An account of the resource
Entre los principales problemas sociales globales se encuentra el acceso a alimentos saludables. En Argentina, la problemática alimentaria se manifiesta principalmente como subconsumo de vitaminas y minerales y una alta tasa de obesidad, especialmente en sectores populares. Entre las alternativas de acceso a una alimentación saludable, se ha propuesta la Agricultura Urbana, específicamente las huertas familiares traspatio de base agroecológica. Este trabajo buscó indagar, a partir de un caso específico, sobre el aporte nutricional efectivo de una huerta traspatio agroecológica, especialmente en vitaminas y minerales, el grado de autoabastecimiento logrado para satisfacer las demandas alimentarias de una familia tipo y la superficie cultivada que sería necesaria para cubrir dicha demanda. Para ello se trabajó con la producción de una huerta de 152 m. ubicada en La Matanza (Buenos Aires) y sostenida por trabajo familiar. Se recabaron los datos de un año y se estimó el aporte anual en distintos minerales y vitaminas para cada especie cultivada. La productividad anual obtenida fue de 7,42 kg/m.. La oferta de vitaminas A, B9, K y C sería excedentaria para una familia tipo. El aporte de fósforo y hierro fue cercano al autoabastecimiento. Hubo déficits considerables en vitaminas E y K, mientras que el aporte más bajo fue de sodio, con 18% de las demandas diarias. Las superficies mínimas necesarias para cubrir las demandas familiares fueron muy variables, con 15,9 m. para vitamina K y 870,8 m. para los requisitos de sodio. Se determinó que las huertas traspatio pueden ser una fuente de provisión interesante en contextos urbanos, especialmente para ciertas vitaminas y minerales. Sería conveniente ampliar este tipo de trabajos a estudios transversales con representatividad estadística a nivel regional.

Esta pesquisa foi realizada com o objetivo de avaliar as conseqüências da adoção de um sistema de consórcio sobre a supressão das plantas daninhas e o conseqüente crescimento e produtividade da cultura do milho. Os tratamentos resultaram da combinação entre cinco níveis do fator plantas forrageiras (Brachiaria decumbens, Brachiaria brizantha, Panicum maximum, milho sem forrageira e em convivência com plantas daninhas e milho capinado) e três níveis do fator plantas daninhas (Ipomoea grandifolia - corda-de-viola, Amaranthus hybridus - caruru-roxo e Digitaria horizontalis - capim-colchão). Durante a condução do experimento avaliaram-se a área foliar (cm² por planta), a massa seca (g por planta) e o rendimento (t ha ¹) obtido pela cultura do milho, em cada tratamento. Pôde-se observar que a consorciação da cultura do milho com as plantas forrageiras, embora também provoque reduções de produtividade, atenua as perdas que ocorrem quando a cultura está em competição exclusiva com as plantas daninhas e garante o maior dinamismo, utilização e proteção do solo. Como conclusão geral, a pesquisa demonstrou a viabilidade da aplicação do sistema de consórcio, sobretudo no âmbito da agricultura familiar.The objective of this work was to evaluate the consequences of adopting a consortium system on weed suppression and consequent corn crop growth and yield. The treatments consisted of combinations of five levels of the factor grass forages (Brachiaria decumbens, Brachiaria brizantha, Panicum maximum, corn without forage and with weed competition and hand-weeded corn) and three levels of the factor weeds (Ipomoea grandifolia, Amaranthus hybridus and Digitaria horizontalis).Leaf area (cm² per plant), dry mass (g per plant) and yield (t ha-1) obtained by the corn crop were evaluated in each treatment. Although also causing yield reductions, corn crop consortium with the grass forages was found to attenuate the losses occurring when the culture is under exclusive competition, thus ensuring a greater soil dynamism, use and protection. The overall conclusion was that this work showed the viability of applying this consortium system, especially within the context of family farming.

