FOOD SELECTION AND USE OF SPACE BY DIDELPHIS PERNIGRA (DIDELPHIDAE: MAMMALIA) IN AN ANDEAN SUBURBAN ENVIRONMENT
Authors: Suárez Cáceres Gina Patricia , Adinolfi Cristiano , Sánchez Barrera Francisco Alejandro 
Published: August 2020

Cities have grown throughout the Andes and we know little about the ecology of those species that tolerate them, limiting our options to do conservation. We applied optimal foraging theory to examine the behavior of the Andean White-eared Opossum (Didelphis pernigra), in a suburban area in Bogotá, Colombia. We used the giving-up density technique, which uses the amount of food left in a feeding patch, to evaluate whether the opossum’s foraging costs were affected by the height of food from the ground, and the quality and quantity of food. We also evaluated whether the spatial heterogeneity of the study site affected the opossum’s foraging. We used an artificial feeding patch to test these ideas. When food was either concentrated and, in less amount, (concentrated food) or diluted and more amount (diluted food), the opossums preferred to forage at 2 m than at 0.5 m, but concentrated food at 0.5 m was not significantly different from diluted food at 2 m. The opossums’ habitat use was affected by the spatial heterogeneity at the study site and animals preferred foraging along metal fences than on live fences made of trees. When a cable allowed connection between the metallic and live fences, the value of food patches at the live fence appeared to increase. Thus, although the opossums need resources associated with natural environments, our results suggest that there are human modifications that can benefit them, such as those that reduce the risk of predation and favor their mobility in suburban environments.

Los hongos formadores de micorrizas arbusculares (HFMA) son simbiontes obligados presentes en la rizósfera de plantas de cacao y la diversidad de sus comunidades se modifica, dependiendo de diversos factores como la presencia de cadmio (Cd) en el suelo. La persistencia de HFMA en suelos enriquecidos naturalmente con Cd podría ser un indicador de su capacidad para tolerar esta condición. Esta investigación caracterizó la estructura de la comunidad de HFMA locales presentes en la rizósfera de plantas de cacao en dos suelos con baja (B-Cd: 0,1 mg kg-1) y alta (A-Cd: 20,9 mg kg-1) concentración de Cd. Esporas de HFMA se identificaron mediante claves taxonómicas y su abundancia, riqueza y diversidad se determinó en muestras de suelo originales y después de su multiplicación mediante cultivos trampa. Las comunidades de HFMA se compararon usando análisis de componentes principales (ACP) e índices de diversidad alfa y beta. Los resultados indican que A-Cd presentó valores significativamente menores de abundancia (21 %), riqueza (20 %) y diversidad (11 %) de morfoespecies de HFMA con respecto a B-Cd. Las dos comunidades de HFMA presentaron cinco de siete géneros en común, pero solo cuatro de las 23 morfoespecies descritas se encontraron en ambas comunidades.El análisis de diversidad beta y el ACP determinaron baja similaridad y tasa de recambio entre las comunidades de HFMA. La dominancia de Diversispora spurca, Rhizoglomus sp. yClaroideoglomus etunicatumen A-Cd sugiere que estas morfoespecies son estrés-tolerantes y candidatos potenciales para el desarrollo de estrategias de mitigación en suelos con Cd.

Published: August 2020

La Serranía de La Lindosa es una formación geomorfológica que presenta heterogeneidad en sus coberturas vegetales. Esta zona se encuentra en una situación contradictoria debido a que presenta una elevada biodiversidad, sin embargo, es uno de los actuales focos de deforestación más grandes de Colombia. A pesar de que se espera una alta diversidad de murciélagos en La Lindosa existe poca información publicada sobre este grupo. Este trabajo presenta los resultados de inventarios de murciélagos realizados durante cinco años en la serranía de la Lindosa. Se compara la diversidad (riqueza, composición y estructura) de los ensamblajes de murciélagos en dos tipos principales de cobertura vegetal, los bosques húmedos y las sabanas casmófitas. Los inventarios recogen información de 735 murciélagos capturados, correspondientes a 46 especies. De éstas, 14 especies se encontraron solamente en sabanas casmófitas, 11 en bosques húmedos y 19 en los dos tipos de vegetación. De esta manera, se evidencia una alta complementariedad en la composición de especies de murciélagos entre los dos tipos de vegetación. Adicionalmente, la estructura de los ensamblajes de murciélagos varió entre los dos ambientes. La abundancia entre las especies es más homogénea en las sabanas casmófitas con un mayor número de especies raras comparado con los bosques húmedos. En general, la alta diversidad de murciélagos de la Serranía de La Lindosa puede estar relacionada con la heterogeneidad en la vegetación, la presencia de diferentes tipos de cuevas, y la historia evolutiva de las especies de murciélagos asociados a la Región Guayana.

