Повний текст джерелаSpodoptera frugiperda é um dos principais insetos-praga do hemisfério ocidental, causando diversos danos a cultivos de interesse econômico, como milho e algodão. Uma das estratégias mais comuns de controle é o uso de plantas Bt, contudo sua aplicação intensa e indiscriminada levou à evolução de resistência em algumas populações. O estabelecimento de refúgio pode representar uma opção viável para atrasar esse processo. Refúgios são áreas nas quais cultivos não-Bt são plantados de forma a fornecerem insetos suscetíveis para a população. Neste estudo, eu desenvolvi inicialmente um modelo para descrever a evolução de resistência de populações de S. frugiperda em diferentes configurações de refúgio (mistura de sementes, blocos e faixas) e tamanhos (20 - 50%), considerando o movimento larval. Eu demonstrei que para a mistura de sementes, na maioria dos casos, maiores taxas de movimentação larval implicavam em maiores proporções de insetos resistentes na população, independente do tipo de resistência testada, enquanto áreas com configurações em faixas apresentaram tendência oposta. Na segunda parte deste trabalho, eu obtive dados para validar o modelo proposto. O desenvolvimento de S. frugiperda em folhas de milho foram determinadas em 5 temperaturas constantes variando de 14°C a 30°C. Estes dados também foram utilizados para estimar o número de gerações do inseto em 42 localizações no estado da Flórida de 2006 a 2016, que foram interpolados e representados em mapas, utilizando SIG (Sistema de Informações Geográficas). Eu observei que condados mais ao sul apresentaram maior número de gerações e que S. frugiperda é capaz de passar o inverno abaixo de latitudes ~29°N. Utilizando os dados obtidos no experimento, um novo modelo foi proposto, considerando um intervalo maior de condições e permitindo ao usuário definir a área de cultivo, as exigências térmicas da população estudada, as funções de oviposição e viabilidade, a taxa de migração, a taxa de movimentação larval e a frequência do alelo de resistência. O modelo foi verificado com dados de monitoramento de 2012 a 2015, coletados em uma área de cultivo localizada na Flórida, distante apenas 70 km da área que forneceu a população para o experimento laboratorial. Eu também utilizei o modelo para estimar o número de adultos para 2016 e para duas situações hipotéticas que consideraram possíveis cenários envolvendo o aquecimento global (médias de temperaturas de 2016 + 1°C e + 2°C). O modelo se ajustou aos dados de monitoramento com sucesso e indicou que os aumentos simulados na temperatura média poderiam produzir surtos quase duas vezes maiores que os níveis de S. frugiperda estimados para 2016. O modelo pode ser usado para estimar a dinâmica populacional de S. frugiperda em uma determinada área de acordo com a composição e disposição dos cultivos, investigar os efeitos das mudanças de temperatura nos níveis populacionais, definir áreas de refúgio apropriadas para o manejo da evolução de resistência, definir os melhores períodos para plantação e colheita durante o ano de forma a reduzir a população da praga, entre outros.

