BIO 227 Lecture 2  The Difference Between “Wildlife” and “Biodiversity”  “Wildlife” doesn’t have a precise definition, usually leaves out invertebrates, not  domesticated, gaming/hunting animals  “Biodiversity” is a much broader term  For this course, “wildlife” = “free­ranging vertebrates, especially terrestrial birds and  mammals”  “Biodiversity” means the variation of life at all scales, the variety and variability of life  3 Scales of Biodiversity: ecosystem, species, genetic  Ecosystem: a biological community of interacting organisms and their physical  environment  Species: number of different types of organisms in an area  Genetic diversity: genetic variability within a species (ex. Height, color, health),  decreases inbreeding such as Facial Tumor Disease in Tasmanian Devils  What Good is Biodiversity? A. Instrumental Values (benefits to humans) Consumptive benefits­ food, medicine, other products Non­consumptive benefits ­ Recreation, spiritual, and service benefits (pollination, pest control, erosion  control) B. Intrinsic Value (irrespective to humans) Ecosystem services: the benefits for humans that arise from healthily functioning  ecosystems Expenditures for consumptive use of wildlife  A fundamental tenet of conservation biology is that species and ecosystems have intrinsic value  How do you quantify the intrinsic value of biodiversity or wildlife? ­ “Willingness to pay” How much would you be willing to pay to save Giant Pandas? ­ Compensation Approach If Giant Pandas went extinct, how much should you be compensated?  What is Management?  Implies human manipulation and requires planning: goal, process, fund assumptions  The role of Science?  To inform the process of management for desired incomes  But management is socio­political and is dependent on social values
