The Society for the Study of Species Biology has announced the recipient of the 17th Plant Species Biology Best Paper Award. The winning paper, titled "Environmental and genetic effects on phenotypic differences between Elaeocarpus photiniifolia ecotypes in dry and mesic habitats on a Japanese oceanic island," explores how different environmental conditions have led to reproductive isolation and genetic differentiation in a specific plant species. Another paper, titled "The epiphytic orchid Vanda falcata is predominantly associated with a single Tulasnellaceae fungus in adulthood, and Ceratobasidiaceae fungi strongly induce its seed germination in vitro," investigates the symbiotic relationships between orchids and mycorrhizal fungi at different stages of growth. Both papers are featured in recent issues of Plant Species Biology. [Extracted from the article]

- Abstract
Across populations, human morbidity and mortality risks generally follow clear gradients, with socially-disadvantaged individuals and groups tending to have higher morbidity and mortality at all life stages relative to those more socially advantaged. Anthropologists specialize in understanding the proximate and ultimate factors that shape variation in human biological functioning and health and are therefore well-situated to explore the relationships between social position and health in diverse ecological and cultural contexts. While human biologists have developed sophisticated methods for assessing health using minimally-invasive methods, at a disciplinary level, we have room for conceptual and methodological improvement in how we frame, measure, and analyze the social inequities that might shape health inequities. This toolkit paper elaborates on some steps human biologists should take to enhance the quality of our research on health inequities. Specifically, we address: (1) how to frame unequal health outcomes (i.e., inequalities vs. disparities vs. inequities) and the importance of identifying our conceptual models of how these inequities emerge; (2) how to measure various axes of social inequities across diverse cultural contexts, and (3) approaches to community collaboration and dissemination. We end by discussing (4) future directions in human biology research of health inequities, including understanding the ultimate causes of sensitivity to social inequities and transitioning from research to action., (© 2022 Wiley Periodicals LLC.)

A practical method for collecting, storing, and transporting liquid biological samples in a dry state for subsequent hormone metabolite analyses is presented. This method employs the use of ordinary filter paper strips that imbibe liquid samples. Samples taken up by the filter paper were allowed to dry and were retained at ambient conditions in capped vials for up to 5 years prior to analysis. Examples presented in the present report include urine samples from human and nonhuman primates as well as solubilized fecal samples from nonhuman primates. Hormone metabolite analysis of the paper-stored samples provided data that were comparable to the results obtained from analyses of the original liquid samples. One year of storage had no effect on hormone concentration. Five years of storage resulted in concentrations that were quantitatively less bat qualitatively similar to the concentrations obtained by direct analysis of the initial samples. These data demonstrate the versatility and reliability of paper as a matrix for biological samples that may provide a more convenient approach for collecting and transporting samples collected in the field.

Climate change, land clearing and invasive species are affecting ecosystems in concert, so effective management requires knowledge sharing and collaboration across multiple fields of applied ecological research.We provide an examination of the growth and interconnectivity of four major subfields of applied ecology: climate change biology, conservation biology, invasion biology and restoration ecology; estimated using citations from the entire population of peer‐reviewed journal articles published between 1990 and 2017.Over this period applied ecological research has grown from 2% of new ecology papers to over 20%. The subfields each represented c. 6% of new ecology publications in 2017, with the exception of restoration ecology at c. 3%. Inter‐subfield citation probabilities also increased consistently over our study period.Despite these positive trends, we identified apparent barriers to future integration of these research areas. While the probability that citations in one subfield would include at least one paper from another subfield was high, the magnitude of cross‐subfield citations was low. Subfields also exhibited segregated publishing habits, asynchronous research foci and a strong preference for citing application over theory.Synthesis and applications. Despite strong overall growth in applied ecological research, segregation of subfields in papers and journals may limit opportunities to identify co‐benefits and complementary theoretical frameworks. This has the potential to result in suboptimal ecological management outcomes.

