Title A name given to the resource Gut size flexibility in rodents: what we know, and don't know, after a century of research Flexibilidad en el tamaño del tracto digestivo en roedores: qué sabemos, y qué no sabemos, después de un siglo de investigación Creator An entity primarily responsible for making the resource DANIEL E NAYA Description An account of the resource Phenotypic plasticity comprises a central concept in the understanding of how organisms interact with their environment, and thus, is a central topic in ecology and evolution. A particular case of phenotypic plasticity is phenotypic flexibility, which refers to reversible change in organism traits due to changes in internal or external environmental conditions. Flexibility of digestive features has been analyzed for more than a century in a myriad of different species and contexts. Studies in rodents on gut size flexibility have been developed mainly from two different áreas of the biological sciences, physiology and ecology. However, as for several other topics related with physiological ecology, both kinds of studies largely developed along sepárate paths. Herein, I evaluate altogether the information belonging to both áreas. The major conclusions reached are: (1) there is a clear match between digestive morphology adjustments and change in environmental conditions, and gut size flexibility could be considered a widespread physiological mechanism oceurring in laboratory and wild species, and under laboratory, semi-natural and natural conditions. (2) For laboratory species, the experimental factors that have been more investigated are diet quality, reproductive status, environmental temperature and fasting, while for wild species the more analyzed factors are diet quality and temperature. (3) For wild rodent species, no differences in small intestine length flexibility between methodological approaches ñor species feeding categories has been identified. (4) It appears that high energetic demands are mainly coped with by changes at the small intestine level, while changes in the amount of undigestible material in the diet are mainly coped with by changes in the hindgut. (5) Change in gut length may be related to a decrease in food retention time (e.g., during diet dilution), while change in gut mass appears to be related to a need of higher specific absorption (e.g., during highly demanding periods). (6) The qualities of an energetic demand (e.g., its relative intensity) rather than simply its presence or absence can affect the amount of digestive flexibility. (7) Quantitative comparisons of the existing data are difficult due to several factors, such as the disparity of experimental treatments and differences in the types of data collected. At the end of this review, further directions for the study of digestive flexibility in rodents are presented.La plasticidad fenotípica constituye un concepto medular en el entendimiento de cómo los organismos interactúan con su ambiente y, por tanto, un tema central en ecología y evolución. Un caso particular de la plasticidad fenotípica es la flexibilidad fenotípica, la cual refiere a los cambios reversibles en un organismo producto de cambios en las condiciones ambientales. La flexibilidad en los rasgos digestivos ha sido estudiada por más de un siglo en diversas especies y contextos. Para el caso de los roedores, los estudios sobre la flexibilidad en el tamaño del tracto digestivo han sido desarrollados principalmente desde dos áreas de la biología, la fisiología y la ecología. Sin embargo, como ha ocurrido con muchos tópicos relacionados con la fisiología ecológica, ambos tipos de estudios se desarrollaron por vías separadas. En este trabajo se intenta evaluar de forma conjunta la información proveniente de ambas áreas. Las principales conclusiones alcanzadas son: (1) la flexibilidad en el tamaño del tracto digestivo puede ser considerada un mecanismo fisiológico ampliamente distribuido, existiendo un clara congruencia entre los ajustes en la morfología digestiva y los cambios en las condiciones ambientales. (2) Los factores experimentales más investigados han sido la calidad de la dieta, el estatus reproductivo, la temperatura ambiental y el ayuno para las especies de laboratorio y la calidad de la dieta y la temperatura para las especies salvajes. (3) En especies salvajes no se han encontrado diferencias en la flexibilidad del largo intestinal entre estudios con distintas aproximaciones metodológicas ni entre especies con distintos hábitos tróficos. (4) Los cambios en la demanda energética parecen ser principalmente afrontados mediante ajustes en el intestino delgado, mientras que los cambios en la cantidad de material indigestible en la dieta parecen ser principalmente afrontados mediante ajustes en el ciego e intestino grueso. (5) Los cambios en el largo del tracto digestivo parecen estar relacionados con la necesidad de ajustar el tiempo de retención del alimento (e.g., durante la dilución de la dieta), mientras que cambios en la masa del tracto parecen estar relacionados con la necesidad de modificar la tasa de absorción específica (e.g., durante un periodo de alta demanda energética). (6) Las características de una demanda energética (e.g., su intensidad relativa), más que su simple presencia o ausencia, pueden afectar la magnitud de los ajustes en las dimensiones del tracto digestivo. (7) A pesar de la gran cantidad de trabajos publicados, comparaciones cuantitativas de los datos existentes son difíciles de realizar, debido a factores tales como la disparidad en los tratamientos experimentales y en el tipo de información reportada. Para finalizar esta revisión se presentan nuevas direcciones en cuanto al estudio de la flexibilidad digestiva en roedores.

