Odum (Readings) Flashcards
FRAGMENTATION
Breaking up a larger/intact habitat into smaller, dispersed patches
PERFORATION
Creating holes within an essentially intact habitat
SHRINKAGE
Decrease in size of one or more habitats
ATTRITION
Disappearance of one or more habitat patches
BEARING CAPACITY
Soil’s resistance to penetration from a weighted object, e.g. building foundation
ANGLE OF REPOSE
Angle at which soil can be easily inclined and beyond which it will fall
WATER TABLE
The upper boundary of the zone of groundwater; the top of unconfined aquifer
AQUIFER
A permeable geological stratum or formation that can both store and transmit groundwater in significant quantities
WATERSHED
A geographic area of land bounded by topographic features and height of land that captures precipitation, filters and stores water and drains waters to a shared destination.
Includes birds and mammals associated with crop fields, meadows, pastures, non-forested lands. Habitat elements essential include
a. grain and seed crops
b. grasses and legumes
c. wild herbaceous upland plants
d. hardwood woody plants
OPENLAND WILDLIFE
These species need
a. grasses and legumes
b. wild herbaceous upland plants
c. hardwood woody plants
d. cone-bearing shrubs such as pines
WOODLAND WILDLIFE
Include birds, mammals needing
a. wetland food plants or wild herbaceous plants of moist to wet sites, excluding submerged or floating aquatic plants
b. shallow water dev’t with water impoundments not deeper than 5 ft.
c. excavated ponds with ample supply of water at least one acre and ave. 6 ft. depth
d. streams
WETLAND WILDLIFE
Climate Pattern: SPATIAL
Tropical/temperate/polar regions
Climate Pattern: TEMPORAL
Hot-cold or wet-dry seasons
ANGLE OF INCIDENCE
Affects area over which energy of light is dissipated, the depth of area penetrated, and amount of light energy that is reflected by airborne particles w/out reaching surface
ADIABATIC COOLINIG
When air at equator cools as it rises resulting in lower capacity to hold water, thereby raining heavily at equator
ADIABATIC WARMING
When the circulation pattern of hadley cells causes rising air to spread in upper atmosphere, cool and eventually drop back to surface in a water-depleted condition that allows it to gain capacity to hold water as it drops and warms the air
SAND DUNES
Mounds or ridges of sand deposited by wind
EARTH’S CRUST AND UPPER MANTLE: 80-100 KM THK. RIGID PLATES
THEORY OF TECTONIC PLATES
Move and continuously over the interior of the earth. Movement results in pressure, separation, or sliding at plate edge. As plates move, strain accumulates causing faults along plate boundaries to slip abruptly. The result of stress is earthquake
ELASTIC REBOUND THEORY
Different displacements within the earth’s crust create elastic strains greater than the rock can endure. Riptures occur and the rock rebounds along the fault until the strain is partly or completely relieved
OTHER CAUSES OF EARTHQUAKE
Volcanic activity, underground nuclear explosions, injection of waste liquid into susceptible rock strata, and in some cases, the weight of newly constructed large dams, and reservoirs
MERCALLI SCALE (MM)
Widely used scale to measure intensity
TECTONIC CREEP
Slow differential slippage of 2 sides of fault
