Memórias de um palhaço: O rito de passagem de Roger Avanzi para o palhaço Picolino II

This dissertaion reflects about life's trajectory of a specific clown: Roger Avanzi, who gives animus to the clown Picolino II. The main objective is to promove reflections about the insertion of the clowns in the universe of the circus, to make us comprehend the process of formation of a clown formed in a traditional circus family. In this research, we begin of the conjecture that, through the individual memory we can think about rebuild the process of a professional's integral formation.Then, we trace the itinerary of Roger Avanzi, the clown Picolino II, think that it has possibilities, in this case, to discuss about what is a clown's formation when it come from a traditional circus family. To walk on this universe, a huge numer of authors that deeply studyed about the circus ans the clowns, like: Avanzi; Tamaoki (2004), Bolognesi (2003), Castro (2005), Pantano (2007), Ruiz (1987), Silva (1997) e Torres (1998). We bring then, a theoric base that certainly, fortifies and corroborates our thoughts and reflections about the universe of circus and the trajectory of clown's formation, with special atention to Roger Avanzi, fundamentals i studies about it and with memories like Halbwachs's (2004) and Bosi's (1994). The reflections enabled to conclude that a clown doesn't born done; it becomes in the cultural trajectory, in which all the human are inserted

Nest architecture and population dynamics of the Ponerinae ant, Ectatomma opaciventre Roger (Hymenoptera : Formicidae)

Eleven nests of Ectatomma opaciventre were collected from January to December, 1994, in Rio Claro, SP, southeastern Brazil. This species excavates their nests up to 68 cm deep, containing 3, 4 or 5 chambers. The hole of entrance has a chimney-like rigid structure, with up to 2/5 cm high. The most numerous colonies were found in January and February, with 47 and 62 adult ants, respectively. The quantity of individuals decreased from March, being observed colonies with only 9 adult ants in June and July. The colony population increased again since September. Reproductive forms (winged ants) were observed between October and February. We did not observed immature stages in July, but they were numerous between September and March. There was a significant correlation between the number of colony individuals and temperature, but not between the number of colony individuals and relative humidity and rainfall. E. opaciventre is a species of hunter ants which have not an efficient recruitment system for food collecting, consequently their colonies are small due to the scarcity of food resources during the colder and dry months.

Book Review of Birds of the Great Plains by Bob Jennings, Ted T. Cable, and Roger Burrows

Though intended as a field guide to the birds of the Great Plains, this book seems to serve best as a general introduction to Great Plains birds and will mostly benefit those casually interested in birds. The definition of Great Plains the book uses is rather broad, and some species are included that, in my opinion, aren't really birds of the Great Plains. For example, several warblers are included as breeding species although they nest within the book's definition of the region only in the conifer or mixed forest of north-central to northwestern Minnesota, which isn't really a part of the Great Plains proper.

Assembly of Myrmelachista Roger (Formicidae: Formicinae) in twigs fallen on the leaf litter of Brazilian Atlantic Forest

The nests of Myrmelachista are found in tree trunk cavities and branches. The biology of these arboreal ants is still relatively unknown. We investigated the nesting behaviour of this genus in fallen dry twigs in the Atlantic rainforest of southeastern Brazil. Physical characteristics of the nests, colony demographics, presence of breeders and ant worker sizes were recorded. Samples were collected weekly for 12 months, along open, sunny and undisturbed trails within forest remnants. In all, 202 nests were collected and six species were recorded. Myrmelachista ruszkii had the highest population of immatures and the greatest number of nests found. Myrmelachista nodigera had the smallest workers, was the least populous and the colony was housed in the finest branches. These results expand the current knowledge about the diversity and biology of Myrmelachista in the Brazilian Atlantic forest, and describe polydomic nests and competitive behaviour of M. ruszkii.
