"Joãozinho", hospital de S. João do Porto

The purpose of this research is to recommend a brand identity for Joãozinho brand. This one is linked with the new pediatric hospital of Hospital de São João do Porto and with the fundraising project named “Um Lugar para o Joãozinho”. For this, a 360º market research, with the most important stakeholders, was conducted. The aim was to comprehend how children perceived the brand’s mascot (Joãozinho), what characteristics of a pediatric service parents look for, what makes companies help this project (either through sponsorship agreements or other means of financial aid) and what do brand builders want for the brand.

Genetic differentiation of disjunct populations of the ants Formicaaquilonia and Formica lugubris in Europe.

The species Formica aquilonia and F. lugubris of the mound-building red wood ants have a disjunct boreoalpine distribution in Europe. The populations of F. aquilonia in Finland, Switzerland and the British Isles show little genetic differentiation, whereas the populations of F. lugubris show considerable differentiation. The Central European populations morphologically identified as F. lugubris can be genetically divided into two groups (here called types A and B). Type B is found in the Alps and the Jura mountains, and is genetically inseparable from F. aquilonia. Type A lives sympatrically with type B in the Jura mountains and is also found in the British Isles. Sympatry of the two types in the Jura shows that these are separate species. It remains open whether type B is morphologically atypical F. aquilonia or whether it is a separate species, perhaps with a past history of introgression between F. aquilonia and F. lugubris. The gene frequencies in the Finnish populations of F. lugubris differ from those of both types A and B. Genetic differences within F. lugubris indicate that the populations have evolved separately for a long time. The social structure of F. lugubris colonies also shows geographic variation. The nests in Finland and the British Isles seem to be mainly monogynous and monodomous, whereas the nests in Central Europe are polygynous and form polydomous colonies. F. aquilonia has polygynous and polydomous colonies in all populations studied.

Functional diversity decreases with temperature in high elevation ant fauna

1. Severe environmental conditions filter community species compositions, forming clines of functional diversity along environmental gradients. Here, the changes in functional diversity in ant assemblages with severe environmental conditions in the Swiss Alps were investigated. 2. Eight sites were sampled along an elevation gradient (1800-2550 m). The variation in functional diversity was analysed along an elevation gradient considering four traits: social structure (monogynous vs. polygynous), worker size, pupal development, and nest structure. 3. Ant species richness and functional diversity decreased with decreasing temperature. Species found in colder habitats tended to live in subterranean nests rather than in mounds and exhibit a polymorphism in queen number, either within or across populations. The phylogenetic diversity did not decrease at colder temperature: Formicinae and Myrmicinae occupied the full range of elevations investigated. 4. An insulation experiment indicated that mounds are more thermally insulated against the cold compared with soil. The absence of a mound-building ant from high elevations probably results from a reduction in the amount of vegetal materials provided by coniferous trees. 5. More severe abiotic conditions at higher elevations act as a filter on ant assemblages, directly through physiological tolerances to the abiotic conditions and indirectly as the vegetation necessary for nest building shifts with elevation.</list-item

Current status of the whitefly Aleurodicus dispersus as an invasive pest in the CapeVerte Islands

In the last three decades, the spiralling whitefly (Aleurodicus dispersus) has become an important international pest. The movement of plants and parts of plants (such as fruits) in international trade and tourism, and by natural dispersal, has favoured its introduction to new areas. In common with others whiteflies of economic importance, the immature and adult stages cause direct feeding damage by piercing and sucking of sap from foliage, and indirect damage following the accumulation all over host plants of honeydew and waxy flocculent material produced by the insects. Spiralling whitefly is a pest of tropical and subtropical crops, and highly polyphagous. Up to the 1970s, it had been recorded on 44 genera of plants, belonging to 26 botanical families (Mound & Halsey, 1978). This situation changed with the dispersal of the pest to new areas. Nowadays, the spiralling whitefly is one of the major pest of vegetable, ornamental and fruit crops around the globe (Lambkin, 1999). Important host crops include: banana (Musa sapientum), Citrus spp., coconut (Cocos nocifera), eggplant (Solanum melanogena), guava (Psidium guajava), Hibiscus rosa sinensis, Indian almond (Terminalia catappa), papya (Carica papaya), Rosa sp. and tomato (Lycopersicon esculentum) (Saminathan & Jayaraj, 2001). Spiralling whitefly has its origin in the tropical Americas, including Brazil. Although the pest has been recorded only once in Brasil, in the 1920s in the state of Bahia (Bondar, 1923), it now has official quarantine status because of its economic importance. In the Cape Verte Islands, on the West African coast, the pest was initially introduced in the first half of 2000; it has since become established, reaching urban, natural and agricultural areas of the islands that constitute the archipelago. Since then, the pest has been causing damage to many native plants, ornamentals and cultivated food crops (Anon., 2001; Monteiro, 2004). The present study was done in order to produce an inventory of the most common host plants of spiralling whitefly in this new habitat.

