Abstract: The introduction of new breeds, aiming at increasing productivity, caused the change in the health profile of herds. Among the diseases introduced in Brazil lentiviroses of small ruminants (LVPR) stand out, represented by caprine arthritis encephalitis (CAE) and the maedi-visna (MV). In order to obtain data concerning the presence of maedi visna (MV) in sheep herds in the microregion of Juazeiro, Bahia, 919 serum samples were evaluated by agar gel immunodiffusion (AGID). The samples were collected in eight cities that make up this microregion (Juazeiro, Sento Se, Sobradinho, Pilao Arcado, Campo Alegre Lourdes, Remanso, Casa Nova and Curaca) considering how representative each municipality is within the totalilty of animals. It was observed that 0.34% of the sampled sheep showed positive reaction in the AGID. It was concluded that the MV occurs with low prevalence in the studied microregion, probably due to the predominance of locally adapted breeds. KEYWORDS: AGID; antibodies; Lentivirus; occurrence.

Abstract: This paper is an inventory of moss species occuring in diferent types of vegetation in the Zona Bragantina, Salgado microregion and Viseu municipalities, all located in the northeast of Para. The results found 60 species and one variety in 632 moss samples, distributed in 30 genera and 16 families. Sematophyllaceae, Calymperaceae e Leucobryaceae were prominent in diversity of species and number of occurrencies. Sematophyllum subsimplex (Hedw.) Mitt. and Calymperes lonchophyllum Schwaegr. are the most abundant species. The results found at Salgado Microregion were compared to the results found at Zona Bragantina and Viseu municipalities. There is a higher diversity in primary vegetation, indicating that the replacement by the secondary vegetation results in the impoverishment of moss species diversity.

Abstract: This paper aims to test if there is a spatial interaction on municipal expenditures (health, education and investments) in electoral years. The test is performed using data from 1997 to 2008 as Lockwood & Migali (2009). Our results suggest that there is positive spatial interaction between municipalities belonging to the same microregion in health and education expenditures. In electoral years the average increase is potentiated in investments and education expenditures. These results point out that increasing expenditures in electoral years may occur as a fiscal response by the city to the fiscal actions made by the microregion neighborhood.
