How the grade is built
| Component | Weight | Notes |
|---|---|---|
| Exam 1 Β· Thu Sep 24 | 15% | Definitions, multiple-choice, short answer, and longer essay questions. Drawn from lectures, readings, and class activities β and lab material may appear on lecture exams. Each exam covers its own block; none of them is cumulative. |

| Final exam Β· Tue Dec 15 | 15% | |
| Final project Β· due Tue Dec 8 | 15% | Presented informally in small groups on Dec 8. The two writing guides above are aimed squarely at this. |
| Lab | 40% | Lab assignments, reports, and participation. Lecture material may appear in labs. |

Safety nets β use them deliberately, not casually
- One exam can be made up β for documented conflicts (university athletics, sudden illness, family emergency).
- One lab assignment is dropped β same rationale.
- Late work: β5% of the assignment value per day (a 20-point assignment loses 1 point per day).
- Alert him as soon as possible β beforehand where you can β with formal documentation.
Note: there is no "lowest exam dropped" policy, and exams are not stated to be open-note. Do not plan around either.

What actually earns the grade
Manning's own tips for success
"Ecology is not about memorizing terms, but it is about understanding processes." Build that into how you use this site: after every flashcard run, force yourself to explain the mechanism out loud, not just recite the definition.
- Attend and participate. In-class exercises are graded β completion or content, at his discretion β and are how you earn attendance credit. He also drops subtle hints about what is on exams.
- Take the readings seriously. Primary and popular readings go beyond textbook and lecture, are posted to Canvas, announced in advance, and likely discussed in class β and they are fair game on exams.
- Form a study group. He explicitly recommends making a habit of discussing lecture concepts as a team.
- Do the end-of-chapter conceptual questions in the textbook. He names these directly as exam practice.
- Slides are on Canvas β but they are the skeleton, not the course. Being absent costs you the rest.
Key dates β Fall 2026
From the Canvas schedule of topics. Manning notes the schedule is subject to change (weather, etc.) and that Canvas is the authoritative copy.
3 exams + a project
- Exam 1 β Thu Sep 24 Β· Weeks 1β5
- Exam 2 β Tue Nov 3 Β· Weeks 6β10
- Final projects due β Tue Dec 8, with informal small-group presentations in class
- Review session β Thu Dec 10
- Final exam β Tue Dec 15
The final is not cumulative
The Dec 15 final covers only the final third of the course material β that is roughly Nov 5 β Dec 3: ecosystem ecology (food webs, energy flow, production, decomposition, biogeochemical cycling), global change agents, restoration, and conservation biology.
Plan accordingly: Exams 1 and 2 are where the earlier material gets tested, and it does not come back. Don't over-invest in re-reviewing weeks 1β10 in December.
Breaks
- Tue Oct 20 β Fall break
- Thu Nov 26 β Thanksgiving
First class Tue Aug 25. Last content day Thu Dec 3.

How to read this schedule
- Each exam is a clean block. Exam 1 = weeks 1β5, Exam 2 = weeks 6β10, Final = weeks 11β15. Nothing is re-tested, so bank each block once and move on.
- Two textbooks, one topic. Stiling is the recommended buy; EFA is free and embedded here. When a topic lists both, read whichever explains it better for you β they cover the same ground.
- The heaviest stretch is Sep 29 β Oct 29 β five straight topic pairs (species interactions β community ecology) with no break until Oct 20, all landing on Exam 2.
- Ecosystem ecology is both the final's whole content and Manning's research area. Nov 5 β Dec 3 is where his emphasis and your last exam overlap completely.
Know your instructor
Dr. David Manning
Freshwater and ecosystem ecologist. Works on streams and rivers: nitrogen and phosphorus dynamics, detritus-based food webs, organic-matter breakdown, and how watershed land use β agricultural, urban, forested β drives nutrient loading downstream.
What to expect from that: aquatic systems carry real weight alongside terrestrial ones; ecosystem-level nutrient cycling and stoichiometry are likely emphasized more than in a typical intro course; and the "humanβenvironment interactions" thread in the syllabus will lean on land use, eutrophication, and water quality. Expect primary-literature readings from this space.
Practical notes
- Email is the channel β roughly 24 h weekday turnaround.
- Open office door means come in. He states it explicitly β help, conversation, whatever.
- Documented conflicts: tell him beforehand and bring formal documentation.
- Lab and lecture are not siloed β each shows up on the other's assessments.
- Accessibility accommodations run through ASC (104 H&K Β· 402.554.2872) β request well in advance.
