Study Guide for Test 2 Wildlife and Fisheries 175 Fall 2009 Exam II will cover 5 Chapters 4 7 9 10 11 All exam questions come from class discussion Please read the book prior to lectures It is an excellent resource Use the book to help you study but do not try to memorize everything in it there are good practice questions at the end of each chapter Use this study guide to help organize the material and study But please do not just study this study guide because there might be something missing though not intentional The test will be worth 100 points It will consist of multiple choice questions fillintheblanks and short answers Study hard but more importantly study smart and good luck Also don t forget to see me if you need help georgemerovichmailwvuedu CHAPTER 4 Genetics and Evolution in Wildlife and Fisheries Be familiar with basic genetics You have probably already had this in your biology classes and it is important to ecologist too What are genes What are their functions Know and be able to use these terms diploid polyploidy allele homozygous heterozygous dominant allele recessive allele genotype phenotype Understand how genetic diversity exists on multiple levels individuals populations species What is a species How do species arise ie explain how speciation might occur What are isolating mechanisms and why are they important What is allopatric speciation Name some mechanisms of evolution Explain how natural selection works Compare contrast and give examples of directional stabilizing and disruptive selection not covered this semester Be familiar with some myths of evolution and natural selection What is a subspecies Why is it important to protect geographically separated populations of subspecies think of genetic variation environmental heterogeneity and adaptation Evolution by natural selection requires that there be genetic variation effecting fitness What are some sources of genetic variation Compare and contrast founder effect and bottleneck effect How is inbreeding deleterious to genetic variation within the individual and within a population If inbreeding is bad then outbreeding must be good right But this is not always the case How can outbreeding be bad to the genetic variation of the individual or a population What is biotechnology Give some examples in wildlife and fisheries fields What is a transgenic individual What is a hybrid What is heterosis Give examples of hybrids in fisheries What are the characteristics of specific examples of hybrid fish ie why do fisheries managers crossbreed

use sampling devices CHAPTER 9 Population and Community Assessment Wh would wildlife and fisheries ecologist want to assess population and community characteristics Define in common language the following statistical terms mean range standard deviation confidence interval What is the difference between a sample and a census What is relative abundance vs absolute abundance What is an index

invertebrate biomass Fish IBI WVSCI EPT How are community assessment indexes used in research or law Why are wildlife and fish individuals marked or tagged What is the difference between marks and tagsbands What are some different types of marks and tagsbands Which are examples of mutilation techniques Understand why markstagsbands should not affect animal behavior survival probability of capture in field studies What is biotelemetry CHAPTER 10 Managing the Biota 0 Give examples of how individual populations are managed Give examples of how communities might be managed How are partial or complete removals achieved Why would this be desired by fisheries or wildlife biologists What is biomanipulation What does it mean for a community to be regulated from the top down from the bottom up In aquatic systems what has been the purpose of biomanipulation How are contraceptives polyploidy and repellants used to control populations Why do we hunt and fish What is the difference between introductory maintenance and supplemental stocking What are putandtake vs putgrowandtake fisheries What are the advantages and disadvantages of each How can stocking of fish and wildlife be harmful How can it be good What is a twostory fishery CHAPTER 11 Endangered and Threatened Species 0 What is the difference between background and mass extinction rates How many mass extinctions have occurred over evolutionary time What are some things that are believed to have caused mass extinctions in the past What is the sixth mass extinction Explain some of the important reasons why species are becoming extinct endangered and threatened today Give examples of species that have gone extinct or have become endangered because they were hunted illegally and were considered pests Why were prairie dogs considered pests What happened to the blackfooted ferret as a result What was the fate of the passenger pigeon Why do introduced species threatened native species How is the pet trade harmful to the existence of exotic species What is generally accepted as the most important reason why species become extinct endangered and threatened today What is biomagnification List reasons and give example of why species are important to protect and save What is the difference between anthropocentric and biocentric approaches to saving species Where do all of our resources that we need to live come from What is ecotourism Give some examples of ET species and give examples of species that have recovered Is it worth saving species What is a novel and broader approach to saving species What are BMPs What is biodiversity hint it is not just a list of the different species What are the problems with taking an ecosystems approach to saving biodiversity Study Guide for Test 3 Final Wildlife and Fisheries 175 Fall 2009 810AM Friday December 18 The Final Exam will cover 6 Chapters 1217 We will probably not get to all of chapters 1819 as stated on the syllabus The nal is not really comprehensive but I will assume you are familiar with all previous material covered ie terms concepts as I develop the questions for the new material There will be no specific questions regarding information from the first two tests However you should know that material to help you understand and answer questions regarding the current course topics Your mastery of that material will ensure your success on the final All exam questions come from class including lab discussion but don t forget the terms and concepts to know on your know that we didn t cover in class but were on the lecture handouts Please read and review the book chapters we covered in class as an aid for studying It is an excellent resource Use the book to help you study but do not try to memorize everything in it there are good practice questions at the end of each chapter Use this study guide to help organize the material and study But please do not just study this study guide because there might be something missing though not intentional The test will be worth 150 points It will consist of multiple choice questions fillin theblanks and short answers Study hard but more importantly study smart and good luck Also don t forget to see me if you need help georgemerovich mailwvuedu CHAPTER 1213 Habitat Tylgesa Sampling and Assessment 0 What is habitat What are biomes What are ecoregions Know the general
