8.4 Human Impact on Species Flashcards
species richness and human population growth directly or inversely proportional
directly
what effect does warmer water (due to climate change) have on organisms
it holds less dissolved oxygen so organisms struggle to get oxygen in the their systems
Is ocean warming slowing or facilitating more algea growth
facilitating (ocean)
does warming ocean cause increased or decreased rainfall? why?
increased bc more evaporation = more condensation = more storms
ocean warming effect on coral reefs
breaking them down bc when coralis warm they expel algea (colorful) that helps them grow
what are the main groups of major human mediated causes of biodiversity loss
global and local
local factors of major human mediated causes of biodiversity loss
land use changes
pollution
resource explotation
exotic species
how does land use changes cause biodiversity loss
hoomans make buildings and other stuff in places of the environment which arent rly compatible with the environment so the organisms start to die and stuff
example of land use change and how it causes biodiversity loss
monoculture which causes most nutrients to go to one plant and also this disrupts the equilibrium from all the species that work together in a certain environment
monoculture
when only one plant/organism resides in an area
concerning land use change
if there are more humans…
there will be less room for natural environments and organisms that were previously there
explain waterborne pollutants
how they can exist
where they go
what they do
can be caused by bleaching of mines and then the pollutants can travel to nearby rivers and other bodies of water (Where runoff goes) and reduce reproductivity and survival of organisms
noise pollution
when a place is too loud that it causes other surrounding organisms to need to change calls and stuff to communicate bc of the loudness
light pollution
when light comes into place where it wasn’t before and it disrupts organisms
hormone mimics
compounds that are derived from drugs but mixeroonied up with the water so that they’re a little diff
where do hormone mimics usually end up
water
what do hormone mimics do to organisms
usually mess with how they reproduce
how are organisms effected by light pollutipn
confuses animals (some move away instead of toward)
invasive species species that do not belong to in environment so they wach life or re up awiging
organismsthatkill others bc ts ebcyubenf ;
if a species cannot adapt to the conditions that they are in, what happened to them
they will become endangered or exiticnt
selective pressures
environmental factors that influence an organisms ability to survive and reproduce (fitness!!!)
what is the driving force of natural selection
selective pressures
how have human activities impacted the natural rate of extinction of other organisms
expedited
what are the main groups of protection methods for endangered species
ex-situ conservation and in situ conservation