Title A name given to the resource Evapotranspiration and crop coefficient for potato in organic farming Evapotranspiração e coeficiente de cultivo da batata em sistema agroecológico de produção Creator An entity primarily responsible for making the resource Daniel F. de Carvalho, Dione G. da Silva, Hermes S. da Rocha, Wilk S. de Almeida, Eraldo da S. Sousa Description An account of the resource The aim of this study was to quantify the water consumption and the crop coefficients (Kc) for the potato (Solanum tuberosum L.), in Seropédica, Rio de Janeiro (RJ), Brazil, under organic management, and to simulate the crop evapotranspiration (ETc) using the Kc obtained in the field and the ones recommended by the Food and Agriculture Organization (FAO). The water consumption was obtained through soil water balance, using TDR probes installed at 0.15m and 0.30m deep. At the different stages of development, the Kc was determined by the ratio of ETc and reference evapotranspiration, obtained by Penman-Monteith FAO 56. The crop coefficients obtained were 0.35, 0.45, 1.29 and 0.63. The accumulated ETc obtained in the field was 109.6 mm, while the ETc accumulated from FAO's Kc were 142.2 and 138mm, respectively, considering the classical values and the values adjusted to the local climatic conditions. The simulation of water consumption based on meteorological data of historical series from 1961 to 2007 provided higher value of ETc when compared with the one obtained in the field. From the meteorological data of historical series, it was observed that the use of Kc recommended by FAO may overestimate the amount of irrigation water by 9%, over the same growing season.O trabalho foi desenvolvido visando a quantificar, sob manejo agroecológico, o consumo hídrico e os kcs para a cultura da batata (Solanum tuberosum L.), em Seropédica (RJ), e a simular a evapotranspiração da cultura (ETc), utilizando os kcs obtidos e os kcs preconizados pela FAO. O consumo hídrico foi obtido por meio do balanço hídrico do solo, utilizando sondas de TDR instaladas a 0,15 e 0,30 m de profundidade. Nas diferentes fases de desenvolvimento, o kc foi determinado pela razão entre a ETc e a evapotranspiração de referência, obtida por Penman-Monteith FAO 56. Os kcs obtidos foram 0,35; 0,45; 1,29 e 0,63. A ETc acumulada obtida em campo foi de 109,6 mm, enquanto as ETcs acumuladas a partir dos kcs FAO foram de 142,2 e 138,0 mm, respectivamente, considerando os valores clássicos e os corrigidos para as condições climáticas locais. A simulação do consumo hídrico com base nos dados meteorológicos da série histórica de 1961 a 2007 proporcionou valor maior de ETc quando comparado ao obtido em campo. A partir dos dados meteorológicos obtidos na série histórica, observou-se que a utilização de kcs preconizados pela FAO pode superestimar a quantidade de água na irrigação em 9%, considerando o mesmo período de cultivo.

