115 years of sediment deposition in a reservoir in Central Europe: Effects of the industrial history and environmental protection on heavy metals and microplastic

AbstractHumans have considerably influenced accumulation rates and sediment composition in lake deposits. Due to near‐continuous accumulation, lakes and reservoirs are an excellent archive of these anthropogenic influences. The Urft Reservoir in the Eifel Mountains, western Germany, provides a unique record of the human influence on the landscape for the past 115 years. In 2020 and 2021, 24 cores and 23 surface samples were obtained from the bottom of the, by that time drained, reservoir. Grain size, heavy metals, weathering signatures and microplastic were analysed. For the chronology, caesium‐137 and microplastic were used. Using the first occurrence of microplastic as well as different plastic types for dating was not successful. However, a distinct layer with a high number of microplastic particles could be traced back to a fire in 1991 and was used as an additional stratigraphic marker in the age‐depth model. A period of relatively high accumulation rates in the reservoir occurred in the mid‐1950s and was related to enhanced construction works in the local valleys. Analysis of heavy metal content in the reservoir sediments shows a strong connection to historical changes in ore industry in the valley of the Urft. Stricter environmental protection laws and the decline of the metal processing industry resulted in a reduced input of lead, copper and zinc in the reservoir until the mid‐1980s. Since then, heavy metal content has remained relatively constant. A major flooding event in July 2021 did not lead to the remobilisation of older contaminated deposits as indicated by low heavy metal content in flood deposits. Accordingly, also the microplastic content is not increasing following the extreme event. Due to the degree of weathering of the flood deposits, it is argued that mainly hillslope material was transported into the Urft and subsequently into the Urft Reservoir during this event.

The link between human population dynamics and energy consumption during the Anthropocene

Our present world is the consequence of the size of the human population and its domination of the biosphere through the combustion of fossil fuels. Since ~1950, there has been a sudden increase in the rate of human global energy consumption, economic productivity, and population growth. This abrupt departure of the system dynamics has been defined as the “Great Acceleration.” The accelerated population and economic expansion during the past 70 years would have been impossible without using fossil fuels. However, no studies have made an explicit connection between human population dynamics on a global scale and historical changes in energy consumption growth rates, economic growth, and the energy return on investment of fossil fuels (EROI). In this study, I apply a simple population dynamic model of cooperation/competition to decipher the effects of changes in these factors on the dynamics of the human population during the period (1800–2020).

Capturing woody aboveground biomass historical change and potential under climate change using Landsat time-series for afforestation in dryland of China

Capturing long-term dynamics and the potential under climate change of woody aboveground biomass (AGB) is imperative for calculating and raising carbon sequestration of afforestation in dryland. It is always been a great challenge to accurately capture AGB dynamics of sparse woody vegetation mixed with grassland using only Landsat time-series, resulting in changing trajectory of woody AGB estimates cannot accurately reflect woody vegetation growth regularity in dryland. In this study, surface reflectance (SR) sensitive to woody AGB was firstly selected and interannual time-series of composited SR was smoothed using S-G filter for each pixel, and then optimal machine learning algorithm was selected to estimate woody AGB time-series. Pixels that have reached AGB potential were detected based on the AGB changing trajectory, and the potential was spatial-temporal extended using random forest model combining environmental variables under current climate condition and CMIP6 climate models. Results show that: 1) minimum value composite based on NIRv during Jul.-Sep. is more capable of explaining woody AGB variation in dryland (R = 0.87, p < 0.01), and Random Forest (RF) model has the best performance in estimating woody AGB (R2 = 0.75, RMSE = 4.74 t·ha−1) among sis commonly used machine learning models. 2) Annual woody AGB estimates can be perfectly fitted with a logistic growth curve (R2 = 0.97, p < 0.001) indicating explicit growth regularity of woody vegetation, which provides physiological foundation for determining woody AGB potential. 3) Woody AGB potential can be accurately simulated by RF combining environmental variables (R2 = 0.95, RMSE = 2.89 t·ha−1), and current woody AGB still has a potential of small increase, whereas the overall losses of woody AGB potential were observed in 2030, 2040 and 2050 under CMIP6 SSP-RCP scenarios.

