- talking about man
- talking about how humans spread throut the world
- also talking avout how we killed species off
- they are creating artificial evolution
- we have extincted many organisms
- big 5 extiction events
- this book will talk about how we are causing the 6 extinction
- beginig talkjs about how it came
- 2nd part will talk about what will hapen
- 8
- emblematic: represetitive

- castello aragonse is small italian island
- plate tectonics volcanic?
- bad for acidification acid rain connection
- special bacteria thing that eats te co2 and poops stone
- the acid kills of sstuf on seawead so it looks greber possible indicator tool?
- what are limpets
- hapless:unlucky
- green house effect is serioius and i ncreasing
- we are addin co2 to ocean by adding to greenhouse effect
- scale is logarithmic so semengly small chssnge
- very serious progection
- 75
- study first dine in lab but acid from vents allows natural expeimnet
- shows that with progected acidiity organisms will start to die off
- will c ause ecosystem and food web to crash
- the bacteria stuf that has calcites shells is affected bittom of foodweb so big impact
- important sea snail fopr bigger predators absent
- sma;ll plankton excell and take nutrients whic is bad for other organismas
- 77 big factor in extinctioin of ocean life in other extinctions
- acidifcation affects ability to metabolize ezme activity and protiuen function
- 78
- calcifyer are mad e even harder to cary out process
- bc bones are calcified anotehr large effect
- 7.8 hurts sthem particiulaly1/33 of co2 pump out hgas been absorbed
- soem think it sthe volcanoe sbut cars polute way more co2

chapter 7
- 79
- corals are calcifiers also
- 82
- corals buiild cityies and then suppport organisms
- predicted to go extict
- results were sostartling in the beging that they want to drop them'
- corals grow as high asa water level
- grow from 30 degrees to 30 degrees
- faield artificial ocean experiminet allowed for ph to get very low and stay
- direct relationship betwween calcium saturaion and coral groth
- as the satuation decreaes the g=coral growth and diverity goes away
- if the corals die so do occupentsoverfishing
- ag. runofff
- deforstation
- when get sto hot coral sympiotic relatoionship fatrming breaks down becme white
- stop grwoing and die off
- they observe a lunar cycle
- start mating in mass
- low ph will affect how the corals are able to spawn
- chapter 8
- most biodiverse nearthe eqator
- salient: most noticable
- any new species bieng found in artic
- plots are ceperate by tembeture
- the forrest is in motion
- differebnt trees better suited for the climate change
- things are moving away from equator bc too hot
- developed ways to deal with the heat
- almost al organisms have adjusted to seasonal changes
- world has been in a cooling phase
- ice ages were caused by gravatiational tugs of planetary masses
- darwin sugested migrations\
- warming is happening 10 times faster
- species area relationship is clodseset biology equivilent to periiodic table
- "
- self-evident. The larger the area you sample, the greater the number of species
- you will encounter.
- "
- Rather, it’s a curve that slopes in a predictable way. Usually, the relationship is expressed by
- the formula S = cA
- z
- , where S is the number of species, A is the size of the area, and c and z
- not immedieate
- cuve
- no dispersal is bleak but not the case
- fast makes it so that population dcreases bc physically less area when moving fast
- both would g=cause extinction of many speciess
- bc birdas are migrating away from equator
- need to adapt to handel heat
