The Role of Social Conservatism and Family Vaues Regarding the Use of Pornography Among Romanians: A Moderated Mediation Model.

Objective: To develop the Pornography Problems Due to Moral Incongruence model by exploring social conservatism and family values regarding the use of pornography (FVUP). Method: 501 Romanian individuals, aged 18-76 (M = 22.77, SD = 9.29), 71.9% females. Results: Social conservatism and FVUP provide a significant additional explanatory power, explaining 22.9% of the variance in the initial model. Moreover, social conservatism mediated the relationship between FVUP and moral disapproval of pornography, while religiosity moderated the relationships between FVUP and moral disapproval of pornography and between FVUP and social conservatism. Conclusion: Social conservatism and FVUP significantly influence moral disapproval of pornography.

Role of national regime ideology for predicting biodiversity outcomes.

The rapid decline of global biodiversity has engendered renewed debate about the social, economic, and political factors contributing to it. Specifically, there is little understanding of the role that political ideology within a country (e.g., nationalism, conservatism, socialism) plays in determining biodiversity outcomes. We used negative binomial generalized linear models to investigate the importance of national regime ideology in predicting threatened animal species and protected area establishment compared with other factors that affect biodiversity outcomes, such as gross domestic product, inequality, and democracy. For threatened animals, the model with the highest Akaike weight suggested adverse biodiversity outcomes arose from larger gross domestic product (ß = 0.120, p < 0.001). However, nationalism (ß = 0.371, p < 0.01) and socialism (ß = 0.293, p < 0.05) were also significantly associated with increased proportions of threatened species. For protected areas, the model with the highest Akaike weight suggested increases in democracy (ß = 0.880, p < 0.001) led to a rise in relative protected area estate. Conservative regime ideology was also associated with greater protected area estate, although this did not increase the weight of evidence in support of the best models. These findings highlight the relevance of political ideology for predicting biodiversity outcomes at a national scale and illustrate opportunities to tailor policies and advocacy to promote biodiversity conservation more effectively. By targeting appropriate messaging and political advocacy, conservationists can improve the likelihood that politicians and their nations will participate in positive biodiversity actions.

El papel de la ideología del régimen nacional para la predicción de resultados de biodiversidad Resumen El rápido declive de la biodiversidad mundial ha suscitado un renovado debate sobre los factores sociales, económicos y políticos que contribuyen a él. En concreto, se conoce poco el papel que desempeña la ideología política dentro de un país (por ejemplo, el nacionalismo, el conservadurismo o el socialismo) a la hora de determinar los resultados en materia de biodiversidad. Utilizamos modelos lineales generalizados binomiales negativos para investigar la importancia de la ideología del régimen nacional a la hora de predecir las especies animales amenazadas y el establecimiento de áreas protegidas en comparación con otros factores que afectan a los resultados de la biodiversidad, como el producto interno bruto, la desigualdad y la democracia. En el caso de los animales amenazados, el modelo con la mayor ponderación de Akaike sugirió que los resultados adversos para la biodiversidad se debían a un mayor producto interno bruto (ß = 0,120, p < 0,001). Sin embargo, el nacionalismo (ß = 0,371, p < 0,01) y el socialismo (ß = 0,293, p < 0,05) también se asociaron significativamente con una mayor proporción de especies amenazadas. En el caso de las áreas protegidas, el modelo con la mayor ponderación de Akaike sugirió que el aumento de la democracia (ß = 0,880, p < 0,001) conducía a un aumento de la extensión relativa de las áreas protegidas. La ideología conservadora del régimen también se asoció con una mayor superficie de áreas protegidas, aunque no aumentó el peso de la evidencia en apoyo de los mejores modelos. Estos resultados resaltan la importancia de la ideología política para predecir los resultados de la biodiversidad a escala nacional e ilustran las oportunidades de adaptar las políticas y la defensa para promover la conservación de la biodiversidad de manera más eficaz. Si se orientan los mensajes y la promoción política de forma adecuada, los conservacionistas pueden mejorar la probabilidad de que los políticos y sus naciones participen en acciones positivas para la biodiversidad.

