In this lesson, our instructor Bryan Cardella gives an introduction on wildlife and endangered species. He discusses sustainable yields and viable populations, carrying capacity, managing wildlife, ages structure and harvests, fisheries, endangered species, extinction, and overabundance.
When it comes to wildlife and endangered species, we must consider: maximum sustainable yield, the minimum viable population, and the optimum sustainable population
Carrying capacity and logistic growth curves relate the maximum sustainable population in an area to the resources of that given habitat
In managing wildlife the IUCN has a 4 principle approach: safety factor in terms of population size, concern with the community/resources, maintenance of the ecosystem/minimizing adversity, and continual monitoring and assessment
Age structure and harvests impact our knowledge about species in the wild. The catch per unit figures are also informative in determining total population numbers
Fisheries are dominant in a few countries: Japan, China, Russia, Chile, and the United States. Fish harvest data recently has been alarming, leading to the question: Are fisheries sustainable in the long run?
Endangered species and threatened species have value to the human population in many ways. Their existence in the future truly depends on how we treat them and their resources
Extinction can be local or global, and thankfully some endangered species have been helped back into larger population numbers
On the other hand, some species are overly abundant and can encroach on the human population