In cold agglutinin disease, monoclonal red blood cell autoantibodies, termed cold agglutinins, induce haemolysis in patients exposed to the cold. Commonly, these autoantibodies are directed against the developmentally regulated I/i blood groups. A second blood group system, the Pr system (located on glycophorins), is involved less frequently. Anti-Pr cold agglutinins recognize either alpha 2,3- or alpha 2,6-linked N-acetylneuraminic acid as the immunodominant group. Cold agglutinins of anti-I/i specificity show a remarkable restriction in their genomic repertoire of the immunoglobulin heavy and light-chain immunoglobulin-variable domain (i.e. exclusive use of VH4-34 in heavy chains). For anti-Pr cold agglutinins, preliminary data on the repertoire of the light-chain variable domain indicate a preference for the subgroup Vkappa IV. To elucidate restrictions in the light-chain variable-domain subgroup repertoire of anti-Pr cold agglutinins systematically, and to discuss these results in the context of their anti-Pr1–3 subclassification and immunodominant sialic acid, light chains in 13 anti-Pr cold agglutinins were investigated. The anti-Pr light chains were isolated using temperature-dependent absorption/elution techniques. Subsequently, they were subjected to N-terminal Edman degradation, and the light chain Vkappa subgroup was affiliated using the Kabat database. Five of 13 (38%) light chains belonged to Vkappa IV, five of 13 (38%) to Vkappa I and three of 13 (23%) to Vkappa III. Anti-Pr with Vkappa IV subgroup light chains exclusively recognized alpha 2,3-linked N-acetylneuraminic acid. Including data from the literature, the repertoire of the light-chain variable domain in pathological anti-Pr cold agglutinins exhibits a clear bias towards the use of the single germline gene-derived subgroup, Vkappa IV (eight of 17 or 47%). The association of Vkappa IV subgroup light chain-containing anti-Pr cold agglutinins with binding to alpha 2,3-, but not alpha 2,6-linked N-acetyneuraminic acid raises speculations about a possible role of subgroup-derived determinants in anti-Pr binding.

Local-regional (LR) species diversity plots were conceived to assess the contribution of regional and local processes in shaping the patterns of biological diversity, but have been used also to explore the scaling of diversity in terms of its alpha, beta, and gamma components. Here we explore the idea that patterns in the geographical ranges of species over a continent can determine the shape of small region to large region (SRLR) plots, which are equivalent to LR plots when comparing the diversity of sites at two regional scales. To test that idea, we analysed the diversity patterns at two regional scales for the mammals of North America, defined as the mainland from Alaska and Canada to Panama. We developed a theoretical model relating average range size of species over a large-scale region with its average regional point species diversity (RPD). Then, we generated a null model of expected SRLR plots based on theoretical predictions. Species diversities at two scales were modelled using linear and saturation functions for Type I and Type II SRLR relationships, respectively. We applied the models to the case of North American mammals by examining the regional diversity and the RPD for 21 large-scale quadrats (with area equal to 160,000 km2), arranged along a latitudinal gradient. Our model showed that continental and large-scale regional patterns of distribution of species can generate both types of SRLR relationship, and that these patterns can be reflected in LR plots without invoking any kind of local processes. We found that North American nonvolant mammals follow a Type I SRLR relationship, whereas bats follow a Type II pattern. This difference was linked to patterns in which species of the two mammalian groups distribute in geographical space. Traditional LR plots and the new SRLR plots are useful tools in exploring the scaling of species diversity and in showing the relationship between distribution and diversity. Their usefulness in comparing the relative role of local and regional processes is, however, very limited. [ABSTRACT FROM AUTHOR]

To quantify the latitudinal gradient in species richness in the New World Triatominae and to explore the species-energy and area hypotheses as possible causes. The gradient was studied for North and South America, between 43° N and 32° S. A database was constructed containing the geographical distribution of the 118 New World Triatominae species based on data extracted from several published sources. Species richness was recorded as the number of species present within 5° latitudinal bands. We used univariate and multivariate models to analyse the relationship between area within each latitudinal belt, land surface temperature, and potential evapotranspiration as explanatory variables, and species richness. All variables were georeferenced and data were extracted using a GIS. Species richness of Triatominae increases significantly from the poles towards the Equator, peaking over the 5°−10 ° S latitudinal band. It increases according to a linear model, both north and south of the Equator, although a quadratic model fits better to southern hemisphere data. Richness correlates with habitable geographical area, when it is analysed through a nonlinear multiple regression factoring out latitude, only in the southern hemisphere. Regarding the species-energy hypothesis, a multiple regression analysis controlling the effect of latitude shows a significant relationship between temperature and species richness. This effect is more pronounced in the southern hemisphere. Species richness shows a strong longitudinal trend south of the Equator (increasing to the east), but not north of the Equator. This differential pattern is reflected in significant interactions between longitude and both latitude and temperature in models of the species richness of the New World Triatominae. To our knowledge, this is the first time that a latitudinal gradient in species richness has been shown and analysed for obligate haematophagous organisms, and it shows that the species–energy hypothesis can account for this phenomenon. This relationship is stronger in the southern hemisphere. [ABSTRACT FROM AUTHOR]

