6319355864Key changes in the appearance of domesticated plants includebetter adapted to anthropogenic environments: more spatially and genetically different from wild plants, important phenotypic changes1
6319374511Commensal relationshipRelationship between two organisms where one organism benefits from the other without affecting it2
6319386693Historical ecologythe combination of the nature of the environment and the type of human society determine the impact to the environment3
6319400917Examples of resource managementBurning vegetation to enrich soil; construction of erosion. Control features; creating new irrigation canals4
6319412106Multiple Pathways to Domesticationdifferences in the nature of human animal relationship influenced the evolution of certain species that were predisposed to developing a close relationship with humans5
6319427535PossibilismNature limits what humans can do6
6319433338When did deforestation of Rapa Nui happen?Soon after colonization7
6319437081Demographic pressure hypothesisWhich hypothesis stats large populations cannot support themselves through hunting gathering activities8
6319462342Hunting by anatomically modern humans (AMH), especially in the last 65,000 years, is different from hunting by earlier forms of pre modern humans (such as Neanderthals) becauseOnly modern humans intensively hunt difficult-to-catch small game, such as rabbits and birds, as well as large animals.9
6320406044Key Terms10
6320451203Plasticitybuilt-in flexibility of an individual/group to adjust to changing conditions11
6320460878Environment* the changing complex of physical, cultural, chemical, and biological factors in which an organism or a community exits * various interactions: - biological: soil, plants, animals - non-biotic: climate, geology, water - culture: belief systems, social/economic system, political organization, personal attitudes12
6320516238Culturedynamic system of learned and shared behaviors, concepts, symbols, and beliefs that facilitates and provide meaning to a human's interaction with their environment13
6320585378Environmental Determinism- nature controls human actions - anthropogeoraphy; environmental condition are so limiting that they dictate how humans live. Biproduct of colonization-settlers started to recognize that they lived different lifestyles that were closely ties to the environment14
6320665094Possiblism- nature sets limits on human action - environments are limiting, but not determine how much humans live. Some behaviors are more "reasonable" than others depending on the environment. Not a theory, makes no predictions.15
6321887965Cultural Ecology- adaptations through cultural mean - More efficient behaviors selected for over time. Early proponent Julian Steward in 1930's and Marvin Harris in 1960's. - Key perspectives; nature eventually finds equilibrium, cultures adapt to produce payoff, good decisions, increase returns and bad decisions have high costs, decisions ar based off of short-term outcomes16
6321931913Political Ecology- judges the effects of daily behavior on'e's environment - Popularized in late 1970's/ early 1980s. Explore how regular social relationship (political, economic, social) influence people or their environment. Studies applied to resource management in contemporary societies and fate of small scale, indigenous communities faced with "modernization".17
6321972219Historical Ecology- Individuals important player in environment - outgrowth of cultural geography studies of 1970's. Historical events are key reason for change. Humans and environment are completely interrelated. - Key assumptions: *Humans primary cause in ecological changes *Humanly-induced change is not inherently good or bad *Sociopolitical and economic structure of society influence nature of environmental impact. *Combination of the nature of environment with structure of the society determines the type of environmental impact18
6322034600Equilibrium Systemhuman responses are (eventually) in sync with their changing environment (new condition = new ideas)19
6322049035Anthropogenic- anthro (human) + genic (produced) - human alteration or manipulation to their environment20
6322074962Resource Managementapplying selective planned, and/or organized exploitation strategies to an entity or feature of limit availability21
6322097622Domesticationa change in behavior, physiology, and/or genetics of species that reflect greater interdependence between people and animals22
6322110225Dispersala change in the natural distribution of specoes23
6322116909Active impacts- Purposeful or intentional effects - canals, quarry, coal - decisions made with imperfect or incomplete knowledge; long and short-term consequences of unknown24
6322261290Passive ImpactsIndirect or unintended effects - more profound negative; effects; may not have small scale effect25
6322378796Ritual & Environmental Impactsutilizes supernatural powers to protect important resources, highlights importance of resources and ensures proper use, maintains balance between human actions and environment26
6322412790Ecologically "Noble savage"- coined by explorer Marc Lescarbot in 1609. \ - Picked up by early environmentalists - Suggests: indigenous people lack many of the problems of European society, lived in harmony with the nature, and did not cause environmental damage like many state level societies27
6322451301Overkill hypothsis- Premise of human overkill been in existence since 1860s. - Strongest supporters are often researchers who work in other fields and areas28
6322591318Pacific Islandsmicronesia: settled first; closest to mainlands melanesia: settled second polynesia: settled last; furthest from mainlands29
6322605771Domesticatean animal or plant adapted to an intimate association with humans30
6322611810Mutalismrelationship in which both species derive benefit31
6322615974Simple foragingcollecting available wild resources without modification to environment32
6322622471horticulturegrowing domesticated fruit, plants, and vegetables in small gardens (small-scale farming)33
6322628152arigcultureproducing food, feed, fiber, fuel, and other goods by systematic raising of domesticated plants and animals (large-scale farming)34
6322654937teosinte (wild)- small and few kernels - seeds drop easily (shattering) - germinate and ripen at different rates35
6322665883Maize (domesticated)- large and many kernels - seeds do not drop - uniform germination and ripening36
6325265290ZoonoseInfectious disease that can be transmitted from other animals37
6325273956Commensal DomesticatesSpecies adapt to live with humans; dogs, cats, pigs, chicken, turkey38
6325291781People/reserchers39
6325308892Charles Darwin (1809-1882)developer of theory of evolution (natural selection-adaption to envrionment)40
6325319671John Muir (1838-1914)naturalist and preservationist, Sierra Club founded, lobbied for national parks41
6325331297George Marsh (1801-1882)author of Man and Nature, suggested human endanger their existence by irrational, exploitive use of nature42
6325374772Carl Sauer (1889-1975)geographer who laid theoretical foundation of cultural ecology, argued human societies need a responsible stewardship of the sustaining Earth.43
6325454125Paul MartinOverkill hypothesis; modern version of model most strongly developed.44
6325552675Marvin Harris, Roy RappaportModern View 1960's-1980's - Indigenous group have detailed knowledge of nature, use this knowledge to establish sustainable management system. - Key feature in native people's identity and political/ecological activism45
6325580367Jared Diamond, Shepard Krech, Raymond HamesCritics Response - Questioned idea of group-level adaptation - "conservation" not intentional; small population, limited technology, low demand, numerous examples of environmental damage46
6325614695V. Gordon ChildeEnvironmental change; recent revival of theory - Key issues; climate change cause plants/animals into close relationship with humans, agriculture response to either environmental degradation (food scarcity) or climate amelioration (new opportunities)47
6325643477Lewis Binford, Mark CohenDemographic pressure; developed in 1960s-1970s - Key issues; population pressure on wild food supply if there are >9 people/100km^2, more intensive use of animals and plants (including agriculture) needed to feed people48
6325675741Bryan Hayden, Jacque Cauvin, Ian HodderSocial Organization & Ideology; developed in 1990s - Key issues; predisposed to self-aggrandize and accumulate "wealth", periods of food abundance allows people acquire surplus, agriculture products were rare of delicacies and used to show social power & influence49
6325710551Melinda Zeder (2012)Multiple pathways to domestication; commensal domesticates, prey domesticates, directed domesticates.50
