Simons Early Career Investigator in Marine Microbial Ecology and Evolution Awards 2018 Request for Applications

The Simons Foundation is now accepting applications for its Simons Early Career Investigator in Marine Microbial Ecology and Evolution Awards. The deadline for receipt of letters of intent (LOI) is November 6, 2017, 5:00 PM Eastern Standard Time.

Overview

Microbes inhabit and sustain all habitats on Earth. In the oceans, microbes capture solar energy, catalyze biogeochemical transformations of important elements, produce and consume greenhouse gases, and provide the base of the food web.

The purpose of these awards is to help launch the careers of outstanding investigators who will advance our understanding of marine microbial ecology and evolution through experiments, modeling or theory. Projects focusing on the microbiomes of invertebrates or vertebrates or on paleontological records will not be considered this year. Investigators with backgrounds in different fields are encouraged to apply.

Eligibility

Applicants must hold a Ph.D. or equivalent degree. She/he must have carried out research in a tenure-track or equivalent independent position for at least one year and no more than eight years (start date between November 2009 and November 2016) and must currently hold a tenure-track, tenured, or equivalent independent position in a U.S. or Canadian institution. She/he must be the principal investigator (PI) or co-PI currently or within the past year on a research grant from a national governmental agency or major foundation.

About the Awards

Grants will be for $180,000 USD per year, including indirect costs (limited to 20 percent of modified total direct costs), for a period of three years, subject to annual reviews and continuation of research in areas relevant to the purpose of this program. Appropriate expenses include salary support for the investigator and postdoctoral and graduate research assistants, travel, equipment, supplies and other research expenses. Awards will begin April 1, 2018. Awards will be governed by the Simons Foundation policies, which can be found at http://www.simonsfoundation.org/funding/policies-and-forms/.

Andrew Barton is an Assistant Professor at the Scripps Institution of Oceanography and at the section of Ecology, Behavior and Evolution of the University of California, San Diego. His research combines observational and numerical modeling perspectives to understand the fundamental mechanisms that regulate microbial population dynamics, community structure, biogeography and biodiversity in the ocean. Barton investigates how changes in Earth’s climate, including natural variability and long-term changes driven by human activities, have the potential to alter microbial species distributions and community composition through time. He received a B.A. in Science of Earth Systems from Cornell University (2000) and a Ph.D. in Climate Physics and Chemistry from Massachusetts Institute of Technology (2011). He was an NSF International Research Postdoctoral Fellow hosted jointly between Duke University and the University of Liverpool in the United Kingdom, and later was an Associate Research Scholar at the Geophysical Fluid Dynamics Laboratory at Princeton University.
 
Project: Environmental and ecological drivers of marine microbial morphology
 
The diversity of photosynthetic marine microbes can be astonishingly high, with up to hundreds of species coexisting in a single teacup of seawater. The coexisting community exhibits tremendous variation in cell size, shape and coloniality (some species form chains of cells, for example), and this morphological variation may help sustain species diversity by providing multiple avenues for species to survive in the ocean. Far from being ecological curiosities, morphological variations impact ecosystem function by influencing the export of carbon from the ocean surface to greater depths. To date, however, we have limited understanding of what sustains this great morphological variation and its wider significance.
 
The proposed work is an interdisciplinary and multi-methodological research campaign to study the environmental and ecological drivers of the size and shape of phytoplankton cells and colonies. We will use high-resolution underwater images of phytoplankton cells, colonies and zooplankton from the Scripps Plankton Camera (spc.ucsd.edu), in combination with oceanographic and atmospheric observations, to quantify how the size, shape and aspect ratio of phytoplankton cells and colonies vary with environmental and predatory conditions. We will complement the observational program by developing novel trait-based numerical models of the plankton community that resolve varying body size, form and colony size. Our aim is to extend the lessons learned at Scripps Pier to the globe using coupled ocean circulation, biogeochemical and plankton community models, where we can quantify biogeographic patterns of morphology and their biogeochemical impacts. Thus, the goals of the proposed research are to: a) understand how environmental and ecological processes shape phytoplankton and colony morphology and b) map and predict the diversity and biogeography of morphologies over the global ocean and their significance.

