EcologyWhat is ecology?Ecology is the scientific study of interactions between ___________term ecology comes from the Greek oikos, _______, and logos, to studybiotic and abiotic factorsWhat are biotic factors? Give examples.What are abiotic factors? Give examples.climateWhat is climate?What abiotic factors are the major components of climate?What effects do bodies of water have on climate?What effects do mountains have on climate?Include descriptions of how elevation affects temperature, and of rain shadows.What effects do seasons have on climate?Describe what causes seasons; include the terms solstice and equinox in your description.biomesWhat are biomes?aquatic biomesList the major aquatic biomes and their defining physical features (there are 8, giving you space here).define the following: photic zone, aphotic zone, benthic zoneDescribe the process of turnover in a lake, and why it is important.What is eutrophication, and what are some likely consequences of it?terrestrial biomesList the major terrestrial biomes and their characteristic vegetation types and climate (there are 8).define the following: climograph, ecotoneBe sure that you can interpret a climograph (like figure 52.20).population ecologyPopulation ecology is the study of populations in relation to __________A population is:define the following: density, dispersion, rangeHow does the mark-recapture method to estimate population size work? Include the formula and definition of the terms in the formula.What is demography?define and be able to use/interpret:life tablessurvivorship curvesreproductive tablesdefine and be able to use/interpret the exponential population growth modeldefine and be able to use/interpret the logistic population growth modeldefine and understand the terms K and rdescribe K-selection and r-selectionWhat sort of life tables and survivorship curves would you expect for each type?give examples of organisms of each typeIf given a typical life history for an organism be able to categorize it as K-selected and r-selected.List and describe six density-dependent factors known to affect population growth rates.Describe how population cycles may be linked between predators and their prey.Human population history and future Be sure that you understand figures 53.22-26.What was industrial revolution and how did it affect human population growth?What is the demographic transition and how does it affect human population growth?What is the global carrying capacity for humans?community ecologyCommunity ecology is the study of __________A biological community is:describe the following interspecific interactions in general terms of the +/-/0 systemcompetitiondefine the terms (ecological) niche, resource partitioning, and character displacementpredationDescribe how these defenses can help animals avoid predation:camouflagewarning colorationBatesian mimicryMüllerian mimicryherbivoryparasitismmutualismWhat is the difference between obligate and facultative mutualism?commensalismWhat is symbiosis? Which interspecific interactions are types of symbiosis?What is keystone species and a pivotal niche?What is a food web? How do energetic limits affect food webs/chains?Describe ecological succession, primary succession, and secondary succession.ecosystemsDiagram the biogeochemical cycles of watercarbonnitrogenphosphorusDescribe how biomagnification (biological magnification) of a toxin works in an ecosystem.How we almost killed ourselves: the ozone hole story (see fig 55.25)Describe the importance of the ozone layer.Describe how human activities led to depletion of the ozone layer.Describe what humans have done about the depletion of the ozone layer.How we still might kill ourselves: global warming (see fig 55.21)Describe the greenhouse effect and why CO2 is called a greenhouse gas.Describe how human activities increase CO2 in the atmosphere, the logic behind how that leads to global warming, and the evidence that global warming is occurring.Describe what effects global warming may have. What is the feed-forward effect of thawing tundra?Describe what humans have done about the global warming.Define ecosystem biodiversity, species biodiversity, genetic biodiversityDescribe the value of biodiversity inmaintaining the global ecosystem and biogeochemical cyclesproviding unique resources such as food, remediation, drugsintrinsic value of biodiversityThe sixth extinction, or how we are killing lots of things and perhaps ultimately ourselves as well.What is habitat loss and how is it affecting life on Earth today?What are introduced species and how are they affecting life on Earth today?What is overexploitation and how is it affecting life on Earth today?What is the sixth extinction? What can humans do about it? ................
