Analysis of variance (ANOVA)-simultaneous component analysis (ASCA) is a method of choice for factorial design studies of environmental impacts on plant metabolomes and can be used to quantitatively carry out this comparative analysis. The impacts of seven mixture design extractor systems made up of ethanol, dichloromethane, and hexane and their 1:1 binary and 1:1:1 ternary solvents for several replicate experiments (n = 3, 4, 5) were assessed using ASCA models determined from Fourier-transform infrared (FTIR), near-infrared (NIR), and UV-Vis spectroscopic measurements on yerba mate leaf extracts. This analysis considered two-factor effects: secondary sexual dimorphism (male and female plants) and cultivation systems (monoculture and agroforestry), as well as their interaction effect. The three binary solvents were found to be more efficient extractor systems for all four detectors as they found 83 main and interaction effects significant at or above the 95% confidence level compared with only 47 for the pure solvent extracts. Binary solvent extracts resulted in averages between 44.04 and 86.61% for the ASCA total effect variances compared with 40.62 to 71.07% for pure extractors. Of the 60 significant effects found for experiments with 5 repetitions 53 or 88% were obtained with only triplicate determinations. The choice of spectroscopic technique and solvent system have large impacts on metabolomic analysis results.

ABSTRACT The purpose of this study was to analyze the influence of attention and skepticism in the evaluation of false market discourse with an environmental appeal (greenwashing). The theoretical support for the research was based on the study of the attention process (understood in terms of pre-attention and attention), as well as the practice of greenwashing and consumer skepticism. The methodological procedure adopted a hypothetical-deductive approach, carried out through two face-to-face experiments (n=129 and n=159) with a 2 factorial design (attention/pre-attention) x 2 (present/absent skepticism), with the measurement of four interest metrics (attribute evaluation, judgment about the practice of greenwashing, emotional reaction to the advertisement, and environmental purchase behavior), added to eye tracking. One-way ANOVA was used for one-dimensional analyzes and general linear model (GLM) ANOVA for multivariate analyses, with Tukey's post hoc test. As a result, it was possible to observe a better evaluation of the practice of greenwashing when pre-attentiveness and the absence of skepticism were combined, which sets up a potential scenario for the influence of this false marketing discourse on consumer behavior. greenwashing. .

RESUMO O trabalho teve como objetivo analisar a influência da atenção e do ceticismo na avaliação do falso discurso mercadológico com apelo ambiental (greenwashing). O suporte teórico da pesquisa assentou-se no estudo do processo da atenção (compreendido em termos de pré-atenção e atenção), assim como da prática de greenwashing e o ceticismo do consumidor. O procedimento metodológico adotou uma abordagem hipotético-dedutiva, realizada por meio de dois experimentos presenciais (n=129 e n=159) com desenho fatorial 2 (atenção/pré-atenção) x 2 (ceticismo presente/ausente), com a mensuração de quatro métricas de interesse (avaliação dos atributos, julgamento acerca da prática de greenwashing, reação emocional ao anúncio e comportamento ambiental de compra), somada ao monitoramento ocular (eyetracker). Foram empregadas a ANOVA one-way para as análises unidimensionais e a ANOVA pelo modelo linear geral (GLM) para as análises multivariadas, com o teste post hoc de Tukey. Como resultado, foi possível observar uma melhor avaliação da prática de greenwashing quando da junção da pré-atenção e da ausência do ceticismo, o que configura um cenário de potencialidade da capacidade de influência desse falso discurso mercadológico no comportamento do consumidor. greenwashing. .

