Ecofisiologia, fenologia e adaptação de espécies florestais arbóreas nas condições edafoclimáticas de Viana-ES

A intensa atividade humana devasta grandes extensões de florestas nativas, seja para expansão da agricultura seja para suprir a crescente demanda do mercado por madeira, de uma forma ou de outra os pequenos fragmentos florestais remanescentes sofrem constantes pressões antrópicas, contudo, o uso de espécies arbóreas adaptadas pode contribuir para a proteção desses recursos naturais. Buscou-se neste estudo avaliar os padrões fenológicos de 109 espécies florestais arbóreas pertencentes a 37 famílias e 82 gêneros, dentre nativas e exóticas, com nove anos de idade, para diferenciar as mais adaptadas e com potencial de serem utilizadas em programas de reflorestamento. O estudo foi realizado na Fazenda Experimental do Incaper, em Jucuruaba, município de Viana-ES, (UTM E-345524, N- 7741039). Foram realizadas análises químicas do solo na área plantada e os dados climatológicos obtidos na estação meteorológica de Viana. O estudo baseou-se na observação do número de plantas sobreviventes de cada espécie e da avaliação do seu crescimento. Foram realizadas observações das fenofases de brotação, senescência de folhas, floração e frutificação. As avaliações fenológicas foram realizadas em intervalos mensais, no período de novembro de 2012 a outubro de 2013. Realizou-se a medição da altura das árvores, diâmetro à altura do peito (DAP), índice de enfolhamento, taxa de sobrevivência e cálculo do ICC (Índice Combinado de Crescimento), bem como a determinação das espécies mais adaptadas. Das 109 espécies estudadas, 64,22% apresentaram adaptação funcional e estrutural às condições de solo e clima da região experimental, 42,22 % floresceram e frutificaram e 90% apresentaram senescência e brotação acompanhando a sazonalidade climática. Vinte e nove espécies apresentaram ICC maior do que o ICC médio. A maioria das espécies destacou-se como alternativa para recuperação da cobertura vegetal local, com destaque para Inga uruguensis e Schizolobium amazonicum. As análises de fluorescência da clorofila revelaram que o aparato fotossintético da Schizolobium amazonicum foi capaz de protegê-la da fotoinibição e promover boa conversão da energia luminosa em fotoquímica.

Transfering data from a server to an Android Mobile application: a case study

Nowadays, due to the incredible grow of the mobile devices market, when we want to implement a client-server applications we must consider mobile devices limitations. In this paper we discuss which can be the more reliable and fast way to exchange information between a server and an Android mobile application. This is an important issue because with a responsive application the user experience is more enjoyable. In this paper we present a study that test and evaluate two data transfer protocols, socket and HTTP, and three data serialization formats (XML, JSON and Protocol Buffers) using different environments and mobile devices to realize which is the most practical and fast to use.

Distribució actual de la tortuga Mediterrànea a Menorca

A Menorca la tortuga mediterrànea Testudo hermanni és una espècie comuna que es distribueix per quasi tota l'illa. Els estudis anteriors sobre la seva distribució van ser realitzats entre els anys 1970 i 1994. Entre 2003 i 2006 es va prospectar la major part de Menorca amb la finalitat de determinar-ne la distribució actual. A partir de 3647 observacions d'exemplars, se'n va seleccionar aleatòriament una per quadrícula UTM de 0,5 x 0,5 km prospectada. Mitjançant una anàlisi kernel es va calcular que la seva distribució ocupava una superfície de 469 km2 (incloent-hi hàbitats no emprats per les tortugues, com ara zones urbanes o algunes zones boscoses). Aquesta distribució no és continua al llarg de l'illa, sinó que es formada per una sèrie de poblacions més o menys fragmentades i aïllades. D'altra banda, la distribució obtinguda coincideix amb la senyalada en treballs anteriors, la qual cosa s'interpreta com que no hi ha hagut canvis importants en la seva ocupació en els últims deu anys.

