The origin and morphological character evolution of the paleotropical woody bamboos.

The woody bamboos (Bambusoideae) exhibit distinctive biological traits within Poaceae, such as highly lignified culms, rapid shoot growth, monocarpic mass flowering and nutlike or fleshy caryopses. Much of the remarkable morphological diversity across the subfamily exists within a single hexaploid clade, the paleotropical woody bamboos (PWB), making it ideal to investigate the factors underlying morphological evolution in woody bamboos. However, the origin and biogeographical history of PWB remain elusive, as does the effect of environmental factors on the evolution of their morphological characters. We generated a robust and time-calibrated phylogeny of PWB using single nucleotide polymorphisms retrieved from optimized double digest restriction site associated DNA sequencing, and explored the evolutionary trends of habit, inflorescence, and caryopsis type in relation to environmental factors including climate, soil, and topography. We inferred that the PWB started to diversify across the Oligocene-Miocene boundary and formed four major clades, that is, Melocanninae, Racemobambosinae s.l. (comprising Dinochloinae, Greslanlinae, Racemobambosinae s.str. and Temburongiinae), Hickeliinae and Bambusinae s.l. (comprising Bambusinae s.str. plus Holttumochloinae). The ancestor of PWB was reconstructed as having erect habit, indeterminate inflorescence and basic caryopsis. The characters including climbing/scrambling habit, determinate inflorescence, and nucoid/bacoid caryopsis have since undergone multiple changes and reversals during the diversification of PWB. The evolution of all three traits was correlated with, and hence likely influenced by, aspects of climate, topography, and soil, with climate factors most strongly correlated with morphological traits, and soil factors least so. However, topography had more influence than climate or soil on the evolution of erect habit, whereas both factors had greater effect on the evolution of bacoid caryopsis than did soil. Our results provide novel insights into morphological diversity and adaptive evolution in bamboos for future ecological and evolutionary research.

The analysis of evolutionary strategies to facilitate the transformation of traditional buildings into prefabricated buildings

This paper establishes a two-party evolutionary game theory model comprising of the governments and prefabricated components suppliers as the players; and uses the replicator dynamic equations to analyze the evolution mechanisms each player’s strategy choices. Results from numerical simulations indicate that the evolution trajectory of the model is significantly influenced by not only the initial strategies of the players, but also by government incentives and regulatory penalties, as well as the costs and benefits resulted from each strategy choice. Also, prefabricated components suppliers exhibit greater responsiveness to variations in cost-related factors. When the subsidy and penalty respectively remain constant at 15% and 5% of the additional cost, the model exhibits both rapid and stable evolutionary trend towards the optimal evolutionarily stable strategy of full cooperation between the two players. This article proposes a suitable threshold for government incentives and penalties, besides serving as a guide for the steady and sustainable growth of the prefabricated buildings sector.

Evolutionary palaeoecology of European rhinocerotids across the Oligocene-Miocene transition.

The Oligocene-Miocene transition witnessed great environmental and faunal changes, spanning from late Oligocene to early Miocene (MP28-MN3). Its drivers and consequences on mammals are, however, poorly understood. Rhinocerotoids are among the most affected taxa, reflected by great taxonomical and morphological changes. However, potential associated changes in ecology have not been explored. Here, we investigated the palaeoecology of 10 rhinocerotid species coming from 15 localities across Western Europe and ranging from MP28 to MN3. We explored evolutionary trends for diet, physiology and habitat via dental wear, hypoplasia, body mass and stable isotopy. All rhinocerotids studied were C3 feeders, whether browsing or mixed-feeding, but clear dietary differences were observed at some localities and between Oligocene and Miocene rhinocerotids. The prevalence of hypoplasia was low (less than 10%) to moderate (less than 20%), but there were great differences by loci, species and localities. Body mass covaried with hypoplasia prevalence, suggesting that larger species might be more susceptible to stresses and environmental changes. We reconstructed similar warm conditions at all localities except Gaimersheim, but found greater variations in precipitation. Indeed, a clear shift in δ13C values was noticed at the end of the Oligocene, consistent with climatic and vegetation changes reported at that time.

