You should know the information in the animal study guide charts that were e-mailed this week. link Some questions will ask you to identify the phylum/class of animal base don its features, some questions will ask you to determine which two animals are most closely related. Be able to explain the major transitions in the evolution of animals. Compare the transition from an aquatic lifestyle to a terrestrial lifestyle in animals with the same transition in plants. BIOLOGICAL COMMUNITIES & SPECIES INTERACTIONS - S &T CH. 46 – except succesion What’s a habitat? What’s a niche? What does Gause’s Rule say about ecological niches? What characteristics of islands help predict species richness? Is species richness the only measure of biological diveristy? What is resource partitioning and why does it occur? Do predators control population size of their prey? Do prey control population size of their predators? What determines the number of species globally? Define, understand, and give examples of: autotroph heterotroph symbiosis interspecific competition intraspecific competition interference competition exploitation competition mutualism commensalism predation parasitism parasitoid predation vs. parasitism indicator species keystone species coevolution mimicry warning coloration What are producers and what is their role in an ecosystem? What are consumers and what is their role in an ecosystem? Describe the various trophic levels in an ecosystem. Why are decomposers so important? Explain the difference between an autotroph and a heterotroph. What is a food chain? What is a food web? Is energy transfer between trophic levels 100% efficient? If not, how efficient is it and what happens to the energy that is not transferred to the next trophic level as biomass? What is biomass? Why are there rarely more than 3 trophic levels in a food chain? What is net primary production? What is gross primary production? What is meant by the statement that energy flow through ecosystems is unidirectional but matter is cycled? CONSERVATIONS ISSUES S&T CH. 27, PP. 812 - 817, PL CH. 6, 7, HANDOUTS Describe the major vegetation types found in southern California, their features and adaptations of plants and animals living within, and conservation challenges - Pt. Loma CH 4-5 – also see Some notes on Point Loma Book Chapters 4 & 5 (http://homework.sdmesa.edu/lseiger/courses/naturalhistory/ptloma45notes.htm) What is a clear cut? What is biodiversity and how can it be neasured? Are all exotic species invasive? Discuss how San diego gets its fresh water. Discuss the three major threats to San Diego’s fresh water supply. Discuss potential solutions to the problem. Do exotic species become invasive due to their features, the features of the habitat they invade? Explain. Explain: exotic, alien, nonnative, introduced vs. native, endemic; naturalized For what reasons do humans have such a large (and increasing) impact on the environment? Give 2 examples of biological invasions and their impacts. Give an example of how each element of "HIPPO" causes species extinctions and or environmental damage. Give an example of how habitat loss, habitat fragmentation, overpopulation and overcconsumption cause species extinctions and or environmental damage. Has commercial fishing in the oceans increased, decreased, or stayed the same sinceWW2? Has there been significant deforestation in the US? How are exotic species introduced? How do human activities exacerbate the greenhouse effect and what how does this impact climate? What are some of the actual and potential repercussions? How does San Diego County compare to other counties in the US in terms of number of federally listed endangered animal and plant species? Why? How does the US compare to other countries in terms of total energy consumption? In terms of per capita energy consumption? How is erosion related to deforestation? Humans use natural resources and generate pollutants because of (a) increasing population size, (b) lifestyle, (c) both, (d) none of the above. What are the 2 major causes of animal extinctions associated with human activities? What are the effects of habitat fragmentation? What does it mean that a species is “listed” as endangered? What does the acronym HIPPO stand for? What factors influence the number of species on islands and how is this important in terms of conservation of habitat? (island biogeography) What is bycatch? What is the difference between habitat loss and habitat fragmentation? What is the edge effect? What is the greenhouse effect? Is it a natural phenomenon? Why are invasive exotic species a problem? Why is Rachel Carson an important historical figure?
