Agressividade relacionada ao contexto alimentar em escorpião-amarelo Tityus Serrulatus (Lutz & Mello, 1922)(Scorpiones, Buthidae)

Scorpions are among the oldest living groups of animals, and are present in almost every continent. Although many studies are made about the toxins present in their venom, little is known about their behavior. The aim of this paper is to investigate the expression of agressiveness in the brazilian yellow scorpion Tityus serrulatus, specifically the relation between agressiveness, motor activity and feeding condition. The study was divided in two parts. First, we used 16 adult individuals, placed in two terrarium, to establish an ethogram. Each group was observed for 36h, and the behaviors displayed were described and categorized as agonistic or non-agonistic. In the second part of the experiment, we used 32 adult animals in three different nutritional states: Feeding (still ingesting food), Sated (1 to 4 days since last meal) and Deprived (14 to 25 days since last meal). The individuals were paired, each pair placed in a terrarium and observed for 30min. Behaviors displayed were timed in seconds. Our results show that only Feeding individuals displayed agonism towards others, and no relation was observed between motor activity and feeding conditions

Fator de condição e biologia alimentar de Pimelodus maculatus em três pontos do Rio Piracicaba (SP)

A number of 170 individuals of the species Pimelodus maculatus, a Neotropical fish known as mandi was collected in three distinct locations of the Piracicaba river (Piracicaba, Santa Maria da Serra and Americana – SP0 from April 2009 to February 2010. A common species of catfish whose individuals exist in many neotropical basins was observed to get more information about a possible influence of the water conditions in distant parts of a same river to its condition and also to verify whether the stomach contents of fish collected in these distinct places may distinguish as a possible consequence of food availability. The species were studied by collecting biological data such as standard length (SL) in cm, their total weights (TW ) in grams and sexes to see the composition of fish present in the samples. Length-weight relationships are important means to investigate facts related to the condition of the species in these systems. The analysis was made by using covariance to observe if individuals of similar lengths collected in distinct places may be compared to this purpose. Usual methods to investigate relationships of stomach food contents were applied. By analyzing the condition factor, one may conclude that the mandis collected in the region of Santa Maria da Serra presented similar characteristics to those obtained in Piracicaba, but they differ in this aspect for individuals collected in Americana. This fact is not conclusive about the reasons of this situation, but it may be a first step to other studies in order to get more information about. The degree of stomach repletion may be a first approach to this possible explanation, as individuals of Piracicaba presented usually full stomachs and differed in this way to individuals collected in the two other places

Estudo da dispersão pós-alimentar em larvas de moscas-varejeiras via autômatos celulares

In this paper, a computational analysis, using a cellular automata model, has been developed to analyze post-feeding dispersal behavior of blow y larvae. This model aimed to: simulate the exponential decline of pupal number in relation to the feed source and spatial oscillation due to larval interaction during dispersal; study whether the prior pupal presence in uences distribution patterns of larval frequency; and compare obtained unidirectional dispersal patterns to the cross-dimensional ones. The cellular automata (CA) model was able to successfully reproduce the essential features of the larval dispersal process and, thus, show the importance of local interaction in the studied dispersal process dynamics. Oscillations could be explained by the interaction among dispersing larvae and intrinsic pupation time. The box size and the initial larval density were important factors for the experiment because they in uenced the results. Results showed that the unidirectional dispersal could be used to simulate the larval dispersion that occurs in the natural environment, because both models had a similar result. These results are important to understand how di erent factors can in uence the dynamics of blow y larval dispersal, bringing important results for behavioral ecology and forensic entomology

Análise cinemática e dinâmica para conversão de um VW saveiro em veículo elétrico

This work aims to kinematic and dynamic analysis of a VW Saveiro in order to estimate the power requested to the engine with the imposed movement conditions. Thus, the study will be the basis to the specification of the electric engine, on the conversion of the internal combustion vehicle into electric one. First of all, a literature review was done in order to understand the state of the art for this issue and come up with the technical features of the vehicle in question. The next step is the identification and calculation of all forces acting on the prototype in motion, from 0 to 120 km/h, in intervals of 10 km/h, under the defined conditions of path and time. Then, were determined the values of the torque and rotation of the components from the transmission system, as well as the engine power, for each speed range. The results show the most influential forces on the resistence of the movement in each speed range, and the behavior of the torque curve is verified. Finally, it was also analyzed the implementation of pinwheels on the frontal area of the vehicle, in order to convert wind energy into electrical energy to supply the lighting subsystem of the vehicle and the proposal was validated. Limiting the maximum speed of the vehicle to 90 km/h, it was finally concluded that the power of the electric engine should be 40 HP

