Course Description

Population, community, and ecosystem ecology studied through field sampling design, species surveys, and habitat assessment, with a weekly three-hour field laboratory. ENVS 201 investigates fundamental principles of ecological systems from populations and communities to ecosystems and landscapes, emphasizing quantitative field methods and experimental design. Students examine life-history strategies, population demography, competitive and trophic interactions, biogeochemical cycling, and landscape fragmentation. Through weekly field laboratories across regional forest, wetland, and riparian habitats, you will master flora and fauna survey methods, vegetation sampling transects, mark-recapture techniques, and multivariate ecological data analysis.

Prerequisites

ENVS 101 and BIO 101.

Measurable Student Learning Outcomes

Upon successful completion of ENVS 201, students will be able to:

  1. Model Population Demography and Dynamics: Construct life tables, estimate survival and fecundity rates, and model exponential, logistic, and stage-structured population growth.
  2. Design Field Ecological Sampling Protocols: Implement randomized, stratified, and transect-based field sampling strategies to quantify plant and animal abundance, density, and distribution.
  3. Quantify Biological Diversity and Community Structure: Calculate species richness, Shannon-Wiener diversity, evenness indices, and community similarity metrics from empirical field survey data.
  4. Analyze Trophic Dynamics and Nutrient Fluxes: Quantify ecological energetics, trophic efficiency, primary productivity, and nutrient budgets across forest and aquatic ecosystems.
  5. Evaluate Landscape Ecology and Habitat Fragmentation: Analyze patch size, edge effects, wildlife corridors, and metapopulation dynamics to assess conservation reserve designs.
  6. Communicate Scientific Field Research: Synthesize empirical ecological field data into professional, peer-reviewed format research papers adhering to Ecological Society of America standards.

Course Policies

Attendance Policy

Field ecology requires prompt and reliable attendance. Laboratory sessions begin at 8:00 a.m. sharp with vans departing from Meridian Science Center for regional field sites; tardiness means missing transportation and earning a zero. Notify Dr. Moss in advance of medical or emergency absences. More than two unexcused lab absences results in an automatic grade of F. Students who miss the first two class meetings without notifying the instructor may be dropped. Students may miss class for religious observance without penalty if they notify the instructor in writing within the first two weeks of the semester (by Wednesday, September 9, 2026). Absences for university-sponsored activities (athletics, performances, conferences) are excused with a letter from the sponsoring office at least one week in advance.

Late Work Policy

Field reports submitted past the Friday deadline lose 10% per day and will not be accepted more than three days late. Problem sets and data exercises submitted late lose 20% and cannot be submitted after answer keys are published. The lowest problem set score is dropped.

Fieldwork Gear and Inclement Weather Policy

Field laboratories take place rain or shine across muddy, wooded, and wetland terrains. Students must dress in durable outdoor clothing, long pants, waterproof hiking boots or rubber mud boots, and weather-appropriate rainwear. Field equipment, safety goggles, and high-visibility vests will be provided.

Final Exam Policy

The final examination (Tuesday, December 15, 2026, 10:30 a.m.–12:30 p.m.) is scheduled by the University Registrar and can't be moved without the Dean's written approval (Faculty Handbook §5.5). A student with three or more final exams on the same calendar day may reschedule one of them. Requests go to the instructor of the middle exam by the last day of classes. For this term, send the request by Wednesday, December 9, 2026 (Student Handbook §6.4).

Academic Integrity

Alkimi University is an academic community devoted to rigorous scholarship, open intellectual inquiry, and uncompromising ethical conduct. All students are subject to the regulations of the Alkimi University Academic Integrity Policy. Academic dishonesty—including plagiarism, cheating on examinations, unauthorized collaboration, fabrication of empirical data, and unauthorized submission of academic work generated by artificial intelligence—undermines the integrity of the university and carries severe disciplinary sanctions. Sanctions range from a failing grade on an assignment or exam to an administrative course failure recorded as an 'XF' on the official transcript, academic suspension, or expulsion. Suspected violations are formally investigated and resolved through the Office of Academic Integrity in accordance with Faculty Handbook §6. For detailed information, consult the Office of Academic Integrity, Lovell Hall 315, (555) 555-0163, integrity@university.alkimi.ai.

Accessibility Services

Alkimi University is committed to providing equitable educational access and reasonable accommodations for all students with documented disabilities, including physical, sensory, psychological, learning, and chronic health conditions. Students requesting academic accommodations must formally register with the Office of Accessibility Services, Harlan Hall 204, (555) 555-0155, access@university.alkimi.ai. Once approved, students will receive an official Faculty Accommodation Letter detailing approved accommodations. Students should present this letter to the instructor as early in the semester as possible, and at least one week prior to any exam or assignment requiring accommodation. Accommodations cannot be applied retroactively.

Student Wellness and Mental Health

Your physical health, psychological well-being, and mental health are essential to your academic success. If you experience heightened stress, anxiety, depressive symptoms, personal trauma, or academic burnout, free, confidential counseling and medical care are available through the Hollis Health & Counseling Center, located in the Hollis Center. Routine appointments are available Monday–Friday 8:00 a.m.–6:00 p.m. and Saturday 10:00 a.m.–2:00 p.m. during the semester by calling (555) 555-0190 or emailing health@university.alkimi.ai.
