Los pastos marinos son ecosistemas costeros de alta productividad, con gran diversidad y abundancia de peces, la cual es aprovechada por pescadores artesanales. En este estudio se analizó la estructura comunitaria íctica de praderas de Thalassia testudinum en Manzanillo (M) y La Brea (LB), costa noroeste del Golfo de Cariaco, Venezuela. También, se realizaron muestreos mensuales (11-2006 al 10-2007), con la utilización de una red playera. Se capturaron 34 810 organismos agrupados en 13 órdenes, 36 familias y 83 especies. En ambas zonas, el número de especies fue similar, aunque el número de organismos vario, y se encontró para M un total de 55 especies y 13 210 organismos y para LB 58 especies y 21 600 organismos. Las especies más abundantes y de mayor biomasa en el área muestreada fueron: Nicholsina usta, Haemulon boschmae, H. steindachneri, Harengula jaguana, Halichoeres bivittatus y Hemiramphus brasiliensis. Los visitantes ocasionales fue el componente comunitario más frecuente con 59%, los cíclicos y los residentes permanentes obtuvieron 22 y 19%, respectivamente. En M la H’n fue de 1.71±0.64bits/ind; entretanto en LB fue 1.95±0.51bits/ind. Los valores de la diversidad estuvieron relacionados directamente con la equitabilidad e inversamente con la dominancia. Los bajos valores del índice de similaridad, entre localidades permite establecer que estas comunidades ícticas son disimiles, debido quizás a la estructuración de cada pradera de Thalassia y a la conectividad con otros sistemas.Ichthyc biodiversity of seagrass meadows from the Northwest coast of Cariaco Gulf , Venezuela. Seagrasses are highly productive coastal ecosystems with a high diversity and abundance of fishes, very important to support artisanal fisheries. We analyzed the fish community structure of Thalassia testudinum in the communities of Manzanillo (M) and La Brea (LB), Northwest coast of Cariaco Gulf, Venezuela. Samples were taken monthly (Nov. 2006-Oct. 2007) from each place, using a beach net. A total of 34 810 fishes were captured, grouped into 13 orders, 36 families and 83 species. In both areas (M and LB), the number of species was similar, but a variation in their abundance was found: a total of 55 species and 13 210 organisms for M, and 58 species and 21 600 organisms for LB. The most abundant species and those with the highest biomasses in both areas were: Nicholsina usta, Haemulon boschmae, H. steindachneri, Harengula jaguana, Halichoeres bivittatus and Hemiramphus brasiliensis. The occasional visitors were the most frequent community components with a 59%, the cyclical and permanent residents were represented by the 22% and 19%, respectively. The H’n average for M was of 1.71±0.64bits/ind., while for LB was of 1.95±0.51bits/ind. The diversity values were directly related to the evenness and inversely related to the dominance. The low values of similarity indexes among localities allow us to assert that these fish communities are dissimilar, because of the structure of each Thalassia meadow and their connectivity with other systems.

El compost es una forma principal para degradar desechos de origen orgánicos; no obstante, todo el procedimiento requiere de largos tiempo de maduración por lo cual, es indispensable la búsqueda de formas rápidas para descomponer y transformar estos desechos en subproductos con alto valor agronómico. El objetivo de este estudio fue determinar el efecto de sustancias azucaradas en la descomposición de sustratos orgánicos para elaborar compost. Las sustancias investigadas fueron azúcar, melaza y jugo de caña (Saccharum officinarum), mezclados con un sustrato orgánico compuesto por 30% estiércol, 50% panca de maíz, 10% de restos de leguminosa, 9% de tierra y 1% de ceniza. El diseño experimental fue completamente al azar, con 16 unidades experimentales, un testigo absoluto y cuatro repeticiones. Las variables evaluadas fueron días para la descomposición, temperatura, humedad, peso del sustrato y contenido de nutrimentos. La melaza mezclada con residuos orgánicos disminuyó 6 días (9.68%) el período de descomposición, con relación al testigo (62 días). El tratamiento con melaza añadida presentó el mayor descenso de temperatura (8.7 ºC), aunque no se encontraron diferencias significativas entre tratamientos, al inicio y al final del ensayo. El contenido de humedad entre los tratamientos osciló entre 56.5 y 59.0%, sin embargo, las diferencias no fueron significativas. El tratamiento con melaza fue el que presentó la mayor pérdida de peso (10.8 kg) durante la descomposición del sustrato orgánico; no obstante, no hubo diferencias en el pH y contenido de nutrimentos (B, Ca, Cu, K, Mg, N, P, S, Zn, M.O.). El tratamiento con mayor concentración de nutrimientos fue el conformado por sustancias orgánicas y melaza, por lo cual, se recomienda su uso o integración para acelerar el proceso de descomposición en el compost.

