Landsat 5 has produced imagery for decades that can now be viewed and manipulated in Google Earth Engine, but a general, automated way of producing a coherent time series from these images—particularly over cloudy areas in the distant past—is elusive. Here, we create a land use and land cover (LULC) time series for part of tropical Mato Grosso, Brazil, using the Bayesian Updating of Land Cover: Unsupervised (BULC-U) technique. The algorithm built backward in time from the GlobCover 2009 data set, a multi-category global LULC data set at 300 m resolution for the year 2009, combining it with Landsat time series imagery to create a land cover time series for the period 1986–2000. Despite the substantial LULC differences between the 1990s and 2009 in this area, much of the landscape remained the same: we asked whether we could harness those similarities and differences to recreate an accurate version of the earlier LULC. The GlobCover basis and the Landsat-5 images shared neither a common spatial resolution nor time frame, But BULC-U successfully combined the labels from the coarser classification with the spatial detail of Landsat. The result was an accurate fine-scale time series that quantified the expansion of deforestation in the study area, which more than doubled in size during this time. Earth Engine directly enabled the fusion of these different data sets held in its catalog: its flexible treatment of spatial resolution, rapid prototyping, and overall processing speed permitted the development and testing of this study. Many would-be users of remote sensing data are currently limited by the need to have highly specialized knowledge to create classifications of older data. The approach shown here presents fewer obstacles to participation and allows a wide audience to create their own time series of past decades. By leveraging both the varied data catalog and the processing speed of Earth Engine, this research can contribute to the rapid advances underway in multi-temporal image classification techniques. Given Earth Engine’s power and deep catalog, this research further opens up remote sensing to a rapidly growing community of researchers and managers who need to understand the long-term dynamics of terrestrial systems.

The technology of monitoring objects of solid household waste in the Moscow region using the data of space and aerial survey is considered. In order to solve the problem, we used space survey materials obtained from the Worldview-2 satellite (spatial resolution of 1,5 m per pixel) and special aerial filming performed with the help of an Azimuth-2M photo-imaging system based on a hang glider (spatial resolution not coarser than 0,1 m per pixel). On the basis of those materials, digital models of accommodation facilities for solid household wastes and orthophotoplans were obtained, using which a comparative analysis of the state of landfills was performed. The analysis was carried out according to several indicators, including the impact of polygons on the ecological state of the surrounding territories and the cluttering the surrounding territory with waste was determined. It is shown that the use of remote sensing materials enables obtaining the necessary information to monitor the state of solid waste landfills, while performing the minimum amount of field geodetic works.

Fimicolous organisms are those that can grow on dung. These substrates offer conditions that favour colonization by microorganisms, such as high nutrient and moisture content and an alkaline-neutral pH that is especially advantageous in arid/desertic regions. There are about 250 species of myxomycetes known from Brazil, which are distributed in all geographic regions and biomes, obtained mainly from plant-derived substrates. However, there are some reports of fimicolous myxomycetes in Brazil. In this study, we expand this knowledge with new records of fimicolous myxomycetes in multiple Brazilian biomes. Between 2017 and 2018, horse and cattle dung samples were collected in municipal areas in the State of Goiás (Cerrado biome): Pirenópolis, Goiás, and Porangatu; and the State of Mato Grosso (Pantanal biome): Poconé. Samples were incubated in moist chambers and monitored for four months. Myxomycetous fructifications were observed, photographed under stereo and light microscopes, and morphologically identified. Vouchers were deposited at the HUEG Herbarium. A total of five species of myxomycetes were recorded: <em>Arcyria cinerea and <em>Physarum viride (Pirenópolis), <em>P. cinereum (Goiás City), <em>P. melleum</em> (Porangatu), and <em>Perichaena corticalis</em> (Poconé). They represent the first records of fimicolous myxomycetes from the Brazilian Cerrado and Pantanal biomes. Additionally, <em>P. melleum</em> was reported as fimicolous for the first time in Brazil and the second time in the world; <em>P. corticalis</em> was reported for the first time in midwest region as well as for the first time as fimicolous in Brazil; and <em>P. viride</em> was reported for the first time as fimicolous in the world.