Global source apportionment of aerosols into major emission regions and sectors over 1850–2017

Abstract. Anthropogenic emissions of aerosols and precursor gases have changed significantly in the past few decades around the world. In this study, the Explicit Aerosol Source Tagging (EAST) system is merged into the Energy Exascale Earth System Model version 1 (E3SMv1) to quantify the variations in anthropogenic aerosol concentrations, source contributions, and their subsequent radiative impact in four major emission regions across the globe during 1850–1980, 1980–2010, and 2010–2017. In North America and Europe, changes in anthropogenic PM2.5 were mainly caused by changes in emissions from local energy and industrial sectors. The local industrial sector caused the largest increase in PM2.5 in East Asia during 1980–2010 and decrease during 2010–2017. In South Asia, the increase in energy-related emissions dominated the rise in PM2.5 levels during 1980–2017. During 1850–1980, the increases in emissions from North America contributed to the increase in the European PM2.5 burden by 1.7 mg m−2 and the sources from the Europe were also responsible for the PM2.5 burden increase in East Asia and South Asia by about 1.0 mg m−2. During 1980–2010, East Asia contributed to an increase of 0.4–0.6 mg m−2 in the PM2.5 burden in North America and Europe, while South Asia contributed about 0.3 mg m−2. During 2010–2017, the contributions from East Asia to the PM2.5 burdens in the North America, Europe, and South Asia declined by 0.3–0.6 mg m−2 due to the clean air actions in China, while the contributions from South Asia still increased due to the continuous increase in emissions in South Asia. The historical changes in aerosols had an impact on effective radiative forcing through aerosol–radiation interactions (ERFari). During 1980–2010, a decline in North American aerosols resulted in a positive ERFari change (warming effect) in Europe and a decline in aerosols in Europe caused a warming effect in Russia and northern China. The changes in ERFari from the increase and decrease in aerosols in China during 1980–2010 and 2010–2017, respectively, are comparable in magnitude. The continuous aerosol increases in South Asia from 1980 to 2017 resulted in negative ERFari (cooling) changes in South Asia, Southeast Asia, and southern China.

Temporal changes in geographic range and population size of the Santa Cruz Black Salamander

Abstract The Santa Cruz Black Salamander Aneides niger is a priority 3 California species of special concern with a restricted geographic range confined to the Santa Cruz Mountains. Anecdotal observations suggest that the species was relatively abundant in the early 1900’s, but it has become more difficult to find in the past few decades. To better understand if the species has undergone population size fluctuations, we analyzed mitochondrial and nuclear sequence data to examine levels of genetic variation, phylogeographic structure, and test for signatures of population size change. We then reconstructed the climatic suitability for the species to A) determine if past climate fluctuations could have influenced range size and genetic diversity, and B) to estimate the effects of future climate change on geographic range suitability as a proxy for possible future population size change. Genetic analyses detected low levels of genetic variation and a general lack of genetic structuring, suggesting a recent genetic bottleneck. While neutrality tests of individual loci were non-significant, skyline plot and isolation-with-migration analyses detected a relatively recent reduction in population size. These genetic results should be interpreted with consideration of the limited number of localities and individuals that have been sampled for this species. Climatic suitability for Santa Cruz Black Salamanders was much lower during the last glacial maximum, which could be the cause of the detected historical change in population size. Future projections of climatic suitability under a high emission scenario suggest a dramatic geographic range restriction to coastal areas. These projections highlight the need for the protection of coastal habitat patches to preserve existing coastal populations, and to maintain connectivity between coastal and inland habitats to allow the westward movement of populations and genes in response to climate change.

Embracing the digital landscape: enriching the concept of sense of place in the digital age

In unraveling the profound connections between humans and place, the traditional concept of the sense of place takes on new dimensions in the digital era. This study contributes to a nuanced understanding by integrating digital and physical spaces within the context of information and communication technology (ICT). Beginning with a review of historical changes and debates surrounding the sense of place, the research establishes a foundation for understanding the evolving relationship with the place. Building on this, the study explores the intricate interplay between digital media and place, revealing how advancements in digital technology shape perceptions of the sense of place. Beyond analysis, the study introduces a three-dimensional framework for the sense of place (i.e., physical sense of place, digital sense of place, and hybrid sense of place), recognizing the dynamic relationship between individuals and their environment, incorporating the digital dimension. Firmly grounded in the perspective of relationships, this framework captures multifaceted connections individuals establish with both physical and digital spaces. Finally, the research explores practical applications of this reconceptualized sense of place. This research deepens the current understanding of the complex dynamics in constructing places in contemporary society, where digital and physical realms intertwine. This research serves as a crucial steppingstone for comprehending the evolving dynamics of the sense of place in the digital era, presenting a refined framework that captures the complex relationships between individuals, technology, and the places they inhabit.

