Biology

Provides basic information about the properties of over 3500 enzymes. Includes selected literature references and links to PubMed.

Covers topics related to the study of all known hormones (in vertebrates, plants and insects). Each entry consists of an outline, an overview description, and a detailed treatment of the topic.

Includes relevant readings, including review articles, cross-references, and crystallographic data.

Comprehensive reference source to the core topics of molecular biology and also includes general background material for those fields to which molecular biology. Length of entries vary from definition to encyclopedic.

Provides access to databases containing citations and 3-D color images of protein sequences. Also provides links to other molecular biology sites.

Describes "structural and evolutionary relationships of all known protein structures." Provides links to a variety of different information sources, including Swiss-3DImage, RasMol Script, Chime view, NCBI Entrez Sequence Entries or Protein Databank Entries.

Includes biochemistry, plant physiology, cytology, ecology, genetics, evolution, bio-geography, earth history, and the earth sciences. There is worldwide coverage of taxonomic groups: one-third of the entries are devoted to taxa, from bacteria and fungi to the main groups of flowering and non-flowering plants.

Describes the over 1200 animals and plants identified by the U. S. Fisheries and Wildlife Service as endangered or threatened before April 2000.

Scholarly treatment of issues relating to "diversity in the natural world." Long entries written by scholars, usually with extensive bibliographies.

Arguably the most complete and authoritative coverage of genetics ever published.

Different types of articles with varying degree of coverage. Focus is on studies based on the human and mouse genomes, but other important model eukaryotes, as well as pathogenic bacteria, are given in-depth coverage.

An excellent resource emphasizing sequence to function data. It contains (metabolic and regulatory) pathway maps, molecular catalogs, genome maps and gene catalogs and can be searched by EC numbers or enzymes, by compound numbers for chemical compounds, and gene accessions for specific genes.

A list of all the resources related to genetics & medicine produced by NCBI.

Current collection of comprehensive articles on topics ranging from mechanobiology of lung epithelial cells to inert gas transport in blood and tissues. Lengthy references are also included, as well as detailed figures, tables, and equations.

Encyclopedic treatment of the language of neuroscience. Good bibliographies.

Attempts to define the terminology of the "many and varied aspects of microbiology." Includes a number of references for further reading, as well as to identify sources. Some helpful illustrations.

An archive of the entire corpus of knowledge on the enteric bacterial cell, comprised of several hundred modules of information and interpretation, including the genome database. Continually expanded, updated, and revised.

Includes approximately 320 articles providing coverage of the entire field of environmental microbiology and all important topics. Extensive cross-referencing, bibliographies, a comprehensive index, and illustrations (photographs, tables, and line drawings).

Medium-length articles by eminent research scientists, with short bibliographies, on topics ranging from beer-making to viral transcription.

In-depth signed articles on viruses and general topics related to virology. Also includes appendices of current virus nomenclature.

A guide for identifying insect orders, families, genera and important species. Opening chapters provide an introduction to the study and practice of entomology, including methods of insect collection.

Species accounts of over 700 bird species that breed in the United States. Includes downloadable images, videos & birdsong recordings.

This comprehensive work covers topics such as communication, learning, sexual selection, navigation, animal cognition, behavioral interactions of humans with companion animals, farm animals, and animals in the wild.

Defines terms describing taxa, animal behavior, cell structure, Earth history, taxonomic principles, zoogeography, and more. Includes brief biographical sketches of scientists who have contributed substantially to the field of zoology.

Describes the over 1200 animals and plants identified by the U. S. Fisheries and Wildlife Service as endangered or threatened before April 2000.
