Why did the mouse population end up extinct?
One of the main objectives of BI308 is to learn to think scientifically about animal behaviour. I talked about the problems that arise when we tell fables or just-so stories about the things that animals do. Some of the tools and approaches behavioural ecologists use would seem to be designed to help us be scientifically rigorous in our conclusions. But are they perfect? Think about optimality modeling. Could it be misused, leading to the kind of unscientific stories we were hoping to avoid or other misconceptions? Explain your reasoning

3. Where did the 13 species of finches on the islands come from?
4. How did the Grants catch the finches?
5. What features did they measure?
6. What happened in 1977 to the island?
7. What type of birds were more likely to survive after this event?
8. After the El Nino event in 1983, which birds were more likely to survive?
9. What keeps different species from mating on the Galapagos islands?
10. The most likely scenario explaining the different finches on the islands is that:
a) different birds migrated to different islands
b) one species evolved into many different species

This organization is a cooperative of several West Indies islands concerned with the loss of biological diversity on their island nations as tourism and development continue to grow. Scientists working on the island of St. Kitts and its sister island Nevis have uncovered what appears to be a previously undiscovered species of rodent. Based on the original description of this animal, it was placed in a genus within the squirrel family. What you have been hired to do is to help save the population on St. Kitts, which is small and threatened by development. The population is so small that individuals are having difficulty finding mates and, in many cases, the reproductive seasons are being delayed by up to one year. When you arrive in the region and begin your observations, you notice that the Nevis population is very healthy…arrow_forwardQuestion:- What is a plausible hypothesis that describes a possible mechanism to explain the differences between the forest and domestic forms in terms of their specific preferences for humans versus non-human animals.

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.