The evolution of artistic conflict in the work of V.S. Makanin

The subject of the study is the artistic conflict in the works of V. S. Makanin. The object of the study is the evolution of this conflict during various periods of the writer's work. The author examines in detail such aspects of the topic as the impact of social and historical changes on the structure and content of artistic conflict. Special attention is paid to the analysis of three key stages in the development of the conflict: the period of the Soviet era, the time of social reforms and the modern stage of the integration of Russian literature into the world literary context. The main thematic and stylistic changes that took place in literature in response to social and cultural transformations are analyzed. The research is of interest for a deep understanding of the specifics of Russian literature of the late XX – early XXI century, as well as for studying the interrelationships of the literary process with historical and social changes in the country. The research methodology includes a morphological analysis of the structure of Makanin's works, stylistic analysis as a culture-specific code of the author, and a modeling method for predicting literary trends and creating variations of texts. The main conclusions of the conducted research are the identification and analysis of the three-stage development of artistic conflict in the works of V. S. Makanin. The first stage reflects the transformation of Soviet and Russian society, the second – the spread of social tolerance in the last years of the USSR, and the third – the modernization and integration of Russia into world culture since 1991.The author's special contribution to the research of the topic is an in-depth analysis of the changes in artistic conflict in the context of sociocultural transformations of society. The study shows how external social and cultural changes affect the inner world of characters and the structure of literary texts. The novelty of the research lies in a multidimensional approach to the analysis of artistic conflict, which allows not only to consider it within the framework of a literary structure, but also to reflect a wide range of relationships between a literary work and changes in society over various historical periods. This allows us to better understand the mechanisms of interaction between literature and society, as well as to evaluate the individual contribution of the writer to the reflection and interpretation of these changes through the prism of artistic conflict.

Thoughts on and Proposal for the Education, Training, and Recruitment of Infectious Disease Specialists.

The global pandemic of COVID-19 has underscored the significance of establishing and sustaining a practical and efficient infection control system for the benefit and welfare of society. Infectious disease (ID) specialists are expected to take on leadership roles in enhancing organizational infrastructures for infection prevention and control (IPC) at the hospital, community, and national levels. However, due to an absolute shortage and an uneven distribution, many core hospitals currently lack the ID specialists. Given the escalating global risk of emerging and re-emerging infectious diseases as well as antimicrobial resistance pathogens, the education and training of ID specialists constitutes an imperative concern. As demonstrated by historical changes in the healthcare reimbursement system, the establishment and enhancement of IPC measures is pivotal to ensuring medical safety. The existing structure of academic society-driven certification and training initiatives for ID specialists, contingent upon the discretionary decisions of individual physicians, possesses both quantitative and qualitative shortcomings. In this article, I first address the present situations and challenges related to ID specialists and then introduce my idea of securing ID specialists based on the new concepts and platforms; (i) ID Specialists as National Credentials, (ii) Establishment of the Department of Infectious Diseases in Medical and Graduate Schools, (iii) Endowed ID Educative Courses Funded by Local Government and Pharmaceutical Companies, and (iv) Recruitment of Young Physicians Engaged in Healthcare Services in Remote Areas. As clarified by the COVID-19 pandemic, ID specialists play a crucial role in safeguarding public health. Hopefully, this article will advance the discussion and organizational reform for the education and training of ID specialists.

The Essential Role of Local Context in Shaping Risk and Risk Reduction Strategies for Snowmelt‐Dependent Irrigated Agriculture

AbstractClimate change‐induced shifts in snow storage and snowmelt patterns pose risks for adverse impacts to people, the environment, and irrigated agriculture. Existing research primarily focuses on evaluating these risks to irrigated agriculture at large scales, overlooking the role of local context in shaping risk dynamics. Consequently, many “at‐risk” areas lack insight into how adaptation strategies for managing risk through water supply augmentation or water conservation vary across contexts and over time. To address this gap, we develop a comprehensive index for evaluating irrigated agriculture's risk and adaptation potential to changes in snow at local scales and apply it throughout the western US. Results confirm trends toward escalating risk for changes in snow storage and snowmelt patterns over the century. However, substantial heterogeneity in the extent and drivers of risk exists due to variability in localized interactions between declines in water supply (approximately −9% ± 13% by 2100) and increased agricultural demand (approximately 7% ± 5% by 2100). Despite an existing focus on supply augmentation as a critical adaptation strategy to reduce risk, we show its effectiveness diminishes for many areas over time, declining to an average of −54% of historical augmentation potential by 2100. Conserving water through historical changes in crop acreage and type emerges as a more stable adaptation measure, reducing demand by 7%–8% regardless of time. While particularly relevant for higher elevation, less intensive agricultural settings in snowmelt‐dependent regions, findings underscore the need for strategies that support local‐scale, context‐appropriate adaptation to effectively manage escalating risk as snow changes.

