Alien is a type of non native plant, invasive takes spot to grow
gave acronym guide
Introduction: natives in the land of humans. They hatch hike to cruise the planet. They also spread disease.
Humans have done bed stuff to the environment
How does nature work? We should not want to take out invasive plants. We have changed our world too much. How does nature really work? Darwin didn’t talk about ecosystems. Nature is constantly changing (by water or fire). Heal from chain saws! Don’t welcome all alien species (curb their spread). That’s for ourselves, not nature.
Is the 21s century used to revitalize nature
we need to reboot our idea of nature and conservation species
on extinct volcano “green mountain”
nothing is native, all by foreign navy
island created by humans
had a cloud forest, essential island
started with sea turtles and birds
island became hub for communication needs (from Brittan) longest air strip in world
island took seeds from all over the region. Spreading of vegetation. Island ha over 350 hundred plants.
ecological fitting (could be key factor)
odd things happen on islands (sap sucking insects)
ants like to be developed in colonies
most colonies clasped in 2014
Rats not human lead to non-pollination
snakes could also cause problems (brown tree snakes) 10ft long in Guam.
Big changes to the environment around Guam.
talk about European sheep (also rabbits)
these rabbits couldn’t fail
transatlantic exchange (traders)
most aveerything around the world came from traders (melting pot landscape)
issues for many islands
fungus came from people moving around (like rats & people)
Colorado beetle in Soviet Union in the 1950’s
jelly fish in the black sea 8000 eggs per day
clogging fishing nets
human activities pave the way for invaders. (p. 40)
talk of ballast water…it might carry 70000 species
temperature of each port temperature
Treaty was signed, but not used in 2014 to clean off ballast water
could increase the problem (killing items that eat bacteria in the tanks).
Though, you don’t need ships for invaders
the ocean is great for aliens to travel (their life cycle) p.46
if seeds don’t float, they might migrate by flight with birds. seed, algy, micros or with the winds (dust storms)
nature is in flux and is alway rearranging itself. Is it a natural process? p.50
The Kudzu vine came to the US. 1870’s [font porch vine]
for live stock
grows 1 foot a day
talk of Tamarisk is a nest from eeisky birds
p. 58 talk of purple loose strife (liked by native bees)
aliens like disturbed places. Like lake Erie thus the Zebra muscle
they ate most of the pollutants.
the clarity of the lake has improved
zebra spreads throughout the midwest
Pg. 69 talk about the countries biodiversity
alien species promote biodiversity
Britain a nation in knotweed (can thrive almost anywhere)
they brought exotics home 2300 alien plants in Britains
knotweed is an invasive species
was it from wild gardeners
victims of cross lovers
invasive like disturbed soil
around towns and transport areas (invasive plants likes)
talk about wild animals (bore farms) talk of pesticides hurting animals
Myths and Demons
why are their so many invasive plants?
Studies show that 7% of rainfall goes to foreign trees. p. 88
South Africa is a big on invasive trees
sometimes the cure is worse than the disease
talk of rain deer and duck issues
more talk about rodents not vegetation
led to soil erosion
birds, rabbits, cats, mice, etc. plus muskrats
align species comes alone
Use bio controller-like a toad to eat beetles (king toads)
talk of invasive animals (like panthers in Florida?)
talk of bring back ducks!
Chapter 7 Myths of aliens
cold war was a fear of invasive plants
foreign species are up to no good
remember zebra muscle from Russia
invasive plants are part of Homeland Security
a dandelion grows where there is sunlight
Aligns hurt biodiversity (hurts native plants)
High percent of natives have become extinct (p. 108)
study was for only the us (personal view) bad analysis
20 to 30% of interduce species are pests and cause environmental problems (p. 111)
source is questionable????
studies in South Africa yield a rate of only 10%
stats are wrong about aliens
biodiversity with cannels! it increases
are they a distructive force
is it the bedrock of society?
more talk of alien rats
p. 118 honeybee pollination is worth 20B per year
why isn’t there a second look to invasive plants
The Amazon isn’t all native
land is fertile
Eupean invaders bringing plants and diseases
it;s a living landscape becamee rain forest about 500 years ago
Amazon area is mostly man maid
deliberant planning (rain forest)
dark earth 2500 years ago used for fertilization
Rain forest could be from human disturbance
Is the planet shaped by humans?
more talk of Africa.
danger of alien disease
we want unblemished nature
people a causing destruction
human being destroying the harmony of nature
goes back to the garden of Edon
no such thing as a balance in nature!
is evolution an optimizing force for rodents?
fires are a renewal
nature like humans are stuck in a rut, needs cleaning up (with fire) 1980 in yellowstone
the forest recovered the fire on the land
want to take advantage of current situations (species…in he hot spot)
is it like falling in love…interaction between species
Fire shacks and bakes
ecosystems are generally open.
there are thousands of trees in the Amazon rain forest
ecosystems can change to different situations
change in nature is common
trying for stability will bring on instability
can they co-exit? (natural selection)
birds bring in new plants
do we want to protect species?
the invader trees are good for soil, insects, and animal life
on an island the invaders have helped the recreation of nature (or the forest) from Porto Reco
Billions of acers are coming back RECOVERY!
invasive plants seem to come back after removal
can ecosystems recover from invasive?
when plows are put away, nature will come back
the bad lands
industrialization also plays a roll
critter invading cities because if food and for safety
like coyotes in Detroit or Chicago
People talk that invasive plants hurt natives, but do they? It creates biodiversity.
38 fish species live in Chernobyl nuclear pond, natives like envirroment
more opportunity for wildlife
scientist agree that the disaster has made people move out
wild creatures like abandon buildings
NATURE DOES NOT CARE ABOUT BOUNDARIES
do all species have to be saved, or once gone will it do gone forever!
managed ecosystems don’t need to be put together like Disney World.
Chapter 12 The New World
study shown that by 2050 over thousands of species will be in jeopardy with a degree of change in temperature.
we need to help the climate “keep up“
specious of migration of plants
will extinction start evolution?
will aliens speed up the extinction of native plants. It will lead to space form diversity changes (like hybrid modification).
these hybrids become new species
big push to restoration ecology in the 21st century
The new wild need to be left alone to do its thing!
nature does not move back!
