The present work analyzed 150 UHT whole milk samples from three different brands, commercialized in city of Palotina (Paraná, Brazil), between October of 2004 and February of 2005. Mesophilic aerobic bacteria counting results were compared to the Agriculture Ministry of Brazil official standards (RTIQ) for UHT milk. 36 (24%) of the sample presented higher mesophilic bacteria counting according to the standards. Also, were proceeded physic-chemical analyses of those samples. 7.3% of the acidity results, 29% of crude fat and 50.7% of dry matter without fat were disagreeing to RTIQ. All samples accorded to the standards for cryoscopy and alcohol stability tests.

Land use dynamics is a consequence of socioeconomic system cycles. In this context, this work was developed aiming to evaluate land use alterations in Santa Bárbara watershed (Pelotas - Brazil), during 53 years (1953 - 2006), evidencing socioeconomic elements that contributed to this process. For land use dynamic analysis, maps of 1953, 1965, 1995 e 2006 were elaborated. Spatial changes that happened in Santa Bárbara watershed represent a regional process: pasture areas had decrease while culture lands had a gradual increase. This conjuncture is a consequence of the crisis in livestock destined to salted and dried meat production and of the food industry growth in Pelotas that impelled urban expansion, forest area reduction and artificial water reservoirs increase. © Scripta Nova, 2010.

The transit time of seeds ingested by frugivorous animals has important implications for the spatial distribution of seeds and their dispersal distance. Nevertheless, this parameter is rarely included in seed dispersal studies. In this paper, we provide information about the transit time of seeds of nine species of plants ingested by individuals of six species of captive birds (Turdus albicollis, T. amaurochalinus, T. leucomelas, T. rufiventris, Stephanophorus diadematus and Saltator similis). We found that (1) seeds are regurgitated quickly through the digestive tract of birds than defecated seeds, and (2) large seeds (e.g., > 5 mm in diameter for Turdus spp.) are regurgitated rather than defecated. These results corroborate other studies, but the relationship between seed size and transit time seems to be quite complex and variable, requiring more detailed studies on this important aspect of the ecology of seed dispersal and digestive physiology of frugivorous birds.
