Description
An account of the resource
Background: cichlids are of economical importance either as food (Nile tilapia) or as ornamental fish (Midas) and both exhibit territorialism and aggressive feeding behavior depending on availability of food and space. Objective: to evaluate the growth rates and behavioral changes of Nile tilapia and Midas kept in mono or polyculture. Methods: Midas and tilapia were maintained in a semi-closed rearing system. Initial weight was 0.83 and 0.81 g for Nile tilapia and Midas, respectively. Four treatments with different fish proportions were used. Midas and tilapia were distributed in 12 glass aquaria with three replicates (n = 30 fish per tank). Treatment ratios between Midas and tilapia were 1:0, 1:1, 2:1 and 0:1, respectively. Fish were fed a commercial diet (40% protein, 12% lipids) for six weeks at 5% weight ratio. Feed offer was adjusted weekly. Observations of behavioral traits were recorded throughout the trial to determine social and feeding conduct. Body composition of fish was assessed at the end of the experiment. Results: Midas modified their feeding behavior and their weight gain increased (3.9 ± 0.3 g) in the 2:1 group. The 0:1 group exhibited the lowest growth rate throughout the experiment (2.9 ± 0.3 g). Midas did not affect Tilapia growth (5.8 ± 0.4 g) across treatments. Interspecies aggressiveness was less evident when reared in monoculture (groups 1:0 y 0:1). Intra and interspecies attacks were higher in the 1:1 and 2:1 groups. Proximate body composition indicated higher lipid levels in Midas across treatments in comparison to tilapia. Conclusions: duoculture benefits growth of juvenile Midas when present at 25-30% of total stocking density with Nile tilapia.

An account of the resource
The effects of salinity of the soil and water on crops can be overcome with the use of biofertilisers. The aim of this study therefore, was to evaluate the effect of salinity and bovine biofertiliser on growth, the production of essential oils, and the carbohydrate and chloride levels in plants of Plectranthus amboinicus, known locally as malvariço. The experiment was carried out in a greenhouse from March to May 2013, inplastic pots with a capacity of 7.5 L. The experimental design utilized was fully randomized in a factorial arrangement 2 x 4, with two levels of water salinity (S1= 0.7 and S2=3.1 dS m-1) and four levels of liquid bovine biofertilizer applied to the soil, corresponding to (B1=0, B2=10, B3=20 and B4=30%) the volume of the soil, with five replications. The following variables were evaluated: root, stem and leaf dry weight, and foliar levelsof carbohydrates, chlorides and essential oils. Salinity reduced the dry biomass of the roots; however, the application of biofertiliser, and the interaction between factors did not influence biometric variables, or the levels of carbohydrates or chlorides. Under all the conditions being evaluated, the essential oil of Plectranthusamboinicus showed esters, alcohols, phenols, ketones and terpenoids. = Os efeitos que a salinidade do solo e da água provocam nas culturas podem ser superados utilizandose biofertilizantes. Assim, objetivou-se com o presente estudo avaliar o efeito da salinidade e do biofertilizante bovino no crescimento, na produção de óleos essenciais e nos teores de carboidratos e cloreto de plantas de malvariço (Plectranthus amboinicus). O experimento foi conduzido em casa de vegetação no período de março a maio de 2013, em vasos plásticos com capacidade de 7,5 L. O delineamento experimental utilizado foi inteiramente casualizado, em um arranjo fatorial 2 x 4, sendo dois níveis de salinidade da água de irrigação (S1=0,7 e S2=3,1 dS m-1) e quatro níveis de biofertilizante bovino líquido aplicados ao solo, correspondendo a B1=0, B2=10, B3=20 e B4=30% do volume do solo, com cinco repetições. Foram avaliadas: massa seca da raiz, do caule e das folhas, teores foliares de carboidrato, de cloreto e de óleos essenciais. A salinidade reduziu a biomassa seca das raízes. Porém, a aplicação de biofertilizante e a interação entre os fatores não influenciaram as variáveis biométricas, os teores de carboidratos e os de cloreto. Em todas as condições avaliadas, o óleo essencial de Plectranthus amboinicus apresentou ésteres, álcoois, fenóis, cetonas e terpenóides.

