attribute NC_GLOBAL acquisition_description String Natural seawater was enriched for photoautotrophs and split into multiple\ntemperatures for two weeks. After the enrichment period, Synechococcus was\nisolated from each temperature. Each isolate's thermal niche was measured\nthrough a series of lab experiments and sequenced.\n \nMethods:\\u00a0Thermal niches were calculated by measuring each strain\\u2019s\nthermal performance curve. This was done by acclimating aliquots of each\nculture for two weeks to a broad range of temperatures between 9\\u00b0 and\n33\\u00b0. Temperatures >33\\u00b0 were added as needed for strains able to grow\nat these levels.\\u00a0 This temperature range was chosen because it exceeds\nthe current summer high and low temperatures in Narragansett Bay, and\nencompasses the projected warmer temperatures expected in coming decades.\nStrains were grown at each temperature in triplicate 8 ml borosilicate vials\ncontaining 5ml of F/2 medium. Biomass was recorded every two days using in\nvivo chlorophyll a fluorescence measured on a Turner AU-10 fluorometer (Turner\nDesigns Inc., Sunnyvale, CA, USA), and growth rates and Eppley-Norberg thermal\nperformance curves (Norberg 2004) were calculated in R (Team 2019) using the\npackage growthTools (DOI:10.5281/zenodo.3634918). Rare cultures containing\ncontaminants (verified using fluorescence microscopy) were excluded from the\ndataset. In two strains for low temperature treatments, LA20 and LA27, after\ntwo weeks of acclimation no Synechococcus cells were observed in the culture,\nso the growth rate was set to zero for these cultures. The results of these\nthermal performance curves are hereafter referred to as a strain\\u2019s\nphenotype.

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.
