Which of the following best predicts the consequences of introducing small Indian mongoose to an island where they did not previously exist?( Invasive species) (Choice A) A The mongoose population will grow rapidly, disrupting the island's community structure by preying on native animals. (Choice B) B The mongoose population size will likely remain small, and as a result the mongoose population will not be able to outcompete other predator populations for resources. (Choice C) Without any natural diseases, the mongoose population will become established and help increase the species diversity of the island. (Choice D) D Without its typical food sources, the mongoose population will not be able to become established, and the island ecosystem will remain stable. answer explain

Environmental scientists David Pimentel, Rodolfo Zuniga, and Doug Morrison of Cornell University reviewed scientific estimates for the economic and ecological costs imposed by introduced and invasive species in the United States. They found that, as of 2005, approximately 50,000 species had been introduced in the United States and that these accountedfor over $120 billion in economic costs each year. These costs include direct losses and damage, as well as costs required to control the species. (The researchers did not quantify monetary estimates for losses of biodiversity, ecosystem services, and aesthetics, which they said would drive total costs several times higher.) Calculate values missing from the table to determine the number of introduced species of each type of organism and the annual cost that each imposes on our economy. Of the 50,000 species introduced into the UnitedStates, half are plants. Describe two ways in whichnon-native plants might be brought to a new location.How…
Which of the following best predicts the consequences of introducing brown rats ( invasive species) to an island where they did not previously exist? Choose 1 answer: Choose 1 answer: (Choice A) A The rat population size will likely remain small, and as a result the rats will not be able to outcompete other organisms for resources. (Choice B) B Without its typical food sources, the rat population will not be able to become established, and the island ecosystem will remain stable. (Choice C) The rat population will grow rapidly, disrupting the island's community structure by feeding on native plants and animals. (Choice D) D Without any natural predators, the rat population will become established and help increase the species diversity of the island answer explain
The Barton Springs salamander is an endangered species found only inthree adjacent springs in the city of Austin, Texas. There is growingconcern that a chemical spill on a nearby freeway could pollute thespring and wipe out the species. To provide a source of salamanders torepopulate the spring in the event of such a catastrophe, a proposal hasbeen made to establish a captive breeding population of the salamanderin a local zoo. You are asked to provide a plan for the establishment ofthis captive breeding population, with the goal of maintaining as muchof the genetic variation of the species as possible. What factors mightcause loss of genetic variation in the establishment of the captivepopulation? How could loss of such variation be prevented? With theassumption that only a limited number of salamanders can bemaintained in captivity, what procedures should be instituted to ensurethe long-term maintenance of as much variation as possible?

Mongooses 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.

The Atlantic cod population is of primary economic importance to fishingcommunities throughout the maritime provinces in Canada. Unfortunately, thispopulation has underwent an extreme collapse in recent years due to overfishing.Some argue, however, that the collapse of the cod population may actually beattributed to an increase in the population of harp seals, a known predator ofcod. One suggestion to help cod stocks recover is therefore to permit the huntingof harp seals on a large scale. Suggest and explain one potentially negativeconsequence of limiting the harp seal population.
