Summary: Natural dyes derived from plants, such as the peel of the Parkia roxburghii pod, are soft, eco-friendly, and non-toxic colours that are highly compatible with silk fabric and the environment. This study focuses on optimizing the extraction of dye from the peel for dyeing silk fabric. Various parameters were evaluated, including color strength (K/S) and absorbance of the dye extract, to determine the optimal extraction and dyeing conditions. The use of natural and synthetic mordants resulted in different color patterns, with CuSO4, lime juice, and Terminalia chebula mordants showing better wash and light fastness in meta-mordant conditions.

Summary: Moringa oleifera seeds can be used for water and wastewater treatment due to their cationic proteins and high oil content. This study investigated the effects of oil extraction on the seed structure, composition, and coagulant activity, highlighting the potential value of seed waste. The extracted oil and seed waste can be used together as a more affordable, sustainable, and natural alternative for oil and grease removal from wastewater. Further research is needed to optimize the performance of seed-derived flocculants at specific pH values.

Summary: In this research, the improvement in colorfastness of a yellow natural pigment derived from Coral Jasmine using eco-friendly shade developers and microwave radiation was investigated. The study found that adding 35 mL of yellow water extract to wool, treated with microwave radiation and salt, resulted in a high color yield. The addition of tannic acid, orange peel, acacia, and pomegranate extract before and after dyeing also produced colorfast shades. These findings suggest that the combination of eco-friendly mordants and microwave radiation enhances the dyeing behavior of Nyctanthes Arbortristis wool, making the process more sustainable and valuable.

Summary: Increasing environmental awareness has led to a growing interest in natural dyes in the textile dyeing industry. However, the performance of natural dyes is generally inferior to synthetic dyes. This study explored the potential use of soy protein as a bio-mordant and sonochemical-assisted dyeing for cotton fabric with natural dye from Syzygium cumini fruits. The results showed that the sonochemical-assisted dyeing significantly increased dye absorption and color values compared to conventional dyeing methods.

Summary: Fuel moisture content is a crucial factor for forest fires worldwide, however, its dynamics and determinants in forest canopies remain poorly understood. This study integrated a FMC module into the SurEau-Ecos model to predict leaf live fuel moisture content and canopy fuel moisture content based on leaf water potential. The results showed that drought-induced foliage mortality is expected to increase as the climate gets drier.

Summary: The Cretaceous-Cenozoic expansion of tropical forests created canopy space for diverse epiphytic communities, including Eupolypod ferns. Eupolypods proliferated in this niche, and the transition to the canopy was associated with reduced xylem content and smaller tracheid diameters. However, no differences were found in species vulnerability to embolism and pit membrane thickness. In Eupolypod epiphytes, traits associated with water conservation, such as thicker leaves and lower stomatal density, favored water retention and may have contributed to the radiation in the canopy.

Summary: Forests and vegetation in many parts of the world face water limitations and plants need to avoid hydraulic failure. However, plants take hydraulic risks by operating at water potentials that partially damage their water conduits. This article introduces an eco-evolutionary optimality principle for xylem conduit design which explains this phenomenon based on the idea that conductive efficiency and safety are optimally adapted to the environment. The model explains the relationship between tolerance to negative water potential (psi(50)) and the minimum psi (psi(min)) across different species and within individuals of two species.

Summary: This review article introduces the presence of unique nanobubbles in the xylem of plants and discusses how the polar lipids coating them enable their persistence in a dynamic environment with negative pressure, large pressure fluctuations, and wide temperature fluctuations. The theoretical considerations about the formation of lipid-coated nanobubbles from gas-filled spaces in the xylem and the role of mesoporous fibrous pit membranes in creating the bubbles are also discussed.

Summary: Studying the impacts of past climate change on biodiversity helps to understand the risks from future climate change. This study found that larger glacial-interglacial temperature change was associated with lower species replacements and higher richness changes in beta-diversity. Furthermore, regions with large temperature change showed lower phylogenetic and functional turnover and higher nestedness than expected, indicating selective processes during glacial-interglacial oscillations. These findings suggest that future human-driven climate change could lead to local homogenization and reduction in angiosperm tree diversity.

Summary: Biodiversity shortfalls occur due to uneven sampling in time and space, as well as human bias towards certain species. These knowledge gaps can hinder the understanding of the relationship between biodiversity and ecosystem services, impacting conservation and restoration efforts. In this study, we investigated the drivers of trait data gaps in the Atlantic Forest biodiversity hotspot, focusing on plant functional traits and their association with range size and economic use. Our findings suggest that species with smaller ranges and no economic use have larger trait gaps. Geographically, locations with more species of economic use show lower trait gaps, especially in the eastern Atlantic Forest. This research highlights the need to prioritize sampling efforts for functional traits in certain species and areas to advance conservation and restoration in the Atlantic Forest.

Summary: Intervessel pits serve as valves to prevent embolism and optimize transport in xylem. The trade-off between safety and efficiency in hydraulic transport is non-linear, with the intervessel pit area and membrane thickness playing crucial roles, and this trade-off can be adjusted depending on environmental conditions.

Summary: The increasing frequency of global change-type droughts has created a need for fast, accurate and widely applicable techniques for estimating xylem embolism resistance to improve forecasts of future forest changes. This study compared two rapid methods for constructing xylem vulnerability curves and evaluated their agreement and sensitivity to measurement duration. The results highlight the value of the Pneumatron as an easy and reliable tool to estimate embolism thresholds for a wide range of temperate angiosperms.

Summary: This study investigates the correlation between the relative vessel area of xylem and the resistance to embolism in different species from the genera Acer, Cinnamomum, Ilex, Quercus, and Persea. The results show that a low vessel lumen fraction (VLF) increases the resistance to gas movement and reduces the likelihood of embolism propagation, while a high VLF enhances gas transport and connectivity between conduits. Gas movement rate due to local pressure differences and xylem network connectivity is identified as a central driver of embolism propagation in angiosperm vessels.
