Summary Introduction
Introduction: Experiments are designed to test the hypothesis. The data obtained from the experiments are often represented in the form of graph for easy comparison and analysis. Experiments and data analysis are a part of scientific methods to test a good hypothesis. A hypothesis is a possible prediction of phenomena, based on observations.

- You want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don't feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page.

You do this new experiment at a new location (Bonaire), but use basically the same experimental approach and BACI design as Tuttle. a) You do not separate resident and transient clients (as Tuttle did), and below is a graph of your results showing the effect of the treatment on the total density of client fish in the community. Please explain your result. Imagine that you are planning to publish your experiment and that your answer to this question will be part of the “Results” section of your paper. Please do not worry about hypothetical statistical tests; just assume that the obvious patterns displayed in the graph can be interpreted at face value.arrow_forward
- According to the video, what was the effect of artificially-modified ant density in acacias on the elephant feeding behavior? (Choose one.) a. As the number of ants swarming increased per minute on acacia branches, so did the number of branches fed on by elephants. b. As the number of ants swarming increased per minute on acacia branches, the number of branches fed on by elephants decreased. c. As the density of ants per A. depranolobium increased, the number of trees fed on by elephants decreased. d.

- The following are reasons why randomized control trials (RCTs) are not used to investigate all research questions, except: a. RCTs can be expensive, which can make it difficult if funding is limited b. RCTs can be time-consuming, and it may take months and sometimes years to obtain final results c. For certain research questions and/or certain types of exposure variables, it may not be ethical to conduct an RCT d. RCTs are less valid than observational analytical study designsarrow_forwardWhich of the following is correct concerning the total number of ticks collected at each life stage for each species? a:The highest number of adults were of D. variabilis and the highest number of larvae collected were of D. occidentalis. b:The highest number of adults collected were of D. variabilis, and the highest number of larvae collected were of H. leporispalustris. c:The highest number of adults collected were of D. occidentalis, and the highest number of larvae collected were of I. pacificus. d:The highest number of adults collected were of D. variabilis, and the highest number of larvae collected were of I. pacificus. article link: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0201665 I don't know what else should be included in my question, everything is in the article link that i attachedarrow_forwardIn the Introduction, the authors set the stage for their experiment. What ecological issues were facing Yellowstone National Park when wolves were no longer there, and how were the researchers going to test the questions they wanted to ask? In 4 – 6 sentences, summarize the Methods section of this paper. One of the questions the researchers asked when they began their experiment was “With wolves now back on the Yellowstone landscape for 15 years, how has the reintroduction of wolves affected the recruitment of the woody browse species?” Use data from the Ripple and Beschta paper to support your answer. In any scientific paper, the Discussion is often the most hard-hitting, and where researchers elaborate and explain their results in the context of their experiment and the real world. Explain why when researchers tried culling some of the elk herd it did not have trophic effects, while reintroducing wolves did have trophic effects. Describe the multiple impacts of wolf…arrow_forward
- Colton is having an ant problem at his house and heard that adding more cinnamon throughout his home may repel and reduce the number of ants that enter. He wants to design an experiment to determine the relationship between cinnamon and ants. What is the best testable research question for Colton's experiment? A. How does the number of ants entering a home change throughout the day? B. What spices affect ants? C. Do ants like cinnamon? D. How does the amount of cinnamon in a home affect the number of ants entering? What's the independent variable/Dependent variable/ controlled variable?arrow_forwardRefer to figure 56.22. Are there alternative hypotheses that might explain the increase followed by the decrease in ant colony numbers subsequent to rodent removal in the experiment described in figure 56.22? If so, how would you test the mechanism hypothesized in the figure?arrow_forwardThe pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes?* nd 2 chool The proportion of DDT-resistant mosquitoes in a population remains constant due to O the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is intróduced to a rainforest. Over the next year, the finches show a death rate of…arrow_forward