Business Cycle Dynamics in the Romanian Economy: Phases and Developments

Romania's economy is not yet sufficient / complete and competitive connected to the developed European economy and the global one. In recent economic and general political history, the political, institutional and economic changes that have taken place since 1990 in Central and Eastern Europe, including Romania, are already recognized. The article deals with the evolutionary situational stages towards the New Economy of Romania. It also describes the post-transformation horizon for achieving quasi-constant inverted levels between “tangible-intangible” for the transition to a new business cycle in the New Knowledge-Based Economy and Risk. It follows that if GDP reflects the sum of the market value of all goods and services intended for final consumption, not intermediate ones, produced in all branches of the economy within Romania within a year, by way of investigative proximity, business and cycles of manifestation of these were closely followed by dimensional evolutionary trends of similarity and aggregation with GDP. In fact, the New Knowledge-Based Economy has radically and positively changed Romania's advance towards the digitalized society, based more and more on the operationalization of intangible assets. The problem of vision, strategy and development tactics through new business cycles is found in the search for the optimal structural ratio between tangible and intangible assets (knowledge) insurers for competitiveness and sustainability.

Radiolarians from Cambrian Series 2 Niujiaohe Formation in southern Jiangxi, South China

The origin and early evolution of radiolarian fossils have always provoked great interest among paleontologists. Yet, little is known about the earliest morphological and evolutionary characteristics of radiolarians largely due to the lack of documentation of early Cambrian radiolarian fossils. Herein, we conduct a thorough examination of the basinal Niujiaohe Formation in Chongyi County of southern Jiangxi and report two types of radiolarians: a large number of spherical radiolarians and a minor occurrence of ellipsoidal radiolarian fossils with bipolar rodded spines. The lengths of the spines on ellipsoid radiolarian fossils vary, and typically, the main spines are slightly offset from the polar axis, resulting in an asymmetrical appearance in some specimens. Through systematic taxonomic examination, this radiolarian fossil form is tentatively identified as Beothuka sp. of the spherical polycystine group. The genus Beothuka is commonly found in the Early Ordovician and has not yet been reported in the early Cambrian. Combined with previous reports, four species of radiolarians in three genera are identified from the Niujiaohe Formation in South China, including Paraantygopora porosa, Paraantygopora sp., spherical radiolarian, and Beothuka sp. Overall, the radiolarian fossils in the Niujiaohe Formation are characterized by low diversity and small size, in contrast to the relatively more diverse fauna found in the contemporary shallow-water Shuijingtuo Formation. Therefore, we speculate that radiolarians may have initially originated in shallow water areas and gradually expanded to deep water. This study further enriches the fossil record of the Cambrian Series 2 radiolarians. Combined with relevant data from South China, the radiolarian fauna began to exhibit diversity and complex morphology, indicating the presence of various, advanced spherical-skeletons in early radiolarians, and radiolarians from the early Cambrian appeared to display multiple evolutionary trends.

Tendance Evolutive Et Bilan Des Sediments De Profondeur De 2008 A 2018 : Cas De La Lagune Adjin (Littoral De La Cote D’ivoire)

The Adjin lagoon was studied in its morphological, hydrological and sedimentological aspect. This study made it possible to understand the morphological modifications of the bottom and surface of the Adjin lagoon based on the production and superposition of two bathymetric maps from the years 2008 and 2018. In addition, this study makes it possible to know the estimation of the speed, volume of sediments eroded and deposited. From a morphological point of view, the Adjin lagoon is characterized by depressions and shoals. The depressions are at the origin of the formation of “V” shaped channels. Shoals are characteristic of “U” shaped channels. Depths less than 11 m occupy 2/3 of its surface area. Particularly during the last ten years, the Adjin lagoon has suffered erosion and deposition phenomena. The rate of eroded sediments is estimated at approximately - 1.65 hm³ over an area of 7.9 km2 while in the same period, the rate of sediments deposited is +3.42 hm³ over an area of 12.3 km2 . This results in a sediment budget of +1.77 hm³. The evolutionary trend of sedimentary dynamics in the Adjin lagoon is therefore more favorable to fattening than to erosion. The sedimentation rate is estimated at approximately 2.7 cm/year. The morphological analysis and the sedimentary balance provide crucial information on the good management of fresh water and aquatic resources of the Adjin lagoon. Therefore, populations living near this body of water must limit their domestic activities in order to preserve the quality of this water

