ABSTRACT Andean and Bolivian Indigenous Communities of Titicaca often depend on their natural resources to ensure their food security, making them especially vulnerable to environmental fluctuations and changes in the ecosystem. Under this criterion, this study applies a qualitative methodology to analyze the relationship between the food security of the communities of the Cohana Bay region (taking the Chojasivi community as a case study) and water pollution in the Katari basin. The results reveal that such contamination has generated a potential effect on access, availability, use and stability over time of the food that makes up the basic food basket of the community.

RESUMEN Las comunidades Indígenas Andino-bolivianas del Titicaca dependen a menudo de sus recursos naturales para garantizar su seguridad alimentaria, lo que las hace especialmente vulnerables a fluctuaciones ambientales y cambios en el ecosistema. Bajo ese criterio, el presente estudio aplica una metodología cualitativa para analizar la relación existente entre la seguridad alimentaria de las comunidades de la región de la bahía de Cohana (tomando como caso de estudio a la comunidad de Chojasivi) y la contaminación hídrica presente en la cuenca Katari. Los resultados revelan que dicha contaminación ha generado un efecto potencial en el acceso, disponibilidad, uso y estabilidad en el tiempo de los alimentos que componen la canasta básica de los comunarios.

ABSTRACT Food availability is defined as the sufficient quantity of food of adequate quality and culturally acceptable for the population of a country in a given period. In the case of the cities of the North Coast of the Uruguay River, there is little availability in terms of local fishing. The objectives of this research were to analyze the causes of this scarce availability through the opinion of the artisanal fishermen of the region, and the referring institutions. Semi-structured interviews were conducted with artisanal fishermen and institutional references in the region, as well as a representative of the private sector. The inability of fishermen to dedicate themselves exclusively to the activity; the export destination that has the majority of the region's catches; the low consumption at national level and the scarce demand of the cities for river fish, were some of the enunciated causes.

RESUMEN La disponibilidad de alimentos se define como la cantidad suficiente de alimentos de calidad adecuada y culturalmente aceptables para la población de un país en un período determinado. En el caso de las ciudades del Litoral Norte del Río Uruguay, se observa una escasa disponibilidad en materia de pesca local. Los objetivos de esta investigación fueron analizar las causas de esta escasa disponibilidad a través de la opinión de los y las pescadores artesanales de la región, y las instituciones referentes. Se realizaron entrevistas semi estructuradas a pescadores artesanales y referentes institucionales de la región, así como a un representante del sector privado. La imposibilidad de los pescadores para dedicarse exclusivamente a la actividad; el destino exportador que tiene la mayoría de las capturas de la región; el bajo consumo a nivel nacional y la escasa demanda de las ciudades por pescado de río, fueron algunas de las causas enunciadas.

RESUMEN Introducción: Estudios previos han reportado que pacientes infectados con el virus del COVID-19, podrían manifestar sintomatologías a nivel de la cavidad oral. Objetivo: Evaluar la frecuencia de manifestaciones orales asociadas a COVID-19 en un segmento de la población paraguaya y determinar cuáles son las más prevalentes. Metodología: Estudio descriptivo de corte transversal. Fue realizada una encuesta electrónica de enero a marzo del 2022. Los datos fueron presentados como frecuencias y porcentajes y analizados mediante la prueba de chi-cuadrado. El análisis estadístico se realizó con el software R versión 4.0.3. Resultados: La muestra estuvo compuesta por 478 personas. El 79,50 % correspondió al sexo femenino y el 45,19 % tenía entre 25 y 34 años. El 65,48 % informó haber experimentado al menos 1 síntoma o signo oral durante el curso de COVID-19. La pérdida de la sensación de sabores amargos, seguida de la alteración del sabor de los alimentos y la pérdida de la percepción dulce, fueron los síntomas más comunes. Se encontró una proporción significativamente mayor de manifestaciones orales en el rango de 18-24 años (χ²; p= 0,003). Entre las personas que desarrollaron COVID-19 de forma moderada a severa hubo mayor número de manifestaciones de síntomas orales (χ²; p= 0,044). Discusión: Se identificó una alta frecuencia de manifestaciones orales en pacientes con casos de moderados a severos de COVID-19, destacándose los trastornos del gusto como los más predominantes. Los individuos más jóvenes fueron los más afectados.

