Bird communities in two fragments of semideciduous forest in rural São Paulo State.

A quali-quantitative survey was done in two fragments (75 and 100 ha) of semideciduous forest in rural São Paulo State. The aim was to characterize the bird community according to richness, abundance, and occurrence frequency in these areas. The qualitative survey showed 145 species in the Estação Ecológica de São Carlos-EESCar (Brotas)--and 173 in the Fazenda Santa Cecília-FSC (Patrocínio Paulista), while the quantitative survey showed the presence of 60 and 72 species in EESCar and FSC respectively. The isolation and the lower environmental quality of the EESCar fragment may be responsible for the lower number of species in this area compared to that of FSC. Abundance index value analysis (IPA) showed that both areas have a large number of species with low IPA and few species with intermediate or high IPA compared to the pattern observed in other surveys. At FSC, a larger number of occurrences of species in danger of extinction in São Paulo State was also observed. Apparently, the FSC fragment had better environmental quality for sheltering a larger number of species, including the endangered ones. The study of the community of birds is important in planning management and conservation of natural areas.

Foi realizado o levantamento quali-quantitativo de dois fragmentos (75 e 100 ha) de floresta estacional semidecídua do interior paulista. O objetivo foi caracterizar a comunidade de aves por intermédio da riqueza, abundância e freqüência de ocorrência nessas áreas. O levantamento qualitativo revelou 145 espécies para a Estação Ecológica de São Carlos - EESCar (Brotas) - e 173 para a Fazenda Santa Cecília - FSC (Patrocínio Paulista), enquanto o levantamento quantitativo mostrou a presença de 60 e 72 espécies para EESCar e FSC, respectivamente. O isolamento e a pior qualidade ambiental do fragmento da EESCar podem ser responsáveis pelo menor número de espécies dessa área em relação à FSC. Analisando o índice pontual de abundância (IPA), observa-se que ambas as áreas possuem grande número de espécies com baixo IPA e poucas espécies com IPA intermediário ou alto, conforme observações feitas em outros levantamentos. Na FSC foi observado também maior ocorrência de espécies ameaçadas de extinção no Estado de São Paulo. Aparentemente, o fragmento da FSC possui melhor qualidade ambiental para abrigar um maior número de espécies, inclusive as ameaçadas. O estudo da comunidade de aves é importante para a elaboração do plano de manejo e conservação das áreas naturais.

Distribuiçäo geográfica dos anestesiologistas da SBA no Estado do Rio Grande do Sul / Geographical distribution of the SBA (Brazilian Society of Anestesiologists) anesthesiologists in the state of Rio Grande do Sul

Os autores estudam a distribuiçäo geográfica dos anestesiologistas da SBA no Estado do Rio Grande do Sul em 1985, comparando os resultados com o estudo realizado em 1975. Os resultados mostraram uma significativa melhora no percentual da populaçäo assistida por esta especialidade, passando de 59% para 71,6%. Observou-se também uma tendência para a interiorizaçäo da especialidade, pois diminuiu de 53,4% para 44,2% o percentual de médicos anestesiologistas que trabalham na capital
