An organism that can survive during the adult stage

This preview shows page 7 - 10 out of 16 pages.

An organism that can survive during the adult stage but cannot produce any progeny in that environment will fail to become established in that habitat Climate Vs weather Climate refers to longer times and wider areas Weather is the state of the atmosphere to the degree that it is hot or cold, wet, or dry, calm or stormy, clear or cloudy Biotic Pump Hypothesis

Natural forests create and control ocean to land winds, bringing moisture to terrestrial habitat Winds blow from regions of high air pressure to low air pressure As water vapor condenses, the # of gas molecules condenses into drops o Condensation above natural forests create a persistent low pressure zone Natural forests are critical for sustaining rainfall o A positive feedback loop What Drive Earth's Climate? o Solar radiation o Earth's relative position to the sun: tilt, rotation, revolution o Atmospheric gases: H2O, CO2, CH4, N2O, O3 o Milankovitch cycles inflluence the episode nature of earth's glacial and interglacial periods These cycles describe: eccentricity, axial tilt, and precession Cycles create alterations in seasonality of solar radiation reaching earth's surface Periods increased or decreased of solar radiation directly influence the Earth's climate system o Additional climate factors: global ocean currents and global air circulation Ocean Circulation o North Atlantic circulation is driven by warm, salty water moving northward where it cools, becomes denser and sinks to the ocean bottom where it then flows south This action pulls surface water from the south giving rise to the gulf stream o Global Conveyor Belt is part of the process that drives the world's oceanic currents o Increase in global temperatures cause Greenland ice sheets to melt meaning water is becoming less dense and not sinking Consequently, the gulf stream is slowing down Slowdown in Atlantic Ocean Circulation- Gulf Stream o Bermuda gets colder o Colder waters likely to kill most or all of corals surrounding Bermuda After death of corals, Bermuda's protection from high energy wave action and severe tropical storms will be removed ECOLOGY: THE BIOSPHERE AND ABIOTIC CONDITIONS Limiting factors of populations o The determine the carrying capacity of an environment for a species o Density Dependent: Competition Predation Parasitism and Disease o Density Independent Natural Disaster Unusual Weather Population regulation o What factors might decrease births, increase mortality, or increase dispersal out of an area when density decreases?????

(DENSITY INDEPENDENT FACTORS) Limiting resources ( competition Places to live Shelter Food Water Pathogens (disease) Transmission rate increases with density Predators Easier to detect/ capture prey when density is high Parasites Easier to detect/ find host when density is high o Density Dependent Population Regulation Negative feedback loop