ABSTRACT Introduction: Previous studies have reported that patients infected with the COVID-19 virus could manifest symptoms in the oral cavity. Objective: To evaluate the frequency of oral manifestations associated with COVID-19 in a segment of the Paraguayan population and determine the most prevalent ones. Methods: Descriptive cross-sectional study. An electronic survey was conducted from January to March 2022. The data were presented as frequencies and percentages and analyzed using the chi-square test. Statistical analysis was performed with R software version 4.0.3. Results: The sample consisted of 478 individuals. 79.50% were female, and 45.19% were between 25 and 34 years old. 65.48% reported having experienced at least 1 oral symptom or sign during the course of COVID-19. The loss of the sensation of bitter tastes, followed by the alteration of the taste of foods and the loss of sweetness perception, were the most common symptoms. A significantly higher proportion of oral manifestations was found in the 18-24 age range (χ²; p= 0.003). Among people who developed COVID-19 in a moderate to severe form, a greater number of oral symptom manifestations were observed (χ²; p= 0.044). Discussion: A high frequency of oral manifestations was identified in patients with moderate to severe cases of COVID-19, with taste disorders standing out as the most predominant. Younger individuals were the most affected.

Abstract Background: Based on the concept of “plant species complex,”, defined as a group sharing local names and morphological, aromatic, and curative properties, we analyzed the leaves of three species of the genus Oreopanax that are used as wrappers for tamales called “xocos” or “chocos” in Veracruz, Mexico, searching for common traits. Question: Do leaves of the genus Oreopanax form an ethnobotanical food complex sharing chemical and anatomical characteristics? Studied species / data description: Leaves from three species of the genus Oreopanax: O. capitatus, O. echinops, and O. flaccidus. Study site and dates: Leaves of O. capitatus and O. echinops were recollected on January 25 and 26, 2021, in the Clavijero Botanic Garden of the Instituto de Ecología, A. C. in Xalapa, Veracruz; leaves of O. flaccidus were recollected in Atapalchico, Tlacolulan, Veracruz. Methods: Chemical analyses consisted of oil extraction of the studied species' leaves, which were then injected into a gas chromatographer coupled to a mass spectrometer (GC-MS). Anatomical analyses included: fixation, paraffin sectioning, and staining of leaf sections of the three species. Observations were performed with a compound microscope using a bright field or UV light. Results: For the first time, we are reporting major volatile compounds common in the three analyzed species (several aliphatic and aromatic alcohols, and terpenoids). The three species present resin canals in the mesophyll and the cortex of the midrib of the leaf. Conclusions: The studied Oreopanax species form an ethnobotanical food complex since they share similar uses, smells, and tastes.

Las especies presentan canales resiníferos en el mesófilo y en el córtex de la vena media de la hoja . Conclusiones: Las especies de Oreopanax estudiadas forman un complejo etnobotánico alimenticio, pues comparten usos, olores y sabores similares.

Food and Nutrition Security (SAN) is the realization of everyone's right to access food in sufficient quantities, quality and regularly, without compromising access to other needs. In view of the increase in food and nutrition insecurity, observed in recent years in Brazil and in the world, concomitant with the disruption of programs and public policies combined with the incentive to promote the right to Food and Nutritional Security (SAN) in Brazil (2019-2022) , and the pandemic context that aggravated this problem, we are currently experiencing alarming levels of Food and Nutrition Insecurity (INSAN), including the serious one that is characterized by hunger, which preferentially affects a certain social class and region in Brazil, North and Northeast. The present study analyzed the food and nutritional security profile of families residing in the rural community of Sítio Laguinha, around a wind farm in the municipality of Caetés, in Pernambuco. This study can be characterized as a mixed descriptive study with a quantitative and qualitative approach, in order to identify the prevalence of food (in)security and the associated factors. A semi-structured questionnaire was used to obtain information on socioeconomic conditions and food consumption in the rural community of Laguinha, as well as the Brazilian Food Insecurity Scale (EBIA) to assess the situation of Food and Nutritional Security. Among the factors associated with the community, the vulnerabilities to which this community is exposed stand out, such as the location in a rural area that is difficult to move around, around a wind farm that brings with it impacts and the pandemic context. The results obtained showed a high prevalence of food and nutritional insecurity (88.4%) at all levels, mild, moderate and severe. Among the factors that may be associated with and aggravate the INSAN situation, we can mention the impact of the wind farm and the pandemic, with all associated socioeconomic impacts. The results obtained in this work bring relevant data about the situation of an invisible community that needs assistance to achieve food and nutritional security, a right established in our constitution. In addition, these data can serve as a basis for the implementation of public policies aimed at the community

