Landscape features impact connectivity between soil populations: a comparative study of gene flow in earthworms.

abstract：:During the co-evolutionary arms race between plants and herbivores, insects evolved systematic adaptive plasticity to minimize the chemical defence effects of their host plants. Previous studies mainly focused on the expressional plasticity of enzymes in detoxification and digestion. However, the expressional response...
