Madagascar has dry forest, rain forest savanna and grassland biomes. Some major features of the Tropical Rain Forest biome are warm, wet and high levels of biodiversity. A tropical rain forest is divided into four different layers. Those layers are the forest floor, the understory layer, the canopy layer and the emergent layer. The biggest change happening in Madagascar that is posing challenges to lemurs in Madagascar is the deforestation of the rain forest. This completely disrupts the lemurs eco system, its home and its food supply. An example of a lemur that is not adapting easily to the changes in Madagascar is the bamboo lemur. If you cut down bamboo, you take away it’s food supply and they cease to exist. The ring tailed lemur seems to be the most abundant lemur because it has the ability to adapt the best. It seems that all lemurs are threatened but the ones that are doing the best are the lemurs that do well in secondary habitats, meaning habitats altered by humans. We do have a way of coming into an area and completely disrupting everything. I think the lemurs will have problems adapting to the changes being thrown at them because they are constantly subject to changes...
