habitat-structure
Habitat structure refers to the physical arrangement and complexity of a plant's environment, including features like canopy layering, soil texture, terrain, and the spatial distribution of vegetation. It matters for plant science because these structural characteristics shape resource availability—light, water, and nutrients—as well as microclimate conditions, influencing plant growth patterns, competitive interactions, and reproductive success. Understanding habitat structure also helps researchers predict how plant communities respond to environmental change and disturbance.

Scientists deployed cameras at ground, mid-forest, and canopy levels across the Congo Basin and found that studying only the forest floor misses key patterns in how mammals use their habitat. Even small elevation changes shaped which species lived where, but this only became clear when all three vertical layers were analyzed together.
Camera traps deployed at three strata (canopy, understory-midstory, ground) revealed a significant positive effect of elevation on mammal occupancy that was invisible when only ground-level data were used.
A multispecies, multi-scale occupancy model showed that vertical sampling fundamentally altered inferred relationships between mammal communities and environmental gradients.
Even small elevation gradients in lowland tropical forests shaped mammal diversity, likely through soil-mediated effects on habitat structure and resource availability.
