title: In vitro culture and acclimatization of Cattleya xanthina (Orchidaceae), an endangered orchid of the Brazilian Atlantic Rainforest

description: Abstract Cattleya xanthina is a Neotropical orchid endemic to the Brazilian Atlantic Rainforest, at high risk of extinction. In this paper, we investigated the effects of different culture media on C. xanthina as well as on their endogenous nitrogen status. Culture media studied: Knudson C (KC), Vacin and Went (VW), and Murashige and Skoog (MS), the latter used at two different concentration (full and half-strength; MS/2). After 180 days, plants were transferred to MS medium with different NAA and BA concentrations. In each treatment, biometric parameters were measured and the endogenous levels of photosynthetic pigments, total protein, nitrate and ammonium ions were quantified. Plants grown on KC medium had the lowest concentration of nitrogen but exhibited the greatest shoot development, production of photosynthetic pigments and total protein. Results of growth regulators showed that the highest concentration of auxin stimulated root development and the production of photosynthetic pigments, and that a higher concentration of cytokinin promoted protein synthesis and the development of shoots. Most successful acclimatization was obtained when a mixture of Sphagnum and Pinus bark was used as the substrate.

title: Agroclimatic zoning of the Brazilian state of Mato Grosso for the production of soybean seeds of early cultivars

description: Abstract: The objective of this work was to carry out the agroclimatic zoning of the Brazilian state of Mato Grosso, in order to identify the regions with the best climatic conditions for producing seeds with high quality of early soybean cultivars. For this purpose, the average monthly temperature data from 11 conventional and 34 automated meteorological stations were used. Due to the low number of stations with data temperature available, this variable was estimated using spatial regression equations, having latitude, longitude and altitude as input variables. Regions with high or low climatic risk were defined according to the average temperatures observed in January and February. The following three categories were established: favorable (≤ 24 °C); moderately favorable (24.1 to 25 °C) and slightly favorable (≥ 25.1 °C). For the material confection, map usage, and geographical data compilation, the inverse distance squared weighted interpolation method was applied. The ArcGIS system was employed to compose the thematic map, in which the best areas for producing seeds of early soybean cultivar were marked. Most of the Southeastern, and Western regions of Mato Grosso were considered to be favorable for producing high quality seeds of early soybean cultivars (average temperature ≤ 24 °C).

title: Asteraceae diversity in earthmounds in Southwestern Goias, Brazil

description: Abstract Campos de murundus or covoal (earthmounds) is one of the less floristically known phytophysiognomies of the Cerrado, in which the arboreal component is more studied than the herbaceous-subshrub components. We present a floristic survey of Asteraceae family in campo de murundus in the municipality of Jataí, state of Goias, Brazil. The collections were made using the walking method. A total of 41 species was recorded, from which 34 species are autochthonous and seven are allochthonous to the Cerrado. The species number found is higher than that registered in campo de murundu” of Araguaia State Park, and only Ayapana amygdalina and Chrysolaena obovata are common to both areas. Species common to the studied area and 14 other localities in the Cerrado are Achyrocline alata, A. satureioides, Ayapana amygdalina, Mikania officinalis, and Chromolaena laevigata. Some species are endemic and from these, two are restricted to the Cerrado, one of them is new to science. Only one of the registered species is recorded as occurring in campos de murundus in the Brazilian Cerrado checklist. This study is the first carried out for Asteraceae in campos de murundus and we hope to contribute to expanding the knowledge of species occurring in this phytophysiognomy.

title: Hypo-hyperdontia: a case report

description: The occurrence of hypodontia (absence of teeth) and hyperdontia (presence of supernumerary teeth) in the same patient is a rarely seen condition in dental practice. Early diagnosis and adequate treatment are very important when addressing this abnormality in the mixed dentition. The approach will depend on the severity of the case and the timing of diagnosis. This paper reports the case of an 11-year-old patient with absence of the permanent maxillary lateral incisors and the mandibular second premolars, with concomitant presence of a supernumerary tooth in the region of the right mandibular lateral incisor. Based on physical and radiographic examination findings, a diagnosis of hypo-hyperdontia was made. The diagnostic and therapeutic management of the case is discussed. The treatment adopted was surgical removal of the supernumerary teeth and esthetic restoration to transform the permanent mandibular canines into lateral incisors.

title: Multiple resistance to bacterial halo blight and bacterial leaf spot in Coffea spp.*

description: ABSTRACT Breeding for genetic resistance is an important method of crop disease management, due to the numerous benefits and low cost of establishment. In this study, progenies of 11 Coffea species and 16 wild C. arabica accessions were tested for their response to Pseudomonas syringae pv. garcae, the causal agent of bacterial halo blight, a widespread disease in the main coffee-producing regions of Brazil and considered a limiting factor for cultivation in pathogen-favorable areas; and also to P. syringae pv. tabaci, causal agent of bacterial leaf spot, a highly aggressive disease recently detected in Brazil. Separate experiments for each disease were carried out in a greenhouse, with artificial pathogen inoculations and ideal moisture conditions for disease development. The results showed that C. canephora, C. congensis, C. eugenioides, C. stenophylla, and C. salvatrix progenies, the wild C. arabica accessions Dilla & Alghe and Palido Viridis, and cultivar IPR 102 contain satisfactory levels of simultaneous resistance against bacterial halo blight and bacterial leaf spot. These results are useful in breeding programs for durable resistance to multiple biotic agents, providing new combinations of resistance alleles by hybridization, as well as for phytopathological studies, to identify infraspecific variability of the pathogens.

