Assessing the efficiency of non-parametric estimators of species richness for marine microplankton( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Abstract Non-parametric asymptotic estimators rely on the assumption that rare species are indicative of the degree of undersampling. We evaluate the performance of 11 non-parametric asymptotic species richness estimators and an individual-based rarefaction and extrapolation (R/E) method using marine microplankton data. These species richness estimators were evaluated by sequentially increasing sampling effort. Their bias was diminished as sample (size) completeness increased. Jackknife estimators were more accurate than others such as Chao's estimators. Underestimates were larger than 10% of species when applied to more than 30% of the individuals present in the community. The magnitude of bias varied as a function of community structure. R/E curves sorted samples by species richness but with a significant sampling error associated. We find that the use of these analytical methods lacks validity for the comparison of marine microplankton species richness estimates from sample collections spanning large spatial and temporal scales

The extent to which the spatial distribution of marine planktonic microbes is controlled by local environmental selection or dispersal is poorly understood. Our ability to separate the effects of these two biogeographic controls is limited by the enormous environmental variability both in space and through time. To circumvent this limitation, we analyzed fossil diatom assemblages over the past 1.5 million years from the world oceans and show that these eukaryotic microbes are not limited by dispersal. The lack of dispersal limitation in marine diatoms suggests that the biodiversity at the microbial level fundamentally differs from that of macroscopic animals and plants for which geographic isolation is a common component of speciation

The role of nutricline depth in regulating the ocean carbon cycle( Book )

1 edition published in 2008 in English and held by 1 WorldCat member library worldwide

Carbon uptake by marine phytoplankton, and its export as organic matter to the ocean interior (i.e., the "biological pump"), lowers the partial pressure of carbon dioxide (pCO₂) in the upper ocean and facilitates the diffusive drawdown of atmospheric CO₂. Conversely, precipitation of calcium carbonate by marine planktonic calcifiers such as coccolithophorids increases pCO₂ and promotes its outgassing (i.e., the "alkalinity pump"). Over the past ~100 million years, these two carbon fluxes have been modulated by the relative abundance of diatoms and coccolithophores, resulting in biological feedback on atmospheric CO₂ and Earth's climate; yet, the processes determining the relative distribution of these two phytoplankton taxa remain poorly understood. We analyzed phytoplankton community composition in the Atlantic Ocean and show that the distribution of diatoms and coccolithophorids is correlated with the nutricline depth, a proxy of nutrient supply to the upper mixed layer of the ocean. Using this analysis in conjunction with a coupled atmosphere-ocean intermediate complexity model, we predict a dramatic reduction in the nutrient supply to the euphotic layer in the coming century as a result of increased thermal stratification. Our findings indicate that, by altering phytoplankton community composition, this causal relationship may lead to a decreased efficiency of the biological pump in sequestering atmospheric CO₂, implying a positive feedback in the climate system. These results provide a mechanistic basis for understanding the connection between upper ocean dynamics, the calcium carbonate-to-organic C production ratio and atmospheric pCO₂ variations on time scales ranging from seasonal cycles to geological transitions
