Habitat protection and removal of encroaching shrubs support the recovery of biodiversity and ecosystem functioning

AbstractLivestock overgrazing causes environmental degradation, species invasion, biodiversity loss, and productivity decline, with profound consequences for ecological sustainability and human livelihoods. Habitat protection can mitigate such impacts, but we know little about how the long‐term recovery of plant communities from livestock overgrazing depends on the presence of encroaching shrubs. Here, we explored how shrub encroachment mediates the effects of habitat protection (i.e., livestock exclusion and creation of UNESCO protected areas) on biodiversity recovery and ecosystem functioning (i.e., biomass productivity). We leveraged a long‐term (15–25 years) experiment of livestock exclusion and complemented it with the removal of an encroaching shrub species in pasture areas and protected areas. We reveal that habitat protection has positive effects on patterns of recovery. Yet, the effects of habitat protection are mediated by shrub encroachment. Encroaching shrubs have net positive effects on plant diversity in pasture areas but inhibit biodiversity recovery in protected areas. The combination of habitat protection and the removal of encroaching shrubs best enhances the recovery of plant diversity and biomass productivity. A potential underlying mechanism is the shift in plant interactions from facilitation for recruitment and associated resistance to competition for water. Understanding species interactions is key to guiding conservation and restoration actions which can turn degraded ecosystems back into functional, species‐rich communities.

Cocoa agroforestry in Brazil through a public-private partnership

Historically, Brazil was a significant cocoa producer, primarily in the Amazon region, but since the 1970s, cocoa production became increasingly replaced by extensive livestock farming. What production remained, was halted by a fungal epidemic, resulting in Brazil becoming a net importer of cocoa beans. Thanks to recent sustainable development programmes and the emergence of the bioeconomy, Brazil has since experienced renewed interest in cocoa cultivation, especially in cocoa agroforestry. Initiatives such as Mondelez's Sustainable Cocoa Production project aim to promote sustainable cocoa production, with a focus on environmental regulations and good agricultural practices. The project focuses on two regions, Bahia and Pará. In Bahia, efforts are directed towards rejuvenating cocoa crops in cabruca systems, a traditional agroforestry system where cocoa is cultivated beneath native tree canopies. Small-scale farmers received training and experimental plots demonstrated that proper management practices could control fungal disease and increase cocoa production significantly, generating increased income. In Pará, cocoa agroforestry systems are promoted as an alternative to cattle ranching, which destroyed forests to create, now degraded, pasturelands. While restoration efforts are challenging, agroforestry systems showed promising financial returns compared to cattle ranching. Local farmer organisations also benefitted from workshops and ongoing mentoring regarding their management and business capacities. A failure of the project was that in some instances, agroforestry systems were promoted more as a way to produce cocoa than as an opportunity to diversify, which must be the priority. New due diligence initiatives in Europe have also highlighted the importance of traceability and sustainability in cocoa production, posing new challenges for Brazil’s small-scale farmers. The cocoa agroforestry systems in Bahia and Pará have, nonetheless, shown potential for sustainable local development in Brazil. To ensure their success and sustainability in the long term, there must be continued support systems for farmers and value must be ascribed to the immense product diversity of cocoa agroforestry.

Effects of Sugarcane-Derived Polyphenol Supplementation on Methane Production and Rumen Microbial Diversity of Second-Cross Lambs.