Influência da fonte alimentar na infecção de triatomíneos por Trypanosoma cruzi

Embora a doença de Chagas seja amplamente estudada, ainda não se conhece todos os interferentes que modulam a relação parasitária Trypanosoma cruzi- vetor- hospedeiro vertebrado. Sabe-se que as aves são refratárias ao T. cruzi, ou seja, o parasito não consegue estabelecer parasitismo nas mesmas, enquanto que nos camundongos a infecção ocorre. Essa refratariedade representa um exemplo de resistência natural do hospedeiro a uma infecção parasitária. Originalmente, acreditava-se que isso ocorria devido à presença de um anticorpo natural contra o T. cruzi no sangue das aves, porém estudos atuais atribuem tal atividade ao sistema complemento presente no sangue das mesmas. Pretendeu-se avaliar neste projeto se a referida característica peculiar do sangue das aves interfere no processo e no nível de infecção dos triatomíneos, em especial de Rhodnius neglectus, espécie de comprovada importância epidemiológica. Para tanto, utilizou-se a cepa Y de T. cruzi e ninfas de 4º estádio de R. neglectus. Avaliou-se também a capacidade lítica do soro de galinha em formas epimastigotas e tripomastigotas em meio de cultura LIT, utilizando a cepa Y. Referente à influência de diferentes fontes alimentares na infecção de R. neglectus por T. cruzi, observou-se um decréscimo no número de exemplares infectados após alimentação em patos , apresentando Índice de Infecção médio de 19,74%. Por outro lado, exemplares infectados após alimentação em camundongos não apresentaram diferença significante na parasitemia total. Os testes in vitro demonstraram que a adição de soro de galinha em meio de cultura LIT, com formas epimastigotas e tripomastigotas, foi capaz de diminuir notoriamente a contagem de parasitos móveis até a contagem zero, uma hora após a adição. O conjunto desses resultados sugere que a refratariedade das aves ao T. cruzi influencia a infecção de R. neglectus pelo flagelado e foi demonstrada, in vitro, pela ...

Significados da reforma agrária em bairros periféricos de Presidente Prudente (SP): uma tentativa de diálogo entre a luta pela Terra e a soberania alimentar

La lucha por la tierra en el Brasil se confunde con la própria historia del país, erigida sobre una cuestión agraria turbulenta en la cual ha predominado la hegemonía de los grandes proprietarios de tierra, tanto en la forma de latifundistas, cuanto, más recientemente, de los empresarios del agribusiness, caracterizando una versión más moderna de la dominación de la lógica del capital en detrimento de las demás formas de organización de la vida. A partir de la segunda mitad del siglo XX, ocurre un aguzamiento de los conflictos por la tierra con la emergencia de los principales movimientos sociales en Brasil, como el MST. Esos movimientos surgen en un contexto de transformación de la formación socioespacial brasileña, marcada por la creciente urbanización del país, lo que repercute em las sus formas de organización, pasando a comparecer una preocupación con la población urbana en las discusiones y acciones en pro de la Reforma Agraria. Yuxtaponiendo-se a eso proceso, también ha emergido fortemiente en las últimas décadas la problemática de la hambre en el mundo, tanto a través de los dados alarmantes de los organismos supranacionales (FAO), como del debate impulsado por los movimientos sociales acerca de la Soberanía Alimentaria (Via Campesina). Todos esos elementos merecen atención em esto trabajo, que busca aprehender cómo se efectiva la participación de barrios de la periferia pobre de la ciudad de Presidente Prudente/SP en el proceso de lucha por la tierra en el Pontal del Paranapanema, haciendo eso por lo medio de una lectura geográfica de esa realidad que prime por la superación analítica de la disociación entre ciudad y campo, como se fueran espacios inertes entre sí. Además, es nuestro objetivo destacar las motivaciones que llevan los sujetos protagonistas de eso proceso a dejaren la ciudad y adhieriren a la lucha por la tierra, permitiendo identificar elementos que extrapolan la esfera económico-material