Description
An account of the resource
Spatial variations of hermatypic coral assemblages were evaluated at five sites in Cayos Cochinos Archipelago, Honduras, in February 2008. Richness and coverage of corals and other benthic morpho-functional groups were estimated using 56 videotransects. Topographic complexity and depth were also measured by transect. Twenty-two coral taxa were recorded for Cayos Cochinos. Total species richness was similar (16 and 17 taxa) at all sites, whereas species richness by transect was different among sites (6-12 taxa). Shannon diversity showed weak differences among sites (1.46-2.13), whereas Pielou evenness was not different among sites. Simpson dominance was low with weak differences among sites (0.15-0.27). The total cover of hermatypic coral was 16.5% at Roatan Bank, 10.5% at Salamandinga, 9.7% at Punta Pelicanos, 7.6% at La Grupera, and 6.9% at Mariposales. The ANOSIM revealed assemblages of different corals between sites, except between La Grupera, Punta Pelicanos, and Salamandinga. The NMDS associated La Grupera, Punta Pelicanos, and Salamandinga given the greater contribution of Porites astreoides, Agaricia agaricites, and Montastraea annularis; whereas the NMDS differentiated Mariposales and Roatan Bank, which had more dissimilar assemblages with a greater predominance of Montastraea cavernosa, Agaricia agaricites, and Diploria labyrinthiformis. According to the BIO-ENV method, coral composition and abundance were correlated with the cover of articulated calcareous algae, sandy substrate, total hermatypic corals, rocky-calcareous substrate, fleshy macroalgae, and hydrocorals. In general, the differences found in the coral assemblages of Cayos Cochinos could be due to geomorphological characteristics as well as the effects of human activities in the study area.La variación espacial del ensamblaje de corales hermatípicos se evaluó en cinco sitios del archipiélago Cayo Cochinos, Honduras, durante febrero 2008. La riqueza y cobertura de corales y otros grupos morfo-funcionales bentónicos se estimaron con 56 videotransectos. La complejidad topográfica y profundidad fueron medidas por transecto. Se registraron 22 taxa de coral para Cayos Cochinos. La riqueza total fue similar para todos los sitios entre sí (16-17 taxa), pero la riqueza por transecto fue diferente (6-12 taxa). La diversidad de Shannon presentó diferencias significativas entre sitios (1,46-2,13), mientras que la equidad de Pielou no mostró diferencias. La dominancia de Simpson fue baja con diferencias entre sitios (0,15-0,27). La cobertura total de coral hermatípico fue de 16,5% en Roatan Bank, 10,5% en Salamandinga, 9,7% en Punta Pelicanos, 7,6% en La Grupera y 6,9% en Mariposales. El ANOSIM evidenció ensamblajes de coral diferentes entre sitios, excepto entre La Grupera, Punta Pelicanos y Salamandinga. El MDS asoció La Grupera, Punta Pelicanos y Salamandinga por la mayor contribución de Porites astreoides, Agaricia agaricites y Montastraea annularis, en tanto diferenció a Mariposales y Roatan Bank con ensamblajes más disímiles con una mayor dominancia de Montastraea cavernosa, Agaricia agaricites y Diploria labyrinthiformis. El método BIO-ENV mostró que la composición y abundancia de corales se correlacionaron con la cobertura total de algas calcáreas articuladas, arena, coral hermatípico, sustrato calcáreo e hidrocorales. En general, la variación de los ensamblajes de coral podría deberse a las características geomorfológicas y a los efectos de actividades humanas presentes en el área de estudio.

