How do thrombolites form? Multiphase construction of lacustrine microbialites, Purbeck Limestone Group, (Jurassic), Dorset, UK

This paper examines how non‐marine thrombolites are formed through a complex, multiphase process of microbial framework construction, erosion, cementation, recrystallization and episodes of internal sedimentation. Recognition of such phases of thrombolite construction provides a framework for the interpretation of the fluctuating environmental conditions leading to their formation. Microbialite frameworks are examined in detail from the Purbeck Limestone Group and their affinities and palaeo‐environmental significance assessed. Three types of thrombolite, one stromatolite and a leolite are described and interpreted. The thrombolite frameworks include: a peloidal mesoclotted type, a thrombolite constructed by the filamentous alga Cladophorites and a type with concentrically laminated micritic mesoclots. Physical and chemical erosion led to extensive early cavity formation within the frameworks. Early calcite rim cements with associated spherulites then developed over the microbial frameworks and these were reworked into cavities. Frameworks were also replaced by chalcedonic quartz and calcite spherulites. Internal sediments comprise peloids, intraclasts and brackish‐water molluscs and ostracods, together with their debris. The thrombolites grew in moderate‐energy to high‐energy shallow, lacustrine, microbial mounds whereas stromatolites occurred in deeper‐water settings. A brackish‐water, lacustrine setting is indicated by the preserved macro‐biota, microbes, absence of charophytes and syndepositional evaporites, and negative stable carbon and oxygen isotope ratios. Strontium isotopes suggest that the carbonate‐rich waters were fed from erosion of Mid–Lower Jurassic limestones on the western basin margin with possible mixing with waters from nearby uplifted Upper Jurassic limestones and with Late Jurassic seawater. The research indicates that non‐marine thrombolites have a complex, multiphase origin resulting in a diverse succession of textures and structures relating to microbially induced and influenced construction, dissolution, cementation, recrystallization and mineral replacement which have not been previously recorded and indicate the major differences between marine and non‐marine thrombolites.
Evaluation of Resistant Tea (Camellia sinensis L.) Clones Against Helopeltis bradyi

Helopeltis bradyi is a significant pest that causes yield losses and reduces the quality of tea plantations by piercing and sucking the sap of tea leaves. This pest can be appropriately controlled by using resistant clones. The PGL series (clones) owned by Pagilaran plantation has high yield and quality. However, information their resistance level against H. bradyi is limited. This research was conducted at Pagilaran tea plantation at an altitude of 990 masl. Six PGL clone series (PGL 4, PGL 6, PGL 9, PGL 10, PGL 11, and PGL 15) and control clones (TRI 2025 and Gambung 7) were used as plant materials. Their morphological and biochemical characteristics were determined to evaluate their resistance level against H. bradyi. The results revealed that the score symptoms (under 10%) of PGL 4, PGL 9, PGL 10, PGL 11, and PGL 15 clones were the lowest, so these clones were categorized to be highly resistant. In addition, the total phenol content and trichome density of PGL 4, PGL 10, and PGL 15 clones were the highest. Among them, the PGL 4 clone had the thickest epidermis. These characteristics likely contributed to the morphological and biochemical defence mechanisms of tea plants against H. bradyi.
Earth’s Albedo and Its Symmetry