Differing worldviews: The politics of happiness, meaning, and psychological richness.

OBJECTIVE/BACKGROUND: Conservative ideology, broadly speaking, has been widely linked to greater happiness and meaning in life. Is that true of all forms of a good life? We examined whether a psychologically rich life is associated with political orientation, system justification, and Protestant work ethic, independent of two other traditional forms of a good life: a happy life and a meaningful life. METHOD: Participants completed a questionnaire that assessed conservative worldviews and three aspects of well-being (N = 583 in Study 1; N = 348 in Study 2; N = 436 in Study 3; N = 1,217 in Study 4; N = 2,176 in Study 5; N = 516 in Study 6). RESULTS: Happiness was associated with political conservatism and system justification, and meaning in life was associated with Protestant work ethic. In contrast, zero-order correlations showed that psychological richness was not associated with conservative worldviews. However, when happiness and meaning in life were included in multiple regression models, the nature of the association shifted: Psychological richness was consistently inversely associated with system justification and on average less political conservatism, suggesting that happiness and meaning in life were suppressor variables. CONCLUSIONS: These findings suggest that happiness and meaning in life are associated with conservative ideology, whereas psychological richness is not.

G-space versus E-space: Are hornets (Hymenoptera: Vespidae) at equilibrium with honeybees in Asia?

This study delves into the concept of niche conservatism (NC) and its implications for how hornets (Hymenoptera: Vespidae) and honeybees respond to climate change. Our primary objectives are threefold: firstly, to assess whether distinct environmental niche spaces (E-space) exist between 12 hornets and honeybees like Apis cerana and Apis mellifera in Asia; Secondly, to explore the degree to which Asian hornets have attained geographic equilibrium alongside honeybee species. Lastly, is to investigate how the geographic niche overlap (G-space) between hornets and honeybees could potentially change under climate change scenarios. To accomplish these goals, we employed ordination and ecological niche modeling techniques to analyze 91 pairs of hornets and honeybees in both geographic (G-space) and environmental (E-space) contexts. Then, we projected the potential impacts of climate change on the future geographic overlap between hornets and honeybees, specifically under the SSP585 climate scenario for the year 2070. Our results demonstrated that the environmental niches (E-space) of hornets and honeybees can be treated as interchangeable, indicating they have similar environmental preferences despite being unrelated taxa. We found that Vespa velutina currently exhibits a moderate geographic niche overlap (G-space) of 0.63 with both honeybee species. Meanwhile, Vespa mandarinia demonstrates an overlap of 0.46 with Apis cerana and 0.63 with Apis mellifera. The overlap of Vespa velutina with Apis cerana might potentially decrease to 0.51 and 0.56 with Apis mellifera. For Vespa mandarinia, the overlap could reach 0.41 with Apis cerana and 0.6 with Apis mellifera under a climate change scenario. This study indicates that the limited spatial overlap between honeybees and hornets across certain areas in Asia is more likely influenced by geographical barriers rather than solely environmental unsuitability for hornets. In this study, we delve into the concept of niche conservatism (NC) and its implications for how hornets (Hymenoptera: Vespidae) and honeybees respond to climate change.

The nexus of fertility and politics: exploring the influence of social tolerance, religiosity, and political conservatism on the acceptance of assisted reproduction in Spain.

