New Study Finds Leaf Surface Water Contributes to Total Canopy Water Content

June 7, 2021

Water availability is essential to terrestrial plants, especially tall canopy trees. Satellite observations at microwave frequencies make it possible to assess total canopy water content and plant stress. However, leaf surface water -- water coming from dew, fog and rainfall -- is often overlooked when interpreting changes in canopy water content. An increasing body of evidence, though, indicates that plants might rely more than originally thought on these nonconventional water sources.

How army ants' iconic mass raids evolved

May 25, 2021

Army ants form some of the largest insect societies on the planet. They are quite famous in popular culture, most notably from a terrifying scene in Indiana Jones. But they are also ecologically important. They live in very large colonies and consume large amounts of arthropods. And because they eat so much of the other animals around them, they are nomadic and must keep moving in order to not run out of food. Due to their nomadic nature and mass consumption of food, they have a huge impact on arthropod populations throughout tropical rainforests floors.

Their mass raids are...

More Species of Trees with Naked Resting Buds than Previously Believed

May 24, 2021

The bud scales of resting buds (buds that form at the end of a growth season which lie dormant until the next growth season) of temperate trees are thought to provide essential winter protection. However naked buds (buds without bud scales) are often considered rare occurrences in temperate climates.

In a study in New Phytologist PhD candidate Kristel Schoonderwoerd (Friedman Lab) and Ned...
