Study Guide Part I – Biodiversity Unit Focus on chapters 1 thru 6 Chapter 1: flumering plants=300000 Vertebrate 50000 know approximately how many named species of living things there are on earth: o 1,500,000 know which groups are particularly diverse (no numbers needed) and approximately how many species of vertebrates, insects, and plants there are: o 50000 vertebrates, o Insects are the largest group, o 3000000 plants know that biodiversity can refer to: o habitat diversity, species diversity, and genetic diversity know the difference between species richness and species diversity o 1.2 pg 4 in book, o Richness: is the amount of one species in a habitat, where one species take over the other (in numbers) o Diversity: the amount of diff species in a habitat, know that diversity is not evenly spread out over the world and that tropical areas typically have more species than temperate areas: o tropical have more diversity then temperature areas know that a genome is all the genes of an individual and know that source of genetic variation among individuals is having different alleles (versions of a gene) for particular genes: o two diff questions, o Alleles are a different version of a gene it’s where we get our genetic variation. o Genome contains all the genes for an individual everything know that the two parts of a species name are the genus ( Homo ) and species (sapiens) e.g. Homo sapiens we are homo o he going to give you a name, ex. Homo, which of the following does it stands for: genus, o sapiens stand for: species Chapter 2: know that exposure to diverse environments was important in influencing Victorian naturalists and know where Darwin and Wallace travelled : o We are only looking at one person, the sample size is small, and an individual reacts differently to a certain situation. o exposer and diverse they travel and experience diff diverse inviroments….he went to o they traveled to Galapagos Island and traveled on a ship called The Bengle o We as human being think as a population, summing it up and generalizing. Know the two basic aspects of Darwin’s work (tree-thinking) o natural selection and descent with modification o Based on variation, which is a principle of natural science. Know the major pieces of evidence for evolution/speciation

o fossil record, island life, direct observation of speciation (bird example from lecture, lizard example) know that the standard deviation is a measure of the amount of variation in a population know that a phylogeny is a diagram showing

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
