Chapter 52, Problem 5TYU
Summary Introduction
Introduction:
Dispersal is defined as the movement of an organism or species, multiple species away from the population in which they are born to other locations and then they will settle in that location and reproduce there.

- Invasive species often display a wave of advance as they colonize new areas. Mathematical models based on random dispersal and reproduction have demonstrated that the speed with which such waves move is given by the expression 2Dr, where r is the reproductive rate of individuals and D is a parameter quantifying dispersal. Calculate the derivative of the wave speed with respect to the reproductive rate r and explain its meaning.arrow_forwardŠpecies often arrive at an area by catching a ride on other species-including hosts. For example, a strain of cholera common in Nepal was introduced to Haiti in 2010 by infected UN workers who traveled from Nepal to Haiti. With respect to the cholera pathogen, what type of dispersal is this an example of? O Jump dispersal Diffusion OSecular migration None of the abovearrow_forwardFigure 4. This map shows the range of five different bird species in North America based on data collected from 1980 to 1995. For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. If you transplant Bird X east over the mountains and they die, then this species range is likely limited by dispersal.  Question 16 options:  True  Falsearrow_forward
- A species that has a high rate of long-distance dispersal is more likely to colonize new habitat. But that species may also be less likely to adapt to local conditions, because migration will be stronger than local selection pressures for many loci. In light of those considerations, when do you expect that increasing dispersal might result in the evolution of a larger geographic range, and when might it not?arrow_forwardRead this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another."

- Mutualism often involves co-evolution of mutualists. Describe taking the example of animal plant (wasp-fig) relationship.arrow_forwardConsider why there might be natural selection for poisonous plants to warn potential herbivores with bright colors, but why there seems to be no similar selective pressure for poisonous mushrooms to do the same. Which of the following best explains this difference? a) Fungi, like mushrooms, do not rely on photosynthesis and hence do not need to attract or warn herbivores with bright colors. Plants have a symbiotic relationship with herbivores, which is not the case for mushrooms. Mushrooms are typically more toxic than plants, so there is no need for them to develop warning colors. Most of a fungus's body is the mycelium which exists underground, hence consumption of the above-ground mushroom cap represents a comparatively smaller fitness cost than for plants, whose vital photosynthetic structures can be consumed by herbivores.arrow_forwardUse the word bank for the best answer to fill in the blank: Navigational, transportation, nutritional, facultative, obligate, very fun, antagonistic, co-evolution, symbiosis, predatory, beta, alpha. In this mutualistic interaction between theses two organisms, the plant is benefiting from a mutualism and the fly is benefiting from a mutualism. The flower is pollinated by many different insect species making this a mutualism for the plant.arrow_forward
- Deforestation can have many local effects. For example, is the amount of light that is reflected off of a surface. This is of importance because dark surfaces are required to absorb incoming light to maintain the local area's normal temperature. precipitation albedo mesoderm carotenoids reflectionarrow_forwardPopulations of organisms can be found as clumps, randomly dispersed, or uniformly dispersed. Classify each of the following populations by the way it is dispersed in its ecosystem. Dandelions that produce many seeds dispersed through wind energy Tree of heaven that can produce clones of itself via underground roots called suckers that spread out from the parent tree Honey bees that maintain one social hive Red squirrels defending their individual territories from other red squirrels in the ecosystemarrow_forwardWhich statement about the classic competition experiments involving two Paramecium species is FALSE? The experiment involved interspecific competition. The experiment involved exploitation competition. Each species, when grown alone, exhibited logistic growth. When grown together, the species exhibited logistic growth, but each reached a lower carrying capacity than when it was grown alone.arrow_forward