Description
An account of the resource
Probiotics and co-culture of shrimp and tilapia are two strategies to improve yield and eco-efficiency of both species. However, only few studies have analyzed the combination of these two strategies. This study analyzes the effect of a mixture of potential probiotics supplied in the diet at different frequencies in a system of shrimp (10 m-2) and tilapia (5 m-2) in a trial lasting 84 days. The probiotics mixture was composed of four lactic acid bacteria and one yeast strain that were supplied either daily, every 5 days, or every 10 days in the diet and compared with a control without any supply of probiotics. At the end of the experiment, blood chemistry and hematology of shrimp and tilapia were analyzed as an index of physiological condition. Water quality did not differ between treatments. The final weight, feed conversion ratio, and yield of shrimp were significantly higher with daily supply of probiotics compared to shrimp that did not receive probiotics supply, with intermediate values for treatments with probiotics supply every 5 or 10 days. However, level of supplementation every 5 days could be considered as optimal because no significant differences with daily supply were observed for any variable, whereas the supply each 10 days resulted in a significantly lower yield. Significantly higher final weight, feed conversion ratio, and yield of tilapia occurred with daily supplements. Blood cholesterol in tilapia significantly decreased with increasing frequency of probiotics supplementation. These results indicate that probiotics supplements for shrimp and tilapia cultivated simultaneously improved yields and physiological condition.

Description
An account of the resource
Nowadays much of the chemical fertilizers used in Brazil come from imports, what creates the necessity to seek for alternative fertilizers. One possibility is organic fertilizers, including poultry litter, which presents increasing availability in various regions of the country, due to the expansion of the poultry industry. Despite its availability, there are no enough studies that show the benefits of using poultry litter on soybeans in substitution of mineral fertilizer. The present study aimed to evaluate the effect of different doses of poultry litter on leaf chlorophyll content, nodulation, and development of soybean plants. It was used a completely randomized design with five doses of poultry litter (0, 1, 2, 4 and 8 t ha-1) and a control with mineral fertilizer with four repetitions. On stages R1 and R5, chlorophyll readings were done using a portable meter and also the measurement of plant height. Plants were cut near the surface, roots were washed and the nodules were detached and counted. After that, it was determined the dry weight of plant roots, nodules, and shoots. Soybean fertilization with poultry litter increases the chlorophyll content of leaves, plant height, shoot dry matter, root dry matter, and nodulation. The use of poultry litter on soybean favors its growth with decreasing increments, except for root dry matter, and with an optimum dose for each variable. The supply of poultry litter can replace mineral fertilizers in terms of soybean growth.Atualmente, boa parte dos fertilizantes utilizados no Brasil é importada, o que cria a necessidade de busca por fertilizantes alternativos. Uma possibilidade são os fertilizantes orgânicos, incluindo a cama de aves, que apresenta crescente disponibilidade em várias regiões do país, em razão da expansão da indústria avícola. Apesar da disponibilidade e potencial, não há estudos suficientes que mostrem os benefícios do uso da cama de aves na cultura da soja em substituição ao fertilizante mineral. No presente trabalho, objetivou-se avaliar o efeito de diferentes doses de cama de aves no teor de clorofila nas folhas, nodulação e desenvolvimento de plantas de soja cultivadas em casa de vegetação. Foi utilizado um delineamento inteiramente casualizado com cinco doses de cama de aves (0, 1, 2, 4 e 8 t ha-1) e testemunha com fertilizante mineral com quatro repetições. Nos estágios R1 e R5, leituras do teor de clorofila foram realizadas com um medidor portátil bem como a medição de altura de plantas. As plantas então foram cortadas rente ao solo, as raízes lavadas e os nódulos destacados e contados. Em seguida, foi determinada a matéria seca de raízes, nódulos e da parte aérea das plantas. A adubação com cama de aves aumenta o teor de clorofila foliar, altura de plantas, matéria seca da parte aérea, matéria seca de raízes e nodulação. A utilização de cama de aves na cultura da soja favorece seu desenvolvimento com incrementos decrescentes, com uma dose ótima para cada variável. O fornecimento de cama de aves pode substituir a adubação mineral em termos de desenvolvimento da cultura da soja.

