Assessing Molecular Localization of Symbiont Microalgae in Coral Branches Through Mass Spectrometry Imaging.

Reef-building corals are a fundamental pillar of coral reef ecosystems in tropical and subtropical shallow environments. Corals harbor symbiotic dinoflagellates belonging to the family Symbiodiniaceae, commonly known as zooxanthellae. Extensive research has been conducted on this symbiotic relationship, yet the fundamental information about the distribution and localization of Symbiodiniaceae cells in corals is still limited. This information is crucial to understanding the mechanism underlying the metabolite exchange between corals and their algal symbionts, as well as the metabolic flow within holobionts. To examine the distribution of Symbiodiniaceae cells within corals, in this study, we used fluorescence imaging and matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MS-Imaging) on branches of the Acropora tenuis coral. We successfully prepared frozen sections of the coral for molecular imaging without fixing or decalcifying the coral branches. By combining the results of MS-Imaging with that of the fluorescence imaging, we determined that the algal Symbiodiniaceae symbionts were not only localized in the tentacle and surface region of the coral branches but also inhabited the in inner parts. Therefore, the molecular imaging technique used in this study could be valuable to further investigate the molecular dynamics between corals and their symbionts.

Envisioning sustainability through (un)shared professional visions of the “visual” materials of a design situation: a CCO approach

PurposeCommunicating a clear, precise, interpretable and unambiguous visual message usually relies on a cross-disciplinary team of professionals. Their complementary visions can uncover which information matter and how it could be visually displayed to inform, sensitize and encourage people to act toward sustainability. While design studies generally claim that this team has to come to a shared vision, the authors question this assumption, which seems to contradict the benefits of cross-disciplinarity. The purpose of this study is to reveal how simple visual representations displayed in a PowerPoint actively participate in the expression of various and sometimes divergent visions. Recognizing the agency of visuals also leads this study to propose the notion of (un)shared professional vision, which shows that the richness of visual representations can only reveal itself through the capacity of professional visions to maintain their differences while confronting each other.Design/methodology/approachOver a 20-month ethnography, this study documented its own cross-disciplinary reflective design process, which aimed to design collectively an experimental environmental label, focusing on interactions occurring between professionals and visuals displayed on five key PowerPoint slides.FindingsThis study first demonstrates how, in practice, a cross-disciplinary reflective design conversation with visuals concretely unfolds through boundary-objects. This study shows how these visuals manage to ex-press themselves through the multiple visions represented in the discussions, revealing their complexity. Second, this study introduces the notion of (un)shared professional vision which underlines that unsharing a vision nurtures the team’s collective capacity to express the complexity of a design situation, while sharing a vision is also necessary to confront these respective expressions to allow the professional uncovering of what should be visually communicated.Originality/valueThe Communication as Constitutive of Organization lens the authors chose to understand the reflective design conversation illustrates that, even though each collaborator’s vision was “(un)shared,” their many voices expand the understanding of the situation and lead them to develop an unexpected and creative environmental information ecosystem that can positively transform society through visuals.

Nitrogen loading resulting from major floods and sediment resuspension to a large coastal embayment

Major floods pose a severe threat to coastal receiving environments, negatively impacting environmental health and ecosystem services through direct smothering with sediment and nutrient loading. This study examined the short and long-term impacts of the February 2022 major flood event on mud extent and sediment nitrogen flux in Moreton Bay (the Bay), a large, sub-tropical embayment in Southeast Queensland, Australia. Short-term impacts were assessed three days after the flood peak by sampling surface water at 47 sites in the direction of the predominant circulation pattern. Longer-term impacts were assessed by undertaking an intensive sediment survey of 223 sites and a nutrient flux experiment using sediment core incubations to simulate calm and resuspension conditions for the four key sediment classes. Short-term impacts revealed elevated turbidity levels extended across the Bay but were highest at the Brisbane River mouth, ammonium concentrations varied inversely with surface turbidity, whereas nitrate concentrates closely tracked surface turbidity. The sediment survey confirmed fine sediment deposition across 98 % of the Bay. Porewater within the upper 10 cm contained a standing pool of 280 t of ammonium, with concentrations more than three orders of magnitude higher than overlying surface waters. The nutrient flux experiment revealed an order of magnitude higher sediment ammonium flux rate in the sandy mud sediment class compared to the other sediment classes; and for simulated resuspension conditions compared to calm conditions for sand, muddy sand, and mud sediment classes. Scaling across the whole Bay, we estimated a mean annual sediment flux of 17,700 t/year ammonium, with a range of 13,500 to 21,900 t/year. Delivery of fine sediments by major floods over the last 50 years now impact >98 % of the benthic zone and provide a major loading pathway of available nitrogen to surface waters of Moreton Bay; representing a significant threat to ecosystem health.