RESUMEN La epigenética, concepción frecuentemente atribuida a Corad Waddington (1905-1975), ha estado estrechamente relacionada a una lucha en el campo intelectual por más de dos mil años. Postulada por Aristóteles bajo la denominación de epigénesis, en oposición a la concepción biológica preformacionista de Demócrito, ha ido variando en sus contenidos y alcances en consonancia con el desarrollo del conocimiento científico. En la actualidad la epigenética se presenta en la literatura científica como un concepto con rasgos polisémicos y escasa integración conceptual. Sin embargo, la gran amplitud de fenómenos biológicos que abarca y la magnitud de la producción científica involucrada hacen necesario un nuevo acercamiento que integre ecología, evolución y desarrollo (eco-evo-devo). Se propone en este sentido conceptualizar la epigenética desde una perspectiva adaptativa, que implica la inclusión de mecanismos epigenéticos transgeneracionales o darwinianos, dependiendo del nivel de integración que se analice. Esto permitiría integrar conceptos y resolver contradicciones en áreas de la biología funcional y evolutiva ABSTRACT The epigenetic concept, frequently attributed to Corad Waddington (1905-1975), has been closely related to a fight in the intellectual field for more than two thousand years. Postulated by Aristotle under the name of epigenesis, as opposed to the biological preformationists conception of Democritus, it has varied in content and scope in accordance with the development of scientific knowledge. Today, epigenetics is presented in the literature as a polisemic concept with low conceptual integration. However, the wide range of biological phenomena covered and the extent of scientific production involved demand a new integrated approach to ecology, evolution and development (eco-evo-devo). In this sense, it is proposed to conceptualize epigenetics from an adaptive epigenetic perspective, which involves the inclusion of transgenerational epigenetic or Darwinian mechanisms, depending on the level of integration to be analyzed. This would allow to integrate concepts and solve contradictions in areas of functional and evolutionary biology.

Description
An account of the resource
I summarize what is known about the mediterranean ecosystem represented in San Carlos de Apoquindo (33º 23' S, 70º 31' W), a rugged area of 835 ha located ca. 20 km east of downtown Santiago on the Andean foothills. This site attracted numerous researchers during 1976-1990 because of its proximity to Santiago and its relatively protected status. I review the literature, and provide unpublished information on this site. A total of 132 literature entries describe the ecology of San Carlos de Apoquindo, in about 30 topics. The shrub and herbaceous vegetation have been well studied, but little is known about the respective seed banks. Among animals, small mammals, rabbits, and avian and mammalian predators are the best investigated, whereas epigean arthropods, amphibians, lizards, snakes, passerine birds, and scavengers of all types are the least studied. Thematically, interactions from plant/climate, to plant/soil, to plant/herbivore, to herbivore/predator interactions, and to decomposition of animal carcasses, have been addressed. But gross inequalities exist on the thoroughness with which each topic has been researched. The best studied aspects deal with plant/herbivore and herbivore/predator interactions. Up to now, no description existed of soils and climate in the area, which I present in this paper. Taking advantage of the long-term aspect of the research at the site, I highlight temporal variation patterns. And because of the different landscape aspects present at the site, I also highlight data that depict such spatial variability. In general, San Carlos de Apoquindo has contributed greatly to the understanding of ecological processes in central Chile. I call for renewed efforts at studying this site's ecology from an ecosystem perspectiveResumo lo que se conoce acerca del ecosistema mediterráneo representado en San Carlos de Apoquindo (33º 23' S, 70º 31' O), un área con alto relieve y de 835 ha localizada ca. 20 km al Este del centro de Santiago en la precordillera andina. Este sitio atrajo a numerosos investigadores durante 1976-1990 debido a su proximidad a Santiago y a su condición de relativamente protegido. Reviso la literatura y proveo información no publicada sobre este sitio. Un total de 132 referencias bibliográficas describen la ecología de San Carlos de Apoquindo, en alrededor de 30 tópicos. La vegetación arbustiva y herbácea han