Study Guide Part I – Biodiversity Unit Chapter 1: flumering plants=300000 Focus on chapters 1 thur 6 Verterbrate 50000 -know approximately how many named species of living things there are on earth 1,500,000 -know which groups are particularly diverse (no numbers needed) and approximately how many species of vertebrates, insects, and plants there are 50000 verterbrates, largest group of insects, 3000000 -know that biodiversity can refer to habitat diversity, species diversity, and genetic diversity - -know the difference between species richness and species diversity 1.2 pg 4 in book, ecology and the graph about the mouse, know the diff between the richness and the diversity. Diversity: the amount of diff species in the a habitat, and richness is the amount of one species in a habitat, where one species take over more than the other. -know that diversity is not evenly spread out over the world and that tropical areas typically have more species than temperate areas : 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 : two diff questions, alles is a diff version of a gene its where we get genetic variation. Geno 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 he going to give you a name, ex. Homo, which of the following does it stands for….genus, what does sapian…species Chapter 2: -know that exposure to diverse environments was important in influencing Victorian naturalists and know where Darwin and Wallace travelled : we are only looking at one person, the sample size is small, an individual reacts differently to a certain situation. ------exposer and diverse they travel and experience diff diverse inviroments….he went to gullupmos island and traveled on a ship called the bengle - We as human being think as a population ….suming it up and generalizing. - know the two basic aspects of Darwin’s work – natural selection and descent with modification (tree- thinking) based on variation….which is a princiole of natural science. -know the major pieces of evidence for evolution/speciation – fossil record, island life, direct observation of speciation (bird example from lecture, lizard example) t -know that the standard deviation is a measure of the amount of variation in a population -know that a phylogeny is a diagram showing =evolutionary relationships

    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.