ABSTRACT Unsustainable reclamation activities (URAs) have been increasingly conducted to respond to the rising global food demand, leading to severe repercussions on land environments. A total of 120 soil samples representing 12 sites were randomly selected in the three distinct land types (PMFs, PALs, and BHLs) to a depth of 60 cm. The impacts of URAs on soil properties and functions (SPFs) across the Nghe An mountainous province, Vietnam were assessed using the SPSS software (version 26.0) through a one-way analysis of variance (ANOVA). The findings indicated the distinct differences in soil particle size (SPS) among different land types (DLTs). Pristine and mixed forests (PMFs) exhibited the lowest sand ratios, ranging from 31.4 to 35.2%, while bare hills and lands (BHLs) recorded the highest sand ratios, ranging from 49.7 to 55.1%. High bulk density (BD) was observed in BHLs (1.36 ± 0.07 kg dm-3) and PMFs (0.89 ± 0.02 to 1.13 ± 0.03 kg dm-3) while perennial and annual lands (PALs) varied from 1.17 ± 0.04 to 1.25 ± 0.08 kg dm-3. PMFs showed low values for total soil porosity (TSP), and soil water content (SWC) with respective ranges of 32.97-36.18% and 4.72-6.15% while PALs and BHLs exhibited high values for TSP (39.25-43.19%; 43.97-49.62%), and SWC (7.39-10.07%; 9.98-12.74%). Cation exchange capacity (CEC), Ca2+, K+, and Mg2+ were recorded higher in PALs compared to PMFs and PALs while total organic contents (TOCs) detected little variation among DLTs. Overall, the URAs enhanced the adverse effects on the SPFs across the study area. (URAs demand environments 1 PMFs, (PMFs 6 cm (SPFs province version 26.0 260 26 0 oneway one way ANOVA. ANOVA .

RESUMO As atividades de recuperação insustentáveis (URAs) têm sido cada vez mais realizadas para responder à crescente procura global de alimentos, levando a graves repercussões nos ambientes terrestres. Um total de 120 amostras de solo representando 12 locais foram selecionadas aleatoriamente nos três tipos distintos de terra (PMFs, PALs e BHLs) a uma profundidade de 60 cm para avaliar os impactos das URAs na província de Nghe An Mountain, no Vietnã. A análise estatística dos parâmetros do solo foi realizada no software SPSS (versão 26.0) por meio de análise de variância unidirecional (ANOVA). As descobertas indicam diferenças distintas no tamanho das partículas do solo (SPS) entre os diferentes tipos de terreno (DLTs). Florestas virgens e mistas (PMFs) exibiram as menores proporções de areia, variando de 31,4 a 35,2%, enquanto colinas e terras nuas (BHLs) registraram as maiores proporções de areia, variando de 49,7 a 55,1%. Elevado densidade global (BD) foi observado em BHLs (1,36 ± 0,07 kg dm-3) e PMFs (0,89 ± 0,02 a 1,13 ± 0,03 kg dm-3) enquanto terras perenes e anuais (PALs) variaram de 1,17 ± 0,04 a 1,25 ± 0,08 kg dm-3. Os PMFs apresentaram baixos valores de porosidade total do solo (TSP) e teor de água do solo (SWC) com respectivas faixas de 32,97-36,18% e 4,72-6,15% enquanto PALs e BHLs exibiram valores elevados para TSP (39,25-43,19%; 43,97-49,62%). e SWC (7,39-10,07%; 9,98-12,74%). A capacidade de troca catiônica (CEC), Ca2+, K+ e Mg2+ registrou altos valores nos PALs em comparação aos PMFs e PALs, enquanto o conteúdo orgânico total (TOCs) detectou pouca variação entre os DLTs. No geral, as URAs aumentaram os efeitos adversos nas propriedades e funções do solo (SPFs) em toda a área de estudo.

