SIMULATING OZONE EFFECTS ON FOREST PRODUCTIVITY: INTERACTIONS AMONG LEAF‐, CANOPY‐, AND STAND‐LEVEL PROCESSES [PDF]

, 1997
Ozone pollution in the lower atmosphere is known to have adverse effects on forest vegetation, but the degree to which mature forests are impacted has been very difficult to assess directly.

Explaining Bird Richness With 30‐m Resolution Dynamic Habitat Indices Derived From Landsat Satellite Data Across the Conterminous US

Journal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim Biodiversity is declining at a rapid rate, and effective conservation necessitates understanding the drivers of species richness patterns at management‐relevant scales. Vegetation productivity data derived from satellite data estimate the available energy in ecosystems, allowing the generation of relevant indices that explain biodiversity ...

Understanding Muroidea (Rodentia) Species Richness: The Complementary Roles of Adaptive and Non‐Adaptive Diversification

Journal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim To evaluate environmental drivers of species richness in the Muroidea superfamily and to determine the relative contributions of adaptive and non‐adaptive diversification using organismal or emergent properties, trait variation. Location Global. Time Period 32 million years ago to the present.

Biological Productivity of Oligotrophic and Eutrophic Mires in the Southern Taiga of Western Siberia [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2009
The results of long-term (1999-2007) investigations of Phytomass (above and below-ground living biomass), dynamics of phytomass and mortmass and net primary productivity of oligotrophic and eutrophic mire in southern taiga in Western Siberia (Tomskaya ...

Physical and Ecological Forcings Drive the Particle Dynamics and Enhanced Carbon Export Efficiency in the Tropical Marginal Sea

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Marginal seas contribute disproportionately to the ocean carbon cycle but remain poorly constrained due to strong spatial and seasonal variability. Here, we combine newly collected in situ particle imagery with machine learning to reconstruct monthly, depth‐resolved climatologies of particle biovolume and size distribution in the South China ...

Bacteria as Passive Passengers in the Equatorial Pacific Biological Carbon Pump

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Bacteria are important agents modulating the efficiency of the ocean's biological carbon pump (BCP). The long‐standing view considers bacteria as degraders of sinking particulate organic carbon (POC), yet underappreciates their contribution to carbon export.

Spatio-Temporal Changes of Vegetation Net Primary Productivity and Its Driving Factors on the Tibetan Plateau from 1979 to 2018

Atmosphere
The Net Primary Productivity (NPP) of the Tibetan Plateau (TP) has undergone significant changes since the 1980s. The investigation of the spatiotemporal changes of NPP and its driving factors is of significant importance.

Carbon dynamics, net primary productivity (NPP) and human appropriated NPP (HANPP) across a forest‐cocoa farm landscape in West Africa [PDF]

, 2019
Terrestrial net primary productivity (NPP) is an important metric of ecosystem functioning; however, there is little empirical data on the NPP of human-modified ecosystems, particularly smallholder,perennial crops like cocoa (Theobroma cacao), which are extensive across the tropics.

Assessing Consistency in Fuel Consumed Between Activity‐Based Wildfire Emission Estimates

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Wildfire emission inventories exhibit large variability that complicates assessments of smoke impacts. Here we compare fuel consumed (in mass per burned area units) from multiple burn area‐based and energy‐based approaches for fires in the western US during 2020. Average fuel consumed can vary by up to factors of 2–16 between approaches across

Analysis of the Characteristics and Mechanism of Spatial and Temporal Changes in Net Primary Productivity (NPP) in Northwest Liaoning Province

Applied Sciences
This study used Theil–Sen median trend analysis and Mann–Kendall test, which are more suitable for long-term series research, to analyze high-precision NPP data and investigate the spatiotemporal characteristics of NPP (net primary productivity) in northwest Liaoning from 2001 to 2021.
