Detecting and modeling topography‐induced differences in plant productivity across a grassland ecosystem gradient

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Understanding spatial variation in grassland productivity is critical for ecological modeling and management. The Great Plains of North America, a vast grassland region east of the Rocky Mountains, exhibits strong gradients in aboveground net primary production (ANPP) linked to precipitation and finer scale topoedaphic variation.

Trends in North American net primary productivity derived from satellite observations, 1982-1998 [PDF]

, 2002
Net primary productivity (NPP) in North America was computed for the years 1982–1998 using the Carnegie‐Ames‐Stanford approach (CASA) carbon cycle model.

Drivers of inter-year variability of plant production and decomposers across contrasting island ecosystems [PDF]

, 2012
Despite the likely importance of inter-year dynamics of plant production and consumer biota for driving community- and ecosystem-level processes, very few studies have explored how and why these dynamics vary across contrasting ecosystems.

Seasonality in Marine Organic Carbon Export and Sequestration Pathways

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The ocean's biological carbon pump transports organic carbon from the surface to depth via three main pathways: the gravitational sinking of particles, active transport by vertically migrating zooplankton, and mixing and advection of suspended and dissolved organic carbon.

Distinct environmental controls on above- and below-ground net primary productivity in Northern China’s grasslands

Ecological Indicators
Grasslands, which cover approximately 40 % of the global land surface, are crucial to the global carbon cycle due to their substantial carbon storage capacity and sensitivity to environmental changes.

Eddy‐Induced Iron Transport Sustains the Biological Productivity in the Gulf of Alaska

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract The surface waters of the subarctic northeastern Pacific Ocean contain high concentrations of macronutrients such as phosphate and nitrate, which can potentially drive photosynthesis and biological uptake of carbon dioxide. Regional biological productivity, however, is limited by a lack of necessary micronutrients such as iron.

MODERATE SEVERITY DISTURBANCE HAS SIMILAR EFFECTS ON THE PRODUCTION OF THREE FORESTS NESTED WITHIN THE UPPER GREAT LAKES LANDSCAPE [PDF]

, 2017
Moderate severity disturbances, which only kill a subset of canopy trees (e.g., via insects, pathogens, and windthrow), are increasingly widespread, and can alter forest structure and production.

<b>ESTIMATION OF NET PRIMARY PRODUCTION (NPP) USING REMOTE SENSING APPROACH AND PLANT PHYSIOLOGICAL MODELING</b><br>(PENDUGAAN NET PRIMARY PRODUCTION (NPP) MENGGUNAKAN PENDEKATAN PENGINDERAAN JAUH DAN MODELING FISIOLOGIS TANAMAN)

Agromet, 2008
<p>Information Net Primary Production (NPP) of tropical forests is important for the development of realistic global carbon budgets and for projecting how these ecosystems will be affected by climate changes. This research utilized remotely sensed data and micrometeorological measurement to provide information on vegetation condition.

Anomalously Low New Production in the Northeast Atlantic During Spring 2024: A Consequence of Weaker Winter Mixing?

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract In 2024 an anomalous region of low chlorophyll water covering ∼721,000 km2 or 1.7% of North Atlantic surface area dominated the Northeast Atlantic. This feature formed during spring, remained identifiable as a region of low chlorophyll throughout the summer months in temperate and subpolar waters and, due to low opal ballasting potential of ...

Continental scale variability in ecosystem processes: Models, data, and the role of disturbance [PDF]

, 1997
Management of ecosystems at large regional or continental scales and determination of the vulnerability of ecosystems to large-scale changes in climate or atmospheric chemistry require understanding how ecosystem processes are governed at large spatial ...