ABSTRACT Introduction: the postgraduate educational climate (CE) in the hospital environment can determine the way in which resident physicians (MRs) adapt to their new stage, during which professional burnout syndrome (PAS) is highly likely to occur at some point. Objective: to determine the relationship between the educational climate and professional burnout in physicians in the medical residency programs of the National Hospital 2023-2024. Methodology: cross-sectional observational study of a sample of MR convenience of both sexes from all medical specialties of the National Hospital between November 2023 and January 2024, MR with external rotation and/or vacations were excluded. Sample calculation; 136 MR. An online form from Google was sent to the MR email requesting voluntary participation. The SAP was measured with the standard Maslach Burnout Inventory (MBI) method with subscales; emotional exhaustion (EA), depersonalization (DESP), personal fulfillment (PR), with PAS with high scores of AE, DESP and low RP. The EC was assessed with the measure of the hospital postgraduate educational environment (PHEEM) with subscales; perception of role autonomy (PAR), perception of teaching (PE), perception of social support (PSS), the higher the score, the better the EC. Demographic and academic variables, MBI and PHEEM scores were collected, and the SAP was considered dependent, as the main result was the predictive relationship of the PHEEM on the SAP. Data were compared with χ², t-test or Mann-Whitney U, ANOVA and linear regression (p-significant value =<0.05). Results: of 233 participants, the mean age was 28.75 (±2.20), 63.94 % (149) women, the general prevalence of PAS; 70.38 % (164/233), PAS in men 75 % (63/84) and women 67.78 % (101/149) p=0.0014, the first 2 years with the highest frequency of PAS; 65 (85.52 %), 59 (86.76 %) respectively p=0.0009, 63 (90 %) p=0.0071 surgical specialties. The subscales of the MBI, the AE; 79.82 % (186) with an average of 35.39 (± 11.61) points. The CE of MRs with SAP; 107.9 (19.6) dots and without PAS; 136.3 (12.1) dots 95 % CI 18.1-25.0 p= 0.0001. The PHEEM predicted the AE with R2=0.619, B= -0.18 (±0.009) p=0.001, and the DESP; R2= 0.385, B= -0.001(0.004) p=0.009, PSS being a significant predictor with inverse correlation in both. Conclusion: there is an inverse relationship between the educational climate and burnout syndrome in the population studied, with a high prevalence of burnout in male residents of surgical specialties, with the social support of the hospital educational environment being a significant predictor for the development of burnout syndrome.

ABSTRACT Agonoscena pistaciae (Hemiptera: Psyllidae) is a significant pest in pistachio (Pistacia vera L.) orchards in Türkiye. This study aimed to evaluate the effectiveness of yellow sticky traps as an alternative method for controlling A. pistaciae populations in pistachio orchards. Conducted in late September and early October of 2021 and 2022, during peak pest activity, the experiment was carried out in Siirt, with three replicates following a randomized block design. Five traps were hung on all sides of each tree for sampling. Repeated measures ANOVA (repeated measures; general linear model) was used to observe changes over time. The results indicated that yellow sticky traps were highly effective in mass trapping adults, capturing an average maximum of 12 332.67 adults per trap. A significant decrease in the number of nymphs and eggs on the leaves was observed in the yellow sticky trap-treated trees compared to the control plots by mid-October (P < 0.05). Specifically, the average number of nymphs per composite leaf dropped from 24.95 to 11.23 in 2021, and from 145.18 to 27.29 in 2022. Similarly, the average number of eggs per composite leaf decreased from 61.18 to 2.29 in 2021, and from 73.56 to 3.64 in 2022. These findings suggest that yellow sticky traps can significantly reduce psyllid populations in pistachio orchards over the long term and can be an effective control method when used early in the vegetative period for low- to medium-sized psyllid populations.

Abstract Introduction. Livestock farming with Creole cattle is practiced in rural areas with challenging characteristics for species management. Objective. To describe the production system and the socio-cultural and technical-economic factors affecting the production of Nunkiní Creole cattle (Bos taurus). Materials and methods. The study was conducted from November 2020 to October 2021 in nine livestock production units of Nunkiní, Calkiní municipality, Campeche, Mexico. Information was obtained from an interview form with social, cultural, technical, and economic study variables, applied to selected producers. Data were analyzed using descriptive statistics and ANOVA. Results. Livestock farming was carried out by men (100 %), with an average age of 58.44 years. The average years of experience were 34.61. Younger producers had higher levels of education and less experience, and were responsible for the production units of higher technological levels. The size of the livestock production unit ranged from five to twenty-two cattle (average of 14). Feeding management followed a transhumance scheme, with cattle being free-ranging on ejido lands and from May to December and semi-stabled from January to April, grazing on cultivated pastures and supplemented with agricultural residues. With the zootechnical management implemented by the producers, an average pregnancy rate of 83 % was achieved. The main product marketed was fresh meat in cuts and direct sale to consumers, with an average price of 2.675 USD$/kg. Conclusion. It is traditional extensive system that takes advantage of the common use of grasslands. It involves experienced but older producers, with small investments, and serves to strengthen their family economy. This activity is threatened by the lack of revaluation of Creole cattle and the introduction of exotic breeds in the area to maximize production.