Nestmate recognition and the genetic relatedness of nests in the ant Formica pratensis

Genetic relatedness of the mound-building ant Formica pratensis was determined by means of microsatellite DNA polymorphism, and its impact on nestmate recognition was tested in a population in Southern Sweden (Oeland). Recognition between nests was measured by testing aggression levels between single pairs of workers. The genetic distances of nests (Nei's genetic distance) and the spatial distance of nests were correlated and both showed a strong relation to the aggression behavior. Multiple regression analysis revealed a stronger impact of genetic relatedness rather than spatial distances on aggression behavior. Neighbouring nests were more closely related than distant nests, which may reflect budding as a possible spreading mechanism. The genetic distance data showed that nestmate recognition was strongly genetically influenced in F. pratensis.

A Importância do Ecoturismo no Património Arquitectónico de Cabo Verde das Potencialidades à Prática

Desde a última década do séc. XX, o turismo em Cabo Verde tem sido um dos sectores que mais cresce, atraindo maior investimento directo estrangeiro. Contudo, este crescimento gerou também maior pressão sobre os recursos existentes, com impactes negativos a vários níveis. Tem-se reflectido e discutido a sustentabilidade do turismo em território nacional, com objectivos claros de valorização do destino turístico cabo-verdiano, através da conservação e melhoria do ambiente natural, social e cultural. A aposta das autoridades cabo-verdianas no incremento do turismo para o séc. XXI levou a eleição do ecoturismo como a actividade de futuro, com o objectivo de melhorar a competitividade da oferta turística, ser uma alternativa no sector. Uma actividade que pode ser implementada em qualquer ilha, desde que bem aproveitada a vasta oferta de produtos existentes, envolva e forme a população da importância da conservação da biodiversidade e contribua para a erradicação da pobreza ao gerar recursos económicos para as comunidades locais. Deste modo, se requer pensar que arquitectura para o planeamento e realização de infra- estruturas físicas para o adequado desenvolvimento do ecoturismo em Cabo Verde. Os actores directos como os arquitectos, engenheiros civis e planeadores têm uma enorme responsabilidade ao desenhar e executar obras para o turismo, sobre tudo em ecossistemas de grande fragilidade como os que caracterizam as áreas naturais. Sendo um assunto relativamente recente no país, ainda não se criaram normas, regras, directivas claras para o desenvolvimento deste tipo de infra-estruturas turísticas. Em muitos casos, são os próprios desenhadores e construtores, bem como aos seus clientes, quando demonstram alguma sensibilidade na conservação e preservação de áreas de significação ecológica, estabelecem os seus próprios critérios de desenho e códigos éticos que garantam o mínimo de impacte ambiental e uma interacção harmoniosa e sustentável entre a obra física e os espaços circundantes. O presente trabalho tem como objectivo discutir e analisar qual a importância do ecoturismo no panorama arquitectónico cabo-verdiano e se este turismo sustentável será apenas uma ideia teórica, um modelo ideal de actividade ou passível de ser aplicável, de se observar na prática.

Sex-ratio regulation: the economics of fratricide in ants

In many insect societies, workers can manipulate the reproductive output of their colony by killing kin of lesser value to them. For instance, workers of the mound-building For mica exsecta eliminate male brood in colonies headed by a single-mated queen. By combining an inclusive fitness model and empirical data, we investigated the selective causes underlying these fratricides. Our model examines until which threshold stage in male brood development do the workers benefit from eliminating males to rear extra females instead. We then determined the minimal developmental stage reached by male larvae before elimination in F. exsecta field colonies. Surprisingly, many male larvae were kept until they were close to pupation, and only then eliminated. According to our model, part of the eliminated males were so large that workers would not benefit from replacing them with new females. Moreover, males were eliminated late in the season, so that new females could no longer be initiated, because matings take place synchronously during a short period. Together, these results indicate that workers did not replace male brood with new females, but rather reduced total brood size during late larval development. Male destruction was probably triggered by resource limitation, and the timing of brood elimination suggests that males may have been fed to females when these start to grow exponentially during the final larval stage. Hence, the evolution of fratricides in ants is best explained by a combination of ecological, demographic and genetic parameters.