STUDY QUESTION: How do individual religious, political, and social tolerance orientations influence the acceptance of ART among Spanish citizens? SUMMARY ANSWER: Social tolerance and religiosity are predictive factors for the acceptance of ART, with more tolerant individuals and those with lower levels of religiosity being more accepting of ART; political conservatism mediates the relationship between social tolerance and acceptance of ART, particularly for left-leaning individuals. WHAT IS KNOWN ALREADY: The rapid advancement of ART has raised questions about its societal acceptance, especially in the context of religious, political, and social beliefs. STUDY DESIGN, SIZE, DURATION: The analysis utilized data from the combined Europe Values Study and World Values Survey, comprising cross-sectional national surveys from 1981 to 2021. Each country's population was surveyed a maximum of seven times and a minimum of two times during this period. This study uses the cross-sectional data of 2021. After filtering for Spanish citizens and deleting cases with missing key variables, a sample of 1030 valid responses from Spanish citizens was obtained. Quotas were set for sex, age, and educational level, following guidance from the Spanish Statistics Institute. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study surveyed participants' attitudes towards ART, their religious and political orientations, and collected demographic information. The sample consisted of 51.7% women, most respondents were married or in common-law partnerships, and 61.6% had children. Catholicism was the dominant religion (53.0%) and a majority had completed secondary education (66.2%), with half earning over 1400 euros per month. MAIN RESULTS AND THE ROLE OF CHANCE: Using two linear models to test hypotheses, the study found that social tolerance and religiosity significantly predict acceptance of ART, with more tolerant and less religious individuals being more accepting. Political conservatism mediated the relationship between social tolerance and ART acceptance, particularly among left-leaning individuals. LIMITATIONS, REASONS FOR CAUTION: This study is cross-sectional and based on self-reported data, which may have limitations. Additionally, the findings are based on a Spanish sample and may not be universally applicable. WIDER IMPLICATIONS OF THE FINDINGS: The results have significant implications for policymakers and healthcare professionals in the field of reproductive technologies. They also contribute to public debates on ethical considerations surrounding ART. STUDY FUNDING/COMPETING INTEREST(S): This work was funded by the Mineco-FrontVida Program, Frontiers of Life, Social Change, and Changing Values Around the Beginning and End of Life (grant number PID2019-106882RB-I00), as part of the State Program for Knowledge Generation and Scientific and Technological Strengthening, and the State R&D Program Oriented to the Challenges of Society, 2019, Ministry of Science, Innovation, and Universities of Spain.

Ideological Rigidity and Political Conservatism in Relation to Death Anxiety and Reactions to Those With Different Beliefs.

This research tested the assumptions of Terror Management Theory (Pyszczynski et al., 2015) and conservatism as motivated social cognition (Jost et al., 2003) regarding how belief systems relate to existential anxiety. Conservatism as motivated social cognition posits that politically conservative ideologies are uniquely capable of minimizing fears about death. In contrast, TMT asserts that ideological rigidity is associated with less fear of death but it also promotes aggression and intolerance against those with different beliefs. The relation of ideological rigidity and political conservatism to death anxiety and intolerance of those who have differing worldviews was explored in a sample of American university students (n = 134) and of American respondents from the Prolific crowdsourcing platform (n = 199). The results from both samples supported the hypothesis that ideological rigidity was associated with more negative reactions to people with different beliefs. The results regarding death anxiety were more complicated. In the student sample, personal need for structure was the best predictor of death anxiety, with higher scores on personal need for structure being associated with more death anxiety. In the crowdsourcing sample, social conservatism was the best predictor of death anxiety, with more conservatism being associated with less death anxiety.

Right-wing authoritarianism, social dominance, system justification, and conservative political ideology as predictors of mental health stigma: The Hungarian case.

BACKGROUND: Insights from mental health stigma research indicate the importance of societal and political views on mental health perceptions. Most studies originate from typical Western neo-liberal settings and focus on generic mental health issues. Our research explores these associations in Hungary, an understudied post-communist context with significant stigma levels, examining a broad range of stigmas related to both general and three specific mental illnesses: schizophrenia, depression, and alcohol use disorder (AUD). AIMS: The study aims to connect a wide array of political dispositions to stigma associated with both general and specific mental illnesses, exploring both attitudes and behavioral intentions. METHODS: We surveyed 492 participants (147 males, 342 females) on their political dispositions, including Right-Wing Authoritarianism (RWA), Social Dominance Orientation (SDO), general and economic system justification, and conservative political ideology, and their attitudes toward general and specific mental illnesses. Regression analyses identified key political dispositions influencing stigma. RESULTS: RWA was significantly linked to most stigma outcomes, while conservative political ideology showed a selective impact. Other predictors had minimal influence on stigma outcomes. CONCLUSION: Our findings suggest that perceptions of danger, threat, and unconventionality, as indicated by RWA, are crucial for mental health stigmatization in Hungary. Intervention programs should target these factors, particularly in similar contexts.

