ABSTRACT: The study of genotypic relationships between drought tolerance indices and agronomic traits of interest in wheat breeding is useful for designing selection strategies. The objective of this research was to investigate the cause-and-effect relationships between agronomic traits and drought tolerance indices through the analysis of canonical correlations. Two trials (control and stress) were conducted in winter 2020 in Viçosa, MG, Brazil. The traits evaluated were: (days for heading, plant height, mass and number of grains per spike, mass of one hundred grains, and grain yield). Grain yield data from the control and stress conditions were used to construct five drought tolerance indices. The data were subjected to mixed model analysis for estimation of genetic parameters and prediction of genotypic values (REML/BLUP), and then the genotypic values were used to calculate the correlation coefficients between the traits. Two groups of traits were established for the study of canonical correlations, the first group consisting of agronomic traits and the second by drought tolerance indices. There was a significant genotype effect for all evaluated traits. The canonical pairs were significant, which indicated the existence of dependence between the groups. Days to heading trait can be used in the indirect selection of wheat genotypes for drought tolerance.

RESUMO: O estudo das relações genotípicas entre índices de tolerância à seca e caracteres agronômicos de interesse no melhoramento de trigo é útil para traçar estratégias de seleção. Objetivou-se com este trabalho investigar as relações de causa e efeito entre características agronômicas e índices de tolerância à seca via análise de correlações canônicas. Dois ensaios (controle e estresse) foram conduzidos no inverno de 2020 em Viçosa, MG, Brasil. Foram avaliados os caracteres (dias para o espigamento, altura da planta, massa e número de grãos por espiga, massa de cem grãos e rendimento de grãos). Os dados de produtividade dos ensaios de controle e estresse foram utilizados para construir cinco índices de tolerância à seca. Os dados foram submetidos à análise de modelos mistos para estimação dos parâmetros genéticos e predição dos valores genotípicos (REML/BLUP), em seguida, os valores genotípicos foram utilizados para calcular os coeficientes de correlação entre os caracteres. Dois grupos de caracteres foram estabelecidos para o estudo das correlações canônicas, sendo o primeiro grupo constituído pelas variáveis agronômicas e o segundo pelos índices de tolerância à seca. Houve efeito significativo de genótipo para todas as características avaliadas. Os pares canônicos foram significativos, o que indicou a existência de dependência entre os grupos. O caráter dias para o espigamento pode ser utilizado na seleção indireta de genótipos de trigo para tolerância à seca.

Abstract: The aim of this work is to put forward a methodology to evaluate the oscillatory stability of a power electric system (PES) analyzing the low-frequency oscillatory modes (LFOM) through the processing of synchrophasor measurements Phasor Measurement Units (PMU) of ambient data. The proposed methodology, based on spectral and pseudo-energy analyses and on parametric methods of Canonical Correlation Analysis and Yule-Walker, estimates the LFOM, whose frequency and damping characteristics provide critical information to PES operators to carry out preventive or emergency control actions. The proposed methodology was applied to synthetic measurements for its tuning and to characterize its range and accuracy, and to PMU records of the Ecuadorian power transmission system, successfully identifying the 0.4 Hz inter-area mode of the Ecuador-Colombia interconnection. The contributions of this work are aimed at evaluating the oscillatory stability of the PES through automatic computational tool that processes PMU signals of ambient type data.

Resumen: El objetivo de este trabajo es presentar una metodología para evaluar la estabilidad oscilatoria de un sistema eléctrico de potencia (SEP) mediante el análisis de los modos oscilatorios de baja frecuencia (MOBF) a través del procesamiento de mediciones sincrofasoriales (Phasor Measurement Units PMU) de datos tipo ambiente. La metodología propuesta, basada en los análisis espectral y de pseudoenergía y en los métodos paramétricos de Análisis de Correlación Canónica y de Yule - Walker, estima los MOBF, cuyas características de frecuencia y amortiguamiento brindan información crítica a los operadores del SEP para adoptar acciones de control preventivo o de emergencia. La metodología propuesta fue aplicada a mediciones sintéticas para su sintonización y caracterizar su alcance y precisión, y a registros PMU del sistema de transmisión de energía de Ecuador logrando identificar satisfactoriamente el modo interárea de 0,4 Hz propio de la interconexión Ecuador-Colombia. Las contribuciones de este trabajo están encaminadas a evaluar la estabilidad oscilatoria de los SEP a través de una herramienta computacional automática que procese señales PMU de datos tipo ambiente.