Published: August 2020

High ammonia (NH4+) concentration can exert stress on many plants, which causes nutritional disorders and reduction on plant growth. However, depending on the intensity of the stress, it may be attenuated by silicon. In this work, the response of impact of cations and silicon accumulations and plant growth in cultivated papaya plants was investigated under different toxic ammonia concentrations regardless of the presence of silicon (Si). The experiment was conducted at the Universidade Estadual Paulista (UNESP) with papaya seedlings, variety ‘Grupo Formosa’ (Calimosa híbrida 01), grown in a glass greenhouse, in 1.7 dm3pots filled with pine and coconut fiber-based substrate. The experimental design was a randomized block design, in a 5 × 2 factorial arrangement. There were five ammonium concentrations: 10, 20, 40, 80, and 100 mmol L-1that were delivered via nutrient solution, in the absence and presence of Si (2 mmol L-1), with five replicates. After 31 days of growth, the cations and silicon accumulations in the shoot, plant height, stem diameter, root, and shoot dry matter were evaluated. Results revealed that increased ammonia concentration showed toxicity in papaya plants and stronger reductions in Ca, Mg, K and Si accumulations, plant heights, stem diameters, and root and shoot dry matter production, even when silicon was present and with greater effects on the shoot dry matter (87 %) than that of the roots (13 %).

Published: August 2020

Venezuela presenta un nivel de prevalencia intermedia de Hepatitis B, con cuatro focos de alta endemicidad asociados principalmente a población indígena. Las prevalencias halladas en el Amazonas venezolano tienen distintas distribuciones entre los pueblos, observándose diferentes particularidades epidemiológicas. El objetivo del presente trabajo fue reportar la prevalencia de VHB en población indígena de diferentes pueblos y regiones geográficas del estado Amazonas, que no habían sido evaluados hasta la fecha, mediante la determinación de los marcadores serológicos: Antígeno de Superficie del Virus de Hepatitis B (AgsHB) y Anticuerpos Anticore (Anti-HBc). Se estudiaron 1390 individuos de 15 pueblos indígenas (Baniva, Baré, Curripaco, Jivi, Mapoyo, Maco, Piapoco, Piaroa, Puinave, Sáliba, Warekena, Yabarana, Yanomami, Yekuana, Yeral), resultando una prevalencia de exposición al Virus de 37,6 % (Anti-HBc), y una prevalencia de infección activa de 5,6 % (AgsHB). La prevalencia de exposición al virus es proporcional a la edad. No se encontró diferencia significativa en relación al sexo. La exposición al virus en el pueblo Sáliba fue significativamente menor al resto de los pueblos indígenas (p<0,001), y la observada en Yabarana, significativamente mayor (p<0,001). Se encontró una prevalencia de AgsHB significativamente mayor (p<0,01) en el pueblo indígena Yabarana. Se puede predecir que existe relación entre prevalencia de exposición al virus de hepatitis B y la distancia geográfica al centro urbano.
NATURAL HISTORY OF THE BLACK IGUANA Ctenosaura similis (SQUAMATA: IGUANIDAE) IN ISLA CONTOY, QUINTANA ROO, MEXICO
Authors: García Rosales Aaron , Arriaga Noguez Alicia , Ramírez-Bautista Aurelio 
Published: August 2020

The genera Iguanaand Ctenosaurabelong to the Iguanidae family, and populations of most species of these genera have decreased due to anthropogenic effects. The natural history of most species of this family is poorly known, including Ctenosaura similis. Therefore, this study documents some ecological aspects of the species, such as its feeding habits, and habitat and microhabitat use in a population on Isla Contoy in Quintana Roo, Mexico. The data showed that even though C. similisis distributed throughout the island, individuals more commonly use human construction (buildings) of Parque Nacional Isla Contoy (PNIC) and mangrove areas. Microhabitats most used by all age classes and sexes were rocks and trees. The diet of the species is omnivorous; however, the frequency of prey type consumed changes with the age of the individuals (hatchlings, juveniles, and adults), as well as with the season of the year. The practice of cannibalism by some individuals is also reported, as well as coprophagy and scavenging. This work provides general information on the life history of C. similis, complementing the scarce information that is currently available.
Participation of NO in the vasodilatory action of isoespintanol
Authors: RINALDI Gustavo J. , ROJANO Benjamín , SCHINELLA Guillermo , MOSCA Susana M. 
Published: August 2020

