Machine learning and AI tools will change how we do ecological research. But, there are major barriers to getting high-performing models.

In our latest paper, we argue a need to re-think model performance by integrating it into a hypothesis testing pipeline:

Rare seasonal brain shrinkage in shrews is driven by water loss, not cell death Common shrews are one of only a handful of mammals known to flexibly shrink and regrow their brains. This rare seasonal cycle, known as Dehnel’s phenomenon, has puzzled scientists for decades. A study...

Scientists discover the secret behind the shrew’s amazing ability to shrink their brains 🧠

The clever trick sheds unwanted weight without compromising too much on cognition.
