This project aims to extend current macrosystem biological understanding to include throughfall (TF) and stemflow (SF) particulate concentrations, fluxes and composition, specifically addressing 3 major objectives: (1) estimate the net rainfall water and particulate mass flux across forest types; (2) characterize the particulate composition of TF and SF; and (3) identify major drivers of macrosystem variability in net rainfall particulate flux and composition.
In conjunction with NEON Small Mammal Sampling, iButtons are deployed at one pathogen grid at each selected site over three field seasons and are associated with captures during mammal processing. Tissue samples are collected from Peromyscus sp. captured on the same grid in support of this project.
This RAPID project deployed a NEON MDP coupled with high-performance computing resources from the NSF-funded SAGE project to enable responsive and real-time, fire monitoring, development of early smoke detection algorithms, and data-driven soil sample collection immediately following fire activity.
NEON provides support with installation, maintenance, and annual sampling of three passive MWAC dust collectors at each of the 20 NEON terrestrial core sites.
Examine the patterns of distribution and reproduction of macrofungi (mushrooms) across the United States.
Examine Solar Induced Fluorescence (SIF) along with visible to near infrared reflectance in high latitude ecosystems using a FLoX (Fluorescence Box, JB Hyperspectral) mounted on the flux tower. In addition to measurements of leaf level electron transport rate (ETR) and non-photochemical quenching (NPQ) from a MoniPAM Fluorometer.
Evaluate the relationships between photosynthetic carbon uptake/GPP, tree radial growth, hydration, and environmental variables at sub-seasonal timescales
Link spectral measurements from existing PhotoSpec spectrometer and pigment measurements (which we are doing at 10 trees at DEJU) over the next several years with newly installed point dendrometer measurements.
Study of continental-scale spatial and temporal patterns in fine particle composition and function that are transported through wadeable streams and larger river networks.
