Resumen (Objetivo) El objetivo del documento es verificar la estructura factorial de la Escala de Clima Escolar en Ambientes Universitarios (ECEAU) mediante modelos de ecuaciones estructurales (SEM). (Metodología) Se realizó un estudio transversal no experimental con una muestra aleatoria de 381 estudiantes de la Universidad Nacional de Costa Rica, a los que se le aplicó la ECEAU. Se planteó un modelo SEM para verificar la estructura factorial de la escala y un análisis factorial exploratorio (AFE) que brindó la base para proponer un modelo SEM alternativo con una estructura distinta. La confiabilidad de las escalas se determinó mediante el omega de McDonald y los criterios de bondad de ajuste para los modelos SEM fueron el RMSEA, el CFI, el TLI y el GFI. El análisis se efectuó con el software R. (Resultados) La confiabilidad de las escalas en ambos modelos resultaron adecuadas (w >0.70), aunque mejores en el modelo propuesto. El AFE sugirió una estructura diferente para la ECEAU, manteniendo algunas dimensiones de la estructura original y modificando y eliminando otras. Los indicadores de bondad de ajuste, en ambos modelos, fueron casi idénticos con RMSEA=0.02, CFI=0.99, el TLI=0.99 y GFI=0.98, lo que brinda evidencia a favor de las estructuras factoriales planteadas. (Conclusiones) Se verifica la estructura originalmente planteada en la ECEAU y las diferencias en los métodos de estimación y rotación generaron la propuesta de otra estructura factorial, igualmente válida, para medir el constructo clima escolar, en el contexto universitario estudiado y que puede ser aplicado a contextos similares.

Resumo (Objetivo) O objetivo do artigo é verificar a estrutura fatorial da Escala de Clima Escolar em Ambientes Universitários (ECEAU) usando modelagem de equações estruturais (SEM). (Metodologia) Foi realizado um estudo transversal não experimental com uma amostra aleatória de 381 alunos da Universidade Nacional da Costa Rica, aos quais foi aplicada a ECEAU. Uma modelagem SEM foi usada para verificar a estrutura fatorial da escala e uma análise fatorial exploratória (AFE) forneceu a base para a proposta de uma modelagem SEM alternativa com uma estrutura diferente.

A AFE sugeriu uma estrutura diferente para a ECEAU, mantendo algumas dimensões da estrutura original e modificando e eliminando outras. Os indicadores de adequação em ambos os modelos foram quase idênticos, com RMSEA=0,02, CFI=0,99, TLI=0,99 e GFI=0,98, o que fornece evidências a favor das estruturas de fatores propostas. (Conclusões) Confirmou-se a estrutura originalmente proposta no ECEAU e as diferenças nos métodos de estimativa e rotação geraram a proposta de outra estrutura fatorial, igualmente válida, para medir o construto clima escolar no contexto universitário estudado e que pode ser aplicada a contextos semelhantes.

Abstract (Objective) The aim of this paper is to verify the factorial structure of the School Climate Scale in University Environments (ECEAU) through structural equation models (SEM). (Methodology) A non-experimental cross-sectional study was carried out with a random sample of 381 students of the Universidad Nacional de Costa Rica (UNA), to whom the ECEAU was applied. A SEM model was proposed to confirm the factor structure of the scale and an exploratory factor analysis (EFA) was used to provide the basis for an alternative SEM model with a different structure. The reliability of scales was determined using McDonald’s omega, and the goodness of fit indexes used for the SEM models were the RMSEA, the CFI, the TLI and the GFI. The analysis was carried out using R software. (Results) The reliability of the scales in both models was adequate (w>0.70), although the metrics in the proposed model produced better results. The AFE suggested a different structure for the ECEAU, keeping some dimensions of the original structure and modifying and eliminating others. The goodness of fit indexes in both models were almost identical, with RMSEA=0.02, CFI=0.99, TLI=0.99 and GFI=0.98, which provides supporting evidence for the factorial structures proposed. (Conclusions) The original structure of the ECEAU was confirmed, while the differences in the results of the estimation and rotation methods generated another equally valid factorial structure for measuring the school climate construct in this university, and could be applied to other similar contexts.