The objective of this study was to evaluate the effects of feeding sugarcane-derived polyphenolic supplement (Polygain, The Product Makers Australia, Keysborough, VIC, Australia) on enteric methane (CH4) emission, rumen microbiota, and performance of second-cross lambs. For this purpose, 24 Poll Dorset × (Border Leicester × Merino) lambs were allocated to 3 different treatments: Control (C), 0.25% Polygain (0.25 PG), and 1% Polygain (1 PG) diets with a uniform basal feed (25% cracked wheat grain, 25% cracked barley grain, 25% oaten chaff, 25% lucerne chaff). Both doses of Polygain reduced the total CH4 production (g/day; p = 0.006), CH4 yield (CH4, g/kg of dry matter intake; p = 0.003) and CH4 intensity (CH4, g/kg of BW; p = 0.003). Dry matter intake tended to be greater (p = 0.08) in sheep fed 1 PG compared to the C group, with the 0.25 PG group being intermediate. The average daily gain of the lambs was improved (p = 0.03) with 1% Polygain supplementation. The relative abundance of genera Methanobrevibacter_unidentified, Methanomethylophilaceae_uncultured, Methanogenic archaeon mixed culture ISO4-G1, Methanosphaera uncultured rumen methanogen, Methanogenic archaeon ISO4-H5, and Methanobrevibacter boviskoreani JH1 were reduced with Polygain supplementation. In conclusion, feeding Polygain reduced lambs' enteric CH4 emissions, altered the rumen microbiome, and improved the growth performance of lambs.

Guidelines for assistive technology service provision – A scoping review

Purpose: Despite the high unmet need for effective AT provision, multiple service delivery models across different countries, and a shortage of personnel trained in this field, no widely useable and accepted Assistive Technology (AT) service provision guidelines currently exist. This review aims to provide an overview of the literature regarding AT service provision guidelines to inform the development of globally useable AT provision guidance, aligned with contemporary global initiatives to improve access to AT. Materials and Methods: The rapid scoping review method used a two-tiered approach to identifying relevant publications: (1) systematic search of academic databases (Medline, CINAHL, SCOPUS, and Google Scholar); (2) consultation with international AT organisations and experts. The search was conducted in March 2023 with no date limitations. Analysis was guided by the TIDE-funded HEART research on quality AT provision and service delivery processes in Europe, as well as the WHO-GATE 5 P framework for strengthening access to AT. Results: 35 publications were identified from various countries, and directed at differing assistive products, personnel, and provision contexts. No established guidelines for AT service provision currently exist. However, despite the variety in contexts, the range of assistive products and the range of stakeholders to whom guidelines are directed, several key service delivery steps were identified that may form part of such guidelines. Conclusions: This review offers a strong starting point for developing guidance for AT provision to meet global needs. Careful consideration of vocabulary, process, and application to the diversity of assistive products is recommended in systematizing globally applicable guidance.

Decoding the chemical language of Suillus fungi: genome mining and untargeted metabolomics uncover terpene chemical diversity.

Ectomycorrhizal fungi establish mutually beneficial relationships with trees, trading nutrients for carbon. Suillus are ectomycorrhizal fungi that are critical to the health of boreal and temperate forest ecosystems. Comparative genomics has identified a high number of non-ribosomal peptide synthetase and terpene biosynthetic gene clusters (BGC) potentially involved in fungal competition and communication. However, the functionality of these BGCs is not known. This study employed co-culture techniques to activate BGC expression and then used metabolomics to investigate the diversity of metabolic products produced by three Suillus species (Suillus hirtellus EM16, Suillus decipiens EM49, and Suillus cothurnatus VC1858), core members of the pine microbiome. After 28 days of growth on solid media, liquid chromatography-tandem mass spectrometry identified a diverse range of extracellular metabolites (exometabolites) along the interaction zone between Suillus co-cultures. Prenol lipids were among the most abundant chemical classes. Out of the 62 unique terpene BGCs predicted by genome mining, 41 putative prenol lipids (includes 37 putative terpenes) were identified across the three Suillus species using metabolomics. Notably, some terpenes were significantly more abundant in co-culture conditions. For example, we identified a metabolite matching to isomers isopimaric acid, sandaracopimaric acid, and abietic acid, which can be found in pine resin and play important roles in host defense mechanisms and Suillus spore germination. This research highlights the importance of combining genomics and metabolomics to advance our understanding of the chemical diversity underpinning fungal signaling and communication.IMPORTANCEUsing a combination of genomics and metabolomics, this study's findings offer new insights into the chemical diversity of Suillus fungi, which serve a critical role in forest ecosystems.

