Description
An account of the resource
Avaliou-se o crescimento, a produção e o teor do óleo essencial de dois cortes de capim citronela em cultivo consorciado com algodoeiro colorido no semiárido. Para isso foram utilizados dois sistemas de consórcios (tratamentos): algodão colorido consorciado com capim citronela 3x1 e algodão colorido consorciado com capim citronela 1x1. A variedade de algodão colorido utilizada foi a BRS Rubi e as mudas de capim citronela foram produzidas no Horto de Plantas Medicinais da Unimontes. O delineamento experimental utilizado foi em blocos casualizados com dois tratamentos e 16 repetições. O experimento foi mantido em regime de sequeiro e foi avaliado a altura das plantas de capim citronela. Foram realizadas duas colheitas das folhas de capim citronela, sendo a primeira no momento da colheita da fibra do algodão e a segunda na rebrota do capim, seis meses após. Todas as plantas da parcela foram colhidas e as folhas frescas foram pesadas, no campo, com o auxílio de balança digital. Amostras das folhas colhidas foram retiradas e levadas para secagem em estufa com circulação forçada de ar a 35ºC até atingirem massa constante. Foi verificada a massa seca e posteriormente realizada a extração do óleo essencial pelo método de hidrodestilação em aparelho modificado de Clevenger. Os dados foram submetidos à análise de variância e as médias comparadas pelo teste Skott-Knott (p

Con base en información obtenida sobre los nombres de todas las plantas con DAP > 2.5 cm (Diámetro a la Altura del Pecho, medido a una altura de 1.3 m) dentro de 30 parcelas de 0.1 ha cada una, y sobre los suelos, la vegetación y el paisaje a lo largo de 8 transectos (entre 2 y 5 km de longitud cada uno), se describen los aspectos más importantes sobre la taxonomía botánica y el ordenamiento o jerarquización del medio ambiente desde la perspectiva de los Indígenas Miraña de la Amazonía central colombiana. A pesar de la pérdida cultural, algunos pocos ancianos guardan como parte de su tradición oral, los elementos básicos de un sistema complejo de conocimiento de su ambiente natural. Se detectó un alto grado de conocimiento sobre las especies vegetales silvestres, la existencia de sistemas nomenclaturales para éstas y para los suelos, y un reconocimiento organizado de paisajes fisiográficos y tipos de vegetación.We describe the most important aspects of Miraña's plant taxonomy, and landscape categorization. Data about plants' names (in 30 plots of 0.1 ha), was gathered from all individual plants with DBH > 2.5 cm (Diameter at Breast High, or 1.3 m above ground), and data about soils, forest types and landscapes was (in 8 transects of 2-5 km long each) was gathered from 8 transects of 2-5 km long each. In spite of cultural lost, complex knowledge about natural environment classification, it is present into the oral tradition keep in some elders' mind. We detected a high level of knowledge about wild plants, the presence of nomenclatural systems for plants and soil types, and organized landscapes and forest types systems.

An account of the resource
Se presenta el primer registro de la mascarita pico grueso (Geothlypis poliocephala) para la región del Eje Neovolcánico Transversal, México. Los sitios donde registramos/capturamos esta especie se encuentran en los suburbios de la ciudad de Morelia, 427 m arriba del ámbito altitudinal descrito para la especie. Esto puede deberse a 2 factores: 1) la urbanización que genera hábitats propicios para la especie en su periferia, y 2 ) el incremento de la temperatura en la región en la que se encuentra la ciudad de Morelia. Ambos factores facilitan que esta especie de tierras bajas pueda habitar en áreas de mayor altitud. Así, nuestros registros sugieren que la mascarita pico grueso puede catalogarse como especie potencial a utilizar hábitats suburbanos cuando éstos son similares a los hábitats en los que se distribuye de manera natural.The first record of the Grey-crowned Yellowthroat (Geothlypis poliocephala) in the Transmexican Volcanic Belt biogeographic region (Mexico), within the Morelia city suburbs is presented. Sites were this parulid was sighted / captured were located 427 m higher than its described altitudinal range. This could be due to 2 factors: 1) urbanization generates suitable habitats for this species in periurban areas, and 2) temperature values have increased in the region where the city of Morelia is located. These factors allow that a lowland bird species can inhabit in more elevated areas. Thus, our records suggest that the Grey-crowned Yellowthroat can be catalogued as potential to use suburban environments when these are similar to those used by the species on its natural distribution area.

