Among insects, which are the most diverse eukaryotic group on earth, Lepidoptera is one of four enormously diverse orders, with approximately 10,000 described species in North America. Within the order, Nearctic “microlepidoptera,” which represent an overwhelmingly large percentage of diversity within the order, remain poorly known despite their ecological importance in many plant communities. In this thesis, I undertook several studies of microlepidoptera diversity in a natural community type (hill prairie) and a managed community type (biofuel feedstock). In two Illinois hill prairies differing in size, latitude, and plant composition, alpha diversity of Pyraloidea and Tortricidae was similar, but the prairies were found to support different sets of species of these moth groups. It is concluded that the similarity in alpha diversity occurs because the larger prairie supports primarily a complement of moth species that feed as larvae on prairie plants (especially species of Asteraceae and Fabaceae), whereas the moths collected in the small prairie represent relatively few prairie-associated species, plus a large component of species that feed as larvae on deciduous trees that surround the prairie. This agrees with the finding of high beta diversity of moths between the sites, which reflects a high level of larval hostplant specificity in most species of Pyraloidea and Tortricidae. Based on published information plus observations made on microlepidoptera collected during the course of this study, 31 families of basal microlepidoptera were reviewed with an aim toward evaluating the likelihood of their including species that are dependent on tallgrass prairie. Of these families, 12 were evaluated as possible, and two as likely or certain, to include prairie-dependent species. In a comparison of moth diversity in light-trap samples from corn, miscanthus, switchgrass, and native prairie, alpha diversity was highest in prairie and was higher in switchgrass than in the other two biofuel crops. Moth species complements generally were similar among the biofuel crops, and prairie shared higher species complementarity with switchgrass than with corn or miscanthus. These findings suggest that large-scale conversion of land to biofuel crops may, to a substantial degree, detrimentally affect arthropod biodiversity, with a resulting loss of valuable arthropod-derived ecosystem services both within the cropping systems and in the surrounding landscape. During the course of this study, rearing efforts yielded two species of moths of the family Gelechiidae, both of which are monophagous leaf feeders on leadplant, Amorpha canescens (Fabaceae). Because these moths are restricted to tallgrass prairie, they are likely to be of interest to conservation biologists. In the interest of naming the moths to facilitate communication regarding them, and to augment our taxonomic knowledge of their respective genera, the moths are described, and diagnoses are provided to differentiate them from similar, related species.

A inclusão da comunidade cigana requer uma postura diferente por parte desta comunidade que passa pela assunção das normas por que todos os cidadãos portugueses se devem reger, em termos de direitos e deveres, exercendo a sua cidadania plena, de forma ativa e participada. Objetivo: Promover a inclusão das crianças ciganas nas escolas do Concelho do Seixal. Metodologia: utilizou-se a metodologia de planeamento em saúde, recorrendo à entrevista e grelha de observação, como instrumentos de recolha de dados. Resultados: Deficit de conhecimentos sobre cuidados de higiene nas crianças ciganas; Deficit de conhecimentos sobre cultura cigana pelos professores; Desvalorização da preservação dos espaços comuns do bairro pelas famílias ciganas. Conclusões: Importância da promoção de hábitos de higiene pessoal junto das crianças ciganas, necessidade de formação para professores sobre multiculturalidade e cultura cigana e de intervenção articulada e em parceria, no bairro, promovendo a mudança de comportamentos para preservação dos espaços comuns; ABSTRACT: The inclusion of the Roma community requires a different attitude on the part of this community that goes by the assumption of standards that all Portuguese citizens should be governed in terms of rights and duties, exercising their full citizenship, active and participatory way. Objective: To promote the inclusion of Roma children in the Municipality of Seixal schools. Methodology used the health planning methodology, using interview and observation grid, such as data collection tools. Results: Deficit of knowledge about hygiene in the Roma children; Deficit of knowledge about Roma culture by teachers; Devaluation of preservation of the common areas of the neighborhood by Roma families. Conclusions: The importance of promoting personal hygiene habits with Roma children, the need for training for teachers on multiculturalism and gypsy culture and coordinated intervention and partnership, in the neighborhood, promoting behavior change to preserving public spaces.

