The Ecology of Food (E&EB 035)
Food and ecology are inextricably linked, both in producing domesticated food through agriculture and livestock and in harvesting wild plants and animals. Furthermore, the production and consumption of food have downstream consequences through energy consumption, food waste, trophic interactions, and the transportation of food around the globe. These topics link to many of the fundamental concepts of ecology, including population biology, the niche, trophic interactions, nitrogen cycling, and the effects on biodiversity. In this class, we explore these topics intensively through a combination of lectures, readings, and interactive field trips to on/near campus ecosystems, including the Marsh Botanical Gardens, the Yale Sustainable Farm, a nearby forest and salt marsh, and an orchard. Each week, we meet twice for 50 minutes for a combination of lecture and discussion and for 110 minutes for field trips, discussions, and guest lectures.
Enrollment limited to first-year students.

Plant Diversity & Evolution (E&EB 246/546)
This course has several, interrelated objectives. First, it serves as an introduction to the science of phylogenetics, providing an overview of both the theory and methodology involved in constructing phylogenetic trees, and how to use trees to study character and organismal evolution. For our second objective, we put this new framework to immediate use by using phylogeny to explore and illustrate 400 million years of land plant evolution, with emphasis on the diversity of flowering plants. The course examines major trends in plant evolution from functional, ecological, and bio-geographical perspectives. Students acquire a basic understanding of 1) phylogenetic approaches to comparative biology, 2) plant anatomy and morphology, 3) evolutionary relationships among the major land plant clades (with emphasis on the flowering plants), and 4) major evolutionary trends that have significantly shaped the diversity of plant life that we see today. The third and most important objective is to instill in students the ability to look at any biological problem through the lens of “phylogeny-colored glasses”- a powerful way to examine the complexity of life that surrounds (and includes!) us.

Life in Motion: Ecological and Evolutionary Physiology (E&EB 295)
Physiology is the study of the functions that organisms perform and how they use those functions to interact with the environment. To survive, grow, and reproduce, all organisms must acquire energy and avoid conditions that exceed their physiological limits. These interactions all involve motion—ions traveling across membranes, muscle fibers twitching, respiration, and locomotion, to name a few. In this course, we tackle physiological processes from both “bottom up” and “top down” approaches, with integration among these dimensions, to extract general physiological rules of life. Then, we link our discoveries to the broader context of ongoing global change, and consider whether and how organisms can physiologically respond to contemporary selective pressures. While the course focuses heavily on animal physiology, plants, fungi, and microbes are also featured.
Prerequisites: BIOL 101, 102, 103, 104, and CHEM 161, or permission of the instructor.

Philosophy of Biology (E&EB 321)
This course is an introduction to the philosophy of biology, with application to specific current problems. It focuses on two major strands of thinking seeking answers to fundamental and complementary questions: “How do we know?” (epistemology) and “What things really exist in the world?” (ontology). These two themes have the most important impact on the practice of science, as they pertain to the nature of the scientific enterprise and how it works (epistemology and philosophy of science), as well as what scientists consider part of reality (=science related ontology: unicorns and phlogiston NO; atoms, electrons, YES; but what about species and genes? Do they have the same status as atoms?). In each of these fields of philosophy we outline the main positions and then discuss how they apply to past and current debates in biology, in particular, but not exclusively, evolutionary biology.
Prerequisite: a semester of biology or a semester of philosophy.

Evolutionary Genetics (E&EB 322/622)
Genetic variation is the currency by which natural selection is translated into evolutionary change. In this course we dissect patterns of genetic variation using an evolutionary mindset to ultimately understand what shapes genetic variation in nature and the potential for species to adapt to new and changing environments. This class unites two foundational fields of evolutionary genetics; quantitative genetics (the study of the genetic basis of complex traits) and population genetics (the study of gene variant frequencies across time and space), with an ultimate goal of understanding evolutionary change in nature. Although this course is lecture based, there is much opportunity for hands-on learning. Students use real-life and simulated genetic data to map the genetic basis of traits and investigate the evolutionary forces responsible for shaping genetic variation in nature. We also discuss how quantitative and population genetics theory are applied to the modern genomic era, particularly in the context of detecting genomic signatures of adaptation. Lastly, we discuss the application of evolutionary genetics to human populations, including the usefulness and missteps of these applications for science and society.
Prerequisite: E&EB 225, Evolutionary Biology.

