How to write the essay

Read the description of the themes for the essay carefully. Please answer the questions given and discuss the topic in the detail you find necessary. Do that within the limits of maximum 10 pages of text, with font size 12 Times or Times New Roman (or something like it), and line spacing 1.5. In addition to the maximum 10 pages, add a front page with only the course code (Bio4010), the title of the essay, and room for your candidate number. Please remember to paginate. Your name should not appear on any of the pages.

            The format of the essay is up to you – select the structure that you feel fits the topic and your style of writing. If you feel that figures are useful, that is fine. But all figures or tables have to fit into the main text, and have a purpose. Be careful to refer to figures and tables in the text. The essay can be written in Norwegian or in English.

            As always when you write a scientific text, you have to be careful to support your statements with references to relevant literature. What you do not need to support with references is what we can call common knowledge that is within the ?public domain?. References can be formatted in different ways – select a form that you like but be consistent. When evaluating the essay, we will look for clear thinking, logical arguments, and consistent writing.

            The essay should be an independent piece of work. That means that it is very well to discuss between yourself, but the written text should be in your own style and showing your own way of thinking. Do not ?borrow? from others without an appropriate reference. Passing off a borrowed piece of text as your own is cheating.

            The topics are related to what we have been discussion these last weeks, and the literature used here is clearly helpful. But to write a good essay it is necessary for you to find more information, using the library and different online search options. Be critical when selecting references – the good essays are those that have good supporting references.

Topic for the essay

Select one of these topics (#1 or #2) for your essay.

 

1. On the egg size – egg number trade off.

This is one of the central trade offs in life history theory, and is very intensely studied. However, despite this, a number of questions still remain to be answered. In this essay I want you to:

            Explain why this trade off is important.

            Give empirical examples of the trade off.

            Discuss why it often is difficult to detect this trade off.

 

1. Is there an optimal age at maturity?

Age at maturity is often said to be the most important life history trait. In this essay I want you to answer the main question given in the title, and in that process I would like you to also discuss the following:

            Why is age at maturity so important?

            Why should there be only one optimal age at maturity?

            What factors influences age at maturity?

During your discussion I would like you to give empirical examples (from the literature).