She is particularly interested in the molecular basis of microbial micronutritional requirements and what the consequences of those requirements are for global carbon, nitrogen and sulfur cycling. Her group employs a range of quantitative mass spectrometry–based techniques, paired with field and laboratory experiments, to ask these questions.
 
Project: Quantifying the impact of rising temperatures on microbial micronutrient demand
 
Marine primary productivity, conducted largely by phytoplankton, forms the base of marine food webs and is a major factor in determining the relationship between the ocean and atmospheric CO2 concentrations. Temperature, nutrient and light availability are key drivers of phytoplankton growth. Questions regarding how these variables interactively influence photosynthetic microbes remain and are a major source of uncertainty in efforts to predict future changes in marine primary productivity. Along with macronutrients like nitrogen, phosphorus, and silica, phytoplankton also require a suite of micronutrients including iron, zinc, and cobalamin (vitamin B12). In vast regions of the surface ocean, phytoplankton growth is limited by the availability of these micronutrients. Given the extent of this limitation as well as the fact that micronutrient availability is projected to change regionally in the coming decades, understanding the ramifications of simultaneous alterations in micronutrient availability and temperature for phytoplankton growth is imperative. Available evidence suggests that micronutrient demand may decrease in the face of elevated temperatures; however predictions from cellular models are not always reflected in observations and so major uncertainties remain. This research program aims to identify, quantify and contextualize interactions between micronutrient demand and temperature in marine microbes. This research program will use a combination of quantitative field, laboratory and metabolic modeling approaches to (1) enhance our understanding of the role of micronutrients in a changing ocean, (2) offer empirical data for evaluating fundamental questions about the relationships between matter and energy balance in microbial ecology, and (3) provide clarity to global modeling efforts seeking to predict changes to primary productivity in the future ocean.

Project: Quantifying microbial activity in the deep sea using NanoSIMS
 
The deep sea, also known as the dark ocean, is one of the largest habitats for microbial life on the planet: it covers nearly two thirds of the Earth’s surface and harbors approximately 55 percent of all marine microorganisms. Although severely understudied relative to the photic zone, the activity of deep microbial life plays an important role in marine biogeochemical cycling. In particular, recent evidence has shown the importance of chemoautotrophic Thaumarchaea, a phylum of archaea comprising about 20 percent of all marine microbes, in the cycling of nitrous oxide and carbon dioxide, both greenhouse gases. Our knowledge of the diversity and distribution of microorganisms in the deep sea has expanded in recent years with the development of next generation sequencing (i.e., “-omics”) methodologies. However, our understanding of microbial activity in the deep sea, including its phylogenetic and physicochemical controls, is still lacking. Closing this gap in our knowledge will increase our understanding of greenhouse gas cycling in the marine environment, and will better equip us to predict the activity of deep-sea microorganisms in a changing climate. This project will develop and utilize new methods to use nanoscale secondary ion mass spectrometry (NanoSIMS) — a tool to measure the isotopic composition of individual, uncultured cells — to quantify and characterize microbial activity in deep ocean waters. Combined with metagenomic and metatranscriptomic analyses, this work will link geochemical and molecular datasets, and specifically address the role of Thaumarchaea in deep-sea biogeochemical cycling.

Project: The role of marine microbial plasticity in evolution and biogeochemistry
 
Marine microbes are the engines of global biogeochemical cycling in the oceans. They are responsible for approximately half of all photosynthesis on the planet and drive the ‘biological pump,’ which transfers organic carbon from the surface to the deep ocean. Therefore, it is important to determine how marine microbes will adapt and evolve to a changing climate in order to understand and predict how the global carbon cycle may change, and predict pivotal feedback responses that might impact future climate states. This work focuses on developing a mechanistic understanding of how marine microbes respond to environmental fluctuations, and exploring how these individual-scale responses can result in large-scale ecosystem shifts and ecosystem-climate feedback loops. Untangling the complex interactions between climate and biology requires pioneering interdisciplinary approaches. The research will integrate ecological and evolutionary theory, and biological, chemical, and physical observations with innovative numerical ecosystem models, to gain new insight into the relationship between plasticity and evolution in marine microbial ecosystems.