Resumen Introducción. La ganadería con bovinos criollos se práctica en espacios rurales con características difíciles para el manejo de las especies. Objetivo. Describir el sistema productivo y los factores socioculturales y técnico-económicos que afectan la producción del bovino criollo de Nunkiní (Bos taurus). Materiales y métodos. El estudio se realizó entre noviembre del 2020 a octubre del 2021, en nueve unidades de producción pecuarias de Nunkiní en el municipio de Calkiní, Campeche, México. La información se obtuvo de una cédula de entrevista con variables de estudio sociales, culturales, técnicas y económicas, aplicada a productores seleccionados. Los datos se analizaron mediante estadística descriptiva y ANDEVA. Resultados. La crianza del ganado la realizaron hombres (100 %), con edad promedio de 58,44 años. Los años de experiencia promedio fueron de 34, 61. Los productores jóvenes tuvieron mayor escolaridad y menor experiencia, y se encargaron de las unidades de producción de mayor nivel tecnológico. El tamaño de la unidad de producción pecuaria varió de cinco a veintidós bovinos (media de 14). El manejo alimenticio tuvo un esquema de trashumancia, donde de mayo a diciembre estuvieron libres en tierras ejidales y de enero a abril se manejaron semiestabulados, con pastoreo en potreros cultivados y suplementados con residuos agrícolas. Con el manejo zootécnico implementado por los productores, se obtuvo un promedio de 83 % de preñez. El producto principal comercializado fue carne fresca en cortes y venta directa al consumidor, con un precio promedio de 2,675 USD$/kg. Conclusión. Es un sistema tradicional extensivo que aprovecha el uso común de los agostaderos. Con productores de experiencia, pero de edad avanzada, de pequeña inversión y le sirve para fortalecer su economía familiar. Dicha actividad se ve amenazada por la falta de revalorización del bovino criollo y la introducción de razas exóticas en la zona para maximizar la producción.

Abstract Introduction. Estimating crop evapotranspiration (ETc) helps determine water requirements, enabling the proposal of irrigation techniques that save water. Objective. To use remotely piloted aircraft system (RPAs) for greater precision in measuring evapotranspiration in rice fields, aiming to reduce water consumption. Materials and methods. The study utilized a randomized complete block design with a factorial structure of two experiments: flooded irrigation (E1) and irrigation with controlled drying (E2), and three rice varieties (IR43, IR71706, Sahod Ulan 12). The study was conducted at the Experimental Irrigation Area (AER) of the Universidad Nacional Agraria La Molina, Peru. Eight RPAS flights were carried out between January and February 2019, distributed between the tillering and cotton point stages. Results. The combined analysis of treatments using analysis of variance (ANOVA) and Duncan’s test with p < 0.05 revealed a significant difference in ETc between E1 and E2. However, no significant difference was found between the rice varieties. Maximum values of ETc and yield were obtained for E1 at 4.50 mm/day and 10389 kg/ha, and for E2 at 3.7 mm/day and 9710 kg/ha, respectively. Conclusions. The use of a remotely piloted aircraft system improved the temporal and spatial resolution of multispectral and thermal images, providing greater accuracy in crop evapotranspiration (ETc) under two irrigation regimes. Controlled drying irrigation resulted in a A 24% reduction in ETc, allowing for a water saving of 855 m3/ha.

Abstract Introduction. Endophytic fungi (EF) in grapevines (Vitis vinifera) have great potential for agricultural applications and may represent possible biological control agents for vineyards. Objective. To isolate and identify endophytic fungi (EF) from grapevine plants with antibiosis capacity against Botrytis cinerea. Materials and methods. Young and mature branches from forty healthy grapevine plants were collected from seven production lots in the Cañete province, Lima, Peru, during March to May 2022. EF isolation was performed on 702 sections of disinfected tissues using potato dextrose agar (PDA) culture medium, and identification was carried out at the genus level. Secondary metabolites were extracted from twenty-eight EF strains to determine the mycelial inhibition of the pathogen. An analysis of variance (ANOVA) was conducted on the evaluated parameters using the Minitab statistical program. Results. A total of 129 EF strains were isolated from leaves and stems of young and mature grapevine branches, encompassing seven genera (Trichoderma, Aspergillus, Alternaria, Cladosporium, Fusarium, Nigrospora, and Stemphylium). The highest frequency was found in leaves and mature branches. Trichoderma and Alternaria were the most frecuent genera in grapevine plants, with 22.48 % and 21.71%, respectively. Metabolites obtained from the EFVH-01 strain of the genus Cladosporium, and EF-99 and EF-70 strains of the genus Alternaria, had the greatest effect on mycelial inhibition of the pathogen. Conclusions. Strains of endophytic fungi from the genera Cladosporium and Alternaria showed antibiosis capacity against Botrytis cinerea at the laboratory scale, which could potential biocontrol agents of pathogens in grapevine cultivation.

