4 Years On Campus Bachelors Program
The BS in Organismal Biology — Ecology, Evolution, and Behavior Option (ECEB) at Auburn University is designed for students who want to understand how organisms interact with one another and their environments, how natural selection shapes individuals and populations, and how behavior changes across ecosystems. The program combines biology with chemistry, mathematics, statistics and physics, making it particularly suitable for students interested in ecological research, evolutionary biology, animal behavior, conservation, environmental science and related graduate study.
Curriculum structure
Year 1: Students establish their scientific foundation through BIOL 1020 Principles of Biology, BIOL 1030 Organismal Biology, and their associated laboratory courses, while also completing CHEM 1030/1031 Fundamentals of Chemistry I and Laboratory and CHEM 1040/1041 Fundamentals of Chemistry II and Laboratory. BIOL 2100 Professional Development also introduces professional preparation early in the degree.
Year 2: The curriculum moves into the core concepts that define the ECEB option, with BIOL 3000 Genetics, BIOL 3030 Evolution and Systematics, and BIOL 3060 Ecology developing students' understanding of inheritance, evolutionary relationships and interactions between organisms and their environments. Students also build quantitative preparation through MATH 1610 Calculus I and STAT 2510 Statistics for Biological and Health Sciences, alongside CHEM 2030 Survey of Organic Chemistry.
Year 3: Students deepen their understanding of organisms through BIOL 4100 Cell Biology, a biology elective and advanced coursework in physiology such as BIOL 5130 Advanced Plant Physiology, BIOL 5210 Microbial Physiology, or BIOL 5240 Animal Physiology. PHYS 1000 Foundations of Physics and a quantitative biology elective add the physical and analytical skills needed for advanced ecological and evolutionary study.
Year 4: The final year emphasizes specialized ECEB study through BIOL 5650 Animal Behavior, Eco/Evo/Diversity electives, and additional Cell/Molecular/Microbiology or Physiology electives. Students also complete BIOL 4950 Senior Seminar, which brings together their advanced academic preparation, while BIOL 4AA0 Professional Development II supports their transition toward employment or further study. The complete ECEB curriculum totals 122 credit hours.
Focus areas:
Ecology, evolution, animal behavior, biodiversity, organismal biology, genetics, physiology, environmental science, quantitative biology, natural selection and organism–environment interactions.
Learning outcomes:
Students develop an understanding of organismal biology, ecological interactions and evolutionary processes while building laboratory, quantitative and scientific research foundations applicable to biological research and environmental science.
Professional alignment (accreditation):
STEM designated: Auburn University identifies Organismal Biology, including the Ecology, Evolution & Behavior Option, as a STEM-designated undergraduate program. Auburn's official program information does not state a separate professional accreditation specifically for the ECEB option.
Reputation (employability rankings):
Official Auburn sources do not publish a program-specific QS, Guardian or other employability ranking for the ECEB option. Auburn's College of Sciences and Mathematics reports 3,000 undergraduate students across the college and highlights its emphasis on research, hands-on learning and faculty mentorship; the Department of Biological Sciences reports 500+ undergraduates, 100+ graduate students and 40+ faculty members.
Students in the BS in Organismal Biology — Ecology, Evolution, and Behavior Option (ECEB) at Auburn University develop practical skills by combining laboratory-based biology with ecology, evolution, genetics, organismal biology and animal behavior. The curriculum includes dedicated laboratory courses such as Principles of Biology Laboratory, Organismal Biology Laboratory, Genetics Laboratory and advanced physiology laboratory work, while the option culminates in Animal Behavior and specialized ecology/evolution/diversity electives. Auburn also provides opportunities for faculty-mentored research, internships and field-based learning, giving students opportunities to apply biological concepts beyond the classroom.
Program-specific experiential opportunities include:
The BS in Organismal Biology — Ecology, Evolution, and Behavioral Option (ECEB) prepares students to understand organisms, ecosystems, evolution and behavior, creating pathways into ecology, conservation, environmental research and related biological sciences. Auburn specifically identifies this option as preparation for careers or graduate study in ecology, evolutionary biology, animal behavior, conservation and environmental research.
Career opportunities: Ecologist, Conservation Scientist, Wildlife Biologist, Environmental Researcher.
Career development and graduate outcomes:
Further Academic Progression: Graduates can continue into Auburn's M.S. or Ph.D. in Biological Sciences, where research-focused training is available across areas including ecology, evolution, conservation, behavior and other biological sciences. Auburn also offers an Accelerated Bachelor's/Master's (ABM) pathway for Organismal Biology students: eligible students can take three 6000-level courses worth 9 credits that count toward both degrees, develop undergraduate research into an M.S. thesis, and potentially complete the M.S. in 12–15 months.
