A restauração ecológica em destaque: Um retrato dos últimos vinte e oito anos de publicações na área

The main aspects of restoration, in various ecosystems, are here discussed, by means of a bibliographic analysis of the last twenty-eight years. The main concepts, research themes and target ecosystems are also described.

Estudo da eficácia de espuma para a depopulação de aves para situações de emergência sanitaria

There are several difficulties in the control of quick spreading and highly contagious poultry diseases such as avian influenza and Newcastle disease, which require large numbers of poultry to be rapidly killed inside the poultry houses in order to minimize human exposure and disease spreading. We have built and tested an equipment that uses a waterbased foam from high expansion fire detergent that induces poultry anoxia measured by sensorial signs, time to death, lethality and macro and microscopically lesions. Two hundred 78-weeks old hens were divided into ten groups and exposed to different times of death according to exposure to water-foam varying from 5min30s to 8min15s. All poultry died after six minutes of water-foam cover. Foam bubbles were observed in oral cavity and trachea of all poultry at each time of exposure to foam, revealing physical asphyxia. Macroscopically, congestion in oral cavity and in trachea mucosa was observed. Histopathology revealed diffuse and moderate hemorrhage in lungs and no lesion in trachea. The efficacy of water-foam procedure for poultry depopulation was demonstrated validating its recommendation in case of emergency.

Eficácia do tetra-test como ferramenta de gestão da qualidade do leite cru refrigerado

The effectiveness of a new management tool for screening refrigerated raw milk quality in a dairy industry is provided. Three hundred and seventy-four samples of raw milk from individual producers and 125 samples from bulk milk carriers from the same producers were analyzed. Producers' samples underwent a fast tube reduction test, or Tetra-Test, to estimate total bacteriological charge and their predominant microbiota. Bulk milk samples underwent standard plate count (SPC) as reference method. Tetra-test was effective in screening and assessing the microbiological quality of refrigerated raw milk, since 82.4% of samples with more than 106UFC/mL were readily detected (5 minutes to 2h). The test may be employed as a management tool either in screening or in interventions on the detected problem. In fact, its results provided complementary information on the characteristics of dominant microbiota. Most samples failed in compliance to IN 51 requirements. Further, 211 samples (56.4%) showed high microbial charge and, consequently, poor quality raw milk. Psychrotrophic groups were not yet the main degrading factors of cooled raw milk, albeit present in 76.8% of samples.

Occurrence record of Sus scrofa Linnaeus, 1758 (Mammalia: Artiodactyla) at Estação Ecológica de Itirapina, São Paulo state, Brazil

Invasive species are the second cause of biodiversity decline in the world. Among the many invasive species, the Sus scrofa (wild boar) is amongst those that cause more impacts. Our aim was to report the presence of the wild boar in the last remaining open area of Cerrado in the São Paulo state, Brazil. In September 2007 an individual was seen and tracks were also observed during the same period at the Estação Ecológica de Itirapina. © 2013 Check List and Authors.

Florística e fitossociologia em áreas de campo sujo e cerrado sensu stricto na Estação Ecológica de Pirapitinga-MG

The objectives of this study were to characterize the floristic and to calculate the phytosociological parameters of species present in the areas of 'campo sujo' and 'cerrado' sensu stricto in the Ecological Station of Pirapitinga, Minas Gerais state (ESEC). For the floristic and phytosociologic survey, a total of 190 plots of 100 m2 each were allocated, where all the individuals with circumference at soil level (CSL) ≥ 16 cm in areas of 'campo sujo' and 'cerrado' sensu stricto were sampled. The parameters of frequency, density, dominance, and importance values and Shannon and Pielou indexes were calculated. The floristic similarity between areas was determinated by Sorensen index. In the study areas, a total of 3,224 individuals distributed in 81 species, 70 genera and 40 families were sampled. The richest families were Vochysiaceae and Fabaceae. The cerrado sensu stricto was the vegetal formation with the highest richness of species (81) and highest density (2.257 ind ha-1). Both areas have studied with high diversity and ecological dominance and have low diameter distribution in the form of inverted-J, indicating the predominance of young individuals.