Global databases such as Web of Science and Scopus have determined the standard indicators to measure the research output in national comparisons and its quality evaluation for decades. Already classic studies of science proved that this landscape of scientific production was distorted by using overly selective bibliographical indexes that were considered “international databases” while their coverage was severely limited. A relevant part of the bibliometric literature in the last 10 years has revolved around the limitations of these global data sources and the search for alternatives to explore more comprehensive universes of the scholarly output, considering all disciplines and languages. Particularly relevant in this debate are some recently created bibliographic services and search engines that provide new opportunities: Dimensions, Lens, Open Alex, CrossRef and Google Scholar. Our specific contribution to these studies relies on a methodological shift based on a convergence between prosopography and bibliometrics. For that end, we selected two countries that can be considered “peripheral centers” in the Latin American region. Firstly, we determined a universe of national researchers of the National Council for Scientific and Technological Development (CNPq, Brazil) and the National Council for Scientific and Technical Research (CONICET, Argentina). The target populations are composed of 10,619 tenured researchers at CONICET and 14,418 holders of the CNPq’s “research productivity fellowship”. Secondly, we built a database with their comprehensive publishing performance uploaded in the national curricular information systems, the Brazilian Lattes and Argentina’s SIGEVA, that includes metadata for all articles. After computational and manual data cleaning of this database, we retained a total 464,361 articles for Brazil and 81,005 for Argentina published in 2013-2020. The comparative study shows that Argentina and Brazil have similar patterns of coverage in the global databases, although they differ in terms of collaboration practices and national publishing.

SUMMARY: In the present study, it is aimed to reveal the performances of different classification algorithms in sex determination from first cervical vertebra, that is, atlas measurements. The classification success of 4 different machine learning algorithms was comparatively examined for the purpose of sex determination by evaluating 22 atlas measurements on cone beam computed tomography (CBCT) images of 145 female and 145 male adults. Logistic regression (LR), classification and regression tree (CART), support vector machine (SVM) and neural network (NN) algorithms were used for sex diagnosis. Area under the ROC curve (AUC), classification accuracy (CA), F1-ratio, Precision and Recall indexes were used for model performances. Except for 2 measurements, there was a significant difference between men and women in terms of 20 other parameters (p<0.05). The adjusted effects of these parameters on sex determination were examined with multivariate models and algorithms, and the success of all 4 algorithms was quite good. The success of the NN algorithm (Accuracy 91.3 %; 0.87 Specificity, 0.85 Sensitivity) in correctly classifying male and female was the highest, followed by the LR algorithm (Accuracy 90.9 %; 0.86 Specificity, 0.83 Sensitivity). It was found that the machine learning algorithm applied to the variables of the atlas gave high accuracy regarding sex and the NN model was highly effective in sex determination. In addition, a large morphometric database of atlas was presented in our results.

RESUMEN: El objetivo de estudio fue revelar el desempeño de diferentes algoritmos de clasificación en la determinación del sexo a partir de la primera vértebra cervical, el atlas. El éxito de la clasificación de 4 algoritmos diferentes de aprendizaje automático se examinó comparativamente con el fin de determinar el sexo mediante la evaluación de 22 mediciones de atlas en imágenes de tomografía computarizada de haz cónico (CBCT) de 145 mujeres y 145 hombres adultos. Para el diagnóstico de sexo se utilizaron algoritmos de clasificación y árbol de regresión (CART), máquina de vectores de soporte (SVM) y redes neuronales (NN). Para el rendimiento del modelo se utilizaron el área bajo la curva ROC (AUC), la precisión de clasificación (CA), la relación F1, los índices de precisión y recuperación. Excepto en dos mediciones, hubo una diferencia significativa entre hombres y mujeres en otros 20 parámetros (p<0,05). Los efectos ajustados de estos parámetros en la determinación del sexo se examinaron con modelos y algoritmos multivariados, y el éxito de los cuatro algoritmos fue bastante bueno. El éxito del algoritmo NN (Precisión 91,3 %; 0,87 Especificidad, 0,85 Sensibilidad) en clasificar correctamente a hombres y mujeres fue el más alto, seguido por el algoritmo LR (Precisión 90,9 %; 0,86 Especificidad, 0,83 Sensibilidad). Se encontró que el algoritmo de aprendizaje automático aplicado a las variables del atlas dio una alta precisión con respecto al sexo, y el modelo NN fue altamente efectivo en la determinación del sexo. Además, en nuestros resultados se presentó una importante base de datos morfométricos del atlas.

