- The largest population that can be maintained by a particular environment for an indefinite period is known as a (a) semelparous population (b) population undergoing exponential growth (c) metapopulation (d) populations carrying capacity (e) source populationA starting population of 300 individuals grows by 33% every year. Assuming that resources are unlimited, how big will the population be after 5 months (note: months not years)? Question 4 options: 333 338 364 321 Previous PageNext PageWhich of the following populations would be growing? a) Geometric rate (1) = 0.63 b) Exponential growth rate (r) = 0.63 c) Net reproductive rate (R0) = 0.63 d) All of the above populations are growing
- Back at the original beaver population, only 40 beavers remained. This population also has a growth rate of 0.6 and generation time of 2 years. But the place on which this population resides is much smaller and has a carrying capacity of 200. How many beavers do you expect to find in the original population after 6 years?Once an abundant species in Alberta, the caribou population is currently staggering at approximately 6,700 individuals. Little Smoky caribou herd is located in Northern Alberta, and its population is a risk of extirpation. In 1970, there were only 123 caribous in the Little Smoky area with a per capita growth rate of –0.258 between 1970 and 2012. What was the population of Little Smoky caribou herd in 2012? Express your answer rounded to the nearest whole number.several years ago wolves were reintroduced in to a national park in North Carolina. Researchers have monitored the populations over the last several years and the per capita growth rate of the population is.5. If the current population size is 100, what equation would you use to determine how large he population will be in ten yearS? N/t *r N(1+r)^t (N*r)/t please highlight the answer
- The mark-recapture method is used to estimate the population size of mountain yellow-legged frogs in the San Gabriel Mountains of southern California. 100 frogs are captured and marked. A week later, 50 frogs are captured, and 10 of them are marked. The total population size isBased upon r or Ro, is the population growing, declining, or stable? How often do we get a new generation of fish? Justify your answer.A wildlife preserve currently has 30 elephants. If the population grows as expected, the population will double every 30 years. Determine how many it should take number of elephant in preserve to reach 80.
- In an effort to measure the size of a bluegill population in a pond, you set 10 traps for bluegills. You catch and mark 40 with a tag on the tail fin and then release them. A week later you return to the pond and set 10 traps and you catch 40 more, of which 8 have a tag on the tail fin. What is the best estimate of the bluegill population in the pond?A population of bats exhibits logistic growth. The carrying capacity is 600 bats and the maximum per capita Growth rate (rmax) is 0.20. The population size was determined periodically. Determine the population growth rates based on a population size of 50, 100, 200, 350, 480, 500, 525, and 600 bats. Include up to three decimal places in your answers.

Describe the relationship between population size and growth rate. üüA coyote population in Colorado has 40 individuals, the potential reproductive rate per individual per year is 1.5, and the carrying capacity of the area is 50 coyotes. In the same habitat, the bobcat population has 30 individuals, the potential reproductive rate per individual per year is 2, and the carrying capacity of the area is 100 bobcats. The bobcats depress population growth of coyotes through competition by 0.20, while the coyotes depress population growth of bobcats through competition by 1.1. What will the population size be for coyotes next year? *Note that this is the other half of the bobcat question, and you need to round your answer to a whole animal. 40 5 45 16 55