RESUMEN: En antropología forense, se ha demostrado que el hueso radio determina el sexo de los restos humanos en varias poblaciones diferentes. La masa seca y el crecimiento de los huesos largos, incluido el radio, están asociados con los niveles de hormonas sexuales; sin embargo, el uso del peso de los huesos para determinar el sexo no se ha investigado suficientemente. El objetivo de este estudio fue aplicar parámetros morfométricos óseos, incluida la longitud máxima del radio (LMR), la circunferencia en la mitad del radio (CMR) y el peso del radio (PR), a 400 radios de muestra de una población del noreste de Tailandia. Se aplicaron sistémicamente funciones discriminantes univariadas y multivariadas de todos los parámetros. También se determinaron ecuaciones para calcular la clasificación por sexo. El análisis descriptivo de los datos mostró un dimorfismo sexual significativo en todas las variables (p < 0,05). La correlación canónica fue mayor en CMR (0,772) y la relación peso-longitud (0,747). El análisis de función discriminante multivariante mostró que los índices del radio derecho eran ligeramente mayores que los del radio izquierdo. Los parámetros que demostraron los valores más altos de los coeficientes de la función discriminante canónica estandarizada fueron CMR (Rt. = 0,496, Lt. 0,431) y PR (Rt. = 0,681, Lt. = 0,715). Además, los resultados del método multivariable (método paso a paso) indicaron que las mejores tasas de precisión al usar combinaciones de CMR y PR fueron del 94 % (lado derecho) y del 92 % (lado izquierdo). En conclusión, el peso del radio (más que la longitud) es un parámetro eficaz para determinar el sexo.

SUMMARY: In forensic anthropology, the radius bone has been shown to determine the sex of human remains in a number of different populations. The dry mass and growth of long bones, including the radius, are associated with sex hormone levels; however, the use of bone weight to determine sex has not been sufficiently investigated. The aim of this study was to apply bone morphometric parameters, including maximum length of radius (MLR), circumference at the midshaft of radius (CMR), and weight of radius (WR), to 400 sample radii from a Northeastern Thai population. Univariate and multivariate discriminant functions of all parameters were systemically applied. Equations for calculating sex classification were also determined. Descriptive data analysis showed significant sexual dimorphism in all variables (p < 0.05). The canonical correlation was highest in CMR (0.772) and the ratio of weight to length (0.747). Multivariate discriminant function analysis showed that the measured indices of the right radius were slightly greater than those of the left radius. The parameters demonstrating the highest values of the standardized canonical discriminant function coefficients were CMR (Rt. = 0.496, Lt. 0.431) and WR (Rt. = 0.681, Lt. = 0.715). Moreover, the results of the multivariable (stepwise method) indicated that the best accuracy rates for using combinations of CMR and WR were 94 % (right side) and 92 % (left side). In conclusion, the weight of the radius (rather than the length) is an effective parameter in determining sex.

Abstract The different characteristics of the cultural dimensions of a country give rise to different collective behaviors that impact the way of living, the organization of work and the economy. This study investigated the correlations between the cultural dimensions according to Hofstede (power distance, individualism-collectivism, masculinity-femininity, uncertainty avoidance, long-term orientation and indulgence-restraint) and the countries' economic complexity indexes. A canonical correlation analysis was performed to determine the magnitude of the relationships between the two sets of variables. The results revealed significant correlations between culture and complexity, varying according to the countries' income. Cultural characteristics such as lower power distance, greater individualism and greater indulgence were associated with more complex economies, based on innovation and scientific research. Masculinity-femininity and uncertainty avoidance did not show a significant correlation. Greater long-term orientation correlated with more export-diversified economies. These conclusions can guide more effective development policies, respecting cultural particularities. living economy distance individualismcollectivism, individualismcollectivism collectivism, collectivism individualism-collectivism masculinityfemininity, masculinityfemininity masculinity femininity, femininity masculinity-femininity longterm long term indulgencerestraint restraint indulgence-restraint countries indexes variables income economies research Masculinityfemininity Masculinity exportdiversified export diversified policies particularities

Resumo As diversas características das dimensões culturais de um país fazem emergir comportamentos coletivos diferentes que impactam nas formas de se viver, na organização do trabalho e na economia. Este estudo investigou as correlações entre as dimensões culturais segundo Hofstede (distância do poder, individualismo-coletivismo, masculinidade-feminilidade, aversão à incerteza, orientação de longo prazo e indulgência-restrição) e os índices de complexidade econômica dos países. Realizou-se uma análise de correlação canônica para determinar a magnitude das relações entre os dois conjuntos de variáveis. Os resultados revelaram correlações significativas entre cultura e complexidade, variando conforme a renda dos países. Características culturais como menor distância do poder, maior individualismo e maior indulgência associaram-se a economias mais complexas, baseadas em inovação e pesquisa científica. Masculinidade-feminilidade e aversão à incerteza não mostraram correlação significativa. Maior orientação de longo prazo correlacionou-se a economias mais diversificadas nas exportações.

