Consider two bird species that forage for insects that live in shrubs. The shrubs have a clumped, patchy distribution throughout their habitat. The two bird species have the same ability to locate, capture, and consume the insects. However, one species (species A) uses less energy to fly from patch to patch than the other species (species B). According to the marginal value theorem, which bird species should spend more time in each patch, and why?
A population of 1,492 finches is introduced to a rainforest. Over the next year, the
finches show a death rate of 0.395 while the population drops to 1,134. What's
the birth rate for this population? Is this proving to be a suitable habitat? (Two
answers) *
Yes, this is a suitable habitat. The birth rate is higher than the death rate.
No, this is not a suitable habitat. The birth rate is much lower then the death rate.

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?

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_forwardAfter examining two specific organisms on Movebank.org, consider the movement trends of the two organisms and discuss the importance of this type of data.

You survey three tiny ponds to count the number of tadpoles: one pond has 0 tadpoles, one pond has 10 tadpoles, and one pond has 100 tadpoles. The consumer-weighted density estimate used to quantify the potential for intraspecific competition is as follows: Mean number of tadpoles per tadpole Number of tadpoles present in \the pond where tadpole i is located, Total number of tadpolès N=total number of tadpoles Using this equation, the resource-weighted density estimate across these three ponds is O a. 36.67 tadpoles/pond O b. 110 tadpoles/pond O c. 30.33 tadpoles/tadpole O d. 55 tadpoles/tadpole O e. 91.8 tadpoles/tadpolearrow_forwardFor various reasons, some species prefer to live on the edge of a habitat patch while others fare better if they stay near the middle of a patch.

- In 2010, 150 coyotes (Canis latrans) were counted in Pierce County, WA. And the growth rate is 14 coyortes per year. Following a survey of the community, the social carrying capacity of coyotes was around 500 individuals. How long will it take for the coyote population to reach this human tolerance goal? Biologists have estimated the biological carrying capacity for coyotes in the county to be 1000 individuals. How long will it be before the population reaches carrying capacity using exponential growth? Would it take more or less time for the population to reach carrying capacity if using logistic growth equation and assumptions?arrow_forwardThe carrying capacity (K) is the maximum population size that can be supported or sustained by a given environment. Which of the following statements about the carrying capacity is NOT true? Select one: a. We can think of K as some "average" value that a given environment can support. b. Environmental fluctuations cause the carrying capacity to fluctuate over time. c. Once a population reaches its carrying capacity, the size of the population remains constant. d. When a population overshoots K, individuals die due to lack of resources.arrow_forwardThe carrying capacity of the environment with respect to any population is the maximum number of individuals that can be supported.
