Mp: several distinct populaions along with areas of suitable, but unoccupied habitats. Populations eventually go extinct, and are then repopulated. High quality habitats produce extra amounts of individuals that can be supported in the lower quality habitats. Insect feeds on decaying tree some decaying trees are not discovered = some good habitats are not discovered. Finland plantations of aspen wood for paper production. Ne russia this portion of russia is underdeveloped so it looks more natural (young, old and broken" trees) Presence of rare insects rarity classes of insects with reference to finland. V = vulnerable, r = rare, e = endangered, ex = extirpated. In habitat where there are very few logs (finland) it is harder for insect to find suitable habitat, but they can find natural habitat in russia more rare species of insects found in ne russia than in finland. Mosaic of different age (and therefore light) classes.
