The species Pimelodus maculatus is one of the most abundant fish in many artificial reservoirs. Shows feeding plasticity and exploits all trophic levels in aquatic ecosystems. This study aimed to analyze and compare aspects of the diet of P. maculatus in two important tributaries (Taquari and Veados rivers) in the upper Paranapanema River system, and also investigate possible differences in the condition factor using its feeding habit as reference. Samplings were carried out every three months during 2011 and 2012 in two tributaries of Jurumirim's dam. After biometric analysis, fish were dissected to remove the stomachs that were fixed in formaldehyde 10% and conserved in alcohol 70%. The stomach content was analyzed under stereomicroscope and the food items were identified until the least possible taxonomic level. The diet was characterized based on the Alimentary Index (IAi). Feeding strategy and aspects of species autoecology were evaluated by the relation between abundance of prey-specific (Pi) and occurrence frequency (Fo) of the prey, and also was calculated the niche width of Levin (B). The condition factor was also established and values obtained in samples of both rivers were compared, correlating them with diet of the species

Stress is one of the major obstacles in frog culture and can be caused by factors such as inappropriate farming systems; inadequate management among other situations. The objective of the present study was to assess the hemogram, erythrogram and leukogram of bullfrogs (L. catesbeianus) when exposed to stress caused by different types of management: density and handling (manipulation), developed in the laboratory and repeated in the field for the appropriate comparisons in a experimental period of 30 days. The density experiment was conducted with four treatments: 70 animals m(-2) (D70); 100 animals m(-2) (D100), Control; 150 animals m(-2) (D150) and 200 animals m(-2) (D200), with 10, 14, 21 and 28 animals/box in the laboratory, respectively. Each treatment was performed with three simultaneous replicates. The handling experiment was conducted with three treatments: Treatment Without Handling (WH); Treatment with Partial Handling (PH) every 15 days and Treatment with Total Handling (TH) every 15 days. Each treatment was performed with four simultaneous replications. The methodology of the blood analysis followed international recommendations. In the present study we could observe that the animals of the field experiment did not reflect the same stress response observed in the laboratory in both experiment, which demonstrated the plasticity of these animals.

This study is resultant of the interview with the plastic artist Leda Catunda, when it emphasized for the feminine, the context and work’s creative process. For this, handle a ready of the technique and materials used in the work of artist into the reflection of the plastic language that prize the pictures and alternatives supports, assemblages that materially personifies itself in objects and topics from the popular culture.

O artista norte-americado Robert Mapplethorpe se notabilizou pela plasticidade de seus portraits em preto e branco, mas também pelo escândalo de suas composições, nas quais corpos nus, sobretudo masculinos podiam ser vistos em atos homoeróticos e sadomasoquistas. Considerada como uma arte erótica por uns e como pornografia por outros, o fotógrafo acendeu o antigo debate pornografia versus erotismo. Considerando que tanto uns quanto outros termos, só adquirem seu sentido estético, social e político se pensados contextual e historicamente. Tomamos as fotografias de flores deste autor, para levar a cabo este debate, dialogando, para tanto, com as contribuições de Michel Foucault pelas leituras da sexualidade enquanto dispositivo. Valemo-nos, ainda dos conceitos de ars erotica e scientia sexualis tratado pelo mesmo autor, para estruturar nossas hipóteses, nas quais as flores do fotógrafo são deslocadas do terreno relativamente seguro do erotismo para serem lidas como armas de um terrorismo textual (e visual), aquele que Barthes viu como capaz de 'interveir socialmente, não fraças à sua popularidade ou seu sucesso, mas graças à 'violência que permite que o texto exceda as leis que a uma sociedade, uma ideologia, ou uma filosofia tomam para construir sua própria 'inteligibilidade histórica'''.
