Flipping the Tortilla: Social-ecological innovations and traditional ecological knowledge for more sustainable agri-food systems in Spain

The conventional dominant global agri-food system is a main driver in the Anthropocene: food production entails profound global environmental changes from greenhouse gas emissions to biodiversity loss, and shifting diets further impact planetary and human health. Innovative approaches are needed to shift towards more sustainable, equitable and healthy agri-food systems. Building on the increasing recognition of the relevance of traditional agroecological knowledge (TAeK) in sustainable food systems, this paper aims to describe innovative agri-food initiatives and explore how the use and valorization of TAeK may transform conventional agri-food systems. It employs a case-study approach in Spain, where we conducted semi-structured interviews with 12 representatives of alternative agri-food initiatives. We found that, to promote sustainable agri-food systems, TAeK has to span from farm-to-fork. Innovative agroecological practices and knowledge help to safeguard biocultural diversity, while gastronomic knowledge among consumers on how to process and prepare local varieties and species is crucial for the implementation of shorter value chains. We discuss how TAeK enhances the success of conventional systems of innovation, challenging dominant epistemological frameworks. By scaling deep (changing values), scaling out (dissemination, reproduction) and scaling up (changing institutions), the agri-food initiatives may act on leverage points to enable broader transformation of the Spanish agri-food system

Modeling the variance-covariance matrix of genetic and residual effects in a Panicum maximum genome wide selection experiment.

Panicum maximum stands out among the tropical forage species due to its high biomass yield and excellent nutritional quality, providing high animal performance. The improvement of sexual plant population of P. maximum by recurrent selection increases the probability of releasing superior cultivars. In this work, we aimed to model variance-covariance matrices for genetic (G) and residual (R) effects in a spaced plant experiment to obtain adjusted means that will be used in a recurrent genomic selection program

Correlation of the Indoor Air Quality Santriwati Dormitory with Acute Respiratory Infection at Raudhatul Ulum Islamic Boarding Schools and Al-ittifaqiah Islamic Boarding Schools in Ogan Ilir on 2015

Background: The high number of acute respiratory infection found in two islamic boarding schools specifically at Raudhatul Ulum Islamic Boarding Schools are 178 cases and 231 cases at Al-Ittifaqiah. Method: It was an observational research using cross-sectional design. Research sites at Raudhatul Ulum Islamic Boarding Schools and Al-Ittifaqiah Islamic Boarding Schools in Ogan Ilir. The population research was all santriwati both Islamic boarding schools that total sample 72 santriwati. The dependent variable in this study was santriwati incidence of respiratory infection, the independent variable was the physical quality of the air (temperature, lighting, humidity, rate of ventilation), the quality of biological air (number of bacterial air), residential density, sanitize behavior, and the behavior of openning window.The sample collection technique namely random sampling with the methods of sampling stratified. Data would be analyzed using chi square test. Result: The research result showed that there is significant correlation between temperature p= 0,013, residential density p= 0,003, sanitize behavior p= 0,001, and the behavior of opening a window p= 0,012 on the acute respiratory infection. There is no significant relationship in lighting p= 0,401, humidity p= 0,170, ventilation rate p= 0,489, and the germ air p= 0,170 as the acute respiratory infection. Conclusion: This research concluded that temperatur, residential density, sanitize behavior, and the behavior of opening window have significant correlation

Evidence of ongoing radial migration in NGC 6754: Azimuthal variations of the gas properties

Understanding the nature of spiral structure in disk galaxies is one of the main, and still unsolved questions in galactic astronomy. However, theoretical works are proposing new testable predictions whose detection is becoming feasible with recent development in instrumentation. In particular, streaming motions along spiral arms are expected to induce azimuthal variations in the chemical composition of a galaxy at a given galactic radius. In this letter we analyse the gas content in NGC 6754 with VLT/MUSE data to characterise its 2D chemical composition and H$\alpha$ line-of-sight velocity distribution. We find that the trailing (leading) edge of the NGC 6754 spiral arms show signatures of tangentially-slower, radially-outward (tangentially-faster, radially-inward) streaming motions of metal-rich (poor) gas over a large range of radii. These results show direct evidence of gas radial migration for the first time. We compare our results with the gas behaviour in a $N$-body disk simulation showing spiral morphological features rotating with a similar speed as the gas at every radius, in good agreement with the observed trend. This indicates that the spiral arm features in NGC 6754 may be transient and rotate similarly as the gas does at a large range of radii.Comment: 8 pages, 4 figures, accepted for publication in ApJL 2016 September 2

Rendimento corporal do cachara, Pseudoplatystoma fasciatum, cultivado em tanques-rede com diferentes densidades de estocagem.

Avaliou-se a influência de três diferentes densidades de estocagem sobre o rendimento corporal de cacharas cultivados em tanques-rede na região do Pantanal. The objective of this work was to evaluate the influence of three different stock densities on body yield of cacharas (Pseudoplatystoma fasciatum) raised in net cages

Desenvolvimento de produtos derivados do pescado a partir de Pacu cultivado no Pantanal.

O consumo de pescado vem aumentando significativamente no Brasil, em apenas três anos entre 2006 e 2009, o consumo aumentou 30%, indo de 7 Kg por habitante/ano para 9 Kg por habitante/ano (BRASIL, 2009). Vários fatores podem estar influenciando esse aumento, mas destaca-se o aumento da renda do brasileiro, decorrente do aquecimento da economia nos últimos anos e o aumento da oferta de pescado, reflexo do aumento da produção da aquicultura continental.bitstream/item/84624/1/COT93.pd

Resistência e mecanismos envolvidos em genótipos de milho em relação ao ataque do gorgulho, Sitophilus zeamais Mots. (Coleoptera: curculionidae).

A resistencia de 30 genotipos de milho ao ataque de Sitophilus zeamais Mots, foi avaliada em teste sem chance de escolha, sendo efetuada uma selecao de 10 deles (M 9560, XHT 12, A 952, AG 5011, X 9557, Z 8452, C 615, C 435, DINA 888, C 606), os quais foram submetidos ao teste com chance de escolha, avaliando-se a atratividade e a preferencia para oviposicao. Pelos resultados concluiu-se que os genotipos menos atrativos foram Z8452 (3,1%) e M 9560 (3,2%), enquanto o mais atrativo foi C 615 (24,7%). Os genotipos que apresentaram resistencia do tipo nao-preferencia para oviposicao foram A 952, M 9560 e XHT 12 com numeros medios de 2,0; 3,0 e 3,4 ovos por recipiente. A resistencia do tipo nao-preferencia para alimentacao e/ou antibiose foi observada nos genotipos M 9560, A 952 e Z 8452. Os genotipos com alta suscetibilidade ao gorgulho foram C 435, C 444, C 606 e AG 8010