O estabelecimento de zonas de amortecimento tem papel fundamental para o sucesso das Unidades de Conservação (UCs), através de critérios e normas específicas. O trabalho objetivou revisar, analisar e discutir os principais critérios utilizados para a delimitação de zonas de amortecimento no estado de Mato Grosso do Sul. Foram adotados procedimentos de identificação dos critérios a partir de consultas bibliográficas aos planos de manejo das UCs e de documentos cartográficos. Os resultados indicam que os principais critérios utilizados para delimitação de zonas de amortecimento são os limites físico-geográficos de bacias hidrográficas, áreas protegidas, faixas territoriais limítrofes como rodovias, estradas e cursos d’água. Nota-se em alguns casos que a aplicação de limites genéricos, como os dispostos na Resolução CONAMA 10/93 e 428/2010, excluem áreas importantes próximas às unidades, como nascentes e fragmentos importantes de vegetação. Identifica-se a necessidade de exposição mais clara, objetiva e concisa desses critérios nos Planos de Manejo.     Buffer Zones of Conservation Units: Concepts, Legislation, and Possibilities in the State of Mato Grosso do Sul ABSTRACTThe establishment of buffer zones has a fundamental role in the success of the Conservation Units, through specific criteria and rules for its delimitation and management. This paper aims to review, analyze, and discuss the main criteria used for limitate buffer zones in Mato Grosso do Sul. We adopted procedures for identifying the criteria from bibliographic consultations to the UCs’ management plans and cartographic documents. The results indicate that the main criteria used for the delimitation are the physical and geographic limits of hydrographic basins, protected areas, and bordering territorial bands such as highways, roads, and watercourses. We noted in some cases that the application of generic limits, such as those provided for in CONAMA’s resolutions, exclude important areas close to the units, such as river springs and important vegetation fragments. We identified the need for clearer, more objective, and concise exposure of these criteria in the Management Plans.   Keywords: Conservation Units; Buffer Zones; Mato Grosso do Sul.

Abstract: The objective of this work was to evaluate the reliability of the physiological meaning of the enhanced vegetation index (EVI) data for the development of a remote sensing-based procedure to estimate soybean production prior to crop harvest. Time-series data from the moderate resolution imaging spectroradiometer (Modis) were applied to investigate the relationship between local yield fluctuations of soybean and the prevailing physically-driven conditions in the state of Mato Grosso, located in the south of the Brazilian Amazon. The developed methodology was based on the coupled model (CM). The CM provides production estimates for early January, using images from the maximum crop development period. Production estimates were validated at three different spatial scales: state, municipality, and local. At the state and municipality levels, the results obtained from the CM were compared with official agricultural statistics from Instituto Brasileiro de Geografia e Estatística and Companhia Nacional de Abastecimento, from 2001 to 2011. The coefficients of determination ranged from 0.91 to 0.98, with overall result of R2=0.96 (p≤0.01), indicating that the model adheres to official statistics. At the local level, spatially distributed data were compared with production data from 422 crop fields. The coefficient of determination (R2=0.87) confirmed the reliability of the EVI for its applicability on remote sensing-based models for soybean production forecast.

