It’s a story of how animals perceive risk and the limitations of our human perceptions. Read the preprint to find out more! 5/5 doi.org/10.1101/2025...
Not so scary after all? Decoding the landscape of fear through hormonal responses to risky times and places
Prey must balance the energetic benefits of foraging with avoiding predation risk. This risk-reward trade-off, a cornerstone of behavioural ecology, hinges not only on realized predation risk but also...

So what’s going on? Looking closer at their GPS tracks hints at a clever strategy: forage in cropland, then duck into the forest to rest and de-stress. 4/5

Elk usually forage in cropland, which should feel risky.
But big surprise: their hormone levels don’t indicate they feel fear there. 3/5

We put that idea to the test by tracking wild elk and measuring two hormones that mean fear (glucocorticoids, or GCs) and refuelling (T3). 2/5
