attribute NC_GLOBAL acquisition_description String Chaetoceros simplex cultures, were obtained from population strain CCMP 200\n(National Center for Marine Algae and Microbiota, NCMA).\n \nEvolution experiment:  \n Eight populations were grown at 31 \\u00b0C, and one was maintained as a\ncontrol at 25 \\u00b0C in regular L1 medium (884 \\u03bcm NO3\\u2212).\n \nAt 31 \\u00b0C, four populations remained in regular L1 medium (884 \\u03bcm\nNO3\\u2212), while the other four received nitrogen\\u2010reduced L1 medium (5\n\\u03bcm NO3\\u2212);\n \nPopulations were maintained in 50 mL polycarbonate culture flasks, at 100\n\\u03bcmol quanta m\\u22122 s\\u22121 cool white fluorescent light on a 14/10 h\nday/night cycle. We gently inverted and randomly repositioned flasks daily.\nEvery three days c. 10^6 cells (never < 6 \\u00d7 10^5 cells) from each\npopulation were transferred to fresh media. We monitored populations by\nmeasuring in vivo optical density daily (436 nm wavelength absorbance) using a\nShimadzu UV\\u20102401PC spectrophotometer before and after each transfer\n \nGrowth rate calculations:  \n When more than two biomass observations (optical density or fluorescence,\ndepending on the experiment) within the exponential growth phase were\navailable, we calculated population growth rates (day\\u22121), as the slope of\nthe linear regression of ln(biomass) vs. time (days). Alternatively, when\nbiomass measurements were made every 2\\u20133 days, we calculated growth rate\nas\n \n(lnB2-LnB1)/(t2-t1)\n \nwhere B is biomass and t is time (days) and the number of generations within a\nparticular time range, \\u0394t, as\n \n(u/ln2)^\\u0394t\n \nwhere u is growth rate.\\u00a0\n \nCalculations were made with R, and scripts can be downloaded from:\n[https://github.com/MariaArangurenGassis/PhytoEvolutionPaper2019](\\\\\"https://github.com/MariaArangurenGassis/PhytoEvolutionPaper2019\\\\\").  \n More details in Aranguren-Gassis et al. 2019, Ecology Letters.

attribute NC_GLOBAL project String Phytoplankton Community Responses
attribute NC_GLOBAL projects_0_acronym String Phytoplankton Community Responses
attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nPhotosynthetic marine microbes, phytoplankton, contribute half of global primary production, form the base of most aquatic food webs and are major players in global biogeochemical cycles. Understanding their community composition is important because it affects higher trophic levels, the cycling of energy and elements and is sensitive to global environmental change. This project will investigate how phytoplankton communities respond to two major global change stressors in aquatic systems: warming and changes in nutrient availability. The researchers will work in two marine systems with a long history of environmental monitoring, the temperate Narragansett Bay estuary in Rhode Island and a subtropical North Atlantic site near Bermuda. They will use field sampling and laboratory experiments with multiple species and varieties of phytoplankton to assess the diversity in their responses to different temperatures under high and low nutrient concentrations. If the diversity of responses is high within species, then that species may have a better chance to adapt to rising temperatures and persist in the future. Some species may already be able to grow at high temperatures; consequently, they may become more abundant as the ocean warms. The researchers will incorporate this response information in mathematical models to predict how phytoplankton assemblages would reorganize under future climate scenarios. Graduate students and postdoctoral associates will be trained in diverse scientific approaches and techniques such as shipboard sampling, laboratory experiments, genomic analyses and mathematical modeling. The results of the project will be incorporated into K-12 teaching, including an advanced placement environmental science class for underrepresented minorities in Los Angeles, data exercises for rural schools in Michigan and disseminated to the public through an environmental journalism institute based in Rhode Island.\nPredicting how ecological communities will respond to a changing environment requires knowledge of genetic, phylogenetic and functional diversity within and across species. This project will investigate how the interaction of phylogenetic, genetic and functional diversity in thermal traits within and across a broad range of species determines the responses of marine phytoplankton communities to rising temperature and changing nutrient regimes. High genetic and functional diversity within a species may allow evolutionary adaptation of that species to warming. If the phylogenetic and functional diversity is higher across species, species sorting and ecological community reorganization is likely. Different marine sites may have a different balance of genetic and functional diversity within and across species and, thus, different contribution of evolutionary and ecological responses to changing climate. The research will be conducted at two long-term time series sites in the Atlantic Ocean, the Narragansett Bay Long-Term Plankton Time Series and the Bermuda Atlantic Time Series (BATS) station. The goal is to assess intra- and inter-specific genetic and functional diversity in thermal responses at contrasting nutrient concentrations for a representative range of species in communities at the two sites in different seasons, and use this information to parameterize eco-evolutionary models embedded into biogeochemical ocean models to predict responses of phytoplankton communities to projected rising temperatures under realistic nutrient conditions. Model predictions will be informed by and tested with field data, including the long-term data series available for both sites and in community temperature manipulation experiments. This project will provide novel information on existing intraspecific genetic and functional thermal diversity for many ecologically and biogeochemically important phytoplankton species, estimate generation of new genetic and functional diversity in evolution experiments, and develop and parameterize novel eco-evolutionary models interfaced with ocean biogeochemical models to predict future phytoplankton community structure. The project will also characterize the interaction of two major global change stressors, warming and changing nutrient concentrations, as they affect phytoplankton diversity at functional, genetic, and phylogenetic levels. In addition, the project will develop novel modeling methodology that will be broadly applicable to understanding how other types of complex ecological communities may adapt to a rapidly warming world.