Resumo: Este trabalho teve como objetivo coletar dados de fatores de mortalidade que determinam a regulação populacional da lagarta-do-cartucho do milho e também avaliar a interferência de Telenomus remus neste processo. Durante a safra de 2009 (cultivos de 1ª e 2ª safras) blocos experimentais com e sem liberação de T. remus foram instalados. As fases de ovo e larva foram avaliadas separadamente. Plantas de milho foram infestadas artificialmente com massas de ovos e larvas obtidas de criação de laboratório. As avaliações consistiram no registro de ovos remanescentes, assim como as interações ecológicas por meio de macrofotografias. Amostragens destrutivas diárias foram realizadas para registrar o número de larvas remanescentes e coletar e quantificar os inimigos naturais presentes. A mortalidade de larvas de ínstares iniciais foi maior do que a mortalidade de ovos. A predação foi o principal fator biótico de mortalidade, predominante na 1ª safra. Doru luteipes (Dermaptera: Forficulidae) foi o predador mais importante. T. remus não parasitou ovos durante a 1ª safra e na 2ª safra, os níveis de parasitismo por este agente e a ocorrência natural de Trichogramma sp. (Hymenoptera: Trichogrammatidae) foram baixos. Predação por insetos herbívoros, tais como Diabrotica sp. (Coleoptera: Chrysomelidae) e Leptoglossus sp. (Hemiptera: Coreidae) foi registrada. Não foi observada predação em larvas, apesar da presença de Orius insidiosus (Hemiptera: Anthocoridae), um reconhecido predador de lagartas de primeiros ínstares. Este predador foi bastante abundante, principalmente durante a 2ª safra
Abstract: This work aimed to obtain data of mortality key-factors that determine the fall armyworm (FAW) population regulation and also to assess the impact of Telenomus remus on this regulation. During the 2009, experimental blocks were designed with and without releases of T. remus during two growing seasons. The egg and larval stages were evaluated separately. Maize plants were artificially infested using egg masses and larvae from the laboratory mass rearing. The evaluations consisted of recording the number of remaining eggs, as well as ecological interactions through macrophotography. Daily destructive sampling was carried out to record the number of remaining larvae as well as to collect and to quantify the natural enemies. The earlyinstar mortality was larger than egg mortality. The predation was the main mortality biotic factor and predominant in the first growing season. Doru luteipes (Dermaptera: Forficulidae) was the most abundant predator. T. remus did not parasitize any egg during the first growing season and the parasitism levels by this agent and naturally occurring Trichogramma sp. (Hymenoptera: Trichogrammatidae) were low on the second season. Predation by herbivorous insects such as Diabrotica sp. (Coleoptera: Chrysomelidae) and Leptoglossus sp. (Hemiptera: Coreidae) was recorded. It was not observed any predation on larvae, despite the presence of Orius insidiosus (Hemiptera: Anthocoridae), a recognized FAW early instars predator. This predator was very abundant mainly during the second season

Повний текст джерелаThe scalloped hammerhead shark Sphyrna lewini is one of the most valuable marine resources, due to its high-priced fins in the Asian market, which can reach U$ 100,00/kg. The analysis of the length and age composition in the catches, growth studies, and the annual development of its landings in southern Brazil, showed signs of overexploitation for the species. This effect was mainly caused by different fishing gears exploiting all the phases of its life-cycle and its low resilience to fishing pressure due to its slow-growing strategy (L∞ = 329,12 cm; K = 0,071 yr-1; to = -2,37 ano; both sexes), longevity (> 40 yrs.) and low natural mortality (M = 0,1 yr-1, during adult phase), which means a K\'strategic typical pattern. Recruitment overfishing use to happen in coastal areas by trawls and anchored gillnets activities which destroy the nurseries and juvenile grounds for the species, mainly in spring-summer months when the parturition occurs. On the other hand, the adult fraction of the stock is reduced by surface longline and driftnets activities along the continental slope. For the surface monofilament longline fisheries, covariance models detected the highest catches of scalloped hammerhead sharks along the slope (between 200 - 3000 m depth), during spring-summer months. There was also a positive linear relationship between catch (in weight) and effort (hook number). Management and conservation measures are recommended for this species.

Повний текст джерелаThis study has shown that the natural establishment of tree species in the understory of abandoned Eucalyptus plantation for 13 years was not affected. For the quantification of the regeneration process, this study addressed the following objectives: study the floristic composition, vegetation structure and other aspects of vegetation dynamics of a tropical rain forest fragments, defined as: A1 area, which was compared with another area where native regeneration is happening in the understory of abandoned E. saligna., for 13 year, defined as A2. Ten permanent plots of 10 x 20m in each area were located, where analysis of floristic composition, phytosociology, seed rain and light intensity were conducted. Soil samples were also collected for fertility analysis. The results have shown an occurrence of 95 species from 31 families in A1 area, being 59 endemic species to this site. In the A2 area, 53 species of 25 families were found, being 17 endemic to this site. Similarity index was 32%. The results allow the classification of the A1 area as intermediate to advance stage of regeneration, while the A2 area is of early stage. The removal of Eucalyptus trees could also enhance the natural regeneration of the A2 area, and speeding the process up.

