Some scientists believe we are in the midst of a new phase of mass extinction, influenced by human behavior, threatening the earth’s biological diversity and contributing to widespread ecological crises. How can the study of non-human species help shape human responses to these potential threats?
As a genetically homogeneous species, elephant seals have a diminished capacity to evolve in response to environmental changes that may occur in the future—the entire population will be affected, to about the same degree, by any adverse changes. Do you think that elephant seals, regardless of their abundance, should be considered potentially endangered for the foreseeable future? Why or why not?
Based on the food web, would you consider wooly mammoth a keystone species? Why or why not?

- EVOLUTION LINK Biologists have wondered how introduced species that would probably have limited genetic variation (due to the founder effect) survive and adapt so successfully that they become invasive. Part of the answer may be that invasive species are the result of multiple introductions instead of a single one. Explain how multiple introductions from a species native area to an introduced area could increase that species invasion success.arrow_forwardHow does protecting the biodiversity of an area increases the survival of a species’ population? Use the principles of threats to biodiversity (e.g. overexploitation, habitat loss, invasive species, etc.), species dominance or evenness, and genetics of the species (e.g. inbreeding, mutations, founder effect bottlenecks, etc.). Use a Philippine endemic species as an example in your answer.arrow_forwardWe (humans) do not have any ethical burden to worry about other species because extinction is a natural process. True or False?arrow_forward
- Some people declare that we shouldn’t worry about endangered species because extinction has always occurred. How would you respond to this view?arrow_forwardSubject (Biology - Ecology) Discuss the relationship of predation in the extinction of some animals.arrow_forwardPrimates are examples of: a. density-dependent species b. density-independent species c. r-selected species d. K-selected speciesarrow_forward
- The elimination of predators by humans a. will cause its prey to experience exponential growth until new predators arrive or evolve. b. will lead to an increase in the carrying capacity of the environment. c. may increase the population size of a prey species if that prey’s population was being regulated by predation from the predator. d. will lead to an Allee effect.arrow_forwardHow do you think your daily habits might contribute directly or indirectly to the extinction of some bird species? What are three things that you think should be done to reduce the rate of extinction of bird species?arrow_forwardIn your region, what species are threatened with extinction? Why are they vulnerable? Suggest steps that could be taken to increase their populations.arrow_forward
- Tests on wild cheetahs have shown that there is low genetic diversity among individuals. Wildlife biologists and conservationists are worried about what this means for the survival of this species. Why is low genetic variability a big problem when it comes to a species survival in a changing habitat?arrow_forwardWhich of these is a true statement?a. Habitat loss is the most frequent cause of extinctions today.b. Exotic species are often introduced into ecosystems by accidental transport.c. Climate change may cause many extinctions but also expands the ranges of other species.d. Overexploitation of fisheries could lead to a complete collapse of the fishing industry.e. All of these statements are true.arrow_forwardIs the species a generalist or a specialist and how does this niche impact the species of the wild. The giant panda, native to China, and the raccoon, native to North America, share a common ancestor. However, their current status in the wild is anything but common.arrow_forward
