Article Synopsis
- Plant populations in farms are affected not just by how their areas are cut off, but also by what is around them in the landscape.
- We looked at a forest plant and bumblebees in three different farming areas to see how these bees move and help link the plant populations together.
- The movement of bumblebees was influenced by fields of corn and grassy areas, showing that how bees travel impacts the plant's gene mixing and overall health.
Due to multiple land-cover changes, forest herb populations residing in forest patches embedded in agricultural landscapes display different ages and, thus, experience differences in genetic exchange, mutation accumulation and genetic drift. The extent of divergence in present-day population genetic structure among these populations of different ages remains unclear, considering their diverse breeding systems and associated pollinators. Answering this question is essential to understand these species' persistence, maintenance of evolutionary potential and adaptability to changing environments.

However, little is known about how the interactions of seed and pollen dispersers with the agricultural matrix translate into gene flow among plant populations.
Objectives: We aimed to identify effects of the landscape structure on the genetic diversity within, and the genetic differentiation among, spatially isolated populations of three temperate forest herbs.