ABSTRACT. Body condition (BC) can affect the reproductive output and hatchling survival of nesting olive ridley turtles (Lepidochelys olivacea). However, little is known about the BC of nesting females during the arrival event at nesting sites. Therefore, this study aimed to evaluate the BC of females nesting in La Escobilla Beach Sanctuary (La Escobilla) during the 2021 nesting season. Nesting females were measured and weighed. The mean size for nesting L. olivacea was 60.41 ± 2.98 cm for straight carapace length, 52.69 ± 2.57 cm for straight carapace width, and 34.35 ± 3.94 kg for weight (n = 483). The mean (± standard deviation, SD) Fulton′s/Bjorndal BC index estimated for nesting females was 1.54 ± 0.15, while the mean (± SD) of body mass index was 2.18 ± 0.23. Based on these indexes, 28 individuals were classified as in bad condition, 315 in good condition, and 19 in excellent condition. This first estimation of the olive ridley turtle body condition in a nesting colony showed that BC is a good body condition for most nesting females in La Escobilla. This study is a valuable baseline for nesting L.olivacea's health condition.

Abstract Introduction : Older adults with advanced chronic diseases and palliative care needs are more exposed to polypharmacy and use of potentially inappropriate medication, which generates a high risk of adverse events and impaired quality of life. The objective of this study was to describe the frequency of potentially inappropriate medication use among older adults with palliative care needs receiving home care services after hospital discharge. Methods : Observational cross-sectional study of pharmacy dispensing and electronic health records, of older adults in a home care system and with palliative care needs according to the screening with the NECPAL tool or the PROFUND and/or PALIAR indexes. Dispensed medications during 180 days after admission to home care were analyzed. Medications were classified as po tentially inappropriate according to the LESS-CHRON criteria. Results : We included 176 patients, mean age 87.4 years, 67% were women; 73% were pluripathologic pa tients and 22% had one chronic progressive disease. Mortality at 6 months was 73%. Median frequency of dispensed medications per patient was 9.1 (IQR = 4-9.7). The frequency of potentially inappropriate medication dispensation among patients was 87%, mainly antihy pertensives, benzodiazepines and antipsychotics. Conclusion : This study observed that dispensation of potentially inappropriate medication among older adults with palliative care needs and home care services is very high. This emphasizes the need for effective patient-centered interventions to prevent inadequate prescription and stimulate de-prescription.

Resumen La estabilidad del color de la restauración temporal es muy importante, especialmente en zonas sensibles desde el punto de vista estético. En la presente investigación, el objetivo fue determinar el efecto del cemento temporal sobre el color de coronas temporales realizadas mediante métodos de prensado convencionales (indirectos) y tecnologías CAM/CAD utilizando fresadora e impresora 3D. Este estudio se llevó a cabo en un laboratorio y se utilizó color A2 en todos los métodos de fabricación. El color de las restauraciones se midió mediante un espectrofotómetro después de cementarlas con cemento de resina provisional. Luego se calcularon los cambios de color de las muestras (de 0 a 100) utilizando el sistema CIE Lab. El análisis de los datos se basó en métodos de estadística descriptiva y pruebas estadísticas, incluido el análisis de varianza unidireccional (ANOVA) y la prueba post hoc de Tukey. Según los resultados del análisis de varianza unidireccional, hubo una diferencia significativa entre los tres grupos en términos de los índices a y b (P<0,001), pero en términos del índice l, no hubo diferencias significativas entre los tres grupos (P=0,250). Además, según la prueba post hoc de Tukey, se observó una relación significativa entre el primer y el segundo grupo de impresoras 3D y entre el primer y el tercer grupo de fresado (P<0,001). Sin embargo, no se observó ninguna diferencia significativa en el grupo de prensado convencional. Los resultados mostraron que el mayor cambio de color entre los tres métodos fue con el método de impresión 3D, y la menor cantidad fue con el método de fresado.

