Three new SPARC Synthesis Groups demonstrate the value of long-term data collected across ecosystems

Posted June 27, 2025

The LTER Network Office is excited to announce that three Scientific Peers Advancing Research Collaborations (SPARC) proposals were funded this year. The three groups will meet in person at the National Center for Ecological Analysis and Synthesis for one week, starting in the fall.

Ten years later: an LTER synthesis working group leads to discovery and accelerates four careers

Posted January 29, 2025

The CoRRE Working Group continues to develop new ways to study plant community change across the globe.

Each spring, the Niwot Ridge snow survey ushers in a new season of fieldwork

Posted September 25, 2023

Snow is the defining control on Niwot’s ecology. Through the winter, the white stuff builds with each passing storm; sometime in the spring, melting begins, flushing water and nutrients through the system. The annual snow survey tracks snowfall through time.

Across fourteen LTERs, soil carbon is a “gatekeeper” on the nitrogen cycle

Posted March 29, 2023

A researcher in an orange vest stands atop a brown and green forest floor with white sampling equipment in front of her and a round puck of soil below her feet.

An LTER cross site synthesis effort reveals that soil carbon availability determines nitrogen mineralization and nitrification rates across a wide diversity of terrestrial ecosystems.

Alpine stream chemistries are changing, but rock glaciers might not have as much influence as previously thought

Posted December 5, 2022

Black mountaintops poke out from a white snowy band in the middle of the frame, and mixed snow and rock extends towards the viewer—this mixed snow and rock is the rock glacier Arikaree.

While glacial thawing shapes ecosystem processes in the Green Lakes Valley, long-term data shows that it alone cannot explain the changing spatiotemporal patterns of stream chemistries.

NEON and LTER: A Long-Term Partnership for Ecological Observation

Posted July 6, 2022

The shared spaces between LTER and NEON add value for both networks and for the research community at large.

Ready-to-teach R Environmental Datasets: the lterdatasampler R package

Posted April 11, 2022

We are excited to share with the broader R community a new collection of 8 data samples geared towards teaching environmental data science!

Stream Dissolved Nitrogen Cycling Responds to Human Activity across the Landscape

A shallow stream runs through red rocks amid a

A new global data synthesis of stream chemistry indicates human activities reduce streams ability to retain and transform nutrients.

Repeat photography engages the public at LTER sites

Posted February 24, 2022

With just a phone camera, anyone can add to a growing dataset tracking environmental change at the Virginia Coast Reserve LTER.

It’s not the plants: nitrogen directly affects alpine soil microbes

Posted December 20, 2021

Can plants dictate how soil microbes respond to nitrogen deposition? New research says no, and sheds light on plant-microbe dynamics.
