Abstract:
AbstractForensically important flesh flies (Diptera: Sarcophagidae) often are not morphologically distinguishable, especially at the immature stage. In addition, female flies are quite similar in general morphology, making accurate identifications difficult. DNA-based technologies, particularly mitochondrial DNA (mtDNA), have been used for species-level identification. The cytochrome oxidase subunits I and II (COI-COII) sequences of Iranian Sarcophagidae are still unavailable in GenBank. In this study as many as 648 (540 males and 106 females) fly specimens from family Sarcophagidae, representing 10 sarcophagid species, including eight forensically important species were collected from seven locations in five Iranian provinces. Of these, 150 male specimens were identified based on both morphology of male genitalia and DNA sequencing analysis. Sequence data from the COI-COII regions for 10 flesh fly species collected in Iran were generated for the first time. Digestion of COI-COII region by restriction enzymes RsaI, EcoRV, and HinfI provided distinct restriction fragment length polymorphism profiles among the species and can serve as molecular markers for species determination. Phylogenetic analysis represented that the COI-COII sequences are helpful for delimitation of sarcophagid species and implementation in forensic entomology. However, the application of the COI-COII fragment as a species identifier requires great caution and additional species and markers should be studied to ensure accurate species identification in the future.

Abstract:
The function of individual genes of the Bacillus megaterium cobI operon genes in cobalamin (vitamin B12) biosynthesis was investigated by their ability to complement defined Salmonella typhimurium cob mutants. This strategy confirmed the role of cbiA, -D, -F, -J, -L and cysGA. Furthermore the operon as a whole was used to restore corrin biosynthesis in Escherichia coli, which, although closely related to S. typhimurium, does not possess the CobI pathway. When the B. megaterium cob operon was cloned into a plasmid and transformed into an E. coli strain containing the S. typhimurium cbiP, it conferred upon the host strain the ability to make the cobyric acid de novo. However, cobyric acid synthesis was observed only when the strain was grown anaerobically. Derivatives of the corrin-producing E. coli strain were constructed in which genes of the B. megaterium cob operon had been inactivated. These strains were used to demonstrate that, whereas B. megaterium cbiD, -G and -X are essential for cobyric acid synthesis, the cbiW and -Y genes could be deleted without detriment to cobyric acid production in E. coli.

Abstract:
Over the last few decades, molecular markers have been extensively used to study phylogeny, population dynamics, and genome mapping in insects and other taxa. Phylogenetic methods using DNA markers are inexpensive, fast and simple to use, and may help greatly to resolve phylogenetic relationships in groups with problematic taxonomy. However, different markers have various levels of phylogenetic resolution, and it's important to choose the right set of molecular markers for a studied taxonomy level. Acrididae is the most diverse family of grasshoppers. Many attempts to resolve the phylogenetic relationships within it did not result in a clear picture, partially because of the limited number of molecular markers used. We have tested a phylogenetic resolution of three sets of the most commonly utilized mitochondrial molecular markers available for Acrididae sequences in the database: (i) complete protein-coding mitochondrial sequences, (ii) concatenated mitochondrial genes COI, COII, and Cytb, and (iii) concatenated mitochondrial genes COI and COII. We then complemented the analysis by testing the nuclear ITS2 region. Adequate phylogenetic resolution of Acrididae subfamilies can be achieved using three (COI, COII, and Cytb) or more mitochondrial markers. Moreover, we found the ITS2 and concatenated COI/COII markers to be the least informative, providing a poor resolution. All the studied acridids fall into three well-supported phylogenetic groups that include 13 subfamilies. Acridinae, Gomphocerinae, Oedipodinae, and Catantopinae are shown to be polyphyletic, while the remaining subfamilies are in accordance with current Acrididae systematics. Our study provides a basis for more comprehensive phylogenetic analyses of Acrididae on the subfamily and lower levels.