Andrew became an Assistant Professor in the Department of Biological Sciences at the University of Arkansas in 2011.
 
Project: The Genomic Basis of Microbial Adaptation to New and Changing Environments
 
Although evolutionary biology is a historical science, it provides a powerful means of looking forward as well—offering predictions on issues ranging from the spread of human disease to adaptation of species to global climate change. Increased atmospheric carbon and global warming are having profound impacts on the world's oceans. Changing precipitation patterns and melting polar ice caps are freshening large regions of the ocean, resulting in changes in water stratification, convection, and nutrient availability. Although these changes are predicted to have important impacts on the phytoplankton communities in these areas, relatively few data are available to predict how phytoplankton—which produce 40% of the earth's oxygen and form the base of marine food webs—will respond to a rapidly changing ocean. Laboratory experiments have shown that microbial eukaryotes can adapt quickly to environmental change in vitro, but it's not always clear how these results extrapolate to natural systems. This project leverages a natural evolutionary experiment, the colonization of low-salinity habitats in the Baltic Sea by an ancestrally marine diatom, Skeletonema marinoi, to determine the mechanisms and rate of adaptation to environmental stress across ecological and evolutionary timescales. Comparative and population genomic data, together with experimental transcriptomic data, will be combined to determine the tempo and mode of environmental adaptation of S. marinoi populations spanning the North–Baltic Sea salinity cline. Data from a related species, Skeletonema potamos, which has independently adapted to freshwaters, will show whether there is more than one adaptive solution to managing salinity stress, providing general insights into the adaptive potential of phytoplankton to a rapidly changing ocean.

Project: Systems Ecology of Particle-Attached Microbial Communities in the Ocean
 
Bacteria play an essential role in the oceans by digesting particles of organic matter that would otherwise sink to the ocean floor and remove essential nutrients from the marine food web. At the micro-scale, particle degradation is carried out, not by a single species, but by a multi-species collective (i.e. a community) that grows attached to particle surfaces. Within these particle-attached communities there is a multitude of bacteria-bacteria interactions that can control the function and dynamics of the community, ultimately affecting the global ecosystem process. By and large, the nature of these interactions and their impact on community dynamics and ecosystem function remain unknown. This gap in our understanding of microbial ecology ultimately hampers the development of mechanistic models that explain how ecological function emerges from interactions within hyper-diverse microbial collectives.
 
This Simons Early Career Investigator Award will support the development of a systems ecology approach to the study of particle-attached communities in the ocean. Within this research program we will learn the general structure of ecological interaction networks on particles, and the classes of interactions that dominate the particle-attached community. We will learn for instance whether interactions are primarily exploitative, competitive or mutualistic, and how these different types of interactions impact the degradation dynamics. Overall, through this project we will establish the link between micro-scale community ecology to macro-scale ecosystem function in the ocean.

Project: The role of uncultured microbes in the Arctic marine sediment carbon cycle
 
The Arctic is experiencing disproportionately large effects of global climate change and melting glaciers will likely deposit large amounts of organic carbon into Arctic coastal marine zones. Once this organic carbon is deposited on the seafloor, microbes quickly use up all the available oxygen, leaving the rest of the carbon cycle to anaerobic microbes. Little is known about the responses of the sedimentary microbial populations to this increasing organic carbon deposition. If anaerobic microorganisms living in the upper meter of Arctic marine sediments adapt quickly to the increase in organic matter, much of this organic matter will be remineralized back to CO2, driving a positive feedback on warming. On the other hand, if these populations cannot keep up with the influx of organic matter, organic matter burial rates will increase, driving a negative feedback on warming. Much of the microbial communities in Arctic sediments are unrelated to cultured microbes, so their potential role in organic matter remineralization is unknown. These types of organisms have been termed Microbial Dark Matter (MDM) since they are ubiquitous, enigmatic, and comprise some of the deepest evolutionary branches of life. I propose to use novel genetic, metabolic, and quantitative techniques to incorporate these MDM communities into models of carbon degradation in Arctic marine sediments in Svalbard, Norway.

