• Call for Working Group Proposals

    To promote analysis and synthesis of LTER data, the NCO requests proposals for Synthesis Working Groups, with research to begin before May 2017. Funding is available for 2-4 projects of up to 2 years in duration.

  • ESA By Topic: Presentations on Carbon Cycling

    Of the approximately 400 Gigatonnes of carbon released into the atmosphere over the past 200 years, only half has remained in the atmosphere. The other half has been absorbed by the earth’s natural carbon sinks— global oceans, soils, and plants— slowing the amount of climate change we might otherwise observe.

  • ESA BY Topic: Presentations on Soil Ecology

    The United Nations estimates that 33% of global soils are moderately to severely degraded, and that given average rates of erosion, topsoil could be gone in 60 years. In response, the UN General Assembly declared 2015 the International Year of Soils.

  • ESA By Topic: Presentations on Urban Ecology

    Global population continues to grow: the United Nations expects an additional 2.5 billion people by 2050, all of whom will be absorbed into urban areas. When demographers add rural to urban migrants to that number, they project an additional 3.1 billion city dwellers by mid-century.

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

    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.  

  • ESA By Topic: Presentations on the Ecological Impacts of Saltwater Intrusion

    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.

  • LTER Presentations at 2016 ESA Annual Meeting

    From August 7 to August 12, the Ecological Society of America will hold its annual meeting in Fort Lauderdale, Florida. This year’s theme, “Novel Ecosystems in the Anthropocene,” will build on discussions initiated during last year’s centennial meeting, “Ecological Science at the Frontier.”

  • PhysFest: the "Un-Meeting"

    PhysFest participants measure gas exchange on an

  • Distributed Graduate Seminar on Ecological Theory and Long Term Research

    Following on the Ecological Theory working group at the 2015 LTER All Scientists Meeting, Evelyn Gaiser and John Kominoski have developed a syllabus for a distributed graduate seminar. The seminar series will engage scientists from key theoretical fields of ecology to speak about how long term research informs the evolution of that theory.

  • 2016 LTER Synthesis Working Groups Selected

    One strength of the Long Term Ecological Research (LTER) Network is that it reveals patterns and connections that are only apparent over years and decades. As a national network, it also offers extraordinary opportunities to make comparisons among ecosystems. The Network Communications Office announces the funding of three LTER synthesis proposals, which combine existing data to yield fresh insights into how ecological systems work. 

  • Headwaters to Oceans: ASLO Special Issue

    Manuscripts due November 7, 2016

  • Building International Connections

    The International LTER Network is holding its first global open science meeting in Kruger National Park, South Africa. Recognizing the value of this event for building international scientific collaboration, inspiring fresh ideas, and expanding the Network’s reach, NSF provided a supplement to help support attendance of some LTER scientists at this landmark meeting.

  • 40 Year-Old Samples Confirm a Modern Hypothesis

    Hubbard Brook LTER investigator Myron Mitchell talks with Living on Earth's Steve Curwood about how isotope data from Hubbard Brook's 40 year history of streamwater samples helped confirm the hypothesis that the source of precipitation in the northeastern U.S. has been changing as the arctic has been melting.

  • Coral Reef Resilience: The Importance of Fish Functional Groups

    In 2008, Xueying “Shirley” Han had just started her first field season as a PhD candidate at the Moorea Coral Reef Long-Term Ecological Research Site in French Polynesia when an outbreak of crown-of-thorns seastar (Acanthaster planci) decimated the coral in the fore reef, the seaward slope of the reef where the largest and most diverse corals tend to thrive. In 2010, when Cyclone Oli hit the reef, Han wondered which way the scale would tip: could the coral recover from both these impacts? Or would macroalgae move in and dominate?

  • Rot: The Afterlife of Trees

    Sometimes, it helps to remember that trees are more than nitrogen, carbon, biomass, productivity. For artists participating in the multimedia exhibit "Rot: The Afterlife of Trees" at the Corvallis Arts Center, they are inspiration.

  • Science Policy Forum: Liberating Data (and Samples)

    A phalanx of open-science advocates (including Harvard Forest LTER's Aaaron Elison) recently published a Science Policy Forum full of broad principles and specific proposals on how the scientific community might cultivate a more open, transparent, and collaborative approach to data archiving and sharing. And they didn't give anybody a pass on physical samples either.

  • Integrative Model Supports Biodiversity-Productivity Link

    For nearly half a century, ecologists have struggled to explain the relationship between ecosystem productivity and species richness. In a recent paper in Nature, USGS Ecologist James Grace and colleagues have managed to account for the many variables and confirm the long-suspected connection.

  • ILTER Open Science Meeting: Abstract Deadline March 15

    The International LTER Network is pleased to announce its first global Open Science Meeting to be held from 9-13 October 2016 in the Kruger National Park, South Africa. Registration will be open to all experts involved in LTER, interested researchers, and stakeholders. The deadline for abstracts is March 15, 2016.

  • The making of an ice storm

    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 to compare before and after conditions and take measurements on replicate plots, each the size of football fields.
