Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus

open access: yesNew Phytologist, EarlyView.
Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...

Greater Resistance to Drought‐Induced Embolism Is Linked to Higher Yield Maintenance in Soybean

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT With increasing drought events worldwide, crop breeding must focus on drought resistance to maintain crop yields. To ensure a high level of gas exchange and growth, plants need to maintain the integrity of their vascular system under drought conditions. While the impact of drought‐induced vascular damage on tree species is well‐documented, its

Measurement and modeling of diffuse ultraviolet radiation: A review

open access: yesPhotochemistry and Photobiology, EarlyView.
Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.

Expert opinions regarding the concept of blue carbon in seaweed systems

open access: yesPhycological Research, EarlyView.
SUMMARY A collection of expert opinions critically evaluates the role of seaweed in blue carbon strategies for climate change mitigation. While the concept of fast‐growing seaweed to capture atmospheric carbon is appealing, the experts largely agree that its potential for direct, long‐term carbon sequestration is currently overstated and faces ...

Sedimentary biogeochemical provinces in the northern limit of the oxygen minimum zone from the northeastern Mexican Pacific

open access: yesSedimentology, EarlyView.
ABSTRACT Continental margins are reservoirs of materials of terrestrial and marine origin, and they play a crucial role in understanding the spatial and temporal variability of biogeochemical cycles. This, in turn, provides insights into the development and intensity of oxygen minimum zones (OMZs).

Diverse Responses of Upper Ocean Temperatures to Chlorophyll‐Induced Solar Absorption Across Different Coastal Upwelling Regions

open access: yesGeophysical Research Letters
Chlorophyll in phytoplankton absorbs solar radiation (SR) and affects the thermal structure and dynamics within upwelling regions. However, research on this process across global‐scale coastal upwelling systems is still lacking.

Chamber‐by‐Chamber Measurements of Planktonic Foraminiferal Mg, Sr, and Na to Ca Ratios With Femtosecond LA‐ICP‐MS

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.
ABSTRACT Rationale Distribution patterns of foraminifera are controlled by environmental parameters such as temperature, salinity, and nutrient concentrations in each water mass. Since trace elements to Ca ratios of marine microfossil calcite test of foraminifera record environmental and ecological habitat information, we used femtosecond (fs) LA‐ICP ...