Description
An account of the resource
A alimentação de peixes e os padrões ecomorfológicos estão relacionados com vários fatores como ontogenia. O presente trabalho foi realizado a fim de testar a hipótese de que a dieta e os padrões ecomorfológicos apresentam correlações positivas entre os diferentes estágios de ontogenia de Plagioscion squamosissimus (Heckel, 1840), pois à medida que a espécie passa da fase jovem para adulta altera a sua alimentação e morfologia. A pescada foi escolhida por ser a espécie mais abundante no reservatório da Estação Ecológica de Tapacurá, Estado de Pernambuco. Os padrões ecomorfológicos foram avaliados e relacionados com a alimentação dos indivíduos capturados no reservatório no mês de abril de 2013. As medidas morfométricas foram retiradas de todos os indivíduos capturados e posteriormente recolhidos seus estômagos. Os peixes foram separados de acordo com a fase de desenvolvimento, juvenis e adultos. Também foram tomados seu peso total, comprimento padrão e aferidas onze medidas lineares, utilizadas para obter os índices que representam os atributos ecomorfológicos. Os itens alimentares foram identificados e separados até menor nível taxonômico possível, sendo o mais frequente o camarão Macrobrachium amazonicum (Heller, 1862). Foi possível observar que nos juvenis os itens ingeridos apresentavam maior amplitude no tamanho em comparação com os adultos. Dos dados morfométricos observa-se que os valores de largura da cabeça são maiores nos juvenis e os valores da altura do corpo são mais elevados nos adultos, sendo estes fatores importantes para determinar o tamanho da presa ingerida pelo peixe. Conclui-se que a espécie Plagioscion squamosissimus mostrou relação positiva entre a morfologia e alimentação ao longo do desenvolvimento ontogenético evidenciado pela variação de comprimento dos itens ingeridos entre juvenis e adultos, porém não houve distinção em relação ao alimento ingerido entre eles.

OBJETIVO: Analisar a evolução dos preços relativos dos grupos de produtos alimentares e sua influência nas políticas públicas para uma alimentação saudável. MÉTODOS: Foram analisados dados do município de São Paulo de 1939 a 2010, a partir da aplicação de métodos de cálculo de números-índices. Foram utilizados dados do banco de preços e estruturas de ponderação da Fundação Instituto de Pesquisas Econômicas (1939 a 1988) e do Instituto Brasileiro de Geografia e Estatística (1989 a 2010). O banco de preços foi organizado, sua consistência foi testada e os preços foram deflacionados pelo Índice de Preços ao Consumidor. Os dados relativos a preços deflacionados foram calculados e agregados por categorias e grupos alimentares da pirâmide alimentar adaptada. Os índices de preços de cada grupo foram construídos aplicando a fórmula de Laspeyres modificada. O índice geral de preços da alimentação foi comparado com índices de cada grupo alimentar e respectiva categoria: alimentos in natura; alimentos industrializados; bebidas; carnes, leguminosas, leite e ovos; cereais e tubérculos; e refeições fora do domicílio. RESULTADOS: Os grupos alimentares de gorduras, óleos, condimentos, açúcares e alimentos processados (alimentos industrializados) apresentaram tendência de redução de preços em termos relativos. O índice dos alimentos in natura, como frutas e verduras, apresentaram tendência de elevação de preços. Outros grupos alimentares, como cereais, farinhas e massas, carnes, leite e ovos, apresentaram estabilidade de preços relativos ao longo do tempo. CONCLUSÕES: A evolução dos preços relativos dos alimentos no município de São Paulo mostra tendência desfavorável à manutenção da alimentação saudável em nível domiciliar em longo prazo.

Description
An account of the resource
O projeto de policultivo de carpas chinesas se destina a pequenos produtores rurais e pescadores artesanais dos municípios de Rio Grande e São José do Norte, selecionados por critérios técnicos e sócio-econômicos, visando à implantação de 20 viveiros com 0,5ha. Uma cooperativa de produção, beneficiamento e comercialização do pescado, diversificará a atividade rural, gerando renda e contribuindo para um sistema de produção coletivo, economicamente viável e ambientalmente sustentável com a obtenção de produtos com valor protéico de qualidade. Então, este estudo tem por objetivo organizar os itens de produção do projeto da FURG e realizar uma análise econômica, caracterizando o mérito deste tipo de produção no mercado (indicadores de mérito: Período de Retorno do Capital, Rentabilidade Simples e Índice de Lucratividade, para um viveiro de 0,5ha, considerando apenas a produção de peixe vivo, durante o período de 12 meses). Os resultados demonstram que em 2,38 anos os pequenos produtores rurais e os pescadores artesanais, estariam recuperando o capital investido. Isso se evidencia com o valor de 0,42, estimado para a rentabilidade simples, em um ano, para cada unidade na qual foi investido, obtendo-se um retorno de 0,42; tornando o policultivo de carpas chinesas uma boa fonte alternativa de renda.

