Summary Introduction
To write:
The sort of information regarding piping plover and the threats to its survival, which would help to determine the population goal for the species as well as how to attain the goal.
Introduction:
The piping plover refers to a small shorebird, which thrives in the beaches of North America considered its natural habitat. The plover population in the Great Lakes is endangered and comprises just 30 pairs of breeding. A more individualized approach is needed to maintain the habitats of at presently endangered species.

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
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?
In 2010, 150 coyotes (Canis latrans) were counted in Pierce County, WA. And the growth rate is 14 coyortes per year. Following a survey of the community, the social carrying capacity of coyotes was around 500 individuals. How long will it take for the coyote population to reach this human tolerance goal? Biologists have estimated the biological carrying capacity for coyotes in the county to be 1000 individuals. How long will it be before the population reaches carrying capacity using exponential growth? Would it take more or less time for the population to reach carrying capacity if using logistic growth equation and assumptions?

- The northern hairy-nosed wombat has experienced historical population declines, though population have stabilized recently due to conservation efforts. While studying them researchers noticed the following fluctuations in (effective) population size: Year 1: 100 individuals Year 2: 90 individuals Year 3: 50 individuals Year 4: 75 individuals Year 5: 90 individuals Year 6: 95 individuals A. Given this information what is the long-term effective population size of this particular population over the six years? B. Assume that at the start of the study the researchers determined heterozygosity for this population to be 0.63 at microsatellite loci. What would you expect the heterozygosity to be at the end of the six years? (Answer part B)arrow_forwardIn this task, you will assume the role of a wildlife biologist that must decide if reintroduction of cougars into the Eastern US is a feasible mitigation strategy for addressing white-tailed deer overpopulation. You will use scientific information from a variety of sources and what you learn in each learning cycle to support or challenge the reintroduction of cougars to the Eastern United States. Your position on the issue should be based on evidence related to the following factors: impact that the deer population is having on ecosystems • social and economic costs of the overpopulation of deer on various stakeholders • the habitat requirements of cougars, the availability of natural resources and carrying capacity of areas where they would be introduced • potential cougar impact on biodiversity, including on populations of coyote and white-tailed deer potential social and economic costs or benefits to stakeholders in areas where cougars are introducedarrow_forwardThere is a non-harmful species of fly that has a body coloration pattern that is similar to bees and wasps, the latter two of which have a stinger for self defence, while the fly has no stinger. For the fly's colour patterns to help it trick potential predators and therefore avoid being eaten by predators, how common should the fly be in nature relative to the bees and wasps in an area where all these species overlap? Question 1 options: 50% of the total abundance of these groups Rare The abundance of bees and wasps doesn't matter Very commonarrow_forward

Sylvan Lake is a beautiful recreational lake located in central Alberta. It has a total area of 43 km2. If the population of zebra mussels is estimated to be 128 mussels/200 km2, calculate the size of the zebra mussel population in Sylvan Lake. Express your answer as a value rounded to one decimal place. Answerarrow_forwardWould you classify these species as weak, moderate, or strong competitors? Explain. Think about population density.

- You are watching a documentary on television about grizzly bears in North America. The narrator is speaking over a clip of two cubs and their mother walking along a riverbank in a heavily wooded forest. She says that grizzly bear populations are rising for the first time in several decades even though deforestation is still a growing problem in North America. Which of the following could be a possible factor for the increase in the grizzly population? Loss of habitat Reduction of resources Increased industrialization Higher birth rate over death ratearrow_forwardA population of 1,492 finches is introduced to a rainforest. Over the next year, the finches show a death rate of 0.395 while the population drops to 1,134. What's the birth rate for this population? Is this proving to be a suitable habitat? (Two answers) a) Yes, this is a suitable habitat. The birth rate is higher than the death rate. b) No, this is not a suitable habitat. The birth rate is much lower than the death rate. c) 589 d) -358 e) 0.155 f) 0.845arrow_forwardThe Spotted Lanternfly (Lycorma delicatula) is endemic to China and was first identified in the United States in 2014 in Pennsylvania. It was found in New York in 2020. According to the New York State Department of Environmental Conservation (DEC) it poses a significant threat to our agricultural industry, negatively impacts outdoor recreation, and may impact forest health. Draw a graph of how you expect this population to grow in New York State given that there are few predators and ample fruit trees and other host trees (see more information on the USDA page). On your graph annotate and justify your predictions about population growth changes.arrow_forward
- 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.arrow_forwardFor each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. Andean condors reproduce slowly. Females lay one or two eggs every other year. The offspring that hatch are well-protected and cared for, and many reach sexual maturity at five to six years. Although their numbers are being threatened by human impacts, they are naturally long-lived, surviving for seventy to seventy-five years.arrow_forwardThe moose population in Jasper is currently on the decline in Jasper National Park. Some of the reasons for the population decline are liver fluke parasitic disease, return of the wolves in the area, and increased traffic in the highways.