Abstract The purpose of this research is to analyze the classification of female university students based on their unfaithful behavior, describing each category by their communication styles as a couple and sexual behavior. 454 university women aged 18 to 28 years participated (x̄ = 20.28; σ = 1.785). Each variable was measured with valid and reliable instruments. A multivariate analysis was carried out with the infidelity variable, identifying three groups: “Desire for a romantic bond”, “fidelity” and “non-fidelity”. An ANOVA was used to contrast the three groups, finding differences according to the variables couple communication and sexual behavior. It is concluded that the “not-fidelity” group is more socially receptive and communicates positively and kindly with their partners, demonstrating fewer seductive behaviors; the “Desire for a romantic bond” group shows a negative communication style with their partners, and greater sexual behavior; and the “fidelity” group shows more seduction behaviors than the other two groups.

Abstract (Objective) Genetic literacy relates to knowledge and skills in utilizing genetic principles for solving various problems or issues related to genetics. Genetic literacy is an essential ability for students to master, as it is related to various current issues, especially in the fields of health and agriculture. However, research on genetic literacy has not been properly developed from different perspectives, including those related to academic level and gender. Therefore, to fill this gap, the present research seeks to measure the genetic literacy of Indonesian high school students in relation to their academic level and gender. (Methodology) Data were collected using an analytic observational cross-sectional study. The research participants were 1102 students from 55 senior high schools in Indonesia. The participants took a test, which had been evaluated for validity and reliability. The data was then analyzed using ANOVA, and the participants’ genetic literacy levels were categorized as adequate or inadequate. (Results). The study showed that students’ genetic literacy was relatively inadequate. While academic level was significantly related to students’ genetic literacy, gender was not. (Conclusions) The results of this study indicate that the academic level has a significant effect on the level of students’ genetic literacy, while gender does not. The findings support the conclusion that genetic literacy needs to be considered in education, and that it is necessary that teachers and schools design appropriate strategies to empower and increase students’ genetic literacy in high school settings.

Abstract Background: Maize landraces show remarkable diversity and environmental adaptability in Mexico. Nevertheless, few studies have explored physiological mechanisms used by different maize landraces to grow and yield in a particular agroecological region. Question: How do three landrace maize populations from contrasting maize races in southeastern Mexico, differ in their responses in terms of growth, chlorophyll fluorescence, and gas exchange? Studied species: Zea mays L. Study site and date: Yucatan, Mexico; 2017. Methods: The field experiment followed a complete randomized block design, with six replicates. Three contrasting maize landraces were evaluated as treatments. Response variables were vegetative traits, dry matter allocation, yield components, and maize physiological responses. Data were analyzed by one-way ANOVA and post hoc Tukey multiple comparison test (P ≤ 0.05). Results: Maize landraces showed differences in cycle length, plant morphology, and yield performance. The long cycle maize landrace Xnuc-naal, had tall plants that accumulated 17 and 21 % more dry matter than Xmejen-naal and Elotillo, respectively. The short-cycle maize landraces Elotillo and Xmejen-naal exhibit superior physiological responses leading to higher grain yields compared to the Xnuc-naal. Conclusions: The landrace Xnuc-naal stood out for its ability in forage production, whereas Elotillo and Xmejen-naal exhibited notable physiological efficiency in grain production in southeastern Mexico.

Conclusiones: La variedad de maíz Xnuc-naal destacó por su capacidad para la producción de forraje, mientras que Elotillo y Xmejen-naal demostraron una eficiencia fisiológica notable en la producción de grano en el sureste de México.

