Potenciais aves dispersoras de sementes das espécies vegetais zoocóricas da Mata da Bica, Botucatu - SP

The semidecidual forests, as tropical forests, presents zoochoric dispersal syndrome in the most of their plant species, with approximately one third of frugivorous species responsible for the seeds dispersal are birds. The bills width is a limiting factor, it must be equal or bigger than the seeds width, because the viable seeds dispersal depends on leaving the digestive system after been swallowed hole. Birds and plants inventorys were realized in a semidecidual Forest fragment, in Botucatu – SP, called Mata da Bica. After this, the birds consumers of fuits/seeds were selected (frugivorous, granivorous and onivorous) and also the zoochoric plants, both for building a possibilities matrix, to verify the potential seed dispersers according to the seeds and bills width. Going to the matrix end we can observe a decrease in the interaction possibillities, because the seeds width increases and the bills width decreases. It has been observed that 50,7% seeds could be dispersed by all listed birds, because the seeds were narrower than the narrowest bill. In the other way large seeded species, as Holocalix balansae and Hymemaea courbaril has shown only two possible dispersers: Trogon surrucura and Piaya cayana. There are no possible dispersers to Syagrus oleraceae in the matrix. The need for large birds or other animals that works as large seed disperses demand conservation efforts, since most of these animals need big and conserved areas for their life habits

Prevalence of Arterial Hypertension Among Seventh-Day Adventists of the Sao Paulo State Capital and Inner Area

Background: Inadequate life habits are known to favor hypertension, and Adventists recommend healthy life habits. Objective: To assess the prevalence of hypertension among Seventh-Day Adventists from the inner Sao Paulo state and Sao Paulo state capital. Methods: This study assessed 264 Adventists (mean age, 41.17 +/- 15.27 years; women, 59.8%) with a high religiosity level assessed by use of the Duke University Religion Index. Blood pressure was measured with a validated automatic device. The significance level adopted was p < 0.05. Results: The total prevalence of hypertension was 22.7% (27.4% in the inner state and 15% in the capital). The Adventists from the capital differed from those of inner state as follows (p < 0.05), respectively: higher education (62% vs 36.6%); employed by a third party (44%) vs self-employed (40.9%); family income (8.39 +/- 6.20 vs 4.59 +/- 4.75 minimum wages); individual income (4.54 +/- 5.34 vs 6.35 +/- 48; couple responsible for family income (35% vs 39.6%); vegetarianism (11% vs 3%); blood pressure (115.38 +/- 16.52/68.74 +/- 8.94 vs 123.66 +/- 19.62/74.88 +/- 11.85 mmHg); white ethnicity (65% vs 81.1%); married (53% vs 68.9%); lower tangible support in the social aspect (15.7 +/- 5.41 vs 16.9 +/- 4.32); and recalling the last time one's blood pressure was measured (65% vs 48.8%). On multivariate analysis, hypertension associated with the following: 1) vegetarianism (OR 0.051; 95% CI: 0.004-0.681); 2) educational level (OR 5.317; 95% CI: 1.674-16.893); 3) recalling the last time one's blood pressure was measured (OR 2.725; 95% CI: 1.275-5.821); 4) being retired (OR 8.846; 95% CI: 1.406-55.668); and 5) being responsible for family income (OR 0.422; 95% CI: 0.189-0.942). Conclusion: The prevalence of hypertension among Adventists was lower as compared with that reported in Brazilian studies, and it was lower in the Sao Paulo state capital as compared with that in the inner Sao Paulo state, possibly because of the better socioeconomic conditions and life habits of the former.

