Fig. 3 Fitness distributions of niche value for three types of species. Species types are based on niche breadth: specialist species with specialist organisms (SPE), generalist species with specialist organisms (GEN-spe), and generalist species with generalist organisms (GEN-gen). Thick lines represent species distributions, whereas dotted lines represent distributions for organisms. Note that specialist species will have higher fitness than generalist species for the niche value where they are adapted for
