In light of reactionary temperatures we can divide anaerobic processes, according to optimal temperature for microorganism to
psychrophilic (5-30[degrees]C), mesophilic (3040[degrees]C), thermophilic (45-60[degrees]C) and extremely thermophilic (up 60[degrees]C).

While

Schmidt's (1963) analysis of fecal pellets from 15 Arctic ground squirrels (Spermophilus parryii) documented a 1000 fold increase in
psychrophilic bacteria (microbes exhibiting an optimum temperature of 15[degrees]C and an inability to grow above 20[degrees]C) and a 1000 fold reduction in coliform bacteria, while numbers of enterococci remained rather constant.
These include
psychrophilic organisms, which live in near-freezing water; halophiles, which inhabit high-salt marine environments such as the Dead Sea; and barophilic organisms, which live in high-pressure areas such as at the bottom of the ocean.
