Carbon Stock and Chemical Fractionation of Organic Matter in Different Soil Management Systems in the Bahian Cerrado

ABSTRACT Determining total organic carbon and its stock and quantifying the chemical fractions of soil organic matter can be used as indicators of the quality of the soil management used in a cropping area. This study aimed to quantify soil organic matter’s carbon stock and chemical fractions in different soil management systems used in the western Bahian Cerrado, Brazil, and compare them to a native Cerrado area. Ten microregions (Alto Horizonte, Anel da Soja, Bela Vista, Cascudeiro, Coaceral, Novo Paraná, Panambi, Placas, Roda Velha, Roda Velha de Baixo), three soil management systems [tillage system (TS), no-tillage systems (nTS), native Cerrado (NC)], and two soil layers (0–0.1 and 0.1–0.2 m) were studied. Soil bulk density (Sd), soil organic matter (SOM), total organic carbon (TOC), SOM quantification (qSOM), equivalent carbon stock (EqCs), humin (HF), humic acid (HAF) and fulvic acid (FAF) fractions from SOM were evaluated. The results indicated that Sd in all evaluated microregions was below the critical upper limit that would restrict plant root development. SOM, TOC, EqCs, and qSOM revealed increasing results following the TS, nTS, and NC order. The NC area presented the highest soil organic fraction contents (HF, HAF, and FAF). The microregions with better soil quality for all evaluated parameters were Coaceral and Cascudeiro; the lowest soil quality was observed in Alto Horizonte. The present study indicates that conservation agricultural management, such as the no-tillage system, improves the structure and composition of SOM parameters over time.

Autogamy ensures reproductive success in the bromeliad Dyckia dissitiflora Schult.f., endemic to the Brazilian caatinga domain

AbstractThe genus Dyckia (Bromeliaceae) is endemic to South America, and its species show important ecological roles in xeric environments. The flowering phenology as well as floral and reproductive biology were monitored monthly in Dyckia dissitiflora at two sites (Bela Vista: 11°42′03.4″ S 39°05′21.7″ W and Barra do Vento: 11°37′58.1″ S 39°03′33.7″ W) in the municipality of Serrinha, Bahia, Brazil. Flowering occurs in the early austral summer with a peculiar time of beginning of anthesis (10:00–11:00), offering resources 18 h after the first petal movements. Pollen viability was 98%, with a high production of pollen grains. Stigma receptivity is continuous from flower opening to senescence, and nectar production initiates at 04:00 and extends until 18:00. The species is self‐compatible and autogamous, but not agamospermic. Pollen tubes developed and reached the micropyle within 24 h in all of the reproductive tests. The hummingbird Chlorostilbon lucidus was the only floral visitor and pollinator (frequency = 0.82 ± 0.02). Fruiting occurs 3 days after anthesis, and the seeds are wind‐dispersed. Self‐compatibility and autogamy are essential strategies for the reproductive success of D. dissitiflora in light of the low number and visit frequency of its pollinators, and it is favored by slow floral movements and the position of the stigmas in relation to stamens.

Anfíbios e répteis do Refúgio Biológico Bela Vista – hidrelétrica Itaipu, estado do Paraná, sul do Brasil

