ecology
is the scientific study of the interactions between organisms and the environment
Global Ecology
is the study of the exchange of energy and materials across the biosphere
Biosphere
the regions of the surface and atmosphere of the Earth where living organisms exist
Landscape Ecology
is the study of the exchange of energy, materials, and organisms across multiple ecosystems
Ecosystem Ecology
is the study of energy flow and chemical cycling between organisms and the environment
ecosystem
is the community of organisms in an area and the physical factors with which those organisms interact
population ecology
is the study of the factors that affect population size and why it changes over time
population
is a group of individuals of the same species living in an area
organismal ecology
includes the physiological, evolutionary, and behavioral ecology of how an organism's physiology, structure, and behavior meets environmental challenges
As water evaporates from the tropics,
the air rises until the water becomes precipitation, and the high-altitude air masses absorb that precipitation and descend to the earth, creating global air patterns
climate
which is the long-term prevailing weather conditions in an area
climate
the most significant factor on the distribution of organisms on land and in the oceans
important components of climate
Temperature, precipitation, sunlight, and wind
Macroclimate
describes patterns on the global and regional level, while microclimate describes fine, localized patterns on a community level
the input of solar energy and Earth’s movement in space
Global climate patterns are determined by
Climate patterns include seasonal variation and are modified by large bodies of water and mountain ranges
Regional and Local Effects on Climate
The Earth’s tilted rotation and passage around the sun causes seasonal cycles ● Solar radiation, day length, and the angle of the sun also influences local environments ● Wind patterns can upwell cold water in oceans by altering ocean currents ● Wet and dry seasons result from the angle of the sun changing
Seasonality
Ocean currents influence climate along the coasts of continents by heating or cooling overlying air masses that pass across the land ● Coastal regions are wetter than inland regions, resulting in more dense vegetation ● Due to the high specific heat of water, oceans and lakes maintain the climates of nearby land ● Cooler air from the land at night replaces the warmer air above bodies of water, and it causes inland areas to become warmer
Bodies of Water
abiotic factors
which are the small-scale differences in chemical and physical attributes of an environment, such as temperature, light, and water, influence the distribution and abundance of organisms