Paleobiology and paleoecology of the woolly rhinoceros (Coelodonta antiquitatis) in Northern and Central Europe: New insights from multi-proxy data

The woolly rhinoceros, Coelodonta antiquitatis, was an emblematic component of Pleistocene faunas in Eurasia, which went extinct around ca. 12.5 ky BP. The loss of its tundra-steppe habitat due to climatic changes is considered the main cause for its extinction, whereas human impact was limited. In this study, we investigated the paleobiology and paleoecology of C. antiquitatis during the last glacial interval (Würm/Weichselian; 130 to 11.7 kya). We explored evolutionary trends for diet, physiology, and habitat via dental wear, enamel hypoplasia, body mass, age structure, mortality curves and stable isotopes (carbon and oxygen). Our results confirmed that C. antiquitatis was a large-sized species, with body mass around 2000–2500 kg, and with C3 grazing or mixed-feeding habits. Age structure and mortality curves revealed potential sampling and/or taphonomical biases at a few localities (e.g., Brixham cave, Ofnethöhle, North Sea), and indicated several vulnerability periods (birth, weaning, cow-calf separation/maturity) also retrieved by hypoplasia analyses. We observed some spatio-temporal fluctuations of body mass (1850–2955 kg), dietary preferences (strict to variable grazing) and hypoplasia prevalence (7.41–47.06 %) of C. antiquitatis depending on the locality, but correlation to specific climatic events (stadials-interstadials) is difficult without exact datation. These variations were however limited, highlighting a rather strict climatic niche and suggesting a high vulnerability to climatic and vegetation changes.

Digital Economy and Urban Innovation Ability: From the Spatial Nonlinear Perspective

Using the panel data of China’s 286 prefecture-level cities from 2011 to 2019, this paper explores the causal relationship between digital economy and urban innovation ability by panel vector auto-regression (PVAR), examines the spatial and dynamic effects of digital economy on urban innovation ability by spatial dynamic panel Durbin (SDPD) model, and studies the nonlinear effects of digital economy on urban innovation ability under different external environments using threshold spatial dynamic panel (TSDP) model. The results show that: (a) The urban innovation ability has significant spatial dependence and presents a U-shaped evolution trend. (b) In the short term, the digital economy has a positive impact on urban innovation ability, both directly and indirectly; in the long term, only the indirect effect of the digital economy remains significantly positive. (c) In different external environments, the impact of digital economy on urban innovation ability is nonlinear and has significant external environmental threshold characteristics. Specifically, the digital economy is more conducive to the improvement of urban innovation ability with a moderate degree of marketization; the effect of digital economy empowering urban innovation ability is better in a good legal environment or technological environment.

Evolution of dielectric properties of SiBCN ceramics and its derived wireless passive temperature sensor application

SiBCN ceramics derived from preceramic polymers are suitable candidates for high-temperature sensors due to their remarkable high-temperature stability and semiconducting properties. However, research into their dielectric performance together with relevant sensors is meaningful but inadequate. In this work, the correlation between dielectric properties and the structure of SiBCN ceramic is identified by studying the evolution trend of the chemical composition, microstructure, and dielectric properties with pyrolysis and environment temperature. SiBCN ceramic was prepared by powder pressing process and pyrolyzed at 1000–1400 °C. As the pyrolysis temperature increased, the dielectric constant and dielectric loss tangent of SiBCN ceramic gradually increased. Within the test temperature range of 500 °C, the dielectric loss was mainly polarization loss. In addition, SiBCN ceramic wireless passive temperature sensors were prepared to test their performance from room temperature to 500 °C. The results showed that the sensitivity increased with the test temperature, and the transmission efficiency of the sensor was closely related to the dielectric properties, indicating that SiBCN ceramic has promising application prospects in the field of high-temperature sensing with good repeatability and stability.

