Experimental droughts in mesocosms reveal a gradient of tolerance in Alpine stream macroinvertebrates

open access: yesLimnology and Oceanography, EarlyView.
Abstract Prolonged droughts, driven by climate change and human pressures on water resources, are increasing in frequency and intensity, particularly impacting Alpine rivers. Benthic macroinvertebrates are one of the most important structural and functional components of Alpine lotic ecosystems.

Significant impact of lithogenic dissolution from subantarctic volcanic islands on the regional marine silicon cycle

open access: yesLimnology and Oceanography, EarlyView.
Abstract Silicic acid controls the production of diatoms, a predominant phytoplankton in the Southern Ocean. Diatoms are major contributors to the biological carbon pump, which is particularly active in the Southern Ocean as well as in areas naturally enriched in iron, such as around the Kerguelen Plateau.

Enhanced total carbon in runoff following rewetting of drained boreal and hemi‐boreal wetlands

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Rewetting of drained wetlands is promoted as an efficient nature‐based solution to combat multiple environmental challenges. Yet, how rewetting influences the total lateral carbon export via runoff across diverse landscapes is rarely studied.

Analyzing the Chemical Stability of Bio‐Based Polyamide Resins via Solubility Parameters, NMR Spectroscopy and Capillary Electrophoresis

open access: yesMacromolecular Chemistry and Physics, EarlyView.
The chemical resistance of hot‐melt adhesives is assessed in conditions mimicking mining sites. These polyamide resins are more stable in alkaline than acidic conditions and their mass loss in organic solvents can be predicted with Hansen parameters.

Reversibly Cross‐Linked Polyamide 6 Using 1‐(5‐(Aminoethyl)‐2‐nitrophenyl)Ethanol as Photolabile Cross‐Linker

open access: yesMacromolecular Materials and Engineering, EarlyView.
This exploratory study investigates the reversible cross‐linking of polyamide 6 by the photolabile cross‐linker 1‐(5‐(Aminoethyl)‐2‐nitrophenyl)ethanol (PXL). The storage modulus of the material increases with increasing PXL content and decreases when the exposure time of the samples is increased.

Arctic‐breeding black‐legged kittiwakes show individual variation in foraging responses to glacial conditions without consequences for reproductive output

open access: yesOikos, EarlyView.
Behavioural plasticity is likely to influence how individuals continue to access resources under rapid climate change. Plasticity will be particularly important at highly dynamic, prey‐rich foraging areas such as upwelling fronts of marine‐terminating glaciers in the high Arctic, where profitability varies significantly across space and time ...
