The primary objective of this paper was to determine key factors impacting the frequency of consumer visits to Texas farmers’ markets measured in number of visits per month. Data obtained from in-person surveys administered in two farmers’ markets locations were used to determine consumer, market factors, and socio-demographic characteristics of shoppers affecting frequency of visits. The results of the model showed that travel distance, number of adults in the household, market promotional characteristics such as entertainment and education activities, food events, as well as education and age were all determinants of frequency of visits to farmers’ markets. |

Because resilience of a biological system is a product of its evolutionary history, the historical template that describes the relationships between species and their dynamic habitats is an important point of reference. Habitats used by Pacific salmon have been quite variable throughout their evolutionary history, and these habitats can be characterized by four key attributes of disturbance regimes: frequency, magnitude, duration, and predictability. Over the past two centuries, major anthropogenic changes to salmon ecosystems have dramatically altered disturbance regimes that the species experience. To the extent that these disturbance regimes assume characteristics outside the range of the historical template, resilience of salmon populations might be... |

Human herpesvirus 8 (HHV-8), the etiological agent of Kaposi's sarcoma (KS), is endemic in parts of the sub-Saharan, and KS has increased concomitantly with the HIV/AIDS epidemic. In Mozambique (MZ), no data concerning HHV-8 infection was available, thus the main of this work was to investigate, for the first time, the presence of HHV-8 infection in Maputo, MZ. Latent and lytic HHV-8-specific antibodies were assessed in blood samples from 189 individuals from the Central Hospital of Maputo, MZ, using "in-house" immunofluorescence assays conducted in São Paulo, Brazil. The results obtained were analyzed according to socio-demographic and clinical variables using the Chi-square test and logistic regression. An HHV-8 seropositivity of 1.8% and 9.7% was... |

Forage supply from herbs was assessed in a thinned Caatinga enriched with buffel grass (Cenchrus ciliaris L.) exposed to goat and sheep grazing. The 2.4 ha experimental area, located at the Experimental Station of the Federal University of Campina Grande, in Santa Terezinha, Paraíba State, Brazil, was divided into four 0.6 ha paddocks, which were further subdivided into two 0.3 ha experimental plots. Twelve F1 (Boer x SRD) goats and 12 Santa Inês sheep were divided in four groups of six animals of the same species. The herbaceous vegetation was separated into buffel grass (Cenchrus ciliaris L.), dicotyledons and other grass species. Treatments were randomized to plots according to a completely random design with two treatments, four replications, with... |

The frequency of canine heartworm disease was determined in 310 dogs (158 males and 152 females) from São Paulo city (154) and several towns along the São Paulo state coast (156). The survey was carried out through the Knott's technique (direct presence of microfilariae in the blood) and ELISA for soluble circulating antigen detection. Twenty five (8.0%) samples were positive to D. immitis using both methods being 6 dogs (3.9%) from the city and 19 (12.2%) from the coastal area. Nineteen dogs (6.1%) were positive to the Knott's technique (4 from the city and 15 from the coastal area) and 12 dogs (3.9%) to the ELISA (4 from the city and 8 from the coastal area); six dogs (1.9%) were positive for both methods being two from the city and four from the coastal... |

Resumo: A pesquisa teve por objetivo avaliar os efeitos dos percentuais crescentes da remoção da fitomassa sobre os parâmetros fitossociológicos e produtivos do estrato herbáceo, de uma caatinga raleada, em um pianossolo solódico. Os tratamentos aplicados ao fim da estação das chuvas constaram de percentuais de retirada da fitomassa do estrato herbáceo, isto é: 100, 75, 50, 25, 0 e testemunha (sem corte). A cobertura do solo não foi afetada pelos tratamentos, mas variou no período experimental (P<0,01). A frequência de Aristida setfolia H.B.K. não mudou com o tempo nem sob o efeito dos tratamentos, enquanto que as de Diodia sp. e Jaquemontia ferruginea Choisy aumentaram de 1977 a 1980, sem contudo, serem afetadas pelos percentuais de remoção testados. A... |

In simple terms, a phytosociological survey is a group of ecological evaluation methods whose aim is to provide a comprehensive overview of both the composition and distribution of plant species in a given plant community. To understand the applicability of phytosociological surveys for weed science, as well as their validity, their ecological basis should be understood and the most suitable ones need to be chosen, because cultivated fields present a relatively distinct group of selecting factors when compared to natural plant communities. For weed science, the following sequence of steps is proposed as the most suitable: (1) overall infestation; (2) phytosociological tables/graphs; (3) intra-characterization by diversity; (4) inter-characterization and... |

Using typhoon data over the Northwestern Pacific (NWP) in 60 years (1950-2009), the interdecadal variations of typhoon frequency, track and intensity are statistically analyzed. The results showed that the frequency of typhoon over the NWP was high in 1960s and low in 1970s. From the late 1990s, the frequency is low again. The track of typhoon was mainly shifting, and the average track was at the southern NWP in 1960s and 1970s, but in recent 10 years, the track was at the northern NWP. The intensity of typhoon was strong in 1950s and 1960s, but becomes weak in recent 25 years. In high frequency periods of typhoon, the subtropical high of NWP was weak and its position appears easternly. The distribution of Sea Surface Temperature (SST) shows... |
