Summary Introduction
To review:
The change of “r” along with the curve length and factors responsible for the changes in “r.” These changes are to be determined on the basis of the
Introduction:
In populations where the competition is high, logistic growth occurs. It is one of the density-dependent factors in the logistic growth affected by birth and death rates such as competition and predation within the population. Logistic growth is observed in populations who surpass their

- 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?arrow_forwardINTERPRET DATA Examine the top and middle graphs in Figure 54-5. Are these examples of exponential or logistic population growth? Where is K in each graph? (You may need to refer to Chapter 53 to answer these questions.) RESULTS AND CONCLUSION: The top and middle graphs show how each species of Paramecium flourishes when grown alone. The bottom graph shows how they grow together, in competition with each other. In a mixed culture, P. aurelia outcompetes P. caudatum, resulting in competitive exclusion. SOURCE: Adapted from G.F. Gause, The Struggle for Existence (Williams and Wilkins, Baltimore, 1934). Figure 54-5 G.F. Gauses classic experiment on interspecific competitionarrow_forwardDepict the dispersion pattern of the populations in the given scenario below. Explain your answer. A sage plant (Philippine medicinal plant) population releases chemicals from their roots that prevent competitors from growing in the area. A population of king penguins aggressively defend small territories within their habitat.arrow_forward
- Use the information and table to answer the following question. An ecologist is studying a population of mosquitos living in a nearby pond. The ecologist estimates the population size twice a day - once at sunrise and once at sunset - for 5 days during the summer when mosquitos are reproducing. Their data is shown. Based on the data, what is the estimated carrying capacity for the population and what factor may have led to a change in data at day three? a. The estimated carrying capacity is approximately 167 thousand. The population may have decreased during day three because of decreased pressure from a limiting factor such as reduction of predators eating the mosquitos. b. The estimated carrying capacity is approximately 188 thousand. The population may have decreased during day three because of decreased pressure from limiting factors, such as more food being available.c. The estimated carrying capacity is approximately 188 thousand. The population may have decreased during day…arrow_forwardWould you classify these species as weak, moderate, or strong competitors? Explain. Think about population density. Compute the population density if necessary.arrow_forwardGive typing answer with explanation and conclusion A conservationist wants to enhance survival of individual Daphnia populations in the metapopulation along the Scandinavian coast. To be successful, which action would this conservationist most likely carry out in these freshwater rock pools? a. Connecting vulnerable pools by making dispersal corridors to the ocean b.Separating the smallest pools from the largest to prevent immigration c.Removing the shortest-lived Daphnia species from all pools d.Separating pools so the Daphnia cannot mix with one another e.Connecting vulnerable pools by making dispersal corridors between themarrow_forward
- Use the information provided: population experiences density-dependent growth K or carrying capacity is 180 r = 0.032 individual/month 1. Calculate how many bugs are added to the population next month when population size is 65? 2. Now keeping the condition of density dependent growth, let's change some numbers: K=270 and r=0.13. If the current population is 125 bugs, how large will the population be in 12 months?arrow_forwardAn ecologist studied how many kangaroo rats could be supported in two different habitats, a high‐quality habitat and a low‐quality habitat. The ecologist estimated the per capita benefit in each habitat as the number of individuals increased.arrow_forwardDescribe how each of the limiting factors in the simulation affected population growth and carrying capacity(migration, predation, food, disease, and pollution). Include a reason why you think the limiting factor affected the population growth in this way.arrow_forward