title: Spatial patterns of ferns in Evergreen Seasonal Forest in Amazonia-Cerrado transition

description: Abstract The climate and soil conditions are important predictors of spatial patterns and alpha diversity of plant populations. The spatial distribution of plant populations provides information about ecological processes that control the communities. In this study we investigated the richness and intra and interspecific spatial patterns of ferns in an Evergreen Seasonal Forest in the Amazonia-Cerrado transition. We described the spatial patterns by the univariate and bivariate O’ring function. We recorded four species of ferns samambaias (Trichomanes pinnatum, Lindsaea pallida, Adiantum incertum e Campyloneurum phyllitidis). All species exhibited the intraspecific spatial pattern aggregated. A positive interspecific pattern was observed between T. pinnatum and A. incertum, and L. pallida and A. incertum, however, we did not observe spatial relations between T. pinnatum and L. pallida. The strong climatic seasonality combined with a topographic homogeneity may be influencing the low species richness. The aggregation of these species is indicative that the dispersion limitation and the habitat structuration are determining their distribution. The species positive spatial associations may be reinforced by the environmental stress during the dry season. The absence of spatial relationships may be an indication that neutrality may partially explain the distribution of ferns in the studied forest.

title: Association between the artificial aging test and the natural storage of coffee seeds

description: Abstract: The accelerated aging test is recognized as an efficient method for evaluating the vigor of seed lots and for estimating their storage potential. Thus, this work aimed to evaluate the association between artificial aging and natural storage of coffee seeds, through the correlation factor analysis. Seeds of four cultivars of Coffea arabica L. (Catuaí Amarelo, Arara, Catiguá, and Mundo Novo) and one of Coffea canephora Pierre (Apoatã) were used. Part of the newly-harvested seeds were aged in a growth chamber under controlled temperature and relative humidity conditions (42 ºC and 100% RH) for periods of 0, 4, 6, 8, and 10 days. The other part of the seeds was stored in tri-wall paper packaging for a period of 2, 4, and 6 months in a non-climate-controlled environment. Artificial aging allows predictions on the storage potential of coffee seeds, although the artificial aging periods depend on the cultivars.

title: El urbanismo humanista y la "policía española" en el Nuevo Reino de Granada, siglo XVI

description: The European urban project established in America during the sixteenth-century deemed the city as the highest expression of civilization. This article shows the urban genealogy of the American "pueblos de indios" (Indian villages), built to concentrate the native population, and to teach them the Catholic doctrine. The urban form could be traced by comparing several architectural treatises considered "humanistic" that show the city as a medium to express a specific behavior; thus, the city was a pedagogical and emotional space to control the indigenous population. As a practice of good governance, the "pueblos de indios" materially condensed the "Spanish police" principles. Besides the humanistic background of the towns imposed in America, the project sought to homogenize the natives' behavior and beliefs.

title: Evaluability of the Social Mobilization Project for Prevention and Control of the Dengue in Bahia

description: ABSTRACT An evaluability study of the Project Social Mobilization for Dengue Prevention and Control in the State of Bahia was performed, and the practical intervention model was described. Data collection involved interviews with key informants, documentary analysis and participant observation. The results indicate that the Project can be considered implemented, and its main results are related to the change of focus on dengue in the media's agenda, as well as a greater integration of federal entities, and between the Community Health Workers and the Endemic Agents. Aspects related to the municipal context were seen as obstacles to the achievement of the expected results.

title: Physiological quality of soybean seeds produced under artificial rain in the pre-harvesting period

description: Abstract: The objective of this experiment was to evaluate responses of soybean cultivars seeds (with different levels of lignin) considering harvest postponement under the incidence of water and the effect of storage. The experiment was conducted in Iraí de Minas, Brazil using a randomized block design with three replications under a 5 x 3 x 3 factorial arrangement, with five soybean cultivars (NK 7059 RR, SYN 1163 RR, SYN 9070 RR, AS 7307 RR and SYN 1283 RR), three harvesting periods (R8, R8 + one rain simulation in the pre-harvesting period and R8 + two simulations in the pre-harvesting period) under three storage times (0, 90 and 180 days). Seeds were evaluated for their chemical composition (lignin contents), the percentage of moisture damage using the tetrazolium test and physiological quality (germination, accelerated aging, conductivity test, seedling emergence and emergence index). Cultivar AS 7307 RR had the highest lignin content in the integument, the lowest percentage of damage by moisture and the highest physiological quality. Cultivars NK 7059 RR and SYN 1163 RR had the lowest lignin contents in the integument and the highest moisture damage. Electrical conductivity increased after storing all cultivars.