A triple-crosslinking strategy for high-performance regenerated cellulose fibers derived from waste cotton textiles

Regenerated cellulose fibers has attracted increasing attention for high-grade textile raw materials and industrial textiles, but the low mechanical property caused by differences in regenerated raw materials and production levels limits its commercial application in the product diversity. Herein, we proposed a novel triple-crosslinking strategy by coupling with hydrogen bonds, chemical crosslinking, and internal mineralization from multiple pulsed vapor phase infiltration (MPI) to improve the mechanical performance of regenerated cellulose fibers. A binary solvent composed of ionic liquid (IL) and dimethyl sulfoxide (DMSO) is used to dissolve waste cotton textile and then wet spinning. Dual-crosslinking is firstly achieved by coupling glutaraldehyde (GA) and cellulose reaction. Subsequently, a metal oxide is intentionally infiltrated into inner cellulosic through MPI technology to form a third form of crosslinking, accompanied by the ultra-thin metal oxide nano-layer onto the surface of regenerated cellulose fibers. Results showed that the triple-crosslinking strategy has increased the tensile stress of the fiber by 43.57 % to 287.03 MPa. In all, triple-crosslinking strategy provides a theoretical basis and technical approach for the reinforcement of weak fibers in waste cotton recycling, which is expected to accelerate the development of the waste textile recycling industry and promote of the added-value of regenerated products.

Ethanol Extracts from Torreya grandis Seed Have Potential to Reduce Hyperuricemia in Mouse Models by Influencing Purine Metabolism.

The purpose of this study was to evaluate the efficacy of ethanol extracts from Torreya grandis seed (EST) as a functional food in hyperuricemia mice. We investigated EST by analyzing its chemical composition. Using a mouse model of hyperuricemia induced by potassium oxonate (PO), we evaluated the effects of EST on uric acid (UA) production, inflammation-related cytokines, and gut microbiota diversity. The primary constituents of EST consist of various flavonoids and phenolic compounds known for their antioxidant and anti-inflammatory properties in vitro. Notably, our findings demonstrate that EST significantly reduced UA levels in hyperuricemia mice by 71.9%, which is comparable to the effects observed with xanthine treatment. Moreover, EST exhibited an inhibitory effect on xanthine oxidase activity in mouse liver, with an IC50 value of 20.90 μg/mL (36%). EST also provided protective effects to the mouse kidneys by modulating oxidative stress and inflammation in damaged tissues, while also enhancing UA excretion. Finally, EST influenced the composition of the intestinal microbiota, increasing the relative abundance of beneficial bacteria such as Akkermansia muciniphila, Corynebacterium parvum, Enterorhabdus, Muribaculaceae, Marvinbryantia, and Blautia. In summary, our research unveils additional functions of Torreya grandis and offers new insights into the future of managing hyperuricemia.

First Language Lexical Attrition in a First Language Setting: A Multi-Measure Approach Testing Teachers of English

Research on first language (L1) attrition typically focuses on immigrant populations in their second language (L2) environment, yet we know comparably little about L1 attrition in the L1 setting. This study used two lexical tasks to test L1 attrition, a time-sensitive word decision task and a video retelling. Chinese teachers of English vs. Chinese teachers of other subjects (N = 25/group) were recruited at a secondary school in China. The aim was to provide an exploratory basis of the L2 influence on L1 lexical attrition in the L1 environment, both on the level of lexical comprehension and production. Mixed-effects models were used to analyse multiple measures including response accuracy and reaction times in comprehension, and lexical diversity, density, sophistication, and accuracy in production. The results showed Chinese teachers’ L1 lexical attrition in the form of longer response times to high-frequency Chinese words compared to non-English Chinese teachers, and the use of significantly fewer sophisticated words in their retellings. Also, teachers of English were faster and more accurate in decisions about Chinese borrowings from English, suggesting L2-driven influence on their mental lexicon. Considering participants’ background information, analyses showed that increased L2 exposure and frequency of use can predict L1 lexical attrition.