Prerequisites: E&EB 220, E&EB 225, and permission of the instructor.
Topics in Vertebrate Ecomorphology (E&EB 375)
Ecomorphology is a field that bridges ecology and evolutionary biology. Researchers studying organisms’ ecomorphology ask questions like, “What does the morphology of an organism tell us about its relationship with its environment” and “How are correlations between morphology and ecology influenced by behavior?” The answers to questions like these inform evolutionary hypotheses based on natural selection and help to explain the amazing diversity of life forms that surround us. In this course, we explore the links between organismal form, function, ecology, and evolution using a series of readings and guided discussions. Students also learn many of the fundamentals associated with crafting and revising publishable scientific writing–a must for those seeking research-based graduate education in the sciences. By the end of the semester, students refine their critical thinking and scientific writing skills, and they have a newfound awareness of one of the most integrative and fascinating branches of vertebrate biology.

Students may also work in areas related to environmental biology such as policy, economics, or ethics. The research project may not be a review of relevant literature but must be original. In all cases students must have a faculty sponsor who oversees the research and is responsible for the rigor of the project. Students are expected to spend ten hours per week on their research projects. Using the form available from the office of undergraduate studies or from the Classes server, students must submit a research proposal that has been approved by the faculty sponsor to the director of undergraduate studies, preferably during the term preceding the research. Proposals are due no later than the first day of the second week of the term in which the student enrolls in the course. The final research paper is due in the hands of the director of undergraduate studies by the last day of reading period in the term of enrollment.
Requires Permission from Instructor
Enrollment limited to EEB seniors. Two terms of senior research fulfills the senior requirement for the B.S. degree.

