Hottola (2009) has studied the ecology of polypore fungi and their responses to forest management. Habitat loss and fragmentation affect not only species diversity but also the relative abundances of the species and, consequently, species interactions. Changes in species distributions and abundances are likely to affect the food chains in which wood-inhabiting fungi are involved, and thus the functioning of the whole forest ecosystem. This highlights the importance of protecting well-connected, large and high-quality forest areas instead of small fragments distributed across the landscape. Download the thesis here.
