Conservation 1. Contrast wilderness areas with wildlife refuges. Do you think each of these areas continue to fulfill their original purpose for which they were created?  2. How do the principles of island biogeography (the “island” drawings & examples in the lecture video) highlight these two important issues for conservation, especially for areas in the middle of developed landscapes? a. Size of area preserved - b. Distance from “mainland” - 3. What is the “edge” and “core” area of a reserve? Why is it so important to maximize “core” habitats?

Match the problems for biodiversity with the solutions.     Train more scientists.   Establish payments for land managed to enhance conservation.   Train and hire local people to work in protected areas.   Understand the diverse values of different societies and organizations.   Financial subsidies to industries that damage the environment should end.   1. Ecosystems lack monitoring. 2. Economic decision making often fails to include ecosystem services. 3. Revenues associated with protected areas do not directly benefit local people. 4. Endangered species occur on private land. 5. Many businesses remain uninterested in conservation issues.

A  B C D1 Forest floor refers to the growth that is found directly on the ground in the forest. This includes grasses and mosses and other low lying plants.2 Soil holds the nutrients and moisture required for all plant growth.3 Sub-canopy refers to the layer of plant organisms that are directly under the canopy. It includes smaller trees and larger shrubs. 4 Canopy describes the highest layer of a forest ecosystem. It includes the large trees that provide shade and shelter. Which one is which one

Habitat fragmentation results from human activities that change large blocks of landscape, leading to many negative effects on species and ecosystems. Which of the following is not one of the possible consequences of fragmentation? A. reduction of available habitat O B. increasing degradation of habitat patches C. increasing wind speeds and temperatures at patch edges D. spatial isolation of patches E. increase in top predators present in patches

1) Compare the biodiversity indices to one another. State a claim about the effect of pollution on the biodiversity of the stream ecosystem. Describe how the pollution levels affect the species richness and biodiversity of the stream. Justify your claim with evidence. Describe the difference in species richness you observed. Explain how human intervention can change biodiversity in positive ways.

If you wanted to protect diverse species in coastal marsh, you should identify the right habitat by fınding -- a bed of grass underwater but near the shore an area of land that is periodically covered by saltwater a deep, fast-moving river a flat, grassy area that is elevated above sea level so that it stays dry except during floods an area with dense mangroves

Some people think that the species living on earth today will eventually become extinct and be replaced by others and that it is therefore not important to protect biodiversity. How so?. Others think conservation is a critically important undertaking for humans today. How so?
