Mammals I
Vertebrates 5
When we talk about animals in everyday conversation, we mostly talk about mammals. Mammals live in water, on land and in the air. Countless species of the most diverse sizes and appearances populate our earth. A clear classification is not always possible because of their adaptation to their different habitats. DVD 1: Mammals 1 The first DVD begins with describing the characteristics of mammals, their reproduction and development as well as the regulation of their body temperature. The film illustrates features they have in common, but also looks into the huge differences within the class of mammals. DVD 2: Mammals 2 The second DVD first focuses on the different ways of searching for food and digesting it. Then differences in the brain and sense organs are outlined. The last part looks into the homology of mammals whose basic body structure is unvarying despite their adaptation to the most diverse habitats.

Blogging
The weblog or blog, for short, as a medium is not much older than this century. Blogs came into being in the World Wide Web as ’messages from below’, as web pages from web creators who wanted to share their view of the world with the world. They are short notes, long texts, pictures, videos, which are posted loosely and at random intervals to the world for an undefined public.