Litter decay dynamics of paper birch (Betula papyrifera) were assessed at the Aspen free-air CO2 enrichment (FACE) facility in northern Wisconsin, USA. Leaf litter was decomposed for 12 months under factorial combinations of 360 vs. 560 μL CO2 L−1, crossed with 36 vs. 55 nL O3 L−1. To differentiate between substrate quality and environment effects, litterbags were placed in their Native Plots of origin or transplanted into the other treatments. CO2 enrichment, regardless of O3 concentration, produced poorer quality litter (high C/N, lignin/N and condensed tannins) than did ambient CO2 (low C/N, lignin/N and condensed tannins). Substrate quality differences were reflected in the mass loss rates (k-values), which were high for litter generated under ambient CO2 (0.887 year−1) and low for litter generated under elevated CO2 (0.674 year−1). The rate-retarding effects of CO2 enrichment were neither alleviated nor exacerbated by O3 exposure. Decay rates varied, however, depending on whether litter was placed back into its plot of origin or transplanted to Common Gardens. The results of this study are species specific, but they have important implications for understanding the processes regulating storage of fixed C and the release of CO2 from northern forest ecosystems.

Developmental Psychobiology publishes papers from the disciplines of psychology, biology, neuroscience, and medicine that contribute to an understanding of behavioral development. Research focuses on development in the embryo/fetus, neonate, juvenile, and adult as well as multidisciplinary research that relates behavioral development to anatomy, physiology, biochemistry, genetics, and evolution. The journal represents a broad phylogenetic perspective on behavioral development by including studies on invertebrates, fish, birds, non-human primates, and humans. This paper presents an analysis of empirical articles published since its first issue in 1968. This analysis covers number of authors, sex of first author, evidence of grant support, and participation of investigators from outside the US. Additionally, the analysis includes the topic of research, level of analysis, and subject of experimental study. Over its 32-year history, Developmental Psychobiology has published papers on a wide range of topics representing a broad phylogenetic perspective with a continued focus on behavioral investigation. This analysis revealed trends such as an increase in the number of studies at a physiology/anatomy level, an increase in studies with human subjects, and increases in contributions from investigators outside of the United States as well as women. © 2000 John Wiley & Sons, Inc.

Developed countries have an even distribution of published papers on the seventeen model organisms. Developing countries have biased preferences for a few model organisms which are associated with endemic human diseases. A variant of the Hirsch-index, that we call the mean
mo h-index (“model organism h-index”), shows an exponential relationship with the amount of papers published in each country on the selected model organisms. Developing countries cluster together with low meanmo h-indexes, even those with high number of publications. The growth curves of publications on the recent model Caenorhabditis elegans in developed countries shows different formats. We also analyzed the growth curves of indexed publications originating from developing countries. Brazil and South Korea were selected for this comparison. The most prevalent model organisms in those countries show different growth curves when compared to a global analysis, reflecting the size and composition of their research communities.

BIOLOGICAL extinction ,ENDANGERED species ,LISTING of securities ,SPECIES ,BIOLOGY - Abstract
Currently 1677 species are listed under the U.S. Endangered Species Act (ESA), yet only a small percentage have been delisted due to recovery. In the fall of 2021, the U.S. Fish and Wildlife Service proposed delisting 23 species due to extinction. Tracking changes in species 'recovery status over time is critical to understanding species' statuses, informing adaptive management strategies, and assessing the performance of the ESA to prevent further species loss. In this paper, we describe four key obstacles in tracking species recovery status under the ESA. First, ESA 5‐year reviews lack a standardized format and clear documentation. Second, despite having been listed for decades, many species still suffer major data gaps in their biology and threats, rendering it difficult if not impossible to track progress towards recovery. Third, many species have continued declining after listing, yet given the above (1 & 2), understanding potential causes (proximate and/or ultimate) can be difficult. Fourth, many species currently have no path to clear recovery, which represents a potential failing of the process. We conclude with a discussion of potential policy responses that could be addressed to enhance the efficacy of the ESA. [ABSTRACT FROM AUTHOR]