A Segurança Alimentar e Nutricional (SAN) é a realização do direito de todos ao acesso a alimentos em quantidade suficiente, qualidade e regularmente, sem comprometer o acesso a outras necessidades. Diante do aumento da insegurança alimentar e nutricional, observada nos últimos anos no Brasil e no mundo, concomitante com a desestruturação de programas e políticas públicas aliadas ao incentivo à promoção do direito à Segurança Alimentar e Nutricional (SAN) no Brasil (2019-2022), e o contexto pandêmico que agravou esse problema, atualmente vivenciamos índices alarmantes de Insegurança Alimentar e Nutricional (INSAN), incluindo a insegurança grave que se caracteriza pela fome, que afeta preferencialmente uma determinada classe social e região no Brasil, Norte e Nordeste. O presente estudo analisou o perfil da segurança alimentar e nutricional de famílias residentes na comunidade rural do Sítio Laguinha, em torno de um parque eólico no município de Caetés, em Pernambuco. Esse estudo pode ser caracterizado como descritivo misto com abordagem quantitativa e qualitativa, a fim de identificar a prevalência da (in)segurança alimentar e os fatores que a ela se associam. Foram utilizados um questionário semiestruturado para obtenção de informações sobre condições socioeconômicas e de consumo alimentar da comunidade rural de Laguinha bem como a Escala Brasileira de Insegurança Alimentar (EBIA) para avaliar a situação de Segurança Alimentar e Nutricional. Dentre os fatores associados à comunidade destaca-se as vulnerabilidades às quais essa comunidade está exposta, como a localização em uma área rural de difícil deslocamento, em torno de um parque eólico que traz consigo impactos e o contexto pandêmico. Os resultados obtidos mostraram alta prevalência de insegurança alimentar e nutricional (88,4%) em todos os níveis, leve, moderada e grave. Dentre os fatores que podem estar associados e agravar a situação de INSAN podemos citar o impacto do parque eólico e a pandemia, com todos impactos socioeconômicos associados. Os resultados obtidos neste trabalho trazem dados relevantes sobre a situação de uma comunidade invisibilizada e que necessita de assistência para alcançar a segurança alimentar e nutricional, um direito estabelecido na nossa constituição. Além disso, esses dados podem servir de base para implementação de políticas públicas voltadas à comunidade.

ABSTRACT The symbiosis of common beans with nitrogen-fixing bacteria provides an efficient approach to sustainable and economical food production. Therefore, this study aimed to evaluate the application of cost-effective nitrogen management strategies in organic common bean cultivation, including the application of poultry manure and organic liquid fertilizer, seed and co-inoculation with diazotrophic bacteria (Azospirillum brasilense and/or Rhizobium tropici), and supplementary Rhizobium tropici inoculation. The study spanned three years in a well-established organic cultivation field (2018) and an initial organic cultivation area (2019 and 2020) in Brazil. It was arranged in a randomized blocks design in a 2 × 5 (2018) and 2 × 6 (2019 and 2020) factorial scheme, with four replicates. The most profitable strategy involves seed inoculation with Azospirillum brasilense and additional inoculation with Rhizobium tropici at stage V4-5 (fifth trifoliate leaf fully expanded), while the most costly strategy was the application of poultry manure at the V3 stage (first trifoliate leaf fully expanded). Thus, the use of diazotrophic bacteria for seed inoculation and co-inoculation (Azospirillum brasilense and/or Rhizobium tropici) ensured financial returns and system profitability in common bean cultivation.