Responsible Conduct of Research (E&EB 545)
Graded Satisfactory/Unsatisfactory.
Requires Permission of the Instructor
This 5-week discussion seminar considers issues related to the responsible conduct of research. Topics addressed include: research misconduct, plagiarism, data acquisition and management, mentoring and collaboration, authorship and peer review, the use of animals and humans in scientific research, sexual harassment, diversity, and balancing professional and personal life.
This course takes place within E&EB 501: Advanced Topics. First-year students are required to register for both courses.
Biosocial Science (E&EB 636)
This seminar (with limited enrollment, but open to anyone) covers topics at the intersection of the natural and social sciences, including behavior genetics, gene-environment interactions, social epigenetics, and diverse other topics.
Biology of Insect Disease Vectors (E&EB 650)
Insects transmit pathogens that cause many emerging and re-emerging human and agriculture-related diseases. Many of these diseases, which are referred to as neglected tropical diseases (NTDs), have a dramatically negative impact on human health in the developing world. Furthermore, they cause indirect devastation by significantly reducing agricultural productivity and nutrient availability, exacerbating poverty and deepening disparities. This course introduces students to the biological interactions that occur between major groups of important disease vectors and the pathogens they transmit. Lectures cover current research trends that relate to the ecology and physiology of insect vectors. Course content focuses on how these aspects of vector biology relate to the development and implementation of innovative and effective disease-control strategies.
Prerequisite: full year of college/university-level biology, or permission of the instructor(s).
Foundations of Ecology (E&EB 712)
This seminar course familiarizes students with foundational concepts and themes in ecology and how they have changed over time. Each week we read and discuss two papers: one classic paper selected from the recently published volume Foundations of Ecology II: Classic Papers with Commentaries (Eds. Miller and Travis, 2022) covering the period 1970–1995, and one related contemporary paper published after 2010. We discuss how the concepts and themes introduced in classic papers have influenced the field of ecology and consider how new tools, data, and insights have advanced, diminished, or changed their impact. The Foundations book covers many topics, arranged into six core areas. Readings cover all six areas, but the included content varies depending on the interests of the class. Students are responsible for choosing one classic paper from Foundations, pairing it with one contemporary paper and leading the discussion during the class meeting. Students also submit short weekly “reflections” in response to a prompt.
From Biodiversity Science to Conservation Impact (E&EB 713)
We dive into the scholarship and careers of E.O. Wilson and Thomas Lovejoy and explore how they succeeded in bringing scientific insights and evidence into the practice of conservation. We discuss examples of their primary research, recent studies following up on their ideas, and biographic work. We attempt to link their original contributions and ideas to the conservation actions and outcomes they inspired and hear from those who worked closely with them. In a final segment, we critically relate their scientific legacy to the additional, new challenges and opportunities for equitable, fair and effective conservation solutions in the 21st century.
Structuralism and Macroevolution (E&EB 717 )
A seminar course discussing the philosophical roots of and empirical research in structuralism and macroevolution. We read selected papers in philosophy of evolutionary biology, comparative phylogenetic methods, macroevolutionary studies, and the role of natural history in evolutionary thought. Each topic is paired with readings on empirical research that involves similar issues. The course concludes with a short writing assignment that analyzes a contemporary question in macroevolution or structural/organismic research.
Foundations of Terrestrial Ecology (E&EB 721)
Intended for graduate students, this seminar course brings a historical perspective to understanding current questions and approaches in terrestrial ecology, ranging from evolutionary, community, landscape, to ecosystem ecology. We read and discuss foundational papers and related current papers, and we identify future directions, opportunities, and challenges for the different sub-fields. The course allows students to critically examine and engage with some scientific work that has laid the findings and concepts that are foundational as they develop conceptual and methodological approaches to their own research. Starting in weeks three or four, each student takes a turn leading discussion and selecting a relevant current paper to that week’s topic. Students write a total of seven précis on the topics of their choosing, with at least two completed by week six.
Comparative Genomics (E&EB 723)
The field of evolutionary biology is increasingly drawing on genomic data, and the field of genomic biology is becoming more evolutionary as genomes are sequenced for a broader diversity of organisms. This course focuses on the evolution of genome sequence and function at macroevolutionary timescales, with an emphasis on building practical computational skills for genomic and phylogenetic comparative analyses. The focus is more on using phylogenies to understand genome evolution than on using genomes to build phylogenies.
Scientific Writing for Ecology and Evolutionary Biology (E&EB 725)
This course will provide guidance and practice for graduate students in grant and manuscript writing in the fields of ecology and evolutionary biology. Students will produce one grant application (NSF GRFP/DDIG or similar) and one manuscript for publication (on a topic of their choice, to contribute to their thesis or other ongoing work).
Forgotten Grassy Ecosystems (E&EB 750)
Grassy ecosystems—including savannas and grasslands—have historically been relatively undervalued, often confused and misclassified as forests. This seminar includes weekly readings and discussion about the world’s grassy ecosystems in general and focusing on regional examples of overlooked savannas and grasslands. This seminar is intended for Ph.D. students. It is open to master’s students and undergraduates by permission of the instructor only, based on a one- or two-paragraph description of interest in the course.
Ecology of Landforms (E&EB 762)
This course is a combined graduate research seminar and research practicum that explores the linkage between ecological and geomorphic processes—between biology at Earth’s surface and the shape and structure of that surface. This course is centered around two skill-building activities: (1) a series of presentations in which students deliver short mock lectures, lead subsequent discussion, and receive constructive feedback from the class; (2) a series of quantitative workshops (held in alternate weeks) in which the class collaboratively designs and codes a model or model(s) that relate to ecological and geomorphic processes. A primary focus of this course is understanding how biogeochemical cycles play out across hillslopes, watersheds, and fluvial landforms. Depending on student interest we may also address questions relating community ecology, population ecology, or evolutionary processes to landscape structure. Students should expect to hone their presentation skills and quantitative toolset, particularly with respect to spatial analysis and numerical modeling.
