Salvador e os sentidos: estratégias de comunicação na web para a construção da marca-cidade

En este artículo analizamos el fenómeno de la marca-lugar en la web. Para ello, examinamos dos videos de propaganda elaborados por el Ayuntamiento de la ciudad de Salvador de Bahía, como una estrategia para atraer a los turistas. En este estudio, buscamos identificar los atributos y valores de la “marca-lugar” de la ciudad de Salvador por intermedio de sus estrategias de comunicación y marketing elaboradas por el órgano de turismo municipal llamado Saltur, en el ambiente propuesto por las redes sociales online, en particular su canal de YouTube.In this article we analyze the phenomenon of place brand in the web environment. Therefore, we present the analysis of two promotional videos developed by Salvador’s town hall, as a strategy to attract tourists. In this study, we identify the attributes and values of Salvador’s place brand through its communication and marketing strategies elaborated by the municipal tourism organ, entitled Saltur, in the environment proposed by online social networks, in particular its Youtube channel.Neste artigo analisamos o fenômeno da marca-lugar no ambiente da web.

Latitude dictates plant diversity effects on instream decomposition

Running waters contribute substantially to global carbon fluxes through decomposition of terrestrial plant litter by aquatic microorganisms and detritivores. Diversity of this litter may influence instream decomposition globally in ways that are not yet understood. We investigated latitudinal differences in decomposition of litter mixtures of low and high functional diversity in 40 streams on 6 continents and spanning 113 degrees of latitude. Despite important variability in our dataset, we found latitudinal differences in the effect of litter functional diversity on decomposition, which we explained as evolutionary adaptations of litter-consuming detritivores to resource availability. Specifically, a balanced diet effect appears to operate at lower latitudes versus a resource concentration effect at higher latitudes. The latitudinal pattern indicates that loss of plant functional diversity will have different consequences on carbon fluxes across the globe, with greater repercussions likely at low latitudes

Avaliação do Padrão de Exatidão Cartográfica em imagens HRC/CBERS-2B após correção geométrica baseada no mosaico Geocover

There are several remote sensing satellites acquiring Earth surface images. Indeed, these satellites generated a large amount of data that have been used in scientific studies as land cover change, disaster monitoring and also cartography. Therefore, it is important to evaluate remote sensing products in terms of positional accuracy. This work aims to assessing positional accuracy of HRC/CBERS-2B (2.7m spatial resolution) prior and after geometric correction based on Geocover data. The accuracy assessment was performed according to the Cartographic Accuracy Standard, as defined by the National Cartography Technical Reference, Brazil. The results showed that before geometric correction HRC image has poor positional accuracy. After geometric correction, based on Geocover data, HRC image substantially increased its positional accuracy. However, despite of high spatial resolution the HRC image geometric corrected by Geocover was classified as class B category at the 1:50,000 scale and does not presented positional accuracy better than Geocover image, which presented class A category at the same scale.Pages: 2375-238

Mean trait values and the CSR ecological strategies

This file contains the mean trait values for leaf morphology, litterfall productivity, stem morphology, stem anatomy and the CSR ecological strategies of 33 Restinga species at Parnamirim, Northeastern Brazil. Leaf and stem samplings were collected from 80 25-m² plots distributed along 16 transects of 100 m-long (five plots per transect). Whenever possible, we collected the organs from the same individuals. Traits and abbreviations: Leaf dry mass (Ldmass), leaf area (Larea), specific leaf area (SLA), leaf moisture (Lmois), stem moisture (Smois), bark (Bark), stem density (Sdens), vessel diameter (Vdiam), vessel density (Vdens), vulnerability index (Vindex), stem length (Slength), stem diameter (Sdiam), litter production (Litter), variability in litter production (Vlitter), leaf-shedding behavior (Lshed) [E=evergreen, SD= semi-deciduous, D=deciduous], and the CSR plant strategy

Mean trait values of leaf anatomy and biochemistry

This file contains the mean trait values of leaf anatomy and biochemistry from 21 Restinga species. Five fully expanded sun leaves with little to no damage were collected from 5 mature individuals per species. Leaves were collected from individuals occurring across 80 25-m² plots distributed along 16 transects of 100 m-long (five plots per transect) in Northeastern Brazil. Leaves were collected within a two-month interval to reduce temporal variation in leaf biochemistry. Traits and abbreviations: Mesophyll thickness (Meso), cuticle thickness (Cuticle), palisade layer per spongy parenchyma layer (P/S), mesophyll layer per total leaf thickness (M/T), starch content (Starch), sucrose content (Sucrose), and total soluble protein (TSP)

Data from: Weak whole-plant trait coordination in a seasonally dry South American stressful environment

A core question involving both plant physiology and community ecology is whether traits from different organs are coordinated across species, beyond pairwise trait correlations. The strength of within-community trait coordination has been hypothesized to increase along gradients of environmental harshness, due to the cost of adopting ecological strategies out of the viable niche space supported by the abiotic conditions. We evaluated the strength of trait relationship and coordination in a stressful environment using 21 leaf and stem traits of 21 deciduous and evergreen woody species from a heath vegetation growing on coastal sandy plain in northeastern South America. The study region faces marked dry season, high soil salinity and acidity, and poor nutritional conditions. Results from multiple factor analyses supported two weak and independent axes of trait coordination, which accounted for 25%–29% of the trait variance using phylogenetically independent contrasts. Trait correlations on the multiple factor analyses main axis fit well with the global plant economic spectrum, with species investing in small leaves and dense stems as opposed to species with softer stems and large leaves. The species’ positions on the main functional axis corresponded to the competitor-stress-tolerant side of Grime's CSR triangle of plant strategies. The weak degree of trait coordination displayed by the heath vegetation species contradicted our expectation of high trait coordination in stressful environmental habitats. The distinct biogeographic origins of the species occurring in the study region and the prevalence of a regional environmental filter coupled with local homogeneous conditions could account for prevalence of trait independence we observed