Title A name given to the resource VARIABILIDAD ESPACIAL DE LAS BASES EN UN ANDISOL DE LA ZONA CAFETERA CENTRAL COLOMBIANA Creator An entity primarily responsible for making the resource DANIEL F. JARAMILLO J., SIAVOSH SADEGHIAN K., LUZ A. LINCE S. Description An account of the resource En una fi nca cafetera del departamento del Quindío, Colombia, se estudió la variabilidad espacial de las bases en Andisoles, haciendo un muestreo en red de 20x20 m. Los contenidos de bases se debieron transformar a logaritmo. Los logaritmos de Ca y Mg tuvieron tendencia espacial cuadrática, y ellos y el log K presentaron semivariogramas experimentales que sugieren una distribución en parches. Todas las variables presentaron covariables que cuando fueron incluidas, junto con la tendencia espacial, en el cálculo de los semivariogramas, acentuaron aún más el efecto parche en ellos. Se elaboraron mapas con diferentes grupos de datos y sistemas de interpolación para apreciar la distribución del contenido de las bases en el lote. Los tres mapas de log Ca y los tres de log Mg fueron muy similares entre sí y prácticamente zonifi caron el lote de igual manera. Los dos mapas de log K, elaborados con y sin covariables, fueron muy diferentes y produjeron dos zonifi caciones distintas. Según los mapas obtenidos, la fertilización con Mg y K puede hacerse con técnicas de manejo por sitio específi co. En cambio, con Ca debe hacerse una aplicación generalizada a todo el lote, basada en el promedio de su contenido, como se ha hecho tradicionalmente.

Estas nuevas perspectivas cobran especial relevancia en el contexto de crisis ecológica que caracteriza el Antropoceno, donde los pueblos indígenas buscan defender sus territorios frente a los proyectos extractivistas y de infraestructura. A través de la identificación de los modos de interacción que los kukama, un pueblo indígena del tronco tupí-guaraní, sostienen con espacios fluviales y terrestres propios del ecosistema de la llanura amazónica, encontramos procesos de domesticación y transformación de estos en territorios vitales. Consideramos que estas interacciones, basadas en las experiencias corporales, sensoriales y emocionales, configurarían una geografía afectiva que nos alienta a profundizar en los debates actuales de la geografía ambiental.

Title A name given to the resource Degradación física y química de dos suelos del cordón hortícola platense: Alternativas de tratamiento Physical and chemical degradation of two horticultural soils of La Plata: Alternative treatment Creator An entity primarily responsible for making the resource Daniel Fernández, Mabel Vázquez, Ricardo Andreau, Pablo Gelati, Mauro Provaza, Diego Bennardi Description An account of the resource La producción hortícola/florícola bajo cubierta requiere un manejo intensivo con riego, fertilizaciones y labranzas permanentes. Esto conduce a una degradación difícil de revertir. Entre las problemáticas se encuentran las derivadas de la sodicidad, salinidad, presencia de sustancias tóxicas para los vegetales, pérdida de materia orgánica y fertilidad física. Objetivos: a) evaluar el impacto progresivo hasta 21 años de uso intensivo bajo cubierta sobre diferentes propiedades químicas y físico-químicas en dos suelos del área; b) analizar el efecto de la aplicación de diferentes enmiendas orgánicas y químicas sobre variables químicas, fisico-químicas y físicas, en un suelo Argiudol vértico representativo de la región con 14 años de uso continuo en invernáculo, a los fines de seleccionar indicadores de calidad. Suelos: Argiudol vértico Serie Arturo Seguí. Antecedentes: 0 -21 años de cultivo bajo cubierta. Análisis: suelo (pH, conductividad eléctrica(CE), RAS, carbono orgánico total(COT) y particulado(Cp), N total(Nt), P extractable, NO3-, densidad aparente(Dap), porosidad (P), estabilidad estructural (DMP), agua de riego (CE, cationes y aniones), abonos orgánicos (materia orgánica, pH, Na, humedad). Tratamientos correctores: T0 (Testigo), T1 (Cáscara de arroz +Yeso+ Azufre), T2 (Compost + Yeso + Azufre), T3 (Cama de pollo + Yeso + Azufre), T4 (yeso), T5 (azufre), T6 (yeso + azufre). Se comprobó un deterioro progresivo de las cualidades productivas de los suelos a causa del aumento lineal del pH y curvilíneo de la sodicidad (RAS) y la salinidad (CE), disminución curvilínea