Hurricanes Hit Puerto Rico’s Mangroves Harder Than Florida’s
The scale and pattern of damage to the Puerto Rican forests suggest a complex interplay between wind, land, and sea.
Why Mountainous Upland Forests Emit So Much Methane
New research suggests that moist tree heartwood produces methane and emits the greenhouse gas to the atmosphere.
Can Tree Planting Really Help Mitigate Climate Change?
It depends on where, when, and how.
As Winters Get Warmer, Sugar Maples May Absorb Less Silicon
Rising temperatures that reduce snow cover leave soils vulnerable to frost, reducing silicon uptake by trees, with potential effects on downstream ecosystems.
Can Mangroves Buffer Ocean Acidification?
New research evaluates the ability of coastal foliage to influence the ocean's pH.
Bark Beetles Cause Big Tree Die-Offs, but Streams Flow Steadily
Recent beetle epidemics have driven tree die-offs across North America, and previous studies predicted an increase in annual streamflow would follow—but a new study shows this may not be the case.