The properties of Earth's albedo and its symmetries are analyzed using twenty years of space‐based Energy Balanced And Filled product of Clouds and the Earth's Radiant Energy System measurements. Despite surface asymmetries, top of the atmosphere temporally & hemispherically averaged reflected solar irradiance R appears symmetric over Northern/Southern hemispheres. This is confirmed with the use of surrogate time‐series, which provides margins of 0.1±0.28Wm−2 for possible hemispheric differences supported by Clouds and Earth's Radiant System data. R time‐series are further analyzed by decomposition into a seasonal (yearly and half yearly) cycle and residuals. Variability in the reflected solar irradiance is almost entirely (99%) due to the seasonal variations, mostly due to seasonal variations in insolation. The residuals of hemispherically averaged R are not only small, but also indistinguishable from noise, and thus not correlated across hemispheres. This makes yearly and sub‐yearly timescales unlikely as the basis for a symmetry‐establishing mechanism. The residuals however contain a global trend that is large, as compared to expected albedo feedbacks. It is also hemispherically symmetric, and thus indicates the possibility of a symmetry enforcing mechanism at longer timescales. To pinpoint precisely which parts of the Earth system establish the hemispheric symmetry, we create an energetically consistent cloud‐albedo field from the data. We show that the surface albedo asymmetry is compensated by asymmetries between clouds over extra‐tropical oceans, with southern hemispheric storm‐tracks being 11% cloudier than their northern hemisphere counterparts. This again indicates that, assuming the albedo symmetry is not a result of chance, its mechanism likely operates on large temporal and spatial scales.
Remotely sensed applications in monitoring the spatio-temporal dynamics of pools and flows along non-perennial rivers: a review

ABSTRACT Non-perennial rivers (NPRs) account for more than 50% of the world’s river network and their occurrence is expanding. Some rivers that were previously classified as perennial have evolved to be NPRs in response to climate change and socio-economic uses. There is inadequate understanding of the spatio-temporal dynamics of flows and pools along these rivers due to lack of data, as a priority of river monitoring has been placed on perennial rivers. The current understanding and methods used for monitoring NPRs are mostly derived from perennial rivers perspective. This review paper examines challenges for collecting data on these hydrological attributes of NPRs using current methods. Furthermore, this paper provides an overview of the potential and limitations of using remote sensing data for monitoring NPRs. Remote sensing data are successfully used for monitoring wetlands and lakes, but little is known about their capabilities for monitoring pools along NPRs. Remote sensing has also been successfully used to estimate discharge of large perennial rivers; however, this has not been fully explored for NPRs. Remote sensing has the potential to extract more hydrological information that currently cannot be extracted using conventional in-situ measurement methods. With advancements, remote sensing technology could become useful for managing NPRs.
Multi-Trait Selection Indices for Identifying New Cassava Varieties Adapted to the Caribbean Region of Colombia

In Colombia, the highest cassava production comes from the semi-arid region of the Atlantic Coast with relatively low yield for fresh consumption (≤11 t/ha). Development of improved varieties is based on a plant ideotype which integrates a group of desirable traits independently measured in the field. However, selecting high performance genotypes for several traits simultaneously is a complex process. Sixteen genotypes were evaluated under four environmental conditions (localities) of the Colombian Caribbean region (Cereté, Carmen de Bolivar, Agustín Codazzi, and Sevilla), and two production cycles (2016/2017–2017/2018) in order to assess phenotypic expression of selected traits, their stability, and utility in genotype selection. Selection of promising genotypes should consider both their superiority and stability. Genotypes SM3106-14, GM1692-56, CM9456-12, and GM214-62 were selected based on their agronomic performance. In addition, frequency analysis of sensorial data showed that genotypes CM9456-12, SM1127-8, SM3553-27, and SM3562-32 were preferred by panelists who assessed, color, flavor, texture, and root shape. Determination of superiority through across-environments, multi-trait selection index allows identifying genotypes with superior performance. However, selection was improved when local multi-trait selection indices were included—phenotypic stability determination (through Lin and Binns index and AMMI model) supported an adequate selection of superior and stable cassava genotypes. The inclusion of palatability response and quality features determination in cassava genotypes can be recommended to identify genotypes with higher adoption rates by farmers and consumers.
Trade-Policy Dynamics: Evidence from 60 Years of U.S.-China Trade

