Mosquito community composition in dynamic landscapes from the Atlantic Forest biome (Diptera, Culicidae)

Mosquito community composition in dynamic landscapes from the Atlantic Forest biome (Diptera, Culicidae). Considering that some species of Culicidae are vectors of pathogens, both the knowledge of the diversity of the mosquito fauna and how some environment factors influence in it, are important subjects. In order to address the composition of Culicidae species in a forest reserve in southern Atlantic Forest, we compared biotic and abiotic environmental determinants and how they were associated with the occurrence of species between sunset and sunrise. The level of conservation of the area was also considered. The investigation was carried out at Reserva Natural do Morro da Mina, in Antonina, state of Paraná, Brazil. We performed sixteen mosquito collections employing Shannon traps at three-hour intervals, from July 2008 to June 2009. The characterization of the area was determined using ecological indices of diversity, evenness, dominance and similarity. We compared the frequency of specimens with abiotic variables, i.e., temperature, relative humidity and pluviosity. Seven thousand four hundred ten mosquito females were captured. They belong to 48 species of 12 genera. The most abundant genera were Anopheles, Culex, Coquillettidia, Aedes and Runchomyia. Among the species, the most abundant was Anopheles cruzii, the primary vector of Plasmodium spp. in the Atlantic Forest. Results of the analyses showed that the abiotic variables we tested did not influence the occurrence of species, although certain values suggested that there was an optimum range for the occurrence of culicid species. It was possible to detect the presence of species of Culicidae with different epidemiologic profiles and habitat preference.

Does Bt maize cultivation affect the non-target insect community in the agro ecosystem?

ABSTRACT The cultivation of genetically modified crops in Brazil has led to the need to assess the impacts of this technology on non-target species. Under field conditions, the potential effect on insect biodiversity was evaluated by comparing a homogeneous corn field with conventional and transgenic maize, expressing different Bt proteins in seven counties of Minas Gerais, Brazil. The richness pattern of non-target insect species, secondary pests and natural enemies were observed. The results do not support the hypothesis that Bt protein affects insect biodiversity. The richness and diversity data of insects studied were dependent on the location and other factors, such as the use of insecticides, which may be a major factor where they are used.

Annual Report of the Iowa Grape and Wine Development Commission for Fiscal Year, 2008

FY2008 was a productive year for the Iowa Grape and Wine Development Commission. Sixteen proposals were recommended for funding from FY2008 funds and carryover totaling just over $396,000 in outlays. Included in the approved proposals were staffing and equipment for the Midwest Grape and Wine Industry Institute’s wine diagnostics laboratory at Iowa State University, continued support for the viticulturist position at Des Moines Area Community College, funding for the second annual Mid-American Wine Competition, and assistance for marketing and promotion of Ice coats an Iowa vineyard after a February 2008 ice storm. Photo by Mike White and courtesy of Iowa State University. 16 two wine trail associations and seven festivals and events. Commission funding supported a salaried position within IDALS to manage the Iowa Grape and Wine Development Fund and to serve as the Director of the Iowa Grape and Wine Development Commission. The Commission approved funding for a Scholarship Program. The formally created Scholarship Committee met twice in FY2008 to finalize details for the Program and to approve scholarships to twenty-six applicants to aid with the expenses of accredited coursework. Based on data collected by IDALS, the Iowa Department of Economic Development, the Iowa Alcoholic Beverages Division, and Iowa State University the Iowa grape and wine industry appears to continue to be very viable and growth continues at a strong pace. Presently, Iowa ranks 14th in the nation for the number of wineries, and wine produced in the state for 2008 was estimated at a market value in excess of $14.0 million. A tabulation of the budget revealed that just over $1,080,000 in wine gallonage tax appropriations and legislative appropriations have been deposited into the Grape and Wine Development Fund from FY2003 through FY2008. Removing encumbered funds, expenditures have totaled just over $942,500 during that same time. “Financial” funding – used for fostering public awareness and participation of industry events - increased from 6% of expenditures in FY2007 to 9% in FY2008. Used for support of research, education, and outreach, a little over 80% of expenditures and encumbered funds were earmarked for “Technical” spending. Over time, funds invested in “Technical” programs will translate into an increasingly educated and institutionally-supported industry. Local, regional, and statewide events also appeared to be increasing in popularity. The Commission was encouraged to see increased support for these events. It is hoped, too, that the Scholarship Program will provide needed funding to help meet the educational goals of the industry’s workforce. As they continue to support Iowa’s grape and wine industry, the Commissioners look forward to working with individuals, commercial enterprises, state and federal agencies, and industry-sponsored institutions in FY2009 and in years to come.