Description
An account of the resource
We evaluated the effect of the application of nutrients on the growth of Baccharis macrantha and Viburnum triphyllum, which were planted in a pasture located on the edge of an oak forest in Arcabuco (Boyacá, Colombia). The following treatments were established in plots: B. macrantha with nutrients, B. macrantha without nutrients, V. triphyllum with nutrients, and V. triphyllum without nutrients, each one with three repetitions. The phytosanitary condition, greatest and least diameter of the plant canopy, and height were measured for each planted individual. Analysis of planted species survival using the Kaplan-Meier method was performed and rates of relative growth (RGR) of height and coverage were calculated for all individuals, with which ANOVAs were performed to assess differences between treatments. The probability of survival of planted species decreased greatly over time. Significant differences between treatments were found for height and cover. According to field observation and statistical analysis, the application of nutrients considerably improved the growth in height and cover of B. macrantha, a result useful for the implementation of ecological restoration activities in pastures.

Description
An account of the resource
In vitro propagation of pineapple produces uniform and disease-free plantlets, but requires a long period of acclimatization before transplanting to the field. Quicker adaptation to the ex vitro environment and growth acceleration of pineapple plantlets are prerequisites for the production of a greater amount of vigorous, well-rooted planting material. The combination of humic acids and endophytic bacteria could be a useful technological approach to reduce the critical period of acclimatization. The aim of this study was to evaluate the initial performance of tissue-cultured pineapple variety Vitória in response to application of humic acids isolated from vermicompost and plant growth-promoting bacteria (Burkholderia spp.) during greenhouse acclimatization. The basal leaf axils were treated with humic acids while roots were immersed in bacterial medium. Humic acids and bacteria application improved shoot growth (14 and 102 %, respectively), compared with the control; the effect of the combined treatment was most pronounced (147 %). Likewise, humic acids increased root growth by 50 %, bacteria by 81 % and the combined treatment by 105 %. Inoculation was found to significantly increase the accumulation of N (115 %), P (112 %) and K (69 %) in pineapple leaves. Pineapple growth was influenced by inoculation with Burkholderia spp., and further improved in combination with humic acids, resulting in higher shoot and root biomass as well as nutrient contents (N 132 %, P 131 %, K 80 %) than in uninoculated plantlets. The stability and increased consistency of the host plant response to bacterization in the presence of humic substances indicate a promising biotechnological tool to improve growth and adaptation of pineapple plantlets to the ex vitro environment.A propagação in vitro de abacaxizeiro produz mudas uniformes e sadias, mas exige longo período de aclimatização antes da transferência para o campo. A adaptação ao ambiente ex vitro seguida da aceleração do crescimento das mudas de abacaxizeiro é um pré-requisito para a produção de maior quantidade de material propagativo vigoroso e enraizado. A combinação de ácidos húmicos e bactérias endofíticas pode ser uma tecnologia útil para reduzir o período crítico de aclimatização. O objetivo deste trabalho foi avaliar o desempenho inicial do abacaxizeiro 'Vitória' propagado por cultura de tecidos em resposta à aplicação de ácidos húmicos isolados de vermicomposto e bactérias promotoras de crescimento de plantas (Burkholderia spp.) durante a aclimatização em casa de vegetação. Os ácidos húmicos foram aplicados nas axilas das folhas basais, enquanto as raízes foram imersas no meio bacteriano. Foram observados incrementos no crescimento da parte aérea com a aplicação de ácidos húmicos (14 %) e bactérias (102 %) quando comparado ao controle, com efeito mais pronunciado no tratamento combinado (147 %). Da mesma forma, o crescimento das raízes aumentou 50 % com ácidos húmicos, 81 % com bactérias e 105 % com o tratamento combinado. A inoculação conjunta aumentou significativamente o acúmulo de N (115 %), P (112 %) e K (69 %) nas folhas do abacaxizeiro. O crescimento do abacaxizeiro foi influenciado pela inoculação com Burkholderia spp. reforçada pela associação com ácidos húmicos, que resultou em maior massa da parte aérea e raiz e maior conteúdo de nutrientes (N, 132 %; P, 131 %; K, 80 %) quando comparado com mudas não inoculadas. A consistência da resposta da planta hospedeira para bacterização na presença de substâncias húmicas aponta para uma ferramenta biotecnológica promissora para melhorar o crescimento e a adaptação de mudas de abacaxizeiro ao ambiente ex vitro.

