Detecting ants is a key part of tracking them, but it's not all that matters. You also need to keep track of who's who -- easier said than done! In this HMC Bee Lab blog post, Livia writes about tracking metrics that take ID into account hmcbee.blogspot.com/2026/04/how-... #ComputerVision @hmc.edu

When a key resource disappears: What wood ant networks can teach us At first glance, the world of ants may seem far removed from our everyday lives. Yet, on closer inspection, they often face surprisingly similar challenges. They live in complex societies where the fu...

What happens when a resource disappears? Wood ant networks reorganize, often recovering well. But if a key resource is lost, the network is reshaped into a less efficient, less robust configuration. It may not recover, even if the resource becomes available again. www.eurekalert.org/news-release...

Protecting habitat is perhaps THE most important conservation strategy. But a proposed change to the Endangered Species Act would stop doing so, allowing people & companies to destroy habitat that endangered species need to survive.
