First Midterm Flashcards
Iron’s affect on Global Warming
It cause cause an algea bloom in the water which causes a lot of CO2 to be sequestered, but that only works if CO2 is not respiraded and the biomass sinks to the ocean floor then
Physiological ecology
adaptations for resource acquisition and dealing with environmental stresses, its the study of animals decision making to
stuff like temperature or light intensity
Population ecology
population growth, distribution, and regulation for a certain species
population growth, life histories
community ecology
the study of different interactions of species
ecosystem ecology
the study of cycles of energy and matter through the abiotic and biotic parts of the ecosystem
Mauna Loa
Where the CO2 recordings happen in Hawaii
milankovich cycles
is the cycles caused by the natural tilt in the earth
pentagram
equals gigton which in 10^15 grams
The Suess Affect
It is how to prove that global warming is a really human caused and that is cause the ratio of C14 has gone down in the atmosphere even though, and C14 is radioactive so it has disappeared in the fossil fuels that we are burning, but it has increased in our atmosphere since 1950 because of the atomic weapons testing
natural green house affect
without it the earth would be -15 degrees celcius
Global warming on sea Rise
from melting land glaciers not icebergs and the sea water expanding because water that is warmer normally is less dense, they are afraid of the artic sheet melting but not really antartic sheet because it is so much colder but if they both melted we would be screwed
GPP
Is gross primary production, and is the total amount of carbon that is entering the ecosystems from the autotrophs, it is about twice that of the planets respiration
NPP
Is the net primary production which is GPP minus all the carbon that is released through respiration
productivity
is the influx of carbon per year
NEP
Net Ecosystem Production is the NPP minus the respiration from the heterotrophs
AET
Actual Evapo transpiration, which takes into affect both water availabilty, moisture in the air and temperature while PET only takes in temperature
Rainforest Limiting Nutrient
Is phosphorus, like the oceans where most of the world is nitrogen
Hypoxia
is the reduction of O2 that happens alot in water because there is over fertilization and all of that produces and algea bloom that when decomposes uses up all the O2 causing a dead zone
Bottom Up/ Top Up Cascade
The bottom up cascade is when the biomass is determinded by the lowest level on the food pyramid while top up cascade is the opposite
Assimilation Efficency
Assimilation over consumtion
Production Efficency
Production/ Assimlation
Growth Efficency
Production/ Consumption
Basal Metobolic Rate
As size increases the basal metabolic rate decreases
deposition
is the direct transfer of NO3 to the soil but it only makes up a small part of the nitrogen used by plants
nitrogenase
can turn N2 into amino for the plants to use and are found in the nodules of the plants
Mineralization
Turning the amino acids in a dead plant to a fourm of Nitrogen that can be used
denitrification
is when microbes turn the dead material back into N2
Carbon Content in Cultivated Area
When you cultivated the area it releases more carbon because the microbes can get to the dead organism better in the broken soil
Anthropogentic
human caused
Dark Cycle or Calvin Cycle
Is when they use the electrons from the light to cause a 5 carbon sugar to bind with another carbon using rubisco to fourm a 6 carbon sugar that then it quickly breaks down into 2 PGA 3 carbon sugars
Pep carboxylase
Is the enzyme that is used for the C4, that has a higher infinty to CO2 then O2 so it doesnt bind to O2 and that way
Compensation point and limitation of biochemical
things
Pmax=Imax
Light saturation point
Ruderal
fires