Abstract Information regarding species occurrence is fundamental to understanding biodiversity distribution. However, the biodiversity from the west of the state of Paraná has been historically less studied, especially amphibians and reptiles. For this reason, we present the first reptile list of species from the west of the state of Paraná and extend the current list of anurans for the municipality of Foz do Iguaçu. The species list was based on a systematic field study conducted at Refúgio Biológico Bela Vista (RBV) a conservation area within the Hydroelectric Power Itaipu Binacional. We integrated the species list with previous species observations available in the literature for the same place where our sampling was conducted. A total of 41 species of amphibians and reptiles are presented. All amphibians species found were recorded in the field; however, from the 22 species of reptiles recorded, three were historical records obtained before this study. Species were all classified as Least Concern and/or had stable populational status according to the IUCN. Sampling sufficiency was achieved for anurans but not for reptiles, probably due to low abundance of several snake species. The most abundant species of anuran was Dendropsophus nanus, from the Hylidae family, whereas Leptodactylus plaumanni and Scinax squalirostris were represented by only one individual each. The lizard Salvator merianae was the most abundant reptile, and seven species were represented by only one individual each. The most successful sampling method for adult anurans was active search in water bodies whereas most of reptile species were observed by accidental encounters and not through a systematic sampling method. We found that herpetofauna composition from RBV was similar to other communities from Paraná state that also occur within the Semideciduous Seasonal Forest. Finally, as additional information to the species list, we offer species identification keys and discuss the importance of Refúgio Biológico Bela Vista to harbor the anuran and reptile diversity of the region.

Agroforestry homesteads from the perspective of the community members of the Uatumã Sustainable Development Reserve, Amazonas, Brazil

The aim of this study was to describe the main characteristics of the agroforestry homesteads of the communities Bela Vista, Maracarana, São Benedito and Manain located in the Uatumã Sustainable Development Reserve, in the state of Amazonas, Brazil. A total of 55 homesteads were randomly selected and characterized in the four communities where semi-structured interviews and guided tours were conducted with the residents to collect socioeconomic information and information regarding the contribution of these agroecosystems to the community. The management of the homesteads is simple and low cost, since it involves traditional practices of plant cultivation and the main purpose of the homesteads in the Maracarana and Manain communities is to provide food supplies for family units, and sale of their production at markets. Thus, it can be stated that the agroforestry homesteads of the communities of the Uatumã Sustainable Development Reserve are a production system for consumption by the family and for income, which contribute to the food security of the local population, help improve the productive capacity of the land and favor the protection of the environment, but have variable dimensions and understandings, which can change according to the family, and may eventually enter the surrounding forest.

Registro de libélulas (Odonata) predadas por aranhas (Araneae) na Mata Atlântica, no Sul do Brasil

Dragonflies are insects that act as predators and prey, both in freshwater and associated terrestrial ecosystems, which makes the understanding of trophic relationships established by these insects important. In this sense, the present study aimed to report the predation of Odonata by Araneae in areas of seasonal semideciduous forest, phytophysiognomy of the Atlantic Forest at the Iguaçu National Park (PARNA Iguaçu), and in the Bela Vista Biological Refuge (RBBV). The records occurred at random in 2021 from December 13 to 21, and in 2022 from January 4 to April 22. Five individuals of three species and two morphospecies of Odonata preyed upon by three morphospecies of spiders were recorded. Predation of Odonata by spiders seems to be frequent in different ecosystems, but further studies are required to understand the impact of this predation on the size of dragonfly communities in the Brazilian Atlantic Forest biome.

INFLUENCE OF METEOROLOGICAL VARIABLES AND GEOGRAPHIC FACTORS IN THE SELECTION OF SOYBEAN LINES

This study aimed to evaluate the influence of meteorological variables and geographic factors on the selection of soybean lines concerning grain yield in Brazil and Paraguay soybean-producing regions. The study was conducted in seven different environments: Bela Vista do Norte - PY, Palotina - PR, Mangueirinha - PR, Major Vieira - SC, Três Passos - RS, Toledo – PR, and Passo Fundo - RS. The randomized block design in an incomplete factorial scheme with six soybean genotypes (G1, G2, G3, G4, G5, and G6) was used for the experiments. The harvest occurred in the first half of March, and grain yield was measured through the total harvest of the plot and expressed in kg ha-1, with grain moisture at 13%. The climatic variables used in the study were maximum air temperature (Tmax, ºC), average air temperature (Tavg, ºC), minimum air temperature (Tmin, ºC), relative air humidity (RH, %), precipitation (Prec, mm), wind speed (WS, m/s), dew point (DP, °C), incident radiation (Rad_Inc, MJ/m²), and total radiation (RAD_OL, MJ/m²); and geographic factors were altitude (ALT), longitude (LON), and latitude (LAT). The G5 genotype with a genetic value for grain yield above the general average is the most adapted to favorable environments. Altitude had the greatest influence on the biological variability of the genotypes, with a negative correlation of moderate magnitude with grain yield. Grain yield was enhanced in environments with altitudes lower than 338 m at latitudes below 24.17S.