RESUMO A simbiose do feijão comum com bactérias fixadoras de nitrogênio proporciona uma abordagem eficiente para a produção de alimentos sustentável e econômica. Portanto, este estudo teve como objetivo avaliar a aplicação de estratégias custo-efetivas de manejo de nitrogênio no cultivo orgânico do feijão comum, incluindo a aplicação de esterco de aves e fertilizante orgânico líquido, inoculação de sementes e coinoculação com bactérias diazotróficas (Azospirillum brasilense e/ou Rhizobium tropici), e inoculação suplementar com Rhizobium tropici. O estudo durou três anos em um campo de cultivo orgânico bem estabelecido (2018) e uma área inicial de cultivo orgânico (2019 e 2020) no Brasil. O delineamento foi em blocos casualizados em esquema fatorial 2 × 5 (2018) e 2 × 6 (2019 e 2020), com quatro repetições. A estratégia mais lucrativa envolve a inoculação de sementes com Azospirillum brasilense e inoculação adicional com Rhizobium tropici no estádio V4-5 (quinta folha trifoliada totalmente expandida), enquanto a estratégia mais cara foi a aplicação de esterco de aves no estádio V3 (primeira folha trifoliada totalmente expandida). Assim, o uso de bactérias diazotróficas para inoculação e coinoculação de sementes (Azospirillum brasilense e/ou Rhizobium tropici) garantiu retorno financeiro e rentabilidade do sistema no cultivo do feijão comum.

Abstract Literature has emphasized on food environments centrality in food choices and nutritional status. Objective: identify social perceptions of fathers, mothers and guardians, professionals from educational establishments, municipal officials, and stallholders belonging to the southern area of Santiago de Chile, regarding limitations of healthy diet implementation on school environments. Method: six focus groups were carried out grouping 50 key actors linked to educational establishments using a non-probabilistic sample. A content analysis was applied through thematic coding technique seeking to reveal emerging semantic universes. Results: Nine barriers, or semantics, were identified characterizing limitations to healthy eating habits in school environments: family, school kiosks, leaving school establishments, taste, socioeconomic determinants, public policy, lack of knowledge, publicity, and availability of products without seals. Conclusions: limitations associated with domestic food environment have a significantly high representation (47,9%) and contain an individualized responsibility feature. This explanatory culture is opposed to scientific and academic evidence regarding the functioning of eating behavior, and the centrality of food environments facilitating or hindering healthy food consumption.

Resumen La literatura ha hecho hincapié en la centralidad que cumplen los entornos alimentarios en las elecciones alimentarias y en el estado nutricional de la población. Objetivo: identificar las percepciones de padres, madres y apoderados, profesionales de establecimientos educacionales, funcionarios municipales, y feriantes pertenecientes a la zona sur de Santiago de Chile, respecto a las barreras y limitaciones de la puesta en práctica de una alimentación saludable en el ambiente alimentario escolar. Método: se realizaron seis grupos focales agrupando a 50 actores claves vinculados a los establecimientos educacionales de Ciudad Sur utilizando una muestra no probabilística. Se aplicó un análisis de contenido mediante la técnica de codificación temática buscando relevar los universos semánticos emergentes. Resultados: se identificaron nueve barreras, o semánticas, que caracterizan limitantes a la realización de la alimentación saludable en los entornos escolares desde la perspectiva de los participantes: la familia, kioscos escolares, la salida de los establecimientos escolares, gusto, determinantes socioeconómicos, política pública, falta de conocimiento, publicidad y disponibilidad de productos sin sellos. Conclusiones: las limitaciones asociadas al ambiente alimentario doméstico tienen una representación significativamente alta (47,9%) y contienen un carácter de responsabilización individual en su enunciación. Esta cultura explicativa es opuesta a la evidencia científica y académica respecto al funcionamiento de la conducta alimentaria, y a la centralidad de los ambientes alimentarios respecto a la facilitación u obstaculización del consumo de alimentos saludables o adecuados.

Abstract Systemic Arterial Hypertension is a multifactorial clinical condition associated with severe outcomes such as stroke and death. One of the main modifiable risk factor for hypertension is an unhealthy diet, often characterized by the consumption of ultraprocessed foods such as sweetened beverages. We aimed to investigate the relationship between the consumption of sweetened beverages, both sugar-sweetened and artificially sweetened, and the prevalence of hypertension in adults. A cross-sectional, household, population-based study with 1,162 adults from two Brazilian cities were carried out. The consumption of food groups and sweetened beverages was obtained by food frequency questionnaire and other data were self-reported. Weight, height, and waist circumference were measured. The association between sweetened beverages consumption and hypertension was analyzed using Poisson regression models, expressed as Prevalence Ratio. The prevalence of hypertension was 16.7%, with no significant difference between genders. The prevalence of consumption of sweetened beverages was 70.3% in men and 54.6% in women, being significantly higher in men. Women who consumed sugar-sweetened and artificially sweetened beverages 6 to 7 days per week had 92% higher prevalence of hypertension compared to those who did not consume or consumed at a lower frequency. Furthermore, women who consumed artificially sweetened beverages at least 1 time per week had 3.36 times higher prevalence of hypertension. The habitual consumption of sweetened beverages may be an important risk factor for hypertension, especially the consumption of diet beverages, which are often marketed as healthier than sugar-sweetened beverages.

