Immature stages of the Selaginella-feeding Euptychia mollina(Nymphalidae: Satyrinae) from the Brazilian Amazon
The present paper describes the immature stages of the Neotropical satyrine butterfly Euptychia mollina (Hubner, [1813]) from the Brazilian Amazon Forest. Eggs were laid singly on the under surface of the fronds of its host plant, Selaginella sp. (Bryophyta: Selaginellaceae). Larvae are solitary in all instars, presenting a color pattern and shape that make them cryptic on its host plant. The pupa is short, smooth and varies from rusty brown to green. Despite the lack of a close phylogenetic relationship, larvae of Euptychia are very similar to those of the paleotropical satyrines Ragadia and Acrophtalmia, suggesting that camouflage is likely to be one of the factors explaining the similarities among them36CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTĂFICO E TECNOLĂGICO - CNPQCOORDENAĂĂO DE APERFEIĂOAMENTO DE PESSOAL DE NĂVEL SUPERIOR - CAPESFUNDAĂĂO DE AMPARO Ă PESQUISA DO ESTADO DE SĂO PAULO - FAPESP563332/2010-7; 302585/2011-7; 421248/2017-3sem informação2016/15873-8; 2011/50225-3This study was financed in part by the Coordenação de Aperfeiçoamento de Pessoal de NĂvel Superior (CAPES â Finance Code 001).

Mutualistic interactions shape global spatial congruence and climatic niche evolution in Neotropical mimetic butterflies
Understanding the mechanisms underlying species distributions and coexistence is both a priority and a challenge for biodiversity hotspots such as the Neotropics. Here, we highlight that Mullerian mimicry, where defended prey species display similar warning signals, is key to the maintenance of biodiversity in the c. 400 species of the Neotropical butterfly tribe Ithomiini (Nymphalidae: Danainae). We show that mimicry drives large-scale spatial association among phenotypically similar species, providing new empirical evidence for the validity of Muller's model at a macroecological scale. Additionally, we show that mimetic interactions drive the evolutionary convergence of species climatic niche, thereby strengthening the co-occurrence of co-mimetic species. This study provides new insights into the importance of mutualistic interactions in shaping both niche evolution and species assemblages at large spatial scales. Critically, in the context of climate change, our results highlight the vulnerability to extinction cascades of such adaptively assembled communities tied by positive interactions
Anthropogenic pressures coincide with Neotropical biodiversity hotspots in a flagship butterfly group
Aim The biodiversity crisis has highlighted the need to assess and map biodiversity in order to prioritize conservation efforts. Clearwing butterflies (tribe Ithomiini) have been proposed as biological indicators for habitat quality in Neotropical forests, which contain the world's richest biological communities. Here, we provide maps of different facets of Ithomiini diversity across the Neotropics to identify areas of evolutionary and ecological importance for conservation and evaluate their overlap with current anthropogenic threats. Location Neotropics. Methods We ran species distribution models on a data set based on 28,986 georeferenced occurrences representing 388 ithomiine species to generate maps of geographic rarity, taxonomic, phylogenetic and Mullerian mimetic wing pattern diversity. We quantified and mapped the overlap of diversity hotspots with areas threatened by or providing refuge from current anthropogenic pressures. Results The eastern slopes of the Andes formed the primary hotspot of taxonomic, phylogenetic and mimetic diversity, with secondary hotspots in Central America and the Atlantic Forest. Most diversity indices were strongly spatially correlated. Nevertheless, species-poor communities on the Pacific slopes of the Andes also sheltered some of the geographically rarest species. Overall, tropical montane forests that host high species and mimetic diversity as well as rare species and mimicry rings appeared particularly under threat. Main conclusions Remote parts of the Upper Amazon may act as refuges against current anthropogenic pressures for a limited portion of Ithomiini diversity. Furthermore, it is likely that the current threat status may worsen with ongoing climate change and deforestation. In this context, the tropical Andes occupy a crucial position as the primary hotspot for multiple facets of biodiversity for ithomiine butterflies, as they do for angiosperms, tetrapods and other insect taxa. Our results support the role of ithomiine butterflies as a suitable flagship indicator group for Neotropical butterfly diversity and reinforce the position of the tropical Andes as a flagship region for biodiversity conservation in general, and insect and butterfly conservation in particular
Frequência de polimorfismos responsåveis pela resistência a benzimidazóis em populaçþes de Haemonchus contortus do Cearå.
Haemonchus contortus ĂŠ o nematĂłide de maior prevalĂŞncia em pequenos ruminantes no Brasil. O seu controle tem sido realizado de forma indiscriminada com a utilização de anti-helmĂnticos de amplo espectro, o que inevitavelmente acelerou o desenvolvimento de resistĂŞncia anti-helmĂntica (RAH). Os benzimidazĂłis sĂŁo uma das classes mais utilizadas no estado do CearĂĄ, regiĂŁo Nordeste. Para diagnĂłstico de RAH tem sido utilizados apenas mĂŠtodos fenotĂpicos que apresentam baixa sensibilidade. Embora existam algumas tĂŠcnicas moleculares altamente sensĂveis de RAH, a maioria delas ĂŠ aplicĂĄvel apenas quando os polimorfismos de nucleotĂdeo Ăşnico (SNP) responsĂĄveis pela resistĂŞncia a benzimidazĂłis sĂŁo conhecidos. Dessa forma, o objetivo desse trabalho foi identificar e determinar a frequĂŞncia dos SNP responsĂĄveis pela resistĂŞncia a benzimidazĂłis em populaçþes de H. contortus isoladas no CearĂĄ. Para tanto, foram coletadas fezes em 19 propriedades de ovinos, uma por municĂpio, de modo que fossem contempladas todas as mesorregiĂľes do estado. Para extração de DNA foram utilizados em mĂŠdia 10.000 ovos, obtidos por tĂŠcnica de recuperação por meio de tamises. A identificação e quantificação da frequĂŞncia alĂŠlica dos SNP F167Y, E198A e F200Y do gene codificante para ?-tubulina foram realizadas por meio de PCR em tempo real quantitativa (qPCR) utilizando SYBR Green. As frequĂŞncias de alelos resistentes mĂŠdias para os SNP F167Y, E198A, F200Y foram de 62,31%, 0,02% e 33,65%, respectivamente. Os resultados sugerem que os SNP F167Y e F200Y sĂŁo importantes para a resistĂŞncia a benzimidazĂłis nas populaçþes estudadas e devem ser incluĂdos no diagnĂłstico molecular de RAH no CearĂĄ. AlĂŠm disso, o uso de ovos para o diagnĂłstico molecular pode ser uma boa ferramenta para uso em campo
Data standardization of plant-pollinator interactions
Background: Animal pollination is an important ecosystem function and service, ensuring both the integrity of natural systems and human well-being. Although many knowledge shortfalls remain, some high-quality data sets on biological interactions are now available. The development and adoption of standards for biodiversity data and metadata has promoted great advances in biological data sharing and aggregation, supporting large-scale studies and science-based public policies. However, these standards are currently not suitable to fully support interaction data sharing. Results: Here we present a vocabulary of terms and a data model for sharing plantâpollinator interactions data based on the Darwin Core standard. The vocabulary introduces 48 new terms targeting several aspects of plantâpollinator interactions and can be used to capture information from different approaches and scales. Additionally, we provide solutions for data serialization using RDF, XML, and DwC-Archives and recommendations of existing controlled vocabularies for some of the terms. Our contribution supports open access to standardized data on plantâpollinator interactions. Conclusions: The adoption of the vocabulary would facilitate data sharing to support studies ranging from the spatial and temporal distribution of interactions to the taxonomic, phenological, functional, and phylogenetic aspects of plantâpollinator interactions. We expect to fill data and knowledge gaps, thus further enabling scientific research on the ecology and evolution of plantâpollinator communities, biodiversity conservation, ecosystem services, and the development of public policies. The proposed data model is flexible and can be adapted for sharing other types of interactions data by developing discipline-specific vocabularies of terms.Fil: Salim, JosĂŠ A.

