Systemic Analysis of the Soccer (Football) Value Chain: Learning from the Brazilian Context

Soccer (football) is identified as the most popular sport in the world with a high turnover of economic-financial resources. The different segments of the soccer (football) value chain exert mutual influence on the variables that rule the dynamics of this sector. In this sense it is necessary to identify the variables that represent the soccer (football) value chain systemically; to understand the interrelationships between these variables, the main difficulties derived from this interrelationship and to point out variables that require actions to increment the results of the soccer (football) value chain as a whole. Hence, this study applied a semi-structured questionnaire with open-ended questions about the problems and leveraging variables that exist in this sports modality. A causal linkage diagram was elaborated based on the answers to the interviews, showing the systemic structure of the soccer (football) value chain in Brazil, whose premise it is to identify the existing circularities and the possibly existing points of leverage. The systemic structure pointed to the economic participation of soccer (football) in the Gross Domestic Product as a central variable to be leveraged, which tends to synthetize the results of the joint action of the actors in this chain. Furthermore, the variables that may limit or amplify the growth were identified. The systemic structure showed that the soccer (football) commodity chain is complex because of the great number of variables and interrelationships needed to represent its dynamics. The relationship between the actors also proved to be a factor of impact on economic and social development.     

Faunistic analysis of Cerambycidae (Insecta: Coleoptera) in an area of Atlantic Forest

The Atlantic Forest is considered a hotspot biome, one of the most diverse in the world. Currently, due to deforestation, only 22% of the original cover remains, and only 7.5% well preserved. Despite the global importance of this biome, it still lacks basic studies, e.g. primary inventories. Cerambycidae is one of the most diverse groups of beetles, with high ecological and economic importance. The aim of this work was to survey the longhorn beetles (Cerambycidae) in three fragments (Pacangê, Vila 5 and Pancada Grande) of Atlantic Forest within Reserva Ecológica da Michelin (southern Bahia State, Brazil). A total of 166 individuals belonging to 53 species were recorded, 15 of them new geographical records for the state, and one for Brazil. The Shannon index (H) shows Pacangê (H = 2.665) as the most diverse fragment, followed by Pancada Grande (H = 2.658) and Vila 5 (H = 2.565). The most abundant species were Nyssodrysina lignaria (38 specimens collected), followed by Compsibidion vanum (31 specimens). One hundred and ten specimens were captured in Malaise traps, while in light traps only 56 specimens were caught; however, the richness and consequently the diversity in light traps was higher. This is one of the few studies carried out in Atlantic Forest surveying longhorn beetles, and provides primary data on these taxa, to help develop conservation policies for this threatened biome.     

Heterotrophic plasticity and resilience in bleached corals

Mass coral bleaching events caused by elevated seawater temperatures have resulted in extensive coral mortality throughout the tropics over the past few decades. With continued global warming, bleaching events are predicted to increase in frequency and severity, causing up to 60% coral mortality globally within the next few decades. Although some corals are able to recover and to survive bleaching, the mechanisms underlying such resilience are poorly understood. Here we show that the coral host has a significant role in recovery and resilience. Bleached and recovering Montipora capitata (branching) corals met more than 100% of their daily metabolic energy requirements by markedly increasing their feeding rates and CHAR (per cent contribution of heterotrophically acquired carbon to daily animal respiration), whereas Porites compressa (branching) and Porites lobata (mounding) corals did not. These findings suggest that coral species with high-CHAR capability during bleaching and recovery, irrespective of morphology, will be more resilient to bleaching events over the long term, could become the dominant coral species on reefs, and may help to safeguard affected reefs from potential local and global extinction.     

Transcriptome analysis of the acoelomate human parasite Schistosoma mansoni

Schistosoma mansoni is the primary causative agent of schistosomiasis, which affects 200 million individuals in 74 countries. We generated 163,000 expressed-sequence tags (ESTs) from normalized cDNA libraries from six selected developmental stages of the parasite, resulting in 31,000 assembled sequences and 92% sampling of an estimated 14,000 gene complement. By analyzing automated Gene Ontology assignments, we provide a detailed view of important S. mansoni biological systems, including characterization of metazoa-specific and eukarya-conserved genes. Phylogenetic analysis suggests an early divergence from other metazoa. The data set provides insights into the molecular mechanisms of tissue organization, development, signaling, sexual dimorphism, host interactions and immune evasion and identifies novel proteins to be investigated as vaccine candidates and potential drug targets.     

The European dimension for the mouse genome mutagenesis program

The European Mouse Mutagenesis Consortium is the European initiative contributing to the international effort on functional annotation of the mouse genome. Its objectives are to establish and integrate mutagenesis platforms, gene expression resources, phenotyping units, storage and distribution centers and bioinformatics resources. The combined efforts will accelerate our understanding of gene function and of human health and disease.
