    Ecology

    補足(例文と訳など)

    答え

    • The study of the distribution and abundance of organisms and their interactions with the world and others

    解説

  • 2

    Niche

    補足(例文と訳など)

    答え

    • Describes all the biotic (living) and abiotic (nonliving) resources in the environment used by an organism.

    解説

  • 3

    Size (of a population)

    補足(例文と訳など)

    答え

    • Total number of individuals in the population (Represented by N)

    解説

  • 4

    Habitat

    補足(例文と訳など)

    答え

    • Place where organisms live. Can be described through temperature, soil quality, water salinity.

    解説

  • 5

    Age Structure

    補足(例文と訳など)

    答え

    • Describes the abundance of individuals of each age; Often shown in age structure diagrams.

    解説

  • 6

    Biosphere

    補足(例文と訳など)

    答え

    • This is composed of all the regions on the earth that contains living things. IE soil, oceans, lower 10 km of the atmosphere.

    解説

  • 7

    Type III Survivorship Curve

    補足(例文と訳など)

    答え

    • Curve that describes species in which most individuals die young, with only a few organisms surviving long enough to reproduce and beyond. (oysters, plankton)

    解説

  • 8

    Density-Dependent Factors

    補足(例文と訳など)

    答え

    • [a limiting factor] Agents whose limiting effect becomes more intense as the population density increases (IE parasites/disease, resources, toxic effect of waste products, and predation)

    解説

  • 9

    Exponential Growth Factors [of humans] include

    補足(例文と訳など)

    答え

    • Increase in food supply, reduction in disease, reduction in waste, expansion of habitat

    解説

  • 10

    Exponential Growth

    補足(例文と訳など)

    答え

    • Pattern of population growth that occurs whenever the reproductive rate is greater than zero. (Forms a J-shaped curve when graphed)

    解説

  • 11

    Logistic Growth

    補足(例文と訳など)

    答え

    • Pattern of population growth that occurs when limiting factors restrict the size of the population to the carrying capacity of the habitat.(Forms an S-shaped curve [a sigmoid] when graphed.

    解説

  • 12

    Limiting Factors

    補足(例文と訳など)

    答え

    • Elements that prevent a population from attaining its biotic potential.

    解説

  • 13

    r-selected species

    補足(例文と訳など)

    答え

    • Species that exhibit rapid growth (J-shaped curve), where opportunistic species (grass/insects) quickly invade habitats, reproduce, and die. Offspring are small, mature fast, and require little care

    解説

  • 14

    Dispersion

    補足(例文と訳など)

    答え

    • Describes how individuals in a population are distributed. (IE clumped [people in cities], uniform [trees in orchards], or random [trees in forest])

    解説

  • 15

    Population

    補足(例文と訳など)

    答え

    • Group of individuals all of the same SPECIES LIVING in the SAME AREA.

    解説

  • 16

    Population Cycles

    補足(例文と訳など)

    答え

    • Fluctuations in population size in response to varying effects of limiting factors

    解説

  • 17

    Equation for the growth of a population

    補足(例文と訳など)

    答え

    • r=(births - deaths)/N where r=reproductive/growth rate and N=initial population size

    解説

  • 18

    Factors that may affect biotic potential

    補足(例文と訳など)

    答え

    • Age to reproduce, Clutch size (# of offspring produced at reproduction), Frequency of reproduction, Reproductive lifetime, and Survivorship of offspring long enough to reproduce.

    解説

  • 19

    Density (of a population)

    補足(例文と訳など)

    答え

    • The total number of individuals per area of volume occupied. (IE 100 mice/km^2)

    解説

  • 20

    Density-Independent Factor

    補足(例文と訳など)

    答え

    • [a limiting factor] Occurs independently of the density of the population (IE natural disasters, climate change)

    解説

  • 21

    Community

    補足(例文と訳など)

    答え

    • Group of populations living in the same area.

    解説

  • 22

    Carrying Capacity

    補足(例文と訳など)

    答え

    • Maximum number of individuals of a population that can be sustained by a particular habitat.

    解説

  • 23

    Population Ecology

    補足(例文と訳など)

    答え

    • Study of the growth, abundance, and distribution of populations.

    解説

  • 24

    Type I Survivorship Curve

    補足(例文と訳など)

    答え

    • Curve that describes species where most individuals survive to middle age. After that, mortality is high. (humans)

    解説

  • 25

    k-selected species

    補足(例文と訳など)

    答え

    • Species where population size remains constant (IE humans) and produce a small number of relatively large offspring that require much care until maturation.

    解説

  • 26

    Biotic Potential

    補足(例文と訳など)

    答え

    • Maximum growth rate of a population under ideal conditions, with unlimited resources and without growth restrictions

    解説

  • 27

    Human Population Growth

    補足(例文と訳など)

    答え

    • Growth that began 1000 years ago, grew exponentially.

    解説

  • 28

    Survivorship Curves

    補足(例文と訳など)

    答え

    • Describes how mortality of individuals in a species varies during their lifetimes.

    解説

  • 29

    Ecosystem

    補足(例文と訳など)

    Type II Survivorship Curve

    補足(例文と訳など)

    答え

    • Curve that describes organisms in which the length of survivorship is random, death likelihood is the same at any age. (rodents and hydras)
