WRITE ABOUT A THEME: INTERACTIONS In Batesianmimicry, a palatable species gains protection by mimickingan unpalatable one. Imagine that individuals of a palatable,brightly colored fly species are blown to three remote islands.The first island has no predators of that species; the second haspredators but no similarly colored, unpalatable species; and thethird has both predators and a similarly colored, unpalatablespecies. In a short essay (100–150 words), predict what mighthappen to the coloration of the palatable species on each islandthrough time if coloration is a genetically controlled trait.Explain your predictions
Adaptation is an important component for species survival. Genes get selected for based on pressures. It is now
known that several species (bacteria, plants, and animals) adaptions potentially reflect a response to human
actions. Which of the following represent examples of how species are adapting to human behaviors? Choose all
that apply.
O Dandelions getting longer in areas that are constantly mowed
O Bacteria exhibiting antibiotic resistance
O The peppered moth expressing dark coloration genes during the industrial revolution
O Cholera bacteria becoming more mild when water sources are cleaner

- Read this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.arrow_forwardMetapopulations: model The figure below indicates overall colonization and extinction patterns based on patch occupancy for a given metapopulation. If the patch occupancy (P) of the metapopulation is 0.5, which of the following statements is most likely true? Overall Colonization Rate cP(1-P) Overall Extinction Rate - eP A. The patch occupancy is at equilibrium (i.e. not changing). 10 0.75 B. The patch occupancy is expected to 0.50 increase. 0.25 C.

Overall Colonization/Extinction Ratesarrow_forwardWhich of the following scenarios best explains how resource partitioning can lead to adaptive radiation? The lack of competition between individuals leads to better survival and reproduction rates. The utilization of different resources requires different adaptations, selecting for different traits. The lack of competition leads to a more balanced ecosystem, resulting in more offspring. There is no connection between adaptive radiation and the resource partitioning in nature.arrow_forward
- CA 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_forwardC5 x P Parchment Exchange - Leader earn.edgenuity.com/player/ ence- SC5181 A G 5 Mark this and return G how would scientists describe th Why is random distribution of species the least common pattern?

Patches that are very close to another occupied patch or that have large areas are most likely to be colonized. D.

- When would it be appropriate to conduct an exclusion experiment?* When studying how one species affects another species in the same community. When studying how a species from one community would affect another species from a different community. When studying survivorship strategies of two or more different species. When obtaining a population count for a species. Sea otters, Enhydra lutris, are predators of sea urchins, Strongylocentrotus franciscanus. Sea urchins, in turn, feed on kelp. A study was conducted to determine the effect that Enhydra lutris has on kelp biodiversity. To do so, three bays that have had sea otter populations for varying amounts of time were assessed. Two different types of kelp were studied: a perennial kelp, Laminaria groenlandia, and other annual kelps. The results are shown in the graph below.

For example, during the 14th century, the bubonic plague killed approximately one- third of the human population. A. Is the bubonic plague an example of a dènsity-dependent or density-independent factor? Explain. B. Two-thirds of the population survived the bubonic plague, even though many of the survivors were most likely bitten by disease-carrying fleas. In terms of evolution, explain how it was possible to be a survivor. C. Discuss two ways that humans have increased the carrying capacity of their population.arrow_forward
- Explain at least one (1) adaption that our species may develop to continue surviving on eartharrow_forwardChoose all incorrect statement. In 2021, 23 species were declared extinct. Most of these have been presumed to be extinct for decades. Eight of the declared extinctions were bird species endemic to the Hawaiian Islands. One species declared extinct was the Molokai creeper (pictured). Main causes of their extinction include loss of suitable habitat, disease, and predation by introduced mongooses and rats. Avian malaria is transmitted between bird species in Hawaii by mosquitoes that were brought to the islands by ships many decades ago. Which of the following statements is NOT accurate? a.Avian malaria is a vector-borne disease; if it infects 90% of the birds regardless of bird population size, it is acting as a density-independent factor. b.Among vertebrates, bird population sizes have declined the most compared to any other vertebrate group. c.Eliminating invasive rats and mongooses from the Hawaiian Islands, like goats were eliminated from the Galapagos, could help prevent further…arrow_forwardThe Red Queen hypothesis is popular in ecology because it explains well the interaction between two chess pieces, which is a metaphor for sexual selection among related species evolutionary arms race between trees and fish, where trees take up nutrients released by dying salmon evolution of spider web shapes in forests compared to those in grasslands effect of parasites on host population sizes and therefore effects on competitor species evolutionary arms race between parasites and hostsarrow_forward