Associations between psychiatric disorders and cardiovascular risk factors

Bien que de nombreuses études suggèrent des liens entre les troubles psychiatriques et les maladies cardiovasculaires (MCV), peu ont utilisé des investigations somatique, biologique et psychiatrique adéquates. Pour déterminer les potentiels mécanismes impliqués dans ces associations, plusieurs études ont investigué le lien entre les troubles psychiatriques et les facteurs de risque des maladies cardiovasculaires (FRCV) (surpoids, diabète, dyslipidémie, hypertension artérielle, inactivité, consommation de cigarettes). De plus, des biomarqueurs (régulateurs du métabolisme, marqueurs hépatiques et inflammatoires) pouvant être associés à la fois aux troubles psychiatriques et aux FRCV ont été étudiés mais avec des résultats contradictoires. Basée sur un large échantillon de la population générale de la Ville de Lausanne et des investigations somatique et psychiatrique adéquates, cette thèse comporte deux articles: le premier étudie l'association entre les troubles psychiatriques majeurs et les FRCV; le second établit les liens entre certains biomarqueurs et le développement du diabète de type 2. Appliquant une méthodologie rigoureuse sur un échantillon de 3716 sujets de la population lausannoise âgés de 35 à 66 ans, les résultats du premier article ont montré que 1) le sous-type atypique de la dépression était associé à une augmentation du risque de souffrir de plusieurs FRCV (surpoids, diabète et syndrome métabolique), contrairement à d'autres sous-types de dépression, 2) les problèmes d'alcool étaient associés à un risque accru de souffrir de diabète et de dyslipidémie, 3) presque tous les troubles psychiatriques étaient associés à une consommation régulière de cigarettes. Quant au deuxième article, parmi les différents biomarqueurs testés, seul un niveau bas d'adiponectine (une hormone produite par le tissu adipeux qui affecte la sensibilité à l'insuline) était associé à un risque accru de souffrir de diabète par la suite. Ces résultats soulignent la nécessité pour les spécialistes de distinguer les sous-types de dépression pour le risque cardiovasculaire et de donner une attention particulière au sous-type atypique. Un problème d'alcool comorbide pourrait accroître le risque cardiovasculaire. De plus, des efforts pour diminuer la cigarette chez les sujets souffrant de troubles psychiatriques seraient une mesure préventive importante contre le développement des MCV. Le rôle de l'adiponectine dans l'association entre les troubles psychiatriques et les FRCV restant incertain, une prochaine analyse devrait déterminer le lien entre ce biomarqueur et la dépression atypique. - Despite the fact that several studies have highlighted associations between psychiatric disorders and cardiovascular diseases (CVD), few have used adequate somatic, biological and psychiatric measures. To determine potential mechanisms implicated in these associations, several studies have assessed the relationship between psychiatric disorders and cardiovascular risk factors (CVRFs), such as overweight, diabetes, dyslipidemia, hypertension, physical inactivity and smoking. Moreover, biomarkers such as metabolic regulators, hepatic and inflammatory markers, which could be associated with both psychiatric disorders and CVRFs, have been studied yielding contradictory results. Based on a population-based sample from the city of Lausanne and using adequate somatic and psychiatric investigations, this dissertation encompasses two articles: the first studies the associations between major psychiatric disorders established for lifetime and CVRFs; the second studies the associations between certain biomarkers and the development of type 2 diabetes. Using standardized contemporary methodology in a sample composed of 3716 individuals aged from 35 to 66 years, the first article revealed associations between 1) the atypical depression subtype and an increased risk of several CVRFs (overweight, diabetes and the metabolic syndrome) in contrast to other depression subtypes; 2) alcohol disorders and an increased risk of diabetes and dyslipidemia; 3) almost all psychiatric disorders and a lifetime history of regular cigarette smoking. The second article showed, among the various biomarkers tested, that only lower levels of adiponectin (a hormone produced by adiposity which affects sensitivity to insulin) were associated with an increased risk of subsequent type 2 diabetes. Our results highlight the need for specialists to subtype depression when studying the cardiovascular risk and to pay particular attention to the atypical subtype. A comorbid alcohol misuse may further increase the cardiovascular risk. Moreover, efforts to diminish smoking in subjects suffering from psychiatric disorders could be an important tool for preventing subsequent CVD. The role of adiponectin in the association between psychiatric disorders and CVRFs should still be elucidated, and future analyses should focus in particular on the relationship between this biomarker and atypical depression.

Assessment of microbial community structure changes by amplified ribosomal DNA restriction analysis (ARDRA)

Amplified ribosomal DNA restriction analysis (ARDRA) is a simple method based on restriction endonuclease digestion of the amplified bacterial 16S rDNA. In this study we have evaluated the suitability of this method to detect differences in activated sludge bacterial communities fed on domestic or industrial wastewater, and subject to different operational conditions. The ability of ARDRA to detect these differences has been tested in modified Ludzack-Ettinger (MLE) configurations. Samples from three activated sludge wastewater treatment plants (WWTPs) with the MLE configuration were collected for both oxic and anoxic reactors, and ARDRA patterns using double enzyme digestions AluI+MspI were obtained. A matrix of Dice similarity coefficients was calculated and used to compare these restriction patterns. Differences in the community structure due to influent characteristics and temperature could be observed, but not between the oxic and anoxic reactors of each of the three MLE configurations. Other possible applications of ARDRA for detecting and monitoring changes in activated sludge systems are also discussed
