Biological processes, in contrast to abiotic mechanisms, do not make use of the range of possible organic molecules.
Recent ideas on the origin of life suggest that early cellular structures were abiotic iron-sulfur formations at submarine hydrothermal vents in the Hadean ocean, in which basic biochemical and metabolic processes could have developed before the formation of cell membranes [ 39 40 ] . As well as iron and sulfur, hydrothermal areas are often are often characterized by high levels of arsenic [ 41 ] and may even contain arsenic redox active microbial communities [ 42 ] . Given the integral role of phosphate in early (and current) cellular metabolism [ 39 ] , an ability to reduce the levels of arsenate (a phosphate analog) might have been an essential biochemical process.
Microcosm and mesocosm studies are commonly used in ecological studies of aquatic and terrestrial habitats [ 1 2 3 ] . Microcosms and mesocosms are generally subsets of communities and abiotic factors of particular ecosystems, with restricted exchange of matter and energy [ 3 ] . These containers are by definition smaller than the organism's actual habitat, and controversy exists about the relevance of these studies because of the scaling of simulated habitats and the lack of replication and complexity [ 1 3 4 5 ] . There is often an implicit, and untested, assumption that scaling doesn't affect experimental outcomes in microcosm studies [ 3 ] .
However, what is less clear is the regularity and strength of north–south differences in spatial diversity patterns, and especially the latitudinal gradient in diversity, as well as the ways in which abiotic variation between the hemispheres might extend through the genealogical and ecological hierarchies to effect such differences.
Several groups [ 17 18 ] have used existing expressed sequence tag (EST) collections to carry out microarray experiments in initial efforts to identify genes whose expression levels change in response to pathogens and various abiotic stresses.