Abstract The color stability of temporary restoration is crucial, especially in sensitive areas in terms of aesthetics. This research aimed to determine the effect of temporary cement on the color of temporary crowns made by conventional pressing methods (indirect) and CAM/CAD technologies using milling machines and 3D printers. This study was carried out in a laboratory, utilizing A2 color in all manufacturing methods. The color of the restorations was measured by a spectrophotometer after cementation with semi-permanent resin cement. Subsequently, color changes of the samples (ranging from 0 to 100) were calculated using the Commission International de l'Eclairage (CIE) Lab system. Data analysis was based on descriptive statistics methods and statistical tests, including one-way analysis of variance (ANOVA) and Tukey's post hoc test. According to the results of ANOVA, there was a significant difference between the three groups in terms of the 'a' and 'b' indexes (P<0.001). However, regarding the 'l' index, no significant difference was observed among the three groups (P=0.250). Also, based on Tukey's post hoc test, a significant relationship was seen between the first and second pairs in the 3D printer group, and between the first and third pairs in the milling group (P<0.001). However, no significant difference was observed in the conventional pressing group. The results showed that the 3D printing method exhibited the highest amount of color change among the three methods, while the milling method demonstrated the lowest amount of change.

Abstract Mexico has alarming suicide rates among adolescents and young people. Therefore the objective of the research was to explain how depression influences the manifestation of suicidal thoughts and attempts in young people and, in addition, to know if suicides in the country vary significantly according to their sex. The CHAID classification method, simple indexes, and mean difference were used to test these assumptions. The results for Sonora, Mexico show that there is a connection between depression and the manifestation of suicidal thoughts and attempts in adolescents (X2 Suicidal ideation >200, P-value < 0.01; X2 Suicidal attempt >77, P-value < 0.01). In addition, the number of youth suicides in the country from 1998 to 2021 on average is different between females and males (T-Student = 15.32, P-Value < 0.05; Mean number of suicides in males = 1150, Mean number of suicides in females = 357). We conclude a marked prevalence of depression in young people, is linked to the increase in suicides in Mexico, especially in women. This highlights the urgency of implementing gender-specific preventive strategies and promoting early awareness.

Resumen México tiene alarmantes tasas de suicidios de adolescentes y jóvenes. Por ello el objetivo de la investigación fue explicar cómo la depresión influye en la manifestación de pensamientos e intentos suicidas en jóvenes y, además, conocer si los suicidios en el país varían de manera significativa según el sexo de estos. Los métodos utilizados para probar dichos supuestos fueron el método de clasificación denominado CHAID, índices simples y diferencia de medias. Los resultados para Sonora, México demuestran que existe conexión entre depresión y la manifestación de pensamientos e intentos suicidas en adolescentes (X2 Ideación suicida >200, P-Valor < 0.01; X2 Intento suicida >77, P-Valor < 0.01). Además, el número de suicidios de jóvenes en el país, de 1998 a 2021, en promedio son diferentes entre la mujer y el hombre (T-Student = 15.32, P-Valor < 0.05; Media de suicidios en hombres = 1150, Media de suicidios en mujeres = 357). Se concluye una marcada prevalencia de depresión en jóvenes, vinculada al aumento de suicidios en México, especialmente en mujeres. Esto resalta la urgencia de implementar estrategias preventivas específicas por sexo y promover la concienciación temprana.