National Population Growth Rate, Its Components, and Subnational Contributions: A Research Note.

A population's current growth rate is determined jointly by changes in fertility, mortality, and migration. This overall growth rate is also the average of age-specific growth rates, which can be decomposed into the result of historical changes in fertility, mortality, and migration. However, doing so requires more than 100 years of historical data, meaning that such analyses are possible only in a select few populations. In this research note, we propose an adapted version of the variable-r model to measure contributions to the population growth rate for countries with shorter demographic series. In addition, we extend this model to explore the contribution of subnational changes to the national population growth rate. Our results demonstrate that the age-specific growth rates obtained from short historical series, say 25 years, closely match those of the longer series. These abbreviated age-specific growth rates closely resemble the growth rate at birth of their respective cohorts, which is the major determinant of population growth, except at older ages where mortality becomes the main explanatory element. Exploring subnational populations, we find considerable heterogeneity in the age profile of the components of growth and find that the most populous regions tend to have an outsized impact on national-level growth.

Historical change in trajectories of loneliness in old age: Older adults today are less lonely, but do not differ in their age trajectories.

To check claims of a "loneliness epidemic," we examined whether current cohorts of older adults report higher levels and/or steeper age-related increases in loneliness than earlier-born peers. Specifically, we used 1,068 age-matched longitudinal reports (Mage observations = 79 years, 49% women) of loneliness provided by independent samples recruited in the German city of Berlin in 1990 and 2010, n = 257 participants in the Berlin Aging Study (BASE) and n = 383 participants in Berlin Aging Study II (BASE-II). Using multilevel models that orthogonalize between-person and within-person age effects, we examined how responses to items from the UCLA Loneliness Scale provided by observation-matched cohorts differed with age and across cohorts, and if those differences might be explained by a variety of individual factors. Results revealed that at age 79, the later-born BASE-II cohort reported substantially lower levels of loneliness than the earlier-born BASE cohort (d = -0.84), with cohort differences accounting for more than 14% of the variance in loneliness. Age trajectories, however, were parallel without evidence of cohort differences in rates of within-person age-related changes in loneliness. Differences in gender, education, cognitive functioning, and external control beliefs accounted for the lion's share of cohort-related differences in levels of loneliness. Results show that loneliness among older adults has shifted to markedly lower levels today, but the rate at which loneliness increases with age proceeds similarly as 2 decades ago. Future studies should investigate how psychosocial functioning across the life course is progressing in different sociohistorical contexts and in other age groups, such as younger and middle-aged adults.

The impacts of land use change on partridge’s population in the Marghazar valley of Swat District, Pakistan

Abstract In landscape ecology, it has become increasingly essential to understand the consequences of past, current, and future human land use patterns for biodiversity and ecosystem function. The most significant factor affecting biodiversity loss is land-use and land-cover change (LULCC). We examine here the impact of long-term changes in LULCC from 2000–2020 on the biodiversity of Marghazar valley in Swat District. Information was also gathered on the perceptions of the surrounding communities based on the flow of ecosystem services (ES), historical changes, and the causes of those changes. Satellite imagery data were used to map LULCC, identify possible causes, and assess the impact of LULCC on the population of partridges. In the last 20 years, forest area has reduced by 23 km2 (33%) and the seasonal water body has declined by 1.015 km2 (2.15%). There was a 38.5 km2 decrease in agricultural land. In contrast, the built-up area increased by 384%, resulting in a total growth of 26.3 km2 and an expansion of 41.1 km2 grassland. Deforestation, agricultural expansions, urbanization, economic considerations and changes in land tenure policy were identified to be the main drivers of LULCC. The primary impact of LULCC on partridges in the studied area are land degradation, population declines, habitat disruption, displacement of partridges by livestock and increasing human-wildlife conflicts. Despite ongoing human pressure, the Marghazar valley still provides extensive habitat for wildlife. Interventions may be needed to maintain biodiversity and ensure long-term ecological services in the area.