RESUMO O objetivo deste trabalho foi analisar a literatura sobre o crescimento demográfico e a atuação política dos evangélicos, especialmente no âmbito do Congresso Nacional, em particular, com relação à política de saúde das mulheres e dos Direitos Sexuais e Reprodutivos (DSR). Trata-se de uma revisão narrativa da produção científica nacional registrada no portal de periódicos da Coordenação de Aperfeiçoamento do Pessoal de Nível Superior (Capes), no período 2016-2021, usando os descritores "evangélico", "agenda neoconservadora" e "saúde das mulheres". Foram selecionados 80 artigos que tratam da relação entre o crescimento do número de igrejas evangélicas e de fiéis vinculados a essas organizações religiosas no Brasil. Do conjunto do artigos analisados, 42,5% analisam a agenda defendida pelos setores religiosos do campo conservador, incluindo um conjunto de temas, tais como política, sexualidade e reprodução, 'ideologia de gênero', direitos humanos da população LGBTQIA+, DSR, aborto, educação sexual nas escolas, casamento entre pessoas do mesmo sexo, estatuto da família, estatuto do nascituro, violência sexual, frentes em defesa da vida e da família, religiões de matriz africana, racismo religioso e intolerância religiosa. Assim, enfatiza-se a importância desse tema nas pesquisas em saúde coletiva, principalmente na área de política, planejamento e gestão em saúde.

ABSTRACT The aim of this study was to analyze the literature on the demographic growth and political action of evangelicals, especially in the context of the National Congress, in particular, with regard to women's health policy and Sexual and Reproductive Rights (DSR). This is a narrative review of the national scientific production registered in the journal portal of the Coordination for the Improvement of Higher Education Personnel (CAPES), in the period 2016-2022, using the descriptors "evangelical", "neoconservative agenda" and "women's health". We selected 80 articles that deal with the relationship between the growth of the number of evangelical churches and faithful linked to these churches in Brazil. Of the articles analyzed, 42.5% examine the agenda defended by religious sectors of the conservative field, including a set of themes, such as politics, sexuality and reproduction, 'gender ideology', human rights of the LGBTQIA+ population, DSR, abortion, sex education in schools, same-sex marriage, family status, status of the unborn child, sexual violence, fronts in defense of life and family, religions of African origin, religious racism and religious intolerance. Thus, the importance of this theme in public health research is emphasized, especially in the area of health policy, planning and management.

Pleistocene climate oscillations have shaped the expansion and contraction speciation model of the globose Eriosyce sect. Neoporteria cacti in Central Chile.

BACKGROUND AND AIMS: Pleistocene climatic oscillations, characterized by arid (interglacial) and pluvial (glacial) phases, have profoundly impacted the floras of Mediterranean climates. Our study investigates the hypothesis that these climatic extremes have promoted phases of range expansion and contraction in the Eriosyce sect. Neoporteria, resulting in pronounced genetic structuring and restricted gene flow. METHODS: Utilizing nuclear microsatellite markers, we genotyped 251 individuals across 18 populations, encompassing all 14 species and one subspecies within the Eriosyce sect. Neoporteria. Additionally, Species Distribution Models (SDMs) were employed to reconstruct past (Last Interglacial, Last Glacial Maximum, Mid-Holocene) and current potential distribution patterns, aiming to delineate the climatic influences on species' range dynamics. KEY RESULTS: The gene flow analysis disclosed disparate levels of genetic interchange among species, with marked restrictions observed between entities that are geographically or ecologically separated. Notably, E. subgibbosa from Hualpen emerged as genetically distinct, warranting its exclusion for clearer genetic clustering into north, central, and south clusters. The SDMs corroborated these findings, showing marked range expansions during warmer periods and contractions during colder times, indicating significant shifts in distribution patterns in response to climatic changes. CONCLUSIONS: Our findings emphasize the critical role of Pleistocene climatic fluctuations in driving the dynamic patterns of range expansions and contractions that have led to geographic isolation and speciation within the Eriosyce sect. Neoporteria. Even in the face of ongoing gene flow, these climate-driven processes have played a pivotal role in sculpting the species' genetic architecture and diversity. This study elucidates the complex interplay between climatic variability and evolutionary dynamics among Mediterranean cacti in central Chile, highlighting the necessity of considering historical climatic millenial oscillations in conservation and evolutionary biology studies.

