Description
An account of the resource
The association of wild grasses with diazotrophic bacteria in Brazilian biomes is poorly understood. The isolation and characterization of bacteria associated with wild grasses can contribute to understand the diazotrophic ecology as well as to identify bacteria with biotechnological applications. In this study, we isolated and characterized diazotrophic bacterial isolates from Oryza glumaepatula collected in Cerrado and Forest areas of the Amazon in Roraima State, Brazil. Healthy O. glumepatula plants were collected at five sampling sites at Forest and seven at Cerrado, respectively. The plants were collected at the Cerrado areas in September 2008 while the Forest plants were collected in June/2008 and April/2009. The plants and the soil adhering to the roots were transferred to pots and grown for 35 days in greenhouse conditions. During the harvest, the shoots and the roots were crushed separately in a saline solution; the suspension was diluted serially and inoculated in Petri dishes containing Dyg’s medium. All distinct bacterial colonies were purified in the same medium. The diazotrophic capacity of each bacterium in microaerophilic conditions was assessed in semisolid BMGM medium. In addition, the pellicles forming bacterial isolates were also evaluated by PCR amplification for nifH gene. The diversity of nifH+ bacteria was analyzed by Box-PCR fingerprinting. For selected strains, the growth promoting capacity of O. sativa as a model plant was also evaluated. A total of 992 bacterial isolates were obtained. Fifty- one bacteria were able to form pellicles in the semisolid medium and 38 also positively amplified the 360bp nifH gene fragment. Among the 38 nifH+ isolates, 24 were obtained from the shoots, while 14 originated from the roots. The Box-PCR profiles showed that the bacterial isolates obtained in this study presented a low similarity with the reference strains belonging to the Herbaspirillum, Azospirillum and Burkholderia genus. The growth- promoting ability was confirmed for at least five isolates. For these bacteria, the root and shoot growing results showed higher increases when compared to those observed in plants inoculated with the evaluated reference strains. These results indicate that O. glumaepatula is colonized by a high diverse diazotrophic community in the Brazilian Amazon. Further investigations are now being carried out to determine the taxonomic positions of these isolates and their growth promoting mechanisms.La asociación de gramíneas silvestres con bacterias diazotróficas en los biomas brasileños es poco conocida. El aislamiento y caracterización de las bacterias asociadas con gramíneas silvestres puede contribuir a entender la ecología de las diazotróficas y bacterias con aplicaciones biotecnológicas. En este estudio, caracterizamos aislamientos bacterianos de diazotróficas de Oryza glumaepatula recolectadas en Cerrado y zonas boscosas de la Amazonía en el estado de Roraima, Brasil. Plantas sanas de O. glumepatula fueron recolectadas en cinco zonas boscosas y siete en Cerrado. Las plantas de Cerrado fueron recolectadas en septiembre 2008, mientras que las del bosque en Junio 2008 y Abril 2009. Las plantas y el suelo adherido a las raíces se transfirieron a macetas y se cultivaron durante 35 días en condiciones de invernadero. Durante la cosecha, los brotes y las raíces se trituraron por separado en una solución salina, la suspensión se diluyó en serie y se inocularon en placas Petri que contenían medio Dyg. Todas las colonias de bacterias se purificaron en el mismo medio. Se evaluó la capacidad diazotrófica de cada bacteria en condiciones microaerofílicas en medio semisólido BMGM. Además, los aislamientos bacterianos que formaron películas se evaluaron también mediante amplificación por PCR para el gen nifH. La diversidad de bacterias nifH+ se analizó por Huella Genética utilizando la Reacción en Cadena de la Polimerasa. Para las cepas seleccionadas, la capacidad de promover el crecimiento de O. sativa como modelo de planta también se evaluó. Se obtuvo un total de 992 cepas bacterianas. Cincuenta y un bacterias fueron capaces de formar películas en el medio semisólido y 38 amplificaron positivamente el fragmento 360bp del gen nifH. De los 38 aislamientos de nifH+, 24 fueron obtenidos de los brotes, mientras que 14 se originaron a partir de las raíces. Los perfiles de PCR-Box mostraron que los aislamientos bacterianos obtenidos en este estudio presentaron una baja similitud con las cepas de referencia pertenecientes a Herbaspirillum, Azospirillum y el género Burkholderia. La capacidad promotora del crecimiento fue confirmada por al menos cinco aislamientos. Para esta bacteria, la raíz y brote mostraron resultados de crecimiento mayores en comparación con los observados en las plantas inoculadas con las cepas de referencia. Estos resultados indican que O. glumaepatula es colonizada por una muy diversa comunidad diazotrófica en la Amazonia brasileña. Se están llevando a cabo otras investigaciones para esclarecer la taxonomía de estas cepas y sus mecanismos para promover el crecimiento.

