Densidade, tamanho populacional e conserva??o de primatas em fragmento de Mata Atlantica no sul do Estado de Minas Gerais, Brasil
Costa, Maurício Djalles;Fernandes, Fernando Afonso Bonillo;Hilário, Renato Richard;Gon?alves, Aline Vaz;Souza, Janaína Maria de;
Iheringia. Série Zoologia , 2012, DOI: 10.1590/S0073-47212012000100001
Abstract: the purpose of this work is to estimate the density and the population size of four primate species [alouatta clamitans cabrera, 1940; callicebus nigrifrons (spix, 1823); callithrix aurita (é. geoffroy, 1812); cebus nigritus (goldfuss, 1809)] which occur in a fragment of atlantic forest of approximately 350 hectares located in pouso alegre, state of minas gerais, as well as to give subsidies for the conservation of those species in the area. the population surveying was carried out through the distance sampling method in linear transects (distance sampling). data were collected between april and august 2008 from four transects deployed in the study area. the density and population size were calculated using the software distance 5.0 and were estimated in 23,83 ± 9,78 ind./km2 for callicebus nigrifrons, 14,76 ± 5,92 ind./km2 for callithrix aurita and 7,71 ± 2,13 ind./km2 for cebus nigritus. the population size was estimated in 83,0 ± 34,0 individuals for c. nigrifrons, 52,0 ± 20,8 individuals for callithrix aurita and 27,0 ± 7,4 individuals for cebus nigritus. with regard to the howler monkey (a. clamitans), it was stated out that just a group with six individuals survive in the area. in conclusion, the chances for these isolated populations to survive are slim due to the risk of stochastic events. the creation of ecological corridors connecting the study area to the other fragments, besides the translocation of individuals from other areas of the atlantic forest to this region, could provide alternatives to ensure the viability of these populations in a long-term. therefore, it is necessary to consolidate public policies in pouso alegre that lead to the creation, enlargement and management of conservation units and incentives for the adoption of productive practices based on sustainability in these areas of ecological interest.

Pereira, Maurício Fernandes;
Revista de Administra??o de Empresas , 2000, DOI: 10.1590/S0034-75902000000300009
Abstract: the main purpose of this article is to verify how the process of strategic change happened in a hospital organization. an empiric analysis of the strategic changes that occurred in cbs hospital in the last 20 years is developed. the direct conditions (real environment, cognitive arena) of the sector are identified as perceived environment and the network of collaborators that support the hospital's activities is determined.the period of major transformation was from 1991 to 1995, and the main changes were in the hospital culture, the doctors' and staff's work philosophy, the training way of the staff, the organizational structure, the process and the technology. it was perceived that the hospital dominant coalition is affected just by external influence due to some technologic changes and that, internally, the clinic body has control over the decision making process.

Fernandes, Maurício Romulo;Pimenta, Alexandre Dias;
Zoologia (Curitiba) , 2011, DOI: 10.1590/S1984-46702011000600016
Abstract: the taxonomy of the species of metaxia monterosato, 1884 from brazil is revised. previously to this study, only metaxia excelsa faber & moolenbeek, 1991 was known to occur in this country, under its older name metaxia exilis (c.b. adams, 1850). the review of a large amount of shells in malacological collections in brazil revealed the occurrence of three known additional species: metaxia taeniolata (dall, 1889); metaxia rugulosa (c.b. adams, 1850); metaxia prompta rolán & fernández-garcés, 2008, all previously reported from the southeast coast of the usa and/or the caribbean region. metaxia gongyloskymnus sp. nov., diagnosed by the globose protoconch with continuous axial ribs and microscopic spiral sculpture, is restricted to localities off the southeastern brazilian coast.