Повний текст джерелаThis work aimed to evaluate the effect of three fallow systems in natural regeneration dynamics, structure and diversity in an abandoned plantation of Eucalyptus saligna Smith. Our study was carried out in the Itatinga Experimental Station of the University of São Paulo - USP, located in the county of Itatinga-SP, Brazil. The plantation has been abandoned for approximately 40 years; however, remaining E. saligna individuals were removed two years before our study under different harvesting systems. We used the randomized blocks design to sample 3.24 hectares in the study area. For each treatment, we placed three 30 x 30 m plots in each block totaling nine plots per treatment and a sampling area of 0.81 hectares per treatment. We sampled all E. saligna individuals, as well as natural regeneration with height >= 1.3 m and DBH >= 5,0 cm. In 3 x 3 m subplots we counted and tagged all individuals with height >= 5 cm and DBH < 5,0 cm. In the Control plots we found 278 individuals of E. saligna, which represents a density of 343.21 individuals/hectare. Total estimated wood volume of E. saligna was of 438,72 m3.ha-1, with a basal area of 23,18 m2.ha-1. In the 36 plots we sampled 1910 individuals, distributed in 168 species, 78 genus and 39 families. Natural regeneration density was of 589.51 individuals/hectare for individuals DBH > 5.0 cm and 11.080 individuals/hectare for individuals DBH < 5.0 cm and height >= 0.5 m. We studied the effect of fallow system in the vegetation structure considering four classes of damage to natural regeneration: intact, damaged, resprouted and dead. Our study shows that there was no significant difference between Conventional and Reduced Impact Logging 2 systems. The Reduced Impact Logging 1 and Control plots showed higher proportion of intact trees (57.89 % and 93.83 %, respectively), however, these treatments differed among each other. Control plots showed the lowest proportion of dead trees, followed by Reduced Impact Logging 1 (4.23 % and 16.98 %, respectively). We evaluated diversity of native individuals with DBH >= 5.0 cm through the Shannon diversity index (H\'), species richness (S) and Pielou equability (J\'). We calculated the dynamic rates ofmortality, recruitment, change in basal area, turnover and net change rates during the study period. Removal of planted E. saligna increased recruitment when compared to Control plots, however species diversity was higher in Control plots. Control plots were the only treatment that showed significant differences between the Shannon diversity Index and richness for the study period (i.e. right after logging and 24 months after logging).

Повний текст джерелаBackground: Due to the rapid development and application of next generation sequencing (NGS) techniques, large amounts of NGS data have become available for genome-related biological research, such as population genetics, evolutionary research, and genome wide association studies. A crucial step of these genome-related studies is the detection of genomic variation between different species and individuals. Current approaches for the detection of genomic variation can be classified into alignment-based variation detection and assembly-based variation detection. Due to the limitation of current NGS read length, alignment-based variation detection remains the mainstream approach. The Smith-Waterman algorithm, which produces the optimal pairwise alignment between two sequences, is frequently used as a key component of fast heuristic read mapping and variation detection tools for next-generation sequencing data. Though various fast Smith-Waterman implementations are developed, they are either designed as monolithic protein database searching tools, which do not return detailed alignment, or they are embedded into other tools. These issues make reusing these efficient Smith-Waterman implementations impractical. After the alignment step in the traditional variation detection pipeline, the afterward variation detection using pileup data and the Bayesian model is also facing great challenges especially from low-complexity genomic regions. Sequencing errors and misalignment problems still influence variation detection (especially INDEL detection) a lot. The accuracy of genomic variation detection still needs to be improved, especially when we work on low- complexity genomic regions and low-quality sequencing data. Results: To facilitate easy integration of the fast Single-Instruction-Multiple-Data Smith-Waterman algorithm into third-party software, we wrote a C/C++ library, which extends Farrar's Striped Smith-Waterman (SSW) to return alignment information in addition to the optimal Smith-Waterman score. In this library we developed a new method to generate the full optimal alignment results and a suboptimal score in linear space at little cost of efficiency. This improvement makes the fast Single-Instruction-Multiple-Data Smith-Waterman become really useful in genomic applications. SSW is available both as a C/C++ software library, as well as a stand-alone alignment tool at: https://github.com/mengyao/Complete- Striped-Smith-Waterman-Library. The SSW library has been used in the primary read mapping tool MOSAIK, the split-read mapping program SCISSORS, the MEI detector TAN- GRAM, and the read-overlap graph generation program RZMBLR. The speeds of the mentioned software are improved significantly by replacing their ordinary Smith-Waterman or banded Smith-Waterman module with the SSW Library. To improve the accuracy of genomic variation detection, especially in low-complexity genomic regions and on low-quality sequencing data, we developed PHV, a genomic variation detection tool based on the profile hidden Markov model. PHV also demonstrates a novel PHMM application in the genomic research field. The banded PHMM algorithms used in PHV make it a very fast whole-genome variation detection tool based on the HMM method. The comparison of PHV to GATK, Samtools and Freebayes for detecting variation from both simulated data and real data shows PHV has good potential for dealing with sequencing errors and misalignments. PHV also successfully detects a 49 bp long deletion that is totally misaligned by the mapping tool, and neglected by GATK and Samtools. Conclusion: The efforts made in this thesis are very meaningful for methodology development in studies of genomic variation detection. The two novel algorithms stated here will also inspire future work in NGS data analysis