Análises de adaptabilidade e estabilidade da soja ao sistema orgânico por meio de metodologias AMMI, GGE Biplot e modelos mistos

ABSTRACT: This research determined the adaptability and stability of soybean yield for organic systems in different environments. Grain yield data (GY, kg ha-1) from experiments with six soybean genotypes evaluated in six environments in Brazil and one environment in Paraguay were used. The experimental design used was randomized blocks, organized in an incomplete factorial scheme, with six environments in Brazil (Toledo- PR, Palotina- PR, Mangueirinha- PR, Três Passos- RS, Passo Fundo- RS, Major Vieira- SC) and one in Paraguay (Bela Vista do Norte- PY) with six soybean genotypes (BRS 284, BRS 391, BRS 511, BRS 523, BRS 525, BRS 535) arranged in four replications per environment. BRS 511 genotype was characterized by high average grain yield and stability by the AMMI method. BRS 284 genotype was identified as the ideal genotype in the GGE biplot method. WAASBY and BLUP index selected BRS511 and BRS284 genotypes.

Opiliofauna (ARACHNIDA: OPILIONES) of the Atlantic Forest in the state of Paraná, Brazil.

Opiliones are arachnids that provide different services in terrestrial ecosystems, especially in tropical forests, which justifies inventory studies to better understand the occurrence and distribution of these arthropods in Brazil, since little is known about the harvestmen fauna in Conservation Units such as in the state of Paraná. In this context, the objective of the present study was to survey the harvestmen fauna at the Iguaçu National Park (PARNA) and in the Bela Vista Biological Refuge (BVBR), from September 2021 to May 2022, using a sampling effort of 40 hours in the BVBR, and 66 hours at the PARNA Iguaçu. Ten species/morphospecies were recorded, highlighting a new occurrence for Brazil, the species Opisthoplatus vegetus. The present study reduces the information gap about Opiliones in the state, which reaffirms the importance of Conservation Units for the protection of the biota in the state of Paraná.

Variability of Volatile Oils Composition, Tannins, and Phenols from Campomanesia adamantium (CAMBESS.) O. Berg

Campomanesia adamantium (Myrtaceae), known as "guabiroba-do-campo", is a native Cerrado shrub popularly used as anti-inflammatory, antidiarrheal, urinary tract antiseptics. The aims of this study were evaluate the seasonal variability of total phenols and tannins and chemical compounds of the volatile oils of C. adamantium leaves in a period of 12 months. The leaves and flowers were collected in Bela Vista, Goiás, Brazil. The volatile oils were obtained by hydrodistillation in a Clevenger apparatus and analyzed by GC/MS. The determination of total phenols and tannins was performed by the method of Hagerman and Butler. The major compounds of the leaves oils were γ-elemene, limonene, italicene epoxide, β-funebrene, bicyclogermacrene, linalool, and those of flower oil were sabinene, limonene, linalool, tricyclene and methyl salicylate. The total phenols content ranged from 3.75% to 9.56% and tannins content from 2.25% to 4.84%. It was concluded that the best period for collecting the leaves with the highest index phenols and tannins is the low rainfall. This work represents the first description of the seasonal variability of the essential oils, tannins and total phenols of C. adamantium collected in Bela Vista.

