Phytoplankton species richness scales consistently from laboratory microcosms to the world's oceans

Abstract: Species-area relationships have been observed for virtually all major groups of macroorganisms that have been studied to date but have not been explored for microscopic phytoplankton algae, which are the dominant producers in many freshwater and marine ecosystems. Our analyses of data from 142 different natural ponds, lakes, and oceans and 239 experimental ecosystems reveal a strong species-area relationship with an exponent that is invariant across ecosystems that span >15 orders of magnitude in spatial exten… Show more

“…Note, however, that recent work has cast doubt on previous demonstrations and the very existence of the SIE (Dengler 2010;Tjørve and Tjørve in press). In phytoplankton communities of marine and freshwater habitats varying by >15 orders of magnitude in spatial extent, no evidence was seen for the SIE (Smith et al 2005).…”

“…3B). Given that ocean frontal boundaries can represent significant biogeographic barriers (5) and that phytoplankton diversity is governed by species-area effects (35), it seems likely that loss of open-ocean habitat during these cooling events drove extinction pulses in non-ice-adapted, Southern Ocean diatoms. Throughout the mid-to late Miocene and early Pliocene, large-magnitude cooling events seem to have been paced by long-period orbital cycles and as a result were transient in nature, and thus the forcing of species evolution and community adjustment by each new climatic regime was short-lived.…”

“…For a given number of species (S T ), an underlying lognormal distribution on islands will have a larger variance than the comparable distribution of abundances on mainlands. A recent global estimate of z reported by Smith et al (25) for phytoplankton spanning 15 orders of magnitude from microcosms to oceans resembles the pattern of small islands and suggests higher disequitability in these assemblages.…”
