You'll start with a tree-ring sample from a living tree and, using other samples, piece together a pattern of rings that stretches back through time.

Mercury concentrations in fig trees could provide useful information about mining activity in the rainforest over time ...

The tree ring samples were gathered from 13 sites around the intersection of the Chic-Choc and McGerrigle ranges, in areas that have never been clearcut by the forestry industry.

Tree studies establish unbroken climate timelines by comparing ring patterns to consecutively older and older samples, matching them up like bar codes. A 2022 study used tree rings to reconstruct ...

As the climate warms, drought conditions are intensifying in many parts of the world. The effects of hydrological drought on ...

This Douglas-fir sample from the Southwest has annual tree rings dating back to the year 1527. The narrowing of the rings that formed from the 1560s through the 1590s indicates that the tree grew ...

Mercury pollution in the Amazon is caused by gold mining. Discover how tree core samples identify the concentration and ...

Due to the equitable year-round climate in the neotropics, not all trees form rings, and of the examined species, only F. insipida exhibited them. Tree core samples were collected at two sites far ...

The researchers created a tree ring record from samples gathered in the mountains, providing data dating back to 1822. This extends the historical knowledge well past the records established from ...
