Interpreting Data A population of snails has recently become established in a new region. The snails are preyed on by birds that break the snails open on rocks, cat the soft bodies, and leave the shells. The snails occur in both striped and unstriped forms. In one area, researchers counted both live snails and broken shells. Their data are summarized here:
| Striped Shells | Unstriped Shells | |
| Number of live snails | 264 | 296 |
| Number of broken snail shells | 486 | 377 |
| Total | 750 | 673 |
Based on these data, which snail form is subject to more predation by birds? Predict how the frequencies of striped and unstriped individuals might charge over time.

You are surveying of the turtle species identifies several breeding populations in different habitats across the island. After a very warm summer of 2020, you observe that the hatchlings from low-elevation nests are mostly males, whereas hatchlings from higher elevations have an equal female-to-male sex ratio. As a bit more background, temperature influences the sex ratio in some turtle species, a phenomenon called temperature-sex determination (TSD). With this knowledge, you hypothesize this new turtle species exhibits TSD, and that eggs incubated at low elevations during the warm year experienced a high enough embryonic temperature to skew the sex ratio. To test this, you collect 20 newly laid eggs in early 2021 & take them back to the lab to conduct an experiment to test your hypothesis that this species exhibits TSD. Assume you know the average nest temperature in the wild, and you have access to multiple incubators

- A small number of lizards are introduced to an island. Their native habitat is a forest and they mostly live in trees. The island has few trees and the lizards spend most of their time on the ground where they are eaten by snakes. Over many generations the island population of lizards develop shorter toes and longer legs which allow them to run faster on bare ground. The lizards withe longest legs/shortest toes are the least likely to be caught be snakes. After several decades lizards are collected from the island and placed in enclosures. Lizards from the original forest habitat are placed in identical enclosures. Each type of lizard mates and has offspring. The offspring resemble their parents and the offspring of island lizards have shorter toes/longer legs than offspring of forest lizards (i.e the differences you see in nature are also found in a lab setting).

In 1848 he recorded an unusual discovery in his journal. “Today I caught an almost totally black form of Biston betularia (peppered moth) near the centre of Manchester.” This is the first recorded sighting of a dark peppered moth. What was rare in 1848 became common over the next fifty years. By 1900, the peppered moth populations in areas around English cities were as much as 98% dark moths. During that time, England was experiencing what is known as the Industrial Revolution. Factories were being built, and they ran by burning coal for fuel. The result was a dark smoke that covered the surrounding countryside. Trees that had been light and covered by lichens now were dark and bare. Q- Using evidence from the text and today’s lesson, explain why the dark peppered moth population increased to 98% by 1900.arrow_forward

The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time.

They are increasing in number, suggesting that they are resistant to environmental degradation. They are resistant to increases in ultraviolet light. They are of considerable economic importance. Their numbers can be manipulated easily with minimal effects on other species. Their eggs do not have hard shells to protect them from environmental contaminants.arrow_forwardImagine we census a population of rabbits (assume females only) that has been occupying a barn for a few decades. On June 30, 2021, we census the population right after the reproductive season. We count 650 individuals and divide them into 4 age classes: 0-‐6 months, 6 months-‐1 year, 1 year to 1-‐and-‐a-‐half-‐years, and 1-‐ and-‐a-‐half to 2 years. 350 are in the first age class, 175 are in the second, 90 are in the third, and 35 are in the fourth. We repeat the census at six months and find that none of the newborns (0-‐6 months age class) from the first census have produced any offspring, and that 15% of them have died. We find that the 2nd age class had 75% survival and produced 500 offspring. We also find that only 10% of the 3rd age class has survived, and produced 180 offspring. All the rabbits in the 4th age died and produced zero offspring. (a) What is the life table for this population? (i.e., x, bx, sx, lx)arrow_forward