Resumen El uso de TikTok en las campañas políticas se ha convertido en una tendencia local y global, porque abarata la financiación de candidatos y posibilita explorar formatos multimediales. En esta dirección, el objetivo del artículo es analizar el uso de esta red social en las elecciones regionales de Colombia durante el año 2023, teniendo como hipótesis que, independiente del contexto geográfico, TikTok incidió en la elección de los candidatos ganadores y con ello valida la postura teórica de las leyes de la interfaz. La metodología toma como corpus el número de seguidores y "tiktoks" realizados por los dos candidatos con mayor votación en cada uno de los 32 departamentos y capitales de Colombia. El método integra dos estrategias: un análisis descriptivo de redes sociales que evidencia los casos en los que el candidato ganador tenía más seguidores o piezas comunicativas en TikTok, y un análisis de correlación canónica que establece la relación entre la utilización de la red social y las zonas geográficas del país. La discusión sugiere que TikTok se ha convertido en una herramienta fundamental para las campañas políticas que trasciende el territorio y que esta tendencia se mantendrá en ascenso, debido a la singularidad de su algoritmo y diversidad de ofertas para la interacción de usuarios. El artículo aporta a la literatura de campañas electorales, interfaz de TikTok e influencia en contextos territoriales. Por último, se propone una agenda de investigación que profundice en las transformaciones de este fenómeno para la cultura "pop-lítica" y las emociones sociales.

Abstract The use of TikTok in political campaigns has become a global and local trend because it makes it cheaper to finance candidates and allows the exploration of multimedia formats. The article intends to analyze the use of this social media platform in the regional elections of Colombia during 2023, hypothesizing that regardless of the geographical context, it influenced the election of the winning candidates and strengthened the theoretical position of the interface laws. The methodology takes as a corpus the number of followers and TikTok videos made by the two candidates with the highest number of votes in each of Colombia's 32 departments and capitals. The method integrates two strategies: a descriptive analysis of social media that evidences the cases in which the winning candidate had more followers or communicative pieces on TikTok and a canonical correlation analysis that establishes the relationship between the use of the platform and the country's geographical areas. The discussion suggests that TikTok has become a fundamental tool for political campaigns that transcend territory and that this trend will continue to rise due to the uniqueness of its algorithm and the diversity of offers for user interaction. The article contributes to the literature on electoral campaigns, TikTok interface, and influence in territorial contexts. Finally, we propose a research agenda that delves into the transformations of this phenomenon for pop-political culture and social emotions.

ABSTRACT The canonical correlation is used to correlate groups of distinct variables. The objective of this study was to use canonical correlation analysis to evaluate the interaction between water quality attributes clogging-causing and the hydraulic performance of non-pressure compensating drippers operating with dilutions of aquaculture effluent in well water. The experiment was in a completely randomized design in a split-split-plot scheme with three replicates, with five dilutions in the plots (Dilution 1: 100% aquaculture effluent; Dilution 2: 75% aquaculture effluent + 25% well water; Dilution 3: 50% aquaculture effluent + 50% well water; Dilution 4: 25% aquaculture effluent + 75% well water; and Dilution 5: 100% well water), three emitters in the sub-plots (ST (1.6 L h-1), SL (1.6 L h-1) and NJ (1.7 L h-1)), and three operating times in the sub-subplots (0, 80 and 160 hours, in which 0 hours operating time means the start of evaluations). The statistical analyses performed were correlation matrix and canonical analysis. The canonical correlation analysis indicated that when the concentrations of attributes increase, the hydraulic performance of the drippers decreases. The interaction of this group of attributes indicates that the clogging of drippers operating with the five dilutions of aquaculture effluent in well water occurs by the combined action of physical, chemical, and biological agents. The ST dripper was the least sensitive to the group of quality attributes of the dilutions, whereas the most sensitive was the SL dripper. variables cloggingcausing causing nonpressure non pressure splitsplitplot split plot replicates 1 100 2 75 25 3 50 4 5 water, , water) subplots sub 1.6 16 6 (1. h1, h1 h h-1 1.7 17 7 h-1)) subsubplots 0, (0 8 evaluations. evaluations . evaluations) increase decreases physical chemical agents 10 1.