Life in the Anthropocene (E&EB 804)
All living things exist in an era of unprecedented global-scale environmental change. Global change encompasses numerous, often interconnected phenomena that are currently impacting organisms. These include rising temperatures, ocean acidification, habitat loss and degradation, overexploitation, novel pathogens, and toxin exposure. This course focuses on global change from the perspective of the organisms themselves. Our goal as biologists is to understand the magnitude of the problem by addressing the following questions: (1) What are the principal ways in which organisms are being challenged due to human impact? (2) What mechanisms are there for organisms to adaptively respond to these challenges? and (3) What can we do to help organisms? To address these questions, we delve into the scientific literature on distinct topics related to global change, discussing one of these topics in each class meeting. Key papers from the literature are assigned to help guide discussion. This course is discussion-based and interactive; each week a student leads discussion along with the instructor. A secondary goal of the course is to help students improve their written communication abilities, either through a traditional term paper or something else, like a grant application or a dissertation chapter. Depending on the number of students and their goals, we might tackle a review paper together, with the goal of obtaining a peer-reviewed publication.
Prerequisites: introductory biology and evolution.
The Ecology of the Great Pandemics (E&EB 830)
In this course we examine principles of the ecology of infectious disease in light of three pandemics: the 1918 influenza pandemic, the HIV/AIDS pandemic, and the COVID-19 pandemic. The course covers principles of zooneses, disease emergence, herd immunity, basic vaccinology, and other fundamental concepts. It also focuses on social and cultural factors that fomented these pandemics.
Adaptive Radiation (E&EB 834)
One of the most striking patterns of biodiversity is its uneven distribution across the tree of life. Theory suggests that this disparity in diversity reflects feedback between ecological and phenotypic evolution. Adaptive radiations, the rapid multiplication of species into distinct ecological niches, is a key example of this phenomenon. While studies about adaptive radiation have grown exponentially over the past decades, fundamental questions remain. For example, how does phenotypic diversification unfold during radiation? How do species interactions shape species richness in adaptive radiation? Do adaptive radiations play out in parallel across continental and island contexts, or are there repeatable differences among them? The goal of this course is to critically dissect the field of adaptive radiation. Specifically, we unpack its major features and identify unresolved lacunae. To do so, we delve into the scientific literature on distinct topics related to adaptive radiation. Key papers from the literature are assigned to help guide discussion. We begin with a brief survey of recent syntheses on adaptive radiation to refresh our understanding and, most importantly, identify key gaps in empirical knowledge. Then, we explore several studies focused on less-studied axes of adaptive radiation to catalyze our thinking.
Prerequisites: BIOL 103/104 (or equivalent) and E&EB 525 (or equivalent).
The Behavioral Immune System (E&EB 854)
Behavior is the first line of defense against parasites and pathogens. Behavioral defenses allow organisms to minimize contact with infectious agents, and the concept of the “behavioral immune system” was developed to encompass a range of evolved behaviors that help minimize the fitness costs of infection. The COVID-19 pandemic has made the term “social distancing” a household term; however, distancing and many other avoidance strategies are employed by a wide range of organisms to combat infectious agents. In this seminar, we examine our current understanding of the behavioral immune system across the diversity of animals, including humans. Specifically, we explore: (1) the mechanisms of behavioral immunity; (2) the ecological, evolutionary, and epidemiological consequences of these behaviors; and (3) key costs of behavioral immunity that maintain intra- and interspecific variation. To do this, we discuss and synthesize the scientific literature on the behavioral immune system, drawing parallels to work on the physiological immune system. The first weeks of the course focus on instructor-selected papers, and subsequent weeks incorporate student-selected papers.
Special Topics in the Ecology and Evolution of Infectious Diseases (E&EB 856)
Historically, pathogens and the diseases they cause were viewed largely from a biomedical perspective focused on interactions between pathogens and their human hosts. However, in the last few decades, the importance of studying pathogens from an ecological and evolutionary perspective has gained significant traction. These perspectives inform our understanding of almost all aspects of pathogen-host interactions from transmission dynamics and zoonotic disease spillover to the evolution of virulence and drug resistance. In this seminar, we dissect current and classic literature on the ecology and evolution of infectious diseases. Specifically, we: (i) discuss fundamental concepts in the field; (ii) identify persistent knowledge gaps; and (iii) explore opportunities for linkages between ecological, evolutionary, and biomedical perspectives.
Ecosystem Dynamics of Nature-Based Climate Solutions (E&EB 862)
Nature-based climate solutions have gained increasing attention in the past decade as possible contributors to reducing our net carbon emissions to the atmosphere, without necessarily reducing gross emissions. Prominent nature-based solutions include forestation (reforestation, afforestation, plantation forestry), avoided deforestation, and soil carbon sequestration. This seminar includes weekly readings and discussion around themes in the management of ecosystem carbon storage.
This seminar is intended for Ph.D. students. It is open to master’s students and undergraduates by permission of the instructor only, based on a one- or two-paragraph description of interest in the course.
Evolutionary Architects: Organisms as Targets and Agents of Natural Selection (E&EB 865)
Organisms are routinely faced with many abiotic and biotic pressures that impact their survivorship, growth, and reproductive success. For example, a lizard’s ability to perform fitness-based tasks (like foraging or predator evasion) is limited by the thermal dependence of its performance, its hydric and metabolic economy, and its morphological dimensions. Yet, organisms are not exclusively at the whim and mercy of their surroundings. Of key importance is the preeminent role that organisms exert on their own selective environments and, correspondingly, on their evolution. This course considers the diverse ways in which organisms engineer their own evolutionary trajectories. Some of the topics we cover include niche construction, extended phenotypes, behavioral drive, the Bogert effect, and adaptive virulence (particularly in the context of the COVID-19 pandemic).
Open to upper-level undergraduates who have taken BIOL 103, BIOL 104, and E&EB 225 (or the equivalent).
Speciation & Adaptation Genomics (E&EB 872)
Speciation and adaptation are two fundamental processes that generate the diversity of life seen on earth to date. This graduate-level seminar course will explore the evolutionary mechanisms responsible for these phenomena by delving into the primary literature to explore classic examples of adaptation and speciation using a genetics and genomics lens.