Abstract:
Proton reduction by [CoII(BPyPy2COH)(OH2)2]2+ (BPyPy2COH = [2,2'-bipyridin]-6-yl-di[pyridin-2-yl]methanol) proceeds through two distinct, pH-dependent pathways involving proton-coupled electron transfer (PCET), reduction and protonation steps. In this account we give an overview of the key mechanistic aspects in aqueous solution from pH 3 to 10, based on electrochemical data, time-resolved spectroscopy and ab initio molecular dynamics simulations of the key catalytic intermediates. In the acidic pH branch, a PCET to give a CoIII hydride is followed by a reduction and a protonation step, to close the catalytic cycle. At elevated pH, a reduction to CoI is observed, followed by a PCET to a CoII hydride, and the catalytic cycle is closed by a slow protonation step. In our simulation, both CoI and CoII–H feature a strong interaction with the surrounding solvent via hydrogen bonding, which is expected to foster the following catalytic step.

Abstract:
Abstract A new infestation of the Formosan subterranean termite, Coptotermes formosanus Shiraki (Blattodea: Rhinotermitidae), was discovered in Canyon Lake, Riverside County, California. We used three mitochondrial DNA (COI, COII, and 16S) and seven polymorphic microsatellite markers to characterize the genetic relationship of the colony with two other colonies that were collected in 1992 and 2018 in La Mesa, San Diego County. Maximum likelihood phylogeny of C. formosanus based on concatenated COI and COII sequences revealed that the two La Mesa populations (CA01 and CA02) and the Canyon Lake population (CA03) were from different maternal lineages. Based on the 14 COII haplotypes of C. formosanus found world-wide, CA01 and CA02 belonged to a haplotype widely distributed across the United States, while CA03 was grouped under a haplotype predominantly found in Asia. Microsatellite allele frequencies across all loci for both La Mesa populations were relatively similar, but significant genetic differences were found between CA02 and CA03 colonies (FST = 0.24; Dest = 0.30; G″ ST = 0.55; P < 0.01).

Abstract:
Bis ( ligand )cobalt(III/II) complexes of the tripodal π-acceptor ligands Py3X ( Py = 2-pyridyl; X = N, CH, COH, P, P=O) have been synthesized and characterized. Electrochemical studies in acetonitrile (or propylene carbonate) solution reveal the CoIII/CoII and CoII/CoI redox couples for all complexes on the cyclic voltammetric time scale; coulometry studies show the CoI species for X = CH, P, P=O have long-term stability, while for X = N, COH the analogous complexes may be observed but are not sustained for such long periods (i.e. minutes or hours in the last two cases). Aspects relating to the stabilization of the CoI state by these ligands are discussed. Preliminary studies on the reactivity of the bis(ligand)cobalt(I) species (X = CH, P) with water and HCO3- are also reported: water undergoes reduction to H2 but no reduction of HCO3- occurs. In the water reduction reaction involving the complex with X = P, ligand dissociation does not occur, in contrast to the case for X = CH and for the analogous reaction of [Co( bpy )3]+.

Abstract:
In Mexico, wastewater recycling is an important alternative source of water, particularly in arid regions like the state of Sonora, Mexico. In El Valle del Yaqui, Sonora, Mexico, where 500 million m3 per year of wastewater is available for recycling in agriculture activities . The main objective of the three studies presented in this dissertation was to assess the microbial water quality of surface water, untreated wastewater, and treated wastewater for produce irrigation, as well as the impact of microbial water quality on vegetable contamination. The results suggest that the three sources of water meet Mexican and international guidelines for use in production of food crops.Despite wide differences in the concentration of bacterial indicators (Escherichia coli, Clostridium perfringens) and enteric pathogens (Cryptosporidium, Giardia, and enteroviruses) in the various types of water studied there was little impact on contamination of the produce studied (carrots, lettuce, tomatoes, and peppers) at harvest. Apparently, the time between the last irrigation event and harvesting was sufficient to allow for die-off of enteric organisms that may have contaminated the produce.

