Non invasive methods for genetic analysis applied to ecological and behavioral studies in Latino-America

Documenting the presence and abundance of the neotropical mammals is the first step for understanding their population ecology, behavior and genetic dynamics in designing conservation plans. The combination of field research with molecular genetics techniques are new tools that provide valuable biological information avoiding the disturbance in the ecosystems, trying to minimize the human impact in the process to gather biological information. The objective of this paper is to review the available non invasive sampling techniques that have been used in Neotropical mammal studies to apply to determine the presence and abundance, population structure, sex ratio, taxonomic diagnostic using mitochondrial markers, and assessing genetic variability using nuclear markers. There are a wide range of non invasive sampling techniques used to determine the species identification that inhabit an area such as searching for tracks, feces, and carcasses. Other useful equipment is the camera traps that can generate an image bank that can be valuable to assess species presence and abundance by morphology. With recent advances in molecular biology, it is now possible to use the trace amounts of DNA in feces and amplify it to analyze the species diversity in an area, and the genetic variability at intraspecific level. This is particularly helpful in cases of sympatric and cryptic species in which morphology failed to diagnose the taxonomic status of several species of brocket deer of the genus Mazama.

A literatura latino-americana e as alegorias nacionais de concierto Barroco

The problematical identity of Latin America is reflected on the recurrence of the theme in the literature created in this part of the continent. The images of Caliban and anthropophagy and the attribution of a Baroque meaning to the Latin American experience characterize an expressive part of such literature. By means of the character Amo, Carpentier's Concierto Barroco exemplifies the difficulties of the Creole elite in finding a nobleorigin for themselves in their ancestors' Europe, and in identifying themselves with it. The slave musician Filomeno and Amo naturalizes narrative, whereas Filomeno provocativelytransits between the hierarchies, turning the Baroque meaning of identity into an allegory. Jazz is a Creole, anthropophagic and Baroque product whose erased origin was replaced by the fabled narrative in the Spirituals that renewed modern music. It is important to emphasize that Carpentier created, by means of Filomeno, the unity of the American experience whose frontier is Mexico.