Ecological niche divergence or ecological niche partitioning in a widespread Neotropical bird lineage.

Ecological niche divergence is generally considered to be a facet of evolution that may accompany geographic isolation and diversification in allopatry, contributing to species' evolutionary distinctiveness through time. The null expectation for any two diverging species in geographic isolation is that of niche conservatism, wherein populations do not rapidly shift to or adapt to novel environments. Here, I test ecological niche divergence for a widespread, pan-American lineage, the avian genus of martins (Progne). The genus Progne includes migrant and resident species, as well as geographically restricted taxa and widespread, intercontinentally distributed taxa, thus providing an ideal group in which to study the nature of niche divergence within a broad geographic mosaic. I obtained distributional information for the genus from publicly available databases and created ecological niche models for each species to create pairwise comparisons of environmental space. I combined these data with the most up-to-date phylogeny of Progne currently available to examine the patterns of niche evolution within the genus. I found limited evidence for niche divergence across the breeding distributions of Progne, and much stronger support for niche conservatism with patterns of niche partitioning. The ancestral Progne had a relatively broad ecological niche, like extant basal Progne lineages, and several geographically localized descendant species occupy only portions of this larger ancestral niche. I recovered strong evidence of breeding niche divergence for four of 36 taxon pairs but only one of these divergent pairs involved two widespread species (Southern Martin P. elegans vs. Gray-breasted Martin P. chalybea). Potential niche expansion from the ancestral species was observed in the most wide-ranging present-day species, namely the North American Purple Martin P. subis and P. chalybea. I analyzed populations of P. subis separately, as a microcosm of Progne evolution, and again found only limited evidence of niche divergence. This study adds to the mounting evidence for niche conservatism as a dominant feature of diversifying lineages, and sheds light on the ways in which apparently divergent niches may arise through allopatry while not involving any true niche shifts through evolutionary time. Even taxa that appear unique in terms of habitat or behavior may not be diversifying with respect to their ecological niches, but merely partitioning ancestral niches among descendant taxa.

Forecasting species' responses to climate change using space-for-time substitution.

To anticipate species' responses to climate change, ecologists have largely relied on the space-for-time-substitution (SFTS) approach. However, the hypothesis and its underlying assumptions have been poorly tested. Here, we detail how the efficacy of using the SFTS approach to predict future locations will depend on species' traits, the ecological context, and whether the species is declining or introduced. We argue that the SFTS approach will be least predictive in the contexts where we most need it to be: forecasting the expansion of the range of introduced species and the recovery of threatened species. We highlight how evaluating the underlying assumptions, along with improved methods, will rapidly advance our understanding of the applicability of the SFTS approach, particularly in the context of modelling the distribution of species.

Spatial patterns and climatic drivers of phylogenetic structure of regional liverwort assemblages in China.

BACKGROUND AND AIMS: Latitudinal diversity gradients have been intimately linked to the tropical niche conservatism hypothesis, which posits that there has been a strong filter due to the challenges faced by ancestral tropical lineages to adapt to low temperatures and colonize extra-tropical regions. In liverworts, species richness is higher towards the tropics, but the centres of diversity of the basal lineages are distributed across extra-tropical regions, pointing to the colonization of tropical regions by phylogenetically clustered assemblages of species of temperate origin. Here, we test this hypothesis through analyses of the relationship between macroclimatic variation and phylogenetic diversity in Chinese liverworts. METHODS: Phylogenetic diversity metrics and their standardized effect sizes for liverworts in each of the 28 regional floras at the province level in China were related to latitude and six climate variables using regression analysis. We conducted variation partitioning analyses to determine the relative importance of each group of climatic variables. KEY RESULTS: We find that the number of species decreases with latitude, whereas phylogenetic diversity shows the reverse pattern, and that phylogenetic diversity is more strongly correlated with temperature-related variables compared with precipitation-related variables. CONCLUSIONS: We interpret the opposite patterns observed in phylogenetic diversity and species richness in terms of a more recent origin of tropical diversity coupled with higher extinctions in temperate regions.

