Biomass Nanofiber‐Assembled Superhydrophobic Aerogels with Simultaneously Enhanced Mechanical Strength and Shape Recovery

open access: yesSmall Structures, EarlyView.
This study proposes a hierarchical fabrication strategy for biomass‐derived aerogels. Chitosan and sodium alginate are assembled into nanofibers via ultrasonication, then forming an anisotropic honeycomb‐like microstructure through freeze casting. Methyltrimethoxysilane modification further enhances the aerogel's strength (105.7 kPa at 80% strain) and ...

Nanocellulose Extraction from Biomass Waste: Unlocking Sustainable Pathways for Biomedical Applications

open access: yesThe Chemical Record, EarlyView.
Sustainable extraction methods for converting diverse biomass waste into nanocellulose with remarkable biomedical properties were explored. Optimized pretreatment, mechanical processing, and surface modification techniques that enhanced the functionality of nanocellulose were detailed.

The influence of pre‐exposure to marine heatwaves on the critical thermal maxima (CTmax) of marine foundation species

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Marine foundation species underpin some of the world's most diverse ecosystems but they are increasingly threatened by intensification of marine heatwaves (MHWs). Where MHWs exceed critical thermal maxima (CTmax), increased mortality and population declines can occur ...

Simulated intertidal heat stress on the brown seaweed Ascophyllum nodosum demonstrates differential population sensitivity to future climate

open access: yesJournal of Ecology, EarlyView.
Our findings underscore the importance of replicating realistic tidal cycles and temperature trajectories to accurately assess thermal stress in intertidal species, as temperature fluctuations between high and low tides drive the stress response. Our projections not only align with observed local extinctions but also indicate future trends, emphasising

Stable isotope analysis reveals individual variations in feeding habits among wild Japanese macaques

open access: yesEcological Research, EarlyView.
In this study, we conducted a dietary analysis using stable isotopes on the Japanese macaque (Macaca fuscata) group on Koshima Island, Japan. As a result, we clarified the variation in isotope ratios at the individual level, and indicated that this variation is affected by attributes such as sex or dominance‐subordinate relationships in this group ...
