Airborne Laser Scanner-Assisted Estimation Of Aboveground Biomass Change In A Temperate Oak–Pine Forest
Skowronski, N. S., Clark, K. L., Gallagher, M., Birdsey, R. A., Hom, J. L.

We estimated aboveground tree biomass and change in aboveground tree biomass using repeated airborne laser scanner (ALS) acquisitions and temporally coincident ground observations of forest biomass, for a relatively undisturbed period (2004–2007; ∆07–04), a contrasting period of disturbance (2007–2009; ∆09–07), …

Contrasting Effects Of Invasive Insects And Fire On Ecosystem Water Use Efficiency
Clark, K. L., Skowronski, N. S., Gallagher, M. R., Renninger, H., Schäfer, K. V. R.

We used eddy covariance and meteorological measurements to estimate net ecosystem exchange of CO2 (NEE), gross ecosystem production (GEP), evapotranspiration (Et), and ecosystem water use efficiency (WUEe; calculated as GEP / Et during dry canopy conditions) in three upland forests …

Modeling Respiration From Snags And Coarse Woody Debris Before And After An Invasive Gypsy Moth Disturbance
Renninger, H. J., Carlo, N., Clark, K. L., Schäfer, K. V.

Although snags and coarse woody debris are a small component of ecosystem respiration, disturbances can significantly increase the mass and respiration from these carbon (C) pools. The objectives of this study were to (1) measure respiration rates of snags and coarse woody debris throughout the year in a forest previously defoliated …

Effects Of Invasive Insects And Fire On Forest Energy Exchange And Evapotranspiration In The New Jersey Pinelands
Clark, K. L., Skowronski, N., Gallagher, M., Renninger, H., Schäfer, K.

We used eddy covariance and meteorological measurements to quantify energy exchange and evapotranspiration (Et) in three representative upland forest stands in the New Jersey Pinelands that were either defoliated by gypsy moth (Lymantria dispar L.) or burned …

Invasive Insects Impact Forest Carbon Dynamics
Clark, K. L., Skowronski, N., Hom, J.

Invasive insects can impact ecosystem functioning by altering carbon, nutrient, and hydrologic cycles. In this study, we used eddy covariance to measure net CO2 exchange with the atmosphere (NEE), and biometric measurements to characterize net ecosystem productivity (NEP) in oak- and pine-dominated forests that were defoliated …

Remotely Sensed Measurements Of Forest Structure And Fuel Loads In The Pinelands Of New Jersey
SKOWRONSKI, N., CLARK, K., NELSON, R., HOM, J., PATTERSON, M.

We used a single-beam, first return profiling LIDAR (Light Detection and Ranging) measurements of canopy height, intensive biometric measurements in plots, and Forest Inventory and Analysis (FIA) data to quantify forest structure and ladder fuels (defined as vertical fuel continuity between the understory and canopy) in the New Jersey …
