Revisão taxonômica e filogenia do gênero Megalobrachium Stimpson, 1858 (Crustacea: Decapoda: Anomura: Porcellanidae)

O presente trabalho trata do gênero de porcelanídeos Megalolobrachium Stimpson, 1858 e está organizado em três partes: (1) uma revisão taxonômica das espécies atualmente atribuídas a Megalobrachium Stimpson, 1858; (2) uma revisão da diversidade morfológica do gênero em um contexto maior dentro de Porcellanidae; e (3) uma análise cladística a partir de dados morfológicos com o intuito de testar o monofiletismo de Megalobrachium e propor a primeira hipótese filogenética para o gênero. A revisão taxonômica se baseou no estudo de material abundante de diferentes localidades do Pacífico oriental e Atlântico ocidental. Uma nova espécie de Megalobrachium é descrita com base no material das costas pacíficas do Panamá e Colômbia, totalizando 13 espécies em Megalobrachium. Para a análise filogenética, foram obtidos 151 caracteres; o grupo-externo foi composto por quatro espécies de três gêneros: Pachycheles Stimpson, 1858, Pisidia Leach, 1820, e Porcellana Lamarck, 1801. Uma única árvore (314 passos; IC: 64; IR: 80) foi obtida, com dois clados. O primeiro clado inclui espécies com lobos da fronte marcadamente flexionados, flagelo da antena curto, com artículos longos, patas ambulatórias curtas e robustas, abdome subtriangular em machos, pleópodo feminino iv com três segmentos, e urópodos curtos. O segundo clado contém espécies com lobos da fronte não flexionados, flagelo da antena longo, com artículos curtos, patas ambulatórias longas e delgadas, abdome sub-retangular, pleópodo feminino iv com dois segmentos, urópodos longos. O primeiro clado corresponde a Porcellanopsis Rathbun, 1910 (espécie-tipo P. festae (Nobili, 1901)), previamente tratado como sinônimo de Megalobrachium. Contudo, a combinação de diferenças morfológicas entre Megalobrachium e Porcellanopsis justifica a revalidação de Porcellanopsis. Três espécies foram erroneamente registradas no Pacífico oriental (M. mortenseni Haig, 1962, P. rosea (Rathbun, 1900) e P. soriata (Say, 1818)); essas espécies são exclusivamente distribuídas no Atlântico ocidental.

Desenvolvimento de sistema automatizado de monitoramento de ambientes de produção animal, utilizando uma rede de sensores sem fio

As redes de sensores sem fio, aplicadas à automação do controle de ambientes representam um paradigma emergente da computação, onde múltiplos nós providos de sensores, sistemas computacionais autônomos e capacidade de comunicação sem fio, conformam uma rede cuja topologia altamente dinâmica permite adquirir informações sobre sistemas complexos sendo monitorados. Um dos fatores essenciais para obter um ganho na produtividade avícola é o controle da ambiência animal. Atualmente os métodos utilizados para o monitoramento e controle ambiental não podem considerar a grande quantidade de microambientes internos nos ambientes de produção animal e também requerem infraestruturas cabeadas complexas. Dentro desse contexto o objetivo deste trabalho foi desenvolver e testar um sistema automatizado de controle ambiental, através da utilização de sensores sem fio, que auxilie e proporcione maior segurança no controle de ambientes automatizados. O sistema monitora variáveis que influenciam na produtividade de aves, tais como temperatura e umidade e outras variáveis físico-químicas do aviário. A infraestrutura desenvolvida foi testada em um aviário experimental e resultou em um sistema seguro e com grande escalabilidade, que é capaz de controlar e monitorar o ambiente e ainda coletar e gravar dados. Foi utilizado o protocolo ZigBee® para gerenciar o fluxo de dados do sistema. Foram feitas análises da eficiência de comunicação do sistema no aviário, monitorando os pacotes de dados perdidos. Os testes demonstraram uma perda de dados de aproximadamente 2% dos pacotes enviados, demonstrando a eficiência das redes ZigBee® para gerenciar o fluxo de dados no interior do aviário. Desta forma, pode-se concluir que é possível e viável a implantação de uma rede ZigBee®, para automatizar ambientes de produção animal com coleta de dados em tempo real, utilizando um sistema integrado via internet, que compreende: instrumentação eletrônica, comunicação sem fio e engenharia de software\".