Stress urinary incontinence in climacteric women in a northeastern Brazilian municipality: a household survey

Low socioeconomic factors may influence the development of stress urinary incontinence (SUI). Thus far, there is little research available on SUI in developing countries. We aimed to determine whether the prevalence of SUI in a northeastern Brazilian municipality was higher or lower than in the general female population. Cross-sectional household cluster study of 1,180 climacteric women in the So Luis municipality (Maranho state, Brazil) was conducted using a standardized questionnaire that was previously tested in a pilot study and administered by interviewers to obtain socioeconomic and cultural information, climacteric aspects, and life habits related to SUI. From this population, 15.34% (n = 181) had SUI; this prevalence did not change with age. More than half (57.92%) of the patients replied that they had not consulted a physician for their SUI. The presence of SUI was not associated with any socioeconomic or gynecological variables after multivariate analysis. The prevalence of SUI in So Luis was similar to the rates observed in the general global female population. Socioeconomic and gynecological variables were not associated with SUI.

Cáncer y tratamiento oncológico: Representaciones sociales de la población general, el paciente oncológico y miembros del equipo de salud

Se realizaron tres estudios cualitativos que tuvieron como propósito conocer las representaciones que ha construido la población general, los pacientes oncológicos y los profesionales de la salud, sobre el cáncer, la quimioterapia y el trasplante de médula ósea y realizar un análisis sobre las semejanzas y diferencias entre ellos. Se realizó en la ciudad de Bogotá (Colombia) con 55 personas: 20 pacientes con cáncer en proceso de trasplante de médula ósea, 20 personas no diagnosticadas con cáncer y 15 personas que trabajan en la atención de pacientes con cáncer. Se realizó una entrevista en profundidad con todos los participantes y asociaciones libres, clásicas y por sustitución sobre las palabras “cáncer”, “quimioterapia” y “trasplante de médula”. Los datos conseguidos se analizaron a la luz de la Teoría de las Representaciones Sociales (TRS). El análisis de la información siguió la técnica de análisis cualitativo de contenido para encontrar significados simbólicos y construir, denominar y definir categorías. Para los tres grupos el cáncer es una enfermedad terrible, que puede llevar a la muerte. El personal de salud y la población general creen que la enfermedad genera terror, angustia y miedo. Los pacientes tienen conciencia de la gravedad y del temor consecuente por una enfermedad que lo cambia todo, produce sufrimiento, dolor, obliga a depender de alguien y puede conducir a la muerte. El personal de salud considera que los pacientes lo pueden vivir como un castigo y la población general que puede ser la consecuencia de estilos de vida poco saludables. Para todos, la quimioterapia es un tratamiento para la enfermedad, que por un lado presenta efectos colaterales difíciles y visibles y que producen sentimientos negativos de temor y de angustia y al mismo tiempo constituye una opción y posibilidad de curación. El Trasplante de Médula Ósea representa para todos una oportunidad.

Extracción de conocimientos de la diabetes tipo 1 utilizando la metodología de "Data Mining"

