Which of the following species would conservation biologists using the ecosystem approach NOT be interested in restoring? invasive species indicator species landscape species suite keystone species none of the above -- as they would be interested in restoring all of them
invasive species
From his research on elephants, Steve Blake learned that elephants have a significant role in marinating the biodiversity of their habitats. For one, they help in seed dispersal as they deposit the seeds of fruit that they eat throughout the forest, with a generous helping of fertilizer. Elephants also order the physical structure of the forest by trampling woody vegetation and opening up the habitat in ways that facilitate diverse plant growth and keep the ecosystem healthy. Such an outsize role by one species that impacts its community in such a dramatic fashion suggests that elephants are: keystone species invasive species endangered species indicator species flagship species
keystone species

Which of the following is TRUE about conservation genetics and elephant ivory poaching? Please choose the correct answer from the following choices, and then select the submit answer button. By sequencing DNA from elephants all across Africa it has been possible to map the ivory trade—from the slaughtered elephants in Africa to the curio shops in New York and Beijing. DNA analysis confirms that elephant populations are safe from being killed for their ivory in countries that are regarded as success stories in eradicating poaching. Since elephant populations across Africa are genetically identical it is virtually impossible to use a confiscated tusk to track down poachers and identify regions of high poaching activity. Only the first and second choices are correct. All of the above is true about conservation genetics and elephant ivory poaching

By focusing on how to protect individual species. By concentrating on maintaining or restoring entire ecosystems. By studying the threats that cause species to become endangered. By working to improve our understanding of the natural world and our relationship to it.

What is the difference between the CBD and CITES? The CBD is a US federal law to protect endangered species while CITES is an international treaty to do the same. CITES more broad as it supports conservation and sustainable use of all biological diversity, not just endangered species while CBD is more focused on endangered species and specifically on regulating global trade of endangered species. CBD is less concrete than CITES as it does not outline any specific targets or provide a mechanism to reach its goals, leaving it up to each signatory to determine how best to proceed. As a result it has been less successful than CITES in accomplishing its goals. Only the first and third choices are correct. All of the above

Which of the following statements is TRUE about the Red List? The Red List was established by the Wildlife Conservation Society in an effort to determine, which species could be recovered and which species cannot be saved. The Red List is a list of all flagship species that have been or can be used as the focus of a public awareness campaign to protect biodiversity. The Red List identifies the conservation status of species on a worldwide basis and species are added to the list when they are at risk of becoming endangered, and removed from the list when their status improves. The species on the Red List are the same as those listed under the U.S. Endangered Species Act. All of the statements above are true in regard to the Red List.

The DNA evidence showed that the following was NOT TRUE of African elephant populations and the ivory trade: Please choose the correct answer from the following choices, and then select the submit answer button. Microsatellites accumulate harmless but inheritable DNA changes resulting in genetic differences among populations of African elephants distinct enough to serve as a fingerprint of that population. The ivory making its way to curio shops in New York and Beijing originated from numerous elephant populations from all over the African continent. Microsatellite analysis of confiscated elephant ivory DNA can determine which population the elephants that are poached come from. Incorrect: Countries like Gabon and Tanzania that are regarded as success stories where poaching was thought to be eradicated, are actually poaching hotspots.

Using the tools that conservation genetics provides to map the ivory trade which of the following scenarios is likely regarding ivory trading and was thus supported at a recent CITES meeting? Since conservation genetics established that there are two different elephant species in Africa but only the forest elephant is gravely imperiled by poaching while the savanna elephant is doing fine the decision was made to ease restrictions on the ivory trade of savanna elephants and closely monitor and regulate this trade using DNA analysis. Since DNA analysis is not preemptive in preventing poaching but helps track down poachers after the fact, there was concern that if trade opened on savanna elephant tusks, then the critically endangered forest elephant would suffer even greater decimation, as demand would rise making it even more profitable for black marketers to operate. As a result, at the request of several African nations, CITES instituted a ban on ivory trading. Several African nations had, with CITES permission, auctioned off their stockpiled ivory that DNA fingerprinting confirmed had come from animals culled to maintain herds sizes within park capacity. Since selling this ivory helped elephant conservation efforts by reducing the market for illegally killed animals and by increasing funds for conservation initiatives the decision was made to continue to allow African nations to sell the ivory that came from culled animals. Zambia and Tanzania petitioned CITES for permission to sell their stockpiled ivory (from elephants that died naturally) as the ivory was just sitting there and the countries themselves could really use the money. Furthermore, they insisted that as poaching had been all but eliminated within their borders, there was no risk of losing elephants to poachers. But when the DNA analysis showing that more than 60% of the ivory seized that year did in fact come from Tanzania and Zambia, CITES quashed the petition. The first and third choices were both supported at the recent CITES meeting

Conservation biologist Daniel Janzen has worked for 40 years in the area around Guanacaste National Park in Costa Rica on forest land which had been converted to pastures and agricultural land. His plan involved protecting the area from invasive, non-native grasses and fire; replanting trees; and allowing pioneer species from neighboring forests to return and reestablish. Through this process of secondary succession, the area is now home to an estimated 235,000 species. This approach that benefits the entire community and not just endangered species is referred to as: conservation genetics ecosystem restoration ecosystem remediation landscape conservation conservation biology