Morfologia, taxonomia e análise cladística da tribo Kingsleyini (Crustacea: Decapoda: Pseudothelphusidae)

Kingsleyini corresponde a uma das cinco tribos de Pseudothelphusidae, grupo exclusivamente americano de caranguejos de água doce. Atualmente a tribo inclui 59 espécies agrupadas em 13 gêneros, com distribuição associada aos rios, riachos e igarapés das bacias do Amazonas e do Orinoco. Desde a criação de Kingsleyini o aumento de novos táxons atribuídos a esta tribo não tem sido acompanhado por estudos cladísticos. No presente trabalho é realizada a análise cladística de Kingsleyini, acompanhada de uma revisão morfológica e taxonômica do grupo. Com este propósito, foram estudados espécimes de 60 espécies representantes das cinco tribos e duas subfamílias inclusas em Pseudothelphusidae. O material estudado se encontra depositado nas coleções carcinológicas de seis instituições e inclui os tipos nominais de 29 espécies. Na revisão morfológica foram descritas e ilustradas estruturas somáticas e sexuais da morfologia externa do grupo de estudo. Os estudos morfológicos foram auxiliados por técnicas de Microscopia Electrônica de Varredura (MEV) e cortes histológicos. A partir destas observações foram propostas modificações na terminologia utilizada para denominar as estruturas do primeiro apêndice sexual masculino (primeiro gonópodo) em Kingsleyini. A parte taxonômica deste trabalho inclui chaves de identificação, mapas de distribuição, listas sinonímicas e a descrição e ilustração do primeiro apêndice sexual masculino para a grande maioria das espécies examinadas, assim como a diagnose dos gêneros considerados monofiléticos. A análise filogenética foi realizada a partir de 92 caracteres obtidos de 57 táxons terminais: 49 terminais do grupo interno (Kingsleyini) e oito do grupo-externo (representantes dos demais Pseudothelphusidae). Como resultado da análise cladística foram obtidas seis hipóteses filogenéticas igualmente parcimoniosas: todas elas apoiam o monofiletismo de Kingsleyini e a exclusão do gênero Spirocarcinus da tribo. O monofiletismo dos gêneros Fredius, Kingsleya, Eudaniela e Rodriguezus também encontra-se sustentado em todas as hipóteses filogenéticas obtidas, enquanto que os gêneros Microthelphusa, Neopseudothelphusa, Orthothelphusa e Brasiliothelphusa revelaram-se parafiléticos.

Evaluation of an integrated system for classification, assessment and comparison of services for long-term care in Europe: the eDESDE-LTC study

Background: The harmonization of European health systems brings with it a need for tools to allow the standardized collection of information about medical care. A common coding system and standards for the description of services are needed to allow local data to be incorporated into evidence-informed policy, and to permit equity and mobility to be assessed. The aim of this project has been to design such a classification and a related tool for the coding of services for Long Term Care (DESDE-LTC), based on the European Service Mapping Schedule (ESMS). Methods: The development of DESDE-LTC followed an iterative process using nominal groups in 6 European countries. 54 researchers and stakeholders in health and social services contributed to this process. In order to classify services, we use the minimal organization unit or “Basic Stable Input of Care” (BSIC), coded by its principal function or “Main Type of Care” (MTC). The evaluation of the tool included an analysis of feasibility, consistency, ontology, inter-rater reliability, Boolean Factor Analysis, and a preliminary impact analysis (screening, scoping and appraisal). Results: DESDE-LTC includes an alpha-numerical coding system, a glossary and an assessment instrument for mapping and counting LTC. It shows high feasibility, consistency, inter-rater reliability and face, content and construct validity. DESDE-LTC is ontologically consistent. It is regarded by experts as useful and relevant for evidence-informed decision making. Conclusion: DESDE-LTC contributes to establishing a common terminology, taxonomy and coding of LTC services in a European context, and a standard procedure for data collection and international comparison.

Scenarios for the Agricultural Sector in the Southern and Eastern Mediterranean. MEDPRO Report No. 4, March 2013

The paper builds predictive scenarios for the agricultural sector of eleven southern and eastern Mediterranean countries (SEMCs), namely Algeria, Egypt, Israel, Jordan, Lebanon, Libya, Morocco, Palestine, Syria, Tunisia and Turkey. First, it assesses the performance trends of the SEMCs’ agricultural sector, with a focus on production, consumption and trade patterns, incentives, trade protection policies and trade relations with the EU, productivity dynamics and their determinants. Second, it presents four scenarios based on the main value chains of the SEMCs’ agriculture sector: animal products, fruit and vegetables, sugar and edible oils, cereals, fish and other sea products. The four scenarios are: business as usual, Mediterranean – one global player, the EU-Mediterranean area under threat and the EU and SEMCs as regional players on the global stage.