Background: accumulating evidence suggests that natural compounds and specifically monoterpenes exert a vasodilator action. Objetive: to investigate the vascular effects of isoespintanol (2-isopropil-3,6-
dimetoxi-5-metilfenol, ISO) monoterpene isolated from the leaves of Oxandra cf xylopioides. Methods: thoracic aortic rings isolated from Wistar rats were contracted with KCl 80 mM and then relaxed by exposure to Ca2+-free solution in absence and in presence of ISO 0.6 mg/mL. The force/tissue ratio (F/W) and the time to obtain 50% of relaxation (T-50) were used to assess the maximal contractile response and the relaxation, respectively. To examine the participation of NO additional experiments were performed under inhibition of nitric oxide synthase with L-NAME (L-NG-Nitroarginine methyl ester). Results: ISO significantly decreased the F/W ratio (257 ± 19 vs. 360 ± 18) and did not change T-50. In presence of L-NAME the effects of ISO on contractile response was abolished. Conclusions: these results
demonstrate that ISO exerts a vasodilator effect through NO- dependent pathways and suggest that an inhibition of calcium influx could be the involved mechanism.

CONVERSION OF DURIAN SHELL AGROINDUSTRIAL WASTE INTO VARIOUS VALUABLE PRODUCTS TO SUPPORT THE FOOD SECURITY DURING THE COVID-19 NEW NORMAL ERA: REVIEW
Authors: Kusumaningtyas Ratna Dewi , Syah Ahmad Faiz Armiano 
Published: August 2020

<p>Durian (<em>Durio zibethinus Murray) </em>is a tropical, delicious and expensive fruit with specific aroma. Indonesia is among the biggest and the best durian fruit producer in the world. There are various types of Durian in Indonesia, coming from different areas. Based on the data released by the Central Bureau of Statistic, it was demonstrated that the main provinces producing durian in 2019 were East Java, Central Java, West Java, North Sumatera, West Sumatera, Banten, South Sulawesi, and South Sumatera with the total harvest of 289,334 ton, 172,939 ton, 94,183 ton, 90,105 ton, 62,564 ton, 46,436 ton, 45,729 ton, and 42,048 ton, respectively. The high production of durian fruit is beneficial for the agroindustrial and economic sectors. On the other hand, it also results in the abundance waste during the harvest time which causes many problems to the environment. The percentage of durian flesh of fruit is only 20.52%, meaning that the 79.48% of durian is unutilized parts such as shell and seeds. The waste resulted from durian is about 556,360 ton per year. Durian waste, especially durian shell, is difficult to degrade. Hence, the proper waste management of the durian shell is crucial. The strategic way to manage the durian shell is by upgrading this waste into various valuable products. In this work, the innovation of the durian shell waste conversion into diverse product to support the national food security during the covid-19 new normal era is discussed. Durian shell is potential to be used for the production of food products such as candy, pectin, edible film, and crackers, flour, and noodle. It also has potency to be utilized in the production of products which support the development of food crop agriculture and animal husbandry, such as biopesticides, organic fertilizer, and animal feed, which strongly associated with the food supply security.</p>

Data-Driven Prediction of Unconventional Shale-Reservoir Dynamics
Authors: Klie Hector , Florez Horacio 
Published: August 2020

Summary
The present work introduces extended dynamic mode decomposition (EDMD) as a suitable data-driven framework for learning the reservoir dynamics entailed by flow/fracture interactions in unconventional shales. The proposed EDMD approach builds on the approximation of infinite-dimensional linear operators combined with the power of deep learning autoencoder networks to extract salient transient features from pressure/stress fields and bulks of production data. The data-driven model is demonstrated on three illustrative examples involving single- and two-phase coupled flow/geomechanics simulations and a real production data set from the Vaca Muerta unconventional shale formation in Argentina. We demonstrated that we could attain a high level of predictability from unseen field-state variables and well-production data given relatively moderate input requirements. As the main conclusion of this work, EDMD stands as a promising data-driven choice for efficiently reconstructing flow/fracture dynamics that are either partially or entirely unknown, or that are too complex to formulate using known simulation tools on unconventional plays.