Insights into intraspecific diversity of central carbon metabolites in Saccharomyces cerevisiae during wine fermentation

Saccharomyces cerevisiae is a major actor in winemaking that converts sugars from the grape must into ethanol and CO2 with outstanding efficiency. Primary metabolites produced during fermentation have a great importance in wine. While ethanol content contributes to the overall profile, other metabolites like glycerol, succinate, acetate or lactate also have significant impacts, even when present in lower concentrations. S. cerevisiae is known for its great genetic diversity that is related to its natural or technological environment. However, the variation range of metabolic diversity which can be exploited to enhance wine quality depends on the pathway considered. Our experiment assessed the diversity of primary metabolites production in a set of 51 S. cerevisiae strains from various genetic backgrounds. Results pointed out great yield differences depending on the metabolite considered, with ethanol having the lowest variation. A negative correlation between ethanol and glycerol was observed, confirming glycerol synthesis as a suitable lever to reduce ethanol yield. Genetic groups were linked to specific yields, such as the wine group and high α-ketoglutarate and low acetate yields. This research highlights the potential of using natural yeast diversity in winemaking. It also provides a detailed data set on production of well known (ethanol, glycerol, acetate) or little-known (lactate) primary metabolites.

Designing a Contextualized Food-Based Strategy to Improve the Dietary Diversity of Children in Rural Farming Households in Central Uganda.

Food-based strategies have a high potential of improving the diet quality and reducing the prevalence of nutrient deficiencies in agriculture-dependent communities. Their design is however complex with trade-offs that are rarely systematically presented to allow replication and efficient contextualization. The systematic design of a food-based strategy to improve the dietary diversity of children in rural farming communities in Uganda. The intervention mapping protocol was used to provide a systematic approach to developing theory-based and evidence-based intervention methods and strategy. The priority behavioral and environmental determinants identified were related to food production, consumption, and efficacy while the personal determinants focused on knowledge, skills, self-efficacy, attitude, and outcome expectations. The aim of the resulting strategy was set to improve the availability, accessibility, and consumption of diverse foods, with a particular focus on production diversity, production practices, market access, and market diversity. Behaviour change methods were selected to enhance ability and self-efficacy, strategic goal setting, and provision of feedback. The strategy focused on household groups for learning, demonstration, practice, and social support. The validation showed that the determinants and actors incorporated in the strategy were important and relevant for improving the productivity, food availability, dietary diversity, livelihoods, and health of rural farming households and communities. Application of the protocol yielded a contextualized food-based strategy that can be adjusted for use in other smallholder contexts in developing countries by piloting implementation plans based on the strategy; reassessing the key determinants and implementing the revised strategy; or replicating the whole design process.

Production Choices and Food Security: A Review of Studies Based on a Micro-Diversity Perspective.

Given the 'subsistence' character of smallholder production, agricultural production diversification is often seen as an effective strategy for smallholders to improve their diets' diversity and nutritional status, yet the existing evidence remains inadequate. The study applies bibliometric data from the "Web of Science" database to synthesize 46 papers from developing countries to explore the relationship between production diversity, dietary diversity, and nutrition in smallholder households. The study identifies the most influential journals, authors, organizations, and countries and reveals research themes related to agricultural production and food security. This data analysis can help researchers target potential collaborators and access influential literature in agricultural production diversity and dietary diversity research. In addition, the results showed that agricultural production diversity potentially influences households' dietary diversity, with mixed results: Agricultural production diversification is the primary way to improve food and nutritional security among smallholder families with low socio-economic status, inaccessible transportation, and poverty; market access and trade have more potential to improve dietary diversity among smallholder households with well-developed markets and higher income levels; the significant measures of agricultural production diversity include Crop Counts, FGPD, SI, and SWDI; the significant measures of dietary diversity include HDDS and IDDS. This paper provides a roadmap for agricultural production and food security researchers by conducting a systematic review of the literature, summarizing some research methods and perspectives applicable to local socio-economic development.

