The paper explores seed dispersal mechanisms in three different plant communities, and looks at the role of birds and animals in the maintenance of plant biodiversity and ecosystem survival. The paper also shows how hurricanes, and manmade disasters, such as severe deforestation, effect plant diversity and density. The paper successfully demonstrates the importance of natural forces, such as plants and animals, in the maintenance of plant species biodiversity within an ecosystem.
From the Paper:"Ecosystems are dependent on many different factors for survival. These ecosystems are maintained by interactions between climatic conditions, vegetative growth, and the number of animals within the community to consume the plants. Seed dispersal is one of the most important of ecosystem processes.
"Many seed dispersal mechanisms depend on animals. They depend on the animal's diet, habitat, numbers, and pattern of movement through the forest (Wescott, 2007). The length of time that the animal retains the seeds and the pattern of their movements determines plant dispersal in the rain forest. Seed dispersal also depends on whether the landscape is continuous or fragmented. These factors have a dramatic impact on the structure of plant and animal communities. The efficiency of seed dispersal affects the dynamics of the plant and animal communities that live within the area."