Повний текст джерелаThis work was divided into three parts focusing two main topics: the study of volatiles compouds of P. graveolens and the study of the essential oil of L. alba and its evaluation of insecticidal activity against Spodoptera frugiperda. The chapter 2 approuch the study of the volatile compounds of the leaves of P. graveolens extracted by dynamic headspace using Porapak Q® as adsorbent and in nature peat, a novel adsorbent in the extraction of plant volatiles, and the results were compared with those obtained by hidrodestilation. The results showed that hydrodistilation (HD) was more efficient for extracting linalool and citronellyl formate. While citroneol, geraniol and geranyl tiglate were obtained in greater quantity by dynamic headspace using in nature peat (HSD-T), isomenthone, 6,9- guaiadiene and - muurolene by headspace using Porapak Q® (HSD-P). The study of conversion proved that geraniol converts in linalool when geraniol is subjected to water vapor and high temperature, nevertheless a small ratio. This also prove, in parts, the high percentage of linalool obtained by HD compared to HSD-T and HSD-P. The chapter 3 approuch the study of the essential oils of 9 accessions of L. alba collected in 4 states of Brazil using statistical methods and checking the accessions with the best essential oil content. The statistical methods of hierarchical cluster analysis (HCA) and Principal component analysis (PCA) were used to prove the experimental data and confirmation of training groups. Three groups representatives of the three chemotypes were formed: Group I was characterized by linalool and 1,8-cineole; group II, by limonene and carvone; and group III by neral and geranial. In chapter 4 was approached the evaluation of insecticidal activity of the essential oils of P. graveolens (PEL-001) and L. alba (accessions LA-10, LA-22 and LA-57) and also of the main compounds (geraniol, linalool, 1,8-cineole, limonene, carvone) against S. frugiperda via topical aplication. The test of topical application showed that the essential oils of P. graveolens (PEL-001) and L. alba (accessions LA-10, LA-22, LA-57) showed acute toxicity against larvae of S. frugiperda, causing mortality of up to 100% at a dose 192 μg/larvae.
O presente trabalho foi dividido em 3 partes os quais abordam 2 temas centrais: estudo dos compostos voláteis de Pelargonium graveolens e do óleo essencial de Lippia alba e avaliação de atividade inseticida frente à Spodoptera frugiperda. O capítulo 2 abordou o estudo dos voláteis das folhas de P. graveolens extraídos por headspace dinâmico utlizando Porapak Q® como adsorvente e turfa in natura, um adsorvente inédito empregado na extração de voláteis de plantas, sendo os resultados comparados com àqueles obtidos por hidrodestilação. Os resultados mostraram que a hidrodestilação (HD) foi mais eficiente na extração de linalol e formiato de citronelila. Enquanto citronelol, geraniol e tiglato de citronelila foram obtidos em maior proporção por headspace dinâmico utilizando turfa in natura como adsorvente (HSD-T), isomentona, 6,9- guaiadieno e -muuroleno foram identificados em maior proporção por headspace dinâmico utilizando Porapak Q® (HSD-P). O estudo de conversão comprovou que geraniol se converte em linalol, quando o geraniol é submetido a vapor d água e altas temperaturas, porém a um pequeno percentual. Isso também comprova, em partes, o alto percentual de linalol obtido por HD em relação à HSD-T e HSD-P. A extração do hidrolato revelou variações na composição volátil em comparação com os outros métodos de extração. O Capítulo 3 abordou o estudo dos óleos essenciais de 9 acessos de L. alba coletados em 4 estados do Brasil empregando métodos estatísticos e verificando os acessos com melhores teor de óleo essencial. Os métodos estatísticos de análise hierárquica de agrupamentos (HCA) e análise de componentes principais (PCA) foram empregados para comprovar os dados experimentais e confirmar a formação dos grupos. Três grupos, representando os três quimiotipos, foram formados, dos quais o grupo I foi caracterizado por linalol e 1,8-cineol, grupo II por limoneno e carvona e grupo III por neral e geranial. No capítulo 4 foi abordado a avaliação de atividade inseticida dos óleos essenciais de P. graveolens (PEL-001) e L. alba (acessos LA-10, LA-22 e LA-57), bem como dos seus principais compostos majoritários (geraniol, linalol, 1,8-cineol, limoneno e carvona) frente à S. VII frugiperda. O ensaio de aplicação tópica mostrou que óleos essenciais de P. graveolens (PEL-001) e L. alba (acessos LA-10, LA-22, LA-57) apresentaram toxicidade aguda nas lagartas S. frugiperda, ocasionando mortalidade de até 100% na dose 192 μg/lagarta.

