How does a swarm of honeybees collectively decide on a new site for their hive? When a mother mouse protects her young, are her behaviors genetically determined? Why do ravens share food with each other? This course is an introduction to behavioral ecology, which asks why animals act the way they do, how their behaviors have been shaped by natural selection, and how these behaviors influence their surroundings. We will first discuss behaviors at the individual level, then move to reproductive behaviors. The final section of the course will focus on social evolution, the origins of cooperation, and human behavioral ecology.

This course explores the mechanisms of animal function in the contexts of evolution, ecology and behavior. We will cover the physiological bases of osmoregulation, circulation, gas exchange, digestion, energetics, motility, and neural and hormonal control of these and other processes in a variety of vertebrate and invertebrate animals, thereby revealing general principles of animal physiology as well as specific physiological adaptations to differing environments.

Current and classical theoretical issues in ecology and evolutionary biology. Emphasis will be on theories and concepts and on mathematical approaches. Topics will include population and community ecology, immunology and epidemiology, population genetics and evolutionary theory.

An introduction to the biology of viruses, bacteria, fungi, protozoa, worms, arthropods, and parasitic plants. The major emphasis will be on the parasites of animals and plants, with further study of the epidemiology of infectious diseases in human populations. Studies of AIDS, anthrax, and worms, and their role in human history will be complemented by ecological and evolutionary studies of fig wasps, measles, myxomatosis, and communities of parasitic helminths. The course combines lectures with daily field laboratories to explore the dynamics and abundance of parasite in a variety of host species in the Mpala Research Centre in Kenya.

In this course, students will learn laboratory techniques to construct genomic libraries for reduced representation genome sequence methods and apply evolutionary theory to empirical genomic data. Students will complete independent projects that address ecological and evolutionary questions, with a final report to immerse themselves in the professional-level practice of scientific writing. We will discuss evolutionary topics through lectures, discussions, and assigned readings. Each student project will tackle a different question rooted within molecular ecology and produce a written report formatted for a peer-review journal.

The pre-European history of Amerind cultures and their associated environments in the New World tropics will be studied. Topics to be covered include the peopling of tropical America; development of hunting/gathering and agricultural economies; neotropical climate and vegetation history; and the material culture and social organization of native Americans. Field and laboratory experiences will incorporate methods and problems in field archaeology, paleoenthnobotany and paleoecology, and archaeozoology.

Tropical Biology 338 is an intensive three-week field course based in lowland rainforest in Panama. The origins, maintenance, and major interactions of terrestrial biota in tropical rainforests will be examined. The course will involve travel to three different field sites, field journaling, and completion of independent field based research projects.

This field and lecture course provides an in-depth introduction to the biology of tropical coral reefs, with an emphasis on reef fish ecology and behavior. Each day begins with a lecture, followed by six to eight hours on the water, and ends with data analysis, reading and a discussion of recent papers. Students learn to identify fishes, corals and invertebrates, and learn a variety of field methods including underwater censusing, mapping, videotaping and the recording of inter-individual interactions. Each year group projects will vary depending on previous findings and the interests of the faculty.

Terrestrial paleoecology is the study of vegetation and animals in ancient ecosystems. The paleoecology of eastern Africa is significant because it can shed light on the potential role that climate played in human evolution. This course aims to teach students the principles of paleoecology primarily through fieldwork, lab work, and research projects. In the first half of the course, students will be introduced to basic methods in the modern Mpala ecosystem. In the second, they will explore the rich record of human evolution in the Turkana Basin. Students will study bones, teeth, plants, or soils to reconstruct modern and ancient ecosystems.

This course will cover genomic tools that can be used to study ecology and evolution in the field. Students will use the latest sequencing technologies (Illumina and Oxford Nanopore) to study ecological communities. Together, the students will design a set of studies that will use molecular barcoding to assess the composition of both animal and bacterial communities. They will conduct field trips to collect target samples for our experiments, and then they will extract DNA, amplify target loci, sequence their samples in the field, and analyze the resulting data. This course is offered as part of the semester abroad program in Kenya.

How do genes and neural circuits encode behavior? How have genes and circuits evolved to generate the incredible diversity of behaviors we see across the animal kingdom? This course will explore these questions with emphasis on recent advances in the primary literature. Each class will focus on a specific behavior with a lecture introducing what is known about its genetic and neural basis followed by a discussion of a paper that builds on that knowledge to examine how the behavior evolves. A major goal of the class will be to learn how to critique contemporary research, generate new hypotheses, and design experiments to test those hypotheses.

Introduction to concepts, methods, and material of comparative natural history, with mammals as focal organisms. Perspectives include morphology, identification, evolution, ecology, behavior and conservation. Observations and experiments on a variety of species in different habitats and at a range of scales will provide insights into the adaptive value and underlying mechanistic function of mammalian adaptations. This course will be taught simultaneously in Panama and Kenya as part of EEB's semester abroad programs

Students will be immersed in an intensive field experience in Kenya gaining sophisticated training in fieldwork and biological research on African animals and ecosystems. In addition to this training, participants will observe and study organisms ranging from acacia ants to giraffes, go-away-birds to zebras. The course is designed to give students a broad, hands-on understanding of ecology, evolution, and conservation. Lectures include core topics in ecology and evolution. Students will gain experience with experimental design, data collection, and analysis. Limited to students in the Tropical Biology and Sustainability Program in Kenya.

This lecture and discussion course will combine topics from graphic novels and science fiction with biological and technological research to explore bizarre phenomena in the natural world and delve into basic scientific theory and principles. The range of topics covered will include evolution, genetics, physiology, biomechanics, brain-machine interfacing and artificial intelligence among others. Lectures serve to introduce each topic, merging science fiction with contemporary issues and theories in biology, while discussions will focus in depth exploration of scientific and sociocultural concepts through the reading and literary analysis.

Intensive three week field course during (dates to be determined) in a suitable tropical locality. Readings, discussions, and individual projects. The content and location are varied to suit the needs of the participants. Students provide their own travel funds
