The objective of this work was to evaluate the flammability of ornamental species as a tool for fire management in areas of wildland-urban interface in Paraná. For this, native ornamental species and exotic species were selected. Initially, the following morphological characteristics of the leaves, which are associated with the flammability of the selected species were evaluated: texture, exudates, hairiness and enervation. The flammability characteristics of the species were analyzed through burning experiments. Fifty 1g burns of freshly harvested plant material of each species were conducted in an epiradiator. The variables collected were: ignition frequency (FI), time to ignition (TI), combustion duration (DC) and combustion index (CI). These variables were statistically analyzed by the SNK test at 95% probability. The Cluster test was also performed to identify different levels of flammability of the species tested as a function of the morphological characteristics and the flammability parameters obtained in the epiradiator tests. The results showed that FI and TI were lower in most native species (except Verbena rigida ), differing statistically from exotic ones. There were differences among the species as a function of the species leaf morphology and the flammability parameters measured during the burning. It can be inferred that most native species may have been considered slightly flammable and exotic as flammable, with the exception of the species Euonymus japonica , classified as zero flammability, concluding that native species are the most suitable for use in fire management in wildland-urban interface areas in Paraná, and should be intensively used in landscaping.

We aimed to investigate what broiler chickens prefer when given free choice between a barn side with artificial lighting only as opposed to the other barn side with natural light through glass windows and artificial light. Eighty-five 1 day-old male Cobb 500 broiler chickens were divided into 10 pens; half of each pen area was provided with only artificial light (OAL) and the other half with natural and artificial light (NAL), and birds were free to move across sides. Environmental indicators and external conditions such as temperature, relative humidity, air velocity, ammonia and illuminance were monitored inside and outside the barn. Chickens’ preference was registered each three days, divided in categories: I (at 9, 12, and 15 days), II (at 18, 21, 24, and 27 days), and III (at 30, 33 and 36 days). The effect of the interaction between environmental indicators and week was statistically different only for illuminance. Chickens preferred NAL to OAL from 18 days onwards (II p < 0.001; III p = 0.016). Drinking (p = 0.034) and exploration or locomotion (p = 0.042) behaviours were more frequent, and “not visible” behaviours (p < 0.001) were less frequent, in NAL. Foraging was the only behaviour with an interaction effect between age category and light treatment, as birds during period II expressed this behaviour more frequently in NAL than OAL (p = 0.003). For our experimental conditions, the chickens preferred NAL from 18 days of age onwards, when the confounding effect of the heating light was removed, and their behavioural repertoire was also different according to each side of the barn and to their ages.

Achyrocline satureioides (Lam.) DC is a plant in the Asteraceae family that is commonly known as macela or marcela. It has antidiarrheal, antispasmodic, analgesic, anti-inflammatory and antimicrobial properties. The species Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli are of great clinical importance, thus more evidence on the discovery of new compounds from plant species is required. The aim of this study was to evaluate the phytochemical profile and in vitro antimicrobial potential of essential oils from A. satureioides. A Minimal Inhibitory Concentration (MIC) test was performed using microdilution, and the chemical composition of the essential oil was analyzed using Gas Chromatography coupled to Mass spectrometry (GC / MS). Using the GC / MS analysis, we identified alpha-pinene and (E)-cariophilene as major phytoconstituents. We observed synergisms when the essential oil was combined with gentamicin and ampicillin against the S. aureus strain, as well as against E. coli when combined with gentamicin and norfloxacin. The results were promising, but further research is needed to assess the toxicity of A. satureioides oil and its potential for therapeutic use in humans.

The objective of this study was to evaluate the use of volumetric models, through the application of identity tests, in seven Annual Production Units (APUs) of the Tapajos National Forest (TNF), as well as to verify the precision of equations adjusted by APU volume data from the previous year for use in the following year. A total sample size of 2 100 stems were used for the adjustment of six models, and then the selected model was adjusted for the APU stratified data. The identity test, which compares adjusted equations using different datasets to verify whether or not a single equation could be used for all cases, was used to compare equations on various combinations of APUs, and a t-test was employed for validation of equations adjusted by APU data from the previous year. The identity test was significant for most comparisons, including the combinations of all the APUs, indicating that the use of one generic equation is not recommended for the entire management area. The t-test showed that there was a difference, for the majority of cases, between the observed and estimated volumes using the equation adjusted for the previous APU data. Therefore, the use of one general equation as well as equations adjusted based on data from APUs managed in the previous year is not recommended for volume estimation in TNF.

O objetivo deste estudo foi avaliar, por meio do teste de identidade, o uso de modelos volumétricos em sete Unidades de Produção Anual (UPAs) na Floresta Nacional do Tapajós (FNT), assim como verificar a validade de equações ajustadas com dados de cubagem da UPA do ano anterior para utilização na UPA subsequente. Utilizou-se uma amostra total de 2.100 árvores (300 árvores por UPA) para o ajuste de seis modelos e, em seguida, o modelo selecionado foi ajustado para os dados estratificados por UPA. O teste de identidade, que compara equações ajustadas a partir de diferentes conjuntos de dados para verificar se uma única equação pode ser empregada para todos os casos, foi usado para comparar equações em várias combinações das UPAs, bem como o teste t para validação de equações ajustadas com dados da UPA do ano anterior. O teste de identidade foi significativo para a maioria dos casos testados, incluindo a combinação de todas as UPAs, indicando que não é recomendável empregar-se uma equação genérica para toda a área de manejo. Para a maioria dos casos avaliados, o teste t indicou haver diferença entre o volume observado e o volume estimado com a equação ajustada com dados da UPA do ano anterior. Portando, o uso de uma equação genérica e de equações ajustadas com base nos dados das UPAs manejadas no ano anterior não é recomendado para a estimativa de volume na FNT.

This article discusses the extent to which Global Value Chain (GVC) governance may lead to animal welfare (AW) improvement and help to alleviate animal suffering in food producing chains. Our approach relied on scrutinizing two of the most used compulsory certification templates which are enforced by major buyers to their suppliers in order to assure responsible activity in the farmed fish chain (GlobalG.A.P. certification scheme) and in the wild-captured fish chain (Marine Stewardship Council—MSC). Since fish may experience intense suffering in regular activities involved in catching, maintenance, transport and management, we analyzed whether those instruments can contribute to improve the welfare of fish. Although positive outcomes may be expected in aquaculture production, serious welfare issues regarding wild-capture fish are brought to the fore and preliminary action is proposed. We present recommendations for improving the positive impacts of such certification schemes in GVCs and argue that sustainability-driven standards (MSC) could also embrace more AW-focused criteria in order to contribute with reducing unnecessary animal suffering in the fish chain.