Radiating diversification and niche conservatism jointly shape the inverse latitudinal diversity gradient of Potentilla L. (Rosaceae).

BACKGROUND: The latitudinal diversity gradient (LDG), characterized by an increase in species richness from the poles to the equator, is one of the most pervasive biological patterns. However, inverse LDGs, in which species richness peaks in extratropical regions, are also found in some lineages and their causes remain unclear. Here, we test the roles of evolutionary time, diversification rates, and niche conservatism in explaining the inverse LDG of Potentilla (ca. 500 species). We compiled the global distributions of ~ 90% of Potentilla species, and reconstructed a robust phylogenetic framework based on whole-plastome sequences. Next, we analyzed the divergence time, ancestral area, diversification rate, and ancestral niche to investigate the macroevolutionary history of Potentilla. RESULTS: The genus originated in the Qinghai-Tibet Plateau during the late Eocene and gradually spread to other regions of the Northern Hemisphere posterior to the late Miocene. Rapid cooling after the late Pliocene promoted the radiating diversification of Potentilla. The polyploidization, as well as some cold-adaptive morphological innovations, enhanced the adaptation of Potentilla species to the cold environment. Ancestral niche reconstruction suggests that Potentilla likely originated in a relatively cool environment. The species richness peaks at approximately 45 °N, a region characterized by high diversification rates, and the environmental conditions are similar to the ancestral climate niche. Evolutionary time was not significantly correlated with species richness in the latitudinal gradient. CONCLUSIONS: Our results suggest that the elevated diversification rates in middle latitude regions and the conservatism in thermal niches jointly determined the inverse LDG in Potentilla. This study highlights the importance of integrating evolutionary and ecological approaches to explain the diversity pattern of biological groups on a global scale.

Habitat differentiation and environmental adaptability contribute to leaf size variations globally in C3 and C4 grasses.

The grass family (Poaceae) dominates ~43 % of Earth's land area and contributes 33 % of terrestrial primary productivity that is critical to naturally regulating atmosphere CO2 concentration and global climate change. Currently grasses comprise ~11,780 species and ~50 % of them (~6000 species) utilize C4 photosynthetic pathway. Generally, grass species have smaller leaves under colder and drier environments, but it is unclear whether the primary drivers of leaf size differ between C3 and C4 grasses on a global scale. Here, we analyzed 34 environmental variables, such as latitude, elevation, mean annual temperature, mean annual precipitation, and solar radiation etc., through a comparatively comprehensive database of ~3.0 million occurrence records from 1380 C3 and 978 C4 grass species (2358 species in total). Results from this study confirm that C4 grasses have occupied habitats with lower latitudes and elevations, characterized by warmer, sunnier, drier and less fertile environmental conditions. Grass leaf size correlates positively with mean annual temperature and precipitation as expected. Our results also demonstrate that the mean temperature of the wettest quarter of the year is the primary control for C3 leaf size, whereas C4 leaf size is negatively correlated with the difference between summer and winter temperatures. For C4 grasses, phylogeny exerts a significant effect on leaf size but is less important than environmental factors. Our findings highlight the importance of evolutionarily contrasting variations in leaf size between C3 and C4 grasses for shaping their geographical distribution and habitat suitability at the global scale.

Climatic niche evolution and niche conservatism of Nymphaea species in Africa, South America, and Australia.

