The eastern screech owl (Megascops asio) roosts in tree cavities. As long as there are enough tree cavities available for all the owls in the population, the number of tree cavities has no effect on per capita birth or death rates. If there are more owls than the number of tree cavities, the per capita death rate increases with increased population size (because of increased rates of predation or death by exposure). How does this scenario differ from the traditional idea of density-dependent population regulation, as described by Nicholson (1956) or Turchin (1995)? Does it make more or less sense, and why?

Asian carp are an invasive species of fish. When the Asian carp invade a river or lake, they overtake the food and space from the native fish. What type of density-dependent factor would this be considered? physiological change predation competition disease and parasites
nonmigratory wildebeest populations are limited, mainly by factors that are a.) density independent, top down b.) density independent, bottom up. c.) density dependent, top down d.) density dependent, bottom up
A biologist determines the growth rate of a population of 198 frogs in a marsh near Beaverhill Lake, Alberta, to evaluate the quality of the environment. The researcher finds that, in one year, 34 were born, 86 died, 12 migrated into the marsh, and there was no emigration. a. frogs are considered an indicator species for the quality of the environment. Determine whether the growth rate of this population in one year is a cause for concern. if so, what might the concerns be?
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?
One concept of conservation biology is known as minimum viablepopulation. Some species’ populations are so fragmented andsmall that they may have very little genetic variability left. Withminimal genetic variation in the population, there is little likelihoodthat a population can adapt to an environmental threat, such as anew disease. Florida panthers are at or below the minimum viablepopulation level (estimated population less than 80). 1)Do you think that it is practical to use limited resources toconserve a population like the Florida panther? 2)Why?
Eastern loggerhead shrike is a critically endangered species of bird in Canada. Its population has been declining since the 1960s, and it has been speculated that habitat loss, pesticide usage combined, and climate change have affected the shrike population size. In 2004, there were approximately 70 loggerhead shrikes breeding in Canada. Over the next five years, 111 new shrikes were born, 57 died, and 15 left the area. Calculate the change in the population of eastern loggerhead shrike between 2004 and 2009. Express your answer rounded to the nearest whole number. Answer
In populations of unitary organisms, growth rates and rates of development are generally influenced by intraspecific competition. This essentially leads to density-dependent effects on the composition of a population. 1) Explain/discuss figure b (limpets) 2) Explain/discuss figure a (reindeers)
