| Fisheries make vital contributions to food security and food security is an important part of fisheries governance. However, there are relatively few in-depth studies examining the consequences of collapsed and changing fisheries for the food security of coastal communities. In this case study I use the concept of the coastal foodscape to look at the relationship between changing fisheries and community food security in the Bonne Bay region on the west coast of Newfoundland. I examine the social-ecological interactions that compose the local food system and their changing relationship to community food security, and point to directions for developing a more resilient and democratic food system. |

| Cardiac contusion is a potentially fatal complication of blunt chest trauma. The effects of a combination of quercetin and methylprednisolone against trauma-induced cardiac contusion were studied. Thirty-five female Sprague-Dawley rats were divided into five groups (n=7) as follows: sham, cardiac contusion with no therapy, treated with methylprednisolone (30 mg/kg on the first day, and 3 mg/kg on the following days), treated with quercetin (50 mg·kg−1·day−1), and treated with a combination of methylprednisolone and quercetin. Serum troponin I (Tn-I) and tumor necrosis factor-alpha (TNF-α) levels and cardiac histopathological findings were evaluated. Tn-I and TNF-α levels were elevated after contusion (P=0.001 and P=0.001). Seven days later, Tn-I and TNF-α... |

| Farming since 1983, Vehbi Ersoz always thought there were some problems with the conventional farming methods. Using a different pesticide for each varmint and a different fertilizer for each missing substance in the soil made him question the function and procedures in conventional agriculture. Favoring a more holistic perspective in agriculture, he tried many methods to enrich the soil and increase the soil microorganisms, which in turn do the actual work. In his region he brought many leading and innovative techniques to life. Some of them are greenhouse farming, organic farming, biodynamic agriculture and Shumei method of agriculture. As a side benefit of applying many different techniques, he discovered that methods applied in one philosophy, may in... |

| Environmental conditions ultimately leading to blooms of the toxic dinoflagellate Alexandrium catenella/tamarense were investigated at two Mediterranean sites (Annaba Bay, Algeria and Thau lagoon, France). Three years were examined in details: 1992 (a pre-Alexandrium period), 2002 (a year with the first bloom in Annaba) and 2010 (a year with a major bloom in Annaba). Most conditions were similar, but ammonium concentrations were much higher in Annaba (up to 100 μM) than in Thau (up to 10 μM). First records of A. catenella/tamarense were in 1995 for Thau and 2002 for Annaba, and coincided with soluble reactive phosphorus (SRP) decreasing below a concentration of about 1 μM. No other environmental variable could be related to those blooms. Thus, it is likely... |

| In the present work, abundance, spatial distribution and qualitative composition, of benthic marine litter, were investigated in five study areas from the Eastern Mediterranean and Black Seas (Saronikos, Patras and Echinades Gulfs; Limassol Gulf; Constanta Bay). Surveys were performed using the monitoring protocol proposed by the Technical Group for Marine Litter. Densities ranged from 24 items/km(2) to 1211 items/km(2), with the Saronikos Gulf being the most affected area. Plastics were predominant in all study areas ranging from 45.2% to 95%. Metals and Glass/Ceramics reached maximum values of 21.9% and of 22.4%. The size distribution of litter items showed that >= 50% fall into medium size categories (10 x 10 cm, 20 x 20 cm) along with an elevated... |

| Weeds are a major problem in organic or Nature Farming systems and mechanical methods are generally used for weed control. However either mulching or growing crop in-between rows of the principal crop offers scope as a means of protecting soil and suppressing weeds. Field studies thus evaluated the impact of either a mulch or growing two intercrops as possible management strategies for controlling weeds of vegetables grown in major and minor seasons of the tropics under a Nature Farming regime. All three strategies controlled weed numbers, their biomass and increased crop yields. However the least beneficial impact was from the dead leaf mulch, while the highest degree of weed control and increments in crop yields was with the green manure intercrop. The... |

| タイリクモモンガPteromys volansは，フィンランドやエストニア，韓国などでは森林分断化の影響による個体数の減少が危惧されている．北海道の十勝地方においても，過去の森林分断化によって生息地が減少した上に，現在でもさらに生息地の分断化・減少が進行している．本種に対する森林分断化の影響を評価するには，生息確認方法を確立し，生息状況をモニタリングする必要がある．本研究では，糞による簡便かつ効率的な生息確認方法を確立するために，糞が頻繁に発見される場所の特徴や糞の発見効率を検討した．11ヶ所の樹林地（面積0.42–13.69 ha）において，それぞれ10 mの調査ラインをランダムに12本引き，両側4 m（片側2 m）の範囲で糞の有無を確認した．全ての樹林地で本種の糞が発見され，1ヶ所の樹林地あたりの発見糞塊数は平均9.7個，発見ライン数は平均6.2本であった．糞は胸高直径が太い樹木の近くでよく発見され，胸高直径24 cm以上の樹木から20 cm以内の範囲で糞を探すことが効率的であることがわかった．一方で，樹林面積は糞の発見ライン数に影響しなかった．そのため，樹林面積の大きさによって，調査努力量を変える必要はないと考えられた．本調査の結果から，面積に関わらず1ヶ所の樹林地につき5本程度のラインを引いて糞を探すことで，簡便かつ効率的に本種の生息を確認できることがわかった． |

| Pushed by the Brazilian biodiesel policy, sunflower (Helianthus annuus L.) production is becoming increasingly regarded as an option to boost farmers' income, particularly under semi-arid conditions. Biodiesel related opportunities increase the demand for decision-making information at different levels, which could be met by simulation models. This study aimed to evaluate the performance of the crop model OILCROP-SUN to simulate sunflower development and growth under Brazilian conditions and to explore sunflower water- and nitrogen-limited, water-limited and potential yield and yield variability over an array of sowing dates in the northern region of the state of Minas Gerais, Brazil. For model calibration, an experiment was conducted in which two... |

| OBJECTIVES: Enterotoxigenic Escherichia coli (ETEC), a major cause of diarrhea in children under 5, is an important agent for traveler's diarrhea. Heat-labile enterotoxin (LT) and colonization factors (CFs) are two main virulence mechanisms in ETEC. CS6 is one of the most prevalent CFs consisting of two structural subunits viz., CssA, CssB, necessary for attachment to the intestinal cells.METHODS: In the present research, a chimeric trivalent protein composed of CssB, CssA and LTB was constructed. The chimeric gene was synthesized with codon bias of E. coli for enhanced expression of the protein. Recombinant proteins were expressed and purified. Mice were immunized with the recombinant protein. The antibody titer and specificity of the immune sera were... |