Abstract This article describes the experiences of managing scientific research processes, embodied in the specialization course in higher education management held in Angola, funded by the European Union in the 2022- 2023 biennium and supported by the Ministry of Higher Education, Science, Technology, and Innovation. During two editions of the course, aspects were identified that provided an understanding and explanation of the weaknesses, challenges and opportunities for improving the quality of higher education management, not only as a way to contribute to its strengthening, but also to highlight the relevance of the link between the dimensions of teaching, scientific research, university extension and their impact on increasing the scientific productivity of Angolan Higher Education Institutions (HEIs). This action allowed sharing epistemological, methodological, and technological approaches that enable monitoring the implementation of good practices in scientific research. The methodological approach used was mixed, given the need to compile, analyze and integrate quantitative and qualitative data. The study population consisted of 159 managers from public, public-private and private HEIs. The results show that there is a lack of funding, adequate infrastructure to carry out scientific research and development activities, differentiated human resources, as well as the need to create a public institution with the skills to process ISBN, ISSN and DOI in the country. It is concluded that the potentialities of the obtained results will have an impact on guiding public policies aimed at scientific and technological development. This insight comes from considering that, even after 62 years of institutionalization of higher education in Angola, internal scientific productivity has not yet reached significant levels in the global indexes of science, technology, and innovation.

Resumen Este artículo describe las experiencias de gestión de procesos de investigación científica plasmadas en el curso de especialización en gestión de la educación superior realizado en Angola, financiado por la Unión Europea, en el bienio 2022-2023, y apoyado por el Ministerio de Educación Superior, Ciencia, Tecnología e Innovación. Durante dos sesiones del curso se identificaron aspectos que permitieron comprender y explicar las debilidades, desafíos y oportunidades para mejorar la calidad de gestión de la educación superior no solo como una manera de contribuir con su fortalecimiento, sino también para enfatizar la relevancia del vínculo entre las dimensiones de la docencia, investigación científica, extensión universitaria y su impacto en el aumento de la productividad científica de las Instituciones de Educación Superior (IES) angolanas. Esta acción posibilitó compartir enfoques epistemológicos, metodológicos y tecnológicos que permiten monitorear la implementación de buenas prácticas de investigación científica. El abordaje metodológico utilizado fue mixto dada la necesidad de compilar, analizar e integrar datos cuantitativos y cualitativos. La población de estudio estuvo constituida por 159 gestores de IES públicas, público-privadas y privadas. Los resultados obtenidos indican insuficiencias de financiamiento, infraestructura adecuada para realizar actividades de investigación y desarrollo científico, recursos humanos diferenciados, así como la necesidad de crear una institución pública con competencias para procesar el ISBN, ISSN y DOI en el país. Se concluye que el potencial de los resultados obtenidos tendrá impacto en la orientación de las políticas públicas dirigidas al desarrollo científico y tecnológico. Este entendimiento ocurre al considerar que, incluso después de 62 años de institucionalización de la educación superior en Angola, la productividad científica interna aún no ha alcanzado niveles significativos en los índices globales de ciencia, tecnología e innovación.

Resumo Este artigo descreve as experiências de gestão de processos de investigação científica consubstanciadas no curso de especialização em gestão do ensino superior realizado em Angola, financiado pela União Europeia no biénio 2022-2023 e apoiado pelo Ministério do Ensino Superior, Ciência, Tecnologia e Inovação. Durante duas edições do curso, foram identificados aspetos que propiciaram a compreensão e explicação das fragilidades, desafios e oportunidades para aprimorar a qualidade de gestão do ensino superior, não só como uma maneira de contribuir para o seu fortalecimento, mas também para ressaltar a relevância do elo entre as dimensões ensino, investigação científica, extensão universitária e a sua incidência no aumento da produtividade científica das Instituições de Ensino Superior (IES) angolanas. Esta ação possibilitou partilhar abordagens epistemológicas, metodológicas e tecnológicas que permitem monitorar a implementação de boas práticas de investigação científica. O enfoque metodológico utilizado foi misto, atendendo à necessidade de compilar, analisar e integrar dados de natureza quantitativa e qualitativa. A população estudada consistiu em 159 gestores de IES públicas, público- privadas e privadas. Os resultados obtidos demonstram insuficiências de financiamento, de infraestruturas adequadas para realizar atividades de investigação científica e desenvolvimento, de recursos humanos diferenciados, bem como a necessidade de criação de uma instituição pública com competências para tramitar o ISBN, ISSN e o DOI no país. Conclui-se que as potencialidades dos resultados obtidos terão impacto na orientação de políticas públicas destinadas ao desenvolvimento científico e tecnológico. Este discernimento ocorre ao considerar que, mesmo após 62 anos de institucionalização do ensino superior em Angola, a produtividade científica interna ainda não alcançou níveis expressivos nos índices globais de ciência, tecnologia e inovação.

