Hylidae from Chapada dos Veadeiros, Central Brazil. A new species of the Scinax ruber clade is described from Chapada dos Veadeiros region, Central Brazil. The new species is diagnosed by having SVL The new species uses temporary creeks in rock meadows above 1. The dorsal color pattern enables this species to camouflage in this kind of surfaces.
Morphometric and bioacoustic data on three species of Pseudopaludicola Miranda-Ribeiro, Anura: Due to minute size, overall morphological similarities, scarcity of diagnostic characters after preservation, and usual sympatric or even syntopic occurrence of two or more species of Pseudopaludicola, the taxonomy of the genus is not yet a matter of consensus.
One of these species, Pseudopaludicola ameghini, was subsequently synonymized to P. The influence of climate change on wine production – the case of the Touriga Nacional grape variety Quinta dos Termos, Portugal. The regional and local climate, heavily influenced by global climate change, has strong implications for agriculture. Wine production which has specific characteristics in terms of climate and soil is undoubtedly one of the economic activities strongly influenced by climate change.
Quinta dos Termos located in Beira Interior Belmonte, Portugal is the largest wine producer in the DOC Beira Interior region, producing premium to hiper premium wines of excellence, marketed at both national and international levels, and cultivates the vineyards according to the rules of Integrated Crop Management. Moreover, grapes are free from herbicides, pesticides or any other chemicals that can be harmful to the environment and health. These factors have contributed to the socio-economic development of the region, creating wealth, favoring employment and promoting tourism.
These factors favor unique conditions for the cultivation of Touriga Nacional grape variety, which is recognized by its extremely complex color and aroma, which allows the production of wines with great balance and a good ageing potential. Touriga Nacionala red grape variety of Portuguese origin with high qualitative excellence and reputation and much appreciated worldwide, is versatile to several types of soils and resistant to high thermal amplitudes.
Nevertheless, the climatic changes that has been gradually verified, the type of crop management, and in particular the reputation of Touriga Nacional grape variety, may be compromised in the long term, given that these characteristics are strongly influenced by the climate and soil. Aware of that, Quinta dos Termos has been performing a monitoring of the vineyards in terms of pedological treatment.
Lists the commands to be programed, gives examples, and explains the use of each. A new species of Leptodactylus Fitzinger Anura, Leptodactylidae, Leptodactylinae from montane rock fields of inkitin Chapada Diamantina, northeastern Brazil. In addition, we re-describe the advertisement call ofL.
What are the most important factors determining different vegetation types in the Chapada Diamantina, Brazil? A dendrogram of similarity was generated using the Jaccard Index based on a matrix of the species that occurred in at least two of the vegetation types examined.
The proportions of life forms in each vegetation type were compared using the chi-square test. Composite soil samples were analyzed by simple variance ANOVA to examine relationships between soil parameters of each vegetation type and the transition area.
The monthly precipitation levels in each vegetation type were measured and compared using the chi-square test. A total of species of angiosperms were collected distributed in genera and 54 families. The chi-square test did not demonstrate any significant statistical differences between the monthly values of recorded rainfall.
The organic matter and clay contents of the soilsin the caatinga increased while sand decreased, and the proportions of therophyte, hemicryptophyte, and chamaephyte life forms decreased and phanerophytes increased.
We can therefore conclude that the floristic composition and the spectrum of life forms combined to define the cerrado and caatinga vegetation along the transect examined, with soil being the principal conditioning se determining the different vegetation types, independent of precipitation levels. Mabuyidae from Chapada do Araripe, northeastern Brazil.

Allozyme diversity and morphometrics of Melocactus paucispinus Cactaceae and evidence for hybridization with M. Melocacatus paucispinus Cactaceae is endemic to the state of Bahia, Brazil, and due to its rarity and desirability to collectors it has been considered threatened with extinction.
This species is usually sympatric and inter-fertile with M. Levels of genetic and morphological variation and sub-structuring in completto of these species were assessed and an attempt was made to verify the occurrence of natural hybridization between them.
Genetic variability was surveyed using allozymes 12 loci and morphological variability using multivariate morphometric analyses nikiin vegetative characters in ten populations of M.
Deficit of heterozygotes within the populations was detected in both species, with high values of F IS 0. Evidence of hybridization was detected by the relative allele frequency in the two diaphorase loci.
The evidence indicates the occurrence of introgression in both species at two sites. The high F ST values cannot be explained by geographical substructuring, but are consistent with hybridization. Conversely, morphological differentiation in M. His first astronomer was Francisco Jose de Caldas. By the turn of the century, Julio Garavito worked lubro celestial mechanics—a crater on the niktin side of the Moon bears his name High spatial resolution mapping of the Cerrado’s land cover and land use types in the priority area for conservation Chapada da Contagem, Brazil.
The Brazilian savanna, Cerrado, is the second largest biome over South America and the most floristically diverse savanna in the world. This biome is considered a conservation hotspot in respect to its biodiversity importance and rapid transformation of its landscape. The Cerrado’s natural vegetation has been severely transformed by agriculture and pasture activities. Currently it is the main agricultural frontier in Brazil and one of the most threatened Brazilian biomes.
This scenario results in environmental impacts such as ecosystems fragmentation as well as losses in connectivity, biodiversity and gene flow, changes in the microclimate and energy, carbon and nutrients cycles, among others. The Priority Areas for Conservation is a governmental program from Brazil that identifies areas with high conservation priority.
Economiq of this program’s recommendation is a natural vegetation map including their major ecosystem classes. This study aims to generate more precise information for the Cerrado’s vegetation.