RESUMO A correlação canônica é usada para correlacionar grupos de variáveis distintas. O objetivo deste estudo foi utilizar análise de correlação canônica para avaliar a interação entre atributos de qualidade da água causadores de entupimento e o desempenho hidráulico de gotejadores não autocompensantes operando com diluições de efluente de aquicultura em água de poço. O experimento foi conduzido em delineamento inteiramente casualizado, em esquema de parcelas subsubdivididas, com três repetições, com cinco diluições nas parcelas (Diluição 1: 100% de efluente de aquicultura; Diluição 2: 75% de efluente de aquicultura + 25% de água de poço; Diluição 3 : 50% efluente de aquicultura + 50% água de poço; Diluição 4: 25% efluente de aquicultura + 75% água de poço; e Diluição 5: 100% água de poço), três emissores nas subparcelas (ST (1,6 L h-1) , SL (1,6 L h-1) e NJ (1,7 L h-1)), e três tempos de operação nas subsubparcelas (início do experimento, 80 e 160 horas, em que 0 horas de operação significa o início das avaliações). As análises estatísticas realizadas foram matriz de correlação e análise canônica. A análise de correlação canônica indicou que quando as concentrações dos atributos aumentam, o desempenho hidráulico dos gotejadores diminui. A interação desse grupo de atributos indica que o entupimento dos gotejadores que operam com as cinco diluições de efluente de aquicultura em água de poço ocorre pela ação combinada de agentes físicos, químicos e biológicos. O gotejador ST foi o menos sensível ao grupo de atributos de qualidade das diluições, enquanto o mais sensível foi o gotejador SL. distintas casualizado subsubdivididas repetições 1 100 2 75 25 50 4 5 poço, poço) 1,6 16 6 (1, h1 h h-1 1,7 17 7 h1, h-1)) 8 avaliações. avaliações . avaliações) aumentam diminui físicos biológicos 10 1, (1 h- (

Abstract Aim To understand the distribution of fish species and their use of habitat, a range of environmental variables were evaluated as predictors of fish assemblage composition and richness in tropical semiarid aquatic systems. Methods We surveyed the species composition of fish assemblages in semiarid aquatic systems and established their degree of association with the structure of the aquatic habitat. Sites consisted of stream reaches with surface water flow, isolated temporary pools, and man-made reservoirs. Fish sampling was conducted on four occasions during the wet (April and June 2006) and dry seasons (September and December 2006). The correlation between richness and abundance with the habitat structure was evaluated using stepwise multiple regression. Patterns of variation in fish assemblage composition across sites were evaluated using Nonmetric Multidimensional Scaling, and the Indicator Species Analysis was used to determine which species were significant indicators of sites. To establish multivariate correlations and test the hypothesis of local fish composition being associated with the environmental variables we used a Canonical Correspondence Analysis. Results Morphometric variables, stream reach width, stream length and elevation explained 75.6% of the variation in fish richness. Macrophyte cover and overhanging vegetation added to the predictive power of the model equation, where the final model explained 86.9% of the variation in fish richness. Canonical Correspondence Analysis showed a significant relationship between fish composition data and site morphology (altitude, bank slope and littoral depth). Among the water quality, habitat composition and substrate variables, temperature, sand, and gravel showed higher correlation with the CCA axes. Conclusions These results indicated that fish communities assume different structures and compositions across different habitat types following the environmental heterogeneity in dryland aquatic systems. flow pools manmade man made reservoirs April 2006 September 2006. . regression Scaling width 756 75 6 75.6 equation 869 86 9 86.9 altitude, altitude (altitude depth. depth depth) quality temperature sand axes 200 7 75. 8 86. 20 2

