Many animals use the Sun compass to guide their movement, sometimes over thousands of kilometers. Consistent use of the Sun compass relies on the endogenous clock to track the Sun’s arc, yet animals traveling east-west experience time shifts, potentially causing mismatches betwee...

Why don't all birds lay early? Causes and consequences of breeding timing for a long‐lived migratory seabird

The relationship between earlier laying and higher breeding success is well-established in avian species. However, a wide distribution of breeding timings is often maintained within a population, and the causes and consequences of this variation require further exploration, parti...

Rethinking Environmental Impact Assessment for nature positive development

Achieving nature positive development within existing regulatory frameworks will be challenging. Halting and reversing biodiversity loss requires restoration and enhancement of ecosystems alongside a fundamental shift in how we value biodiversity and assess quantifiable improveme...