Data sources for drug utilization research in Latin American countriesâA cross-national study: DASDUR-LATAM study
Purpose: Drug utilization research (DUR) contributes to inform policymaking and to strengthen health systems. The availability of data sources is the first step for conducting DUR. However, documents that systematize these data sources in Latin American (LatAm) countries are not known. We compiled the potential data sources for DUR in the LatAm region. Methods: A network of DUR experts from nine LatAm countries was assembled and experts conducted: (i) a website search of the government, academic, and private health institutions; (ii) screening of eligible data sources, and (iii) liaising with national experts in pharmacoepidemiology (via an online survey). The data sources were characterized by accessibility, geographic granularity, setting, sector of the data, sources and type of the data. Descriptive analyses were performed. Results: We identified 125 data sources for DUR in nine LatAm countries. Thirty-eight (30%) of them were publicly and conveniently available; 89 (71%) were accessible with limitations, and 18 (14%) were not accessible or lacked clear rules for data access. From the 125 data sources, 76 (61%) were from the public sector only; 46 (37%) were from pharmacy records; 43 (34%) came from ambulatory settings and; 85 (68%) gave access to individual patient-level data. Conclusions: Although multiple sources for DUR are available in LatAm countries, the accessibility is a major challenge. The procedures for accessing DUR data should be transparent, feasible, affordable, and protocol-driven. This inventory could permit a comparison of drug utilization between countries identifying potential medication-related problems that need further exploration.Fil: Lopes, Luciane C..

Alignment of the CMS silicon tracker during commissioning with cosmic rays
This is the Pre-print version of the Article. The official published version of the Paper can be accessed from the link below - Copyright @ 2010 IOPThe CMS silicon tracker, consisting of 1440 silicon pixel and 15 148 silicon strip detector modules, has been aligned using more than three million cosmic ray charged particles, with additional information from optical surveys. The positions of the modules were determined with respect to cosmic ray trajectories to an average precision of 3â4 microns RMS in the barrel and 3â14 microns RMS in the endcap in the most sensitive coordinate. The results have been validated by several studies, including laser beam cross-checks, track fit self-consistency, track residuals in overlapping module regions, and track parameter resolution, and are compared with predictions obtained from simulation. Correlated systematic effects have been investigated. The track parameter resolutions obtained with this alignment are close to the design performance.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ,

Performance of the CMS drift-tube chamber local trigger with cosmic rays
The performance of the Local Trigger based on the drift-tube system of the CMS experiment has been studied using muons from cosmic ray events collected during the commissioning of the detector in 2008. The properties of the system are extensively tested and compared with the simulation. The effect of the random arrival time of the cosmic rays on the trigger performance is reported, and the results are compared with the design expectations for proton-proton collisions and with previous measurements obtained with muon beams