Current implementations of sequence alignment methods based on Smith- Waterman and Levenshtein distance have proven to be computationally intensive and, hence, amenable for hardware acceleration. This Msc. Thesis describes an FPGA and ASIC based hardware implementation designed to accelerate the Smith-Waterman and Levenshtein distance maintaining the same results yielded by general softwares. We describe an new efficient Smith-Waterman affine gap process element and a new architecture to partitioning and maping the Levenshtein distance into fixed size systolic arrays. Our FPGA Smith-Waterman implementation delivers 275 to 494-fold speed-up over a standard desktop computer and is also about 52 to 113% faster, to the best of our knowledge, than the fastest implementation in a most recent family of accelerators.

Повний текст джерелаTransport of waves plays an important role in modern communication systems like Wi-Fi or optical fibres. Typical problems in such systems concern security against possible intruders, energy consumption, time efficiency and the possibility of mode filtering. Microwave experiments are suited to study this kind of problems, because they offer a good control of the experimental parameters. Thus we can implement the method of wave shaping to investigate atypical transport phenomena, which address the mentioned problems. Wave front shaping solely based on the transmission together with the Wigner-Smith time delay formalism allows me to establish special scattering states in situ. These scattering states avoid a pre-selected region, focus on a specific spot or follow trajectories of classical particles, so called particle-like scattering states. Mode filtering is induced inside a waveguide with wavy boundaries and position dependent loss. The boundary profiles are chosen in such a way that the two propagating modes describe an encircling of an exceptional point in the Bloch picture. The asymmetric mode filtering is found due to the appearing non-adiabatic transitions. Another part of my work deals with Grover’s quantum search. I put such a search into practice in a two-dimensional graphene-lattice using coupled resonators, which form a tight-binding analogue. In this proof of principle experiment we search for different resonators attached to the graphene-lattice. Furthermore, the scaling behaviour of the quantum search is quantified for a linear chain of resonators

"This thesis extends and summarises Australian data on carp (Cyprinus carpio L.) reproductive biology and early growth. Specifically, it (1) validates the aging of larval and early-juveniles via daily otolith increment counts, (2) provides regression equations to account for shrinkage that occurs upon preservation of young-of-the-year (YOY) carp in 70 and 95% ethanol, (3-4) investigates the timing, frequency and duration of spawning via gonad staging and via a combination of gonad staging and YOY sampling, and (5) investigates relationships between YOY recruitment and nine hydro-climatic parameters, and examines spatial and temporal variation in YOY growth."