Resumen La Hipertensión Arterial Sistémica es una condición clínica multifactorial asociada a resultados graves como el ictus y la muerte. Uno de los principales factores de riesgo modificables de la hipertensión es una dieta poco saludable, a menudo caracterizada por el consumo de alimentos ultraprocesados como las bebidas endulzadas. Nuestro objetivo fue investigar la relación entre el consumo de bebidas endulzadas, tanto azucaradas como edulcoradas artificialmente, y la prevalencia de hipertensión en adultos. Se realizó un estudio transversal, domiciliario y poblacional con 1,162 adultos de dos ciudades brasileñas. El consumo de grupos de alimentos y bebidas endulzadas se obtuvo mediante cuestionario de frecuencia de alimentos y los demás datos fueron autoinformados. Se midieron el peso, la talla y el perímetro de la cintura. La asociación entre el consumo de bebidas endulzadas y la hipertensión se analizó mediante modelos de regresión de Poisson, expresados como Ratio de Prevalencia. La prevalencia de hipertensión fue del 16,7%, sin diferencias significativas entre géneros. La prevalencia de consumo de bebidas endulzadas fue del 70,3% en los hombres y del 54,6% en las mujeres, siendo significativamente mayor en los hombres. Las mujeres que consumían bebidas azucaradas y edulcoradas artificialmente entre 6 y 7 días a la semana tenían 92% mayor prevalencia de hipertensión que las que no consumían o consumían con una frecuencia menor. Además, las mujeres que consumían bebidas edulcoradas al menos 1 vez por semana tenían una prevalencia de hipertensión 3,36 veces mayor. Así pues, el consumo habitual de bebidas endulzadas puede ser un importante factor de riesgo de hipertensión, especialmente el consumo de bebidas dietéticas, que a menudo se comercializan como más saludables que las bebidas azucaradas.

Abstract Nowadays, obesity has become one of the biggest public health challenges worldwide. This scenario includes Colombia as well. Against this background, the university environment constitutes a key scenario for addressing this situation. Research Objective: To characterize the food environment of a university in Medellín, Colombia. Materials and methods: A cross-sectional descriptive study was carried out through direct observation. Additionally, it was used structured forms for recording the data of the food establishments. The research considers the following variables: food supply, prices, advertising, facilitators and barriers. Results: No establishment was classified as healthy. In 76% of the establishments, the food-sets or promotions were cheaper. In 62% of the places under inspection, the healthy dishes were more expensive. Only in two establishments there was direct advertising that promoted healthy eating. In general, mainly ultra-processed edible products (53%) were offered. Conclusion: The results of the study generally paint a picture of an unhealthy food environment. This diagnosis is configured as an important input for decision-making within the institution to improve and promote a healthier diet that reduces the risk of developing chronic diseases in the university community.

Resumen La obesidad se ha convertido en una de las mayores problemáticas de salud pública a nivel mundial, y Colombia no es ajena a esta situación. El entorno universitario constituye un escenario clave para el abordaje de esta problemática. Objetivo: Caracterizar el entorno alimentario de una universidad en Medellín, Colombia. Materiales y métodos: Se realizó un estudio descriptivo transversal mediante la observación directa y registro en formularios estructurados de todos los establecimientos de venta de alimentos. Se consideraron las siguientes variables: oferta de alimentos, precio, publicidad, facilitadores y barreras. Resultados: Ningún establecimiento se clasificó como saludable. En el 76% de los establecimientos, los paquetes o promociones eran más económicos. En el 62% de los establecimientos se observó que los platos saludables eran más costosos. Solo en dos establecimientos se observó publicidad directa para fomentar una alimentación saludable. Se ofrecían principalmente productos ultraprocesados (53%). Conclusión: los resultados del estudio muestran en general un panorama de un entorno alimentario poco saludable. Este diagnóstico se configura como un insumo importante para la toma de decisiones al interior de la institución para mejorar y promover una alimentación más saludable que permita disminuir el riesgo de desarrollar enfermedades crónicas en la comunidad universitaria.