Mapping, organic matter mass and water volume of a peatland in Serra do Espinhaço Meridional

Peatlands form in areas where net primary of organic matter production exceeds losses due to the decomposition, leaching or disturbance. Due to their chemical and physical characteristics, bogs can influence water dynamics because they can store large volumes of water in the rainy season and gradually release this water during the other months of the year. In Diamantina, Minas Gerais, Brazil, a peatland in the environmental protection area of Pau-de-Fruta ensures the water supply of 40,000 inhabitants. The hypothesis of this study is that the peat bogs in Pau-de-Fruta act as an environment for carbon storage and a regulator of water flow in the Córrego das Pedras basin. The objective of this study was to estimate the water volume and organic matter mass in this peatland and to study the influence of this environment on the water flow in the Córrego das Pedras basin. The peatland was mapped using 57 transects, at intervals of 100 m. Along all transects, the depth of the peat bog, the Universal Transverse Mercator (UTM) coordinates and altitude were recorded every 20 m and used to calculate the area and volume of the peatland. The water volume was estimated, using a method developed in this study, and the mass of organic matter based on samples from 106 profiles. The peatland covered 81.7 hectares (ha), and stored 497,767 m³ of water, representing 83.7 % of the total volume of the peat bog. The total amount of organic matter (OM) was 45,148 t, corresponding to 552 t ha-1 of OM. The peat bog occupies 11.9 % of the area covered by the Córrego das Pedras basin and stores 77.6 % of the annual water surplus, thus controlling the water flow in the basin and consequently regulating the water course.

Surface mapping, organic matter and water stocks in peatlands of the Serra do Espinhaço meridional - Brazil

Peatlands are soil environments that store carbon and large amounts of water, due to their composition (90 % water), low hydraulic conductivity and a sponge-like behavior. It is estimated that peat bogs cover approximately 4.2 % of the Earth's surface and stock 28.4 % of the soil carbon of the planet. Approximately 612 000 ha of peatlands have been mapped in Brazil, but the peat bogs in the Serra do Espinhaço Meridional (SdEM) were not included. The objective of this study was to map the peat bogs of the northern part of the SdEM and estimate the organic matter pools and water volume they stock. The peat bogs were pre-identified and mapped by GIS and remote sensing techniques, using ArcGIS 9.3, ENVI 4.5 and GPS Track Maker Pro software and the maps validated in the field. Six peat bogs were mapped in detail (1:20,000 and 1:5,000) by transects spaced 100 m and each transect were determined every 20 m, the UTM (Universal Transverse Mercator) coordinates, depth and samples collected for characterization and determination of organic matter, according to the Brazilian System of Soil Classification. In the northern part of SdEM, 14,287.55 ha of peatlands were mapped, distributed over 1,180,109 ha, representing 1.2 % of the total area. These peatlands have an average volume of 170,021,845.00 m³ and stock 6,120,167 t (428.36 t ha-1) of organic matter and 142,138,262 m³ (9,948 m³ ha-1) of water. In the peat bogs of the Serra do Espinhaço Meridional, advanced stages of decomposing (sapric) organic matter predominate, followed by the intermediate stage (hemic). The vertical growth rate of the peatlands ranged between 0.04 and 0.43 mm year-1, while the carbon accumulation rate varied between 6.59 and 37.66 g m-2 year-1. The peat bogs of the SdEM contain the headwaters of important water bodies in the basins of the Jequitinhonha and San Francisco Rivers and store large amounts of organic carbon and water, which is the reason why the protection and preservation of these soil environments is such an urgent and increasing need.

irregular. With reference to the 10 km UTM network, the number of relevés per cell ranges between 0 and 527, with a mean of 36, the most exhaustively prospected areas lying in the Pyrenean range. On the other hand, 44 cells spread ± regularly over the Catalan territory have not available relevés yet, the larger spot lying in the Lluçanés area (C Catalonia). As a general rule. communities seem to be rather adequately prospected and no great discordances between syntaxa have been observed. However. further studies may be required for several alliances such as Berberidion, Pruno-Rubion ulmifolii, Taeniathero-Aegilopion, Alkanno-Malcolmion, Thero-Suaedion, Posidonion or Rupion maritimae.