As in the real society, the government often uses the news media to announce thefuture monetary policy, but at the same time, government does not explain explicitly tothe people on the scope of quantity margin increased; or, due to the poor credit that theformer government has, which creates the result of some people does not believe andsome does during the announcement; or, prior to the election, candidate made promise toexecute loose monetary policy, however, the probability of being elected will not equal to1. All of these policies announcement are a sign of uncertainty phenomenon.Consequently , this article will consider these policy facts into account. Also, in referenceto Dornbusch (1976) and Wilson (1979), there were no government taxation concept intheir article. However, in real society, the source of government expenditures is mainlycomes from the government tax revenue. At the same time when government increasestheir expenditures, they often require to increase the taxation to cover. Therefore, thisarticle also considered government taxation and balanced budget of government, andHolmes-Smyth effect would also be taken into account at the same time (it is going toextend the model assumption of Dornbusch (1976)) so as to construct the economicmodel that both outputs and prices could be changeable. Based on this model, one couldstudy the influence of currency policy announcement towards economic system. The main findings of this research are as follows. First, this is neutrality of money inthe long-run. Secondly, the government announced the range of currency suppliesincrease and the economic have the jump phenomenon when populace face theuncertainty currency supplies increase, When policy execution, the economic system has the jump phenomenon again.

This article was based on the models developed by Dornbusch (1976) and Chang and Lai (1997), taking government's balanced budget and the Holmes-Smyth effect into our development for the function of aggregate supply to evaluate the dynamic changes to exchange rates, price levels and the long run equilibrium of our economy following an anticipated expansionary fiscal policy. We discovered that: the higher the multiple between income elasticity of money supply and price elasticity of trade, the more the exchange rate of an economy strengthens rapidly before the announcement of the policy. The shorter the time between policy announcement and policy execution, the more likely the exchange rate will overshooting; on the contrary the longer the time between policy announcement and policy execution, the more likely the exchange rate will undershooting. In other words, the timing between policy announcement and execution determines the short-term exchange rate volatility. In this thesis we conducted a Johansen cointegration test on the USD/NTD exchange rate, consumer price index, and government spending statistics between the period from July 1986 to January 2008; we found that cointegration existed between these three variables, implying a long term relationships between them. Consumer price and government spending were significantly positively correlated, which was consistent with the conclusion of our theory. Exchange rate and government spending were also significantly positively correlated; this result was different from the conclusion derived from Dournbusch's model (1976), suggesting the possible existence of the Holmes-Smyth effect. Finally, we concluded from Granger's causality test (1988) that: there is a significant one-way Granger causality from government to the exchange rate; there is also a significant one-way Granger causality from the consumer price to the exchange rate, and a significant one-way Granger causality from the consumer price to the government.

Abstract This paper presents a macroeconomic uncertainty policy increment of intertemporal policy mix announcement model of flexible price and fixed output in a closed economy based on the framework developed by Tseng(2011), Liaw and Tseng(2012). We use the announcement effect approach of rational expectation to discover the influence of stock price dynamic adjustment pattern under the increment uncertainty of intertemporal policy mix? The major findings are (1) whether the actual policy increment of the policy authorities is different from the expectation of the public? (2) the relative magnitude of “the liquidity effect” and “the dividend effect”, (3) the relative magnitude of “the liquidity effect” and the sum of “the dividend effect” and “the Holmes-Smyth effect”, (4) the relative magnitude of the “the policy increment effect between fiscal and monetary policy”, (5) the relative magnitude of the “the policy announcement effect between fiscal and monetary policy” are the key determinants to decide the stock price dynamic adjustment pattern.
