Review for Exam 3 Know the elements of theories about the nature of species and where they came from before Evolution was suggested Essentialism Special Creation Catastrophism Progressionism Know what was already known about Evolution before Darwin proposed his theory from comparative anatomy and geology Know what ideas and experiences contributed to the development of DanNin s theory of ENS Know the 2 major themes of DanNin s theory and the essential elements of required for evolution by natural selection Know how ENS con icts with previously held ideas about the nature of species and where they came from Know how DanNin used each ofthe following as evidence for ENS arti cial selection the fossil record comparative anatomy comparative embryology biogeography Know what the Paradox of variation is and how the rediscovery of Mendel s work contributed to resolving it Be able to de ne gene pool allele frequency genotype frequency phenotype frequency gene xation and genetic variation and know how they are related to each other Know what the HardyWeinberg theorem says and what condition are required for a population to remain in HW equilibrium Know the populations genetics definition of evolution and how the HW theorem is useful in the study of evolution Know how each of the following affects gene and genotype frequencies in populations genetic drift mutation gene ow nonrandom mating and natural selection Know the story of the peppered moth and the lesson it taught Be able to de ne and know the relationships among natural selection adaptation and relative tness Be able to de ne and distinguish directional stabilizing and diversifying selection and know how each is expected to affect the mean and variance ofthe phenotype distribution in a population Know what evidence we have that there is genetic variation in natural populations and know the 2 historical views of how much genetic variation there is and what determines this Know how electrophoresis permits detection of genetic variation in natural populations and what the application ofthis technique has taught us Be able to recognize and distinguish 4 genetic mechanisms and 2 general patterns of natural selection that promote the maintenance of genetic variation in natural populations Know what a cline is what mechanisms can cause clines and how reciprocal transplant experiments can be used to determine what causes a cline Know the basis for the Morphological and Biological species concepts and the advantages and disadvantages of each for classifying organisms Know what makes the Biological Species concept superior for the study of evolution Be able to describe and distinguish4 prezygotic and 4 postzygotic mechanisms that reinforce reproductive isolation Know the defining features of instantaneous speciation and the processes that cause it Know how hybridization followed by polyploidy can lead to speciation Know the defining features ofand the processes and mechanisms that lead to gradual speciation Be able to recognize and distinguish the de ning features ofallopatric and sympatric speciation and the conditions required for each to occur Be able to de ne and distinguish the geographic and peripheral isolates models of allopatric speciation Be able to describe the difference between the pattern of evolution suggested by Gradual speciation and Punctuated Equilibrium and what evolutionary mechanisms each emphasizes Understand how systematists use phenotypic similarity among species to reconstruct evolutionary history how convergent evolution presents a problem for this approach and how using similarity of molecules DNA sequences or amino acid sequences of proteins is similar to and different from using morphological similarity to infer evolutionary history Be able to define Coevolution and know how it is involved in the evolution of adaptations related to plantpollinator interactions Know what a pollen vector is what broad categories ofvectors are used by plants and the role of attractants and rewards in the evolution of ower diversity Know what a pollination syndrome is and why these evolve Know the definitions of each ofthe following Macromutation coevolution analogy homology vestigial phylogeny bottleneck founder effect nonrandom mating inbreeding allozyme genetic hitchhiking heterozygote advantage frequency dependent selection phenotypic plasticity binomial nomenclature Be able to do all ofthe problems on the Populations Genetic Problems worksheet Ecology Review part 2 1 What is the niche concept and how is it useful in the study of competition 2 What did Connel39s study in which he removed each of2 competing species of barnacles demonstrate Remember that he got different results for the two species 3 Be able to interpret Connel39s results in terms of the fundamental and the realized niche of each species 4 What is species diversity and how does it differ from species number 4 What is a food web and what does it tell you about the relationships among species in a community 5 How do competition and predation in uence species diversity in a community 6 What did Paine39s work involving the removal ofa predatory star sh from an intertidal community illustrate Would you expect the same result ifyou removed any predator from any community why or why not What are succession and the intermediate disturbance hypothesis and how are they related What processes cause species composition to change through time during succession 8 How is an ecosystem different from a community and what are the 2 major processes of interest in the study of ecosystems 9 Be able to describe and explain how energy enters and ows through a community Know the ultimate source ofthat energy 10 How is each of the trophic levels in a food chain de ned and what is the role of each in ecosystem processes 11 What processes determine how much energy enters and ows through a community What is ecological ef ciency and what determines how ef cient a species is 12 Be able to explain what factors do and do not limit the net primary productivity of terrestrial and aquatic ecosystems and the evidence that supports this conclusion 14 What determines the biome that is characteristic of a particular location on Earth 15 What determines the major zones of climate on Earth 16 Be able to explain the relationships between air temperature air density and the ability of airto hold moisture 17 Be able to explain exceptions to latitudinal determination of climate 19 Recognize the major features ofthe majorterrestrial biomes and the climate associated with each 20 What are the three levels of biodiversity and how is each relevant to Human welfare and economics 21 What is the evidence that there is a humancaused biodiversity crisis 22 What are the three main causes of extinctions due to Humans Definitions fundamental niche decomposer detritivore realized niche gross primary productivity community net primary productivity species diversity succession ecological ef ciency omnivore
