On parts of Isle Royale, large, dense moose populations can eat so much balsam fir that the population of these favorite food plants drops. When this happens, moose may suffer from l ...

FISH 312: Fisheries Ecology

However, even some of these factors (freezing, flooding, high temperatures) may interact with density. For example, at high densities, some organis ...