La diabetes mellitus es un trastorno en la metabolización de los carbohidratos, caracterizado por la nula o insuficiente segregación de insulina (hormona producida por el páncreas), como resultado del mal funcionamiento de la parte endocrina del páncreas, o de una creciente resistencia del organismo a esta hormona. Esto implica, que tras el proceso digestivo, los alimentos que ingerimos se transforman en otros compuestos químicos más pequeños mediante los tejidos exocrinos. La ausencia o poca efectividad de esta hormona polipéptida, no permite metabolizar los carbohidratos ingeridos provocando dos consecuencias: Aumento de la concentración de glucosa en sangre, ya que las células no pueden metabolizarla; consumo de ácidos grasos mediante el hígado, liberando cuerpos cetónicos para aportar la energía a las células. Esta situación expone al enfermo crónico, a una concentración de glucosa en sangre muy elevada, denominado hiperglucemia, la cual puede producir a medio o largo múltiples problemas médicos: oftalmológicos, renales, cardiovasculares, cerebrovasculares, neurológicos… La diabetes representa un gran problema de salud pública y es la enfermedad más común en los países desarrollados por varios factores como la obesidad, la vida sedentaria, que facilitan la aparición de esta enfermedad. Mediante el presente proyecto trabajaremos con los datos de experimentación clínica de pacientes con diabetes de tipo 1, enfermedad autoinmune en la que son destruidas las células beta del páncreas (productoras de insulina) resultando necesaria la administración de insulina exógena. Dicho esto, el paciente con diabetes tipo 1 deberá seguir un tratamiento con insulina administrada por la vía subcutánea, adaptado a sus necesidades metabólicas y a sus hábitos de vida. Para abordar esta situación de regulación del control metabólico del enfermo, mediante una terapia de insulina, no serviremos del proyecto “Páncreas Endocrino Artificial” (PEA), el cual consta de una bomba de infusión de insulina, un sensor continuo de glucosa, y un algoritmo de control en lazo cerrado. El objetivo principal del PEA es aportar al paciente precisión, eficacia y seguridad en cuanto a la normalización del control glucémico y reducción del riesgo de hipoglucemias. El PEA se instala mediante vía subcutánea, por lo que, el retardo introducido por la acción de la insulina, el retardo de la medida de glucosa, así como los errores introducidos por los sensores continuos de glucosa cuando, se descalibran dificultando el empleo de un algoritmo de control. Llegados a este punto debemos modelar la glucosa del paciente mediante sistemas predictivos. Un modelo, es todo aquel elemento que nos permita predecir el comportamiento de un sistema mediante la introducción de variables de entrada. De este modo lo que conseguimos, es una predicción de los estados futuros en los que se puede encontrar la glucosa del paciente, sirviéndonos de variables de entrada de insulina, ingesta y glucosa ya conocidas, por ser las sucedidas con anterioridad en el tiempo. Cuando empleamos el predictor de glucosa, utilizando parámetros obtenidos en tiempo real, el controlador es capaz de indicar el nivel futuro de la glucosa para la toma de decisones del controlador CL. Los predictores que se están empleando actualmente en el PEA no están funcionando correctamente por la cantidad de información y variables que debe de manejar. Data Mining, también referenciado como Descubrimiento del Conocimiento en Bases de Datos (Knowledge Discovery in Databases o KDD), ha sido definida como el proceso de extracción no trivial de información implícita, previamente desconocida y potencialmente útil. Todo ello, sirviéndonos las siguientes fases del proceso de extracción del conocimiento: selección de datos, pre-procesado, transformación, minería de datos, interpretación de los resultados, evaluación y obtención del conocimiento. Con todo este proceso buscamos generar un único modelo insulina glucosa que se ajuste de forma individual a cada paciente y sea capaz, al mismo tiempo, de predecir los estados futuros glucosa con cálculos en tiempo real, a través de unos parámetros introducidos. Este trabajo busca extraer la información contenida en una base de datos de pacientes diabéticos tipo 1 obtenidos a partir de la experimentación clínica. Para ello emplearemos técnicas de Data Mining. Para la consecución del objetivo implícito a este proyecto hemos procedido a implementar una interfaz gráfica que nos guía a través del proceso del KDD (con información gráfica y estadística) de cada punto del proceso. En lo que respecta a la parte de la minería de datos, nos hemos servido de la denominada herramienta de WEKA, en la que a través de Java controlamos todas sus funciones, para implementarlas por medio del programa creado. Otorgando finalmente, una mayor potencialidad al proyecto con la posibilidad de implementar el servicio de los dispositivos Android por la potencial capacidad de portar el código. Mediante estos dispositivos y lo expuesto en el proyecto se podrían implementar o incluso crear nuevas aplicaciones novedosas y muy útiles para