Description
An account of the resource
Background: Ending the COVID-19 pandemic is arguably one of the most prominent challenges in recent human history. Following closely the growth dynamics of the disease is one of the pillars toward achieving that goal.Objective: We aimed at developing a simple framework to facilitate the analysis of the growth rate (cases/day) and growth acceleration (cases/day2) of COVID-19 cases in real-time.Methods: The framework was built using the Moving Regression (MR) technique and a Hidden Markov Model (HMM). The dynamics of the pandemic was initially modeled via combinations of four different growth stages: lagging (beginning of the outbreak), exponential (rapid growth), deceleration (growth decay), and stationary (near zero growth). A fifth growth behavior, namely linear growth (constant growth above zero), was further introduced to add more flexibility to the framework. An R Shiny application was developed, which can be accessed at https://theguarani.com.br/ or downloaded from https://github.com/adamtaiti/SARS-CoV-2. The framework was applied to data from the European Center for Disease Prevention and Control (ECDC), which comprised 3,722,128 cases reported worldwide as of May 8th 2020.Results: We found that the impact of public health measures on the prevalence of COVID-19 could be perceived in seemingly real-time by monitoring growth acceleration curves. Restriction to human mobility produced detectable decline in growth acceleration within 1 week, deceleration within ~2 weeks and near-stationary growth within ~6 weeks. Countries exhibiting different permutations of the five growth stages indicated that the evolution of COVID-19 prevalence is more complex and dynamic than previously appreciated.Conclusions: These results corroborate that mass social isolation is a highly effective measure against the dissemination of SARS-CoV-2, as previously suggested. Apart from the analysis of prevalence partitioned by country, the proposed framework is easily applicable to city, state, region and arbitrary territory data, serving as an asset to monitor the local behavior of COVID-19 cases.

Description
An account of the resource
Tasas de crecimiento en dos poblaciones naturales de Gasterosteus aculeatus en el noroeste de España: relación con otros parámetros vitales Se analizaron las tasas de crecimiento de dos poblaciones naturales de Galicia (noroeste de España) del pez espinoso Gasterosteus aculeatus, cuyo ciclo biológico es estrictamente anual. Para ello, se utilizó una función no lineal para conjuntos de datos de longitud por edad: el modelo de crecimiento de von Bertalanffy. Estas poblaciones europeas periféricas tienen las tasas de crecimiento más altas (k en el modelo de von Bertalanffy > 0,4 mes–1, en promedio) conocidas para esta especie. A partir de los parámetros del modelo de von Bertalanffy, se calcularon las tasas de mortalidad instantánea y de fecundidad de cada población, y se observó que las tasas de mortalidad de las poblaciones gallegas son de 2 a 2,3 veces superiores a las observadas en general en Gasterosteidae. La combinación de la fertilidad y la mortalidad produjo diferentes valores óptimos intermedios de eficacia biológica para las hembras maduras de cada población. En términos generales, estas diferencias encontradas en rasgos vitales con respecto a otras poblaciones estudiadas de pez espinoso se pueden interpretar como adaptaciones locales a un clima de tipo mediterráneo con un valor alto de grados–día. Por tanto, estas poblaciones situadas en los límites de la zona de distribución de la especie pueden estar localmente adaptadas a condiciones ambientales muy específicas y pueden ser de interés en los ámbitos de la ecología y la conservación.
