Contrasting functional responses of benthic and hyporheic stream biofilms to light availability and macronutrient stoichiometry

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nutrient dynamics in headwater streams are governed by benthic and hyporheic biofilms, with carbon (C) : nitrogen (N) : phosphorus (P) ratios driving the heterotrophic microbial biofilm development through nutrient limitation. Furthermore, heterotrophic responses to changes in C : N : P ratios are probably modulated by autotrophic responses to

The ICOS OTC pCO2 instrument intercomparison

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract In 2021, the Ocean Thematic Centre of the European Research Infrastructure “Integrated Carbon Observation System” conducted an international partial pressure of carbon dioxide (pCO2) instrument intercomparison. The goal was to understand how different types of instrumentation for the measurement of ocean pCO2 compare to each other.

Fiber Reinforcement of Soft Spider Silk Hydrogels

open access: yesMacromolecular Rapid Communications, EarlyView.
Along the development of matrices for biomedical applications, precise tuning of the biomaterial to interact with specific cell types/tissues is essential. The fabrication of fiber mesh‐reinforced soft hydrogels made of recombinant spider silk proteins allows for the adjustment of mechanical properties and hydrogel porosity, leading to improved cell ...
