The objective of this work was to compare the leaflet severity of Asian soybean rust in farms sown in December and February in the state of Mato Grosso. In the survey, 28 fields were sampled in 14 counties in the North, West and South regions of the state. A total of 40 leaflets were collected per plot, in randomized treatments with four replication and three crop phenological stages. Leaflet severity was assessed according to a diagrammatic scale. The data were expressed as leaflet severity, submitted to linear regression analysis, calculated the area under the disease progress curve (AUDPC) considering the three phenological stages sampled, and the means compared by the Tukey’s test. Leaflet severity was significantly higher in the fields sown in December than in February, as well the number of fungicides sprayings. Our results indicate that the proposed change in seeding time from December to February can be implemented by significantly reducing risks and in compliance with the principles of IN 002/2015.

This review seeks to expand the knowledge about the epidemiology of Asian sybean rust in the state of Mato Grosso and contribute to ensuring the economic sustainability of soybean crop. It is discussed the Phakopsora pachyrhizi potential of dispersal from Asia to South America and finally to Mato Grosso state. The origin of the Asian soybean rust inoculum within Mato Grosso is addressed by the survival in volunteer and soybean weed plants (Pitelli, 2015) in other crops such as cotton. Data on the adverse environmental effect on the soybean plants survival are shown mainly the water deficit from June to August. Reports on the effect air temperature and mainly solar radiation on the mortality of airborne spores during their anemophilous spread on sunny days are also discussed. This increase of knowledge aims to make the soybean-free period more efficient by the knowledge on the soybean plants survival and on the fungus viability in the month of August. Due to the proximity of soybean farms, during the soybean-free period, in other states (Tocantins, Goiás, Rondônia, etc.) and in other neighbor countries we discuss the likelihood that inoculum in the state may also originate in out-of-state crops during the Mato Grosso soybean-free period.

ABSTRACT Evolution has been reported for the reduction in Phakopsora pachyrhizi sensitivity to the mixtures of the three site-specific mechanisms of action (DMIs, QoIs and SDHIs) used in its control. The aim of this study was to quantify the current contribution of QoIs, alone or in mixture with triazoles, in the control of Asian soybean rust. In an experiment carried out in the field, the efficacy of quinone outside inhibitors (QoIs), or strobilurins, was compared for Asian soybean rust control. The isolated effects of four doses of azoxystrobin, picoxystrobin, pyraclostrobin and trifloxystrobin were evaluated, as well as of four applications during the crop cycle. Control by commercial mixtures of these QoIs with triazoles was also compared. Severity was evaluated in four phenological stages, and control was calculated based on final severity data, area under rust progress curve, defoliation, one-thousand-grain mass, grain yield and damage caused by the disease. The lowest mean of rust control efficacy resulted from applications of azoxystrobin (15.8 and 11.19%) and pyraclostrobin (15.4 and 16.76%) and the highest mean was found for picoxystrobin (54.1 and 54.35 %) and trifloxystrobin (69.7 and 64.46%), calculated based on final severity and AUDPC, respectively. Such efficacy is not enough to cover the fungicide application cost, although there was a positive effect of treatments on disease control and grain yield.

The objective of this work was to assess the effect of December sowing time with February on the Asian soybean rust severity. In on-farm trials two soybean treatments sowing in December (2020) (DSS.) and February (2021) (FSS) were assessed for Asian soybean rust severity in 24 sites, in three regions of Mato Grosso state. The DSS treatment was established in the growers commercial farms and the FSS in a 5 ha area sown specifically for this treatment. The DSS treatment was conducted in 16 sites and the FSS in eigth. For rust control fungicides with efficacy higher than 60% were sprayed consisting of DMIs, QoIs and SDHIs in double or triple mixtures, always added by multisites (chlorothalonil, mancozeb, or copper oxychloride). About eighty soybean leaflets from four plots repetitiond, demarcated at random in each field, were taken in each smpling. In laboratory leaflet severity was appraised and area under disease progress curve (AUDPC) calculated. Related to DSS, the AUDPC overall mean was 174 units and receiving 6.9 fungicide spraying and for FSS 26 units with 4.8 fungicide sprayings. Our results reinforce that the sowing time can be changed from the end of December to February to maintain soybean crop sustainability.

AbstractThe bush dog Speothos venaticus, a rare Near Threatened South American canid that lives in packs, was thought to be extinct in Minas Gerais state, south-eastern Brazil, until recently. Here, we report four recent records of the species in Minas Gerais, the first in the state since the description of the species in 1842. All records are from the Cerrado ecosystem in the north and north-west of the state; two are from animals found dead, one from footprints and another from a camera trap. Three of the records were inside or close (< 10 km) to strict protected areas, in a region recognized as the Protected Areas Mosaic Sertão Veredas–Peruaçu, where we expect any new records of the bush dog to be found. We discuss the low probability of detecting the bush dog and the main regional threats to the species, and emphasize the need to protect large and interconnected natural areas and keep them free of domestic dogs to avoid the extinction of the bush dog in Minas Gerais.

