 Introduction Resource- Mammals come in a bewildering variety of shapes and sizes and yet all of the 4700 or so species have some characteristics in common. Indeed, it's the existence of these common features that justifies the...

- 1 Overview Resource
- As you work through this unit you will come across boxes, like the one below, which give you advice about the study skills that you will be developing as you progress through the unit. To avoid breaking...

| | 2 How should we think of monotremes?
- 2 How should we think of monotremes? Resource
- This section contains the first of the activities, Activity 1. If possible, you should do each activity as you come to it; the text that follows it assumes you have done so. However, if this is not possible,...

| | 3 Reproduction in marsupials
- 3 Reproduction in marsupials Resource
- The study of mammals requires you to deal with measurements, which we call numerical ‘data’, and you will get practice with compiling and analysing data if you work through all the units in this series....

| | 4 Milk production (lactation)
- 4 Milk production (lactation) Resource
- In this section, you are presented with a fairly complex diagram, Figure 1. The first thing to do when you come to any diagram is to read the caption (i.e. the title), which explains what it shows. Then...

| | 5 Metabolism and body temperature
- 5.1 Warm-blooded vs cold-blooded Resource
- This section is concerned with another key mammalian characteristic. LoM highlights some of the essential terms and ideas – such as the notion of warm-bloodedness – but for more thorough study, some technical...
- 5.2 Metabolism Resource
- Scientific data are often presented in the form of a table, with the data arranged in columns (running vertically) and rows (running horizontally). You will find Table 1 below. As with diagrams, a table...
- 5.3 Heat production Resource
- There are two graphs in this section, Figure 2 and Figure 3. Graphs are often used to display data in a way that makes trends easier to see than in a table. Simple graphs have two axes, one running horizontally...
- 5.4 Coping with heat Resource
- Not only are there the mechanisms to generate extra heat, but there are cooling mechanisms too, of which sweating is just one example.

- 6 Thermoregulation and mammalian fur Resource
- A coat of profuse mammalian body hair is commonly called fur. Fur provides insulation, which is a property that one first thinks of as useful for mammals to help retain body heat. Fur is a unique and fundamental...

| | 7 What's special about placental mammals?
- 7 What's special about placental mammals? Resource
- As a pointer to the later units in this series, it's helpful to end this unit (as LoM and the TV programme do) by stressing the differences between marsupials and the placental mammals – the mammals that...
