Waxy needles prevent evaporation in evergreen trees. Waxy coating appears in new leaves and will thin out as they age. Most importantly in the first year of a pine needles life, the wax prevents some water loss to make up for the dry environment. The stomata open up to exchange gases and water vapour is lost along with the gases. A wax concentration can help to prevent this water loss.
Evergreen plants have the ability to photosynthesise quickly as temperatures start to rise. Plants will respond positively to rising temperatures for the to photosynthesise and the photosynthesis relies heavily on temperature and soil temperature. Evergreens don't lose their needles in Winter and this means that the plants can photosynthesise from the moment the weather begins to warm and the dark colour of the needles support them in absorbing heat for the process to begin.
In order to provide a longer and healthier life, moose can lower their body temperature. Moose can often struggle to find enough food to live on in the Winter, so lowering their body temperature will decrease their need for food. This adaptation has originated from Moose lacking food sources in the Winter and needing more food sources. Lowering their body temperatures can prevent them from dying in the Winter.
During the Winter, food can also become insufficient for animals. So animals living in the Taiga need to have adaptions to allow them to digest different types of food material. Animals that may normally feed on grass, are adapted to digest tough needles and even sometimes bark when grass is unavailable to them.