este campo. Como conclusión del proyecto, y tras un exhaustivo análisis de los resultados obtenidos, podemos apreciar como logramos obtener el modelo insulina-glucosa de cada paciente. ABSTRACT. The diabetes mellitus is a metabolic disorder, characterized by the low or none insulin production (a hormone produced by the pancreas), as a result of the malfunctioning of the endocrine pancreas part or by an increasing resistance of the organism to this hormone. This implies that, after the digestive process, the food we consume is transformed into smaller chemical compounds, through the exocrine tissues. The absence or limited effectiveness of this polypeptide hormone, does not allow to metabolize the ingested carbohydrates provoking two consequences: Increase of the glucose concentration in blood, as the cells are unable to metabolize it; fatty acid intake through the liver, releasing ketone bodies to provide energy to the cells. This situation exposes the chronic patient to high blood glucose levels, named hyperglycemia, which may cause in the medium or long term multiple medical problems: ophthalmological, renal, cardiovascular, cerebrum-vascular, neurological … The diabetes represents a great public health problem and is the most common disease in the developed countries, by several factors such as the obesity or sedentary life, which facilitate the appearance of this disease. Through this project we will work with clinical experimentation data of patients with diabetes of type 1, autoimmune disease in which beta cells of the pancreas (producers of insulin) are destroyed resulting necessary the exogenous insulin administration. That said, the patient with diabetes type 1 will have to follow a treatment with insulin, administered by the subcutaneous route, adapted to his metabolic needs and to his life habits. To deal with this situation of metabolic control regulation of the patient, through an insulin therapy, we shall be using the “Endocrine Artificial Pancreas " (PEA), which consists of a bomb of insulin infusion, a constant glucose sensor, and a control algorithm in closed bow. The principal aim of the PEA is providing the patient precision, efficiency and safety regarding the normalization of the glycemic control and hypoglycemia risk reduction". The PEA establishes through subcutaneous route, consequently, the delay introduced by the insulin action, the delay of the glucose measure, as well as the mistakes introduced by the constant glucose sensors when, decalibrate, impede the employment of an algorithm of control. At this stage we must shape the patient glucose levels through predictive systems. A model is all that element or set of elements which will allow us to predict the behavior of a system by introducing input variables. Thus what we obtain, is a prediction of the future stages in which it is possible to find the patient glucose level, being served of input insulin, ingestion and glucose variables already known, for being the ones happened previously in the time. When we use the glucose predictor, using obtained real time parameters, the controller is capable of indicating the future level of the glucose for the decision capture CL controller. The predictors that are being used nowadays in the PEA are not working correctly for the amount of information and variables that it need to handle. Data Mining, also indexed as Knowledge Discovery in Databases or KDD, has been defined as the not trivial extraction process of implicit information, previously unknown and potentially useful. All this, using the following phases of the knowledge extraction process: selection of information, pre- processing, transformation, data mining, results interpretation, evaluation and knowledge acquisition. With all this process we seek to generate the unique insulin glucose model that adjusts individually and in a personalized way for each patient form and being capable, at the same time, of predicting the future conditions with real time calculations, across few input parameters. This project of end of grade seeks to extract the information contained in a database of type 1 diabetics patients, obtained from clinical experimentation. For it, we will use technologies of Data Mining. For the attainment of the aim implicit to this project we have proceeded to implement a graphical interface that will guide us across the process of the KDD (with graphical and statistical information) of every point of the process. Regarding the data mining part, we have been served by a tool called WEKA's tool called, in which across Java, we control all of its functions to implement them by means of the created program. Finally granting a higher potential to the project with the possibility of implementing the service for Android devices, porting the code. Through these devices and what has been exposed in the project they might help or even create new and very useful applications for this field. As a conclusion of the project, and after an exhaustive analysis of the obtained results, we can show how we achieve to obtain the insulin–glucose model for each patient.

