Abstract excerpt
Elevational gradients are frequently linked to dramatic biodiversity shifts, but the drivers and dynamics of alpine adaptation often remain unclear. A Batesian mimicry polymorphism in Aotearoa New Zealand stoneflies provides an ideal system for assessing the role of elevational gradients in selecting for melanic (dark) versus non-melanic (light) colour phenotypes. Although previous studies have proposed that...