Abstract Introduction The lama-bordo systems (LBS) are built in natural watercourses and favor retention of sediment and runoff moisture for the development of agricultural activity. Objective To obtain a model for predicting the volume of soil permanently captured by LBS, based on the morphometric and hydrological characteristics of the micro-watersheds where they have prevailed in the Mixteca Alta of Oaxaca, Mexico Materials and methods The study was carried out in 27 sites where morphometric parameters and hydrological indexes were determined to obtain the volume prediction model by multiple linear regression (backward elimination technique). Results and discussion The systems studied were found in micro-watersheds under conditions that favor sediment transport: elongated shape, areas smaller than 2 km2 with 1st and 2nd order streams, at altitudes above 2 000 m and slopes greater than 10 %. Twelve morphometric parameters and three hydrological indexes characterize these micro-watersheds and explain the physical conditions that allow their establishment, but only four (micro-watershed area, average slope of the mainstream, topographic wetness index and sediment transport index) explain the cumulative sediment volume (R2 = 0.85, P < 0.001). Conclusions The model evaluated for volume estimation is reliable for application at sites under similar conditions.

Resumen Introducción Los sistemas lama-bordo (SLB) se construyen en cauces naturales y favorecen la retención de sedimentos y humedad del escurrimiento para el desarrollo de la actividad agrícola. Objetivo Obtener un modelo de predicción de volumen de suelo captado por los SLB en forma permanente, a partir de las características morfométricas e hidrológicas de las microcuencas donde estos han prevalecido en la Mixteca Alta de Oaxaca, México. Materiales y métodos El estudio se hizo en 27 sitios donde se determinaron parámetros morfométricos e índices hidrológicos que permitieron obtener el modelo de predicción de volumen mediante regresión lineal múltiple tipo backward stepwise. Resultados y discusión Los sistemas estudiados se encontraron en microcuencas bajo condiciones que favorecen el transporte de sedimentos: forma alargada, áreas menores de 2 km2 con corrientes de 1° y 2° orden, en altitudes superiores a los 2 000 m y pendientes mayores de 10 %. Doce parámetros morfométricos y tres índices hidrológicos caracterizan dichas microcuencas y explican las condiciones físicas que permiten su establecimiento, pero solo cuatro (área de la microcuenca, pendiente media de la corriente principal, índice topográfico de humedad e índice de transporte de sedimentos) explican el volumen de sedimento acumulado (R2 = 0.85, P < 0.001). Conclusiones El modelo evaluado para la estimación de volumen es confiable para su aplicación en sitios bajo condiciones similares.

Abstract Invisible illnesses, which are not outwardly visible, encompass mental, cognitive, and physical conditions that impair daily activities. Promoting self-management for patients living with these chronic conditions has been the central aim of healthcare systems around the world. Through an analysis of medical consultations with student patients at a university healthcare facility in Chile, we propose a framework that identifies the themes, sub-themes, and indexes that embody the identity work of expert patients with invisible chronic health conditions. The study explores the complexity of the resources and doctor-patient alignments used to perform patient expertise in natural interactions and the key role of experiential knowledge in the self-diagnosis and the management of invisible illnesses.

