Draw a species accumulation curve for the beetles in Area C3, based on the data shown in Table 1. Ensure that you calculate a standard deviation around each average number of species per sample; plot this on this figure. Make sure you label the axes and that you provide a legend
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
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.
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?
When one species is better at obtaining and holding space than another, it is competitively dominant. Based on the diagram which non-mobile (sessile) species is the dominant competitor in the intertidal? Which is second? Rank the six non-mobile species from (1) most to (6) least competitively dominant. Below are the competitive arrows from the slides (recall that sessile consumers are superior competitors over the algal species). gooseneck barnacle mussel acorn barnacle coral weed black pine Primary Producers nori seaweed 1= strongest competitor and 6= weakest competitor common coral weed [ Choose ] nori seaweed [ Choose ] black pine algae [ Choose ] mussels [ Choose ] acorn barnacles [ Choose ] gooseneck barnacles [ Choose ] > > > >
Give correct typing answer with explanation and conclusion True/False: At equilibrium, the smaller of two islands equidistant from the mainland will have a higher rate of extinction and, thus, (i) fewer species, and (ii) a higher rate of species turnover.

Upper Intertidal Zone Lower Intertidal Zone Balonus kalenvides Chthamalus scellatus The diagram above shows the distribution of two species of barnacle in the intertidal region of the Isle of Cumbrae. Scotland. What is the unusual and interesting pattern Connell noticed in the distribution pattern? O The two species were found together in the intertidal zone. O The two species' distributions were mixed in the intertidal zone. The two species' distributions formed horizontal bands in the intertidal zone that did not overlap. O The two species' distributions formed horizontal bands in the intertidal zone with a large area of overlap where the two species were found coexisting together.
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. Edit More
