Phenology and Seasonal Ecosystem Productivity in an Amazonian Floodplain Forest

Remote Sensing, 2019
Several studies have explored the linkages between phenology and ecosystem productivity across the Amazon basin. However, few studies have focused on flooded forests, which correspond to c.a. 14% of the basin.

Changing Climate Threatens Irrigation Benefits of Maize Gross Primary Productivity in China

Earth's Future
Intensive irrigation has been proven to profoundly impact climate through the surface energy budget. However, the impacts of irrigation and climate interactions on gross primary productivity (GPP) in maize cultivated areas remain uncertain.

Asymmetric responses of gross primary productivity (GPP) and ecosystem respiration (Reco) in response to long-term drought [PDF]

Geoderma
Gross primary productivity (GPP) and ecosystem respiration (Reco) account for the largest fluxes of CO2 between the land surface and the atmosphere but exhibit different sensitivities in response to climate change causing potentially large effects on land-climate feedback.

Photorespiration as a Thermal Protection Mechanism in Trees: Measurements, Assumptions, and Persistent Gaps

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Conceptual framework linking leaf‐level photorespiratory biochemistry to global‐scale uncertainty in carbon cycle modelling. Rubisco acts as a temperature‐sensitive biochemical switch: At optimal temperatures (~25°C) carboxylation dominates and drives biomass accumulation, whereas heat stress (> 35°C) favours oxygenation and initiates photorespiration (

Multi-scale analysis of urbanization and gross primary productivity during 2000–2018 in Beijing, China

Environmental Research Letters, 2023
Urban vegetation experiences multiple natural and human impacts during urbanization, including land conversion, local environmental factors, and human management, which may bring positive or negative impacts on vegetation gross primary productivity (GPP)

Maize Crops Face High Stomatal Uptake During High Exposure to Ozone in an Agroecosystem in the United States Corn Belt. [PDF]

Glob Chang Biol
Tropospheric ozone (O3) is a phytotoxic air pollutant. The stomatal uptake of O3 is a substantial sink of O3, but it can create oxidative stress within plants, reducing photosynthesis and crop yields. In seasonally dry climates, stomatal regulation causes temporal decoupling between stomatal conductance and atmospheric O3 concentrations protecting ...

Riparian Restoration Improves Physical Habitat but Not Ecosystem Functioning to Reference Levels in Urban Neotropical Streams

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Urbanization modifies stream ecosystems through changes in land use and water quality, with particularly understudied effects in tropical regions. This study evaluates how the conservation status (reference, restored, and impacted) influences nutrient enrichment and organic matter decomposition—key indicators of ecosystem function—across five ...

Using automated machine learning for the upscaling of gross primary productivity

Biogeosciences
. Estimating gross primary productivity (GPP) over space and time is fundamental for understanding the response of the terrestrial biosphere to climate change. Eddy covariance flux towers provide in situ estimates of GPP at the ecosystem scale, but their
