Technology In Ecology

Banner: Technology in Ecology. Logo with plant in green circle, surrounded by circuit-board lines

The Technology in Ecology Lab collaborates extensively within SERC and globally to design and support technological innovation, serving ecological research, experimental design, and data infrastructure. Ultimately, we aim to utilize open-source technology sensor platforms, like Arduino, to provide low-cost novel methods to monitor environmental phenomena. Using this approach, we develop and support several ongoing climate change experiments, including SMARTX, GENX, and MERIT, and maintain sensor and data infrastructure for the MarineGEO Chemical and Physical Observations Program.

Even modest climate change may lead to major transitions in boreal forests
August 10, 2022
Roy published a paper in Nature on the impacts of warming in southern boreal forests!

“The sensitivity of forests to near-term warming and associated precipitation shifts remains uncertain. Herein, using a 5-year open-air experiment in southern boreal forest, we show divergent responses to modest climate alteration among juveniles of nine co-occurring North American tree species.”

Considering coasts: Adapting terrestrial models to characterize coastal wetland ecosystems
June 15, 2021
Genevieve, Roy, and Pat published modified E3SM models to mimic tidal marsh dynamics and SMARTX findings in Ecological Modeling!

“The Energy Exascale Earth System Model (E3SM) simulates fully coupled processes and interactions among water, energy, carbon and nutrient cycles. E3SM connects vegetation and soil dynamics through nutrient uptake, plant production, litterfall and decomposition as a function of abiotic parameters (e.g. temperature and moisture). However, E3SM is designed to characterize terrestrial ecosystems and connects land and open ocean systems using a single streamflow transport term, ignoring the complex dynamics of energy, water, carbon, and nutrients in coastal systems. The goals of our project were to: (1) Parameterize a point version of E3SM to capture coastal wetland habitats and (2) Determine marsh community responses to increased temperature and elevated CO2.”

Biogeochemical and plant trait mechanisms drive enhanced methane emissions in response to whole-ecosystem warming
April 19, 2021
Genevieve and Pat published findings from SMARTX in Biogeosciences!

“Climate warming perturbs ecosystem carbon (C) cycling, causing both positive and negative feedbacks on greenhouse gas emissions. In 2016, we began a tidal marsh field experiment in two vegetation communities to investigate the mechanisms by which whole-ecosystem warming alters C gain, via plant-driven sequestration in soils, and C loss, primarily via methane (CH4) emissions. Here, we report the results from the first 4 years.”

Synergistic effects of four climate change drivers on terrestrial carbon cycling

Synergistic effects of four climate change drivers on terrestrial carbon cycling
November 23, 2020
Roy published a paper in Nature Geoscience with TeRaCON collaborators!

"Disentangling impacts of multiple global changes on terrestrial carbon cycling is important, both in its own right and because such impacts can dampen or accelerate increases in atmospheric CO2 concentration. Here we report on an eight-year grassland experiment, TeRaCON, in Minnesota, United States, that factorially manipulated four drivers: temperature, rainfall, CO2 and nitrogen deposition.”

Automated methane chambers designed by Roy and Genevieve have become the newest addition to the Global Change Research Wetland! Twelve methane chambers were deployed as a part of GENX to capture methane data at short time scales, including methane changes in response to precipitation, tidal cycles, and other weather events.

GENX

The Greenhouse gas Emissions NeXus experiment is the newest experiment at the Global Change Research Wetland led by Genevieve Noyce. Using an automated methane chamber system, GENX aims to quantify rates of anaerobic decomposition pathways that regulate methane emissions across different time scales. Additional elements like warming, salinity, and inundation will also be incorporated to determine the individual and interactive effects of these variables on methane cycling.

 

TEMPEST

The Terrestrial Ecosystem Manipulation to Probe the Effects of Storm Treatment (TEMPEST) project is run as a partnership between SERC, the Pacific Northwest National Laborator, and the U.S. Department of Energy. The TEMPEST project is monitoring the effects of massive storm events on forest ecosystems, by applying large quantities of salt and fresh water to forest plots. The TE Lab supports the TEMPEST project by helping to maintain the electronic infrastructure deployed in the forest ecosystem.

SMARTX

We support the data infrastructure of the Salt Marsh Accretion Response to Temperature eXperiment which models how future climate predictions will influence salt marshes, by maintaining a network of 6 remote CO2 sensors and warming cables. SMARTX aims to assess plant response to interacting variables (elevated CO2, an increasing temperature gradient above- and below-ground, and changes in inundation frequency) at SERC’s Global Change Research Wetland.

MERIT

The Marsh Ecosystem Response to Increased Temperature is a warming experiment replicating SMARTX infrastructure in collaboration with scientists at the University of Hamburg to measure how salt marshes will be impacted by elevated temperatures in a Northern Sea coastal ecosystem. We support MERIT by implementing Arduino-based technology to create an affordable wireless control network allowing for analyses of plant community responses, successional dynamics, carbon sequestration, and soil accretion.

Carbon in the Capital

Carbon in the Capital is a new CO2 monitoring citizen science project in collaboration with Ph.D. candidate Marc Rosenfield in the Zanne lab at George Washington University. Carbon in the Capital has deployed 33 of our CO2 sensors throughout all 8 Wards of Washington D.C. to monitor changes in emissions during COVID-19 lockdowns. So far, results capture important interplays between transportation emissions and natural signals, which can be significant to mitigating human impacts on the carbon cycle and urban greenhouse gas removal.

TeRaCON

TeRaCON (Temperature, Rainfall, CO2, Nitrogen) is an 8-year-long novel global change experiment in collaboration with Dr. Peter Reich at the University of Minnesota. TeRaCON exposes vegetation in a Minnesotan temperate grassland to manipulated temperatures, rainfall patterns, CO2, and nitrogen to examine the effects of these global change drivers on terrestrial carbon cycling. For TeRaCON, we designed warming infrastructure to manipulate temperature.

We use an Arduino-based data logger platform for our CO2 sensors, which have been deployed throughout Washington, D.C. and in various projects at SERC’s Global Change Research Wetland. Our CO2 sensors feature additional components to measure temperature, humidity, and pressure alongside CO2 measurements, and capture these data every 5 minutes. These robust sensors can capture nonhomogeneous (transitional interfaces, or even patchier environments) landscape dynamics influencing carbon fluxes at a local scale.

Find our 2019 protocol for building our Arduino-based data logger platform here and sensor calibration protocol here.