Quantitative diatom-based reconstruction of paleoenvironmental conditions in Florida Bay and Biscayne Bay, U.S.A.

The spatial and temporal distribution of modern diatom assemblages in surface sediments, on the most dominant macrophytes, and in the water column at 96 locations in Florida Bay, Biscayne Bay and adjacent regions were examined in order to develop paleoenvironmental prediction models for this region. Analyses of these distributions revealed distinct temporal and spatial differences in assemblages among the locations. The differences among diatom assemblages living on subaquatic vegetation and sediments, and in the water column were significant. Because concentrations of salts, total phosphorus (WTP), total nitrogen (WTN) and total organic carbon (WTOC) are partly controlled by water management in this region, diatom-based models were produced to assess these variables. Discriminant function analyses showed that diatoms can also be successfully used to reconstruct changes in the abundance of diatom assemblages typical for different habitats and life habits. ^ To interpret paleoenvironmental changes, changes in salinity, WTN, WTP and WTOC were inferred from diatoms preserved in sediment cores collected along environmental gradients in Florida Bay (4 cores) and from nearshore and offshore locations in Biscayne Bay (3 cores). The reconstructions showed that water quality conditions in these estuaries have been fluctuating for thousands of years due to natural processes and sea-level changes, but almost synchronized shifts in diatom assemblages occurred in the mid-1960’s at all coring locations (except Ninemile Bank and Bob Allen Bank in Florida Bay). These alterations correspond to the major construction of numerous water management structures on the mainland. Additionally, all the coring sites (except Card Sound Bank, Biscayne Bay and Trout Cove, Florida Bay) showed decreasing salinity and fluctuations in nutrient levels in the last two decades that correspond to increased rainfall in the 1990’s and increased freshwater discharge to the bays, a result of increased freshwater deliveries to the Everglades by South Florida Water Management District in the 1980’s and 1990’s. Reconstructions of the abundance of diatom assemblages typical for different habitats and life habits revealed multiple sources of diatoms to the coring locations and that epiphytic assemblages in both bays increased in abundance since the early 1990’s. ^

Estratégias de enfrentamento de pessoas vivendo com AIDS frente à situação da doença

The Acquired Immune Deficiency Syndrome (AIDS), considered today one chronic nature of the disease due to the advent of antiretroviral therapy (TARV), brings to individuals living with this disease, difficulties related to social interaction and adaptation to new physical condition and the routines imposed by the treatment. This reality has a strong impact on the lives of these people in order of overcoming them use coping strategies, Coping. In this context, the aim of this study was to characterize the epidemiological, clinical and life habits of people living with AIDS and analyze the coping strategies used with the situation of the disease, according to sociodemographic, clinical and life habits. This is a cross-sectional study with a quantitative approach. The sample consisted of 331 people registered at the clinic of the Hospital Giselda Trigueiro (HGT), located in Natal / RN, who had scheduling for outpatient medical consultation from January to August 2014. The study was approved by the Ethics Committee the Federal University of Rio Grande do Norte with the Presentation of Certificate for Ethics Assessment (CAAE), paragraph 16578613.0.0000.5537. The data of social characterization showed predominance of men (52%), young people (42%) coming from the capital (58%), mulatto (53%), single (56%), heterosexual (79%), poor (68 %). With regard to clinical aspects it has been found that most held the first HIV testing for less than five years (60%) had signs and symptoms of AIDS before the examination (90%) were hospitalized (90%) started ART for less than five years (60%) believe they have good knowledge of the disease (75%) and believe that their health has improved (92%). For lifestyle, it became clear that most do not consume alcohol (71%), do not smoke (88%) and do not use illicit drugs (92%) and never used condoms before diagnosis (62%) and only 192 (58%) use the currently codon. With regard to the reference was higher coping focused modes of emotion, although the problem solving has been the second most common. The mean scores of women, workers, religious and never abandoned the treatment were higher for all factors. Having a partner, living with family members and support in the treatment had higher average scores for various factors, coinciding in the confrontation, withdrawal and social support. As for the leisure and physical exercise also dominated the modes focused on emotion as was seen in the correlation between the time of treatment, education and family income and IEEFL factors, although with low intensity. The profile of the study population confers with national characteristics, suggesting feminization, internalization, pauperization, heterosexual, increased CD4 cell count and viral load reduction during treatment and maintaining healthy lifestyle habits. Coping strategies used were more focused on emotion. In this context, it is understood that the identification of these strategies can facilitate care planning, encouraging such persons to adapt to stressors with the situation of the disease