Description
An account of the resource
As hortaliças são os alimentos que mais se destacam, em artigos científicos e em jornais, quando se trata de contaminação com agrotóxicos. Isso tem levado ao aumento na demanda por produtos orgânicos por parte dos consumidores. Há, então, a necessidade de se desenvolverem tecnologias que viabilizem esses sistemas, atendendo ao consumidor e melhorando a renda dos agricultores, geralmente de base familiar. A produção de hortaliças em sistema orgânico requer tecnologias que respeitem os processos ecológicos, que promovam o aumento da matéria orgânica do solo e que sejam poupadoras de energia. Neste artigo, são discutidas algumas dessas tecnologias e resultados de pesquisas, com foco em produção de mudas, manejo e adubação do solo, adubação verde, rotação de culturas, consórcio de hortaliças, manejo de plantas espontâneas e manejo de pragas e doenças, que são práticas aprovadas pelas normas para produção orgânica e seguem os princípios agroecológicos, que contribuem para a maior eficiência energética dos sistemas produtivos e, em conjunto, para o necessário desenvolvimento do setor de produção de hortaliças orgânicas com base científica.

Description
An account of the resource
Physical processes, biotic processes and human activities all act to shape marine ecosystems. Future management of these valuable ecosystems requires an integrative approach that takes into account complicated organismal interactions, oceanographic processes that span large scales of time and space, and how anthropogenic effects interact with the natural environment. The temperate west coasts of North and South America represent a unique opportunity for comparison, as many of the same oceanographic processes, particularly upwelling, occur off both coasts. Additionally, a number of marine ecosystems in both areas have surprising parallels. Here we present an overview of the oceanographic processes that dominate the coastlines, and give examples of ecosystems and the effects that oceanography, human activities and their interaction have on the communitiesLos procesos físicos y biológicos y las actividades humanas determinan los ecosistemas marinos. El manejo futuro de estos valiosos ecosistemas requiere de una aproximación integrativa que considere las complejas interacciones entre individuos, los procesos oceanográficos que se desarrollan a gran escala espacial y temporal, y la interacción de los efectos antropogénicos con el medio ambiente. Las costas templadas del oeste de Norteamérica y Sudamérica representan una oportunidad única para efectuar comparaciones ya que muchos procesos oceanográficos, particularmente la surgencia costera, ocurren en ambas costas. Adicionalmente, numerosos ecosistemas marinos en ambas áreas presentan sorprendentes paralelos. La presente revisión ofrece una visión general de los procesos oceanográficos dominantes en ambas costas y ofrece ejemplos de ecosistemas y los efectos que la oceanografía, las actividades humanas y las interacciones entre individuos tienen sobre las comunidades marinas