The epoch of Pleistocene was marked by grate climate and flora alterations. On the southern hemisphere, where the glaciations had less intensity, there was the formation of refuges, providing a favorable condition to speciation. The genus Zygothrica (Diptera: Drosophilidae) is characterized by their interaction with fungi. Zygothrica vittimaculosa is considered a generalist species, because it explores even fungi, flowers (genus Cestrum, Solanaceae) and rotting fruits. In this work we identified a new species that is cryptic with Z. vittimaculosa and they are simpatric in almost all distribution area. However, this new species is rarely collected in resources but Cestrum inflorescences, differently of Z. vittimaculosa. Only after molecular analyses we realize it was a new species (posteriorly confirmed by male internal genitalia analyses), due to the external morphology of both species is identical. Also in this work we did the taxonomic description of this new species. A comparative analysis was performed by photographs, with the documentation of the external patterns (morphology and color) and the internal genitalia morphology (considered diagnostic) for both females and males, in addition to a measures table. Finally, was also performed a phylogeographic study based on two mitochondrial markers: COI (Citochrome c Subunit I) and COII (Citochrome c Subunit II). In this case, through collections and climate variables data, we estimate the present distribution of both species as well as an estimated of the Last Glacial Maximum distribution (about 20,000 years), suggesting that the potential distribution of both species seems to be restricted to the already sampled area, besides pointed a high suitability in northern Peru and western Chile for the new species, data not inferred to Z. vittimaculosa. About phylogeographic patterns, we suggest that, through Neutrality tests and Diversity indexes, the newest species had a really recent expansion, and potentially is also in diversification and expansion, while Z. vittimaculosa, despite also presents population expansion signals, these are less intense than their sister-species. To explain this inference, we can assume that because Z. vittimaculosa be more generalist than the other species, it had suffered more selection pressure, diversifying and increasing the number of haplotypes.
A época do Pleistoceno foi marcada por grandes alterações na vegetação e principalmente no clima. No Hemisfério Sul, as glaciações foram menos intensas, onde houve também a formação de refúgios, proporcionando uma condição favorável à especiações. O gênero Zygothrica, pertencente à família Drosophilidae, é característico por sua interação com fungos. Zygothrica vittimaculosa é uma espécie considerado um tanto generalista, por explorar recursos diversos: inflorescências do gênero Cestrum, corpos de frutificação de fungos e frutas em decomposição. Neste trabalho, identificamos uma nova espécie, críptica com Z. vittimaculosa e simpátrica em boa parte de sua distribuição. Porém essa espécie nova é raramente amostrada em outros recursos além de inflorescências de Cestrm, diferentemente de Z. vittimaculosa. De morfologia externa idêntica à de Z. vittimaculosa, apenas após análises moleculares percebeu-se indícios de se tratar de uma espécie nova, confirmada, posteriormente, pela morfologia interna da genitália dos machos. Também nesse trabalho fez-se a descrição taxonômica da nova espécie. Uma análise comparativa com Z. vittimaculosa foi feita e documentada através de fotos de hábitos da morfologia externa e das genitálias, consideradas diagnósticas tanto para machos quanto para femeas, além de uma tabela com as medias taxonômicas. Por fim, foi também performado um estudo filogeográfico com base em dois marcadores moleculares: COI (Citocromo c subunidade I) e COII (Citocromo c subunidade II). Nesse estudo, com base em dados de coletas e dados de variáveis climáticas estimou-se a distribuição atual de ambas as espécies e também a estimativa da distribuição no último máximo glacial (há cerca de 20.000 anos), sugerindo que a distribuição potencial de ambas restringe-se à área de estudo já amostrada, além de apontar uma alta adequabilidade para a espécie nova norte do Peru e no oeste do Chile, que não foram recuperadas para Z. vittimaculosa. Quanto aos padrões filogeográficos, sugere-se que, através de testes de neutralidade e índices de diversidade, a espécie nova teve uma expansão muito recente e potencialmente ainda está se expandindo e diversificando, enquanto Z. vittimaculosa, apesar de apresentar indicativos de expansão populacional também, esse são menos intensos que a de sua espécie irmã. Para esse explicar esse fato, pode-se supor que por Z. vittimaculosa ser mais generalista que a outra espécie, sofreu mais pressões de seleção, diversificando-se e aumentando o número de haplótipos.