Assessing the Connectivity of Urban Green Spaces for Enhanced Environmental Justice and Ecosystem Service Flow: A Study of Tehran Using Graph Theory and Least-Cost Analysis

This research aims to analyze the relationship between environmental justice and urban green space connectivity in Tehran, Iran. The evaluation of green space connectivity in this study is conducted through two distinct cost layers: one aimed at enhancing existing connections and another focused on establishing new green spaces. Key factors influencing connectivity, extracted from the relevant literature, were identified to facilitate this analysis. Employing graph theory and least-cost analysis, the results determined critical resistance factors, current connectivity and cost status, the varying degrees to which different districts benefit from green space ecosystem services, and the most effective routes for establishing green corridors. Research findings highlight significant disparities in access to these services, particularly in the underserved central districts of Tehran. Moreover, spatial analysis reveals a higher potential for enhancing east–west ecosystem service corridors due to the higher density of green hubs and lower costs in this orientation, while north–south connectivity faces more challenges. By exploring land use/land cover, and physical and socio-economic factors affecting urban green space connectivity, this study provides urban and environmental planners with a novel methodology and comprehensive insights for effective decision making, resource allocation, and land use planning.

Identification of environmental Actinobacteria in buildings by means of chemotaxonomy, 16S rRNA sequencing, and MALDI-TOF MS.

The manuscript addresses the challenges in identifying environmental bacteria using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) Biotyper-based protein profiling. The matter of the studies-actinobacterial strains-has been isolated mostly from building materials that originated from a confirmed moisture-damaged situation. Polyphasic taxonomy, 16S RNA gene sequencing, and MALDI-TOF mass spectrometry were applied for identification purposes. In this experimental paper, a few important facts are highlighted. First, Actinobacteria are abundant in the natural as well as built environment, and their identification on the species and genus levels is difficult and time-consuming. Second, MALDI-TOF MS is an effective tool for identifying bacterial environmental strains, and in parallel, continuous enrichment of the proteomics mass spectral databases is necessary for proper identification. Third, the chemical approach aids in the taxonomical inquiry of Actinobacteria environmental strains.

INDIAN CRAFTS AND SUSTAINABLE NATURAL DYES

Indian crafts reflect the most commonly from different parts of the country practice several art forms and crafts, and their identities are associated with where they carry a significant part of their culture and tradition. Most of these art forms are practised for ages and passed from generation to generation. Most of these are folk and traditional, and regional art forms have local religious themes, community values, cultural practices, and various traditional beliefs. Our country has several distinct folk and traditional arts in different regions of India. Among these most popular are Madhubani from the Mithila region of Bihar, Kalamkari Paintings, Kondapalli Toys, Etikoppaka Toys, Nirmal Toys from Andhra Pradeshand Telangana. Colours carry an important cultural significance in India. Here the researcher wants to focus mainly on the natural dyes used for these art forms, the influence of cultural diversity, and sustainability factors. Natural colors are extracted from plants and other natural sources for most of these art forms. Some of these started adopting artificial synthetic colour practices due to various reasons. Since the dawn of civilization, colour has influenced the human psyche from ancient times and played a significant role in the formation of different cultures of human beings worldwide. With the increasing demand in recent times for the use of natural and sustainable colours many industries started looking for natural bio-resource colours without any harmful effects on the environment and aquatic ecosystem. Current studies also spotlight a historical overview of natural colourants.

