|
Climate and important components of it |
Long term prevailing weather conditions in a given area
Important components: precipitation, temperature, sunlight, wind |
|
|
Macroclimate |
Patterns on the global, regional, and landscape levels |
|
|
Microclimate |
Fine localized level (i.e. Under a log) |
|
|
Abiotic factors
|
nonliving factors (i.e. light, water, nutrients, and temperature) that influence the distribution and abundance of organisms
|
|
|
Biotic factors
|
living factors - other organisms part of an individual's environment - that influence distribution and abundance of organisms
|
|
|
Biome
|
major life zones characterized by vegetation type (terrestrial biomes) or physical environments (aquatic biomes)
|
|
|
ecotone
|
the area of intergradation occurring when one biome fades into another (i.e. tropical forrest fades into high mountains)
|
|
|
canopy
|
highest layer of vertical layering in terrestrial vegitation
|
|
|
disturbance
|
an event that changes a community, removing some of its organisms and altering resource availability (i.e. storm, fire, human activity) periodic disturbance is sometimes beneficial |
|
|
photic zone
|
upper layer of aquatic biomes where there is sufficient light for photosynthesis
|
|
|
aphotic zone
|
lower layer of aquatic biomes where little light penetrates
|
|
|
pelagic zone
|
aphotic + photic
|
|
|
abyssal zone
|
part of the ocean that is 2000-6000m below the surface
|
|
|
benthic zone
|
bottom of each zone (deep and shallow); made up of sand, organic, and inorganic sediments
|
|
|
benthos
|
communities of organisms found in the benthic layer they feed on detritus: dead organic matter that falls from surface waters of photic zone |
|
|
Thermocline
|
narrow layer of abrupt temperature change dividing upper warm layer from deeper cold layer
|
|
|
turnover
|
occurs during spring; deeper, nutrient rich waters rise to surface and upper oxygenated waters fall to bottom
|
|
|
dispersal
|
movement of individuals or gametes away from their area of origin or from centers of high population density
|