An account of the resource
Los acridios figuran entre los invertebrados herbívoros dominantes en la mayoría de los sistemas de pastizal. Si bien, en Argentina, la importancia económica de estos insectos ha sido reconocida desde el siglo XIX, aún se desconocen aspectos importantes de la biología y ecología de la mayoría de las especies. El objetivo principal de este estudio fue determinar cómo la riqueza de especies, la composición y la densidad de acridios variaron en las comunidades vegetales más características del Sur de la provincia de Buenos Aires, durante cinco temporadas sucesivas (2005-06 hasta 2009-10), un área históricamente afectada por estos insectos. Se colectó un total de 22especies. La riqueza de acridios fue similar entre las diferentes comunidades vegetales, observándose una disminución significativa de la misma durante la última temporada de muestreo. La densidad total de acridios aumentó significativamente en todas las comunidades vegetales durante el estudio, alcanzando niveles de explosión poblacional (“outbreak”) en las últimas dos temporadas. En la de 2009-10, la densidad fue ocho veces mayor que en 2005-06. Las especies que más aportaron a este aumento en la densidad fueron Dichroplus maculipennis (Blanchard) y Borellia bruneri (Rehn). Dichroplus maculipennis resurgió como el acridio plaga más perjudicial en la región Pampeana, con el desarrollo de un “outbreak” de magnitud histórica, se registraron, en algunos sitios, densidades de hasta 75 ind/m2.

Description
An account of the resource
El Embalse del Neusa es un cuerpo de agua oligo-mesotrófico ubicado en la cordillera oriental de los Andes colombianos, utilizado en la regulación de caudales del río Neusa y en la distribución de agua para consumo. Allí se analizaron la variación espacial del nitrógeno y el fósforo y sus tasas de sedimentación, se indagó sobre su relación con la distribución de Egeria densa en el embalse. Para hacer una aproximación a la incidencia de las comunidades litorales sobre la variación del nitrógeno y fósforo se hicieron estimaciones de los porcentajes de nitrógeno y fósforo contenidos tanto en la biomasa como en la necromasa macrofíticas y se estudió su variación en el tiempo durante los procesos de descomposición in situ. En este trabajo se encontró que las diferencias temporales y espaciales en los contenidos de nitrógeno y fósforo en la columna de agua respondieron a las fluctuaciones estacionales de las afluencias y cambios de nivel del agua, así como a la distribución espacial de E. densa;. esta última se relacionó con el aumento en las tasas de sedimentación del seston, nitrógeno y fósforo. Durante la descomposición estos dos nutrientes se perdieron rápidamente en los primeros días, volviéndose limitantes para los microorganismos descomponedores en fases posteriores del proceso. Estos recurren a nutrientes disueltos, escasos en la columna de agua, que en consecuencia pueden ser limitantes para los procesos de descomposició.

Description
An account of the resource
La vegetación riparia es primordial para el funcionamiento de los ecosistemas acuáticos al aportar materia orgánica. Dado que el perifiton juega un rol indispensable en la dinámica de estos ecosistemas y existen pocos trabajos sobre su ecología en el Neotrópico, se planteó la pregunta: ¿Cómo afecta el tipo de cobertura vegetal de la zona riparia, la estructura del fitoperifiton de humedales de la Orinoquía? En noviembre de 2016 se estudiaron 15 humedales con cobertura boscosa y 15 humedales con vegetación herbácea en su zona riparia. Los humedales están ubicados en la zona periurbana de Villavicencio, Meta (Colombia). Se comparó la diversidad algal entre coberturas riparias y se realizaron análisis de Redundancia para determinar que variables ambientales explicaban la composición del fitoperifiton. Se encontraron 467 morfotipos de algas, el 36,2 % perteneció a la clase Zygnematophyceae, 35,3 % a Bacillariophyceae y 16 % a Chlorophyceae. En cuanto a las diatomeas, se encontraron 165 morfoespecies distribuidas en 30 géneros. Eunotia y Pinnularia fueron los más representativos. Los análisis multivariados indicaron que la composición de diatomeas se relacionó con la cobertura vegetal litoral y el carbono orgánico total. El resto del fitoperifiton fue explicado por la temperatura y la conductividad. Modelos de regresión lineal mostraron que la diversidad de diatomeas fue explicada por el número de sustratos, la temporalidad y la cobertura vegetal riparia. Los resultados permiten concluir que en humedales antropizados de la Orinoquía colombiana, el tipo de cobertura vegetal riparia afecta la composición y diversidad de las diatomeas.

Description
An account of the resource
Every time becomes more evident that the greater problems of our time cannot be understood separately. The increasing changes in the surroundings, as well as in the society, are taking to see the necessity to jointly have a transformation of values, nonsingle by the ecological good, but by the one of the same humanity. In the present investigation the conceptions that have the students of secondary approaches del environment and its deterioration, like the perception of educational in relation with their performance in the formation in values and attitudes in the secondary education are identified thus, with the aim to contribute to a change of attitudes that foment the care del surroundings and, by, to elevate the levels of the quality of life. For the data collection the natural semantic networks and the semistructured interview were used, the first instrument provided the approach towards the joint of the meaning constructed by the students in relation to the environmental deterioration, whereas the interview allowed the evaluation of the educational perspective in the boarding of this cognitive dimension in the educative process.
