  • Ecology | Ecology, Evolution, and Marine Biology | UC Santa Barbara
    Ecologist use both theory and empiricism and work in the field and the laboratory Ecologists in EEMB strive to generate new understanding of the relationship between organisms and their biotic and abiotic environment using two overlapping approaches One is driven by the attempt to generate and test general ideas in ecology EEMB faculty have made important contributions to the development of general ecological theory and testing it with studies of population regulation community structure and ecosystem function The second approach focuses on problems specific to particular ecological systems such as deserts the tundra the coastal ocean lakes and streams EEMB ecologists are providing the scientific understanding necessary for the development of solutions to some of society s most critical environmental problems including biodiversity loss organismal responses to environmental change eutrophication of inland waters disease spread and dynamics effects of ocean acidification and species invasions Research Areas Disease Ecology Disease ecology is the study of the ecological principles that determine the spatial and temporal patterns of disease incidence prevalence and impacts on their host populations Ecosystem Ecology Ecosystems function as an integrated system in which organisms interact with each other and with their physical environment moving energy carbon and nturients through

  • Evolution | Ecology, Evolution, and Marine Biology | UC Santa Barbara
    insight by seeing biological problems in four dimensions Explaining how differences among organisms arise from DNA differences for example is central to the goals of evolutionary biology Understanding biodiversity from diversity in human drug response to diversity of species in undisturbed ecosystems requires a better understanding of how changes in DNA lead to changes in organisms Evolutionary biologists in UCSB persue this challange from many angles including population genetics evolutionary physiology and phylogenetics Predicting ecological responses to global change also hinge on an understanding of evolution Protecting ultra diverse habitats like coral reefs endemic local ecosystems such as serpentine plants in California and agro ecosystems that feed the human population all depend on understanding ecological interactions However understanding the current network of species interactions is insufficient these interactions change over time due to evolution The integration of ecology and evolution is therefore a core goal of our department For these and other reasons evolutionary biologists at UCSB are integrating an understanding of the causes of evolution with the consequences of those processes Research Areas Evolutionary Ecology Evolutionary ecology integrates population genetics demography and ecology with the study of natural selection and other mechanisms to detect adaptation in wild populations species

  • Organismal Biology | Ecology, Evolution, and Marine Biology | UC Santa Barbara
    scientists working in the field of integrative organismal systems discover and characterize the diversity of morphology and behavior across the domains of life and use quantitative analysis to explain the evolution and function of these discoveries The tremendous diversity of form and function in nature necessitate both an in depth focus on model systems and a comparative phylogenetic approach encompassing broad groups of taxa The goal of research in the broad area of organismal biology is to explain the structure and function of organisms in terms of their evolutionary history and ecological context This includes the use of comparative phylogenetic approaches to the study of development physiology and functional form Integrative organismal systems is a highly integrative field linking organismal and evolutionary biology to ecological science Research Areas Behavior The study of how variation in behavior relates to variation in survival reproduction and evolutionary fitness linking natural selection on behavioral strategies to ecological and environmental variation Botany EEMB plant scientists study invasive species plant effects on soil processes adaptation controls over diversity phenological responses to climate change and the molecular basis of evolution Microbial Ecology EEMB s microbial ecologists study the ecological and evolutionary relationship between microbial organisms and how

  • How Chemicals Affect Ecosystems: A UCSB theoretical ecologist receives an EPA grant to study the biological and ecological consequences of exposures to chemicals in the environment | Ecology, Evolution, and Marine Biology | UC Santa Barbara
    better understand biological and ecological consequences of exposure to metals nanoparticles and certain flame retardants in industrial and consumer products Such materials could pose a threat to human and environmental health Most ecological risk assessments of chemical stressors are motivated by the societal need to avoid unacceptable impacts on natural populations and ecosystems from exposure to manufactured chemicals said Nisbet a professor in UCSB s Department of Ecology Evolution and Marine Biology A major challenge is that ecological change usually occurs on long time scales and involves many interacting species but the data available for risk management typically comes from short term studies on individual organisms or on biochemical processes Nisbet s project Dynamical Systems Models Based on Energy Budgets for Ecotoxicological Impact Assessment is expected to enhance the understanding of how the effects of exposure to chemical stressors are expressed ecologically New mathematical models will be developed with feedback representing physiological control processes within an organism and interactions among species in an ecosystem The anticipated expected outcome is an enhanced and improved ability to identify key toxic mechanisms within individual organisms and to make quantitative predictions of the implications for the sustainability of populations Nisbet said If models are

    the things they eat One creature s prey is another creature s predator while some organisms consume one type of food in their juvenile stage and another as adults Thousands of modeling studies have been developed to describe different consumer resource relationships in the natural world but a new general consumer resource model developed by ecologists affiliated with the National Center for Ecological Analysis and Synthesis NCEAS at UC Santa Barbara captures the underlying structure of all ecological food webs and provides a framework from which new models that share the same assumptions and mathematics can emerge It rolls a century s worth of food web mathematics into a single model said U S Geological Survey UCSB ecologist Kevin Lafferty lead author of the report published in Science Magazine He and co authors from Stanford University Princeton University Santa Fe Institute and the University of Bristol in the United Kingdom formulated a mathematical model that outlines behaviors circumstances and effects of the various strategies employed by consumers from social predators such as the enormous killer whale to tiny parasites and pathogens There s a long history in ecology of striving for generality through the use of simple models because models

  • In Living Color: UCSB’s Debora Iglesias-Rodriguez is thrilled to study the chalk-making phytoplankton turning the ocean turquoise in the Santa Barbara Channel | Ecology, Evolution, and Marine Biology | UC Santa Barbara
    chalk producing phytoplanktonic organism called a coccolithophore But what makes these otherwise invisible life forms suddenly visible It s their sudden abundance When coccolithophores are numerous they turn the ocean surface turquoise white and can easily be seen via satellite Coccolithophores make chalk calcium carbonate internally in the organelles within the cell and they push it outside the cell membrane said biological oceanographer Debora Iglesias Rodriguez a professor in UCSB