Genetic polymorphism of Duffy binding protein in Pakistan Plasmodium vivax isolates

Plasmodium vivax Duffy binding protein (PvDBP) is crucial for erythrocyte invasion, interacting with the Duffy Antigen Receptor for Chemokines (DARC) on the erythrocyte surface. The amino-terminal cysteine-rich region II of PvDBP (PvDBPII) is a promising blood stage vaccine candidate, yet the genetic polymorphisms of this protein in global P. vivax isolates complicate the design of effective vaccines against vivax malaria. This study analyzed the genetic polymorphism of PvDBPII in Pakistan P. vivax isolates. A total of 29 single nucleotide polymorphisms (SNPs), including 22 nonsynonymous SNPs, were identified in 118 Pakistan PvDBPII. Most amino acid substitutions occurred in subdomains II and III, with six commonly observed in the global PvDBPII population. The amino acid change patterns in Pakistan PvDBPII generally mirrored those in global PvDBPII, although the frequencies of amino acid changes varied by country. Nucleotide diversity in Pakistan PvDBPII was comparable to that found in global PvDBPII. Evidence of natural selection and recombination in Pakistan PvDBPII aligned with observations in global PvDBPII. Analysis of the haplotype network of global PvDBPII revealed a complexed network of 167 haplotypes, but no geographical clustering was observed. The findings are crucial for understanding the genetic characteristics of Pakistan PvDBPII. A comprehensive analysis of nucleotide diversity and evolutionary trends in the global PvDBPII population offers valuable insights for the development of vivax malaria vaccines based on this antigen.

Comparative morphology and anatomy of Korean Boehmeria achenes and their taxonomic significance

This study confirmed the taxonomic significance of achenes by observing and comparing the morphology and anatomical characteristics of 13 taxa of the genus Boehmeria in Korea. The results confirmed that the achenes studied here are the drupe-like fruit type with mucilage in the exocarp, and during the fruiting season, the perianth persists on the pericarp. The morphological characteristics of the achenes, specifically the number per glomerule as well as the size, shape, color, and trichome were taxonomically significant. The anatomical characteristics of the transverse sectional shape and wings, the thickness of each pericarp layer, the shape of the crystalliferous cells in the mesocarp, and the number of sclereid cell layers in the endocarp were also found to be important. Particularly, the size and wings of the achenes were informative for distinguishing between Sect. Tilocnide and Sect. Duretia, while other characteristics were differentiated among series or certain taxa within the series. The taxonomic significance of the achenes is discussed through comparisons with previously studied taxa and their characteristics. Accordingly, the results of this study can provide valuable insight for those seeking to understand the evolutionary trends of achenes in Boehmeria in the future.

Evolution of aromatic amino acid metabolism in plants: a key driving force behind plant chemical diversity in aromatic natural products.

A diverse array of plant aromatic compounds contributes to the tremendous chemical diversity in the plant kingdom that cannot be seen in microbes or animals. Such chemodiversity of aromatic natural products has emerged, occasionally in a lineage-specific manner, to adopt to challenging environmental niches, as various aromatic specialized metabolites play indispensable roles in plant development and stress responses (e.g. lignin, phytohormones, pigments and defence compounds). These aromatic natural products are synthesized from aromatic amino acids (AAAs), l-tyrosine, l-phenylalanine and l-tryptophan. While amino acid metabolism is generally assumed to be conserved between animals, microbes and plants, recent phylogenomic, biochemical and metabolomic studies have revealed the diversity of the AAA metabolism that supports efficient carbon allocation to downstream biosynthetic pathways of AAA-derived metabolites in plants. This review showcases the intra- and inter-kingdom diversification and origin of committed enzymes involved in plant AAA biosynthesis and catabolism and their potential application as genetic tools for plant metabolic engineering. I also discuss evolutionary trends in the diversification of plant AAA metabolism that expands the chemical diversity of AAA-derived aromatic natural products in plants. This article is part of the theme issue 'The evolution of plant metabolism'.

