Use the key info from the previous slide to make a prediction about the finches In 1977, there was a severe drought on the island, which caused many of the plants to die out. Because the finches eat the seeds of many of these plants, the population of birds had to compete for the seeds that were available. Most seed-eating finches prefer to eat the small, soft seeds (particularly during the drought), leaving only the large, tough Tribulus seeds for the finches not lucky enough to get to the small seeds in time.

Woodpeckers dig nesting cavities in tree trunks; many other birdspecies subsequently use abandoned woodpecker cavities. Inthese forest communities, what term might be used to describewoodpeckers?
Data was collected concerning Galapagos bird beak size over time. There are 13 types of Galapagos finches, and they are also known as Darwin's Finches. These finches share the same habits and characteristics except for one; they all have different beaks. The differences in their beaks might be the most important aspect of their survival because beak size determines the type of seed able to be eaten. Only the birds with the largest of beaks are able to eat the toughest, biggest, and spine covered seeds. Based on the data given, choose the BEST conclusion. A) This data shows that over time the type of food available remained constant. Eliminate B) This data shows that the environment did not change over the course of time. C) This data shows a fluctuation in bird species over time most likely due to food availability. D) This data shows a fluctuation in bird species over time most likely due to the inheritance of acquired characteristics. Not Graded
Peter and Rosemary Grant of Princeton University have studied the ecology and evolution of finches on the Galapagos Islands since the early 1970s. They have shown that finches with large bills (as measured by bill depth; see Figure) can eat both small seeds and large seeds, but finches with small bills can only eat small seeds. In 1977, a severe drought on the island of Daphne Major reduced seed production by plants. After the birds consumed whatever small seeds they found, only large seeds were still available. The resulting food shortage killed a majority of the medium ground finches (Geospizafortis) on Daphne Major; their population plummeted from 751 in 1976 to just 90 in 1978. The Grants research also documented a change in the distributions of bill depths in the birds from 1976 to 1978, as illustrated in the graphs to the right. In light of what you now know about the relationship between bill size and food size for these birds, interpret the change illustrated in the graph. What type of natural selection does this example illustrate? Source: P. R. Grant. 1986. Ecology and Evolution of Darwins Finches. Princeton University Press.
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

After the drought of 1977, researchers hypothesized that on the Galapagos Islands’ Daphne Major, medium ground finches with large, deep beaks survived better than those with smaller beaks because they could more easily crack and eat the tough Tribulus cistoides fruits. A tourist company sets up reliable feeding stations with a variety of bird seeds (different types and sizes) so that tourists can get a better look at the finches. Which of these events is now most likely to occur to finch beaks on this island? Why? * Increased variation in beak size and shape over time No answer No change in beak size and shape over time. Evolution of yet larger, deeper beaks over time, until all birds have relatively large, deep beaks. Evolution of smaller, pointier beaks over time, until all birds have relatively small, pointy beaks

Clausen and colleagues proposed two hypotheses to explainthis variation within a species: (1) There are genetic differencesbetween populations of plants found at different elevations.(2) The species has developmental flexibility and can assumetall or short growth forms, depending on local abiotic factors.If you had seeds from yarrow plants found at low and highelevations, how would you test these hypotheses?
Many species of animals make alarm calls, whichwarn others in their group that a predator isapproaching. Alarm calls also attract the attention of the predator, making it more likely thatthe individual making the call will be eaten. Whymight natural selection favor the evolution ofalarm calls in a species? How might you test thathypothesis?
