A living black spruce branch with short blue-green needles and small dark cones beside scaly bark.

Exhibit 07

Black spruce

Picea mariana (Mill.) Britton, Sterns & Poggenb.

Place

Boreal peatlands and post-fire forest mosaics across northern North America.

Adaptation

Persistent, semiserotinous cones retain seed and release it more quickly after fire, linking reproduction to recurring disturbance.

Molecular Signature

Needle and twig oil analyses identified monoterpenes including alpha-pinene, camphene, and bornyl acetate; proportions shifted with sample preparation.

Scientific Lens

How can volatile-profile analysis retain context about plant tissue and sample preparation?

Human Possibility

What research and design questions might a conifer volatile profile raise for natural-sensory exploration?

Application Fields