La ecología poblacional de los insectos de secano ha sido poco estudiada en Chile. Existen diferentes especies que habitan los interfluvios de la región desértico transicional que, bajo ciertas condiciones ambientales, irrumpen demográficamente. Una de estas especies es Elasmoderus wagenknechti (Orthoptera: Tristiridae). Esta es una especie endémica a Chile, su rango de distribución se extiende desde Taltal en la Segunda Región (2522' S, 7031' O) hasta Salamanca en la Cuarta Región (3146'S, 7058'O). En este trabajo se comunican y discuten los resultados de análisis morfométricos realizados en individuos adultos de E. wagenknechti. Estos fueron capturados durante dos eventos de irrupción poblacional ocurridos en 1996 y 1999 en la Cuarta Región (Coquimbo, Chile). Elasmoderus wagenknechti ha sido descrita como una especie braquíptera. En este estudio, la relación longitud del tegmen/longitud del abdomen fue 0,66 para el macho y 0,51 para la hembra. Para el ala metatorácica, esta relación fue 0,34 y 0,24 respectivamente. La variabilidad morfométrica de los 23 caracteres examinados resultó baja tanto en el macho (CV: 3,04-31,46 %) como en la hembra (3,68-32,00 %). A pesar del aspecto más grueso de la hembra, la relación ancho corporal/longitud total fue similar en ambos sexos (0,27). Del mismo modo, tanto en el macho como en la hembra, el nivel de hidratación bordeó el 71 % de la biomasa medida en fresco. En esta misma dirección, la relación biomasa seca/biomasa fresca fue similar en ambos sexos (e.g., 0,28 en el macho; 0,29 en la hembra). Las comparaciones morfométricas entre machos de diferente evento demográfico mostraron 10 diferencias significativas; las hembras, ocho diferencias. Además del tamaño (e.g., longitud total), el dimorfismo sexual quedó evidenciado en doce comparaciones morfométricas. La diferencia favoreció a la hembra en todos los casos. Los índices variable morfométrica / variable morfométrica más altos correspondieron al Ps (2,83), Lt (1,56), An mes (1,55) y Lpn (1,52), todos ellos relacionados al tamaño. El índice de condición fue ligeramente más alto en la hembra (beta1: 1,42) que en el macho (beta1: 1,25). Aunque esta diferencia no resultó estadísticamente significativa, un valor mayor del índice de condición de las hembras sugeriría una mejor adecuación biológica de estas respecto de los machos. Esta habilidad de la hembras explicaría la capacidad de E. wagenknechti de irrumpir demográficamente en el semidesierto de Chile, una vez dadas las condiciones ambientales favorables para ello.The population ecology of rangeland insects has been little studied in Chile. There are different species inhabiting the inter-valley areas of the transitional desert that, under certain environmental conditions, display population outbreaks. One of them is Elasmoderus wagenknechti (Orthoptera: Tristiridae). It is an endemic species to Chile. Its geographic range of distribution is from Taltal in the Second Region (2522'S, 7031' W) to Salamanca in the Fourth Region (3146' S, 7058' W). The results of morphometric analyses carried out on individuals captured from two population outbreaks are reported and discussed in this work. The outbreaks took place in 1996 and 1999 in the Fourth Región (Coquimbo, Chile). Elasmoderus wagenknechti has been described as a brachypterous species. In this work, the relation length of the tegmen/length of the abdomen was 0.66 for the male and 0.51 for the female. To the metathoracic wing, this relation was 0.34 and 0.24 respectively. The morphometric variability of 23 characters examined in this work was low both in the male (CV: 3.04-31.46 %) and in the female (CV: 3.68-32.00 %). Despite the thicker aspect of the female, the relation body width/total length was similar in both sexes (0.27). Likewise, the level of hydration was close to 71% of fresh biomass in both the male and the female. In the same way, the relation dry biomass/fresh biomass was also similar in both sexes (male: 0.28; female: 0.29). The morphometric comparisons from different outbreaks showed 10 significant differences in males and eight significant differences in females. Besides body size (e.g., total length), the sexual dimorphism showed up in 12 morphometric comparisons. In all of them, the difference was favorable to the female. The highest indices of morphometric variable / were dry weight (2.83), total length (1.56), mesonotal width (1.55), and pronotal length (1.52); all of them related to body size. The condition index was higher in the female (beta1: 1.42) as compared to that of the male (beta1: 1.25). Although this difference was not statistically significant, a higher value would suggest a better fitness of the female. This fact might explain the ability of this species to demographically outburst in the Chilean semidesert, once the right environmental conditions have been triggered.

RESUMO O uso de bioestimulantes tem se difundido na agricultura brasileira, promovendo o crescimento e aumento na produtividade das culturas, mas ainda são incipientes estudos sobre o uso destas substâncias em plantas sob estresse, principalmente sobre estresse salino. Objetivou-se avaliar o uso de bioestimulante como agente amenizador do estresse salino na cultura do milho pipoca. O experimento foi conduzido em ambiente protegido no Campus da Universidade Federal Rural do Semi-Árido, em Mossoró-RN. Utilizou-se o delineamento experimental inteiramente casualizado, com os tratamentos distribuídos em esquema fatorial 2 x 4, referentes a dois níveis de salinidade da água de irrigação (0,5 e 4,5 dS m-1) e quatro doses de bioestimulante aplicado via tratamento de sementes (0; 5; 10 e 20 mL kg-1 de sementes), com cinco repetições. Utilizou-se o bioestimulante comercial Stimulate® (0,009% citocinina, 0,005% giberelina e 0,005% de auxina) e as plantas foram coletadas aos 50 dias após a semeadura. Foram avaliadas as seguintes variáveis: altura de plantas, diâmetro do colmo, número de folhas, área foliar, massa seca de colmo, massa seca de folhas, massa seca de raiz, massa seca de pendão, massa seca total e área foliar específica. O uso de água salina na irrigação provocou redução na maioria das variáveis de crescimento do milho doce, independentemente do tratamento de sementes com bioestimulante. O tratamento de sementes com Stimulate® promove o desenvolvimento de plantas de milho pipoca, mais não inibiu nem amenizou o efeito da salinidade sobre as plantas.

