Concept explainers
WRITE ABOUT A THEME: INTERACTIONS In Batesian mimicry, a palatable species gains protection by mimicking an unpalatable one. Imagine that individuals of d palatable, brightly colored fly species are blown to three remote islands. The first island has no predators of that species; the second has predators but no similarly colored, unpalatable species; and the third has both predators and a similarly colored, unpalatable species. In a short essay (100-150 words), predict what might happen to the coloration of the palatable species on each island through time if coloration is a genetically controlled trait. Explain your predictions.

- Imagine that you are a scientist studying species interactions in Kruger National Park, South Africa. Today, you are observing a pride of lions in the southeast quadrant of the park. Two lionesses brought down a large adult wildebeest. The adult females fed for approximately 20 minutes. Their cubs appeared interested in feeding but were largely kept away from the kill by the adult lions. A clan of hyenas drove the lions from the carcasses and fed for approximately 30 minutes. Two male lions drove the hyenas from the carcass, killing a female hyena. The male lions ate most of the kill; vultures fed on remains. • Describe the form of species interaction that was observed between members of lion pride and between lions and hyenas.• Explain how this type of interaction may affect the population densities of the two species.arrow_forwardImagine that you are a scientist studying species interactions in Kruger National Park, South Africa.

- Below is a short research proposal. Review the proposal. Identify the research question, weaknesses, and propose changes as appropriate. Many butterfly species are known to have long migrations, with some species showing spectacular movements of millions of individuals. One of the ancient tropical species is the Monarch butterfly. Thought to have originated in the Mexican and Central American mountains and valleys, it eventually invaded warming northern regions driven by its search for its valuable food source, the milkweed plant. During the falls season, monarchs from Canada and the United States will start their longest journey known as “The Great Monarch Migration” to Mexico. How the Monarch can accomplish the 3000 miles journey is still puzzling. Your friend, a lepidopterist, wants to develop a proposal to understand how genetics influence Monarch’s ability to sense changing environmental signals aiding them to get to their destinations in the fall. She believes that the…arrow_forwardSubject (Biology - Ecology) Discuss the relationship of predation in the extinction of some animals.arrow_forwardQuestion:- Identify at least 4 different cause that are used by migratory animals to find their way during migration.

- Part A) Which of the following distribution patterns serves as the null hypothesis (null model) in ecology experiments? a. clumped b.uniform c.random d.isolated Part B)Monarchs are able to fly across the Gulf of Mexico and disperse to overwinter and then fly back to the US again in spring. How? a. passive dispersal b.active dispersal c.non-dispersal d.none of these Part c: In a nutshell, the primary concern with global climate change is the: A)increased predictability of precipitation and temperature patterns B)increased predictability of carbon dioxide levels C)decreased predictability of precipitation and temperature patterns D)decreased predictability in carbon dioxide levels.arrow_forwardFor various reasons, some species prefer to live on the edge of a habitat patch while others fare better if they stay near the middle of a patch. In areas with a mosaic of grassland and woodland, warbler fledglings are more likely to survive when their parents nest in the core rather than the ecotone, because the ecotone is also habitat for brown-headed cowbirds. What is the name for the behavior of cowbirds that poses a risk to warblers? Give typing answer with explanation and conclusionarrow_forwardPart A) Ecology is defined as the interaction of organisms and their environment. An example(s) of environmental conditions is/are: temperature nutrients sunlight all of these. Part B)DR TJ freaks out because she doesn’t hear any cicadas singing in January. If she understood the biology of these animals she would know that was because adult cicadas do not emerge from underground until summer! Dr TJ should have a better understanding of the importance of ___ in studying ecology. timing spatial distributions none of these Part C)If I read 50 papers on phenotypic plasticity in sea stars and they all showed that these animals exhibit behaviors that allow them to persist under temperature stress, this would be an example of ____ in science. detection measurement repeatabilityarrow_forward