Building a Social Accounting Matrix within the ESA95 Framework: Obtaining a Dataset for Applied General Equilibrium Modelling

This research provides a description of the process followed in order to assemble a "Social Accounting Matrix" for Spain corresponding to the year 2000 (SAMSP00). As argued in the paper, this process attempts to reconcile ESA95 conventions with requirements of applied general equilibrium modelling. Particularly, problems related to the level of aggregation of net taxation data, and to the valuation system used for expressing the monetary value of input-output transactions have deserved special attention. Since the adoption of ESA95 conventions, input-output transactions have been preferably valued at basic prices, which impose additional difficulties on modellers interested in computing applied general equilibrium models. This paper addresses these difficulties by developing a procedure that allows SAM-builders to change the valuation system of input-output transactions conveniently. In addition, this procedure produces new data related to net taxation information.

Integrative taxonomy of the Formica rufa group (Hymenoptera: Formicidae)

RESUME :Les fourmis du groupe Formica rufa, ou fourmis des bois, ainsi appelées en raison de leur préférence pour les écosystèmes forestiers, sont parmi les fourmis les plus fascinantes et les plus étudiées d'Europe. Ces fourmis jouent un rôle clé dans la plupart des forêts dans lesquelles elles vivent et sont considérées comme étant les meilleurs bioindicateurs de ces milieux. Pour ces raisons, les fourmis des bois sont protégées par la loi dans de nombreux pays européens, y compris en Suisse. Cependant, malgré leur protection, ces fourmis sont inscrites sur la liste rouge des espèces menacées dans plusieurs pays d'Europe et il est donc indispensable de bien les connaître afin de mieux les protéger.À l'heure actuelle, on considère que le groupe Formica rufa est composé de six espèces distinctes : F. rufa, F. polyctena, F. lugubris, F. paralugubris, F. aquilonia et F. pratensis. Toutefois, malgré la grande quantité d'études effectuées sur ces espèces, la systématique et l'identification des fourmis des bois sont toujours sujettes à discussion. Ceci est essentiellement dû au fait que ces espèces sont morphologiquement similaires et qu'elles sont parfois capables de s'hybrider ou de former des colonies mixtes.Une des conditions fondamentales pour toute étude en biologie de la conservation est l'identification correcte des espèces à protéger. Avec cette étude, nous désirons donc dénouer les problèmes liés à la systématique des fourmis des bois et analyser la diversité de ces espèces en adoptant une approche multidisciplinaire.Nous avons d'abord étudié la distribution des espèces jumelles F. lugubris et F. paralugubris dans les Álpes italiennes en re-analysant l'une des plus grandes collections de références sur ces espèces, déposée à l'Université de Pavie, Italie, et en récoltant de nouveaux échantillons sur le terrain. Nos analyses ont montré que F, paralugubris, décrite récemment et souvent «oubliée »par les chercheurs, est bien présente dans les Alpes et vit souvent en sympathie avec F. lugubris. Ensuite nous avons développé un outil moléculaire basé sur l'ADN mitochondrial pour une identification rapide et efficace de ces deux espèces. Au vu des bons résultats, nous avons étendu nos analyses génétiques (microsatellites) à toutes les espèces du groupe F. rufa, ce qui nous a permis de montrer que les outils moléculaires sont très efficaces pour identifier ces fourmis. En outre, nos analyses ont mis en évidence la présence d'une nouvelle espèce cryptique (appelée F. lugubris-X) au sein du Parc National Suisse. L'existence d'une nouvelle espèce peut avoir une grande influence sur les projets de conservation en faveur de ces espèces. Nous avons donc décidé de confirmer ce résultat avec des analyses comportementales et des analyses chimiques basées sur les phéromones sexuelles des différentes espèces, y compris F. lugubris-X. Les deux approches confirment nos données génétiques et indiquent que F. lugubris-X représente bel et bien une nouvelle espèce de fourmis des bois dans les Alpes Suisses.Les résultats de cette étude ont une grande importance du point de vue de la biodiversité. En plus, ils livrent aux futurs chercheurs des outils fiables pour l'identification des fourmis des bois et ouvrent de captivantes perspectives pour une meilleure protection de ces insectes et, par conséquent, de nos écosystèmes forestiers. .Abstract :Mound building red wood ants (species of the Formica rufa group) belong to one of the most studied groups of ants in Europe and have fundamental roles and positive effects in forested habitats of the northern hemisphere. In addition, they are considered among the most promising bioindicators of forest ecosystems. Because of their importance, these ants are protected by law in many European countries, including Switzerland. However, despite this protection, they are included on the red list of threatened species edited by the International Union for Conservation of Nature (IUCN) and on the red list of some particular countries like Switzerland. Because of their similar morphology and a high intraspecific variability, the morphological identification of these species can be quite complicated. In addition, they are sometimes able to hybridize or to form mixed colonies. Consequently, the taxonomy of this group of ants has been much debated during the past decades. Based on a phylogenetic study, today the group is considered to count six species in Europe: F. rufa, F. po/yctena, F. lugubris, F. paralugubris, F. aquilonia and F. pratensis. Nevertheless, the taxonomy of the group is often neglected mainly due to the lack of reliable and easy to use identification methods.Considering the importance of correct species assessment in conservation biology, in this study we want to disentangle the taxonomical difficulties within the Formica rufa group and to clarify the diversity of these protected ants, by using an integrative approach.We first analyzed the distribution of .the sibling species F. lugubris and F. paralugubris in the Italian Alps by collecting new samples on the field and by examining one of the major red wood ant collections, which is deposited at the University of Pavia, Italy. After that, we developed a molecular tool based on mitochondria) DNA, which provides a reliable and easy-to-use technique for the identification of F. lugubris and F. paralugubris. Afterwards, we extended the use of molecular markers for species identification to the whole F. rufa group and made a microsatellite analysis. Results confirm that molecular markers are consistent tools for species identification and that the six known species represent six different genetic pools. In addition, genetic data highlighted the existence of a new cryptic species in the Swiss Alps, called Formica lugubris-X.The presence of a new species can have a great influence on future conservation plans in favour of these protected ants and consequently for forested habitats. We therefore completed molecular data by behavioural (pupae recognition) and chemical analyses based on six pheromones of the entire F. rufa group. Both approaches are in accordance to genetic results and confirm that F. lugubris-X really represents a new cryptic species of red wood ant within the Swiss National Park (Eastern Swiss Alps).Results obtained in this study have a great importance in terms of biodiversity. Moreover, they provide important taxonomical information, reliable tools for species identifications and future perspectives for a consequent conservation of red wood ant species.