Resumo Objetivo Para entender a distribuição das espécies de peixes e seu uso do habitat, uma série de variáveis ambientais foi avaliada como preditoras da composição e riqueza de assembleias de peixes em sistemas aquáticos semiáridos tropicais. Métodos Nós avaliamos a composição de espécies de peixes em sistemas aquáticos semiáridos e estabelecemos seu grau de associação com a estrutura do habitat aquático. Os locais amostrados consistiram em trechos de riachos temporários com fluxo de água superficial, poças temporárias isoladas e reservatórios artificiais. A amostragem de peixes foi realizada em quatro ocasiões durante as estações úmida (abril e junho de 2006) e seca (setembro e dezembro de 2006). A correlação entre riqueza e abundância com a estrutura do habitat foi avaliada utilizando regressão múltipla. Os padrões de variação na composição da comunidade de peixes entre os locais foram avaliados utilizando Escalonamento Multidimensional Não-Métrico, e a Análise de Espécies Indicadoras foi utilizada para determinar quais espécies eram indicadoras significativas dos locais. Para estabelecer correlações multivariadas e testar a hipótese de que a composição local de peixes está associada às variáveis ambientais, utilizamos uma Análise de Correspondência Canônica. Resultados A regressão múltipla mostrou que as variáveis morfométricas, largura do trecho do riacho, comprimento do riacho e elevação explicaram 75,6% da variação na riqueza de peixes. A cobertura de macrófitas e a vegetação marginal adicionaram ao poder preditivo do modelo da equação, onde o modelo final explicou 86,9% da variação na riqueza de peixes. A Análise de Correspondência Canônica mostrou uma relação significativa entre os dados de composição de peixes e a morfologia dos locais amostrados (altitude, inclinação da margem e profundidade litorânea). Dentre as variáveis de qualidade da água, composição do habitat e substrato, a temperatura, areia e cascalho apresentaram maior correlação com os eixos da CCA. Conclusões Esses resultados indicaram que as comunidades de peixes assumiram diferentes estruturas e composições nos diferentes tipos de habitat de acordo com a heterogeneidade ambiental em sistemas aquáticos de regiões secas. tropicais aquático superficial artificiais abril 2006 setembro 2006. .

We report an ab initio study on the kinetics and chemical dynamics of the CH4 + CH reaction using a coupled cluster based composite scheme that includes unrestricted coupled cluster singles and doubles with perturbative connected triples method, UCCSD(T), energies extrapolated to the complete basis set limit, in addition to core-valence, higher-order correlation, and relativistic corrections. With this protocol, the reaction enthalpies for the two main reaction channels, C2H4 + H and CH2 + CH3, are reproduced with an absolute deviation of 0.04 kcal mol–1 relative to experimental data. At the UCCSD(T)/complete basis set (CBS) level of theory, the formation of the C2H5 intermediate is barrierless, in contrast with the low submerged barrier (–1.87 kcal -mol–1 relative to the reactants) found at the UCCSD(T)/augmented correlation-consistent polarized double-zeta (aug-cc-pVDZ) level of theory. With the correlation-consistent polarized triple-zeta (cc-pVTZ) basis set, we describe structural variations for the reaction bottleneck along the reaction path, finding at least three canonical variational transition states for the temperature range from 20 to 800 K. The thermal rates were obtained via the canonical unified statistical theory (CUS), using the canonical variational transition state theory (VTST) for the inner-transition state and long-range transition state theory (LRTST) for the outer-transition state. Our calculations agree with literature measurements and show inverse Arrhenius behavior, as observed experimentally. At 298 K, the computed rate constant is 2.65 × 10–10 cm3 molecule–1 s–1 and reported experimental measurements range from 2.5 × 10–12 to 3.0 × 10–10 cm3 molecule–1 s–1. Our theoretical study represents an improvement on previous computational investigations and highlights that even relatively simple gas-phase reactions can require high levels of theory to be modeled accurately. method UCCSDT, UCCSDT UCCSD T , UCCSD(T) limit corevalence, corevalence core valence, valence core-valence higherorder higher order correlation corrections protocol channels C C2H CH3 004 0 04 0.0 mol1 mol 1 mol– data UCCSDT/complete UCCSDTcomplete /complete CBS (CBS barrierless –1.87 187 87 (–1.8 -mol– reactants UCCSDT/augmented UCCSDTaugmented /augmented augmented correlationconsistent consistent doublezeta double zeta augccpVDZ aug cc pVDZ (aug-cc-pVDZ triplezeta triple ccpVTZ pVTZ (cc-pVTZ path 2 80 K CUS, CUS (CUS) VTST (VTST innertransition inner longrange long LRTST (LRTST outertransition outer behavior experimentally 29 265 65 2.6 1010 10 10–1 cm molecule1 molecule molecule– s1 s s– 25 5 2. 1012 12 30 3 3. gasphase gas phase accurately UCCSD(T 00 0. –1.8 18 8 (–1. -mol (CUS 26 6 101 10– –1.