O ecoturismo é uma área do turismo de grande importância para conservação e preservação ambiental, e que é desenvolvido principalmente em Unidades de Conservação. Tais questões podem ser desenvolvidas a partir do controle de acesso de turistas e da arrecadação de taxas para ajudar a manter tais áreas protegidas. Todavia, muitas delas ainda não conseguem fazer uma gestão adequada destas Unidades de Conservação. Nesse sentido, a criação de um sistema integrado em gestão que possa coordenar e controlar as visitações nos atrativos, bem como o repasse de taxas, pode ser uma opção de instrumento de gestão, pois ainda são poucas as ferramentas que possibilitam a gestão de dados para subsidiar uma gestão integrada eficiente. Em tal contexto, o município de Bonito, no estado do Mato Grosso do Sul, se destaca no Brasil por criar um sistema de gestão integrada que auxilia na gestão dos atrativos turísticos do município, o Voucher Digital. O Parque Estadual do Jalapão (PEJ), tal qual o município de Bonito, é um destino ecoturístico brasileiro que se destaca por seus recuros naturais. Porém, há uma grande dificuldade de gestão dos atrativos do parque, devido a fatores como falta de recursos humanos, distância dos atrativos, controle de entrada de turistas, entre outros. Assim, o presente trabalho tem como objetivo verificar as implicações existentes na aplicação do Voucher digital como ferramenta de gestão integrada do ecoturismo no Parque Estadual do Jalapão. Dentro desse contexto, a metodologia aplicada neste estudo foi a de pesquisa qualitativa, com um nível exploratório e descritivo, e aplicação de entrevista com gestor do PEJ e diretor de turismo de Bonito-MS. Como resultados obtidos, temos que no PEJ o uso de um sistema integrado de gestão, nos moldes do Voucher digital, pode aperfeiçoar a qualidade do atendimento aos turistas, reduzir os impactos provocados pela atividade turística a partir do controle de capacidade de carga dos atrativos e proporcionar um ganho econômico maior para todos os envolvidos. Assim, para sua criação se faz necessário a criação de legislações específicas, um conselho de turismo, se fazer estudos de capacidade de carga nos atrativos, integrar a comunidade do entorno e melhorar as articulações institucionais. Integrated management system and echotourist destinations: Possibility of application of digital Voucher in the State Park of Jalapão (Brazil) Ecotourism is an area of ​​tourism of great importance for environmental conservation and preservation, and which is mainly developed in Conservation Units. Such issues can be developed from the access control of tourists and the collection of fees to help maintain these protected areas. However, many of them still cannot properly manage these Conservation Units. In this sense, the creation of an integrated management system that can coordinate and control the visits in the attractions, as well as the transfer of fees, can be an option of management instrument, since there are still few tools that allow the management of data for efficient integrated management. In this context, the municipality of Bonito, in the state of Mato Grosso do Sul, stands out in Brazil for creating an integrated management system which assists in the management of the tourist attractions of the municipality, the Digital Voucher. The State Park of Jalapão (PEJ), like the municipality of Bonito, is a Brazilian ecotourism destination that stands out for its natural resources. However, there is a great difficulty in managing the attractions of the park, due to factors such as lack of human resources, distance of the attractions, tourists control, among others. Thus, the present work aims to verify the implications of applying the digital Voucher as an integrated ecotourism management tool in the Jalapão State Park. Within this context, the methodology applied in this study was of a qualitative research, with an exploratory and descriptive level, and application of interview with PEJ´s manager and director of tourism of Bonito-MS. As obtained results, there is in the PEJ the use of an integrated management system, in the models of the digital Voucher, which can improve the quality of service provided to tourists, reduce the impacts caused by tourist activity through the capacity control of attractions and provide greater economic gain to everyone involved. Thus, for its creation, it is necessary to create specific legislations, a tourism council, carry out capacity studies on the loads of the attractions, integrate the nearby community and improve the institutional articulations.

This research aims to describe the ichthyological fauna in the area surrounding the Taiamã Ecological Station in the state of Mato Grosso, Brazil. Three expeditions were carried out, in September 2014, February 2015 and May/2015, in seasons ranging from the hydrological conditions of high waters (flood), low waters (drought), and decreasing waters (ebbing). During the research we sampled 3,664 individuals from six orders, 28 families and 78 species. Characiformes was the most abundant order (̴ 81 % of individuals), followed by Siluriformes (̴ 13 % of individuals), and Gymnotiformes (̴ 4 % of individuals). The most representative species were Moenkhausia dichroura (Kner, 1858), Serrapinus calliurus (Boulenger, 1900), Odontostilbe pequira (Steindachner, 1882) and Pimelodella gracilis (Valenciennes, 1840). The dry period showed the highest abundance (1,541 individuals), richness (61 species), diversity (H’ = 2.69) and equitability (J’ = 0.65). These results fill a gap concerning species composition in the Pantanal, mainly referring to data available on Conservation Unit, and its surroundings. Moreover, this research provides a database to update the checklist of fish species in a remote wetland, offering a tool for management and conservation.