With the use of techniques for thematic mapping and geographical interpretation it was possible to criticize the actual configuration proposed for the metropolitan area of Londrina and suggest more objective criteria for defining it.
Urban Sprawl and the Challenges for Urban Planning  [PDF]
Maurício Polidoro, José Augusto de Lollo, Mirian Vizintim Fernandes Barros
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.39117
Abstract: Dispersed urbanization, urban planning and management instruments such as zoning, and urban expansion zones, have become increasingly consistent in leading cities toward an uncertain and chaotic future. The urban perimeters of municipalities have been used increasingly in favor agents of the reproduction of unequal urban space, aggravating the process of socio-spatial segregation, the formation of urban gaps and real estate speculation. Inherent to this process, infrastructure, one of the most important components of urban land and one of the most costly for local governments, has become increasingly dispersed and obsolete in the midst of the disordered occupation of the city’s land. Based on the above, this paper aims to analyze the phenomenon of urban sprawl in the city of Londrina by means of geotechnologies and to identify the impacts that the form of land occupation the city has employed may cause on the current and future scenario of the municipality in general. To this end, thematic maps were drawn up from multiple sources, which, allied to a review of the literature, indicate that the municipality of Londrina exhibits intense characteristics of the phenomenon of urban sprawl, leading to consequences for territorial ordering and the egalitarian spatial distribution of essential services to the population.
Influência da temperatura e da umidade relativa do ar na esporula??o de Magnaporthe grisea em trigo
Alves, Kalíbia Jane P.;Fernandes, José Maurício C.;
Fitopatologia Brasileira , 2006, DOI: 10.1590/S0100-41582006000600007
Abstract: the fungus magnaporthe grisea (anamorph pyricularia grisea) is the causal agent of wheat blast (triticum aestivum), an important disease for the wheat crop in brazil. the disease is more frequent in wheat producing regions above the parallel 24 °s. the objective of the present work was to study the effect of temperature and relative air humidity in the sporulation of m. grisea. the average number of conidia was determined in raquis of wheat plants previously colonized by the fungus and exposed to growth chambers under temperatures of 23 and 28 oc, and with relative humidity of 80, 85, 90, 95 and 100%. the number of produced conidia was determined after 24, 48, 72 and 96 hours of exposure in each combination of temperature and humidity. the effect of the temperature and the humidity was significant (p<0.001), but not the interaction. the production of conidia was also determined under natural environment conditions where temperature and the relative humidity fluctuated. the results of the present work revealed that production of conidia of m. grisea was favored by the combination of high relative humidity (> 90%) and temperature around 28 oc.
Avaliando a taxa de expans?o de les?es de Bipolaris sorokiniana em trigo
PRATES, LUCIANO GRAEFF;FERNANDES, JOSé MAURíCIO CUNHA;
Fitopatologia Brasileira , 2001, DOI: 10.1590/S0100-41582001000200012
Abstract: symptoms of spot blotch caused by bipolaris sorokiniana in wheat (triticum aestivum) first appear as small, dark lesions onthe upper side of the leaf. as the lesions expand, they become oval with a dark brown center and a yellow hallo. under favorable weather conditions, leaf lesions coalesce and kill large areas of the leaf surface. the effect of temperature on the lesion expansion rate of b. sorokiniana was examined in eight wheat cultivars. digital images of lesions of b. sorokiniana for each temperature were captured in each cultivar and stored in an electronic format. a specific computer program, called areascan, was used to measure the area of individual lesions. lesion growth ratewas not uniform among cultivars.the wheat cultivar br 18 showed the slowest lesion growth rate. the cultivars embrapa 15 and embrapa 16 showed the fastest lesion growth rates, while br 15, br 23, br 35, embrapa 40, andembrapa 49 had a moderate rate. the relationship between temperature and lesion expansion rate was described by a mathematical function, such as y=(a+bx)/(1+cx+dx2), where y is the response, x the temperature, and a,b,c, and d the parameters. nocturnal temperature of 23 oc and diurnal of 30 oc proved to be the most favorable for lesion expansion. selecting wheat cultivars with partial resistance to spot blotch is strategic for growing wheat in tropical and subtropical regions. finally, the methodological approach used in this study for determining lesion growth rate may play an important role for selecting for this genetic trait.
Efeito do tratamento de sementes com fungicida sobre o controle de doen?as na parte aérea do trigo
Picinini, Edson Clodoveu;Fernandes, José Maurício Cunha;
Fitopatologia Brasileira , 2003, DOI: 10.1590/S0100-41582003000500008
Abstract: the control of wheat (triticum aestivum) foliar diseases through seed treatment was evaluated in passo fundo, rs, during 1999. the cultivar used in the experiment was or 1 which is known to be very susceptible to powdery mildew and leaf rust. the response variables yield and test weight were significant (p>0.05) lower in the check than in the treatments. highest yields were obtained with fluquinconazol + prochloraz at rates of 250.0 g + 51.0 g (2,943 kg/ha) and 125.0 g + 25.0 g (2,864 kg/ha) being, respectively, 132% and 125% higher than the yield in check (1,270 kg/ha). while treatments with triticonazol, difenoconazol and triadimenol yielded 1,908 kg/ha, 1,821 kg/ha and 1,815 kg/ha, respectively. no phytotoxic effects due to fungicide treatments were observed. the powdery mildew and leaf rust control was effective up to 98 dae (days after emergency) which coincided with the threshold for fungicide spraying. fungicides were no longer efficient after 108 dae. powdery mildew and leaf rust severity, at 118 dae in the treatments involving fluquinconazol + prochloraz were 6.2% and 33.9%, and in the check 16.5% and 78.0%, respectively. thus, treating wheat seeds with fungicides, as demonstrated in this work, in association with crop rotations and more resistant cultivars may play an important role in controlling foliar diseases of wheat while reducing production costs and environmental polution.