ECOLOGY ,GENDER ,AUTHORSHIP collaboration ,BIOLOGY - Abstract
Senior positions in academia such as tenured faculty and editorial positions often exhibit large gender imbalances across a broad range of research disciplines. The forces driving these imbalances have been the subject of extensive speculation and a more modest body of research. Given the central role publications play in determining individual outcomes and progress in academic settings, unequal patterns of authorship across gender could be a potent driver of observed gender imbalance in academia. Here, we investigate patterns of co‐authorship across four journals in ecology and evolutionary biology at four time‐points spanning four decades. Co‐authorship patterns are of interest because collaborations are important in scientific research, affecting individual researcher productivity, and increasingly, funding opportunities. Based on inferred gender from set criteria, we found significant differences between male and female researchers in their tendency to publish with female co‐authors. Specifically, compared to women, male researchers in the last author position were more likely to co‐author papers with other males. While we did find that the proportion of female co‐authors has increased modestly over the last thirty years, this is strongly correlated with an increase in the average number of authors per paper over time. Additionally, the proportion of female co‐authors on papers remains well below the proportion of PhDs awarded to females in biology. [ABSTRACT FROM AUTHOR]

The problem of invasive species spread requires timely analysis of the biological dynamics that lead to spatial dispersion. Here, a spatial dynamic model captures the invasive behavior of the recently introduced emerald ash borer (EAB) (Agrilus planipennis) and its impacts on host ash (Fraxinus spp.) trees. Parasite–host system dynamics are extended spatially using the Spatial Modeling Environment. The resulting model can serve as a repository for changing knowledge about EAB biology and behavior. Studies of the rapid EAB infestation in Michigan are used to inform simulations of its spread in DuPage County, Illinois, USA. We use a geographic information system to create heterogeneous host landscapes and to test alternative policy scenarios. We test the effectiveness of three suppression scenarios: the Michigan eradication strategy, firewood quarantines, and ash tree thinning. Simulations demonstrate that EAB spatial spread accelerates with degraded host capacity, with results pointing to firewood quarantines as the most effective solution.

Since the early 1990s, ecologists and evolutionary biologists have aggregated primary research using meta‐analytic methods to understand ecological and evolutionary phenomena. Meta‐analyses can resolve long‐standing disputes, dispel spurious claims, and generate new research questions. At their worst, however, meta‐analysis publications are wolves in sheep's clothing: subjective with biased conclusions, hidden under coats of objective authority. Conclusions can be rendered unreliable by inappropriate statistical methods, problems with the methods used to select primary research, or problems within the primary research itself. Because of these risks, meta‐analyses are increasingly conducted as part of systematic reviews, which use structured, transparent, and reproducible methods to collate and summarise evidence. For readers to determine whether the conclusions from a systematic review or meta‐analysis should be trusted – and to be able to build upon the review – authors need to report what they did, why they did it, and what they found. Complete, transparent, and reproducible reporting is measured by 'reporting quality'. To assess perceptions and standards of reporting quality of systematic reviews and meta‐analyses published in ecology and evolutionary biology, we surveyed 208 researchers with relevant experience (as authors, reviewers, or editors), and conducted detailed evaluations of 102 systematic review and meta‐analysis papers published between 2010 and 2019. Reporting quality was far below optimal and approximately normally distributed. Measured reporting quality was lower than what the community perceived, particularly for the systematic review methods required to measure trustworthiness. The minority of assessed papers that referenced a guideline (~16%) showed substantially higher reporting quality than average, and surveyed researchers showed interest in using a reporting guideline to improve reporting quality. The leading guideline for improving reporting quality of systematic reviews is the Preferred Reporting Items for Systematic reviews and Meta‐Analyses (PRISMA) statement. Here we unveil an extension of PRISMA to serve the meta‐analysis community in ecology and evolutionary biology: PRISMA‐EcoEvo (version 1.0). PRISMA‐EcoEvo is a checklist of 27 main items that, when applicable, should be reported in systematic review and meta‐analysis publications summarising primary research in ecology and evolutionary biology. In this explanation and elaboration document, we provide guidance for authors, reviewers, and editors, with explanations for each item on the checklist, including supplementary examples from published papers. Authors can consult this PRISMA‐EcoEvo guideline both in the planning and writing stages of a systematic review and meta‐analysis, to increase reporting quality of submitted manuscripts. Reviewers and editors can use the checklist to assess reporting quality in the manuscripts they review. Overall, PRISMA‐EcoEvo is a resource for the ecology and evolutionary biology community to facilitate transparent and comprehensively reported systematic reviews and meta‐analyses.