ABSTRACT Introduction: Socio-demographic variables and oral pathologies influence nutritional status. Objective: To describe the relationship between socio-demographic characteristics, nutritional status, and oral health. Methods: In 2022, a descriptive observational study was conducted on 24 adult males, between 31 and 62 years old, from Yaguajay, Sancti Spíritus. Questionnaires, anthropometric measurements, and oral examinations were applied. In SPSS version21, the variables were summarized using absolute and relative frequencies, mean and standard deviations, as appropriate. Non-linear canonical correlation analysis was used for the multivariate analysis. Results: In the first dimension, the variables with saturations ≥0.5 that showed associations were: age group, educational level, body mass index, teeth lost due to caries and total teeth lost. In the second dimension, the variables that showed associations were: waist circumference and teeth lost due to caries. Adults aged 50 years or older presented losses of 10 or more teeth. The association between caries loss of 10 or more teeth and waist circumference of 102 cm or more was verified. 71% of the subjects with basic secondary school level were overweight. 55% and 67% of those with pre-university and university level respectively showed an acceptable body mass index. Conclusions: The associations reported between socioeconomic, nutritional and intraoral variables point to the importance of integrative health education and promotion. Multidisciplinary and common strategies could be more effective in the prevention of oral and nutritional diseases.

Abstract Objective This study aimed to validate the integrated correlation between the buccal bone and gingival thickness of the anterior maxilla, and to gain insight into the reference plane selection when measuring these two tissues before treatment with implants. Methodology Cone beam computed tomography (CBCT) and model scans of 350 human subjects were registered in the coDiagnostiX software to obtain sagittal maxillary incisor sections. The buccal bone thickness was measured at the coronal (2, 4, and 6 mm apical to the cementoenamel junction [CEJ]) and apical (0, 2, and 4 mm coronal to the apex plane) regions. The buccal gingival thickness was measured at the supra-CEJ (0, 1mm coronal to the CEJ) and sub-CEJ regions (1, 2, 4, and 6 mm apical to the CEJ). Canonical correlation analysis was performed for intergroup correlation analysis and investigation of key parameters. Results The mean thicknesses of the buccal bone and gingiva at different levels were 0.64~1.88 mm and 0.66~1.37 mm, respectively. There was a strong intergroup canonical correlation between the thickness of the buccal bone and that of the gingiva (r=0.837). The thickness of the buccal bone and gingiva at 2 mm apical to the CEJ are the most important indices with the highest canonical correlation coefficient and loadings. The most and least prevalent subgroups were the thin bone and thick gingiva group (accounting for 47.6%) and the thick bone and thick gingiva group (accounting for 8.6%). Conclusion Within the limitations of this retrospective study, the thickness of the buccal bone is significantly correlated with that of the buccal gingiva, and the 2 mm region apical to the CEJ is a vital plane for quantifying the thickness of these two tissues maxilla implants CBCT (CBCT 35 sections (2 [CEJ] 0, 0 (0 supraCEJ supra subCEJ sub 1, 1 (1 CEJ. . parameters 064188 64 88 0.64~1.8 066137 66 37 0.66~1.3 respectively r=0.837. r0837 r r=0.837 837 (r=0.837) loadings accounting 47.6% 476 47 8.6%. 86 8.6% 8 8.6%) 3 ( [CEJ 06418 0.64~1. 06613 0.66~1. r083 r=0.83 83 (r=0.837 47.6 8.6 0641 0.64~1 0661 0.66~1 r08 r=0.8 (r=0.83 47. 8. 064 0.64~ 066 0.66~ r0 r=0.

ABSTRACT Genetic diversity is important for conservation and genetic improvement of common beans. This study aimed to estimate the genetic diversity among common bean genotypes from the Embrapa germplasm collection using univariate and multivariate analyses. The experiment was conducted in the region of Aquidauana-MS, at the State University of Mato Grosso do Sul, in a randomized block design with three replications and twenty-three genotypes, in 2021. The agronomic traits considered in the study were plant height, height to first pod, number of branches, number of pods per plant, number of grains per pod, hundred-grain mass, and grain yield. Descriptive analysis, univariate and multivariate variance analyses, mean clustering, phenotypic correlation network, UPGMA analysis (Unweighted Pair Group Method with Arithmetic Mean), and canonical variables were used to examine the data.

