Chapter 18, Problem 2AC
The pressures created by human population growth and economic expansion place storehouses of biological diversity such as the Tropics in peril. The seriousness of the situation is clear when we consider that probably only 1 out of every 20 tropical species is known to science. What arguments can you make for preserving biological diversity in poor and developing countries, such as those in many areas of the Tropics? Does such preservation require that these countries sacrifice economic development? Suggest some solutions to the conflict between the growing demand for

What are some potential solutions to decrease the threat/endangerment of sea turtles? What can humans do? What are some solutions that scientist or convervationist tried to do to help sea turtles? What is one hypothesis on further environmental, ecological, biodiversity or other biological problems that this solution might intentionally or unintentionally create?
Create a two-part figure showing the effects of forest fragmentation on the community of small mammals relevant to Lyme disease in eastern forests. Figure A should depict the interaction network of a large forestpatch with higher species diversity. Figure B should illustrate how the interaction network and transmission of Borrelia burgdorferi are different in a small forest fragment with low species diversity than they are in largeforest patches with greater diverisity. Eastern forests are diverse communities in which many species interact with one another. Your figure will be asimplified interaction network showing some of the most important species related to the ecology of Lyme disease. Remember that your goal is to illustrate how increasing fragmentation affects forest mammal communities in a way that increases Lyme disease risk.• Choose from the following species for your figure: black-legged tick, white-footed mouse, raccoon, eastern chipmunk, gray squirrel, white-tailed deer,…

- Reintroduction of species into their native ecosystem is a controversial topic. Provide at least 3 reasons in favor of this and 3 against the reintroduction of native species.arrow_forwardAllan Pounds and Kevin Anchukaitis both think only one factor - either climate change or an El Nino event - killed the golden toad. However, might they both be right? Could it be that the dry conditions created by the El Nino event were worsened by underlying climate change effects, so that El Nino and climate change together caused the extinction of the golden toad in Monteverde? Yes, the El Nino event in combination with climate change could have led to the extinction of the golden toad. Multiple factors can influence species' extinction. O No, only one factor - either climate change or El Nino - acting alone killed the golden toad. Species are only ever affected by one environmental factor, never by multiple factors.arrow_forwardCA least tern ENDANGERED ANIMAL is CA least tern questionbases on the bird CA least term Reasons for Endangerment Explain the various factors that have led to this species’ current plight. Expand on these points individually, based on your species’ unique story. Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.) Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?arrow_forward
- If sea otters are removed from the kelp forest ecosystem, sea urchins will be able to live and reproduce with no main predator. Whole “herds” of sea urchins have been known to sweep across the ocean floor, gobbling kelp stands at a rate of up to 30 feet per month and leaving barren sea floor in their wake. Once barren, the entire kelp forest ecosystem is destroyed and can no longer support the diversity of life once found there. The EVIDENCE above supports the CLAIM that which animal along the Central California coast is considered a keystone species?arrow_forwardOne of the challenges faced by organisms as the climate changes is the changes observed in phenology. Describe what a change in phenology would be as a result of climate change by giving me an example of it occurring to some organisms (you can make up the organisms in the example). How would a change in phenology result in a population going extinct (possibly because of a trophic mismatch)?arrow_forwardHabitat fragmentation can lead to: a)The disappearance of the matrix due to decreased habitat heterogeneity b) Changes in patch use by animals, with smaller patches leading increased size of home range or movement for many animals c) Variation in microenvironment near the edge of the patch with negative consequences for diversityarrow_forward
- What is happening to the forest of Madagascar and what is the outcome? Why is saving the biodiversity of Madagascar so important? Why does Australia have such an unusual variety of spiders? What are five reasons species are becoming extinct? What does it mean for a species to be extinct? Give an example How do invasive species travel or spread to a different ecosystem? Give an example. List and describe five examples of declining biodiversity five actions that individuals can do to help create and support biodiversity?arrow_forwardNatural processes of species formation and extinction emerge on a timescale measured in millions of years, whereas human-mediated extinctions are measured on a scale of years to decades. How does this discrepancy complicate our attempts to conserve biodiversity?arrow_forwardThere are six species of animals in an area at the end of Thunder Bay. The area is wooded land covering rolling hills with two small rivers. Most of the area is surrounded by farm land where people have sheep and cows. There are three roads in the area, one of which leads to an expanding subdivision. a) Chose the species you believe to be most likely to become endangered and the species you believe to be least likely to become endangered. Compare and contrast these two species to explain your decision b) Which two species do you think would be most likely to exhibit a competitive relationship? c) Explain two density-dependent factors that may affect population P in this area d) Explain two density-independent factors that may affect population P in this areaarrow_forward
- Most "solutions" to the threats to our valued diversity require a compromise between conservation and short-term human needs. Explain this statement.arrow_forwardThe biodiversity of the planet is rapidly being depleted. Scientists' efforts to monitor and protect biodiversity are being aided by a slew of new technologies and the volunteer work of ordinary citizens. To help scientists in their conservation work, new technologies have been developed. For example, Footprint identification technique (FIT) uses photo digitization to identify the footprints of large cats and other mammals, which will allow collection of data about these animals in a noninvasive manner. Other noninvasive data collection techniques include vocalization identification, drones, DNA analysis, and camera-trapping. Apps such as eBird and iNaturalist allow amateurs to record their observations in open-access online databases for further analysis. Smartphones and drones could be useful in collecting data to prevent poaching, although such technologies are in their infancy and still not widely available in developing countries. Remote sensing could be used to monitor changes in…arrow_forwardSeagrass meadows and vulnerable species in Pacific Islands and BahrainSeagrass meadows have profound impacts on sustaining vulnerable species such as dugongs and turtles. The aim of this assignment is to provide you three studies (two article and a chapter) dealing with seagrass in Pacific and Islands and Bahrain and the Arabian Gulf. Question: What are the differences between the populations of dugongs and turtles in both regions? -What are the main ecological goods and services provided by seagrasses in both regions based on the material, no-material and regulating services?arrow_forward
