The frog / amphibian crisis
Transcript of The frog / amphibian crisis
the frog/amphibian crisis. These animals are older then most dinosaurs, and are dying by the thousands. Why are frogs and amphibans dying out? Who is helping them? How you can help?!In this presantion I will tell you the answers to these questions why are frogs and amphibians dying out
reason 1: Alien Species
Native amphibian, populations can suffer decline when alien species are introduced into their habitats. there are lots of reasons for this. For instance a native amphibian species may become the food for the alien species, or the alien species may compete for the native species's food.
reason 2: Over-exploitation
Some amphiban species suffer
huge losses of membres due to the pet
trade, and are caputred against the law
reason 3 : Habitat loss and
Destruction has devastating effects on many organisms
and amphibians are no exception. changes to water drainage,
vegetation structure, and habitat composition all impact the ability of amphibians to survive and reproduce. For example, the drainage of wetland areas for agricultural use of the land directly reduces the habitat available for amphibians which require aquatic habitat for breeding. reason 4: global changes
global climate change is a hugh problem for amphibians
because it can alter there wetland habitat ( it may dry out, prey
can die from changes ) and uv b radiation due to oozone thining
is a threat to a numbre of species reason 5 : Infectious Diseases
one of the huge ones are the chydrid fungus and iridoviruses.
chydrid fungus infections started in AUSTRALIA, then moved all most
all they way across the world. reason 6: pestasides
The widespread use of pesticides, herbicides, and other unnatrual chemicals and pollutants has severely impacted many amphibian populations. scientists have found that pesticides reduse the chance of proper breeding , and make deformaties. the story of a Canadien endangerde frog
rocky mountain tailed frog
How call I tell if it is a rocky mountain tailed frog?
•It’s a little frog, just 2.5 to 3 cm long, usually tan or brown, with “grainyish” looking skin.
•The distinctive tail is found only on males. It is, in fact, a organ that is used to fertilize the females’ eggs .
•Tailed frogs’ eyes have vertical pupils, rather than the round ones most other species have.
•The tadpoles can be identified by their very large sucker-like mouth.
how can you help the frogs
Donate to Wildlife Conservation Action
Help fight climate change and help fight the Uv b rays
Love the environment
Dont use pestasides
and finnally Live and let live
if you see a frog dont pick it up that can spread chyrid fungus
and dont kill frogs they are not peststhey help kill mosquedoes
flys and wasps. thank you all for listening this frog lives in bc and there are not many left, but this is frog
is considerd one of the most amazing in the world because it lives for 15- to 20 years ! the giant asian salamander
this huge salamander is about 6 feet as a adult ! that's as big as a 15 year boy ! This salamander is also known as the hellbender, and lives in ponds in USA, China and Japan. It's the world largest amphiban, it's diet is made of fish and crustasions and it live over 50 years ! but this Amphiban is even more amazing in captivetie. it lives up to 75 years ! and can grow to 6 foot 6 ! but with outourhelp it will die out. it is endagered in Japan, China and Usa.. it needs your help.
this a guy from national giographic hold an a adult female chinese giant slamader dont forget to help the newts and salamanders dotinate to mongabay
