Airborne DNA reveals shifting reproductive timing in bryophytes

In the Arctic, mosses and other bryophytes are providing early evidence of ecological shifts linked to warming temperatures. By analyzing environmental DNA preserved on air filters collected over more than three decades in northern Sweden, researchers have reconstructed when these plants released their spores, uncovering evidence that their reproductive calendars are shifting earlier as the climate warms. Bryophytes, plants that lack proper roots or a vascular system to transport nutrients and..
