The modeled organisms included types analogous to the marine cyanobacterium Prochlorococcus. Their emergent global distributions and physiological properties simultaneously correspond to observations. This flexible representation of community structure can be used to explore relations between ecosystems, biogeochemical cycles, and climate change.

(September 2007), pp. 398-407.</i><br /><br />Prochlorococcus is a simple cyanobacterium that is abundant throughout large regions of the oceans, and has become a useful model for studying the nature and regulation of biological diversity across all scales of complexity. Recent work has revealed that environmental factors such as light, nutrients and predation influence diversity in different ways, changing our image of the structure and dynamics of the global Prochlorococcus population. Advances in metagenomics, transcription profiling and global ecosystem modeling promise to deliver an even greater understanding of this system and further demonstrate the power of cross-scale systems biology.

Here, we describe how the abundance of six known ecotypes, which have small subunit ribosomal RNA sequences that differ by less than 3%, changed along local and basin-wide environmental gradients in the Atlantic Ocean. Temperature was significantly correlated with shifts in ecotype abundance, and laboratory experiments confirmed different temperature optima and tolerance ranges for cultured strains. Light, nutrients, and competitor abundances also appeared to play a role in shaping different distributions. 10.1126/science.1118052 Niche Partitioning Among Prochlorococcus Ecotypes Along Ocean-Scale Environmental Gradients Zackary Johnson Erik Zinser Allison Coe Nathan Mcnulty Woodward Sallie Chisholm doi:10.1126/science.1118052 Science, Vol. 311, No. 5768.