BACKGROUND: Interest in the evolution of climatic niches, particularly in understanding the potential adaptive responses of species under climate change, has increased both theoretically and within macroecological studies. These studies have provided valuable insights into how climatic traits of species influence their niche evolution. In this study, we aim to investigate whether niche conservatism plays a role in the species diversification of Nymphaea, a group of aquatic plants with a cosmopolitan distribution that is facing severe habitat loss. We will use climatic models and phylogenetic data for 23 species to reconstruct Nymphaea's niche evolution, measure niche overlap, and assess disparity through time while testing for evolutionary models. RESULTS: There was a lot of overlap in niches both within and between groups, especially for species that can be found in many places. The breadth and peaks of the niche profile varied depending on the bioclimatic variables, which suggested that the species evolved differently to cope with changes in climate. The analysis also showed that evolutionary changes happened across the phylogeny, with weak to moderate signals. The morphological disparity index (MDI) values indicated that there were disparities within subclades over time but not between or among them. Niche reconstruction and evolution analysis revealed both convergent and divergent evolution among various variables. For example, N. immutabilis, N. atrans, N. violancea, and N. nouchali evolved towards intermediate temperatures for bio2 and bio3 (isothermity) while moving towards extreme temperatures for bio8 and bio9 (wettest and driest average quarterly temperatures). CONCLUSION: Our study will improve our understanding of how changes in climatic niches are potentially driving the evolution of Nymphaea. It has significant scientific implications for the limits, assemblages, evolution, and diversification of species. This information is crucial for the ongoing efforts of conservation and management, particularly considering the inevitable effects of climate change.

Taking Stock and Looking Forward to the Future of Pathogen Politics in Light of New Insights and Recommendations: COVID-19 Threat Was Meaningfully Associated With Support for Liberal Policies in the United States.

Infectious disease outbreaks are expected to predict support for conservative policies. However, earlier studies (January-June, 2020) reached conflicting findings regarding the association between COVID-19 threat and policy preferences in the United States. We revisit this issue by analyzing five nationally representative surveys conducted during the relatively severe periods of the pandemic (August 2020-December, 2020; total N = 82,753). Using Bayesian inference, we find strong evidence that subjective (e.g., fear of infection and pandemic outrage) but not objective (e.g., local cases and deaths) threat predicted support for liberal policies (e.g., immigration and universal health care). Meta-analyses revealed that the estimates depend on the type of subjective (.05 ≥ r ≤ .60) or objective (.00 ≥ r ≤ .14) COVID-19 threat. We propose an emotion-mediated dual-process model of pathogen management suggesting that infectious disease outbreaks activate both avoidance and caregiving motives that translate, respectively, into support for right-wing and left-wing policies.

Karyotypic stasis and its implications for extensive hybridization events in corallivores species of butterflyfishes (Chaetodontidae).

The butterflyfishes (Chaetodontidae), emblematic inhabitants of coral reef environments, encompass the majority of known coralivorous species and show one of the highest hybridization rates known among vertebrates, making them an important evolutionary model. The vast knowledge about their life history and phylogenetic relationships contrasts with scarce information on their karyotype evolution. Aiming to expand the cytogenetic data of butterflyfishes and evaluate their karyotype evolution in association with evolutionary aspects, we conducted an extensive cytogenetic analysis in 20 species (Heniochus pleurotaenia and 19 Chaetodon spp.) from the Atlantic and Indo-Pacific regions, comparing the karyotype macrostructure and the arrangement of the 18S and 5S rDNA repetitive DNA classes in their chromosomes. The results demonstrate that butterflyfishes underwent a period of karyotypic stasis, as evidenced by their homoploid and structurally identical basal karyotype, which has 2n = 48 acrocentric chromosomes and is shared by 90% of species. Only C. trifascialis (2n = 48; FN = 50) and C. andamanensis (2n = 48; FN = 52) stood out because they both had karyotypes that diverged due to pericentric inversions. The microstructural arrays of 18S rDNA and 5S rDNA sequences were primarily comprised by single and independent loci on homologous chromosomes, indicating that there was little reshuffling among sets of orthologue chromosomes of species. Geographical comparisons revealed similar karyotypes between individuals of C. striatus from the Greater Caribbean and those of the coast of Brazil, corroborating previous data of gene flow through Amazon/Orinoco plume. The conservative chromosomal patterns in the butterflyfishes, likely overcome the limitations related to segregation and pairing of heterospecific complements and reinforce their contribution to the high degree of hybrid viability and introgression in Chaetodon species.