A produção de biofertilizantes a partir de rochas é um processo prático que reduz o consumo de energia e aumenta a disponibilidade de nutrientes no solo. Realizou-se um experimento em campo, para avaliar a eficiência e o poder residual de biofertilizantes de rochas com fósforo (BP) e com potássio (BK) mais enxofre inoculado com Acidithiobacillus, aplicados em diferentes doses, para comparação com os fertilizantes minerais superfosfato simples (SFS) e cloreto de potássio (KCl), no rendimento da alface (cv. Crespa-Grand Rapids), em dois plantios consecutivos, e em alguns atributos químicos do solo (pH, Ca, Mg trocável, P e K disponível). Nos dois ciclos houve efeito dos biofertilizantes BP, BK, e dos fertilizantes solúveis SFS e do KCl no rendimento da alface. Os melhores resultados no 1º ciclo foram com os tratamentos SFS700 BK90, SFS700 BK60, e no 2º ciclo com BP700 BK90, SFS700 BK60, e com SFS700 BK90. Observou-se efeito residual quando aplicados os tratamentos BP1050 BK90 No pH do solo não houve efeito dos biofertilizantes, aplicados em mistura com húmus de minhoca, e verificou-se significativo aumento no P e K disponíveis no solo, especialmente para P no 2º ciclo. Concluiu-se que os biofertilizantes de rochas com P e K, em mistura com húmus de minhoca, podem ser usados como alternativa a fertilizantes minerais solúveis.Production of rock biofertilizers is a practical process which reduces energy consumption and increases nutrients availability in soils. A field experiment was carried out applying phosphate biofertilizer (PB) and potash biofertilizer (KB) from rocks plus sulfur with Acidithiobacillus, applied in different rates, comparing with the mineral fertilizers simple superphosphate (SFS) and potassium chloride (KCl), on yield of lettuce (cv. Crespa-Grand Rapids), in two consecutive crops and in soil chemical attributes (pH, and available P and K). A control treatment was added without P and K (P0K0). In the two consecutive crops the biofertilizers BP, BK, and chemical fertilizers SFS and KCl were effective on lettuce yield. In the first crop the best results were obtained with the treatments SFS700 BK90, SFS700 BK60, and in the consecutive crop applying the treatments BP700 BK90, SFS700 BK60 and SFS700 BK90. In the two crops the positive response of the PK biofertilizers and PK mineral fertilizers was evident. Residual effect was observed when the treatment BP1050 BK90 was applied. Soil pH was not affected by application of PK biofertilizers plus worm-compound, increasing available P and K, especially for available P in the consecutive crop. The PK rock biofertilizers, plus worm-compound, may be applied as an alternative to PK mineral soluble fertilizers.

Description
An account of the resource
Las enredaderas son elementos conspicuos de la flora de diferentes ecosistemas. Numerosos estudios basados en patrones de distribución y ecología de este grupo de plantas se han realizado a escala regional, se conoce poco sobre los factores que afectan su distribución a nivel local. Se estudiaron los requerimientos germinativos de 21 enredaderas del Bosque chaqueño serrano de Córdoba, las cuales fueron clasificadas en típicas de bosques, matorrales e indiferentes. Se llevaron a cabo experimentos de germinación en tres regímenes de temperatura (15-5ºC, 25-15ºC y 35-20ºC), en luz (12-12hr luz-oscuridad) y oscuridad permanente. Se registró el porcentaje final de germinación, el índice de germinación relativa a la luz (GRL) y la velocidad de germinación (T50). La temperatura fue el principal factor regulador del proceso germinativo. El GRL y el T50 no registraron diferencias entre fisonomías. Los patrones observados apoyan la idea de que la germinación de este grupo de plantas estaría respondiendo a factores macroclimáticos (estacionalidad del clima y las precipitaciones), más que a un microclima (factores asociados a la fisonomía del sitio). La composición diferencial de enredaderas en los parches de bosques y arbustos no estaría explicada por los factores estudiados, sino por características de las etapas posteriores a la semilla.Vines are conspicuous elements of floras in different ecosystems. Patterns of distribution and ecology of this group has been studied at regional scales, mainly in tropical areas, but less is known about factors affecting their distribution at smaller scales. In this study, the germinating requirements of common vines from two plant communities (open shrubland and woodland) in xerophytic mountain forests (Chaco serrano) were studied. A total of 21 species were selected and classified as typical of woodland, shrubland, or indifferent. Experimental treatments were three temperature regimes (15-5ºC, 25-15ºC and 35-20ºC), in light (12-12h daily photoperiod) and in continuous darkness. Total germination percentage, the relative light germination (RLG) and germination rate (T50) were recorded. Among results we found that the temperature was the main factor triggering the germination process. No differences in the mean RLG and T50 between woodland and shrubland patches were found. The patterns observed in this work support the idea that, independently of patch type, germination is associated with temperature of the time of the year when most of the rainfall occurs. Germination of the studied species would be responding to macroclimate’s factors (seasonality of climate and rainfall), rather than to a microclimate. This indicates that differences in species composition between patches would not be due to the factors studied, rather than to characteristics of the later stages of the cycle life.