SUMMARY: The aim of the study is to investigate the differences in body composition between differently trained men and women. This research included 159 participants (84 male and 75 female) divided into 5 groups according to activity level: PI - physically inactive, PA - physically active, SP - strength and power athletes, EA - endurance athletes, TS - team sports athletes. The testing procedure of measuring body composition was carried out by the use of bioelectrical impedance analysis (BIA, InBody 720). Of the statistical analysis, ANOVA and MANOVA were used. The results showed that there is a significant difference in body composition parameters between differently trained men and women (p = 0.000; F = 2.470; η2 = 0.356, on average). Both in groups of men and women the biggest differences were observed between PI, EA and other groups (F = from 9.656 to -1.673, p = from 0.000 to 0.043; F = from 10.966 to 1.073, p = from 0.000 to 0.050, respectively). The results showed that every physical activity is beneficial from the aspect of body composition status and that the most crucial factor in improving body composition status is the regularity of physical activity. It has been shown that regular physical activity leads to a decrease in muscle fat and an increase in muscle mass and protein. Also, it has been shown that practicing a physical activity typical for endurance sports has the most significant positive impact on body composition status and leads to a significant decrease in body fat mass.

RESUMEN: El objetivo del estudio fue investigar las diferencias en la composición corporal entre hombres y mujeres con entrenamiento diferente. Esta investigación incluyó a 159 participantes (84 hombres y 75 mujeres) divididos en 5 grupos según el nivel de actividad: FI - físicamente inactivos, FA - físicamente activos, FP - atletas de fuerza-potencia, AR - atletas de resistencia, DE - atletas de deportes de equipo. El procedimiento de prueba para medir la composición corporal se llevó a cabo mediante el análisis de impedancia bioeléctrica (BIA, InBody 720). Para el análisis estadístico se utilizaron ANOVA y MANOVA. Los resultados mostraron que existe una diferencia significativa en los parámetros de composición corporal entre hombres y mujeres con entrenamiento diferente (p = 0,000; F = 2,470; η2 = 0,356, en promedio). Tanto en los grupos de hombres como en los de mujeres las mayores diferencias se observaron entre FI, AR y otros grupos (F = de 9,656 a -1,673, p = de 0,000 a 0,043; F = de 10,966 a 1,073, p = de 0,000 a 0,050, respectivamente). Los resultados mostraron que toda actividad física es beneficiosa desde el punto de vista del estado de la composición corporal y que el factor más crucial para mejorar el estado de la composición corporal es la regularidad de la actividad física. Se ha demostrado que la actividad física regular provoca una disminución de la grasa muscular y un aumento de la masa muscular y las proteínas. Además, se ha demostrado que la práctica de una actividad física típica de los deportes de resistencia tiene el impacto positivo más significativo en el estado de la composición corporal y conduce a una disminución significativa de la masa grasa corporal.

BACKGROUND: Students' perceptions of the educational methodology are valuable for improving the quality of the educational environment. However, there is limited literature on students' perceptions of lectures and peer-assisted learning (PAL) within the School of Biomedical and Allied Health Sciences OBJECTIVES: To determine the perceptions of allied health students across different study levels regarding the effectiveness of lectures and PAL as educational strategies METHODS: This cross-sectional study involved 213 Allied Health students from levels 200 to 400 at the University of Ghana. Data were collected using an adopted perceptions questionnaire. Perceptions of lectures and PAL were analysed using means and mean percentages. A one-way ANOVA test was performed to compare differences in perceptions among students at various study levels, while the independent sample t-test was used to compare differences in perceptions between male and female students RESULTS: PAL had the highest mean scores, with a global rating of 4.1 (standard deviation (SD) 0.8) compared with 3.5 (SD 0.8) for lectures (p<0.00). There were no differences in perceptions about lectures and PAL among levels 200 to 400 students. Female students had a more positive perception of PAL, while both male and female students had the same positive perceptions about lectures CONCLUSIONS: Students generally had positive perceptions about lectures and PAL; however, PAL was acknowledged as an alternative that provides students with active educational experiences. PAL may be incorporated into the standard curriculum alongside lectures