Evaluation of Multi-Source Precipitation Products in the Hinterland of the Tibetan Plateau

High-resolution precipitation products have been crucial for hydrology, meteorology, and environmental ecosystems over the Tibetan Plateau (TP). However, these products are usually subject to systematic errors, which may vary with time and topographic conditions. The study evaluated the suitability of four satellite-derived products (GPM IMERG, GSMaP, CMORPH, and PERSIANN-CDR) and four fusion precipitation products (ERA5-Land, CHIRPS, CMFD, and TPHiPr) by comparing with 22 rain gauges at a daily scale from 1 January 2014 to 31 December 2018 over the hinterland of the TP. The main findings are as follows: (1) TPHiPr and CMFD are better than the satellite-derived products, while the performance of CHIRPS is worse; (2) among the satellite-derived products, the quality of GPM IMERG is the highest on different time scales, and PERSIANN-CDR is better in the months of June to October, while GSMaP and CMORPH have poor performance; (3) the eight precipitation products have weaker detection capability for heavy precipitation events, and the quality of each product decreases with the increase in the precipitation threshold, while the rate of descent of fusion precipitation products is slower than that of satellite-derived products. This study demonstrates the performance of eight precipitation products over the hinterland of the TP, which is expected to provide valuable information for hydrometeorology applications.

The effects of gender political inclusion and democracy on environmental performance: Evidence from the method of moments by quantile regression

AbstractMotivated by the difficulty of ensuring gender equality and the chaotic state of democracy, we analyze the effects of gender political inclusion and democracy on environmental policy performance. The study uses a panel of 45 African countries over the period 2012–2018 and employs the method of moments by quantile regression. The results show that gender political inclusion and democracy positively affect environmental performance in all quantiles. These positive effects tend to be stronger at higher quantiles. The magnitude is larger for gender political inclusion. When performance is decomposed into the sub‐indices of environmental health and ecosystem vitality, positive effects of gender political inclusion and democracy are observed in all quantiles. The effects are larger for the gender dimension than for the democracy dimension, regardless of the sub‐index used.Related ArticlesBingham, Natasha. 2016. “Fighting for Our Cause: The Impact of Women's NGOs on Gender Policy Adoption in Four Former Soviet Republics.” Politics & Policy 44(2): 294–318. https://doi.org/10.1111/polp.12155.Hankivsky, Olena. 2013. “Gender Mainstreaming: A Five‐Country Examination.” Politics & Policy 41(5): 629–55. https://doi.org/10.1111/polp.12037.Nchofoung, Tii, Simplice Asongu, Vanessa Tchamyou, and Ofeh Edoh. 2022. “Gender, Political Inclusion, and Democracy in Africa: Some Empirical Evidence.” Politics & Policy 51(1): 137–155. https://doi.org/10.1111/polp.12505.

Strengthening the Quest for Sustainable Development Through Persuasive Climate Argumentation

This study explored the nexus between framing, persuasion and the quest for sustainable development in a competitive policy debate setting using content analysis approach. Evidence from the analysis reveals several insights about the underlying mechanism that governs persuasive climate argumentation which shapes sustainable development trajectory. First, the study showed that arguers construct arguments that appeals to logos as a major persuasion strategy. Second, it demonstrated how persuasion strategy entrench a culture of persuasion in climate debates. Third, it found a discordant relationship between fallacies and persuasion strategy in climate argumentation, which jeopardises arguments' persuasive power. Finally, the study evaluated how tensions in the mainstream socio-economic and environmental ecosystem creeps into climate arguments and limit persuasive power of climate arguments. These are regarded as reflective pattern of climate argumentation that are capable of stimulating behavioural change and communication strategies for sustainable development.

Persistent organic pollutants in the olive ridley turtle (Lepidochelys olivacea) during the nesting stage in the "La Escobilla" Sanctuary, Oaxaca, Mexico.

Persistent organic pollutants (POPs) are chemical substances widely distributed in the environment by the runoff from anthropic activities and can be distributed and bioaccumulated or biomagnified in the environment, affecting the health of organisms. The sea turtle, Lepidochelys olivacea, is a long-lived organism, with migratory habits and feeding behaviors that allow exposure to various pollutants. This work aimed to determine long-term exposure to POPs in adult olive ridley turtles (L. olivacea), sampled during the nesting season, in "La Escobilla" Sanctuary. Blood samples were collected and processed to obtain plasma. The quantification of POPs in blood was carried out with an extraction technique with a focused ultrasound probe. Twenty-seven POP analytes were determined. The concentrations of hexachlorocyclohexane, endosulfan isomers, dichlorodiphenyltrichloroethane, total polychlorinated biphenyls, and the total sum of POPs found in plasma are higher than those reported in other studies, which reported effects such as hematological and biochemical changes in blood, changes in immune system cells and enzymatic activity related to oxidative stress. These results are important to demonstrate the chronic exposure to POPs in olive ridley turtles in marine ecosystems and to highlight the importance of assessing the associated health risks, considering that these contaminants could be transferred to the offspring and affect future generations of this reptile. It is important to carry out studies that develop conservation strategies for the olive ridley turtle. Also, it is necessary to control the emissions of pollutants into the atmosphere, as well as reduce urban, agricultural, and industrial waste in the environment and marine ecosystems.

