To achieve a comprehensive understanding of magnetoreception and vertebrate navigation, it is essential to understand whether the mechanisms and principles of magnetoreception are similar across taxa. In this project, we will focus on migratory bats. By measuring orientation decisions following magnetic treatments in either a field laboratory or under free-flight conditions in radio-tagged bats by utilising a network of digital telemetry stations, we are now able to test the two prevailing hypotheses, the radical-pair-based and the magnetic-particle-based magnetoreception mechanism, in a mammalian model.

为了全面了解磁接收和脊椎动物导航，必须了解磁接收的机制和原理是否在不同的类群中是相似的。在这个项目中，我们将重点关注迁徙蝙蝠。通过利用数字遥测站网络在野外实验室或在无线电标记蝙蝠的自由飞行条件下测量磁处理后的取向决定，我们现在能够在哺乳动物模型中测试两种流行的假设，即基于自由基对和基于磁粉的磁接收机制。