del COT e incrementos irregulares de P extractable, muy elevados en algunos casos. Los tratamientos con agregado de cáscara de arroz y cama de pollo, ambos con adición de yeso y azufre fueron los más efectivos en términos generales para el control de la pérdida de materia orgánica (COT, CP) y propiedades físicas relacionadas (DMP, P, Dap) afectadas por el uso en un invernáculo con 14 años de antigüedad productiva.Horticultural and floricultural in greenhouse production requires intensive management with irrigation, fertilization and permanent tillage. This leads to irreversible soil degradation. Among the problems are those derived by sodicity, salinity, presence of toxic vegetables and loss of organic matter and physical fertility. Objectives: a) assess the impact of intensive greenhouse production of different chemical and physicochemical properties in two soils of the area during 21 years, b) analyze the effect of the application of different organic and chemical amendments on chemical, physical and physical-chemical variables on a Vertic Argiudol soil representative of the region with 14 years of continuous use in greenhouses, in order to select quality indicators. Soils: Serie Arturo Seguí. Antecedents: 0-21 years of cultivation under cover. Analysis: soil (pH, electrical conductivity (CE), RAS, easily oxidizable organic carbon (COT) and particulate carbon (Cp), total N (Nt), extractable P, NO3-, apparent density (Dap), porosity (P), structural stability (DMP)), water irrigation (CE, cations and anions), organic fertilizers (organic matter, pH, Na, humidity). Corrective treatments: T0 (witness), T1 (rice shell + gypsum + sulphur), T2 (compost + gypsum + sulphur), T3 (chicken bed (Cp) + gypsum + sulphur), T4 (gypsum ), T5 (sulphur), T6 (gypsum + sulphur). A progressive deterioration of the productive qualities of the soil was confirmed due to the linear increase of pH and sodicity curvilinear (RAS) and salinity (CE), curvilinear decrease of COT and extractable P increases irregularly, very high in some cases. Treatments with rice shell and chicken bed, both gypsum and sulfur addition, were the most effective for the control of the loss of organic matter (COT, Cp) and related physical properties (DMP, P, Dap) affected by use in a greenhouse for 14 years.

Title A name given to the resource Tratamento de sementes com bioestimulante ao milho submetido a diferentes variabilidades na distribuição espacial das plantas Creator An entity primarily responsible for making the resource Daniel Fernando Kolling, Luis Sangoi, Clovis Arruda de Souza, Diego Eduardo Schenatto, Willian Giordani, Cristian Majolo Boniatti Description An account of the resource RESUMO: A utilização de bioestimulantes pode auxiliar a mitigar os prejuízos ao milho, ocasionados pela má qualidade de estande. Este trabalho foi conduzido objetivando avaliar o efeito do tratamento de sementes com bioestimulante sobre o desempenho agronômico do milho, submetido a diferentes níveis de variabilidade na distribuição espacial das plantas na linha de semeadura. O experimento foi implantado em Lages, SC, durante o ano agrícola de 2013/2014. O delineamento experimental foi de blocos ao acaso, dispostos em parcelas subdivididas. Nas parcelas principais, testaram-se três níveis de desuniformidade espacial na linha: 0, 50 e 100% do Coeficiente de Variação (CV). No nível 0 % de CV, todas as sementes foram uniformemente distribuídas no sulco de semeadura, a uma distância de 17cm entre si. Nos demais níveis de CV, as distâncias entre sementes variaram conforme o tratamento. Nas subparcelas, testou-se a presença ou ausência do tratamento de sementes com bioestimulante. O aumento da variabilidade na distribuição espacial das plantas reduziu a área foliar e o teor de clorofila da folha índice no espigamento, bem como o diâmetro do colmo na colheita, independentemente do tratamento de sementes com bioestimulante. Isso contribuiu para reduzir o número de grãos por espiga e o rendimento de grãos dos tratamentos com 50 e 100% de CV na variabilidade espacial, tanto na presença quanto na ausência do bioestimulante. Portanto, o tratamento de sementes com bioestimulante não mitigou os prejuízos ao rendimento de grãos do milho ocasionados pela distribuição espacial irregular das plantas na linha de semeadura.

