Nature has an amazing way of creating diversity: more species create opportunities for even more species🌴🐛🦟. But can this continue forever? Our research suggests there are limits. We found parasite diversity constrained by survival in landscapes. Preprint: tinyurl.com/mskh4nf3

New #ecoevo paper @pnas.org: Evolution of species’ range and niche in changing environments. I show that feedback between evolutionary and population dynamics can create a tipping point where genetic variance erodes, and species’ ranges contract or fragment www.pnas.org/doi/10.1073/... #popgen 🧬🧪 🌎

Preprint finally out! I show that eco-evo feedback can drive a tipping point where genetic drift overwhelms adaptation. This can result in a contraction of a species' range border or range fragmentation. Fragmentation is abrupt and arises readily under rapid temporal change. doi.org/10.1101/2025...