Abstract The aim of this study was to characterize in the retail outlets the marketing strategies used in food and non-alcoholic beverages aimed at children, adolescents, and their parents or guardians (shoppers) which influence the purchase of products of high energy content and low nutritional value in Costa Rica. Data collection was carried out in 2018 with an observation guide applied at the retail outlets (RO) (n: 12) and a questionnaire aimed at parents or guardians (shoppers) (n: 72) of the child and adolescent population. The study found that the marketing strategy most frequently used in the entry, cash and exit area the retail outlets was price reduction (79,0, 87.5 and 88,0%, respectively).There is a frequent and varied use of marketing strategies in retail outlets for calorie-dense food products with an excess of critical nutrients that are relevant in public health due to their association with obesity and non-communicable diseases.

Resumen El objetivo del presente estudio fue caracterizar en los puntos de venta de Costa Rica las estrategias de mercadeo utilizadas en alimentos y bebidas no alcohólicas dirigidas a la población infantil, adolescente y a sus padres o tutores (compradores), que influyen en la compra de productos de alto contenido energético y bajo valor nutricional. La recolección de datos se realizó en el 2018 mediante una guía de observación aplicada al punto de venta (n:12) y un cuestionario dirigido a los padres o tutores (n: 72) de la población infantil y adolescente. Se encontró que la estrategia de mercadeo utilizada con mayor frecuencia en el área de entrada, caja y salida del punto de venta fue la reducción de precios (79,0; 87,5 y 88,0%, respectivamente). En los puntos de venta existe un empleo frecuente y variado de estrategias de mercadeo de productos alimenticios densamente calóricos y con un exceso de nutrientes críticos que son relevantes en salud pública por su asociación con la obesidad y enfermedades no transmisibles.

Abstract Whole grains are a fundamental food category for the human diet and represent an invaluable source of carbohydrates, proteins, fibers, phytochemicals, minerals and vitamins. Many studies have shown that consumption of whole grains is linked to a lower risk of chronic non-communicable diseases. However, several of its positive health effects seem to disappear when grains are refined. The research question is what would be the effect of whole grains in the prevention of Chronic Non-Communicable Diseases. This article describes the positive effects of whole grain consumption in these diseases.To this end, a narrative description is made that reviews the available background on: a) epidemiological situation in Chile and its relationship with diet; b) consumption of whole grains in the world and in Chile; and c) the effect of whole grain consumption on reducing the risk of cardiovascular disease. obesity, type 2 diabetes, and cancer. The general background is very encouraging for a positive effect of whole grain consumption on certain diseases, especially those of metabolic origin. However, the uncertainty of some negative associations deserves further attention.

Resumen Los cereales integrales son una categoría de alimentos fundamental para la dieta humana y representan una fuente invaluable de carbohidratos, proteínas, fibras, fitoquímicos, minerales y vitaminas. Muchos estudios han demostrado que el consumo de cereales integrales está relacionado con un menor riesgo de enfermedades crónicas no transmisibles. Sin embargo, varios de sus efectos positivos para la salud parecen desaparecer cuando se refinan los cereales. La pregunta de investigación es cuál sería el efecto de los cereales integrales en la prevención de enfermedades crónicas no transmisibles. Este artículo describe los efectos positivos del consumo de cereales integrales en la prevención de estas enfermedades. Para ello, se realiza una descripción narrativa que revisa los antecedentes disponibles sobre: a) situación epidemiológica en Chile y su relación con la alimentación; b) consumo de cereales integrales en el mundo y en Chile; y c) el efecto del consumo de cereales integrales en la reducción del riesgo de enfermedad cardiovascular. obesidad, diabetes tipo 2 y cáncer. Los antecedentes generales son muy alentadores sobre el efecto positivo del consumo de cereales integrales sobre determinadas enfermedades, especialmente las de origen metabólico. Sin embargo, la incertidumbre de algunas asociaciones negativas merece mayor atención.

