Pandas have become specifically adapted to bamboo forests because they depend on the bamboo for food. Pandas also have a very slow reproduction rate. Females are only capable of becoming pregnant during a 24-to-72-hour window once per year, and they typically only give birth to one cub in the wild. Based on this information, if a major environmental catastrophe like a volcanic eruption or meteor strike destroyed all bamboo forests within the panda ecosystem, what will most likely happen to the panda species?
The species will become extinct since it cannot adapt to the changes fast enough.
The species will evolve into a new species that is capable of eating new food.
The species will migrate to a different location that has more bamboo to eat.
The species will evolve adaptations to eat another food source that is plentiful.

- Which of the following situations has revealed that mutualistic interactions can evolve from prior parasitic relationships? A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.arrow_forwardPandas have become specifically adapted to bamboo forests because they depend on the bamboo for food. Pandas also have a very slow reproduction rate. Females are only capable of becoming pregnant during a 24-10-72-hour window once per year, and they typically only give birth to one cub in the wild. Based on this information, if a major environmental catastrophe like a volcanic eruption or meteor strike destroyed all bamboo forests within the panda ecosystem, what will most likely happen to the panda species? The species will evolve into a new species that is capable of eating new food. The species will evolve adaptations to eat another food source that is plentiful. The species will migrate to a different location that has more bamboo to eat. The species will become extinct since it cannot adapt to the changes fast enough.arrow_forwardChanging conditions put intense pressure on organisms-some of which become extinct. For example, of the original 62 species of honeycreeper found in Hawaii only 18 remain. Scientists have the technologies that may allow bringing back organisms that have become extinct. This brings up ethical questions about the cost/benefit of resurrecting extinct species and whether it is the right thing to do. Joseph Bennett, a professor of biology at Carleton University in Ontario, wanted to determine the cost of resurrecting and maintaining an extinct species. Since the up-front cost of resurrecting an extinct species is very difficult to determine, the researchers decided instead to look at the cost of reintroducing and protecting a resurrected organism in the wild. To accomplish this, the researchers considered 70 animals from New Zealand and 29 animals from New South Wales that went extinct within the last 1,000 years. From this list, they chose 11 New Zealand species and five NSW species that…arrow_forward
- Allan 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_forwardMongooses are not native to Hawaii. They were intentionally introduced on all of the islands in 1883 by sugarcane farmers to control rat populations on sugar plantations. They have since greatly increased their population on some islands, while no populations of mongooses are found on the islands of Lana’i and Kaua’i. Which of the following correctly identifies a challenge mongooses would face if they were introduced onto these two islands? A - There is a lack of rats and other food sources on these islands. B - These two islands have no forest reserves compared to the other islands. C - These islands contain no natural predators for mongooses so they would overpopulate. D - These two islands contain native species of birds and reptiles that would compete with the mongooses.arrow_forwardWhich of the following is an example of the founder effect? a.)

A) Immigrants increase the genetic diversity of pools, slightly increasing r. B) Years of drought decrease the average size of all pools.

Landings of blue crab plummeted in 2002 and 2003, as five years of drought and greatly reduced freshwater flow from underground aquifers led to increased salinity in coastal estuaries. These habitats between open ocean and fresh water are “nurseries” for many marine animals. Speculate about possible causes for the decline in shrimp and blue crab populations.arrow_forward
- In this task, you will assume the role of a wildlife biologist that must decide if reintroduction of cougars into the Eastern US is a feasible mitigation strategy for addressing white-tailed deer overpopulation. You will use scientific information from a variety of sources and what you learn in each learning cycle to support or challenge the reintroduction of cougars to the Eastern United States. Your position on the issue should be based on evidence related to the following factors: impact that the deer population is having on ecosystems • social and economic costs of the overpopulation of deer on various stakeholders • the habitat requirements of cougars, the availability of natural resources and carrying capacity of areas where they would be introduced • potential cougar impact on biodiversity, including on populations of coyote and white-tailed deer potential social and economic costs or benefits to stakeholders in areas where cougars are introducedarrow_forwardVery few species on Earth are completely r-selected or K-selected. Many species in their natural habitats demonstrate a life strategy that ranges along a continuum between r- and K-selected strategies. Use this information to answer the 3 sub-parts. a) Sea otters are marine mammals that live in northern Pacific coasts. Typical female sea otters reach sexual maturity around 3 or 4 years of age, and they reproduce once a year, producing a single pup.Only female sea otters are tasked with raising the offspring. Mothers constantly take care of their pups until they are 8 months old, but only 25% of the pups survive past the first year. Sea otter fur was highly sought after between the 18th century and the early 20th century. Through conservation efforts, the number of sea otters increased. The current world population is estimated to be between 1 000 and 2 000 individuals, and they are considered to be endangered. Their main food source is sea urchins, molluscs, and crustaceans.
