Putting the “urban” in disturbance: Applying ecological frameworks to cities

Posted

The concept of “disturbance” is a core theme of the LTER Network and central to ecological science. How does the idea of disturbance need to change when applied to the interactions of an urban metropolitan region rather than a “natural” system? Ecologists often consider the process of urbanization itself to be a form of disturbance, but that is a habit that has to change, say the authors of a recent paper in Ecosystem Health and Sustainability. People, technology, and infrastructure have to be defined as part of the system when studying cities, they say.

How Will Climate Change Affect Peak Firefly Activity?

Posted

A typical warm summer night is complemented with the familiar glow of fireflies and the light spectacle they create darting around and lighting up the night sky. However, the timing of these light shows might be affected by environmental changes. In order to better understand the life history of the firefly, researchers from the Kellogg Biological Station (KBS) LTER investigated the phenological patterns of fireflies from 2004-2015 to determine what explains the variability observed in their mating season.

Unstable ice. Raging rivers. Fire-scorched landscapes. Deep within Alaska’s Yukon River Basin, residents faced with these obstacles during travel or hunting trips now use camera-enabled GPS units to send photographs to researchers across the state. Scientists at the Bonanza Creek LTER and University of Alaska, Fairbanks are using the images, along with the associated GPS… Read more »

Simulating Climate Change: Take a Walk in a Forest of the Future

Posted

What will the future feel like in our forests? In six plots at the Hubbard Brook Long Term Ecological Research Site in the White Mountains of New Hampshire, the trees already know. Dr. Pamela Templer has created a robust simulation of the climate—warmer summer temperatures and later snowfall—that these forests will experience within the century…. Read more »

ESA By Topic: Presentations on the Ecological Impacts of Saltwater Inundation

Posted

The IPCC projects that, even if humans succeed in keeping temperatures below the 2°C target set in Paris, sea level will rise 0.28 to 0.61 m this century. With this amount of sea level rise, salt water pulses from high tide floods and storm surges will become ever-more common in coastal ecosystems. Multiple LTER sites are running experiments… Read more »

The making of an ice storm

Posted

Ice storms are powerfully disruptive to northeastern forests, but truly understanding their dynamics has proved challenging because they strike with little warning. Hubbard Brook LTER scientists took the matter into their own hands by creating an ice storm of their own making. The experiment, which was covered by NSF360 and Science Now, is allowing them… Read more »

Study: Forest clearcuts show sustained losses of carbon, surprising trends in water

Posted

PETERSHAM, Mass.—A new study out of the Harvard Forest, released today in the journal Global Change Biology, is the first detailed account of how carbon, water, and energy balances shift in the three years following the clearcut of a deciduous forest. The study, conducted by Clark University Professor Christopher Williams and colleagues in a 20-acre… Read more »

In blown down forests, a story of survival

Contact: Clarisse Hart, Harvard Forest Outreach Manager Telephone: (978) 756-6157 (9a to 5p) Email: hart3@fas.harvard.edu October 16, 2012 PETERSHAM, MASSACHUSETTS—In newscasts following intense wind and ice storms, damaged trees stand out: snapped limbs, uprooted trunks, sometimes entire forests blown nearly flat. In the storm’s wake, landowners, municipalities, and state agencies are faced with important financial… Read more »
