The longer, warmer days of spring spark phenological changes in trees, from root to tip. As their limbs stretch and twist ...

Tree samples Griffin and his team bring back to the lab display little growth due to the drought, now in its 22nd year. The rings also indicate that today’s droughts stand out compared to those ...

It breaks off branches and scrapes bark. But it also affects inside the tree. The growth rings become slightly irregular and warped. Often scientists have studied regions where avalanches are ...

These eruptions likely cast a volcanic winter over the northern hemisphere, impacting the trees at Mount Iškoras in Norway, where the study was conducted. "Blue rings look like unfinished growth ...

the tree will bend upwards as it grows to right itself, and that growth pattern will show up in its rings. The stress of the avalanche can also cause slow growth, resulting in narrow rings.

found in tree growth rings, according to the statement. Carbon-14 is a naturally occurring radioactive variant of carbon, it forms in the atmosphere when cosmic radiation interacts with nitrogen.

Our study delved into this using dendrochronology, the analysis of tree growth rings, to explore relationships between flooding, climate variables, and site-specific conditions. Dendrochronology ...

Steve Nix is a member of the Society of American Foresters and a former forest resources analyst for the state of Alabama. The most accurate way foresters determine the age of a tree is by ...