Resumen Las discapacidades invisibles, que no son evidentes a simple vista, abarcan condiciones mentales, cognitivas y físicas que dificultan las actividades diarias. Promover la autogestión de estas enfermedades crónicas ha sido el objetivo central de los sistemas sanitarios de todo el mundo. Analizando las consultas médicas con estudiantes que son pacientes en un centro de salud universitario en Chile, proponemos un marco que identifica los temas, subtemas e índices que encarnan el trabajo identitario de pacientes expertos con enfermedades crónicas invisibles. El artículo explora la complejidad de los recursos y las alineaciones médico-paciente que se utilizan para construir la experiencia del paciente en interacciones naturales y el papel central del conocimiento experiencial en el autodiagnóstico y el manejo de enfermedades invisibles.

ABSTRACT Taurine supplementation has shown survival and feeding efficiency in larval fish development. Thus, the present study aims to evaluate the effects of adding taurine to the longfin yellowtail (Seriola rivoliana) diet for 60 days. Fish (n = 270) were distributed in three treatments: T0 without taurine, T1, and T2, supplemented with taurine at 1 and 2%, respectively. Growth performance, blood serum biochemistry, fatty acid, and amino acid profiles in skeletal muscle were evaluated. Notable improvements (P < 0.05) were observed in T1 and T2 in terms of specific growth rate (SGR) and weight gain (WG). Survival rates (SR) did not show significant differences (P > 0.05). In addition, a decrease was observed in intraperitoneal fat (IPF). Still, an increase was observed in blood parameters, including higher total protein (TP) and globulin (GLO) concentration, as well as a reduction in cholesterol (CHO) levels. Changes in fatty acid profiles were also detected in skeletal muscle with an increase in omega-3 fatty acids (EPA and DHA) and elevation in taurine concentration in T2. The results showed that adding 20 g kg-1 of taurine to the diet improved growth, skeletal muscle, and blood serum biochemistry. Therefore, the use of higher taurine concentrations is recommended in future studies to understand fully the extent of the benefits to longfin yellowtail juveniles.

Abstract (Introduction): The variability of geographic space, in terms of the horizontal structure of landscapes, influences ecology and suggests an association between landscape heterogeneity indices (LHI) and ecosystem services (ES). This relationship is crucial for conservation and sustainable development in Latin America, given the diversity of landscapes, from tropical forests to snow-capped mountains and deserts, which harbor a unique wealth of biodiversity and ecological functions. The objective of this study was to determine the relationship between LHI and ES. (Methodology): Fourteen landscape heterogeneity indices and seven ecosystem services were calculated in Santa María Huatulco, Oaxaca, and related to the estimated ecosystem services for the same area. (Results): The models showed a statistically significant relationship between LHI and ES, suggesting that certain LHI can influence the provision and distribution of ES. (Conclusions): Therefore, understanding how LHI affect ES is essential to promote sustainable development in Latin America.

Resumen (Introducción): La variabilidad del espacio geográfico, en términos de la estructura horizontal de los paisajes, influye en la ecología y sugiere una asociación entre los índices de heterogeneidad paisajística (IHP) y los servicios ecosistémicos (SE). Esta relación es crucial para la conservación y el desarrollo sostenible en América Latina, dada la diversidad de paisajes, desde selvas tropicales hasta montañas nevadas y desiertos, que albergan una riqueza única de biodiversidad y funciones ecológicas. (Objetivo): Se buscó determinar la relación entre los IHP y los SE. (Metodología): Se calcularon catorce índices de heterogeneidad paisajística y siete servicios ecosistémicos en el municipio de Santa María Huatulco, Oaxaca, y se relacionaron con los servicios ecosistémicos estimados para la misma área de estudio. (Resultados): Los modelos demostraron una relación estadísticamente significativa entre los IHP y los SE. (Conclusiones): Investigar y comprender como los IHP afectan la oferta y distribución de los SE es esencial para promover un desarrollo sostenible en América Latina.