Influence du vieillissement et de la scolarité sur la compréhension du discours : apport de l’imagerie optique

La compréhension du discours, et son évolution au cours du vieillissement, constitue un sujet d’une grande importance par sa complexité et sa place dans la préservation de la qualité de vie des aînés. Les objectifs de cette thèse étaient d’évaluer l’influence du vieillissement et du niveau de scolarité sur les capacités de compréhension du discours et sur l’activité cérébrale s’y rattachant. Pour ce faire, trois groupes (jeunes adultes ayant un niveau universitaire de scolarité, personnes âgées ayant un niveau universitaire de scolarité et personnes âgées ayant un niveau secondaire de scolarité) ont réalisé une tâche où ils devaient lire de courtes histoires, puis estimer la véracité d’une affirmation concernant cette histoire. Les capacités de compréhension correspondant aux traitements de trois niveaux du modèle de construction-intégration de Kintsch (la microstructure, la macrostructure et le modèle de situation) ont été évaluées. L’imagerie optique (NIRS) a permis d’estimer les variations d’oxyhémoglobine (HbO) et de déoxyhémoglobine (HbR) tout au long de la tâche. Les résultats ont démontré que les personnes âgées étaient aussi aptes que les plus jeunes pour rappeler la macrostructure (essentiel du texte), mais qu’ils avaient plus de difficulté à rappeler la microstructure (détails) et le modèle de situation (inférence et intégration) suite à la lecture de courts textes. Lors de la lecture, les participants plus âgés ont également montré une plus grande activité cérébrale dans le cortex préfrontal dorsolatéral gauche, ce qui pourrait être un mécanisme de compensation tel que décrit dans le modèle CRUNCH. Aucune différence significative n’a été observée lors de la comparaison des participants âgés ayant un niveau universitaire de scolarité et ceux ayant un niveau secondaire, tant au niveau des capacités de compréhension que de l’activité cérébrale s’y rattachant. Les deux groupes ont cependant des habitudes de vie stimulant la cognition, entre autres, de bonnes habitudes de lecture. Ainsi, ces habitudes semblent avoir une plus grande influence que l’éducation sur les performances en compréhension et sur l’activité cérébrale sous-jacente. Il se pourrait donc que l’éducation influence la cognition en promouvant des habitudes favorisant les activités cognitives, et que ce soit ces habitudes qui aient en bout ligne un réel impact sur le vieillissement cognitif.

Distribuição e abundância da malacofauna epibentônica no Parracho de Maracajaú, RN, Brasil

The mollusks present a great taxon variety and life habits in coral reefs being good environmental indicators. It is important to know the distribution pattern of the mollusks and the processes that influence it, so that disturbances in sea ecosystems could be monitored. The present study aims to accomplish the inventory and distribution of epibenthic mollusks in the Parracho of Maracajaú. 23 sites in different habitats of the Parracho were settled: 11 in the reef habitat, 3 in the sandy bottom and 9 in the seagrass bed. Qualitative and quantitative samplings have been done through snorkeling and scuba diving. Three band transects (10m²) were sampled in each site and the data were obtained to each m² of the transect, where the species were counted and the environmental variables (rugosity and recovery of the substratum) were valued. The data were submitted to multivariate analyses in order to find possible distribution patterns that could be associated to the substratum variables. The diversity indexes were calculated for each reef sites and compared with each other. A number of 46 species were registered. The reef habit at should to be the richnest area while the sandy bottom was poorest one. In the reef habitat, the mollusks were associated to rugosity and recovering of frondose algae and zoanthids, while for the seagrass bed, the animals exhibited a richness variation associated to the muddy and sandy sediment. There were found 3 species economically explored, what requires an appropriate management for the maintenance and conservation of the area resources in a sustainable way

