The profile of the Earth and all its biomes have changed drastically over millions of years due to the continental drift that broke up Pangaea. The changes in the distribution of landmasses has caused drastic changes …show more content…
Buttresses are often found in locations with poor soil quality. In biomes like the temperate deciduous forest biomes the trees have no need for buttresses because the soil is rich with nutrients. Rich soils allows for trees and plants to grow deep roots that anchor and provide them with stability. In addition deep root systems take up nutrients that are found throughout soil. Buttresses do not penetrate into the deep layers of the soil this could affect stability in places like the desert. Also shallow roots would prevent the uptake of much needed water and other nutrients that are hard to find in the desert biomes. The finding adaptation of drip tip leaves outside of the rainforest biome is unlikely. The point of drip tip leaves is to remove moisture and rainfall from leaves of plants, keeping them dry. This would be particularly unbeneficial to desert biomes due to the lack of rainfall. If plants in this biome contained drip tip leaves, the plant could would not be collecting the much need water, rather, removing it from its surfaces. If rainfall did occur it would most likely run right off the waxy leaves and be soaked up by the soil instead. This would ultimately starve the plant of water killing …show more content…
They occur due to things like lightning strikes or other factors. They are a natural succession of a forest. When a forest becomes too dense they block smaller vegetation from sunlight. When a fire occurs it allows more space for new vegetation. Vegetation within this biome have evolved and developed specific traits in response to wildfires. Some trees require fire by requiring it to help germinate or reproduce. While others are more fire tolerant being able to withstand a degree of burning and continue to grow even after being damaged by fire. This can be due to bark thickness or being able to grow new shoots after being damaged by a fire (Bond et. al, 2001). Two examples vegetation having these adaptations is the pitch pine, Pinus Rigida and quaking aspen (Populus tremuloides). Pitch pine cones can open when exposed to fire. Locations that have a long history of wildfires the seeds only open when exposed to heat. Another way that the tree adapts to fire is that they have very thick bark and contain high amounts of resin, this helps withstand high temperatures. Pitch pines also contain dormant buds able to grow after being exposed to fire. Only the buds at the base retain the potential for growth. This often common in hardwoods but not in conifers. They are mostly located up the east coast of North America (Northern Woodlands, 2010). The quaking aspen are able to grow new shoots after being exposed to
