to genmome sequences for many archaeans.
Life in Extreme Environments
- A well-annotated collection of links to sites dealing with
life forms in unlikely places, including such
topics as thermophiles, halophiles, archaea, deep ocean vents.

Sites with general resources
- "The Web's premier archaea and extremophile information resource".
Site contains technical information, such as a directory of
publications and gene sequences. Also includes
external links, especially links to
survey articles for a general audience.
- Peer-reviewed journal dealing with archaea.
Surveys, overviews, tutorials

Introduction to the Archaea
- Very informative set of pages about the kingdom of archaea.
Includes information on the fossil record, life history, systematics,
and morphology, as well as some external links.
Eukaryotes in extreme environments
- Information compiled by Dave Roberts on eukaryotic
extremophiles. Different types are described, and there is a
substantial list of references.
Extremophiles: Living on the Edge
- August 22, 2003 special issue of the
Genome News Network. The articles are detailed, but very
interesting and accessible to a general audience.
Gene Regulation in Hyperthermophilic Archaea
- Brief summary of research at Paul Blum Laboratory.
- Portion of course lecture notes, by Bharat Patel. Discusses DNA
replication and transcription in Archaea.

sequencing the genome of Thermoplasma acidophilum.
Deep sea aliens or long lost relatives?

water and subsisting on copper, gold, and zinc.

- Microbes known as extremophiles which live in extreme environments
-- very hot, very cold, highly acidic, alkaline, or saline -- are
are the subject of active research.
Unlike known prokaryotic or eukaryotic life forms, most of these
microbes belong to the "new" domain of archaea.

Microbes Deep Inside the Earth
James K. Fredrickson; Tullis C. Onstott
Scientific American, October 1996, pp. 68-73
- Over 9000 strains of microorganisms, including bacteria and
fungi, have been found in a variety of subsurface environments.
Some such microorganisms must be capable of living in temperatures
as high as 110° C and utilizing unusual chemical reactions as
a source of energy. They may provide clues to how life originally

Another Domain of Life
Oxford University Press, 2000
- The popular literature on archaea is obviously, though
unfortunately, scant. Perhaps the subject seems too esoteric
to most general readers. But Howland manages to make it
fascinating how single-celled creatures that so much resemble
bacteria are actually very different in significant ways.
The short book doesn't stint on technical details, but is
quite accessible to science-minded readers.
