However, this being my PowerPoint, there are a few rules.
1. Rule Number ONE: FOLLOW MY HYPERLINKS
2. Rule Number TWO: USE MY BACK BUTTONS
Yeah, so, everything should work.
That’s all.

Endangerment
3 Endangered
Animals
2 Endangered
Plants
Endangered Species: A species that is so small that there is a chance of extinction
5 of the Most Common Reasons for Endangerment
•Species can’t adapt to any other environment
•Example: cutting down trees in rain forest
Habitat Destructio
n•If the whole species
is not genetically diverse it will be wiped out
•Example: Rabies
Disease
•New species take niche of native species
•New species prey on native species
Introduction of New Species
•When animals breed in their own group too much
•Offspring becomes unhealthy
Inbreeding
•When two animals from different sub-species mate
•Unhealthy genes pass on to offspring
Hybridization
What can be done to prevent Endangerment
Stop habitat destruction Plant trees
3 Endangered Animals1.Peregrine Falcon
2.Indiana Bat
3.Northern Flying SquirrelCLICK
CLICK
Reasons of endangerment: DDT and other pesticides make eggs shells thin Habitat is destroyed
Peregrine Falcon
Reasons of endangerment: Females cross highways up to eight times in one
night (so they get ran over…)
Humans enter hibernation places
Indiana Bat
Reasons of endangerment: Loss of habitat Has to compete for places to live and food sources Southern flying squirrel carries a disease that is lethal to northern
flying squirrel
Northern Flying Squirrel
2 Endangered Plants
Virginia Mallow Northeastern Bulrush
Click on the pictures…
Reasons of endangerment: grows in heavily occupied, construction-prone areas multi-flora rose invades habitat
Virginia Mallow
Reasons of endangerment: People are filling/ditching in their habitat (wetland) Water pollution – Northern Bulrush either lives in deep water, few inches of water, or near a pond’s edge.
Northeastern Bulrush
Invasive Species Native, Introduced, and Invasive Species 5 Common ways of Emigration 4 Common ways Invasive Species Negati
vely Affect our Environments 3 Invasive Animals 2 Invasive Plants
Native, Introduced, and Invasive Species
Native•A species that
has lived in a certain area for a long time
Introduced•A species that
has is introduced to an area where it has never lived before
Invasive•Species
introduced into a habitat that ruin the ecosystem or steal a native specie’s niche
5 Common ways invasive species get into our country
Seeds- carried by the wind or
birds
Plants- brought here for
decoration
Some insects get into wood
(crates, shipping palates) and are shipped
across the world…
Kidnapping exotic species
and selling them for money
Insects-their eggs are in
potted plants brought from
other countries
4 Common ways Invasive Species Negatively Affect our Environments
Steal niches of native species
Interbreed with native
species
Bring diseases into
environments
Prey on native species
They…
3 Invasive Animals Zebra Mussel
Brown Marmorated Stink Bug
Snakehead Fish
CLICK
CLICKCLICK
Problems they cause:Clog “water intake structures” –pipes, and screensHeavily colonize buoys, walls, boats, and beachesDecrease the amount of food available for fish by filtering plankton and particles in the water
Zebra Mussel (Dreissena polymorpha)
Comes from: Eastern Europe and Western AsiaNiche in natural environment:Exploit their ability to attach to a “hard substrate”
Niche in introduced environment:Filter feeder
Comes from: China, Japan, Korea and Taiwan, Niche in natural environment: Attacked fruits such as
peaches, figs, and persimmonsNiche in introduced environment: Huge pests, ruining all sorts of crops
Brown Marmorated Stink Bug (Halyomorpha halys)
Problems they cause:
(Oh, where should I even begin!)
They… ruin crops annoy
people are hard to
kill without squishing, which makes a gross smell.
Baby stink bugs…
Comes from: China, Russia, and KoreaNiche in natural habitat: Preys on native speciesNiche in introduced habitat: compete for habitat
Snakehead Fish (Channa argus)
Problems that they cause: They… prey on
native species
will eat anything
2 Invasive Plants
Sycamore maple Porcelain-berry
Click on the pictures…
Comes from: Europe and western AsiaNiche in native environment: Competes with other trees for habitatsNiche in introduced environment: Competes with other trees for habitats
Sycamore Maple (Acer pseudoplatanus)
Problems it causes:
Produces so many little trees that it is hard for native tree species to live
Comes from: China, Korea, Japan, and far east RussiaNiche in native environment: Used for bedding and landscapingNiche in introduced environment: Used for bedding and landscaping
Porcelain-berry (Ampelopsis brevipedunculata)
Problems it causes:
Spreads fast and takes over both forests and open habitats
Steals habitats of native plants
Reintroduced/Extirpated Species Definitions 1 Reintroduced Species
Definitions
•When a species is introduced into an environment it used to be in
Reintroduced Species
•Species that has become extinct in a certain area Extirpated
Species
In Pennsylvania, the last reported elk was shot in 1867The cause of the extinction of the elk in Pennsylvania was unregulated hunting and clearing the elks’ habitat
1 Reintroduced Species:American Elk (Cervus
elaphus)
Between 1913-1926: the Pennsylvania Game Commission released 117 elk into Pennsylvania from South Dakota and Wyoming