Agronomic Efficiency and Phosphate Solubilization of Pseudomonas fluorescens and Bradyrhizobium japonicum in Leaf-Spray Inoculation and Seed Treatment in Soybean

The use of plant growth promoting bacteria (PGPB) that can solubilize phosphorus (P) has shown potential to improve nutrient availability in many crops such as soybean. This research aimed to evaluate agronomic efficiency and phosphorus solubilization through Bradyrhizobium japonicum and product to be registered Pseudomonas fluorescens (BR 14810) in soybean, at seed and leaf-spray inoculation. Four experiments with soybean (2020/21 crop) were installed in the following locations in the State of Goiás: Experimental Area of the Goiano Federal Institute, in Rio Verde, Bela Vista Farm, in Indiara, Bauzinho Farm, in Rio Verde, and Cachoeira Farm, in Doverlândia. The B. japonicum was inoculated in the seed of all treatments. It was tested three phosphate fertilization doses: 0, 50, and 100% recommended P dose, with and without P. fluorescens, at seed treatment and leaf-spray inoculation. The use of inoculation with P. fluorescens and B. japonicum increases nitrogen (N) content in grains and total N. The P content in dry mass, grains and total are increased using P. fluorescens and B. japonicum, confirming the ability to solubilize phosphates. Inoculation with P. fluorescens and B. japonicum is efficient for increasing shoot dry mass and productivity, can be used as a sustainable soybean management technology. Leaf-spray was more efficient than inoculation in seed treatment and can be used as an alternative mode of application. The results demonstrated that the product under test (P. fluorescens-BR 14810) can be used associated with B. japonicum, in ST or leaf-spray, resulting in increases of agronomic parameters and soybean yield.

Parasitological and molecular identification of Trypanosoma species circulating in cattle and tsetse flies in Matutuine District, Maputo Province, Mozambique

Tsetse flies (Diptera: Glossinidae) are haematophagous insects of medical and veterinary importance due to their role in the transmission of trypanosomes. Tsetse-transmitted trypanosomosis is one of the major constraints to agriculture and livestock development in sub-Saharan Africa. Thus, the importance of the assessment of the distribution of both disease and vector in areas where cattle are kept, as is the case of Matutuíne district, where the last longitudinal study was conducted in 2000. From March 2009 to December 2012, 2427 bovine blood samples were collected in five administrative areas of Matutine district (Bela Vista, Zitundo, Catuane, Catembe and Machangulo). For each animal, the packed cell volume (PCV) was determined and blood examined for the presence of motile trypanosomes using microscopy. At the same time, tsetse flies were also captured. Additionally, DNA was extracted from both cattle blood and tsetse flies. The samples were further analysed using the 18S PCR–RFLP. Trypanosome infections in bovines were detected in all Matutuíne´s administrative areas. The overall prevalence of trypanosome infections was 15.62% by buffy coat and 47.34% by molecular testing. A total of 1379 tsetse flies (1379 Glossina brevipalpis and 150 G. austeni) were captured. From this, 408 were analysed by 18S PCR for the presence of trypanosomes. The results showed a percentage of infection of 12.74% and 3.19% for G. brevipalpis and G. austeni, respectively. With these results, it is concluded that tsetse-transmitted trypanosomosis is a major threat to cattle in Matutuine and control actions need to be implemented.

Environmental stratification in trials of unbalanced multiyear soybean (Glycine max (l.) Merril) via the integration of GGE Biplot graphs and networks of environmental similarity

