nature, drawing scavengers to carcasses and influencing human behavior.
  • Animals use various methods to communicate and stay together, including low-frequency rumbles for elephants and magnetic fields for desert ants.

Shownotes Transcript

We explore the invisible pulling powers of nature through the forces of smell, sound and gravity.

In Greece, desert ants start their lives underground in total darkness. Void of landmarks and sun they initially learn to orient themselves using the Earth’s magnetic field. German scientist Dr Pauline Fleischman reveals how her team discovered the ant’s internal GPS.

A healthy coral reef is a very noisy place, full of the snapping, rasping, scraping and croaking of various vocal species. But a dying reef is tragically quiet, devoid of the life which can no longer survive on it. However, conservationists have discovered a way to pull species back to these habitats with the ingenious use of underwater

speakers.

This sort of catfishing is used by a number of animals, including arachnids. Sebastian and Rutendo discuss one of nature’s more perilous powers of attraction with Kenyan entomologist, Dr Dino Martins. He describes the dramatic mating behaviour of the camel spider, an alluring species with incredible hunting skills.

Humans might find the British dawn chorus a more soothing courtship ritual. But for the birds, it’s an intense competition. Sound recordist Gary Moore tells us why he

thinks it’s one of the world’s greatest wildlife events.
