Description
Praveen Dhyani, Franziska Deppe, and Klaus Fischer present a 2026 study of the small white butterfly across western Germany. Broken-up landscapes are expected to cut populations off from each other, letting their genes drift apart. A strong flier that eats many plants, though, might shrug off that pressure, and this species is both.
The team read genome-wide markers from butterflies in four landscape pairs, each matching a stark modern farm landscape with a varied traditional one. Genetic differences came out near zero, with no pattern of distance between sites. The authors read the population as one freely mixing whole, buffered by flight power and flexible habits.