Development of Bone Marrow Transplantation Strategies

The use of alternative stem cell sources, the growth of supportive healthcare facilities, and the expansion of indications for bone marrow transplantation (BMT) as well as partially matched donors from the same family are all continuing evolutionary trends as the use of BMT has been developed and expanded to include donors who are not related by blood but have Partial histocompatibility antigen compatibility. Although the outcomes of these transplants are not as good as those performed with first-degree siblings, patients with leukemia, aplastic anemia, and immunodeficiency disorders who cannot receive treatment otherwise they can receive it now. Patients suffering from diseases such as acute myeloid leukemia, acute lymphoblastic leukemia, and Hodgkin lymphoma also show success with autologous bone marrow transplants. Furthermore, bone marrow or blood stem cell support is used after intensive chemotherapy. Patients with stage II, III, and IV breast cancer can benefit from treatment with bone marrow cells found in peripheral blood. In this review, the most important developments in autologous and allogeneic bone marrow transplantation, the control of infectious diseases, and the use of gene therapy to alter genetic disorders that are transmitted from parents to their offspring through bone marrow or peripheral blood infusions are outlined.

A Strategic Study on the Planning of Accommodation Facilities in Tourist Attractions to Enhance Tourist Experience

In the context of the development of regional tourism, the planning pattern of accommodation facilities in tourist attractions plays a very important role in enhancing tourists’ experience perception, which is conducive to the enhancement of tourists’ goodwill towards tourist attractions. This paper is oriented to the theory of sustainable development, and selects GL city as the research case site to obtain the visitor evaluation data of accommodation facilities in tourist attractions. The evolution trend of tourist attraction accommodation facilities is analyzed by geographic concentration index, standard deviation ellipse, nearest neighbor index, combined with TF-IDF algorithm to extract high-frequency words of tourists’ experience on the planning of tourist attraction accommodation facilities, and coarse-grained tourism review text sentiment classification model is introduced to analyze the tourists’ sentiment evaluation of tourist attraction accommodation facilities. The geographic concentration index of accommodation facilities in tourist attractions increases from 20.19 to 53.72 from 1980 to 2023, and the relative frequency difference between “service” and “room” of hotel facilities in tourist attractions is 4.35 percentage points, while that of B&B is only 0.5 percentage points. The relative frequency of “service” and “room” of hotel facilities in tourist attractions differed by 4.35 percentage points, while that of B&Bs differed by only 0.77 percentage points, and more than 70% of the tourists had a positive attitude towards the experience of accommodation facilities in tourist attractions. Lodging facilities in tourist attractions need to enrich the sequence of lodging products, improve the layout of service and reception facilities, create relevant themed B&Bs, and enhance the service quality of lodging facilities by combining modern technology to further promote the sustainable development of lodging facilities planning.

Differential Evaluation of Ecological Resilience in 45 Cities along the Yangtze River in China: A New Multidimensional Analysis Framework

The rapid pace of urbanization and global climate change necessitates a thorough assessment of urban ecological resilience to cultivate sustainable regional ecosystem development. Cities along the Yangtze River face an intensifying conflict between ecological preservation and socio-economic growth. Analyzing the ecological resilience of these urban centers is essential for achieving equilibrium in regional urban ecosystems. This study proposes a “system process space” attribute analysis framework, taking into account urban development processes, ecosystem structure, and resilience evolution stages. Utilizing data from 45 Yangtze River cities, we establish a “Driver, Pressure, State, Impact, and Response” (DPSIR) evaluation index system to evaluate changes in ecological resilience levels and evolution trends from 2011 to 2022. Our findings indicate that: (1) The ecological resilience index of Yangtze River cities increased from 0.177 to 0.307 between 2011 and 2022, progressing through three phases: ecological resilience construction, rapid development, and stable development. (2) At the city level, ecological resilience along the Yangtze River exhibits uneven development characteristics. Upstream cities display a significant “stepped” pattern, midstream cities exhibit a significant “Matthew effect”, and downstream cities present a pyramid-shaped pattern. While regional differences in ecological resilience persist, overall polarization is gradually decreasing, intercity connections are strengthening, and there is a growing focus on coordinated regional development. (3) The spatial distribution of ecological resilience in Yangtze River cities demonstrates both continuity and evolution, generally forming a “core-edge” clustered pattern. Based on these findings, we recommend enhancing inter-city cooperation and connectivity, addressing imbalances in urban ecological resilience, and promoting high-quality ecological resilience development along the Yangtze River through tailored development strategies for each city.