The Quaternary period was marked by considerable changes on climate and vegetation. In the Southern Hemisphere, glaciations were milder than in the Northern Hemisphere, however, there were temperature reductions, and the climate became drier. Thus, climate-related modifications occurred in the Atlantic forest vegetation, which contracted its distribution being substituted towards other types, such as Cerrado and Caatinga . The original Atlantic forest vegetation became restricted to moist locations with milder temperatures, called refuges, which sheltered most part of the biodiversity at this time. It is known that such paleoclimatic changes affected the population dynamics of many species, especially in the Northern Hemisphere. However, it is still not clear how much these impacts influenced the species of the Neotropical region. The two species of this study, Drosophila maculifrons and Drosophila griseolineata, belong to the guaramunu group of Drosophila, and are considered sister-species that diverged about four million years ago. However, disregarding their close phylogenetic relationships, they present some distinct ecological patterns, the first species being more generalist, and the second more restricted to forest environments. Due to this ecological heterogeneity, these two species are potential indicators of the genetic consequences caused by the climatic fluctuations of the Quaternary, especially in face of a comparative perspective. The aims of this study were to evaluate the intraspecific diversity of different D. maculifrons and D. griseolineata populations, analyze the structure of individuals and populations in these two species of the guaramunu group and identify the ecological and evolutionary forces that modeled their distribution in Southern/Southeastern Brazil. In order to do so, 114 individuals were collected along the South, Southeast and Center-west regions of Brazil and Medellin, Colombia. Modeling analysis was performed, together with phylogenetic and phylogeographic analyses, with the last based in sequences of COI (Cytochrome Oxidase Subunit I) and COII (Cytochrome Oxidase Subunit II) genes. In general, the results that inferred the distribution of the most suitable habitat for each species indicate that the two species occur in sympatry at several points, although D. maculifrons is more widely distributed than D. griseolineata, at least in the brazilian territory. According to our phylogeographic analysis, D. maculifrons presents low levels of diversity and structure for mtDNA, which could be explained by a recent populational expansion event, dated for about 20 to 30 thousand years ago. On the other hand, D. griseolineata shows moderate levels of diversity and population structure, and its populations seem to have remained stables along time, showing a pattern of isolation by distance. So, it is interesting to evaluate the ecological and/or evolutionary factors which are responsible for all this difference, and this work represents a first step towards this understanding.
O período do Quaternário foi marcado por alterações consideráveis no clima e vegetação. No Hemisfério Sul, as glaciações foram mais amenas, entretanto, houve a redução da temperatura e o clima tornou-se mais seco. Dessa forma, ocorreram contrações na distribuição da Mata Atlântica e sua substituição por outros tipos, condizentes ao clima, como o Cerrado e a Caatinga. Assim, a vegetação de Mata Atlântica ficou restrita a locais úmidos e com temperaturas mais amenas, conhecidos como refúgios, os quais abrigaram grande parte da biodiversidade neste período. Sabe-se que essas alterações paleoclimáticas influenciaram a dinâmica populacional de muitas espécies, especialmente no Hemisfério Norte, porém ainda não está claro o quanto esses impactos influenciaram as espécies de distribuição Neotropical. As duas espécies em questão, Drosophila maculifrons e D. griseolineata, pertencem ao grupo guaramunu de Drosophila e são consideradas espécies irmãs, que divergiram aproximadamente há 4 milhões de anos. Porém, apesar do grau de parentesco, elas apresentam alguns padrões ecológicos distintos, sendo a primeira mais generalista e a segunda mais restrita a ambientes florestais. Devido a essa heterogeneidade ecológica, essas duas espécies são potenciais indicadoras das conseqüências genéticas ocasionadas pelas flutuações climáticas do Quaternário, principalmente em face de uma perspectiva comparativa. Os objetivos deste trabalho foram avaliar a diversidade intra-específica de diferentes populações de D. maculifrons e D. griseolineata, analisar a estruturação de indivíduos e populações nestas duas espécies do grupo guaramunu e inferir as forças ecológicas e evolutivas que modelaram sua distribuição ao longo do sul e sudeste brasileiros. Para isso, nossa amostragem conta com 114 indivíduos distribuídos ao longo das regiões Sul, Sudeste, Centro-Oeste do Brasil e Medellin na Colômbia. Foram realizadas análises de modelagem, bem como análises filogenéticas e filogeográficas, sendo que essas duas últimas basearam-se nas sequências dos genes COI (Citocromo Oxidase Subunidade I) e COII (Citocromo Oxidase Subunidade II). De uma forma geral, os resultados que inferiram a distribuição dos habitats mais adequados para cada espécie indicam que as duas espécies apresentam diversos pontos de simpatria, embora D. maculifrons seja mais amplamente distribuída em território brasileiro. De acordo com as análises filogeográficas, D. maculifrons apresenta baixos níveis de diversidade e estruturação em nível de DNA mitocondrial, o que pode ser explicado por um evento de expansão populacional recente, datado para aproximadamente 20 a 30 mil anos. Por outro lado, D. griseolineata apresenta níveis moderados de diversidade e estruturação populacional e suas populações parecem ter se mantido estáveis ao longo do tempo, apresentando um padrão de isolamento por distância. É, pois, interessante avaliar os fatores ecológicos e/ou evolutivos responsáveis por toda essa diferença, e esta dissertação representa um primeiro passo rumo a esse entendimento.

