"The findings also highlight changes in the 20th century, when conservation policies altered the animals’ behaviours – with hunting bans, restricted winter migration, and a decline in natural predators, herbivore populations grew.
Based on plant pollen, microalgae and plankton present in sediment samples, the team think that these expanding populations consumed more local vegetation, such a willow and Idaho fescue, which in turn spurred on diatom (algae) growth in the lake."
