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.

ABSTRACT The objectives of this study were to morphologically characterize fruits of the babassu palm tree (Attalea vitrivir) and to estimate their productivity in the north of Minas Gerais State, Brazil. Twenty mature fruits were collected from 10 plants in three different areas in Januária, Minas Gerais. Eighteen biometric parameters of the fruits were measured, the oil contents of the seeds was determined, the adherence to normal distribution was evaluated, distribution frequencies were evaluated and the effects of individuals and areas on the variables and the correlations between them were analyzed. The production of fruit bunches per plant and the number of fruits per bunch from 10 plants were quantified in three areas and the potential production under both natural harvesting and cultivation conditions were estimated. Significant differences were found among all of the biometric parameters examined between the different individuals and the different areas, which shows wide morphological variability in the fruits. The average oil content was 45.7%, but with significant differences among individuals. The observed variability favors the selection of productive individuals in genetic improvement programs. The potential productivity of endocarps and oil based on a density of 400/plants per hectare would be respectively 6.4 and 1.2 tons/ha, which indicates the possibility of using A. vitrivir for producing charcoal, bio fuels, and for carbon fixation.

Scinax comprises more than 120 species which are split in two clades, the S. ruber and the S. catharinae clades. A few species within the S. catharinae clade occur in gallery forests of the Brazilian Cerrado. We here extend the distribution of S. centralis southwards based on new populations sampled in the banks of the Rio Paranaíba, in the borders of Minas Gerais (MG) and Goiás (GO) states, southeastern Brazil. We also provide further data on the species vocalization. Variation was seen among our population and topotypes regarding SVL and call dominant frequency, both likely representing a clinal variation. Our new population of S. centralis represents the first record of the species for the state of 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.

The Lesser Bulldog Bat, Noctilio albiventris, is found in all major Brazilian phytogeographic domains. We extend the known distribution of this species in the Cerrado, where 3 specimens were collected in the municipality of Caxias, which is within the Cerrado domain of the state of Maranhão, northeastern Brazil. Our analysis of the COI gene confirms the morphological identification of the specimens, based on a 99.8–100% similarity with known sequences. This record extends the known distribution of N. albiventris 260 km to the east, in the state of Maranhão, and 986 km to the north, in the Cerrado biome.

A cladistic analysis of the genus Atlantodesmus Hoffman, 2000 is presented. With a total of 11 taxa and 30 morphological characters, and under implied weighting (k = 3), two equally most parsimonious trees (length = 58 steps; total fit = 23.150; CI = 0.64; RI = 0.64) recovered the monophyly of the genus. The resulting synapomorphies are: absence of a ventral projection on the post-gonopodal sternites; presence of folds on the dorsal edge of the prefemoral region of the gonopod; and one homoplastic transformation: presence of a cingulum. In addition, Atlantodesmus sierwaldae sp. nov. is described from the state of Minas Gerais, in the Brazilian Cerrado, and a key to the males of the genus is provided.

Domingos da Costa Lopes, nº 780, Jardim Itaipu, 17602-496, Tupã, São Paulo, Brasil, [email protected].     1 RESUMO   Minas Gerais é o terceiro estado brasileiro com maior área irrigada, sendo assim é de suma importância o manejo da irrigação para garantir o uso sustentável dos recursos hídricos. 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.

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.
