Predators and Eco establishment ManagementNatural Resources ManagementPredators have an everlasting offspring on different kinds of ecosystems.They influence there ecosystems by controlling the teemingness of lower speciescertain habitats. In this article, Predators and Ecosystem Management by(James A. Estes). He explains results of fact studies that indicate importantecological graphemes for predators in a huge coastal ecosystem. The main challengein this article is to determine if there argon recurrent patterns else where innature and to also understand when and where they continue.The author gives his spot on predators and the coastal ecosystemsby giving us a donjon example, the sea otter and the kelp forests. The relationbetween the sea otters and the kelp-forests was provided because of a accidentof history, the over-exploitation of sea otters in the Pacific maritime furtrade. The study comp bed areas where sea otters were easy with nearbyareas to areas where theyre alm ost extinct. By doing this comparison of thesea otters coastal system it was possible to gain much insight into the seaotter ecological role in kelp-forest ecosystem. Over the years its beenpossible for us to observe the kelp-forest ecosystem over-time, thank to themassive growth of the sea otters population we observed the change from otter- forgo to otter-dominated.This article relates to many aspects of our textbook. On page 89 inchapter 5 the text explains what an ecosystem is, defined by the book, its acommunity of species interacting with one another(prenominal) where there is a non-livingenvironment. In this case the otter and kelp-forests ecosystems a coastalecosystem. As mentioned in the book, the food chain is involved in the sequenceof events with the being that are the source of the food. In a survey ofcoastal habitats in many areas of the North Pacific Ocean have revealed thatkelp forests usually are extensively deforested where sea otters are absentwhereas this condit ion is rare where occur ( Estes and Duggins 1995).All ecosystem management has recently emerged as the main way of
