Lemurs of Madagascar Name: Course: Tutor: Date: Lemurs of Madagascar 1. Madagascar biome is a tropical rain forest. The main characteristic of a tropical rain forest biome is the presence of Warm temperatures throughout the year. In a tropical rain forest biome, there are three layers. These layers include the top trees, followed by the canopy layer characterized by dens leaves hence low light penetration and the third layer are the ground layer. The ground layer lacks any vegetation owing to the low amount of sunlight reaching it due to the dense canopy layer. 2. Changes happening in Madagascar pose challenges to lemurs in the island.
The main changes that affect the lemurs include the effects of agricultural activities on the environment. Forestland conversion for agricultural use including the creation of pastureland, cropland, and degradation of the soil due to fire and clearing by humans is the agricultural changes on Madagascar. Soil erosion caused by slash-and-burn farming also forms the other changes in Madagascar that brings forth challenges to lemurs. As a conclusion, high deforestation rate and increased human population and erosion form the main changes that challenge the existence of lemurs in Madagascar. 3.
The lemurs that are adapting well with the changes in Madagascar are the ones with the ability to live in an altered habitat. (This is a habitat with secondary characteristics owing to human activities in the island). These include the ring-tailed lemur lemma catta and sifakas, but between the two, the ring-tailed lemma catta is adapting better to changes in the ecosystem. The fossil lemurs’ disappearance in the island was due to inability to adapt well to the changes. The other types of lemurs that have disappeared due to change in the habitat include Palaeopropithecus, Daubentonia robusta, Archaeiindris fontoynonti and Megaladapis edwardsi. . A generalist behavioral type is required of the lemurs in Madagascar to be able to cope with the change s in the island for their adaptation and survival. The species favored in this criterion are sifakas and lemur catta, which are adapting well to the changes. Other behavioral characteristics required include being terrestrial for them to adapt well with the changes as depicted by the lemur catta. Physical characteristics that improve adaptation to the changes include ability to take advantage of changes by feeding on crops, tourist handouts, insects, flowers, and fruits. . Lemurs might not develop to adapt to changes in Madagascar because they lived on trees and the deforestation affects their form of livelihood. The reduction in the soil’s ability to support the vegetation that forms the main food for the lemurs is another reason owing to the high rates of soil erosion and degradation. Similarly, human actions in the highland affect their ability to adapt with the changes hence another reason for the inability to adapt to changes in the habitat. 6. The water cycle is the biochemical cycle that may be altered by activities in Madagascar.
An alteration on the water cycle takes the following pattern owing to the activities in mainly deforestation and soil erosion and degradation. Cutting of rain forests results in low moisture transpiration to the atmosphere. The result is a reduction in the cloud cover, diminished precipitation, and lead to drought in the area. The replacement of the forests requires water hence an impossible occurrence when there is drought in the area.
