Module 10 Conservation Biology and Biodiversity Flashcards
It is more expensive to discover compounds made by an organism than to imagine them and then synthesize them in a laboratory.
false
Endemic species are found in only one location.
true
The loss of biodiversity currently being observed is almost entirely a result of human activities.
true
Resistance to disease is a chief benefit to maintaining crop biodiversity.
true
Many plants produce secondary plant compounds, which are toxins used to protect the plant from insects and other animals that eat them.
true
Crop diversity is not a requirement for food security.
false
White-nose syndrome is an economic principle that resources held in common will inevitably be overexploited.
false
Global warming will raise ocean levels due to meltwater from glaciers resulting in island size reduction
true
The gradual melting and subsequent refreezing of glaciers could result in a reduction of ocean salinity and a shortage of fresh water.
true
Habitat restoration has the potential to restore ecosystems to previous biodiversity levels before species become extinct.
true
Captive breeding programs for endangered species are efficient and are often successful when the species are reintroduced to the wild.
false
The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) treaty provides a legal framework for preventing “listed” species from being transported across nations’ borders, thus protecting them from being caught or killed in the first place when the purpose involves international trade.
true
Which of the following is not a type of biodiversity?
habitat
The FDA approved five drugs based on animal toxins to treat diseases such as…
hypertension.
chronic pain.
diabetes.

biodiversity hotspot
There are various initiatives to catalog described species in accessible and more organized ways. What method is primarily facilitating this effort?
internet

pesticides
___________ is a wild-caught animal used as food (typically mammals, birds, and reptiles); usually referring to hunting in the tropics of sub-Saharan Africa, Asia, and the Americas.
bushmeat
___________are species that have been intentionally or unintentionally introduced by humans into an ecosystem in which they did not evolve.

One form of introducing exotic species to an area is _____
human trade and transportation
In the United States, the first national park with land set aside to remain in a wilderness state was _____________in 1890.
yellowstone park
When an at-risk species is listed by the ____________________, the U.S. Fish & Wildlife Service is required by law to develop a management plan to protect the species and bring it back to sustainable numbers.
endangered species act
______________ is a potential positive impact of zoos on conservation efforts.
education
_____________________ is an agreement between the United States and Canada that was signed into law in 1918 in response to declines in North American bird species caused by hunting.