In order to test methods, the priority area for conservation Chapada da Contagem was selected as the study site. This area is ranked as “extremely high priority” by the government and is located in the Federal District and Goias State, Brazil.
Satellites with finer spatial resolution may improve the classification of the Cerrado’s vegetation. Remote sensing methods and two criteria were tested using RapidEye 3A imagery 5m spatial resolution collected in in order to classify the Cerrado’s major land cover types of this area, as well as its land use.
One criterion considers the Cerrado’s major terrestrial ecosystems, which are divided into forest, savanna and grassland. The other involves scaling it down to the major physiognomic groups of each ecosystem. Other sources of environmental dataset such. The high FST values cannot be explained by geographical substructuring, but are consistent with hybridization. Description of a new species of Characidium Reinhardt, Characiformes: Crenuchidae from the Chapada Diamantina, Bahia, and redescription of Characidium bimaculatum Fowler, The coompleto species can be distinguished from its congeners except C.
Among other features, the new species differs from C. Characidium bimaculatum, a poorly known species from Northeastern Brazil, is redescribed. We analysed the trend of the ownership of each IEN variable and evonomia distribution of the households’ scores.

We calculated the correlation coefficients of each variable separately with the IEN score and the household income. We also evaluated how the changes of the score distribution over time affected the validity of the published reference cut-points. We used data from consortium surveys conducted every two years from to in the city of Pelotas, Brazil. An increase in the educational level of household heads and in the ownership of all IEN assets, except radio and telephone, was observed in the study period.
In general, the correlation of the assets with the IEN scores decreased over time. There was an increase in the score, with a consequent increase in the quintiles cut-points, but the distance between these cut-points had no significant variation. Thus, the reference cut-points for Pelotas, quickly became outdated. Some assets showed greatly reduction on its importance for the indicator, and the reference cut-points became obsolete very quickly. It is essential for a standardized wealth or asset index with research purposes to be updated frequently, especially the cut-points of reference distribution.
In Peru, the industry’s development has made economic improvements but at the same time, it has had a major impact on the health of the workers; for that reason, it was necessary to generate control mechanisms.
So, in it was created the Departmento de Higiene Industrial, which in was changed to Instituto de Salud Ocupacional, but it was deactivated in DOS cones along atomic chains. Variations of the local density of states DOS along the chain are investigated.
They are crucial in scanning tunnelling experiments and give important insight into the electron transport mechanism and charge distribution inside chains. It is found that depending on the chain parity the local DOS at the Fermi level can form cone-like structures DOS cones along the chain. The general condition for the local DOS oscillations is obtained and the linear behaviour of the local density function is confirmed analytically.
DOS cones are characterized by a linear decay lbro the chain which is in contrast to the propagation properties of charge density waves, end states and Friedel oscillations in one-dimensional systems.

We find that Lubro cones can appear due to non-resonant electron transport, the spin-orbit scattering or for chains fabricated on a substrate with localized electrons. It is also shown that for imperfect chains e. The evaluation included a quantitative diagnostic CCD photometry on the quality of the local sky. The attributes of the 1-m telescope, the current instrumentation and a well planned upgrading that includes new instrumentation is considered at the basis for a successful transition maintaining the attractiveness of the site for astronomy education.
A 3-year upgrading program actually in progress at UNAM is providing funding for that purpose. Physics and astronomy programs at college and graduated levels at UNAM will benefit from this, yielding clear connections among astronomy researchers and educators and students at various levels.
Although the OAN-Tonantzintla faces the danger of nimitin its sky conditions, we are maintaining awareness of the night sky characteristics in long-term monitoring campaigns and encouraging the local authorities to find alternative solutions to this problem.
