Chapter 55, Problem 15TYK
Summary Introduction
To review:
The regulations the government is bringing about related to fishing in order to reverse the current trend toward smaller adult size of fish. Explain what selection pressures fishing places on the targeted species.
Introduction:
The excessive harvesting of marine species is known as overexploitation. Improvement in technology led to an increase in the harvesting of fish species. The harvesting of larger and older individuals has caused the maturation of these fishes 3 years earlier and reduced their size.

This section starts explaining how scientists use the population survey data that are collected to model how the lionfish population changes over time. These models enable scientists to make predictions about population changes, which is an important element of developing plans for managing the lionfish population
You'll be using the discrete-time logistic model that is described on this page in future parts of the case study, so make sure to carefully read through the explanation of this mathematical model. Even if you don't have a strong math background, this case study walks through the equation step by step.
6)Which of the following are constant terms in the discrete-time logistic model?
choose all that apply
a)Nt
b)ΔN
c)t
d)K
e)Δt
f)rmax,d
g)None of these
Compare the advantages and disadvantages to a species that result from exponential or logistic growth. Why do you think hares have evolved to reproduce as rapidly as possible, while lynx appear to have intrinsic or social growth limits?
The relationship between predator and prey populations has been studied by computer simulation using equations which form part of a mathematical model devised by Lotka and Volterra. The data in Table 6.10 show the results of such a simulation when the prey population begins with 20 individuals and the predator population begins with six individuals.
1.Explain why the peaks in the predator population occur after those in the prey population.
2. This simulation assumes one prey species and one predator species in an imaginary ecosystem and is based on mathematical equations. Why is it likely to be too simplistic to describe accurately what happens in nature?

- This graph shows the relationship between the number of individuals in a minnow school and how often a predator approaches. This graph would support which of the following hypotheses? Predator approaches per minute 1.0- 0.8- 0.6- 0.4- 0.2- 0 5 10 15 20 Minnow school size There is no fitness benefit for a minnow to live in a large group O Individuals living in a small group are more likely to be attacked by a predator O Individuals living in a large group are less likely to be attacked by a predatorarrow_forwardScenario: You are conducting a study on the influence of population density on body mass in leafy seadragons in oceans off the coast of Australia. You are investigating the biological hypothesis that population density influences body length, and the prediction that individual leafy seadragons in higher density populations will have smaller body length. You have randomly sampled 15 leafy seadragon individuals from each of two locations in Australia, one location has a naturally low population density and the other area has a naturally high population density. The descriptive statistics of leafy seadragon body length (in cm) are shown in the table. What value best represents the t-statistic? (only 2 decimal places are given, recall there could be very minor variation due to rounding.) Low population density High population density X̄ 16.3 15.3 s 2.1 1.7 n 15 15arrow_forwardWhich of the following would not be an example of density-deperident factors regulating population size? The number of possible territories for robins is limited; thus when population sizes are high, a lower proportion of individuals can produce offspring. A. O B. In conditions of overcrowding, some desert pupfish living in ponds will emigrate to other ponds if given the opportunity. C.Predation on mosquitofish is high, regardless of population size. D. In conditions of high density, mice are more susceptible to mortality from heat stress. E. In a habitat patch with a high density of muskrats, a disease spreads more rapidly and results in higher mortality.arrow_forward

- Look at figure 1 in the passage. Which of the following relationships is BEST shown by the data? The more massive the penguin, the more food is delivered to the offspring. B. The maximum efficiency in food foraging is reached at about 20 % sea ice concentration. The amount of food delivered is about the same at 12% and 15% sea ice concentration. The greater the sea ice concentration, the greater the efficiency in delivering food. V07:16arrow_forwardThe figure below shows the interaction between predator abundance and prey abundance.

- You are studying the competitive interactions between largemouth bass and lake trout in a several lakes. Some lakes have both largemouth bass and trout, while other lakes don’t have largemouth bass. You examined the gut content of a large sample of bass and trout. In lakes in which both species are found, 100% of the bass diet is composed of small fish while only 15% of the trout’s diet is composed of small fish. The remaining 85% of the trout diet’s is composed of zooplankton. In the lakes without bass, the diet of the lake trout is composed at 85% of small fish and 15% of zooplankton. What can you conclude from these results? Select one: a. Largemouth Bass will eventually completely exclude Lake Trout from the Lake. b. The absence of Largemouth Bass results in a trophic cascade. c. Largemouth Bass have a greater carrying capacity than Lake Trout. d. Without Largemouth Bass, the trout populations grow exponentially. e. The presence of Largemouth Bass prevents the Lake Trout to…arrow_forwardThink about a predator-prey system that perfectly follows Lotka-Volterra dynamics. The search efficiency parameter (a) represents how quickly the predator finds and kills its prey. What would happen if most the predator population had a parasite that made them less effective predators? Infected animals find and kill prey less frequently (that is, the parasite caused the value of the search efficiency parameter to decline). the populations would still cycle; the amplitude of prey and predator would increase Othe populations would no longer cycle; the prey would increase and the predator would go extinct the populations would no longer cycle; the prey would go extinct and the predator would increase the populations would still cycle; the amplitude of prey and predator would decline the predator and prey populations would no longer cycle; the parasite and the predator populations would cycle insteadarrow_forwardHyena carrying capacity in Mkomazi National Park is 500 (in the absence of competitors). Wild Dog carrying capacity in that park is 700 (in the absence of competitors). The addition of 1 wild dog to the park is equivalent to adding 2.5 hyena. The addition of 1 hyena to the park is equivalent to adding 0.4 wild dogs. Which of these species is the better competitor?