ABSTRACT. This study investigates the meteorological variables exerting the most significant influence on the growth and productivity of four tomato hybrids cultivated for industrial processing in the Brazilian Savannah of Goiás State. Data on morphological and meteorological variables were collected in five locations (Hidrolândia, Itaberaí, Palmeiras de Goiás, Piracanjuba, and Silvânia) during the year 2020. Morphological characteristics assessed included plant height, number of branches, and leaf area index (LAI). Meteorological variables considered were average air temperature, global solar irradiance, thermal sum, and soil water availability. Pearson correlations, canonical correlations, and multivariate Stepwise regression were employed to analyze the relationships between morphological and meteorological variables. The study revealed that soil water availability significantly impacts tomato crop development, indicating the need for improved irrigation management. Adequate irrigation management contributed to an 86.1% increase in plant height and a 79.7% boost in leaf area index, while average air temperature influenced a 34% increase in the number of branches. In conclusion, proper irrigation management is crucial for enhancing tomato crop growth and development and optimizing water use.

Abstract. Marine mollusks provide important ecosystem services. They create habitats for benthic organisms, filter water, biodeposit organic carbon in the seafloor, and serve as food sources for other organisms. Studies of mollusk diversity require time-consuming methods to process samples and identify species. Thus, it is not surprising that most studies have focused on macromollusks that can be collected and processed easily, ignoring micromollusk species. Without understanding the ecology and distributions of micromollusks properly, it is impossible to assess their populations and implement adequate conservation measures. Here we present microgastropods collected in Bahia de los Angeles at the family level for September 2013 (summer) and February 2014 (winter). During each season, we sampled 6 coastal sediment stations, and analyzed depth, salinity, temperature, granulometry, and organic matter. A total of 20,353 specimens were collected: 15,310 in summer and 5,043 in winter. Seven micromollusk families were identified: Barleeidae, Caecidae, Cerithiidae, Eulimidae, Pyramidellidae, Rissoidae, and Tornidae. Caecidae and Barleeidae exhibited the highest densities among all families in summer and winter, respectively (278,044 ind·m-2, 142,222 ind·m-2). The lowest densities for summer and winter were observed for the Tornidae family (~1,867 ind·m-2, ~1,411 ind·m-2). Barleeidae, Caecidae, Cerithiidae, Rissoidae, and Tornidae were classified as herbivorous and detritivorous; Eulimidae and Pyramidellidae, as carnivorous and ectoparasitic. Tornidae and Eulimidae showed symbiotic relationships with various invertebrate species. The Bayesian analysis of variance indicated a high probability of differences only in summer (BF > 3). When comparing the stations in both periods, all stations, except station 6, showed differences between periods (BF > 3). The canonical correlation analysis indicated some associations between family abundances and temperature. This study provides valuable information that expands the knowledge of micromollusk biodiversity in the coastal area of Bahia de los Angeles, an important site for conservation in Mexico.

Resumen. Los moluscos marinos brindan importantes servicios ecosistémicos debido a que generan hábitats para organismos bentónicos, filtran agua, biodepositan carbono orgánico en el fondo marino y sirven como fuente de alimento para otros organismos. Los estudios de diversidad de moluscos requieren métodos de muestreo e identificación de especies muy tardados. Por lo tanto, no sorprende que la mayoría de los estudios se centren en los macromoluscos, los cuales son fácilmente recolectados y procesados, ignorando las especies de micromoluscos cuya identificación es difícil y tardada. Si no se comprende la ecología y distribución de los micromoluscos, es imposible evaluar sus poblaciones e implementar medidas de conservación. Aquí presentamos microgasterópodos recolectados en Bahía de los Ángeles a nivel de familia en 2 muestreos, en septiembre de 2013 (verano) y en febrero de 2014 (invierno). En cada temporada, muestreamos 6 estaciones costeras y realizamos mediciones de profundidad, salinidad, temperatura, granulometría y contenido de materia orgánica. Se recolectaron 20,353 ejemplares: 15,310 en verano y 5,043 en invierno. Se identificaron 7 familias: Barleeidae, Caecidae, Cerithiidae, Eulimidae, Pyramidellidae, Rissoidae y Tornidae. Caecidae y Barleeidae presentaron la máxima densidad en verano e invierno, respectivamente (278,044 ind·m-2, 142,222 ind·m-2). Tornidae presentó las densidades más bajas para verano e invierno (~1,867 ind·m-2, ~1,411 ind·m-2). Barleeidae, Caecidae, Cerithiidae, Rissoidae y Tornidae se clasificaron como herbívoros y detritívoros; Eulimidae y Pyramidellidae, como carnívoros y ectoparásitos. Tornidae y Eulimidae muestran relaciones simbióticas con varias especies de invertebrados. El análisis bayesiano indicó una alta probabilidad de diferencias para verano (BF > 3). Al comparar la misma estación entre muestreos, solo la estación 6 mostró diferencias entre periodos (BF > 3). Este estudio brinda información valiosa que amplía el conocimiento de la biodiversidad de micromoluscos en la zona costera de Bahía de los Ángeles, un importante sitio de conservación en México.