Genotype × environment (GE) interaction can difficult soybean breeding programs to achieve the aim of more productive cultivars. Environment stratification is a way to circumvent this problem. However, multiyear data studies are difficult to work with, because they are, usually, unbalanced. GGE Biplot is an efficient method to find mega-environments, however, it allows for, at most, 30% of the unbalanced data. Thinking about how we could resolve this problem we came up with the idea of test a method that englobes GGE Biplot graphs, environment coincidence matrices and networks of environment. Wherefore, this work aimed to gather GGE Biplot graphs of a network of trials unbalance multiyear soybean via matrices of coincidence and networks of environment to optimize environmental stratification. Data from an experimental network of 43 trials was used, these experiments were implanted in 23 municipalities during the crop seasons of 2011/2012, 2012/2013, 2013/2014 and 2015/2016 in Brazil. The trials were implanted under an experimental block design with randomized treatments and approximately 30 genotypes were evaluated, of which most of these genotypes were not repeated between the trials evaluated. The GE interaction were statistically significant for all 43 trials. The step by step of our analyses was: GGE Biplots graphs were obtained; the environment coincidence matrices were calculated; the values of matrices were used to obtain the networks of environmental similarity. The study demonstrated that by the method was possible to identify, using unbalanced multiyear data, four mega-environments. The region under study can be represented by the municipalities of Palotina, Maracaju, Bela Vista do Paraíso and Rolândia. Therefore, integrating GGE Biplot graphs and networks of environmental similarity is an efficient method to optimize a soybean program by environment stratification.

Participatory Methods: the Exemplary Case of the Bela Vista “Island” in Porto (2013-2017)

The authors summarize the origin and evolution of the urban “island” of BelaVista in Porto, Portugal, since the 19th century. Despite local residents mobilizing in the wake of the revolution of April 25th 1974 in the context of the urban housing and design initiative (Local Ambulatory Support Service — Serviço de Apoio Ambulatório Local, SAAL), they were unable to renovate the crumbling neighbourhood. The Residents’ Association, resisting the onslaught of demolition strategies that were driven by real estate interests, eventually managed, with the support from a technical team of architects, social scientists and activists, to mobilize residents and ensure the political commitment of an independent parliamentary candidate in order to rehabilitate the “island” of Bela Vista. The project was also subsequently supported by the Councillors of Culture and Urbanism. Though various quantitative (survey) and qualitative (interviews, life stories) methods were applied in the study, the article highlights and expands on the action-research method opposite to positivist assumptions.

Diversity of anura amphibians in an anthropic lake in the state of Paraíba, Brazil: distribution and temporal variation

The Caatinga is highly heterogeneous, many species being found in their regions. Much of anurofauna this area is commonly found in many open environments. In the present study both the diversity and the temporal occurrence of frogs were determined to Bela Vista Lagoon, located in the municipality of Cuité, Paraíba. 4 areas for sampling were marked, these being covered slowly by hiking. The naturalistic observations were conducted from May 2012 until April 2013 Methods of visual and auditory search were used to simultaneously capture and frequency of species. 6 frog species belonging to 4 genera were found distributed in three families: Bufonidae (2 species), Hylidae (2 species) and Leptodactylidae (2 species). Site 1 showed a wealth of three species, the other areas had a wealth equivalent of 5 species each. The anurofauna recorded high occupancy presented to water bodies and low associations zones altered by man. Nonparametric estimators, calculated for the 36 surveys for the pond Bela Vista, not reached its asymptote, but the Bootstrap model showed a tendency toward stabilization. Among the four sampled areas, Area 2 was the one with the highest diversity, areas 3 and 4 presented the lowest diversity, this fact being related to high dominance of species Rinnella jimi. Regarding the temporal distribution, amphibians showed up influenced by temperature and rainfall record for the region.

LITs are classified as a “class 3 of intimal tear” and represented by intimomedial tears with an eccentric aortic wall bulge but without substantial hematoma (2). While the edges of an LIT can be undermined to a variable degree and filled with small amounts of blood or clot, there is no propagation of the dissection plane along the aorta and no exit tear and double-barrel flow channel as in classic aortic dissection (1,3). LITs may evade identification at transesophageal echocardiography or CT because of the limited extent of undermined intimal layers and a minimal amount of blood in the dissected aortic wall. This imaging pitfall can result in progression of dissection, cardiac tamponade, or aortic rupture causing potentially lethal outcomes (1,2,4). Furthermore, the diagnosis of LITs may be missed if conventional diagnostic criteria that are dependent on the presence of an intimal flap are applied (4). Awareness of this entity, high index of suspicion at CT angiography with use of appropriate reconstruction techniques for the aortic root may allow timely patient management (1) (Figure).Images in a 62-year-old man who presented to the emergency department with acute chest pain.

