Summary

Story summary

A 15-year study in Michigan shows habitat fragmentation is causing inbreeding in Eastern Massasauga rattlesnakes, reducing fitness and survival.
Inbred snakes are 13% less likely to produce surviving offspring and have an 11.6% lower annual survival rate.
Proposed conservation efforts include wildlife underpasses and relocating snakes to improve genetic diversity.
The study emphasizes the ecological role of these snakes in wetland ecosystems.