Resumo O presente estudo teve como objetivo determinar o efeito de diferentes níveis de proteína sobre o crescimento, composição corporal, perfil de aminoácidos e sorologia de alevinos de Channa marulius. O experimento foi conduzido em dez happas instalados em tanques de terra, cada um abastecido com 10 peixes, por 90 dias. Quatro alimentos para peixes comerciais com níveis de 25%, 30%, 32% e 40% de proteína bruta (PB) foram dados aos peixes com 3% de seu peso corporal úmido três vezes ao dia. Os resultados do estudo revelaram que maior ganho de peso, taxa de conversão alimentar e taxa de sobrevivência foram observados em 30% de proteína alimentar. Enquanto isso, o conteúdo de umidade foi maior em peixes alimentados com 30% de PB, enquanto a proteína bruta mais alta foi registrada em peixes alimentados com 40% de PB. O menor conteúdo de gordura foi observado em rações com 32% de PB. O perfil de aminoácidos dos peixes revelou melhores resultados na ração com 30% de PB. Proteína total, glicose e globulina também foram maiores em peixes alimentados com ração com 30% de PB, enquanto a albumina foi mais alta com 40% de PB. Conclui-se que a ração com 30% de PB apresentou melhores resultados em termos de crescimento, perfil de aminoácidos e parâmetros sorológicos sem afetar a composição corporal dos peixes.

Abstract The present study aimed to determine the effect of different levels of protein on the growth, body composition, amino acid profile and serology of Channa marulius fingerlings. The experiment was conducted in ten happas installed in earthen ponds, each stocked with 10 fishes for 90 days. Four commercial fish feeds having 25%, 30%, 32% and 40% crude protein (CP) levels were fed to fish at 3% of their wet body weight three times a day. The results of the study revealed that highest weight gain, feed conversion ratio and survival rate were observed in 30% protein feed. Meanwhile, moisture content was higher in fish fed with 30% CP feed while highest crude protein was recorded in 40% CP fed fish. Lowest fat content was observed in 32% CP feed. Amino acid profile of fish revealed better results in 30% CP feed. Total protein, glucose and globulin were also highest in fish feeding 30% CP feed, while albumin was highest in 40% CP feed. It is concluded that 30% CP feed showed better results in terms of growth, amino acid profile and serological parameters without effecting fish body composition.

Resumo Anfisbênas são répteis fossoriais caracterizadas por apresentarem corpo cilíndrico e alongado coberto por escamas dispostas exclusivamente em anéis e todas são ápodas, com exceção das três espécies do gênero Bipes. Sua dieta consiste em uma variedade de invertebrados e pequenos vertebrados. Por viverem no subsolo, muitos aspectos de sua história natural são difíceis de observar. A maioria dos estudos sobre alimentação em anfisbenas concentra-se na dieta e na ecologia alimentar, enquanto as informações sobre o comportamento alimentar se baseiam em observações preliminares. O objetivo deste artigo foi descrever o comportamento de captura de alimentos exibido por Leposternon microcephalum Wagler, 1824, fora da galeria, em cativeiro. Para o experimento foi utilizada uma isca não viva, ração úmida de gato, que foi oferecida e posicionada próxima a uma das aberturas da galeria, na superfície do solo. Um total de três animais foi analisadopor meio de observações visuais e registros de câmeras de telefones celulares posicionadas em um ponto fixo, captando imagens de suas vistas dorsal e lateral. Foram detectados dois tipos principais de comportamento: captura de recursos alimentares e mecanismo de defesa. As estratégias utilizadas para capturar o recurso alimentar foram semelhantes às observadas em outras espécies fossoriais. Embora o movimento de “marcha-à-ré” tenha sido observado e descrito, o registramos sendo usado como uma estratégia de fuga. Esses resultados contribuem para enriquecer o conhecimento sobre diferentes aspectos da história natural dos Amphisbaenia.

Abstract Amphisbaenians are fossorial reptiles that have a cylindrical and elongated body covered with scales arranged in rings, and are all apodal, except for the three species of the genus Bipes. The amphisbaenian diet consists of a variety of invertebrates and small vertebrates. As these animals live underground, many aspects of their natural history are difficult to study. Most feeding studies of amphisbaenians have focused on the composition of the diet and feeding ecology, and the data available on feeding behavior are based on precursory observations. The present study describes the food capture behavior of Leposternon microcephalum Wagler, 1824 in captivity. In this experiment we used non-live bait (moist cat food), which was placed near a burrow opening, on the surface of the substrate. Three animals were monitored visually and filmed using cellphone cameras deployed at fixed points, to capture images from the dorsal and lateral perspectives of the study subjects. Two principal types of behavior were observed: the capture of food and defense mechanisms. The strategies used to capture the food were similar to those observed in other fossorial species. Although the backward movement has already been observed and described, we were able to record this movement being used as an escape strategy. These findings enrich our knowledge on different aspects of the natural history of the amphisbaenians.
