Dynamic change of calcium-rich compartments during coccolithophore biomineralization

Manuel Guizar Sicairos

Coccolithophores are abundant marine phytoplankton that produce biomineralized calcite scales, called coccoliths, which sequester substantial amounts of carbon and play a substantial role in biogeochemical cycles. However, mechanisms underlying the storage ...

Growth Onset Rather Than Photosynthesis Strongly Regulates Autumn Senescence Termination Besides Climate Change

Charlotte Grossiord

AimPlant senescence largely influences the global carbon cycle by regulating the growing season length. However, the driving mechanisms of plant senescence remain unclear, particularly the role of developmental factors. This study aims to investigate how e ...

Gradients of Deposition and In Situ Production Drive Global Glacier Organic Matter Composition

Tom Ian Battin, Hannes Markus Peter, Matteo Tolosano, Vincent Henri De Staercke, Michail Styllas, Martina Andrea Schön

Runoff from rapidly melting mountain glaciers is a dominant source of riverine organic carbon in many high-latitude and high-elevation regions. Glacier dissolved organic carbon is highly bioavailable, and its composition likely reflects internal (e.g., aut ...

Awakening: Potential Release of Dormant Chemicals from Thawing Permafrost Soils under Climate Change

Ianina Altshuler

Permafrost is a crucial part of the Earth's cryosphere. These millennia-old frozen soils not only are significant carbon reservoirs but also store a variety of chemicals. Accelerated permafrost thaw due to global warming leads to profound consequences such ...

Flood, farms and credit: The role of branch banking in the era of climate change

Seyed Javad Kashizadeh

Using Iran's unexpected flood in April 2019 as a natural experiment, we show that local branches bridge the time gap between the disaster and governmental aids by immediately increasing their lending for two months following the flood. Analyzing proprietar ...

Distinct responses of diatom- and flagellate-dominated Antarctic phytoplankton communities to altered iron and light supply

Christel Sybille Hassler

Primary production in the Southern Ocean is strongly influenced by the availability of light and iron (Fe). To examine the response of two distinct natural Antarctic phytoplankton communities (diatom vs. flagellates) to increasing light and Fe availability ...

Biological and dust aerosols as sources of ice-nucleating particles in the eastern Mediterranean: Source apportionment, atmospheric processing and parameterization

Alexis Berne, Athanasios Nenes, Anne-Claire Marie Billault--Roux, Paraskevi Georgakaki, Kunfeng Gao, Romanos Foskinis

Aerosol-cloud interactions in mixed-phase clouds (MPCs) are one of the most uncertain drivers of the hydrological cycle and climate change. A synergy of in situ, remote-sensing and modelling experiments were used to determine the source of ice-nucleating p ...

On the dynamics of ozone depletion events at Villum Research Station in the High Arctic

Jakob Boyd Pernov

Ozone depletion events (ODEs) occur every spring in the Arctic and have implications for the region's atmospheric oxidizing capacity, radiative balance, and mercury oxidation. Here, we comprehensively analyze ozone, ODEs, and their connection to meteorolog ...

The impacts of rising vapour pressure deficit in natural and managed ecosystems

Charlotte Grossiord

An exponential rise in the atmospheric vapour pressure deficit (VPD) is among the most consequential impacts of climate change in terrestrial ecosystems. Rising VPD has negative and cascading effects on nearly all aspects of plant function including photos ...