Abstract:
O complexo Drosophila buzzatii (grupo repleta) compreende 13 espécies, divididas em três clusters, de acordo com o bandeamento observado nos cromossomos politênicos: cluster D. stalkeri, incluindo D. richardsoni e D. stalkeri, restrito às ilhas do Caribe e Flórida; cluster D. martensis, incluindo D. martensis, D. uniseta, D. venezolana e D. starmeri, encontrado em áreas desérticas da Colômbia e Venezuela; e cluster D. buzzatii, incluindo D. buzzatii, D. koepferae, D. antonietae, D. serido, D. gouveai, D. borborema e D. seriema, habitando regiões sazonalmente secas ao longo da diagonal de vegetação aberta da América do Sul. O presente estudo teve como objetivo inferir as relações filogenéticas entre as espécies do complexo D. buzzatii, dando ênfase ao cluster D. buzzatii, por meio de análises multilocus de genes mitocondriais (COI e COII) e nucleares (EF-1F1, transformer e period). Nas hipóteses filogenéticas estabelecidas, as espécies do complexo D. buzzatii constituíram um grupo monofilético, composto por dois subgrupos monofiléticos, os clusters D. martensis e D. buzzatii, e um parafilético, o cluster D. stalkeri. As relações de parentesco entre as espécies do cluster D. buzzatii foram estabelecidas. Drosophila buzzatii ocupou a posição mais basal dentro do cluster D. buzzatii, estando proximamente relacionada à espécie D. koepferae. Drosophila antonietae ocupou uma posição intermediária em relação às espécies D. koepferae e D. serido, que representa o táxon irmão do ramo formado por D. gouveai, D. borborema e D. seriema, com D. gouveai ocupando uma posição mais basal em relação às espécies irmãs D. borborema e D. seriema. Foi detectada seleção purificadora como a principal força dirigindo a evolução dos genes nucleares transformer e period, para as espécies do complexo D. buzzatii. O gene mitocondrial COI, por sua vez, foi utilizado para estimar os tempos de divergência para as espécies do cluster D. buzzatii, revelando que o processo de diversificação do grupo iniciou-se no período Plioceno, provavelmente em decorrência de eventos de vicariância associados à elevação dos Andes, sendo também influenciado pelo avanço e retração da vegetação xerófita, nas flutuações climáticas do Pleistoceno.
Drosophila buzzatii complex (repleta group) consists of 13 species, divided into three clusters according to the banding seen in polytene chromosomes: D. stalkeri cluster, including D. richardsoni and D. stalkeri, restricted to the Caribbean Islands and Florida; D. martensis cluster, including D. martensis, D. uniseta, D. venezuelana and D. starmeri, found in desert areas of Colombia and Venezuela, and D. buzzatii cluster, including D. buzzatii, D. koepferae, D. antonietae, D.gouveai, D. borborema and D. seriema, that inhabit seasonally dry regions along the open vegetation diagonal in South America. This study aimed to infer the phylogenetic relationships among the D. buzzatii species complex, emphasizing the D. buzzatii cluster, by multilocus analysis of mitochondrial (COI and COII) and nuclear (EF-1F1, transformer and period) genes. In established phylogenetic hypotheises, the species of the D. buzzatii complex formed a monophyletic group, composed of two monophyletic subgroups, the D. martensis and D. buzzatii clusters, and a paraphyletic one, the D. stalkeri cluster. The relationships among the D. buzzatii species cluster were established. Drosophila buzzatii occupied the most basal position within the D. buzzatii cluster and is closely related to D. koepferae. D. antonietae occupied an intermediate position in relation to the D. koepferae and D. serido species. D. serido represents the sister taxon of the branch formed by the D. gouveai, D. borborema and D. seriema species, with D. gouveai occupying a basal position in relation to the sister species D. borborema and D. seriema. It was detected that purifying selection is the main force driving the evolution of transformer and period nuclear genes for the species of the D. buzzatii complex. The divergence time of the D. buzzatii species cluster was estimated by the COI gene analysis, revealing that the process of diversification of the group began in the Pliocene period, probably due to vicariant events associated with the uplift phase of the Andes, and it was also influenced by the advance and retraction of xerophytic vegetation in Pleistocene climatic fluctuations.

