Ecología Biología de Poblaciones: Capacidad de carga, demografía y ciclos por Devin Reese, PhD. Lectura Prueba Enseñe con esto 1. Which research fits best in the discipline of Population Biology? The study of a group of flamingos that live in a Florida coastal bay. The study of the insect diversity in a wetland ecosystem in Alabama. The study of how two species of Texas lizards have evolved differently. The study of how water pollution is altering conditions in an Ohio River. 2. If the Y axis is number of organisms, the X axis is time, and K is carrying capacity, what principle does the red line illustrate? Use this image for questions 2 and 3. Linear growth, as predicted by Verhulst Logistic growth, as predicted by Verhulst Exponential growth, as predicted by Malthus. Interdependent growth, as predicted by Malthus. 3. Populations of animals typically exhibit density dependent growth. true false 4. Which factors are most likely to determine the carrying capacity of a tropical forest for green tree frogs? Frog reproductive success. Abundance of preferred prey. Presence of tree frog predators. Daily fluctuations in weather patterns. 5. This pyramid graph of the population of the Yukon in 2011 shows a rapidly growing population. true false 6. Which scenario indicates density independent decline in growth? As the number of old growth trees with cavities goes down, the population of spotted owls declines. As the temperature of the river increases from climate change, the number of salmon goes down. As the population of squirrels in the city gets larger, the females have smaller litters of babies. As stone walls that lizards use for sun basking are removed, the population of lizards gets smaller. 7. Which best encapsulates the predictions of the Lokta-Volterra equations model? Populations of prey are regulated by populations of predators. Populations of predators are regulated by populations of prey. Populations of both prey and predators are regulated by each other. Populations of prey and predators are not regulated by each other. 8. When did the tipping point occur in Atlantic Cod populations off the coast of Newfoundland? Use this image for questions 9 and 10.Source: CC-BY Lamiot 1850 - 1885 1885 - 1920 1920 - 1955 1955 - 1990 9. What were the signs that the population was headed towards a tipping point? Population size fluctuated dramatically during the late 20th century. Population size wiggled up and down during the early 20th century. Population size barely cleared 200,000 during the late 19th century. Population size change was very slow and gradual during most of the monitoring period Resultados de Prueba