This paper studies the growth of Chinese imports into the United States from autarky during 1950–1970 to about 15 percent of overall imports in 2008, taking advantage of the rich heterogeneity in trade policy and trade growth across products during this period. Central to the analysis is an accounting for the dynamics of trade, trade policy, and trade-policy expectations. The analysis isolates the lagged effects of past reforms and the current effects of uncertainty about future reforms. It builds a multi-industry, heterogeneous-firm model with a dynamic export participation decision to estimate a path of trade-policy expectations. The findings show that being granted Normal Trade Relations (NTR) status in 1980 was largely a surprise and that, in the early stages, this reform had a high probability of being reversed. The likelihood of reversal dropped considerably during the mid-1980s, and, despite China’s accession to the World Trade Organization (WTO) in 2001, changed little throughout the late 1990s and early 2000s. Thus, although uncertainty depressed trade substantially following the 1980 liberalization, much of the trade growth that followed China’s WTO accession was a delayed response to previous reforms rather than a response to declining uncertainty.
Does Neighborhood Status Affect Access to a Healthy Built Environment?

Background: When looking to better understand the links between income and health, urban settings add an additional dimension of structural inequity. Without proactive urban planning, some neighborhoods are deprived of essential services, while other neighborhoods enjoy easier access to services and providers. The case of Indore, India was used to explore differentials in available services, infrastructure, and access to goods and services relating to non-communicable disease risk when the data was disaggregated by neighborhood type (slum vs non-slum). Methods: The environmental data for this paper came from a city-wide multi-level survey conducted in 2018, which included a neighborhood environmental assessment tool adapted from pre-validated questionnaires. Wards were randomly selected using a probability proportional to size (PPS) method after stratification by presence of slums. Within each ward, three colonies were then selected by PPS. The environmental data were collected from the same 30 wards and 93% (84/90) of the same colonies as the individual data. Results: The analysis highlighted some expected inequalities by neighborhood status, such as neighborhoods with no parks (62% slum vs 31% in non-slum). In neighborhoods where parks were present, there appeared to be issues with safety within the parks. Regarding walkability, slum neighborhoods generally had a higher prevalence of broken glass, liquor bottles, and stray dogs on footpaths. Non-slum neighborhoods had, on average, more vegetable stores, while slum neighborhoods had more snack and tobacco stores. The ratio of pro-tobacco versus anti-tobacco ads was twice as bad in slums than in non-slums. Conclusion: Better understanding of the access and availability of green spaces, transportation, and food markets between neighborhoods will help local officials, developers, and citizens as they formulate more equitable ways to distribute resources to build healthier environments for all citizens.

Multimarket Contact, Income Diversification and Bank Performance

Abstract Faced with intense competition, banks may find geographic and income diversification strategies indispensable to remain competitive. Surprisingly, the literature has only discussed the two strategies separately, and there appears little effort in considering both strategies simultaneously, at least in the investigation of their intertwined impact on bank performance. We adopt System Generalized Method of Moments for a panel dataset covering commercial banks in Vietnam to investigate the impact of these diversification strategies on bank performance. The research findings suggest that multimarket contact has a positive impact on performance, supporting the mutual forbearance hypothesis. Income diversification is also positively related to bank profitability. Importantly, our results show that the interaction between multimarket contact and income diversification has a negative effect on bank profitability. This evidence implies that facing with multimarket contacts, a bank with diversified businesses is more likely to choose to compete, thus raising the competition and lowering its profitability.
The Functions and Features of ELT Textbooks and Textbook Analysis: A Concise Review

Decades of research have established that most English Language Teaching (ELT) contexts rely on textbooks and corresponding materials to drive the education process. Textbook analysis as a vital quality control check of these products has also become a popular trend in applied linguistics and second language (L2) research. In the main, ELT textbooks have been conceptualized in past literature as supporting target language proficiency attainment while also giving the teacher everything required to conduct a lesson. Textbook analysis has subsequently checked products’ utility and quality in relation to such proficiency development. Over time, the scope of textbook analyses has expanded to include issues such as cultural representations in these products to address how the products help students become better at English in a multicultural and globalized world. While teachers and researchers can reference numerous well-known books on these phenomena, a concise summary of how textbooks function within ELT contexts and the defining features of textbook analysis research appears to be lacking. This brief report meets this need and is useful to stakeholders in the ELT community, such as teachers and program managers, who might not have the time nor the resources to consult such extensive sources of information.
Magnitude and mechanisms of nitrogen‐mediated responses of tree biomass production to elevated CO2: A global synthesis