Title A name given to the resource ANÁLISE DOS SISTEMAS AGRÁRIOS DE TRÊS COMUNIDADES REMANESCENTES DE QUILOMBO NO VALE DO MUCURI, MINAS GERAIS Creator An entity primarily responsible for making the resource Daniel Ferreira Silva, Fabio Luiz Oliveira, Eva Aparecida Silva Description An account of the resource O presente artigo se propõe a realizar uma análise sistêmica da dinâmica produtiva de três comunidades remanescentes de quilombos na região sudeste do município de Teófilo Otoni, no Estado de Minas Gerais, por meio da utilização da metodologia de Diagnóstico dos Sistemas Agrários (DAS) junto às comunidades: Córrego Novo, Cama Alta e São Julião, situadas respectivamente a 40, 45 e 83 quilômetros da sede municipal. Para tanto, delimitamos o referencial teórico a conceitualização da Agricultura Familiar a fim de destacar desta categorização a perspectiva de ação das comunidades agrícolas remanescentes de quilombos, a partir do qual destacamos a importância do Estado no processo de fomento à produção agrícola e promoção socioambiental do campo brasileiro, em seguida definimos os parâmetros teóricos da análise sistêmica na qual o presente trabalho foi alicerçado. Por fim, concluímos que existe a necessidade de implantar estratégias de desenvolvimento rural sustentável que levem em consideração a geração de renda e respeito ao meio ambiente sob três aspectos: a diversificação produtiva, segurança alimentar da família e a produção de artesanatos.

Title A name given to the resource Políticas, enseñanza, investigación, redes y difusión ambiental Creator An entity primarily responsible for making the resource Daniel Florencio Lovera Dávila Description An account of the resource La Universidad Nacional Mayor de San Marcos tiene incorporado en su plan estratégico el compromiso ambiental, en la misión y visión se hace mención al compromiso de los alumnos con el medio ambiente. La acreditación nos impulsa a tomar en cuenta la dimensión ambiental. Las Escuelas Profesionales también consideran en su plan de estudios la temática ambiental; las líneas de investigación consideran las variables ambientales y de cambio climático; mientras que, las Unidades de Posgrado cuentan con sus diplomados, maestrías y doctorados en la resolución de la problemática ambiental. La incorporación de la temática ambiental es creciente y tiene gran interés por parte de la comunidad universitaria. Desde la oficina de cambios climáticos y gestión de riesgos se coordina y propicia la capacitación y formación del capital humano, tanto de estudiantes como docentes en la temática ambiental. En este marco global ambiental, el Instituto de Investigación de la Facultad de Ingeniería Geológica, Minera, Metalúrgica y Geográfica-FIGMMG; en conjunto con la Fundación Biosfera (Argentina) se unieron iniciativas y visiones para desarrollar el foro regional denominado Encuentro de Responsables Ambientales de provincias y estados de América Latina y el Caribe en forma permanente realizados los años 2014, 2015, 2016, y posteriores. Estas reuniones tuvieron lugar en dias previos a la cumbre mundial de cambio climático (COP), en donde se analizarón las problemáticas ambientales locales, regionales y a nivel mundial. Bajo esas políticas y normas internacionales, los docentes y los grupos de investigación universitarios vienen desarrollando una variedad de proyectos para adaptarnos a los cambios climáticos actuales, asi como trazar estrategias para mitigar dichas variaciones a nivel nacional e internacional. Los resultados de estas investigaciones se difundirán a través de publicaciones en la revista del Instituto de Investigación FIGMMG.
