You are examining the impact of fish predators in a Trinidad stream on the life history traits of a newly discovered species, the puppy guppy. Compared with streams containing no predators, you discover that in streams with predators, mature male puppy guppies are smaller, puppy guppy offspring make up a lower percentage of gravid female mass, the average number of offspring produced by females increases, and the average weight of each embryo decreases. Which of the following responses in life history traits is the OPPOSITE of what you would predict based on the responses of Trinidadian guppies to predators? Group of answer choices mature male size number of offspring produced Percent of gravid female mass for which offspring account embryo weight

After observing a finite population of asexually reproducing salamanders, which of the following outcomes is consistent with Müller’s ratchet? a. The population fitness will decline due to the least fit individuals randomly not surviving to produce offspring into the next generation. b. The population fitness will increase due to the most fit individuals randomly not surviving to produce offspring into the next generation. c. The population fitness will decline due to the most fit individuals randomly not surviving to produce offspring into the next generation. d. The population fitness will increase due to the least fit individuals randomly not surviving to produce offspring into the next generation.
Conservation biologists have altered the evolution of salmon populations in captive-breeding programs. Wild female salmon tend to produce fewer large eggs because the large eggs contain more nutrients for the off spring, giving each individual a greater chance to survive. After just a few generations, however, captive-bred females now lay greater numbers of small eggs. Suggest a possible adaptive advantage for many small eggs in the captive-bred environment. What would you predict regarding the reproductive success of captive-bred females released in the wild?
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 Design an experiment to test the hypothesis that this turtle…
Answer the following questions using this information: Bowhead whales can live up to 150 years, reproducing first when they reach 25 years of age, which is when they leave their mother. The survival curve for this whale species is shown below. Indicate which answer is correct about this whale. % alive age in years 150 O They have a type 1 survival curve and show little parental care of offspring. O They have a type 2 survival curve and show strong parental care of offspring. They have a type 1 survival curve and show strong parental care of offspring O They have a type 3 survival curve and little parental care of offspring.
For most species of turtles, embryos that incubate at lower temperatures typically produce males, whereas those that incubate at higher temperatures produce females. Higher temperatures from global climate change could lead to skewed sex ratios among offspring and a reduction in breeding success as males become fewer in number. What behaviors during the egg-laying season might lead to potential behavioral adaptations that could help maintain an even sex ratio? Pond turtles that nest in more shaded areas around their ponds. Sea turtles that nest during the cooler part of egg-laying season. Sea turtles laying eggs in a communal nest with other sea turtles. Pond turtles that have multiple clutches throughout egg-laying season.
Assume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.
Is the following case study an r-strategist or a K-strategist? American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Offspring are left to develop, hatch, and grow on their own, maturing in about three months.
There are two color morphs in boomer foxes (not a real species), red and gray. Both tend to have a single litter of 4 pups, and there is little difference in pup mortality or reproductive success between the two morphs. Red morphs tend to have their litter in their second year, and most die before 5 years old. Gray morphs tend to have their litter in their third year and most live to 10 years old. Given this information which of the following statements below is correct? Group of answer choices Gray morphs and red morphs have same relative fitness Given that the gray morphs live twice as long as the red morphs their fitness is greater Since red morphs reproduce first their fitness is greater than gray morphs Since gray morphs delay reproduction their pups are fatter
Zooplankton (small animals that live suspended in the water) are sometimes isolated in small ponds caused by glaciers, called prairie potholes. Movement of zooplankton between these habitats is very limited. Because of the small size of zooplankton, each pothole can maintain a very large population. There are no known traits that females use to determine male quality, when males are present, nor is there any obvious sign of male-male competition. When assaying the populations for genetic diversity, you find that all have the same alleles and no new alleles have appeared since these habitats were colonized. At this time, no known traits are under selection. If all of these things are true, then are these populations likely to exhibit changes in allele frequency in the immediate future? O Yes, they will exhibit shifts in allele frequency in the next generation or two in random directions No, if these conditions continue the allelic frequencies will not change Yes, they will exhibit…
You are studying the effect that the commonly used agricultural pesticide "Pestkill" that has been found in bodies of water has on the survival rate of eggs of dragonflies. How will you label your X and Y axes? Check all that apply. Pestkill concentration (mg)" as Y axis label, "percentage of eggs hatched in two weeks" as X axis label "Pestkill" as X axis label, "number of eggs" on Y axis "Pestkill" as Y axis label, "number of eggs" on X axis "Pestkill concentration (mg)" as X axis label, "percentage of eggs hatched in two weeks" as Y axis label
High testosterone is often associated with shorter lifespan in mammals. However, you find a new species of mouse in which males live longer than females under field conditions. Which of the possible explanations below would NOT predict this pattern? Male-male competition often injures the participants. Females suffer costs of reproduction caused by the burden of milk production. Males, but not females, provide territorial guarding that improves the survival of their grandchildren. Females enter menopause and stop reproducing at age five, while males can reproduce until death.
As a follow‑up experiment, researchers placed the Daphnia that were exposed to the Notonecta chemical cues into a tank without chemical cues. The Daphnia reproduced asexually, and the offspring developed in the tank without chemical cues. Predict the relative size of the crest height and width of offspring raised in the tank without chemical cues as compared to the parent Daphnia.
