Study Tracks Seasonal Growth and Water Shortage in Trees

HF scientists and students work together to core hemlock saplings.

By Anna Christensen

A paper published this past summer in Tree Physiology finds that tree species of varying wood-porosity experience peak growth at different times of the year, exposing some species to more intense water shortages than others.

The wood-porosity of a tree refers to the structure of its vessels—pipelines within the trunk that carry sap throughout the tree.

Some trees such as

By Anna Christensen

A study just published in PeerJ Life and Environment examines how anthropogenic and natural disturbances from past decades, and even centuries, affect the spatial and species composition of woody plants within a forest plot.

Harvard Forest Senior Ecologist David Orwig and collaborators (Jason Aylward, Hannah Buckley, Bradley Case, and Aaron Ellison) utilized the data from the first

A new study in the Proceedings of the National Academy of Sciences shows that methane emissions in Boston are 6 times higher than previous estimates, and deeply undercounted in state calculations. 

The study, by Harvard Forest research collaborators Lucy HutyraSteve Wofsy and colleagues, used long-term methane data from Harvard Forest as a rural benchmark for analyzing Boston methane data.

A study published today in Functional Ecology by HF Senior Ecologist Audrey Barker Plotkin and colleagues sheds light on why some oak trees in our region survived a recent severe outbreak of invasive moth, and some did not. The key? Carbohydrates.

The new study reveals the specific threshold of reserves necessary for the trees to survive: 1.5 percent carbohydrates