ABSTRACT The objective of this study was to check whether there is linear dependence between phenological, morphological and production traits and tassel traits in maize genotypes. Seven experiments were conducted with 16 maize genotypes, in a randomized block design, with three replicates. Four groups of traits were evaluated: phenological (two), morphological (three), production (four) and tassel (11). Joint analysis of variance and F test at 5% significance level were performed. The matrix of phenotypic correlation coefficients between the traits was estimated and multicollinearity was diagnosed in each group of traits. Associations between the groups of traits were checked by canonical correlation analysis. There is linear dependence between phenological, morphological and production traits and tassel traits in maize genotypes. Phenological (number of days from sowing to 50% of male flowering and number of days from sowing to 50% of female flowering), morphological (plant height and spike height) and production (number of spikes and grain yield) traits are positively associated with tassel traits (tassel branch number and tassel dry matter). Tassel branch number and tassel dry matter can be used for indirect selection of maize plants. genotypes 1 design replicates evaluated two, two , (two) three, (three) four (four 11. 11 .

RESUMO O objetivo deste estudo foi verificar se há dependência linear entre os caracteres fenológicos, morfológicos e produtivos com os caracteres de pendão em genótipos de milho. Foram conduzidos sete experimentos com 16 genótipos de milho, no delineamento experimental blocos ao acaso, com três repetições. Foram avaliados quatro grupos de caracteres: fenológicos (dois), morfológicos (três), produtivos (quatro) e de pendão (11). A análise de variância conjunta e o teste F a 5% de significância foram realizados. A matriz de coeficientes de correlação fenotípica entre os caracteres foi estimada e realizado o diagnóstico de multicolinearidade, em cada grupo de caracteres. As associações entre os grupos de caracteres foram verificadas por meio da análise de correlação canônica. Há dependência linear entre os caracteres fenológicos, morfológicos e produtivos com os caracteres de pendão em genótipos de milho. Os caracteres fenológicos (número de dias da semeadura até 50% do florescimento masculino e número de dias da semeadura até 50% do florescimento feminino), morfológicos (altura de planta e altura de inserção da espiga) e produtivos (número de espigas e produtividade de grãos) estão associados positivamente aos caracteres de pendão (número de ramificações e matéria seca do pendão). O número de ramificações e a matéria seca do pendão podem ser utilizados para seleção indireta de plantas de milho. milho 1 acaso repetições dois, dois , (dois) três, (três) (quatro 11. 11 .

With water quality deteriorating rapidly at a global scale, river sections suited to serve as reference sites are being increasingly lost. It thus becomes critical to develop rapid methods to confirm that previously monitored sites continue meet the requirements of reliable reference sites. In the absence of pristine sites, 9 near-natural sites, as defined by the Kleynhans (1996) classification, were used as reference sites for the Luvuvhu River catchment to compare the quality of physico-chemical factors against a biological metric. Baetid mayfly community structure at a site was chosen as an index of water quality, since this family is common in all types of freshwaters, highly diverse and adapted to unpolluted running water. Baetid larvae were sampled monthly from stones-in-current biotopes across 9 sites for over 1 year, between December 2016 and January 2018. A Spearman's correlation test was used to evaluate the relationship between physico-chemical factors and identify redundant variables. Water quality standards were measured against the national water quality guidelines for aquatic ecosystems. We used a generalized linear model to determine the effect of physico-chemical variables on baetid species, and canonical correspondence analysis to show the relationships between baetid species, sites, and physico-chemical variables. A total of 3 039 individuals belonging to 12 mayfly species were recorded. Our findings indicated that while the physico-chemical factors were highly variable, they were within favourable ranges to reflect reference site conditions. While water temperature was the most important driver of baetid community structure in general, as it negatively affected their abundances, a subset of species (Pseudoponnota sp., Pseudocloeon sp., Acanthiops varius and Demoulinia crassi) showed clear responses to changes in TDS and stream width. We conclude that specific baetid species show good potential as biological indicators of reference sites and chronic water temperature stress, making assessment of reference sites easier.
