Red campion wildflowers maintain healthy genetic connections across human-altered landscapes, with pollen traveling both short distances and surprisingly far from outside local populations — suggesting this common plant is more resilient to habitat fragmentation than expected.
1
Sampling 1,005 individuals across 29 populations found no reduction in genetic diversity linked to population size or degree of human land-use change
2
Paternity analysis of 4,800 offspring showed pollen dispersal is mostly short-range (under 10 m neighborhoods) but with substantial long-distance immigration from outside local populations
3
Genetic differentiation among populations followed an isolation-by-distance pattern with high admixture, and landscape composition did not explain differences — suggesting gene flow is resilient to anthropogenic habitat alteration
