Using the bamboo lemur as an example, if people continue to cut down the bamboo, the lemurs will not have food and they could become extinct very quickly. 3. Which types of lemurs are adapting to the changes? Which types of lemurs are not adapting well? Why?
I am going to discuss some of the major features of the Tropical Rain Forest biome. They are wet, warm, and also high levels of biodiversity. The tropical rain forest is divided into four different layers, and these layers are forest floor, the understory layer, the canopy layer, and the emergent layer. 2. What changes happening in Madagascar are posing challenges for lemurs?
In the tropical rain forests, temperatures throughout the day are warm and rain occurs almost daily. The soil is highly-weathered, according to Berg, Hager, & Hassenzahl, (2011), and ancient and poor in minerals. The trees in this biome form a canopy which allow little sunlight to reach the forest floor. 2. What changes happening in Madagascar are posing challenges for lemurs?
Tropical rainforests are rapidly disappearing in a way that will greatly have an impact on planet earth. Since 1950, half of all tropical rainforests are gone because deforestation, mining and many other things are taking nature away from us. In a few decades, it has been estimated that the rest will be gone if we measures are not taken soon. The WWF (World Life Federation) oversees this ecological threat. They are working to save nature by helping people live in harmony with nature.
Small changes in an ecosystem can highly damage the abundance of specific species such as insects and marine life (fish species are adapted to very regulated temperatures, any change in water temp can often be detrimental to fish species). The Daintree Rainforest community supports an extremely vast range of organisms, a single hectare of the wet tropics can contain around 42,000 difference species of insects, up to around 15000
Pre Lab Questions: 1. Explain the reasoning behind the classification of biological hotspots. * A biological hotspot is an area that is rich in biodiversity but is being threatened of extinction 2. What reasons are there for classifying Madagascar and the Indian Ocean Islands as biological hotspots? * Madagascar and the Indian Ocean were once a place of high plant and animal diversity and population however, in the last 1500 years people have come into this untouched environment impacting these species due to their lack of knowledge on human involvement.
Its location spans from Brazil into Northern South America. The Amazon is home to approximately 5 million different species of animals, plants, and insects. The Amazon Jungle, as it is commonly known in English, is a magnificent broad-leafed rainforest. In the Amazon you can find a large amount of food and resources such as fruits, nuts, oil, lumber, and many types of animals. These things are not only useful to us but also to residents and tribes of the rainforest and to the many species that live there.
However due to illegal logging and the government’s agricultural policy, it had resulted in the loss of many forests. Without these forests there will be no vegetation to intercept the rainwater. Besides that since Thailand is geographically sloped at angle without trees to secure the soil together, it will increase the chances of soil erosion so the soil and mud will be washed into rivers causing them to be shallower. Furthermore the bare slopes that remained will result in increased surface runoff. Similarly in Boscastle, farming in upper course had led to deforestation and removal of hedgerows decreasing the amount of interception from higher ground.
The main factor behind this tragedy is that they are native only to the tropical rainforests in the islands of Borneo (shared between the countries of Indonesia and Malaysia) and Sumatra (in Indonesia), these rainforests are rapidly disappearing due to logging and the expansion of huge palm-oil plantations that are replacing the rainforests at a very fast pace. This means the orang-utans are losing their home and their food source. The Sumatran orang-utans are critically endangered as there are only as few as 6,000 left in the wild. Over the past 100 years the population has decreased by 91% and continues to become fragmented and isolated and many of the populations are no longer viable. The Bornean orang-utan species has about 40,000 animals left in the wild, a much healthier number then the Sumatran orang-utan but still not ideal.