Plodia interpunctella (Indian meal moth) is a cosmopolitan pest that attacks not only a wide range of stored grain as well other food products. Due to its economic importance several researches have focused in a method with ability to control this pest with few or no damage to the environment. The study of digestive enzymes inhibitors, lectins and chitin-binding proteins, has often been proposed as an alternative to reduce insect damage. In this study we report the major classes of digestive enzymes during larval growth in P. Interpunctella, being those proteinases actives at pH 9.5 and optimum temperature of 50 oC to both larvae of the 3rd instar and pre-pupal stage of development. In vitro and zymogram assays presented the effects of several inhibitors, such as SBTI, TLCK and PMSF to intestinal homogenate of 3rd instar larvae of 62%, 92% and 87% of inhibition and In pre-pupal stage of 87%, 62 % and 55% of inhibition, respectively. Zymograms showed inhibition of two low molecular masses protein bands by TLCK and that in presence of SBTI were retarded. These results are indicative of predominance of digestive serine proteinases in gut homogenate from Plodia interpunctella larvae. This serine proteinase was then used as a target to evaluate the effect of SBTI on larvae in in vivo assay. Effect of SBTI on mortality and larval mass was not observed at until 4% of concentration (w/w) in diets. Chitin, another target to insecticidal proteins, was observed by chemical method. Moreover, optic microscopy confirmed the presence of a peritrophic membrane. Established this target, in vivo effect of EvV, a chitin binding vicilin, evaluated during the larval development of P. interpunctella and was obtained a LD50 of 0,23% and WD50 of 0,27% to this protein. Mechanism of action was proposed through of the in vivo digestibility of EvV methodology. During the passage through the larval digestive tract was observed that EvV was susceptible to digestive enzymes and a reactive fragment, visualized by Western blotting, produced by digestion was recovered after dissociation of the peritrophic membrane. The bound of EvV to peritrophic membrane was confirmed by immunohystochemical assays that showed strong immunofluorescent signal of EvV-FITC binding and peritrophic membrane. These results are a indicative that vicilins could be utilized as potential insecticide to Plodia interpunctella and a control methods using EvV as bioinsecticide should be studied to reduce lost caused by storage insect pests

El punto de partida de nuestro estudio se sitúa en el polémico y discutido asunto resuelto por la sentencia del Tribunal Europeo de Derechos Humanos de 8 de diciembre de 2009, Caso Muñoz Díaz c. España, donde se condena al Estado español por denegar la pensión de viudedad a una ciudadana casada exclusivamente por el rito matrimonial gitano. Al hilo de esta resolución analizaremos, entre otras cuestiones, las diversas formas matrimoniales a las que nuestro legislador otorga efectos civiles, la incidencia de dichas disposiciones en el principio de igualdad y no discriminación consagrado en el artículo 14 de la Constitución y en el artículo 14 del Convenio Europeo de Derechos Humanos, y la posible vulneración de dicho principio en el marco de las prestaciones sociales reguladas en la Ley General de la Seguridad Social, recientemente reformada.

The honeydew moth Cryptoblabes gnidiella is the main problem for the wineries in the Northeast of the Brazil, because it attacks the bunch and reduces the quality of the grapes and the wines. In order to stretch out the bunch to facilitate the penetration of the insecticides, it was used gibberellic acid. Six treatments with different concentrations and different dates of application, and the control were compared. The bunches are compact, characteristic of the "Syrah" grapes in the region. The grape berries were analysed at harvest and wines were made by microvinifications. The grape berries showed different qualitative characteristics, as berry weight, number of berries. °Brix, total acidity and heterogeneity of the maturation. The microvinifications were carried out with 50 kg of grapeberries into glass bottles of 20 L at 22°C, for the alcoholic and malolactic fermentations, then stabilized and bottled. The wines were tasted by a panel of ten people and compared on smell and taste plans. The tasting results showed that the control treatment was the best graded wine. The application of gibberellic acid allowed to control the honeydew moth attack, but it caused a heterogeneity on grape maturation, with a lower quality of the grapes and wines compared to the control.

This paper aims at analysing the presence of gypsy characters in two neo-Victorian popular films, namely Joe Johnston’s The Wolfman (2010) and Guy Ritchie’s Sherlock Holmes: Game of Shadows (2011). The cultural construction of nineteenth-century gypsies, those “Others within Europe” (Boyarin 433) whose presence in Victorian fiction was peripheral, spectral and at times invisible (Nord 3-4), is simultaneously exploited and contested by these two neo-Victorian screen narratives to raise issues of otherness and invisibility on the screen. Setting off from the premise that screen texts, just like print texts, can also be participant in the neo-Victorian project of reimagining the underside of Victorian culture for contemporary audiences (Whelehan 273), this paper traces how the adaptation of Victorian gypsies for the screen, true to the palimpsestuous potential inherent to the process of adaptation (Hutcheon 6) and sharing the double drive between past and present which characterises the neo-Victorian genre (Arias and Pulham xiii; Shiller 539), hybridises our cultural memory of the Victorian Age on the screen while concurrently raises concerns over the persistent liminal status of gypsies in contemporary European culture. In particular, this paper illustrates how the tropes prototypically associated to gypsies (namely their nomadic lifestyle, mysticism, alienated existence or their perceived association to criminality) which can be traced back to Victorian culture are deployed on the neo-Victorian popular screen (with varyingly succesful outcomes) to comment on their (in)visibility in the European popular imagination.

