-
factors affecting temperature
what aspects of topography affect temperature
- -slope aspecy
- -degree of slope (tilt angle)
- -cold-air drainage
-
factors of temperature
topography slope aspect
a flat surface will generate a higher temperature
-
factors of temperature
degree of slope
the more a slope tilts the more temperature it will generate
-
factors of temperature
cold air drainage
- when you stick your hand out the window
- -cold air collects in low areas
-
microclimate
ground color
darker colors absorb more visinle light
-
microclimate
vegetation
shading also reduces temperature and temperature fluctuations (shrubs in desert)
-
microclimate
water depth
deeper water has less temperature variation
-
microclimate
water flow
mixing causes temperature to be more constant
-
temperature distribution in organisms
temperature is a critical variable affecting what
the distribution of organisms (the cactus in desert)
-
temperature distribution in organmisms
in organisms that have a large distribution, variations in temperature can what
result in the development of locally adapted populations called ecosystems
-
temperature effects on photosyntesis
extreme rates usually what
reduce the rate of phptosynthesis
-
temperature effects on photosynthesis
different plants have different what
optimal temperatures
-
temperature effects on photosynthesis
what is acclimation
- physiological changes in response to temperature
- -a plant may shift its optimal temperature for photosynthesis to match seasonal changes in environment
-
temperature effects on microbial activity
like plants micrpbes (bacteria and fungi) do what in reference to optimal temperature
they have an optimal temperature for growth and activity and some are able to accumulate to variations in temperature
-
temperature effects on animals
are animals able to acclimate
limited ability
-
temperature effects in animals
what is the effect of temperature affected by in animals
- if they are
- -ectothermic- relies mainly on external energy sojrces to regulate body temperature
- -endothermic-relies heavily on metabolic energy to regulate body temperature
-
temperature effects on animals
ectothermic
poikilothermic
-
temperature effects on animals
endothermic
homeothermic
-
energy balance
formula for energy balance
- some men cant do certain virtues religiously everyday
- hs=hm+-hcd+-hcv+-hr-he
- hs-total heat stored in an organism
- hm- gained via metabolim
- hcd-gained/lost via conductiom
- hcv-gained/lost via convection
- hr-gained/lost via electromagnetic radiation
- he-lost via evaporation
-
temperature regulation in plants
formula
some cant do certain virtues religiously everyday
-
temeperature regulation in plants
whats a benefit to having lighter leaves
have higher reflection that dissipates heat by hr
-
temperature regulation in plants
vertically oriented plants have what advantage
dissipate heat by hr
-
temperature regulation by plants
dissipating heat by he is effected when
when there is sufficient water
-
temperature regulation in plants
convection
open growth forms have more exposure to wind and more energy lost
-
temperature regulation in plants
what does cushion growth intercept, gain
hr and hcd
-
temperature regulation by ectothermic animals
formula and what they can do for each
- hs=hcd+-hcv+-hr-he
- hcd-stilting, basking in the sun
- hcv-stilting increases wind exposure
- hr-basking, seeking shade, burrowing, variation in body color
- he-evaporation not an important pathway of heat dissipation for ectoderms
-
temperature regulation for endothermic animals
formula
hs=hm+-hcd+-hcv+-hr-he
-
temperate regulation by endothermic animals
what is especially important for endothermic animals
heat gained or lost frlm metabolism
-
temperature regulation for endothermic animals
what is the thermal neutral zone
the range of environmental temperature over which the metabolic rate of homeothermic animals does not change.
