| What are the four tenets of conservation biology being value laden and mission driven? | -diversity of organisms is good -ecological complexity is good -facilitate evolution: vital for population -biotic diversity has intrinsic value |
| What are the four tenets of conservation biology being value laden and mission driven? | -diversity of organisms is good -ecological complexity is good -facilitate evolution: vital for population -biotic diversity has intrinsic value |
| What was the significance of the US congress approving the bill for Yellowstone National Park? | -natural heritage made accessible to everyone -uniquely democratic -the "greatest idea in American history"-emulated worldwide |
| What is the definition of conservation biology? | A crisis discipline whose goal is to provide principles and tools for preserving biodiversity |
| What are the four ethical roots and foundations of conservation? | -all living creatures possess intrinsic value -land ethics -physical environments and living organisms perform vital services that support ecosystems and human civilization -the physical environment and its creatures ass value and virtue to the experience of being human |
| Why were early domestic livestock farms not needed? | There was an abundance of wildlife to use for food |
| What is the name of the expedition that explored the Louisiana purchase? | Washburn expedition |
| Why was the idea of yellowstone being preserved significant in the aspect of the economy at the time? | There was a lot of revenue that could have been generated from things such as waterfalls(hydroelectric), bison(agriculture), and trees(timber) |
| Who was john Muir? | Man of faith that created the sierra club. he asked the essential question in American conservation, "what is the best use of nature and natural resources?" |
| What are the key aspects(4) of a nongovernmental conservation organization? | -focused mission -political involvement -public disclosure -legislative disclosure |
| When does authentic conservation occur? | When, resource use is < maximum sustainable rates; we forgo using some resources |
| What are the origins of conservation policy? | -Muir created the model for nongovernmental conservation organizations (NGO's) -1873: congress approves "timber culture act" -1891: "forest preservation act" -development of resource conservation ethic -merger of academia and conservation -national wilderness preservation act -public environmental awareness emerges |
| Why was the need for the timber culture act? | Was needed because of the misuse of timber companies by not replanting the land that they took from the federal/state government |
| Why was the forest preservation act needed? | It broke up industrial monopolies trying to claim natural resources as theirs; the act made it so that natural resources belonged to citizens |
| What is the main aspect of transcendental theory? | Its the ideal that all things have intrinsic value and that is their main use |
| What is the conservation resource ethic? | The idea of sustainable use of resources while achieving maximum yield; ultimately that resources can be used respectful if done properly |
| What makes conservation biology different from other environmental and biology classes? | -focuses on the study and preservation of the diversity of life -it is value laden and mission driven -advocacy oriented -crisis oriented -integrative and multidisciplinary -concerned with evolutionary time -an adaptive science -a legally empowered science |
| What are the four tenets of conservation biology being value laden and mission driven? | -diversity of organisms is good -ecological complexity is good -facilitate evolution: vital for population -biotic diversity has intrinsic value |
| What has been the shift in conservation goals? | Instead of solving species loss its now solving biodiversity loss and safeguarding ecosystem services |
| What is biodiversity? | The structural and functional variety of life forms at: genetic, population, community, ecosystem levels |
| What is the problem with the phylogenetic species idea? | -it would cause 50% more species to exist phylogenetically -the populations of species would be smaller -10% of these species would move from vulnerable to endangered |
| What are the 3 ways diversity is measured? | -alpha -beta -gamma |
| What are the 2 main components of alpha diversity? | Species richness and evenness |
| What is species richness? | The presence or absence of species |
| What are the advantages of using species richness? | Easy to collect; measure presence/absence; easy to present and compare with similar sites |
| What is evenness? | The similarity of abundance |
| What does low evenness of a species mean? | That another species is more abundant |
| What does evenness require to calculate? | The number of individuals of each species |
| What techniques can be used to quantify alpha diversity? | The shannon weiner technique and the simpson technique |
| What is beta diversity? | Measures the rate of change in species composition of communities across a landscape |
| What equation does beta diversity use? | Wittaker's measure |
| What does beta diversity evaluate? | If species are lost/gained due to site age, disturbance, or gives insight into successional chanage |
| What is gamma diversity? | The diversity of species across larger landscape levels; the rate at which additional species are encountered as you encounter the same habitat at greater geographic distances |
