Warmer winters have diverse effects on tree growth

Every step of a tree’s growth is on a strict time-table, from the first emergence of life sprouting up through the soil to the formation of vast green canopies that block out almost all of the sun’s light. These growth cycles (budding leaves, flowering, etc.) are controlled by various environmental factors that act as cues… Read more »

Microbes respond quickly to fluctuating salt marsh conditions

The ebb and flow of the tide through coastal salt marshes brings wide swings in temperature, salinity, oxygen levels and pH. Many of these fluctuations occur at short timescales (e.g. multiple times per day) and have a profound impact on both the types of microorganisms that can exist in such a dynamic environment, and how… Read more »

A tale of two forests: exploring forest management in the Pacific Northwest

“Social forestry” describes the hybrid system of bottom-up grassroots oversight by local stakeholders and top-down, science-informed policy from larger governing bodies to determine forest management practices. Social scientists from the University of Freiburg in Germany and the University of Oregon analyzed the implementation of social forestry through a comparative case study of two National Forests… Read more »

Using Drones to Understand the Timing of Fall and Spring

As this winter continues to bring freezing temperatures and intense “bomb cyclone” snow storms to the eastern U.S., many are wondering: “When, exactly, will spring arrive?” Researchers with the Harvard Forest LTER were wondering the same thing as they conducted a study using drones to track timing of phenological events in a mixed forest ecosystem… Read more »

Water is key to tropical forest carbon storage

rainforest

Tropical forests are sometimes referred to as the “lungs of the planet,” and for good reason – the high plant biomass of tropical regions produces a large portion of the oxygen we breathe and absorbs significant amounts of carbon dioxide. Rainfall, nutrient availability, and amount of disturbance (natural or human) a forest experiences can all… Read more »
