PLANET EARTH Seasonal Forests
Nectar was an excellent first course for the lemurs but moths are the main dish. The moths are very important to the lemurs for they will replenish（补充） the fat reserves that the lemurs need to survive the barren dry season. The lemurs might seem to be a pest for the baobab. They kill it's pollinators（传播花粉者） and rob it of its nectar but they do give something in return. For, as the wrestle with the moths, their fur inevitably becomes dusted with pollen, so they, too, become pollinators.
As the alternation of wet and dry seasons brings change to some tropical seasonal forests so the progression of summer to winter dictates life in more temperate regions. Whether trees have needles or broad leaves it is their ability to survive annual change, that has enabled them to cover such vast areas of the Earth and made the seasonal forests the greatest seasonal forests of all.