Assessment of Liver Toxicity in Wistar Rats after Chronic Exposure to Phosphate-Processing Wastewaters from Gafsa-Metlaoui Laundry in Tunisia

In the mining basin of the Gafsa region in southwestern Tunisia, environmental exposure to randomly discharged phosphate-processing wastewaters (PPWW) presents a serious threat to health and the surrounding ecosystems. Thus, the contaminated areas are in continuous deterioration over time. There is a paucity of information on the deleterious effects of this kind of effluent. In the current work, the PPWW characterization showed the presence of high contents of Pb (0.90 ± 0.02 mg/L), Cd (0.35 ± 0.27 mg/L), Cr (0.43 ± 0.1 mg/L) and Fe (215.1 ± 2.41 mg/L), exceeding the permissible limits. To assess the chronic toxicity of the effluent in mammalians, two doses of PPWW (50% and 100%) were administered by gavage to Wistar rats for 28 consecutive days. The results revealed that the two PPWW concentrations significantly increased the plasma biochemical markers (bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH)), compared to untreated animals. Moreover, PPWW treatment severely altered the lipid profile by increasing the contents of triglycerides, total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-cholesterol) by 143%, 114%, and 91%, respectively, and significantly reduced the high-density lipoprotein cholesterol (HDL-cholesterol) level by 46%, compared to the control animals. In addition to the significant decrease in activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) in the liver of intoxicated rats, the malondialdehyde (MDA) level was remarkably altered. All of these were associated with deep histopathological damages, materialized by dilatation of sinusoids, congestion of the centrilobular vein, and inflammatory cell infiltration. These disturbances were accompanied by metal detection in the liver and blood. Additionally, DNA fragmentation detected in hepatic tissues highlighted the genotoxic effects of PPWW. All of the aforementioned effects occurred in a PPWW dose-dependent manner. These findings evidenced, for the first time, the in vivo-deleterious impacts of this type of effluent on mammalians inhabiting the mining basin area and therefore showed the real threats to which humans, as consumers, could be exposed. Accordingly, there is a dire need to pay special attention to PPWW before being discharged into environmental ecosystems without any prior treatments.

The highest percentage of AMF infection was at the root of Sengon stands at 69% from the ex-sand mining area.

Rebooting Tourism in Vietnam: The Ho Tram Strip

Abstract: Over many years, the Government of Vietnam made various statements on the importance of sustainability and tourism sector growth. Corporate tourism developers quickly followed suit with similar rhetoric, as did some sociological scholarship—at times promoting tourism uncritically and sometimes critiquing it unapologetically. This article is based on ethnographic observations of casino tourism development along the Hồ Tràm strip on the South-eastern Vietnamese coastline, both before and during COVID-19, as well as close commentary monitoring government statements, corporate press, and promotional sociological studies within tourism management. The article addresses target markets for casino tourism, planning, infrastructure, issues for workers in associated sectors, and environmental ecosystems with longer, toxic histories. What 'sustainability' means after COVID-19 might be questioned in the 'rebooting' of the tourism economy.

Visual detection of microplastics using Raman spectroscopic imaging.

As a new type of pollutant in the marine environment and terrestrial ecosystems, microplastics have attracted widespread attention. Assessing the ecological risk of microplastics relies on accurately detecting small-sized particles in the environment. Microplastics exhibit unique "fingerprint" characteristics in Raman spectroscopy, making them suitable for rapid identification. In this study, we achieved visualization of microplastics through pseudo-color images generated by Raman spectroscopy imaging. Pseudo-color imaging maps were generated by selecting characteristic peaks and the classical least-squares fitting method was used to visually represent the distribution of different microplastics. The study explored the potential of Raman spectroscopy and its mapping mode in distinguishing various types of mixed microplastics and demonstrated that this approach can identify microplastics in complex environmental samples. Specifically, a cloud-point extraction followed by membrane filtration method was successfully applied to identifying mixed-component microplastics. In summary, the category, quantity, location, and differentiation of microplastics can be accurately analyzed by Raman spectroscopy, which provides a basis for assessing their ecological risk.