An account of the resource
La Convención Marco de las Naciones Unidas sobre el Cambio Climático (CMNUCC), en su artículo 1, se define al cambio climático como el “... atribuido directa o indirectamente a la actividad humana que altera la composición de la atmósfera global y que se suma a la variabilidad natural del clima observada durante períodos de tiempo comparables...”. En las décadas recientes, las modificaciones en el clima han causado impactos en los sistemas naturales y humanos en todos los continentes y océanos. El cambio climático es un factor de riesgo para el éxito de las acciones encaminadas a la reducción de la pobreza, para la seguridad alimentaria, la salud pública, educación, en general para el desarrollo humano; elementos que de no atenderse aumentan la vulnerabilidad de la población. La CMNUCC reconoce que “...los países ubicados en altitudes bajas, los insulares pequeños, aquellos con zonas costeras bajas, las zonas áridas y semiáridas, o zonas expuestas a inundaciones, sequía, y desertificación, así como las naciones en desarrollo con ecosistemas montañosos frágiles son particularmente vulnerables a los efectos adversos del cambio climático”. Por su parte, el Grupo de Trabajo II del Panel Intergubernamental sobre Cambio Climático (IPCC, por sus siglas en inglés) concluye que este fenómeno “...tendrá los mayores impactos en aquellos pueblos con menos capacidad de protegerse contra el aumento del nivel mar, el incremento de enfermedades y la disminución de su producción agrícola”.

Description
An account of the resource
Knowledge of the feeding ecology of fish is essential for understanding the functioning of freshwater communities. Here we report on an analysis of the diet of Pachyurus bonariensis Steindachner, 1879, a freshwater sciaenid. Fish were collected bimonthly from December 1999 to January 2002 at three locations along the Ibicuí River in the Rio Grande do Sul State, Brazil. At each location, the specimens were collected in both lentic and lotic environments. The stomachs of 324 fish were analysed for contents and fullness. The main items were Ephemeroptera, Diptera (larvae), Trichoptera and Odonata. Annelida, plant matter, Decapoda, Diptera (pupae), Coleoptera and Mollusca were present in small amounts. The fish consumed smaller amounts of food in winter than in other seasons. The most important source of dietary variation for P. bonariensis was the ontogenetic, related to intrinsic biological characters. However, spatial variation was also found, suggesting that this species can adapt its diet to environmental changes. Although P. bonariensis showed ontogenetic and spatial variations in the main items consumed, the main items were always insects, characterising P. bonariensis as a fish with an insectivorous feeding habit in the Ibicuí River.A ecologia alimentar de uma espécie é muito importante para o entendimento do funcionamento das comunidades de água doce. Neste trabalho analisamos a dieta de Pachyurus bonariensis, um sciaenídeo restrito a ambientes dulceaquícolas. Os peixes foram coletados bimestralmente de dezembro de 1999 a janeiro de 2002 em três locais do rio Ibicuí no Estado do Rio Grande do Sul, Brasil. Em cada local os espécimes foram coletados em ambiente lótico e lêntico. Estômagos de 324 indivíduos foram analisados quanto ao seu conteúdo e grau de repleção. Os principais itens foram Ephemeroptera, Diptera (larva), Trichoptera e Odonata. Os itens Anellida, matéria vegetal, Decapoda, Diptera (pupas), Coleoptera e Mollusca estiveram presentes em menor quantidade. No inverno os peixes consumiram menor quantidade de alimento, quando comparado com as demais estações. A principal fonte de variação na dieta desse sciaenídeo foi proveniente de mudanças ontogenéticas, relacionadas a fatores biológicos intrínsecos. Entretanto também foi observada variação espacial na dieta de P. bonariensis, sugerindo que essa espécie pode adaptar sua dieta a mudanças ambientais. Apesar de P. bonariensis apresentar mudanças ontogenéticas e espaciais na sua dieta, os principais itens foram sempre insetos, caracterizando essa espécie como um peixe com hábitos insetívoros no rio Ibicuí.

Description
An account of the resource
The effect of degraded plastic with prodegradants on the polyethylene properties was studied. First, the mixture of low-density polyethylene (LDPE) with 5 wt.% prodegradant (oxo-degradable) additive was prepared by melt processing using a mixer chamber. Then, the degradation of the mixtures was evaluated by exposing the oxo-degradable LDPE in a Xenon arc chamber for 300 hours. The degraded material was characterized by infrared spectroscopy (FTIR) assessing the carbonyl index and the hydroperoxide band. Then, different percentages of degraded material (1, 5, 10, 20, and 50 wt.%) were incorporated into the neat LDPE. Mechanical and rheological tests were carried out to evaluate the recycling process of these blends. Also, the feasibility of the blends reprocessing was determined by analysing the melt flow index for each heating process and shear stress applied. It was evidenced that the increment of the content of the degraded material in the neat LDPE decreased the mechanical strength and the processability of blends due to the imminent thermal degradation. All the test results showed that the incorporation of degraded material causes a considerable reduction in the matrix properties during the reprocessing. Nevertheless, at low concentrations, the properties of the oxo-degradable LDPE–LDPE blends were found to be similar to the neat LDPE.