Project: Forging the Missing Link: A Protein-Level View of Marine Microbial Ecology
 
Proteomic analysis — the identification of proteins in complex biological samples, and the quantification of protein-level gene expression — can enable quantitative, mechanistic connections between large-scale measurements of the chemical state of the oceans and of the genomic diversity in marine microbial ecosystems. In this project, we will use proteomics to gain new insights into two key aspects of marine microbial biogeochemistry: nitrogen limitation and anoxygenic phototrophy. Nitrogen availability is one of the most globally significant ecological pressures shaping the physiology and evolution of marine microbes, limiting primary production throughout much of the tropical and subtropical surface ocean. Since typically more than 80% of a cell’s nitrogen is in protein, N limitation is fundamentally a constraint on protein production, yet many questions remain about the molecular basis of this phenomenon in protein-level gene expression. Proteomic analysis can lend new insight into marine N limitation by quantification of community proteome abundance scales across spatial and temporal biogeochemical gradients. And while significant contributions of anoxygenic phototrophy to the metabolic energy budget of marine microbial communities (e.g., ATP production by proteorhodopsin-based phototrophy) have been hypothesized based on the abundance and diversity of sequences for these genes in marine metagenomic and metatranscriptomic datasets, testing this hypothesis has proven challenging. Measurement of the protein machinery that enables these metabolisms is a direct means to quantify their role in energy transduction. High-resolution proteomic measurements can also identify the primary organisms responsible for different modes of anoxygenic phototrophy in a range of oceanic habitats.

Project: Investigating the Microbiome of the Largest Known Bacteria
 
“Microbiome” is a term often given to the microbes associated with multicellular organisms, such as bacteria living in the human gut. While bacteria and archaea are known to live in association with other microbes, individual bacterial cells are not generally thought of as hosting a characteristic microbiome. My lab studies the largest known bacteria, Thiomargarita spp. These giant bacteria are involved in the biogeochemical cycling of carbon, sulfur, nitrogen, and phosphorus. They are also known for their involvement in the precipitation of calcium phosphate mineral deposits on the seafloor that are an important source of phosphorus for modern agriculture. Individual Thiomargarita cells can approach a millimeter in diameter, making them large enough to host extensive populations of other bacterial cells. New observations and molecular analyses suggest that smaller cells living in close association with Thiomargarita are important for the ecologies, physiologies, and biogeochemical influences of these giant bacteria. Interactions between Thiomargarita and other bacteria, as well as the biogeochemical influences they catalyze, will be investigated using a variety of interdisciplinary approaches ranging from genomics to geochemistry.

Project: Record of Microbial and Geochemical Co-evolution in Cyanobacterial Genomes
 
Cyanobacteria have the longest and most continuous fossil record of all organisms. This fossil record is used to time events in the evolution of different cyanobacterial groups, as encoded by the genomes of modern cyanobacteria, and reveal links between ecological, evolutionary and geochemical changes on Earth’s surface. However, current time-calibrated models of cyanobacterial evolution (molecular clocks) rely on a simple fossil morphology whose cyanobacterial origin and taxonomic associations have been questioned. Furthermore, most taxonomically diagnostic cyanobacterial fossils represent benthic organisms, but the sampling of modern cyanobacterial genomes is biased toward unicellular planktonic taxa.
 
The work proposed here will improve the sampling of the cyanobacterial phylum and the understanding of its evolution through three major aims:

  1. To sequence and annotate the genomes of 40-60 undersampled, but geologically and environmentally relevant cyanobacterial taxa;
  2. To reconstruct major genomic events (gene additions, duplications and losses) in cyanobacterial history;
  3. To correlate these data with major events in Earth history and correlate events in cyanobacterial evolution with the evolution of other organismal groups which may lack a fossil record.

