Complementary measurements

with the LI-600 and LI-6800 

Did you know that combining fast survey measurements from the LI-600 Porometer/Fluorometer with detailed data from the LI-6800 Portable Photosynthesis System can enable you to record larger, more informative data sets while saving time? Find out more at our upcoming webinar, “Complementary measurements with the LI-600 and LI-6800.” In the live webinar, Jason Hupp, Sr. Field Application Scientist, will highlight complementary applications of the two instruments and summarize two case studies that highlight the benefits of pairing the LI-600 with the LI-6800.

NEW Extension Manifold:

Redefine your field research

Your long-term soil gas flux research site can now include dozens of chambers distributed over a 2800 square meter footprint—more than 1/4 of a hectare—with the NEW 8250-01 Extension Manifold. Powered by the LI-8250 Multiplexer, each Extension Manifold allows multiple chambers or flasks to share a single LI-8250 port. By extending the maximum number of field site chambers from 8 up to 36, you can ask new research questions and have more confidence in the answers.

Measuring winter methane effluxes from an
American bison herd   

A recent study of a bison grazing system published by EGU’s Biogeosciences presents winter CH4 fluxes measured with the eddy-covariance method. Learn how the American and Swedish research group coupled the eddy covariance data—collected using the LI-7200 and LI-7700 and computed with EddyPro—with a footprint model and a cattle location method to estimate average CH4 fluxes per animal and day.

 Suberin lamellae essential for C4 photosynthesis 

A recent paper in Communication Biology examines C4 photosynthesis in a mutant Setaria viridis with an alteration to the ABCG-type transporter used in the suberin biosynthesis pathway. The mutant plants showed higher CO2 leakage from the bundle-sheath cells, resulting in reduced CO2 assimilation rates compared to the wildtype. The authors—from Australia, India, the Philippines, and the UK—conclude that functional suberin lamellae are an essential anatomical feature for efficient C4 photosynthesis. Learn more about how the group used the LI-6800 Portable Photosynthesis System to measure gas exchange in the wildtype and suberin-deficient plants.

Assessing peatland management in Ireland
with SmartBog  

Many raised bogs in Ireland were altered through the extraction of peat for energy or horticulture but are now the focus of rehabilitation to address the key issues of climate mitigation and biodiversity loss. The SmartBog project in the midlands of Ireland is assessing the management of those peatlands using the LI-COR Smart Chamber and an Eddy Covariance System. Read more about the SmartBog project in an article by Dr. Matthew Saunders of the School of Natural Sciences, Trinity College Dublin.