Este artículo examina la información que se ha producido en revistas arbitradas sobre las aves de las ciudades colombianas, complementando un artículo de revisión Latinoamericano publicado recientemente. Esta revisión identifica un total de 55 artículos en doce ciudades colombianas, lo cual excede en 50 el número de estudios previamente considerado. Los Listados de Especies y los Estudios Ecológicos son los estudios más frecuentes. La ciudad donde más trabajos se han realizado es Medellín (26), seguid por Bogotá (nueve), Cali y Popayán (ambas con cuatro trabajos). Aunque nuestra revisión registra un número mayor de publicaciones de lo que se asumía previamente, concluimos que la ornitología urbana colombiana es todavía una área joven, en tiempo, número, calidad, impacto y profundidad de las investigaciones publicadas hasta el momento.

A perda de florestas naturais devido a pressões antrópicas levou as florestas secundárias a ocupar uma grande proporção de áreas no leste da Amazônia. Com o objetivo de conhecer as características de uma comunidade arbórea e a estrutura populacional das espécies mais representativas, foram investigadas a riqueza de espécies, a estrutura e a composição florística de uma floresta secundária de 40 anos no município de Bragança (01°11'S e 46°40'W), Estado do Pará, Brasil. A amostragem contou com todos os indivíduos de espécies arbóreas (exceto Arecaceae) com DAP > 5 cm em 150 quadrados de 10×10 m. Foram registrados 2.934 indivíduos em 154 espécies, 101 gêneros e 40 famílias. A densidade foi de 1.956,00 ± 643,45 ind ha-1 e a área basal de 17,358 ± 7,952 m² ha-1 com um índice de diversidade de Shannon de 4,030 nats. ind.-1. As espécies com a maior abundância de indivíduos foram Myrcia bracteata, Casearia arborea e Maprounea guianensis. As com maior área basal foram Tapirira guianensis, Croton matourensis e Maprounea guianensis. A riqueza de espécies adaptou-se ao modelo de distribuição lognormal apenas para área basal e não para número de indivíduos. Em 40 anos de sucessão, esta floresta mostra uma grande diversidade de espécies e baixa área basal.The loss of natural forests due to the anthropic pressure carried the secondary forests to occupy great proportions of areas in East of Amazon. With the aim to known the characteristics of a arboreal community and the population structure of the most representative species, it were investigated species richness, structure, and floristic composition of a 40 years old secondary forest in the municipality of Bragança (01°11'S and 46°40'W), Pará State, Brazil. It was sampled all individuals of arboreal species (except Arecaceae) with DBH > 5 cm in 150 plots of 10×10 m. It was registered 2,934 individuals in 154 species, 101 genera and 40 families. The density was 1,956.00 ± 643.45 ind. ha-1 and the basal area of 17.358 ± 7.952 m² ha-1 with a Shannon diversity index of 4,030 nats. ind.-1. The species with the highest abundance of individuals were Myrcia bracteata, Casearia arborea, and Maprounea guianensis. The species with the highest basal area were Tapirira guianensis, Croton matourensis, and Maprounea guianensis. The richness of species fitted to the lognormal distribution model just for basal area and not for number of individuals. In 40 years of succession, this forest shows high species diversity and low basal area.

Description
An account of the resource
En este artículo analizamos, desde una óptica centrada en Europa, la evolución de las relaciones en la región mediterránea desde los primeros intentos de las comunidades europeas de formalización de acuerdos comerciales y desde los primeros pasos hacia la institucionalización de las políticas mediterráneas. En el ámbito del comercio de productos agrícolas argumentamos que la formulación de las diferentes iniciativas depende de criterios políticos y securitarios europeos. La política en materia de comercio de alimentos con los países vecinos de la orilla sur del Mediterráneo no se formula desde preocupaciones ligadas a la seguridad alimentaria ni al desarrollo económico de dichos países, sino que entran en juego intereses más conservadores en el ámbito de la seguridad y de la estabilidad, así como de la agenda normativa de la Unión Europea.

Description
An account of the resource
La preservación del suelo resulta prioritaria para todos los sectores de la sociedad, porque su deterioro repercute adversamente sobre otros componentes de la naturaleza y sobre los grupos sociales que necesitan del suelo. Por eso, es importante mantener la calidad y salud del suelo, para que la sociedad pueda garantizar su seguridad alimentaria y disfrutar de los servicios ecosistémicos que presta este recurso natural. En este artículo se revisan los conceptos centrales que buscan explicar las relaciones del suelo con la naturaleza y con las personas.
