The Hogsback Project
Where Ants Build Student Scientists
When Ants Became the Ultimate Teachers
Imagine an entire university curriculum built around the humble activities of ants. At the University of Montana Western, this isn't science fiction—it's a revolutionary educational model transforming how students experience science.
The Hogsback Project has turned Pogonomyrmex occidentalis (western harvester ants) into living textbooks, creating a multidisciplinary research ecosystem where biology majors analyze ant behavior, geology students study soil chemistry, and math majors build predictive models—all from the same field site.
By embedding experiential learning into the DNA of general education, this initiative has engaged 536+ students across 34 classes since its inception, proving that when education escapes the classroom, curiosity takes root 1 3 .

The Hive Mind: How Ants Connect Disciplines
The HUB Research Architecture
Traditional research often isolates disciplines. The Hogsback Project flips this model with its "HUB research" framework—a central, real-world investigation (ants' environmental impact) that branches across courses.
Block Scheduling Acceleration
Students immerse in one course per 18-day "block," enabling intense field and lab work. A geology student collects soil samples in the morning; by afternoon, a biology peer analyzes how ant activity altered its composition 1 .
Cascading Knowledge
Early courses build foundational skills (e.g., soil pH testing). Advanced classes tackle complex questions (e.g., modeling how ant nests affect water infiltration) 1 .
Why Harvester Ants?
These insects are ecosystem engineers:
In the Field: Decoding Ant Engineering
The Foraging Behavior Experiment
A multidisciplinary team investigates how temperature shapes ant activity and soil nutrients.
Methodology:
- Site Mapping: Geology students grid the research area, classifying soil types (sandy vs. loamy) and nest locations 1 3 .
- Activity Monitoring: Biology teams record ant movements hourly (6:00 AM–8:00 PM), tracking foraging speed and food transport 3 .
- Soil Sampling: At depths of 10cm, 30cm, and 50cm, samples are extracted near nests and control sites for nutrient analysis 1 .
- Microclimate Logging: Sensors buried near nests record temperature/humidity every 15 minutes 3 .
Results & Analysis
| Ground Temp (°C) | Ants Observed (per 10 min) | Foraging Speed (cm/sec) |
|---|---|---|
| 15–20 | 8.2 ± 1.1 | 1.1 ± 0.3 |
| 20–25 | 23.7 ± 2.4 | 2.6 ± 0.4 |
| 25–30 | 16.3 ± 1.8 | 1.9 ± 0.2 |
Ant productivity peaked at 20–25°C, declining sharply above 30°C—a finding crucial for predicting climate change impacts 3 .
| Sample Site | Nitrogen (mg/kg) | Organic Matter (%) | Porosity (%) |
|---|---|---|---|
| Near Ant Nest | 12.4 ± 0.9 | 4.7 ± 0.3 | 35.2 ± 1.6 |
| Control (No Nest) | 7.1 ± 0.6 | 2.1 ± 0.2 | 22.8 ± 1.1 |
Nest sites showed 75% higher nitrogen—evidence of ants' role in soil fertility 1 3 .

Beyond the Anthill: Why This Model Changes Education
The Hogsback Project's legacy extends far beyond Montana:
Scalability
From writing courses (journal articles) to art classes (data visualization), non-STEM fields join through science communication 1 .
Career Pipeline
78% of participants enter graduate programs—well above the national average 1 .
Global Inspiration
Similar models are emerging in restoration ecology (e.g., South Africa's Forests for Life uses community partnerships for reforestation) .
"I thought I was just counting ants. Suddenly I was a statistician, a geologist, and an ecologist—all before lunch."
Epilogue: The Ripple Effect of Tiny Engineers
The Hogsback Project proves that the best classrooms have no walls. By centering education on a single, dynamic research question—How do small forces reshape worlds?—it transforms students from passive learners into active discoverers. As harvester ants sculpt landscapes, so too do they mold the next generation of scientists: one observation, one dataset, one "aha!" moment at a time. In the end, we're reminded that even the smallest engineers can build giants of human knowledge 1 3 .