Biosystematics of the Genus Andryala L. (Asteraceae)

Andryala (Asteraceae: Cichorieae) is a little-known Mediterranean-Macaronesian genus whose taxonomy is much in need of revision. The aim of the present biosystematic study was to elucidate species relationships within this genus based on morphological and molecular data. In this study several taxa are recognised: 17 species, 14 subspecies, and 3 hybrids. Among these, 5 species are Macaronesian endemics (A. glandulosa, A. sparsiflora, A. crithmifolia Aiton, A. pinnatifida, and A. perezii), 4 species are Northwest African endemics (A. mogadorensis, A. maroccana, A. chevallieri, and A. nigricans) and one species is endemic to Romania (A. laevitomentosa). Historical background regarding taxonomic delimitation in the genus is addressed from Linnaean to present day concepts, as well as the origin of the name Andryala. The origin of Asteraceae and the systematic position of Andryala is shortly summarised. The morphological study was based on a bibliographic review and the revision of 1066 specimens of 13 herbaria as well as additional material collected during fieldwork. The variability of the morphological characters of the genus, including both vegetative taxonomic characters (root, stem, leaf and indumentum characters) and reproductive ones (inflorescence, floret, fruit and pappus characters), is assessed. Numerical analysis of the morphological data was performed using different similarity or dissimilarity measures and coefficients, as well as ordination and clustering methods. Results support the segregation of the recognised taxa and the congruence of the several analyses in the separation of the recognised taxa (using quantitative, binary or multi-state characters). The proposed taxonomy for Andryala includes a new infra-generic classification, new taxa and new combinations and ranks, typifications and diagnostic keys (one for the species and several for subspecies). For each taxon a list of synonyms, typification comments and a detailed description are provided, just as comments on taxonomy and nomenclature, and a brief discussion on karyology. Additionally, information on ecology and conservation status as well as on distribution and a list of studied material are also presented. Phylogenetic analyses based on different nuclear and chloroplast DNA markers, using Bayesian and maximum parsimony methods of inference, were performed. Results support three main lineages: separate ones for the relict species A. agardhii and A. laevitomentosa and a third including the majority of the Andryala species that underwent a relatively rapid and recent speciation. They also suggest a single colonization event of Madeira and the Canary Islands from the Mediterranean region, followed by insular speciation. Biogeography and speciation within the genus are briefly discussed, including a proposal for the centre of origin of the genus and possible dispersal routes.

The power of language and the language of power in M. T. Anderson’s Feed and Gary Stheyngart’s Super Sad True Love Story. A comparative analysis

The aim of my dissertation is to analyze how selected elements of language are addressed in two contemporary dystopias, Feed by M. T. Anderson (2002) and Super Sad True Love Story by Gary Shteyngart (2010). I chose these two novels because language plays a key role in both of them: both are primarily focused on the pervasiveness of technology, and on how the use/abuse of technology affects language in all its forms. In particular, I examine four key aspects of language: books, literacy, diary writing, as well as oral language. In order to analyze how the aforementioned elements of language are dealt with in Feed and Super Sad True Love Story, I consider how the same aspects of language are presented in a sample of classical dystopias selected as benchmarks: We by Yevgeny Zamyatin (1921), Brave New World by Aldous Huxley (1932), Animal Farm (1945) and Nineteen Eighty-Four (1949) by George Orwell, Fahrenheit 451 by Ray Bradbury (1952), and The Handmaid's Tale by Margaret Atwood (1986). In this way, I look at how language, books, literacy, and diaries are dealt with in Anderson’s Feed and in Shteyngart’s Super Sad True Love Story, both in comparison with the classical dystopias as well as with one another. This allows for an analysis of the similarities, as well as the differences, between the two novels. The comparative analysis carried out also takes into account the fact that the two contemporary dystopias have different target audiences: one is for young adults (Feed), whereas the other is for adults (Super Sad True Love Story). Consequently, I also consider whether further differences related to target readers affect differences in how language is dealt with. Preliminary findings indicate that, despite their different target audiences, the linguistic elements considered are addressed in the two novels in similar ways.

Ecosystem structure, function, and composition in rangelands are negatively affected by livestock grazing

Reports of positive or neutral effects of grazing on plant species richness have prompted calls for livestock grazing to be used as a tool for managing land for conservation. Grazing effects, however, are likely to vary among different response variables, types, and intensity of grazing, and across abiotic conditions. We aimed to examine how grazing affects ecosystem structure, function, and composition. We compiled a database of 7615 records reporting an effect of grazing by sheep and cattle on 278 biotic and abiotic response variables for published studies across Australia. Using these data, we derived three ecosystem measures based on structure, function, and composition, which were compared against six contrasts of grazing pressure, ranging from low to heavy, two different herbivores (sheep, cattle), and across three different climatic zones. Grazing reduced structure (by 35%), function (24%), and composition (10%). Structure and function (but not composition) declined more when grazed by sheep and cattle together than sheep alone. Grazing reduced plant biomass (40%), animal richness (15%), and plant and animal abundance, and plant and litter cover (25%), but had no effect on plant richness nor soil function. The negative effects of grazing on plant biomass, plant cover, and soil function were more pronounced in drier environments. Grazing effects on plant and animal richness and composition were constant, or even declined, with increasing aridity. Our study represents a comprehensive continental assessment of the implications of grazing for managing Australian rangelands. Grazing effects were largely negative, even at very low levels of grazing. Overall, our results suggest that livestock grazing in Australia is unlikely to produce positive outcomes for ecosystem structure, function, and composition or even as a blanket conservation tool unless reduction in specific response variables is an explicit management objective.