ECONOMIC PLURALISM AND THE PROCESS OF ENTREPRENEURIAL PLURALISM IN COMMUNITARIAN TOURISM ACTIVITIES DEVELOPED BY THE BELA VISTA DO JARAQUI COMMUNITY - MANAUS - AM

This study seeks to contribute to discussions related to other economic and entrepreneurial realities existing in Brazil, excluded because they do not fit the globalizing reality, but which contribute, in a way, to the improvement of life in lower social classes, adding in sociocultural aspects, feeding both collective labor forces and the formal economy of many capitalist companies, in which tourism is also inserted. That said, the aim of this article proposes to verify the entrepreneurial pluralism based on the economic pluralism of Zaoual (2006), identifying different entrepreneurial forms related to communitarian tourism developed in the Bela Vista do Jaraqui community, in Manaus-Amazonas. From the perspective of the dialectic of qualitative approach, we conducted field and participant research with the community with the intention of interviewing and observing the entrepreneurial practices related to communitarian tourism. The results point to the presence of entrepreneurial forms, which appear as: Bezamat's turner entrepreneurship (2017), Zaoual's situated entrepreneurship (2006), and Mandrysz's social entrepreneurship (2020). In addition, the studies found some weaknesses in relation to community and institutional arrangements.

Young people between the rural and the urban: the case of the agroboys and agrogirls in Bela Vista de Goiás

The text undertakes an analysis of young people in their rural contexts from the perspective of understanding how this social group, whether of urban or rural origin, experiences the cultural aspects of the rural universe in Bela Vista de Goiás, a town with an agricultural-based economy. The young people studied are characterized, due to their modernized way of dressing, as “agroboys” and “agrogirls”, having been influenced by the North American country and western style, by agribusiness and by the Brazilian cultural industry, thereby evidencing their existence between the rural-urban and the countryside-city. Certain conceptions of the studied group, all high school students, were identified, regarding the countryside and the city, their relationship with work, their origins, leisure practices and professional perspectives. It was concluded that these young people are living the logic of modernity and the ideal of a globalized world, with a predominant denial of the peasant project, which is linked to representations of the caipira – a yokel, of being backward, and to the production of a modernized way of living the rural.

A saber, a ética, educacional e financeira.

BEHAVIORAL ASSUMPTIONS AND ATTRIBUTES OF TRANSACTION IN THE DAIRY PRODUCTION CHAIN IN GOIÁS STATE, BRAZIL

The present study aims to analyze the behavioral assumptions of agents of the dairy chain and to identify the influences that such behaviors have on transaction costs, taking into account the relationship between the Mixed Farming Cooperative of Bela Vista de Goias (Cooperbelgo) and its members. Attributes of transactions and market governance structure present in the dairy production chain are also described, taking into consideration the study region that is the municipality of Bela Vista de Goias, Goias state, Brazil, based in the principles of the New Institutional Economics (NIE). The study was done through exploratory and descriptive research, based on the case study, using statistical data, documents, and literature review. It was mainly observed that behavioral assumptions and transaction attributes do not increase the amount of transaction costs in the dairy chain since the relations between cooperative and its members are characterized by high frequency, reliability, loyalty, and scarce presence of opportunistic behaviors and uncertainties. As a case study, results may not be simply extrapolated to other different realities. As a case study, results may not be simply extrapolated to other different realities but are useful to exemplify how the behavioral assumptions and the attributes of transactions may influence the magnitude of transaction cost in a real agri-food chain. Cooperative arrangements create trust among agents, reducing the risk for transaction cost promoting behaviors such as opportunism. Provides information about one of the most growing dairy regions in Brazil.