Doping engineering in S–scheme composite for Regulating the selectivity of photocatalytic CO2 reduction

Regulating product selectivity in photocatalytic CO2 reduction to enhance the yield of valuable hydrocarbons remains a formidable challenge because of the diversity of reduction products and the competitive reduction of H2O. Herein, ultrathin Bi2O3/ Co–doped SrBi4Ti4O15 S–scheme photocatalysts (Co–BS) were synthesized using a hydrothermal method. The Bi2O3/Co–doped SrBi4Ti4O15 photocatalyst exhibited significantly higher selectivity for CH4 (62.3 μmolg−1) and CH3OH (54.1 μmolg−1) in CO2 reduction compared with pure SrBi4Ti4O15 (27.2 and 0.8 μmolg−1) and the Bi2O3/SrBi4Ti4O15 S–scheme without Co (30.2 and 0 μmolg−1). The experimental results demonstrated that the inclusion of Co into SrBi4Ti4O15 expanded the range of light absorption and generated an internal electric field between Co–doped SrBi4Ti4O15 and Bi2O3. Density functional theory calculations and other experimental findings confirmed the formation of a new doping energy level in the Bi2O3/SrBi4Ti4O15 S–scheme heterojunction after Co doping. The valence band electrons of Bi2O3/SrBi4Ti4O15 transitioned to the Co–doped level because of the interconversion between Co3+ and Co2+ under the action of the internal electric field. Furthermore, the corresponding characterizations revealed that the adsorption and electron transfer rates of the surface active sites were accelerated after Co doping, enhancing electron involvement in the photocatalytic reaction process.This study presented a metal–doped S–scheme heterojunction approach for CO2 reduction to produce high–value products, enhancing the conversion of solar energy into energy resources.

Deterring the Gray Market: Product Diversion Detection via Learning Disentangled Representations of Multivariate Time Series

A gray market emerges when some distributors divert products to unauthorized distributors/retailers to make sneaky profits from the manufacturers’ differential channel incentives, such as quantity discounts. Traditionally, manufacturers rely heavily on internal audits to periodically investigate the flows of products and funds so as to deter the gray market; however, this is too costly given the large number of distributors and their huge volumes of orders. Owing to the advances in data analytics techniques, the ordering quantities of a distributor over time, which form multivariate time series, can help reveal suspicious product diversion behaviors and narrow the audit scope drastically. To that end, in this paper, we build on the recent advancement of representation learning for time series and adopt a sequence autoencoder to automatically characterize the overall demand patterns. To cope with the underlying entangled factors and interfering information in the multivariate time series of ordering quantities, we develop a disentangled learning scheme to construct more effective sequence representations. An interdistributor correlation regularization is also proposed to ensure more reliable representations. Finally, given the highly scarce anomaly labels for the detection task, an unsupervised deep generative model based on the learned representations of the distributors is developed to estimate the densities of distributions, which enables the anomaly scores generated through end-to-end learning. Extensive experiments on a real-world distribution channel data set and a larger simulated data set empirically validate our model’s superior and robust performances compared with several state-of-the-art baselines. Additionally, our illustrative economic analysis demonstrates that the manufacturers can launch more targeted and cost-effective audits toward the suspected distributors recommended by our model so as to deter the gray market.

Three Decades of Groundwater Drought Research: Evolution and Trends

In most parts of the world, groundwater is the main source of their water supply, particularly during periods of drought when surface water is scarce. As a result, groundwater drought is among the most worrying problems of our time. In order to shed light on the diversity of scientific productions related to this theme, this analysis was conducted on 151 publications, 76 sources, and 469 authors using version 4.3.1 of Rstudio’s Bibliometrix tool. The clusters and keyword occurrence analysis reveals a research trend towards the use of advanced technologies and a more holistic approach that takes into account the complexity of hydrological systems. The use of drought indices to characterize and monitor groundwater drought, as well as satellite products and their assimilation into Land Surface Models are among the adopted solutions. This was endorsed through a summary of the five most cited publications in this field. The results also highlighted the performance of Chinese institutions in analyzing the various aspects related to this topic, as well as a lack of international collaboration between research structures. In conclusion, this study has enabled us to present the evolution and trends in scientific research and helped to specify the main emerging themes and future areas of research related to groundwater drought.