Laajakaistayhteyksien vertailua käyttäjän ja rakennuttajan näkökulmasta

Diplomityön tarkoituksena on selvittää eri laajakaistatekniikoiden ominaisuuksia, ja verrata niitä käyttäjien ja rakennuttajien näkökulmaan. Miten käyttäjätsuhtautuvat tekniikan kehittymiseen, ja mitä he ovat valmiita maksamaan siitä. Ovatko näkemykset rakentajien kanssa samansuuntaisia, vai onko tekniikka edellä käyttäjiä? Näihin kysymyksiin pyrittiin saamaan vastaus tässä diplomityössä haastattelemalla molempia osapuolia ja vertailemalla vastauksia. Laajakaistayhteydet ovat lähes kaikkien saatavilla nykypäivänä. Suurin osa yhteyksistä on toteutettu kuparitekniikoilla, joista ADSL on yleisin kaapeli-TV ratkaisun kanssa. Harvemmin asutuilla tai muuten hankalasti tavoitettavilla alueilla laajakaistayhteydet ovat toteutettu langattomin ratkaisuin WiMAX- tai @450-tekniikoilla. Laajakaistayhteyksien kriteerinä on ollut 256 kbit/s nopeus, mutta nykyään käyttäjien keskiarvo on noussut 2 Mbit/s nopeuteen. Nopeudet vaikuttavat sovelluksiin, mitä voidaan käyttää. Nykyään Internetin kautta on saatavilla monipuolisesti erilaisia sovelluksia ja viestintätapoja. Vaatimukset laajakaistayhteyksiltä ovat erilaisia; toiset vaativat reaaliaikaisuutta ja suurta nopeutta ja samalla toiset tyytyvät vähempään. Kaikille yhteyksille on kuitenkin yhteistä se, että niiden käyttövaatimukset ovat kasvaneet jatkuvasti. Tulevaisuutta onpyritty kartoittamaan tekniikoiden mahdollisesta kehitysnäkökulmasta, sekä sillä, miten muualla maailmassa edetään laajakaistatekniikoiden kanssa. Oman vivahteen kehitykseen tuovat kansalliset tarpeet ja resurssit.
