Air–Water Greenhouse Gases Exchange in Surface Waters of Deception Island (South Shetland Archipelago, Antarctica): Assessment of Drivers of Spatial Variability

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Greenhouse gases (GHGs) such as Carbon Dioxide (CO2), Methane (CH4), and Nitrous Oxide (N2O) play critical roles in global climate change. CO2 dominates due to its high concentration and long atmospheric lifetime, while CH4 and N2O also exert strong heat‐trapping effects despite shorter residence times. Deception Island, in the Southern Ocean,

Identifying hotspots of faunal data deficiency to direct urgent research and monitoring

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Data deficiency is a substantial challenge for extinction risk assessments because incomplete data means we cannot accurately identify priority protected areas for conservation. Here, we use the International Union for Conservation of Nature (IUCN) distributions of amphibians, sharks and rays, fish, mammals, birds, and reptiles to identify ...

Envisioning the work of reconfiguring: A modeling perspective for designing adaptive human‐agent systems

open access: yesAI Magazine, Volume 47, Issue 3, Fall 2026.
Abstract This paper discusses the perspective that managing the configuration of a network of human and software agents is a form of distributed work that should be explicitly considered when designing human‐agent systems. We describe a configuration of human and software agents as the organization of their roles and relationships that shape and ...

Financial Climate‐Risk Measurement, Impact Funds, and Green Transitions

open access: yesJournal of Accounting Research, Volume 64, Issue 4, Page 1867-1903, September 2026.
ABSTRACT Regulators are contemplating or mandating precise measurement of financial climate‐risk exposure to promote sustainable investments. We show that such mandates can be counterproductive in the presence of social funds that catalyze change by subsidizing the adoption of cleaner production technologies.

Kinetic parameter prediction using neural networks identifies limitations to C4 photosynthesis

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1578-1594, August 2026.
Schematic overview of the generation of artificial training data and training of neural networks in C4TUNE. Summary Kinetic models of photosynthesis enable time‐resolved predictions of traits related to this key process and provide the means to identify factors limiting photosynthesis.
