If a population of invasive fish can be described by the logistic equation, what effect would increasing the fish’s food availability have on K? Would K increase or decrease?

Solutions

Expert Solution

Logistics growth model curve obtained when a population is grown in a medium having the nutrients availability constant. The growth model is obtained and sigmoid shape. It has log phase, log or exponential phase and the constant/stationary phase. It is assumed that the nutrient availability is restricted in a medium. So when a population is grown, after the reproduction; it becomes constant due to restricted nutrient availability. That constant phase of the population is called as carrying capacity (refers as K).

The carrying capacity of a population depends on various factors like the natural hazards, nutrient availability, water resources, thermodynamics, competition, etc.

For different types of nutrients quantity and availability the carrying capacity will also be a difference. Double action maybe of larger size in the nutrient rich medium, hence having greater carrying capacity (K increases), and K decreases when amountof nnutrient of a medium decreases.

The population of deer is currently 2,000 individuals. The population can be described by a logistic model with K = 5,000 and r = ½. If 600 deer are hunted this season, will the population of deer go up, or down, or stay at 2,000? Is this harvest rate sustainable? What is the maximum sustainable yield? Explain.

There are 10000 fishes in koorsala and the fish population obeys the logistic model with harvesting. per capita birth rate is 14% per year the people have been catching 400 fish per year for a long time. One year, due to new fishing equipment, the harvesting rate increases to 550 fish per year. Assuming they carry on with this increased harvesting rate, what will be the fish population in the long run? Give your answer correct to the nearest integer.

Assume there is a certain population of fish in a pond whose growth is described by the logistic equation. It is estimated that the carrying capacity for the pond is 1000 fish. Absent constraints, the population would grow by 240% per year. If the starting population is given by p 0 = 600 , then after one breeding season the population of the pond is given by p 1 = After two breeding seasons the population of the pond is...