The aim of this paper is to discover analytically the interactional responses of populations in a dynamic region where the reaction–diffusion process with forcing effects takes place through traveling wave solutions. An expansion method is considered here to properly capture the responses for the first time. In order to profoundly analyze the physical and mathematical discussions, some illustrative behavioral results are exhibited for various values of physical parameters. Especially for the different values of diffusion coefficients in the model under consideration, their effects on the behavior of the solitary wave are discussed and observationally supported by considering various illustrations. It is also seen that the solutions representing the diffusion seen to be in the form of the behavior of hexagonal Turing patterns in different time periods. The application of this study in mathematical biology is to analyze the relationship between the population density of certain species in any local region and the specific population density with invasion characteristics. In addition, the formation of the extinction vortex of the invading population, depending on the characteristics of the solutions presented, is also descriptively discussed. [ABSTRACT FROM AUTHOR]

There are many different kinds of models, and they play many different roles in the scientific endeavour. Neuroscience, and biology more generally, has understandably tended to emphasise empirical models that are grounded in data and make specific, experimentally testable predictions. Meanwhile, strongly idealised or ‘toy’ models have played a central role in the theoretical development of other sciences such as physics. In this paper, we examine the nature of toy models and their prospects in neuroscience. [ABSTRACT FROM AUTHOR]

At the time of the recent description of Beytell's bullfrog (Pyxicephalus beytelli), no information about the breeding biology of this frog was known to science. The intensive publicity in the social media that followed this description caught the eye of a USA‐based film maker who incidentally recently filmed the breeding biology of this frog in the Okavango Delta in northern Botswana. This paper is based on these observations. [ABSTRACT FROM AUTHOR]

There is a tension at the heart of Aristotle's understanding of organic activities, created by his appeals to the productive activities of craftsmen and his use of normative language to characterize the goals of such activities. In this paper I discuss two ways of interpreting Aristotle's teleology aimed at resolving this tension, and discuss a closely analogous tension at the heart of a number of contemporary defenses of teleological reasoning in biology.

Telomere biology disorder (TBD) can present within a wide spectrum of symptoms ranging from severe congenital malformations to isolated organ dysfunction in adulthood. Diagnosing TBD can be challenging given the substantial variation in symptoms and age of onset across generations. In this report, we present two families, one with a pathogenic variant in ZCCHC8 and another with a novel variant in TERC. In the literature, only one family has previously been reported with a ZCCHC8 variant and TBD symptoms. This family had multiple occurrences of pulmonary fibrosis and one case of bone marrow failure. In this paper, we present a second family with the same ZCCHC8 variant (p.Pro186Leu) and symptoms of TBD including pulmonary fibrosis, hematological disease, and elevated liver enzymes. The suspicion of TBD was confirmed with the measurement of short telomeres in the proband. In another family, we report a novel likely pathogenic variant in TERC. Our comprehensive description encompasses hematological manifestations, as well as pulmonary and hepatic fibrosis. Notably, there are no other reports which associate this variant to disease. The families expand our understanding of the clinical implications and genetic causes of TBD. [ABSTRACT FROM AUTHOR]

