Os sistemas de informação geográfica na promoção de um território vinhateiro: aplicação na Região Demarcada do Alentejo

Este trabalho de projeto consistiu na criação de apps de rotas de vinho, particularmente da Rota dos Vinhos do Alentejo e da sub-região da Vidigueira. Foram usadas várias apps story maps para perceber o potencial destas aplicações na representação de rotas enoturísticas e na promoção de territórios vinhateiros. Todas as apps foram criadas num PC e o layout é responsivo, adaptando-se a tablets e smartphones. Com base na revisão bibliográfica e na recolha de dados (entrevista e inquéritos) a stakeholders do mundo do vinho, foram definidos os elementos e as potenciais marcas identitárias que devem constar na Rota dos Vinhos do Alentejo e, em especial, na sub-região da Vidigueira. Os dados recolhidos foram sujeitos a tratamento estatístico, do qual resultou um conjunto de informações organizadas em tabelas, gráficos e quadros-síntese. Esta informação permitiu construir apps para georreferenciação de rotas enoturísticas e promoção de territórios vinhateiros.This project consisted in the creation of wine route apps, particularly of The Alentejo Wine Route and Vidigueira sub-region. Several apps story maps were used to understand the potential of these applications in representing wine routes and promoting wine regions. All apps were created on PC and have responsive layouts that adjust when displayed on tablets and smartphones. Based on literature review and data collection (interview and survey) from wine world´s stakeholders, elements and potential identity marks that should be included on The Alentejo Wine Route and, in particular, in Vidigueira sub-region were defined. The collected data was statistically analyzed, resulting in a set of information organized in tables and summary tables. This information allowed to create apps to georeferencing wine routes and to promote wine territories

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

The complete genome sequence of Chromobacterium violaceum reveals remarkable and exploitable bacterial adaptability

Chromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spread utilization of quorum sensing for control of inducible systems, all of which underpin the versatility and adaptability of the organism. The genome also contains extensive but incomplete arrays of ORFs coding for proteins associated with mammalian pathogenicity, possibly involved in the occasional but often fatal cases of human C. violaceum infection. There is, in addition, a series of previously unknown but important enzymes and secondary metabolites including paraquat-inducible proteins, drug and heavy-metal-resistance proteins, multiple chitinases, and proteins for the detoxification of xenobiotics that may have biotechnological applications

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Aqueous-based nanoemulsion containing (-)-α-bisabolol for topical treatment of skin burns

Background: α-Bisabolol (BIS) is a sesquiterpene extracted from the chamomile flowers, whose use to topically treat burn skin has been reported. High lipophilicity of BIS, however, is a problem for both skin application and washing. Objective: The present study aimed to prepare and characterize a stable and safe aqueous-based nanoemulsion to incorporate BIS and favor skin penetration focusing on skin burns' topical treatment. Methods: Oil-in-water nanoemulsions were obtained from a pseudo-ternary phase diagram. The selected nanoemulsion was characterized (droplet size, PDI, and zeta potential), and the stability was assessed for 60 days at 6ºC and room temperature. The irritability of the formulation was determined by HET-CAM. Skin permeation studies were carried out in vitro intact skin, hot water burn skin, and hot plate burn skin. Results: The nanoemulsion incorporated 1% (w/w) BIS, presented droplets' size of 14.0±0.8 nm (PDI= 0.13±0.02), the zeta potential of +7.5±1.9 mV, and was physically stable over 60 days. The HET-CAM did not show any irritability process provided by the nanoformulation. In the skin permeation experiments, when compared to an oily control solution of BIS, nanoemulsion increased 3.7-fold penetration of the drug in intact skin, likely because the nanoformulation acted as an absorption drug enhancer. On a hot water burn skin model, the increase in drug penetration was 1.7-fold, and in the hot plate burn skin, it was 2.3-fold. Conclusion: The nanoemulsion seems to be a promising alternative for skin burns' topical treatment using this natural active.Faculdade de Ciências da Saúde (FS)Departamento de Enfermagem (FS ENF)Departamento de Farmácia (FS FAR
