DNA from the Beginning is an animated tutorial on DNA, genes and heredity. The science behind each concept is explained using animations related to DNA topics, an image gallery, video interviews, problems, biographies, and links related to DNA. There are three sections, Classical Genetics, Molecules of Genetics and Organization of Genetic Material. Key features are the clear explanations of classical experiments and the excellent photographs of researchers and their labs.
The Encyclopedia of Life is a free, online collaborative encyclopedia intended to document all of the 1.9 million living species known to science. It is compiled from existing databases and from contributions by experts and non-experts throughout the world. It aims to build one "infinitely expandable" page for each species, including video, sound, images, graphics, as well as text. In addition, the Encyclopedia will incorporate the Biodiversity Heritage Library, which will contain the digitized print collections from the world's major natural history libraries.
The Biodiversity Heritage Library (BHL) is a consortium of 12 natural history and botanical libraries that cooperate to digitize and make accessible the legacy literature of biodiversity held in their collections and to make that literature available for open access and responsible use as a part of a global biodiversity commons. BHL also serves as the foundational literature component of the Encyclopedia of Life (EOL). BHL content may be freely viewed through the online reader or downloaded in part or as a complete work.
Animal Diversity Web (ADW) is an online database of animal natural history, distribution, classification, and conservation biology at the University of Michigan, incuding:
* Thousands of species accounts about individual animal species. These may include text, pictures of living animals, photographs and movies of specimens, and/or recordings of sounds. Students write the text of these accounts and we cannot guarantee their accuracy.
* Descriptions of levels of organization above the species level, especially phyla, classes, and in some cases, orders and families. Hundreds of hyperlinked pages and images illustrate the traits and general biology of these groups. Professional biologists prepare this part.