Background: With the rapid proliferation of online education, it is incumbent upon teachers to find ways to provide online students with science laboratory experiences. Existing research on online labs focuses heavily on computer‐supported inquiry learning environments, such as virtual laboratories and remote laboratories. There are limited studies on kitchen labs or home labs. Objectives: This study investigated the effectiveness of home labs using lab kits from two perspectives: students' perceptions and experiences of labs conducted in a home environment, as well as whether home labs help with students' knowledge acquisition. Methods: This study employed lab quizzes to assess students' performance and lab reports to evaluate students' ability to interpret the lab results accurately in the authentic home lab contexts. Surveys and semi‐structured interviews were used to collect students' perceptions and experience data regarding these hands‐on experiments at home. Results and Conclusions: We found that students' perceptions of home labs are similar to that of face‐to‐face labs, but they generally perceive home labs to be less complex. Students' performances on lab quizzes and lab reports indicate that the majority of them were able to apply the key scientific concepts to accurately interpret lab results in authentic home lab contexts. Students perceived that home labs provide flexibility and help in connecting learning to the real world. However, they also face challenges such as unexpected results and ambiguity during the process. Implications: Based on the key findings from this study and our reflections, four practice guidelines were provided for teaching hands‐on experiments online. Lay Description: What is already known about this topic: Science‐laboratory activities play a critical role in science education. The lack of best practices for teaching science laboratory activities online has become one of the most significant barriers to online education.Existing online labs research focuses heavily on computer‐supported inquiry learning environments, such as virtual laboratories and remote laboratories. There are limited studies on kitchen labs or home labs and some research has mainly an exploratory nature. What this paper adds: The value of authentic hands‐on learning experience is more than the acquisition of laboratory design skills, but also the acquisition of problem‐solving skills in real‐world.This study reported findings of the evaluation of hands‐on home laboratory activities in an online science course from both students' perception and their knowledge acquisition perspectives.This study also explored the benefits and challenges students faced in home labs. Implication for practice and/or policy: Practical guidance and implications for teaching and learning science online using laboratory activities were provided by sharing our experience and lessons learned through the whole process.We recommend that practitioners incorporate more scaffolding and peer collaboration opportunities as well as key concept reflection as teaching strategies to improve the effectiveness of home lab activities.

- Abstract
Fourier transform infrared (FTIR) spectroscopy is a powerful tool for analyzing the biochemical properties of biological samples such as proteins, cellular materials, and tissues. It provides objective information on samples and has been adopted in many research areas of biomedical and biotechnological interest. FTIR spectroscopy can be performed using different approaches at the macro and micro levels allowing the examination of an incredibly broad class of materials. However, it has become evident that the choice of proper spectra acquisition geometries and the modalities of sample preparation in FTIR spectroscopy analysis require special consideration, especially for certain classes of materials such as cells and tissues. In the present paper, we described the different procedures used for preparing and analyzing different types of biological and biotechnological samples when the more largely available approaches are employed using a commercial FTIR spectrometer. Some basic aspects of data analysis procedures are presented in an Appendix. A certain number of our previous experimental results are reported for demonstrating once more the versatility and the potentiality of FTIR spectroscopy., (© 2022 International Union of Biochemistry and Molecular Biology, Inc.)

49. Dissemination biases in ecology: effect sizes matter more than quality.

Publication and citation decisions in ecology are likely influenced by many factors, potentially including journal impact factors, direction and magnitude of reported effects, and year of publication. Dissemination bias exists when publication or citation of a study depends on any of these factors. We defined several dissemination biases and determined their prevalence across many sub-disciplines in ecology, then determined whether or not data quality also affected these biases. We identified dissemination biases in ecology by conducting a meta-analysis of citation trends for 3867 studies included in 52 meta-analyses. We correlated effect size, year of publication, impact factor and citation rate within each meta-analysis. In addition, we explored how data quality as defined in meta-analyses (sample size or variance) influenced each form of bias. We also explored how the direction of the predicted or observed effect, and the research field, influenced any biases. Year of publication did not influence citation rates. The first papers published in an area reported the strongest effects, and high impact factor journals published the most extreme effects. Effect size was more important than data quality for many publication and citation trends. Dissemination biases appear common in ecology, and although their magnitude was generally small many were associated with theory tenacity, evidenced as tendencies to cite papers that most strongly support our ideas. The consequences of this behavior are amplified by the fact that papers reporting strong effects were often of lower data quality than papers reporting much weaker effects. Furthermore, high impact factor journals published the strongest effects, generally in the absence of any correlation with data quality. Increasing awareness of the prevalence of theory tenacity, confirmation bias, and the inattention to data quality among ecologists is a first step towards reducing the impact of these biases on research in our field.

The envelope method produces efficient estimation in multivariate linear regression, and is widely applied in biology, psychology, and economics. This paper estimates parameters through a model averaging methodology and promotes the predicting abilities of the envelope models. We propose a frequentist model averaging method by minimizing a cross‐validation criterion. When all the candidate models are misspecified, the proposed model averaging estimator is proved to be asymptotically optimal. When correct candidate models exist, the coefficient estimator is proved to be consistent, and the sum of the weights assigned to the correct models, in probability, converges to one. Simulations and an empirical application demonstrate the effectiveness of the proposed method. [ABSTRACT FROM AUTHOR]