Palliative and hegemonic dimensions of conservatism: the mitigating role of institutional trust in shaping attitudes toward migrants and migration policy preferences.

The study explores the links between palliative and hegemonic dimensions of conservatism, attitudes toward migrants and restrictive migration policy preferences. Participants reported on their palliative dimension (social conservatism, traditionalism) and hegemonic dimension (social dominance orientation, collective narcissism) of conservatism, trust in government, attitudes toward migrants, and restrictive migration policy preferences. The results show that both dimensions of conservatism are indirectly linked to more restrictive migration policy preferences through negative attitudes toward migrants. Moreover, the present study indicates that increasing institutional trust may be an effective mechanism mitigating negative attitudes toward migrants for individuals high in the palliative dimension of conservatism.

Eco-evolutionary evidence for the global diversity pattern of Cycas (Cycadaceae).

The evolution of the latitudinal diversity gradient (LDG), characterized by a peak in diversity toward the tropics, has captured significant attention in evolutionary biology and ecology. However, the inverse LDG (i-LDG) mechanism, wherein species richness increases toward the poles, remains inadequately explored. Cycads are among one of the oldest lineages of extant seed plants and have undergone extensive diversification in the tropics. Intriguingly, the extant cycad abundance exhibits an i-LDG pattern, and the underlying causes for this phenomenon remain largely elusive. Here, using 1,843 nuclear genes from a nearly complete sampling, we conducted comprehensive phylogenomic analyses to establish a robust species-level phylogeny for Cycas, the largest genus within cycads. We then reconstructed the spatial-temporal dynamics and integrated global environmental data to evaluate the roles of species ages, diversification rates, contemporary environment, and conservatism to ancestral niches in shaping the i-LDG pattern. We found Cycas experienced decreased diversification rates, coupled with the cooling temperature since its origin in the Eocene from continental Asia. Different regions have distinctively contributed to the formation of i-LDG for Cycas, with the northern hemisphere acting as evolutionary museums and the southern hemisphere serving as cradles. Moreover, water-related climate variables, specifically precipitation seasonality and potential evapotranspiration, were identified as paramount factors constraining Cycas species richness in the rainforest biome near the equator. Notably, the adherence to ancestral monsoonal climates emerges as a critical factor in sustaining the diversity pattern. This study underscores the imperative of integrating both evolutionary and ecological approaches to comprehensively unravel the mechanisms underpinning global biodiversity patterns.

Nitrogen supply neutralizes the nanoplastic-plant interaction in a coastal wetland.

The presence of nanoplastics posed a potential threat to coastal saline-alkaline wetlands where nitrogen (N) fertilizer is being implemented as an important ecological restoration measure. Notwithstanding, the effects of N inputs on plant community in polypropylene-nanoplastics (PP-NPs) coexistence environments are largely unknown. To address this, we investigated the effects of PP-NPs addition alone or combined N supply on community aboveground biomass, morphological traits, diversity, composition, niche differentiation, interspecific interactions, and assembly. Our results showed that the PP-NPs addition alone reduced community aboveground biomass and morphological traits. However, the addition of high concentration (0.5%) PP-NPs alone favored community α-diversity and reduced community stability, which could be weakened through combined N supply. Overall, the effect of PP-NPs addition alone on plant community composition was greater than that of combined N supply. We also demonstrated PP-NPs addition alone and combined N supply reduced the niche breadth of the plant community and affected the niche overlap of dominant species. In the assembly of plant communities, stochastic processes played a dominant role. We conclude that N fertilization can amend the terrestrial nanoplastics pollution, thus mitigating the effects of PP-NPs on the plant community.