Elevated atmospheric CO2 concentration (eCO2) typically stimulates tree growth, which is mediated by nitrogen (N) availability; but how N regulates tree biomass responses to eCO2 remains uncertain, which limits our prediction of forest carbon (C) cycling under future global change scenarios. A meta‐analysis of a global dataset including 3,399 observations from 283 papers published from 1980s to February 2021 was conducted with the aim of elucidating N‐mediated responses of tree biomass production to eCO2 and the underlying mechanisms. We found that eCO2 stimulated tree biomass production (+32.0%), while it induced accumulation of non‐structural carbohydrates in leaves rather than in woods and roots, suggesting that the production may be C‐limited but depend on the sink strength of organs. Biomass responses to eCO2 of N‐fertilized trees (+39.6%) were 68.4% greater than those of non‐fertilized trees (+23.5%), confirming that tree growth is also N‐limited. Such N limitation was alleviated by the eCO2‐induced increases in N uptake and N‐use efficiency (NUE), with the former being more important. Increases in tree N pool arose from the enhanced production of fine roots with a lower specific root length, whereas increases in NUE resulted from the flexibility in tissue C:N ratios instead of N resorption efficiency. The positive responses of tree biomass production to eCO2 were greater for ectomycorrhizal trees and conifers than for arbuscular mycorrhizal trees and angiosperms, respectively. Synthesis. Our findings suggest that eCO2 stimulates tree biomass production by increasing C availability, and alleviating N limitation in a feedback way via enhancing N uptake and NUE, and they improve our mechanistic understanding of responses of forest productivity and C sequestration to eCO2 under global change.
Impact of Mixing on the Structural Diversity of Serbian Spruce and Macedonian Pine Endemic to Relict Forest Communities in the Balkan Peninsula

The aim of this paper is to analyze the effect of different degrees of mixing on the diversity structure in stands left to spontaneous development. The research included two communities of species endemic to the Balkan Peninsula—the Serbian spruce (Picea omorika Pančić Purk.) and the Macedonian pine (Pinus peuce Griseb). Data from eight sample plots were used in the research. The changes in diameter and height structure, spatial arrangement of trees, and diameter differentiation were analyzed. The analyzed parameters of structural diversity show relatively low to moderate values. Results showed an increase in mixing was reflected in the width and shape of distributions. A spatial analysis of stands with a higher degree of mixing showed a tendency towards a random to regular distribution of individuals, in contrast to stands with a lower degree of mixing which showed a tendency towards a clump distribution. The pronounced species’ dimensional and spatial diversity confirms their importance to the condition of modern forest management. Significant differences in the change of structure are shown by stands with a share of admixed species of above 20% by volume. The obtained results refer to stands left to spontaneous development, suggesting than an active research and management approach must be assumed to realize the goal of protecting rare forest ecosystems.
Neither historical climate nor contemporary range fully explain the extant patterns of molecular diversity in marine species

Intraspecific diversity is a significant component of adaptive potential, and thus, it is important to identify the evolutionary processes that have and will continue to shape the molecular diversity of natural populations. This study aims to untangle the possible drivers of intraspecific molecular diversity by testing whether patterns of historical climatic stability or contemporary range position correlate with molecular diversity.
Literature Review: The Effectiveness of Giving Ginger (Zingiber Officinale Roscoe) to Pregnant Women Nausea Vomiting 1st Trimester Pregnancy