 
Sequencing efforts will use pure cultures from existing collections, or sorted cells/filaments from enrichment cultures and field samples. Modern homologs of the most taxonomically diagnostic and oldest unambiguous cyanobacterial fossils are not well represented in culture collections, so these samples will be obtained in the field. The newly sequenced genomes will be used to re-estimate divergence times using a relaxed molecular clock and new calibration points will be provided. Based on this analysis, genome reconciliation will be performed. The new cyanobacterial molecular clock will be used to correlate major gene acquisitions, losses and duplications with known events in Earth history or to hypothesize currently unknown events based on genomic data.

Project: Growth Efficiency in the Mesopelagic at Station ALOHA
 
Organic carbon sinking from the ocean’s surface can meet three fates in the dark waters below: it can be assimilated into biomass, respired back to carbon dioxide, or continue sinking to the seafloor. Quantifying these fates—the ocean’s biological pump—is essential to constructing a carbon and energy budget for the ocean’s interior, and predicting changes in this budget into the future. The growth efficiency of microorganisms, that is, what fraction of the carbon they consume becomes cellular biomass, is an essential parameter to developing balanced budgets of carbon storage in the ocean’s interior. I will use novel cultivation techniques to establish bacterial and archaeal culture systems for understanding carbon, nitrogen, and energy flow in the mesopelagic at Station ALOHA. Efforts will be directed at determining quantitative physiological parameters such as growth efficiencies, substrate affinities, and temperature optima that can feed directly into predictive models of microbial ecosystem structure and function. By combining laboratory experiments, in situ experimentation, and time-series measurements of material export and microbial standing stocks, the SCOPE initiative provides a unique opportunity to undertake a systematic and integrated study of microbial growth efficiency in the mesopelagic at unprecedented resolution. The ultimate goal of this work is to construct an energy budget for the mesopelagic to understand and predict the efficiency of the biological pump.

Frank Stewart, Ph.D.

Georgia Institute of Technology

Frank Stewart is a marine microbiologist with broad interests in the genetic and metabolic diversity of ocean bacteria. His lab uses the tools of genomics and molecular biology to understand how marine microbes respond to environmental change and to symbiotic interactions with other organisms. In particular, research in the lab explores the diversity, evolution, and function of symbioses between bacteria and marine animals. This work targets diverse interactions, including those between deep-sea invertebrates and intracellular bacteria, as well as those within multi-species microbiomes on the surfaces and in the guts of reef corals and fish. The lab employs genomic and meta-omic methods to study these associations, often in collaboration with biogeochemists and ecologists. A second major research theme in the lab seeks to understand how declines in ocean oxygen content, due in part to climate change, affect microbial diversity and elemental cycling. This work focuses on major low-oxygen water masses in the Gulf of Mexico and the eastern Pacific Ocean, and involves a combination of oceanographic sampling, community genomics, biogeochemistry, and bioinformatics.

Project: Reef Fish Microbiomes: Models for Bacteria-Host Interaction in the Ocean
 
Animals harbor diverse and abundant microbial communities (microbiomes) that influence key aspects of host health, development, and behavior. The ecology and evolution of microbiomes remain almost completely unexplored for the largest and most diverse of the vertebrate groups, the teleost fishes. Coral reefs in particular support one of the richest assortments of fish among the major ocean ecosystems, with over 2500 species spanning a striking diversity of niches, reproductive and parental care strategies, and diet types. Reef fish microbiomes are hypothesized to harbor a wide diversity of uncharacterized bacterial lineages with potentially important roles as mediators of fish nutrition and disease prevention and as reservoirs for free-living or coral microbiome populations. The overarching goal of this project is to characterize the reef fish microbiome as a model for understanding microbe-animal interactions in the ocean. The research involves a combination of field sampling and laboratory experiments to understand the diversity of the reef fish microbiome and its relationship to host ecology and development, genomic analyses to identify key physiological properties and novel members of the microbiome, and experiments to quantify transmission routes of fish microbiomes and potential microbiome effects on fish behavior. This integrated approach will help identify connections between fish-associated and other microbial niches on reefs, as well as benefits of microbial-association, potentially including unrecognized contributions to fish immunity, digestion, and chemical signaling between individuals.