Abstract:
At least 2 billion people worldwide drink water from sources contaminated with feces, in other words, sources contaminated with E. coli. The traditional method for detecting E. coli, among other limitations, detects only culturable bacteria and takes about 24–48 hours to yield a result. Consequently, the aim of this work is to develop a rapid diagnostic procedure for E. coli by combining immunofluorescence and optoelectrokinetic patterning to specifically target and sensitively trap the whole organism. This is to ensure the populace have timely access to sustained “E. coli-free” water for both domestic and recreational activities. The procedure involves conjugation of streptavidin functionalized superparamagnetic fluorescent micro-beads with biotin-labelled anti-E. coli polyclonal antibody. The conjugate is introduced into a water sample containing E. coli among other contaminants, where it specifically and sensitively targets the bacteria in the sample solution which is quantified using an optoelectrokinetic patterning technique by introducing the targeted organism in a fabricated microfluidic chip and trapping it with an application of both laser beam and AC electric field simultaneously. Preliminary experiments have shown that increasing concentrations of E. coli in the microfluidic chamber varies directly with the electrical resistance of the entire system. This on-going research has the potential of sensitively isolating E. coli from a large pool of organic and inorganic contaminants in water in less than 4 hours.

Abstract:
Control of cell-to-surface adhesion has significant impacts on various biological and biomedical applications. In this study, the adhesion of Escherichia coli (E. coli) cells on nano/micro-textured surfaces produced by a unique surface texturing technique, aluminum-induced crystallization (AIC) of amorphous silicon (a-Si), was studied in order to control E. coli cell adhesion on glass substrates in an E. coli-based whole-cell chemical sensor. It was found that textured surfaces significantly enhanced cell-to-surface adhesion. Among the textured surfaces, nano/micro-textured surfaces showed advantage over micro-textured surfaces on the cell-to-surface adhesion. Study of the cell-to-surface adhesion mechanism suggests that the cell adhesion efficiency was controlled by the particle density of the textured surfaces.