Abstract Background: Plant species used for reforestation purposes are idoneous if native, and also if they are present in regeneration sources. High germination percentages under different light conditions and a broad phenological pattern enhance adaptability to environmental heterogeneity. Preference for species responsive to mycorrhizal inoculation is recommended. Questions: Is Solanum pubigerum a widespread species in temperate forests of central Mexico?, under which light conditions germination will be the highest?, how abundant is it in natural regeneration sources?, does inoculation with mycorrhizal fungi benefit its germination and growth? Studied species / data description / Mathematical model: Solanum pubigerum/distribution in central Mexico forests, germination and viability percentages, reproductive phenology, growth dependence on AM fungi/ Kruskal-Wallis test, synchrony, Spearman correlations, ANOVA. Study site and dates: Abies religiosa forest, Mexico City. August 2019 - July 2020. Methods: Seeds of S. pubigerum were exposed to different light qualities, their viability was monitored for two years. Its presence in natural regeneration sources was registered. Reproductive phenology was recorded, and seedlings were inoculated with arbuscular mycorrhizal fungi to assess their growth. Results: Highest seed germination occurred under white light conditions, with sustained viability after two years. The species was found in the seed bank across seasons, less abundantly in seed rain during the dry season. It exhibited extensive flowering and fruiting patterns. Mycorrhiza inoculation significantly boosted seed germination and growth. Conclusions: Solanum pubigerum is suitable for reforestation in central Mexico forests due to its high germination percentages and mycorrhizal responsiveness.

Abstract Introduction. Postpartum anxiety after childbirth is a common condition among pregnant women due to reasons such as the uncertainty of experiencing pregnancy and childbirth for the first time, or previous negative experiences. Fear of childbirth can affect the mother’s baby care process. Objective. This study was conducted analytically with a single-subject design to determine the effects of maternal concerns about childbirth and the postpartum period on obsessive and compulsive behaviors related to baby care. Materials and methods. The study was conducted with 260 mothers. Data were collected using a descriptive information form, and the scales ‘Fear of Childbirth and Postpartum Period’, and ‘Obsessive and Compulsive Behaviors of Mothers in the Postpartum Period Related to Baby Care’. The data were analyzed using the SPSS™ software to calculate percentages, mean values, t tests, ANOVA, Pearson’s correlation, and simple linear regression analysis. Results. A statistically significant and positive correlation was found between participant scores of the ‘Fear of Childbirth and Postpartum Period’ and the ‘Obsessive and Compulsive Behaviors of Mothers in the Postpartum Period Related to Baby Care’ scales (p < 0.01). The regression model showed that 18.0% of the total variance in the obsessive and compulsive behaviors of mothers in the postpartum was explained by the fear of childbirth and the postpartum period (corrected R2 = 0.180). Conclusions. Fear of childbirth and the postpartum period were moderate. However, as the fear of women regarding childbirth and the postpartum period increased, their postpartum obsessive and compulsive behaviors about baby care also increased.

Resumen Introducción. La ansiedad del parto y el posparto es una condición común entre las mujeres embarazadas por la incertidumbre de vivir el embarazo y el parto por primera vez o por previas experiencias negativas. El miedo al parto puede afectar el proceso del cuidado del bebé de la madre. Objetivo. Determinar el efecto de las preocupaciones maternas sobre el parto y el puerperio y su efecto sobre las conductas obsesivas y compulsivas relacionadas con el cuidado del bebé. Materiales y métodos. El estudio se realizó con 260 madres. Los datos fueron recolectados en el formulario de información descriptiva y se usaron la “Escala de miedo al parto y al período posparto” y la de “Comportamientos obsesivos y compulsivos de las madres en el período posparto relacionados con el cuidado del bebé”. Los datos fueron evaluados mediante el software SPSS™ mediante el cálculo de porcentajes, promedio, prueba t, ANOVA, correlación de Pearson y análisis de regresión múltiple. Resultados. Se encontró una correlación positiva y estadísticamente significativa entre la “Escala de miedo al parto y del período posparto” y la de “Comportamientos obsesivos y compulsivos de las madres en el período posparto relacionadas con el cuidado del bebé” (p < 0.01). En el modelo creado por análisis de regresión se observó que el 18,0% del cambio en la escala de comportamientos obsesivos-compulsivos estaba explicado por el miedo al parto y al puerperio (R2corregido = 0,180). Conclusiones. En el estudio se determinó que el miedo al parto y al puerperio era moderado. Sin embargo, a medida que aumentaba el puntaje de miedo al parto y al período posparto, también aumentaban los comportamientos obsesivos y compulsivos de las madres en el puerperio relacionados con el cuidado del bebé.
