5433322119PopulationSecond level of complexity after the individual, composed of all individuals of a single species that live and interact in a specific area.0
5433322120CommunityThird level of complexity, all populations in da area. "How different species interact with each other."1
5433322121BiomeComplexity level 4.5, group of ecosystems.2
5433322122EcosystemComplexity level 3, communities exist in here, biotic+abiotic components in in a particular location.3
5433322123BiosphereComplexity level 5, Da livin world.4
5433322124DynamicConstantly changing, used to describe populations.5
5433322125Population ecologyThe study of factors that cause populations to increase or decrease.6
5433322126Population sizeTotal number of individuals within a defined area at a given time.7

5433322128Population distributionHow individuals are grouped in respect to each other.9
5433322129population Sex ratioRatio of Males:Females10
5433322130Population Age StructureHow many individuals fit into particular age categories.11
5433322131Density Dependent factorsFactors that impact survival and reproduction that are influenced by population size.12
5433322132Limiting resourceResource that is lacking and causes population decreases as a result13
5433322133Carrying capacityHow many individuals an environment can sustain based on resources. Denoted as K14
5433322134Density independent factorsFactors that affect survivability that is not affected by population of a species, like a tornado.15
5433322135Population growth modelsMathematical equations that can be used to predict population size at any moment in time.16
5433322136Growth rateNumber of offspring an individual can produce in a given time period minus the deaths of the individual and its offspring.17
5433322137Intrinsic growth rateMaximum potential of growth, even under perfect conditions.18
5433322138Exponential growth model.Nt=N0e^rt19
5433322139Jshaped curveThe curve of an exponential graph.20
5433322140Logistic growth modelA model of a population that shows initial exponential growth and then a plateau.21
5433322141S Shaped curveCurve of the logistic growth model22
5433322142Overshootwhen a population grows to a size that the environment can not sustain.23
5433322143Die-offEffect of an overshoot when the extra individuals die from lack of food or other resources. Die offs and overshoots can be regular in an environment)24
5433322144K-selected speciesSpecies that have a small intrinsic growth rate so that when they reach the carrying capacity they do not have large die-offs if any because they had approached the carrying capacity gradually. Usually large species with long lives.25
5433322145r selected speciesSpecies that breed very quickly, and that have large population fluctuations because of that.26
5433322146Survivorship curvesPatterns of survival that are plotted on these curves. Large species with long lives such as elephants and humans fit into type 1 survivorship curve, mosquitos and fruit flies fit into the type 3 survivorship curve and coral and squirrels that live kinda lengthy lives fit into type 2 survivorship curves.27
5433322147CorridorsStrips of habitat that allow connectedness of species from population to population.28
5433322148metapopulation2 distinct populations that are linked by occasional individuals mingling between the two groups. Protects species from extinction29
5433322149Fundamental nicherange of abiotic conditions that a species can tolerate30
5433322150Able to disperseSpecies need to be able to get to another physical location without human intervention to be present in an area.31
5433322151Competition, predation, mutualism, commensalismSelf explanatory, categories of interaction between species.32
5433322152Community ecologyStudy of interspecies interactions33
5433322153Competitive exclusion principletwo species that are competing for the same resource cannot coexist34
5433322154Resource partitioningTwo species dividing a resource based on differences in the species behavior or morphology.35
5433322155Temporal resource partitioningSpecies using same resource but at different times.36
5433322156Spatial resource partitioningReducing competition by using different habitats.37
8122409585clumped distributiontype of population distribution that helps protect a population from predators.38
8122443920uniform distributionfound when animals are distributed equally in an ecosystem, due to limited resources or territories39
8122789029rrate of growth, found by taking the number of individuals added and dividing by the total population (f-i/i)40
81228264920.3 (3,000/10,000)In a colony of 10,000 penguins, 3000 are hatched. What is r?41
812283733612,000 or (0.2 X 10,000) + 10,000If a colony of 10,000 penguins has a growth rate of 0.2, what will the population be at the end of the year?42
8122853684CBR=68If Hillia has a population of 10,000 and there are 680 births during a year. What is the crude birth rate for Hillia?43
8122868679False, Hawks are K selected speciesHawks are r selected species. True or False44
8122877166carrying capacityr selected species will exhibit boom and bust growth cycles and overshoot what?45
8122882315J Curve or exponential growthwhat type of growth curve do r-selected species generally exhibit?46
8122886245TrueT or F, Under ideal conditions most animals can grow exponentially47
8122890479density dependentwhen a predator feeds on the most abundant prey this type of predation is48
8122895477density independentFrost is what type of density factor?49
81229064201. predators find prey easier 2. predators are able to have more offspring under these ideal conditions 3. predator nutrition is better 4. it may be easier to catch prey since they may weaken due to overshooting their carrying capacity.In population studies we see that as prey population increases, often predator populations increase. What are some reasons for this?50
8122919670mutualism, predation, competition, comensalismGive examples of interspecific interactions.51
8122927045parasitism, predationsymbiotic relationship where one is harmed and the other benefits52
8122938228both species are negatively affectedinterspecific competition always results in what53
8122941617chemical secretions, mimicry, warning colors, camouflagehow do prey evolve to evade predators?54
8122952608resource partitioningOn Daphne Island in the Galapagos, finch species evolved to feed on varying sizes of seeds from the same tree, this is an example of55
8122955936competitive exclusionwhen two species compete for the same resource, one species does not survive, this is called56
8122959329habitat fragmentationwhen areas where species live are broken up into smaller areas that are not connected we call this57
