  1. shelfords law of tolerance

    Factors controlling the distribution of biota…behavioral
  2. Fletcher's experiment

    Factors controlling the distribution of biota…biotic forces
  3. same amount of oxygen at sea level just less pressure pushing it into lungs
    • Temp of eggs gender determination
    • sigmoid shaped curve
    • poikilotherm vs homeothermal
    • poikilotherm changes with environment
    • diamondback terrapins
    • *estuary
    • * only turtles that can live in brackish water
    • change in temp and salinity
    • map turtles- soft shell
    • Niagara river
    • stay under ice
    • clolaca/bimodal
    • Hoodoos in Bryce canyon
    • microhabitat example
    • big change in temp in small distance
    • ecological island
    • Death Valley
    • white from salt
    • less then 2 inches of rain a year
    • 134 degrees
  4. large animal species with widespread popular appeal that environmental activists use to achieve environmentalist goals
    charismatic megafauna
    • Convection cells
    • adiabatic heat/cooling
    • Hadley cells
    • latitude effects on clime
    • Thermal inertia
    • water warm/ retaining heat
    • water takes a long time to heat and then retains the heat
    • rain shadows
    • slope aspect
    • more clouds the colder it is
    • cold air=less moisture=less dense
    • * latitude effects on climate
    • * Hadley cells
    • * Hadley cells and biomes = climate
    • dry areas: 30 & poles
    • wet areas: equator & 60
    • * rain shadows & slope aspect
    • * aspect=dominate slope direction
    • N-facing(left side) cooler, more moist, less sunlight
    • Zebra muscles
    • * transplants
    • * invasive, disrupts community
    • * ecological niche
    • * veligers
    • * ballast water
    • *filter feeders
    • Zebra muscles
    • * transplants
    • * invasive, disrupts community
    • * ecological niche
    • * veligers
    • * ballast water
    •  multiply quickly and blanket areas they invade, clog pipes and motors
    • Gypsy moths
    • * transplants
    • * invasive, disrupts community
    • * ecological niche
    •  tree defoliators of Aspen and oak
    • Great-tailed grackles
    • * transplants
    • * invasive, disrupts community
    • * ecological niche
    • large flocks, noisy, poop everywhere
    • energy per area: more at equator bc less atmosphere
    • 60 + has low energy from sunlight bc more atmosphere/thicker to go through
    • *seasons are caused by tilt of earth, not the distance of the sun
    • *vernal(spring) & autumn equinox: sun directly on equator
    • *even amount of sunlight on all earth
    • *thermocline
    • *ice floats bc less dense then 4 degrees
    • *isothermal-same temp-spring/autumn
    • * cold water holds more O2

    • *silent spring
    • *started environmental movement
    • *dead birds ate insects w/pesticides in them
    • *biological magnification
    • *wind sheer
    • *wind can change the morphology of plants
    • death valley
    • salt deposits
    • death valley
    • salt deposits
