Dr. Jennifer Balch, a Fire Ecologist at University of Colorado Boulder, is studying wildfire-impacted areas in the western U.S. to answer burning questions about forest recovery and carbon storage potential. Her work could lead to improved models of the impact of wildfires on atmospheric carbon levels and environmental change.
A new remote monitoring and near real-time alert system is helping NEON scientists rapidly detect and diagnose data anomalies that may indicate a problem with sensors or software.
The Great Lakes Domain (D05) is named for its most recognizable feature: the Great Lakes themselves. At our field sites in Wisconsin and Michigan, we're collecting data representing different management practices in the northern pine and hardwood forests. The data will help researchers understand how land management practices impact both terrestrial and aquatic ecosystems in the Great Lakes region.
An investigation into freshwater diatoms from the NEON aquatic field sites in Puerto Rico led to a reclassification of diatom taxa in the region, and the possible discovery of a new diatom species. A paper recently published in Phytotaxa details the results of the research, which was enabled by samples from the NEON Biorepository.
NEON's 2020 contributions demonstrate the significant impact this data has on ecological science. Here are 10 of the most exciting news items from the NEON program in the past year.
The NEON program is excited to welcome our first cohort of Postdoctoral Fellows! Starting in January 2021, these three early-career scientists will be working in collaboration with NEON staff and the wider user community to leverage NEON data for scientific discovery.
A newly signed MoU reaffirms the long-standing partnerships among six analogous but independent observing networks that monitor the ecosystems that underpin life on Earth, expressly committing to the development of the first-ever Global Ecosystem Research Infrastructure (GERI).
NASA monitors soil moisture levels and freeze/thaw conditions across the globe using a satellite orbiting 426 miles (685 km) above the Earth. To help validate and calibrate these satellite data, NASA relies on direct measurements taken by partners on the ground. Through a new collaboration with Battelle, soil moisture data collected at the National Ecological Observatory Network (NEON) field sites will now be part of those validation efforts.
Looking to predict beetle abundance and springtime greenness, among other things, the NEON Ecological Forecasting Challenge is looking to mobilize researchers and forecast answers to a complex set of ecological questions.
The Great Basin (Domain 15) is also home to the iconic Great Salt Lake, expansive salt flats, and rugged hills and canyons. The NEON program is monitoring changes in the desert ecosystems resulting from warming temperatures, decreased snowpack, and human activity.
How much of the water that enters terrestrial systems is used by plants for growth, and how much simply escapes back into the atmosphere unused? Chris Adkison, a researcher at Texas A&M University, used data from the NEON program to compare the accuracy of different methods of partitioning evaporation and transpiration in a Texas oak woodland.
Battelle is testing applications of DAS technology at a National Ecological Observatory Network (NEON) program ecological field site. The Battelle-led and funded study leverages NEON infrastructure and data analytics expertise from Los Alamos National Laboratory (LANL) to test new applications of a DAS technology.
A new study published in Nature Geoscience uses soil from NEON field sites across the continent to look for insights into how ecosystem variables impact the formation and composition of SOM.
With field sites at the Disney Wilderness Preserve, The Jones Center at Ichauway, and the Ordway-Swisher Biological Station, NEON's Southeast Domain provides a model for collaboration between industry, academia, and large-scale research infrastructures to further ecological and conservation research.
Arbuscular mycorrhizal (AM) fungi are found in nearly every ecosystem, quietly helping plants absorb nutrients from the soil. Dr. Bala Chaudhary wants to build a better model of how these vital ecosystem players disperse across the continent. She is using NEON’s Assignable Assets program to examine the role of aerial dispersal in AM fungal movement.
Dr. Zachary Kayler, an assistant professor in the Department of Soil and Water Systems at the University of Idaho, used NEON soil samples to test the ability of a widely-used soil health metric to detect changes from an extreme weather event - Hurricane Maria - in Puerto Rico.
Can technology fill in the missing pieces when humans can’t get to the field? While there will almost certainly be data gaps for NEON and other large-scale ecological programs this year, automated instrument programs can still provide a lot of ecological insights. In the future, emerging technologies such as drones, smart sensors, and robots could help ecologists collect field data even under challenging circumstances.
The NEON field sites in the Desert Southwest Domain (D14) collect data that can help researchers better understand how the monsoon impacts the ecology of the southwestern deserts and monitor how the monsoon season may be changing over time.
Jeffery Cannon, a Forest Management Scientist at The Jones Center, is using remote sensing data from the NEON program to understand how longleaf pine forests are impacted by and recover from major weather events. He and his colleagues will use the results to develop tools to help forest managers plan restoration and conservation efforts.
From the glaciers of Glacier National Park to the geysers of Yellowstone, the Northern Rockies Domain (D12) is home to some of the most stunning landscapes in the U.S. Sprawling across 290,000 km2 (112,000 square miles) of western Montana, Idaho, and northwestern Wyoming, the Domain boasts more than 20 national parks and forests and millions of acres of protected wilderness.
The NEON program has now made data from its 47 flux towers available through the AmeriFlux data portal. This will allow researchers to synthesize data from the NEON flux towers with data from other towers across the AmeriFlux network.
Andrew Fricker, used remote sensing data from the NEON Airborne Observation Platform to train a neural net to classify tree species in a Sierra Nevada forest. He and his coauthors describe their approach in Remote Sensing: “A Convolutional Neural Network Classifier Identifies Tree Species in Mixed-Conifer Forest from Hyperspectral Imagery.”
Chris Gough, an associate professor of biology at Virginia Commonwealth University (VCU), is using data from the NEON program to explore relationships between forest structure, biodiversity, and other characteristics and their ability to sequester carbon. His collaborative work with PIs from the University of Connecticut and Purdue University was recently published in Ecology: “High Rates of Primary Production in Structurally Complex Forests."
The Ozarks Complex (Domain 08) takes its name from the Ozark Mountains and Plateau, but this diverse Domain contains more than just mountains. Stretching across the southern U.S. from eastern Oklahoma and Texas to western Georgia, D08 supports a variety of ecosystems ranging from upland hardwood forests to coastal floodplains. The NEON program field sites in Alabama provide a window into watershed dynamics in the southeastern U.S.
Understanding why tick populations are increasing, and why some species are spreading into new geographic areas, is of critical importance to public health. In a recent study, researchers used NEON data to develop a model of tick population dynamics at the Ordway Swisher Biological Station field site.
A team led by NEON scientists David Hulslander and Jessica Bolis has developed a method to map tree mortality with an unprecedented level of detail using hyperspectral remote sensing data from the NEON Airborne Observational Platform and a novel imaging algorithm.
The NEON program collects plant phenology data—that is, observations about the timing of biological events—at terrestrial and aquatic field sites across the continent. A partnership with the USA National Phenology Network (USA-NPN) has now made these data available through the USA-NPN data access and visualization tools.