Description
An account of the resource
Utilizo la perspectiva crítica ecológica para aproximarme a Los cuentos de la selva (1918) de Horacio Quiroga con el fin de reflexionar sobre lo que he denominado el decir ecológico. Este último implica analizar cómo, en lo dicho por los personajes-animales de los cuentos quiroguianos, se revela una forma de comunicación “selvática”. Los animales hablan, pero no como humanos. Usan las palabras, pero éstas, más que servir en la discusión de problemas históricamente relevantes para la humanidad (el alma, la razón, etc.), reflejan el suceder de la naturaleza. Las palabras funcionan como un ecosistema. Los diálogos de tigres y boas, las expresiones de los tucanes, etc., están determinados por una preocupación particular: la selva como acontecimiento. En tal caso, podríamos afirmar que Quiroga imagina la selva creando personajes capaces de “hablar el verde” y “dialogar el hábitat”.

Este estudo objetivou verificar a distribuição temporal e espacial de Eretmochelys imbricata (Linnaeus, 1766) e aspectos de sua biologia reprodutiva, tais como tempo de incubação, sucesso reprodutivo, biometria das fêmeas, número de ninhos e fecundidade. Os dados foram coletados de 2007 a 2010 nas praias de Muro Alto, Cupe, Merepe, Porto de Galinhas e Maracaípe, todas elas localizadas no município do Ipojuca, estado de Pernambuco, Brasil. Foram analisados comparativamente parâmetros relativos à biologia reprodutiva e áreas de nidificação da espécie. Eretmochelys imbricata foi registrada nidificando entre os meses de outubro a maio, totalizando 350 ninhos monitorados em três temporadas. Os picos de desova ocorreram de janeiro a março, revelando um padrão sazonal das desovas. Houve diferença significativa entre o número de ninhos nas temporadas. A praia de Merepe apresentou uma ocorrência elevada de ninhos (46 ninhos/km) em relação às demais praias monitoradas. Quanto aos aspectos da biologia reprodutiva, o sucesso reprodutivo foi 65,6%, e o intervalo do tempo de incubação de 54 a 56 dias. As medidas biométricas foram coletadas de 59 espécimes, e apresentaram média de 92,5 cm ± 4,5 para o comprimento curvilíneo da carapaça e de 83,4 cm ± 5 para a largura curvilínea da carapaça. Os resultados podem ser utilizados para subsidiar planos de conservação e demonstram que as praias registradas neste estudo têm relevância como áreas de nidificação para E. imbricata.This study aimed to verify the spatio-temporal distribution of Eretmochelys imbricata (Linnaeus, 1766) and aspects of its reproductive biology, such as incubation time, reproductive success, biometric measurements of females, number of nests and fecundity. Data were collected during 2007 to 2010, on the beaches of Muro Alto, Cupe, Merepe, Porto de Galinhas, and Maracaípe, all of them located in the city of Ipojuca, state of Pernambuco, Brazil. Parameters relating to reproductive biology and nesting areas of the species were comparatively analyzed. Eretmochelys imbricata was recorded nesting between October and May, when 350 nests were monitored through three seasons. The spawning peak happened from January to March, also revealing a seasonal pattern. The number of nests differed significantly between seasons. The Merepe beach presented an elevated occurrence of nests (46 nests/km) if compared to the other monitored beaches. On the aspects of reproductive biology, the reproductive success was 65,6% and the incubation time interval ranged from 54 to 56 days. Biometric measurements were collected from 59 specimens, resulting in an average of 92,5 cm ± 4,5 for the curved carapace length, and of 83,4 cm ± 5 for the curved carapace width. The results can be used for subsidize conservation plans and demonstrate that the beaches recorded in this study are relevant as nesting areas for E. imbricata.
