Chapter 55 Conservation Biology and Restoration Ecology Lecture Outline Overview: The Biodiversity Crisis Conservation biology integrates ecology, evolutionary biology, physiology, molecular biology, genetics, and behavioral ecology to conserve biological diversity at all levels. Restoration ecology applies ecological principles in an effort to return degraded ecosystems to conditions as similar as possible to their natural, predegraded state. Scientists have described and formally named about 1.8 million species of organisms. Some biologists think that about 10 million more species currently exist. Others estimate the number to be as high as 200 million.

POPULATION GENETICS: HOW TO SOLVE HARDY WEINBERG PROBLEMS. Hardy and Weinberg stated that Nature really wants things to be balanced (meaning not changing). However, we know that Nature is constantly changing. So, when one thing in nature changes, it usually leads to a lot of other things having to change. Hardy and Weinberg came up with a hypothesis/idea that explained how populations could grow or change. It had 5 parts to it. In order for a population to be at equilibrium (not changing), it must 1. Have no mutations occur 2. Have nothing moving in (immigration) or moving out (emigration) 3. Have no natural selection 4. Have a large breeding population 5. Random mating Now, you know that nature changes. Lets look at how/why.

John Lee Mrs. Tanner AP Bio p.4 December 16, 2010 Prelab 12 A 1. What is the biological importance of carbon and oxygen cycling in ecosystems? Carbon and oxygen cycling is important to ecosystems. Living organisms like animals take oxygen from the atmosphere (or from water) and use it for?respiration. During respiration, oxygen is converted into carbon dioxide and water. Carbon is important to the ecosystem because carbon forms the framework for the organic molecules essential to all organisms.
