Michael Madigan, Raven and Johnson's Biology, Sixth Edition


This online enhancement chapter of Raven and Johnson's Biology, a textbook for undergraduate majors, examines the many prokaryotic organisms that inhabit "extreme environments"–habitats in which some chemical or physical variable(s) differ significantly from that found in habitats that support plant and animal life. Topics include using new molecular techniques to discover more about bacteria; life at high temperatures, low temperatures, extreme pH levels and in a brine; and extremophiles in the evolution of life.