Factors affecting gut metabolism and bioavailabilty of orange juice flavanones in humans

Several studies have supported a beneficial role of dietary flavonoids in reducing the risk/progression of chronic diseases (including hypertension, cardiovascular disease, certain cancers, type-2-diabetes, cognitive dysfunction, age-related bone disease). Their beneficial properties are likely to be affected by their structure, distribution in foods, food matrix, life habits (physical activity). Most dietary polyphenols reach the colon where they are metabolized to phenolic acids by gut bacteria. Lack of knowledge of the factors affecting flavonoid metabolism and bioavailability hinders understanding of their health effects. Therefore, this thesis aimed to investigate the effect of factors on bioavailability and metabolism of dietary polyphenols from orange juices (OJ) in in vitro and in vivo studies. In chapter 3, the variability of orange juice polyphenolic content was assessed using in vitro models of the human gastrointestinal tract. Chapter 4 investigated the reduced urinary phenolic acids after OJ and yoghurt (Y) in humans compared to OJ alone using in vitro models of the human gut. In chapter 5, raftiline and glucose were tested for effects on metabolism of hesperidin (flavanone not OJ). In chapter 6, an intervention study of 4 weeks moderate intensity exercise determined whether exercise affected bioavailability and metabolism of OJ flavanones in healthy sedentary females. The studies in this thesis showed that food sources, food matrix and physical exercise may determine the significant variations in bioavailability and metabolism of flavonoids, seen in a number of studies. These factors could result in differences in bioactivity and bioefficacy of polyphenols, and need to be taken into account in further studies of the effects of flavanones on disease risk.

Ecomorfologia de dez espécies de peixes marinhos mais abundantes de Galinhos/RN

Ecomorphology is a science based on the idea that morphological differences among species could be associated with distinct biological and environmental pressures suffered by them. These differences can be studied employing morphological and biometric indexes denominated Ecomorphological attributes , representing standards that express characteristics of the individual in relation to its environment, and can be interpreted as indicators of life habits or adaptations suffered due its occupation of different habitats. This work aims to contribute for the knowledge of the ecomorphology of the Brazilian marine ichthyofauna, specifically from Galinhos, located at Rio Grande do Norte state. 10 different species of fish were studied, belonging the families Gerreidae (Eucinostomus argenteus), Haemulidae (Orthopristis ruber,Pomadasyscorvinaeformis,Haemulonaurolineatum,Haemulonplumieri,Haemulonsteindachneri), Lutjanidae (Lutjanus synagris), Paralichthyidae (Syaciummicrurum), Bothidae (Bothus ocellatus) and Tetraodontidae (Sphoeroidestestudineus), which were obtained during five collections, in the period time of September/2004 to April/2005, utilizing three special nets. The ecomorphological study was performed at the laboratory. Eight to ten samples of each fish specie were measured. Fifteen morphological aspects were considered to calculate twelve ecomorphological attributes. Multivariate statistical analysis methods such as Principal Component Analysis (PCA) and Cluster Analysis were done to identify ecmorphological patterns to describe the data set obtained. As results, H.aurolineatumwas the most abundant specie found (23,03%) and S.testudineusthe less one with 0,23%. The 1st Principal component showed variation of 60,03% with influence of the ecomorphological attribute related to body morphology, while the 2nd PC with 23,25% variation had influence of the ecomorphological attribute related to oral morphology. The Cluster Analiysis promoted the identification of three distinct groups Perciformes, Pleuronectiformes and Tetraodontiformes. Based on the obtained data, considering morphological characters differences among the species studied, we suggest that all of them live at the medium (E.argenteus,O.rubber, P.corvinaeformis,H.aurolineatum,H.plumieri,H.steindachneri,L.synagris) and bottom (S.micrurum,B.ocellatus,S.testudineus) region of column water.