Title in Portuguese: Funções de migração por idade e caracterização de migrantes das microrregiões de Goiás e Distrito Federal, 1975-1979 e 1986-1990(Dissertação de Mestrado)(M.A. Thesis)Since the 70’s, the Brazilian Middle-West Region has experienced an important modernization process in agricultural and industrial activities, which has led to an employment retraction and migration flows, especially from rural areas to the major metropolitan cities of the region. In this research the focus of analysis are the State of Goiás and the Federal District, which encompasses Brasília, the capital of Brazil. In order to understand the new population configuration, the region was divided into four sub-areas (micro-region of Goiânia, micro-region of Entorno de Brasília, the Federal District, and a group of 16 micro-regions of Goiás) and the patterns of migration, by age and sex, were estimated for the periods 1975-1979 and 1986-1991. In addition, differences between native and migrant population of each sub-area, according to the participation in the labor force, income, education and type of migration were investigated. The analysis was performed on the basis of the 1980 and 1991 Brazilian Census data.In the intra-state migration, the fluxes between the micro-region of Goiânia and the 16 other micro-regions of Goiás, and between the Federal District and the micro-region of Entorno de Brasília were the most important. In the inter-state migration, the flux from the states of Mato Grosso, Mato Grosso do Sul and the North region to the 16 micro-regions of Goiás, as well as the flux from Northeast, Southeast and South to the Federal District were significant. But there was a decline in the migration to the Federal District, between 1975-1979 and 1986-1991, while, in the same period, the migration to the Entorno of Brasília increased.The chance of the migrant population in the micro-region of Goiânia and in the Federal District to have worked in the last 12 months prior to census interview was lower than that of the native population. However, those who migrated from the Federal District to the micro-region of Entorno de Brasília had higher chance to have worked in the formal sector than those who did not migrate. Migrants who moved from the micro-region of Entorno de Brasília and the 16 other micro-regions of Goiás to the micro-region of Goiânia had lower wages than the non-migrant population. The lowest level of wages was recorded for the migrants to the 16 other micro-regions of Goiás. Migrants living in the Federal District had high level of education, while those migrants living in the micro-region of Entorno de Brasília had low level of education.In 1986-1990, the micro-regions of Goiânia and Entorno de Brasília, as well as the 16 other micro-regions of Goiás, presented a high percentage of returned migrants. In the same period, a major proportion of migrants to the micro-region of Entorno de Brasília had first moved from Southeast or from the Federal District to others regions. In addition, there was a considerable proportion of migrants with low income who had moved from Northeast to the Federal District and then to the micro-region of the Entorno de Brasília.Future research could focus other areas or regions of Brazil, and could also explore the same kind of analysis, on the basis of the incoming 2000 Brazilian Census, which requires the development of new techniques, as it did not collect information on the city of previous residence, but only on the state of residence.

Birds are considered one of the most well-known groups of animals in the Pantanal, playing an important ecological role in wetland ecosystems. Our aim was to identify the main themes and gaps in current knowledge of these birds, considering thirty years of scientific research to direct future studies. We performed a scientometric analysis based on five platforms with the search words “Aves” and “Pantanal” as well as “Bird” and “Pantanal”. We identified 145 scientific studies, with themes of ecology (64), conservation (23), health (17), fauna (15), genetics (12), geographic distribution (7), and environmental education (7). The number of publications has increased significantly over the years. However, the focus is predominantly on certain Pantanal regions, such as the municipalities of Corumbá in Mato Grosso do Sul state and Poconé in Mato Grosso state. Anodorhynchus hyacinthinus and Mycteria americana are among the species with the largest number of studies in the Pantanal, with 12 and 11 papers, respectively. We highlighted the need for new studies in regions such as the north-west and themes such as threatened species and ecosystem services. Integrated knowledge and interdisciplinary approaches can be useful in strategic decision-making and more effective for bird conservation in wetlands.

Introduction. Prior to detailed review of the North- West Federal District (NWFD) pulmonology service per- formance during the COVID-19 pandemic, it is especial- ly worthwhile to evaluate its human resourcing in the prepandemic period of 2015–2019, since the perfor- mance of pulmonology service largely depends on its staffing, moreover in conditions of restructuring and decreased number of pulmonology bedspace in hospi- tals. Мethods. In the course of the study, the authors have analysed human resourcing data for pulmonology profile within the state healthcare system in NWFD for the period of 2015–2019. The results were statistically processed and data analysis carried out using Micro- soft Office Excel and SPSS software. Results . In the state healthcare system medical institutions of the NWFD throughout 2015–2019, the number of regular pulm- onologists’ positions fluctuated unrhythmically. The number of pulmonologists (MDs) in NWFD grew 0.82% during the period of 2015–2019, for comparison, in the Russian Federation the growth for the same period was 32.08%. The number of operating pulmonology depart- ments remained practically the same, but the number of occupied positions constantly changed. Practically all the pulmonologists in the NWFD have a specialist certi- ficate, but the share of doctors with qualification grade remains insufficient, and is on the decrease. Statistical analysis demonstrated significant positive Pearson cor- relation between the number of pulmonologists and general respiratory incidence (0.74 р=0.04), mortality (0.756 р=0.003), and the number of occupied pulmo- nology bedspace (0.619 р=0.024). Conclusion. Today, pulmonology service human resourcing review is to be conducted taking into account respiratory morbidity and mortality and the need for pulmonology services among the general population. Currently, there is no sci- entifically justified regulatory framework for the deve- lopment of the pulmonology service in NWFD regions, while the work of such services depends very much on the regional budgets and medical services’ tariffs. The development and fast implementation of such compre- hensive measures as salaries’ increase, adequate social support, regular residential and non-residential courses of continuous medical education, professional networ- king, etc. will allow to maintain and holistically develop the human potential of the NWFD pulmonology service.