Angadenia berteroi is a tropical perennial subshrub of the pine rocklands with large yellow flowers that set very few fruits. My dissertation seeks to elucidate the factors that affect the reproductive fitness of Angadenia berteroi a native species of the south Florida pine rocklands. I provide novel information on the pollination biology of this native species. I also assess the effects of herbivory on growth and the reproductive success of A. berteroi. Finally, I elucidate how habitat fragmentation and quality are correlated with reproductive fitness of this native perennial plant.^ Using a novel experimental approach, I determined the most effective pollinator group. I used nylon fishing line of widths corresponding to proboscis diameter of the major groups of visitors to examine pollen removal and deposition. In the field, I estimated visitation frequency and efficacy of each pollinator type. Using potted plants, I exposed flowers to single visit from different types of pollinators to measure fruit set. I performed artificial defoliation with scissors on plants growing in the greenhouse to assess the effects of defoliation before flowering as well as during flowering. Additionally, I used structural equation modelling (SEM) to elucidate how A. berteroi reproductive fitness was affected by habitat fragmentation and quality. ^ My experiments provide evidence that Angadenia berteroi is specialized for bee pollination; though butterflies, skippers and others also visit its flowers, A. berteroi is exclusively pollinated by two native bees of the South Florida pine rocklands . This research also demonstrated that herbivory by the oleander moth may have direct and indirect effects on Angadenia berteroi growth and reproductive success. The SEM results suggested that habitat quality (litter depth and subcanopy cover) may favor reproduction in native species of the South Florida pine rocklands that are properly maintained by periodic fires and exotic control. Insights from this threatened and charismatic species may provide impetus to properly manage remaining pine rocklands in South Florida for this and other endemic understory species.^

We review the Psychodinae of Mallorca, recognising fifteen species based on recent collections and available literature. Previously unpublished data is presented for eleven species, of which Neoarisemus ibericus Wagner, 1978, Mormia tenebricosa (Vaillant, 1954), Clogmia albipunctata (Williston, 1893), Lepiseodina rothschildi (Eaton, 1913), Paramormia ustulata (Walker, 1856), Philosepedon pyrenaicus Vaillant, 1974 and Psychoda (Psycha) grisescens Tonnoir, 1922 are first records for Mallorca. An old record of Pericoma trifasciata (Meigen, 1804) is considered doubtful. Pericoma unipennata sp. n is described and illustrated based on a male collected at Deía. Distributional data are reviewed for all newly recorded species. Based on the Psychodinae fauna, the zoogeographical affinities of Mallorca are briefly discussed.

A investigação desenvolvida é sobre a empregabilidade e inserção no mercado de trabalho da comunidade cigana portuguesa. Deste ponto de vista, a investigação recai sobre o processo desenvolvido de integração social nas últimas décadas onde se questiona, os Planos de Ação para a Inclusão das Comunidades Ciganas e o seu impacto na vida socioprofissional das mesmas. Para o efeito, será realizado um estudo comparado entre Portugal e Espanha no que concerne ao processo de integração social das comunidades ciganas. Estudos recentes do Instituto Português de Administração e Marketing (IPAM) referem que o emprego é mais difícil de conseguir para pessoas deficientes e pessoas ciganas (os cegos lideram a tabela com 71,6 por cento, seguindo-se a etnia cigana com 47,3).1 Um dos principais obstáculos que se tem verificado em relação à inserção no mercado de trabalho é consequência do problema da discriminação institucional (direta ou indireta)2, relutância por parte das próprias entidades responsáveis pela implementação do desenvolvimento dos programas de emprego. Devido à importância do exercício da cidadania no processo de integração social, realizar-se à uma parte empírica dedicada ao movimento associativo em Portugal e Espanha, de modo a perceber qual o seu envolvimento na definição da política social e respetivas prioridades em relação ao emprego e defesa dos direitos humanos. No quadro da compreensão, será desenvolvido uma investigação qualitativa e quantitativa, com recurso à aplicação de inquérito junto de dirigentes/representantes de ONG´S Ciganas nos dois países, no que concerne à participação/representação das mesmas, na definição de estratégias de intervenção social tendo em conta a politica social nacional e as orientações da União Europeia como é exemplo, a Estratégia Nacional Para a Integração da Comunidade Cigana; EMPLOYABILITY AND INTEGRATION IN THE LABOUR MARKET OF THE GYPSY IN PORTUGAL AND SPAIN Abstract: The research carried out is on employability and inclusion in the Community Portuguese Gypsy labor market. From this point of view, the investigation lies with the developed process of social integration in recent decades where it questions the Action Plans for Inclusion of Roma communities and their impact on the socio-professional life of the community Gypsy. For this purpose, a comparative study between Portugal and Spain regarding the process of social integration of Roma will be held. Recent studies of the Portuguese Institute of Administration and Marketing (IPAM), indicate that employment is more difficult to achieve for disable people and Roma people (the blind lead the table with 71.6 percent, followed by 47%). One of the main obstacles that has been seen in relation to the insertion in the labor market is a result of the problem of institutional discrimination (direct or indirect), reluctance by the very entities responsible for implementing the development of employment programs. Because of the importance of citizenship in the social integration process, carried out the empirical part dedicated to the associative movement in Portugal and Spain, in order to understand what their involvement in the definition of social policy and respective priorities in relation to employment and defense of human rights. In the context of understanding, a qualitative research will be developed, using the application survey of leaders / representatives of NGOs Roma in both countries, with respect to participation / representation of the same in the definition of social intervention strategies taking into account national social policy and the guidelines of the European Union as example, the national Strategy for the Integration of Roma Community.
