A study was undertaken about T. sordida in the natural environment in two different regions of the state of Minas Gerais: Itapagipe (Triângulo), an area of cerrado modified by the formation of fields of pasture and agriculture, and Mato Verde (north) an area of transition between caatinga and cerrado with profound deforestation in the last years due to the expansion of cotton cultivation. In both regions the principal ecotopes identified were hollow trees and the bark of live or dead trees, where the occurrence of a food source is not frequent. In this environment, the triatomines utilize various food sources; opposums appear to represent an important source of infection. In the north of Minas, a greater concentration of reservoirs and vectors was observed than in the Triángulo which could explain the higher level of infection of the triatomines in the north. Close attention to the process of domiciliation of T. sordida in the north of Minas is recommended where an extensive intervention by man in the natural environment has occurred and where a rise in the population of triatomines in the peridomestic environment has been observed in recent years.

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.

Several regions of Brazil have been experiencing periods of intense drought in the last decades. Hydropower plants produce most of the energy of the country and a reduction in the reservoir flow can compromise the energy sector. Therefore, the Brazilian government has seek the diversification of energy production with other renewable sources. The introduction of new renewable sources such as wind and solar power requires a detailed study about local weather conditions usually through historical data analysis. However, several areas in Brazil are not covered by weather stations. In this context, this study aims to assess the ability of the Global Forecast System (GFS) to represent wind, on the state of Minas Gerais (MG) which has 79.5% of energy production associated with water resources. Although the study considers a specific region, it presents a methodology that can be replicated in regions where there is no data available. For most areas, 10 meters wind speed values of the GFS analysis were similar to those registered by the weather stations. For 10 and 100 meters of altitude, results shows higher wind speed values in the north of the state, a region where the highest power densities are also recorded (approximately 150 Wm-2 in winter and spring). The state is characterized by low precipitation rates during winter and spring, when the winds are, in turn, more intense. Model results indicate that the region reaches the minimal meteorological conditions required for wind energy production that can be used as a complementary source of hydroelectricity.

Uma das formas de se calcular a quantidade hídrica necessária na irrigação é por meio da estimativa da evapotranspiração de referência (ETo). Os valores de evapotranspiração são influenciados por diversos fatores climatológicos, como: radiação solar, temperatura, deficiência de pressão de vapor, logo, os valores de evapotranspiração tendem a diferir de acordo com cada região. Assim, o presente estudo propõe a elaboração de um mapa de evapotranspiração de referência média para o estado de Minas Gerais como base para gestão hídrica para a agricultura. Os dados foram fornecidos pelo Instituto Nacional de Meteorologia (INMET), utilizando Estações Meteorológicas Automáticas (EMAs) localizadas em 49 cidades do estado de Minas Gerais. Por meio das análises realizadas, pôde-se observar que, em mesorregiões caracterizadas por maior seca, como o norte do estado, os índices de evapotranspiração foram maiores do que em mesorregiões mais úmidas, que apresentam maiores níveis de precipitação, como as Regiões Centro, Sul e Triângulo Mineiro. Devido a sua característica úmida, a região do bioma Mata Atlântica obteve menores valores de ETo em relação aos biomas do Cerrado e Caatinga. Palavras-chave: gestão hídrica, manejo da irrigação, modelagem de dados.     CUNHA, A. C.; SILVA, C. O. F.; MANZIONE, R. L.; PUTTI, F. F. REFERENCE EVAPOTRANSPIRATION THROUGHOUT THE STATE OF MINAS GERAIS AS A GUIDE FOR REGIONALIZED IRRIGATION MANAGEMENT     2 ABSTRACT   Minas Gerais is the third Brazilian state with the largest irrigated area, so irrigation management is of paramount importance to ensure the sustainable use of water resources.  One way of calculating the water quantity needed for irrigation is by estimating reference evapotranspiration (ETo). Evapotranspiration values are influenced by several climatological factors, such as solar radiation, temperature, vapor pressure deficiency; therefore, evapotranspiration values tend to differ according to each region. Thus, this study proposes the use of a medium reference evapotranspiration map of Minas Gerais as a basis for water management in agriculture. The data were provided by the National Institute of Meteorology (INMET), using Automatic Meteorological Stations (EMAs) located in 49 cities in the state of Minas Gerais. Through the analysis conducted, it was observed that, in mesoregions characterized by greater drought, such as the north of the state, evapotranspiration rates were higher than in more humid mesoregions, which present higher levels of precipitation, such as the Central, Southern, and Mineiro Triangle Regions. Due to its humid characteristic, the region of the Atlantic Forest biome had lower ETo values compared to the Cerrado and Caatinga biomes.   Keywords: water management, irrigation management, data modeling.

This chapter examines how conceptions of the environment and the state of the natural world are implicated in people's ideas about parenthood, fertility, and future generations. It carries the theme of the stable environment out into the wider world by considering what it means to care about stabilizing the natural environment in the interest of future generations. It also discusses the importance of reproduction—in humans and other parts of the natural world—in caring for the environment and working to prevent climate change. The chapter analyzes the concerns that the people of Spey Bay had about humans putting ourselves at risk of endangerment by destroying our natural environments and becoming overreliant on technology to create children. Finally, it looks at the salience of nature and naturalness to how people in Spey Bay think about reproduction, ethics, the future, and the environment.
