Tropicalia concerns the attempt of understanding of Brazil and a national identity characterized by the transience of time and space, rhizomatic action, perpetual laceration of cultural boundaries and at the same time act synchronously to instances such as policy and the social. A word created by artist Hélio Oiticica and registered by him on the National Register of Trademarks and Patents, was later used to a name the eponymous song by Caetano Veloso and also in this fertile cultural impulse at the turn of the sixties to the seventies on last century, who had the intention to make creating new spaces and simultaneously rethink the spatial cuts of Brazilian culture, encouraging them to be much more than a myth of a paradise within a lush new look of a tropical truth.

Information on endoparasites infecting Neotropical turtles is scarce. The present paper reports the occurrence of endoparasites in three adult individuals of Vanderhaege's Toad-Headed Turtle (Mesoclemmys vanderhaegei). The records include an undescribed nematode species in the genus Spiroxys, not previously reported for the family Chelidae, and the first South American record of a monogenetic trematode of the genus Neopolystoma.

The advertisement calls of Leptodactylus geminus, Leptodactylus gracilis, Leptodactylus plaumanni, and Leptodactylus fuscus are analyzed and compared with published reports. Based on calling data and examination of type material, Leptodactylus geminus is synonymized with L, plaumanni. To differentiate between the sibling species L. gracilis and L. plaumanni, fieldwork is needed, including recording of advertisement calls. Reliable identification of red specimens is not possible based on morphology and coloration alone.

Este artigo se propõe a analisar o período dos governos militares brasileiros (1964-1985) sob a ótica da cultura da legalidade. Pretendemos demonstrar como a tomada do poder político em 1964, longe de se caracterizar apenas pelo emprego da força e do arbítrio, foi pautada por um esforço jurídico, produzido com base numa determinada teoria do direito constitucional, com ênfase no pensamento de Carl Schmitt e Hans Kelsen.

Diplopods belonging to the subclass Helminthomorpha may present one or both leg pairs of the seventh diplosegment modified into structures that aid copulation, called gonopods. These structures are used as a taxonomic trait for the description of most species. In the genus Rhinocricus these structures are closely similar, so that it is difficult to distinguish species only on the basis of this trait. Two species, R. padbergi and R. varians, are found in the same habitat and present gonopods practically identical in shape; together they present a broad colour gradient, ranging from dark brown to light beige. Morphometric data for individuals of the experimental group were submitted to ANOVA and MANOVA, using Hotelling-Lawley Trace and generalized Mahalanobis distances (D 2) tests. The results demonstrated a relationship between size and colour, with darker individuals being larger. On the basis of this preliminary analysis, we may suggest that the two species are distinct since dark individuals are distant from medium- and light-coloured individuals according to the D 2 values. This seems to indicate a possible polymorphism of individuals belonging to R. padbergi which present close proximity in the values obtained. In all analyses, we observed that the main variables were diameter, length and telson size.

Mesoclemmys vanderhaegei is a Neotropical chelid lacking basic natural history studies. Based on a film made in December 2004, we describe the courtship behavior in this species. Field observations were conducted at Chapada dos Guimarães, Mato Grosso State, southwestern Brazil, in an oligotrophic stream amidst the savannah like Cerrado formation. We provide a schematic drawing of the behavioral sequences during courtship, as well as a flow diagram describing sequential responses of the female to the male behavioral patterns. Mesoclemmys vanderhaegei courtship behavior is similar to that described for other freshwater chelonians.