Local and Nonlocal Biophysical Effects of Historical Land Use and Land Cover Changes in CMIP6 Models and the Intermodel Uncertainty

AbstractLand use and land cover changes (LULCCs) can influence surface temperature through local and nonlocal biophysical processes, which remain inadequately addressed. In this study, we separate the local and nonlocal effects of historical (1850–2014) LULCCs based on model outputs from the Coupled Model Intercomparison Project Phase 6. We also attempt to explore the sources of intermodel differences in the effects of LULCCs. The multimodel mean shows a cooling effect of −0.05°C (with an intermodel range of −0.24–0.06°C) at the global scale due to cropland and pastureland expansion, consisting of dominant nonlocal cooling of −0.06°C (with an intermodel range of −0.26–0.06°C) and slight local warming of 0.01°C (with an intermodel range of −0.01–0.05°C). The modeling results show some clear consistency in the effects of LULCCs despite considerable intermodel uncertainties. The local effects cause warming at low latitudes and cooling in boreal regions via changes in upward shortwave radiation and sensible and latent heat fluxes. The nonlocal effects mainly cause cooling via decreases in downward longwave radiation and increases in upward shortwave radiation. Intermodel differences in the total effects are dominated by those in the nonlocal effects, which are further attributed to divergent changes in downward longwave radiation and sensible heat flux across the models. This study highlights the importance of the nonlocal effects of LULCCs in terms of strength and intermodel uncertainty, with implications for designing land‐based solutions aimed at climate change mitigation.

An invisible heritage. Company books and "bookhood" in the Italian case

This contribution sets out to frame the phenomenon of company books and its con- temporary evolution in Italy in the context of corporate publishing and communication. Corporate history books, biographies and other kinds of editions are promoted by organizations to preserve and communicate their own corporate history, identity and heritage to stakeholders. Despite representing a distinctive and long-standing pub- lishing genre, corporate monographs remain a singular case of "books-no books" affected by a fundamental inattention and prejudice about their literary and docu- mentary quality. The historic and contemporary profiles of this sector are retraced and compared through a focused review of several field studies and literary "classics" concerning the Italian case. Indeed, books stand among the most refined, highly performing but also most complex media to be used, in absolute terms, by companies and profes- sionals, who are being called upon to rediscover and learn how to drive such a pow- erful technology of communication, one that has a long life ahead of it yet.

The Contemporary Transformation of Thematic Connotation and Narrative Mode of Peking Opera from The Jewelry Purse

Artistic creation in any era reflects the collective consciousness in the context of the era in which it is created. From the late Qing Dynasty to the Republic of China, Peking Opera has completed its transformation as a systematic performing art in the course of historical changes, while retaining its unique cultural heritage and traditional performance forms. This paper adopts the typical text The Jewelry Purse as the research subject in the review of the history of Peking Opera, conducts an in-depth analysis of the development of Peking Opera. By deconstructing the text of The Jewelry Purse, refines the modernity of The Jewelry Purse as evidence for discussing the changes in the modernity of Peking Opera in terms of themes and narrative modes. Peking Opera intensifies the reflection on the real situation by reinforcing the gap between the ideal and real society in its development process. As one of the excellent examples of Peking Operas self-renewal and transcendence, The Jewelry Purse can be created and expressed through the creators and performers realization of the reality in which they live, and resonate with audiences of different times.

Regional uniqueness of tree species composition and response to forest loss and climate change

The conservation and restoration of forest ecosystems require detailed knowledge of the native plant compositions. Here, we map global forest tree composition and assess the impacts of historical forest cover loss and climate change on trees. The global occupancy of 10,590 tree species reveals complex taxonomic and phylogenetic gradients determining a local signature of tree lineage assembly. Species occupancy analyses indicate that historical forest loss has significantly restricted the potential suitable range of tree species in all forest biomes. Nevertheless, tropical moist and boreal forest biomes display the lowest level of range restriction and harbor extremely large ranged tree species, albeit with a stark contrast in richness and composition. Climate change simulations indicate that forest biomes are projected to differ in their response to climate change, with the highest predicted species loss in tropical dry and Mediterranean ecoregions. Our findings highlight the need for preserving the remaining large forest biomes while regenerating degraded forests in a way that provides resilience against climate change.