Nausea and vomiting often occur when you wake up in the morning, which is also called morning sickness. Nausea and vomiting that occur in the first trimester of pregnancy are caused by increased levels of the hormone Estrogen and Human Chorionic Gonadotropine (HCG) in serum from the placenta and can cause a decrease in appetite so that there is a change in electrolyte balance with potassium, calcium and sodium which causes changes in body metabolism. Nausea and vomiting during pregnancy affects about 80-90% of pregnant women. Ginger (Zingiber officinale Roscoe) is the most widely used herbal therapy in the management of nausea and vomiting. The purpose of this study was to determine how effectiveness ginger was in reducing the frequency of nuesea and vomiting in pregnant women in the 1st trimester.This study uses a literature study method obtained through electronic media with keywords. There were 8 selected articles, consisting of 5 international and 3 national articles. This article provides information about the effectiveness of giving ginger to reduce the frequency of nausea and vomiting in pregnant women in the 1st trimester. The conclusions obtained from the analysis are that ginger can reduce nausea and vomiting in pregnant women in the 1st trimester.
Characterization and Technological Potential of Underutilized Ancestral Andean Crop Flours from Ecuador

Ancestral Andean crop flours (ACF) from Ecuador such as camote (Ipomea Batatas), oca (Oxalis tuberosa), achira (Canna indica), mashua (Tropaeolum tuberosum), white arracacha (Arracacia xanthorrhiza), taro (Colocasia esculenta) and tarwi (Lupinus mutabilis sweet) were characterized in terms of physico-chemical and techno-functional properties in order to identify their potential as new alternative ingredients in food products. Flour from camote, oca, achira and arracacha showed a low protein content (<5%), mashua and taro had ~9% and tarwi flour registered higher values than 52%. Carbohydrate content ranged from 56–77%, with the exception of tarwi, just reaching 6.9%. Starch content was relatively low in ACF but in taro and tarwi, starch practically constituted almost all the carbohydrates. The highest amylose content in starch, in decreasing order, was found in mashua, oca, tarwi and achira flours, the rest being ≤15%. Fiber content exceeded 10% in most crops, except for oca flour with 5.33%. Fat content was generally lower than 1%, except in tarwi with ~17%. All flours showed a gel-like behavior G′ > G″, this being very similar in camote, achira and tarwi flours. The exception was taro with G′ < G″. Mashua flour registered the highest value for phenol content (60.8 µg gallic acid equivalents/g of sample); the content of phenols was not exclusively responsible for the antioxidant activity, since flours with the highest activity were arracacha and tarwi, which presented the lowest phenol content among all flours. Principal component analyses (PCA) showed a high correlation between moisture, fiber, solubility and water absorption capacity, with viscoelastic behavior and total phenolic content; while starch content was correlated with melting temperature, poorly and inversely related to protein and fat. For PC1, achira, camote and taro flours were very similar, and different from oca and mashua flours. Tarwi showed its own characteristics according to PC1 and 2. Because of their properties, Andean crop flours could have a great potential for use in food technology.
Warm Acclimation Increases Mitochondrial Efficiency in Fish: A Compensatory Mechanism to Reduce the Demand for Oxygen

In ectotherms, it is well described that thermal acclimation induces compensatory adjustments maintaining mitochondrial functions across large shifts in temperature. However, until now, studies mostly focused on fluxes of oxygen without knowing whether mitochondrial efficiency to produce ATP (ATP/O ratio) is also dependent on temperature acclimation. We thus measured thermal reaction norms of oxidative phosphorylation activity and efficiency in isolated mitochondria from skeletal muscle of sea bass (Dicentrarchus labrax) juveniles acclimated at optimal (22°C), low (18°C), and high (26°C) temperatures. The mitochondrial fluxes (oxygen consumption and ATP synthesis) increased with increasing assay temperatures and were on the whole higher in fishes acclimated at 18°C than in the other two groups. However, these mitochondrial rates were not significantly different between experimental groups when they were compared at the acclimation temperature. In contrast, we show that acclimation to high, and not low, temperature improved mitochondrial efficiency (on average >15%). This higher efficiency in high-temperature-acclimated fishes is also apparent when compared at respective acclimation temperatures. This mitochondrial phenotype would favor an economical management of oxygen in response to harsh energetic constraints associated with warming water.