sido bien estudiadas, pero poco se sabe acerca de sus respectivos bancos de semillas. Entre los animales, los micromamíferos, conejos, y predadores rapaces y carnívoros son los mejor investigados, en tanto que los artrópodos epígeos, anfibios, lagartijas, culebras, aves paserinas y los carroñeros de todo tipo son los menos estudiados. Temáticamente, se han analizado interacciones planta/clima, planta/suelo, planta/herbívoro y herbívoro/predador, así como la descomposición de cadáveres animales. Sin embargo, hay desbalances grandes en la profundidad con que se han tratado estos tópicos. Los aspectos mejor estudiados se refieren a interacciones planta/herbívoro y herbívoro/predador. Hasta ahora, no existía descripción detallada de suelos y clima en el área, que aquí presento. Aprovechando el aspecto de largo plazo de la investigación en el sitio, destaco los patrones de variación temporal. Y aprovechando la presencia de diferentes unidades de paisaje en el sitio, también destaco su variabilidad espacial. En general, San Carlos de Apoquindo ha contribuído grandemente al entendimiento de los procesos ecológicos en Chile central. Llamo a realizar esfuerzos renovados para estudiar la ecología de este sitio desde una perspectiva ecosistémica

Description
An account of the resource
San Carlos de Apoquindo, en la precordillera de Chile central, es una localidad con estudios de larga data en vertebrados (ca. 30 años), situación favorable para el análisis de procesos de largo plazo que operan sobre dichos ensambles. En este contexto estudiamos la trayectoria del uso del suelo mediante imágenes satelitales LANDSAT, correspondientes a 1975, 1989 y 2003 y su presunto efecto sobre la vegetación, micromamíferos y aves rapaces. El análisis de las imágenes satelitales revela una expansión acelerada del área urbana en desmedro del suelo agrícola y matorrales naturales. Las especies de micromamíferos nativos de talla reducida y media no evidencian grandes variaciones de abundancia durante el período de estudio pero las de mayor tamaño redujeron sus poblaciones. El conejo europeo (Oryctolagus cuniculus) es una de las especies más abundantes del área, y estaría siendo favorecido por la modificación del paisaje. En la dieta del águila (Geranoaetus melanoleucus) y del peuco (Parabuteo unicinctus) se observó una disminución sostenida de la principal presa nativa, el degú (Octodon degus) y un aumento de la presa exótica, el conejo. Además se observó una tendencia a la disminución de la riqueza y abundancia de aves rapaces durante el período de estudio, la que se asociaría a la expansión urbana y al deterioro del matorral natural. Postulamos que la expansión urbana y la pérdida y fragmentación del matorral han producido una disminución de la población de degú, con su consecuente disminución en la dieta de águilas y peucos, lo que a su vez ha potenciado un incremento de depredación sobre conejo.San Carlos de Apoquindo, a piedemont area to the east of Santiago city, is a site with 30 years of data on vertebrates. Using LANDSAT satellite imagery for the years 1975, 1989 and 2003, we studied the spatio-temporal trajectory of land use and its putative effects on vegetation, small mammals and raptors. On the basis of a landscape-level analysis, we interpreted long-term trends in the abundance of small mammals and in the diet of raptors. Satellite imagery reveals an accelerated expansion of the urban area in detriment of agricultural land and native scrubland. Native mammal species of small and medium size do not display large variation of abundance during the 30 years study period, but larger-sized native mammals show reduced population numbers. The European rabbit (Oryctolagus cuniculus) currently is among the most abundant mammal species in the area, and seems to be favored by the temporal transition from dense to sparse scrubland. In the diets of Chilean Eagle (Geranoaetus melanoleucus) and of native Harris’ Hawk (Parabuteo unicinctus) there is a marked decrease of the native rodent prey Octodon degus and a concomitant increase of the exotic prey Oryctolagus cuniculus. In addition, there is a decreasing trend in richness and abundance of raptors throughout the study period, which is associated to both urban expansion and scrubland fragmentation and reduction. We propose that urban encroachment, together with areal reduction and fragmentation of native scrubland, has resulted in a decrease of the Octodon degus population, and in its subsequent decrease in the diet of both native eagles and hawks, which in turn has determined increased predation on exotic rabbits.
