Comparing sap flow calculations from Heat Field Deformation (HFD) and Linear Heat Balance (LHB) methods
Zhao, Junbin; Lange, Holger; Meissner, Helge Rainer; Bright, Ryan M. (Peer reviewed; Journal article, 2022-06-15)Heat Field Deformation (HFD) is a widely used method to measure sap flow of trees based on empirical relationships between heat transfer within tree stems and the sap flow rates. As an alternative, the Linear Heat Balance ... -
Estimating Carbon Sink Strength of Norway Spruce Forests Using Machine Learning
Zhao, Junbin; Lange, Holger; Meissner, Helge Rainer (Peer reviewed; Journal article, 2022-10-19)Forests sequester atmospheric carbon dioxide (CO2) which is important for climate mitigation. Net ecosystem production (NEP) varies significantly across forests in different regions depending on the dominant tree species, ... -
Freshwater wetland plants respond nonlinearly to inundation over a sustained period
Zhao, Junbin; Malone, Sparkle L.; Staudhammer, Christina L.; Starr, Gregory; Hartmann, Henrik; Oberbauer, Steven. F. (Peer reviewed; Journal article, 2021-10-07)Premise Wetland plants regularly experience physiological stresses resulting from inundation; however, plant responses to the interacting effects of water level and inundation duration are not fully understood. Methods We ... -
Gap-filling continuously-measured soil respiration data: A highlight of time-series-based methods
Zhao, Junbin; Lange, Holger; Meissner, Helge Rainer (Peer reviewed; Journal article, 2020-05-15)Soil respiration is an important ecosystem process that releases carbon dioxide into the atmosphere. While soil respiration can be measured continuously at high temporal resolutions, gaps in the dataset are inevitable, ... -
Integrating aquatic metabolism and net ecosystem CO2 balance in short- and long-hydroperiod subtropical freshwater wetlands
Malone, Sparkle L.; Zhao, Junbin; Kominoski, John S.; Starr, Gregory; Staudhammer, Christina L.; Olivas, Paulo C.; Cummings, Justin C.; Oberbauer, Steven F. (Peer reviewed; Journal article, 2021-07-29)How aquatic primary productivity influences the carbon (C) sequestering capacity of wetlands is uncertain. We evaluated the magnitude and variability in aquatic C dynamics and compared them to net ecosystem CO2 exchange ... -
Klimatiltak for å redusere klimagassutslipp fra drenert organisk jordbruksjord
Weldon, Simon; Fadnes, Kjetil Damsberg; Kvifte, Åsmund Mikalsen; Hobrak, Katharina Therese; Takriti, Mounir; Zhao, Junbin (NIBIO Rapport, Research report, 2024)Rapporten er utarbeidet på oppdrag for Miljødirektoratet. Den gir en oversikt over kunnskapsgrunnlag for mulige tiltak for å redusere utslipp av klimagasser fra drenert organisk jordbruksjord i Norge, både ved restaurering ...
