Parasites
What kind of parasites can encyst a frog's leg?
Trematode parasites. They can cause major deformities and issues related to the frog’s body.
What system of the frog is primarily targeted by pesticides?
The endocrine system.
What are 3 things that can cause deformities in frogs?
Ultraviolet radiation, various parasites, and many chemicals.
What is the job of the endocrine system?
To make and release hormones.
Why do you think our three solutions address completely different facets of frog deformity?
The problem is multifaceted, and it was important to give attention each aspect.
What happens when tadpoles are exposed to large amounts of Trematode parasites?
There will be an increased amount of deformities and a higher risk of death.
Besides causing deformities in frogs, why are man-made chemicals like atrazine also a concern for humans?
These chemicals are also harmful to us, because they are endocrine disruptors. This means they mess with the body's hormones.
Name 3 parts of frogs affected by deformities.
Many places, some are the reproductive system, legs, and arms; deformities can result in a frog having an extra limb or two, or not be able to have babies.
What hormones are involved in deciding whether a frog has female or male characteristics?
more estrogen=female, more androgens=male
What is a potential problem of introducing too many snails to the environment?
It could cause an imbalance in the ecosystem.
In what 2 ways do snails help reduce the Trematode parasites in the environment?
They capture trematode cercariae in their shells and they also host a “soldier” parasite that kills the trematodes.
What changes occur in frogs when strong chemicals and pesticides are introduced into their bodies?
Their metabolic profiles change.
How do humans play a big role in deformities in frogs?
Man-made chemicals have proven to lead to problems with the endocrine system. This can cause various problems, such as a lacking development.
How does atrazine cause feminization?
It increases production of enzyme aromatase, which causes male hormones (androgens) to become estrogen.
