Breastfeeding knowledge and practice of health professionals in public health care services

Objetivou-se avaliar conhecimentos e práticas sobre aleitamento materno de profissionais que atendem lactentes em unidades de atenção básica, ou maternidades públicas, de município do interior paulista, Brasil. É estudo epidemiológico, sendo a população composta por 89 enfermeiros e médicos. Suas respostas a um questionário estruturado foram analisadas no total e segundo o local de trabalho, aplicando-se o teste de diferença de proporções (qui-quadrado), considerando-se p<0,05 como nível crítico. Como parâmetros de acertos foram consideradas as recomendações do Ministério da Saúde. As diferenças significativas para conhecimentos e práticas, segundo o local de trabalho, foram restritas a alguns aspectos, com resultados discretamente melhores dos escores médios de acertos dos profissionais das unidades de atenção básica. Independente do local de trabalho, verificou-se desempenho regular e ruim em diferentes aspectos estudados, indicando que possíveis intervenções para a capacitação nessa temática deverão incluir profissionais de todos os níveis de atenção à saúde.

Bird species distribution and conservation in Serra do Cipo, Minas Gerais, Brazil

We studied the distribution of birds along an altitudinal gradient ranging from 800 m to 1,400 m on two slopes of the Serra do Cip6, Minas Gerais, southeastern Brazil. Ornithological surveys were conducted over transects covering open (cerrado, campo rupestre) and forested (gallery and Atlantic forest) habitats from 1994 to 2000. We found 273 bird species belonging to 51 families. Twenty-two species were restricted to higher elevations and 84 Species were detected on only one slope, depending on the vegetation type they inhabited. We recorded 104 species occurring on both slopes, while 61 species were considered altitudinal generalists. Six species, including Hyacinth Visorbearer Augastes scutatus and Cip6 Canastero Asthenes luizae were restricted to the highest parts of Serra do Cip6, a fragile habitat important to endemic birds of the Espinhaco Range. In the past 10 years, the Serra do Cip6 region has suffered human impacts on a large scale, and conservation action must be developed to protect the fauna and flora confined to the area.

Ecology and conservation of the jacutinga Pipile jacutinga in the Atlantic Forest of Brazil

The jacutinga Pipile jacutinga was formerly one of the most abundant game bird cracids in the Atlantic forest of Brazil. Nowadays this species is vulnerable to extinction due to hunting and habitat loss. The ecology of the jacutinga was studied at Parque Estadual Intervales, Sao Paulo, Brazil from October 1993 to December 1995 and in adjacent areas. Jacutingas were observed to feed mainly on the sugar-rich fruit of 41 species. We recorded a low index of abundance for the jacutinga (0.018) or c.1.7 birds/km2 at Intervales, one of the best protected areas within their range. Surveys carried out in the Atlantic forest of Sao Paulo found jacutinga populations in 14 localities. Probably < 1500 birds survive in the best protected areas. The species' stronghold in southeastern Brazil is in the mountains of Serra de Paranapiacaba, an area protected by several parks suffering from hunting and palm heart harvesting and threatened by a hydroelectric project.

On a nest of the Planalto Woodcreeper, Dendrocolaptes platyrostris, with taxonomic and conservation notes

A pair of Planalto Woodcreepers (Dendrocolaptes platyrostris) fed young in a nest cavity 6 m up in a wooded botanic garden of an old eucalyptus grove near São Paulo, Brazil, during October 1982. The pair often visited together at first, one (likely male) raising its head feathers as noted in other species of the genus. Feedings were less frequent at midday. Songs of the southeastern moist forest D. p. platyrostris were strikingly different from inland dry forest D. p. intermedius, despite intermediate specimens where the two rather distinctly colored forms come together. There are several poorly studied forms in interior dry forests, which need much more conservation effort.

Alien fishes in lakes of the Doce river basin (Brazil): Range, new occurrences and conservation of native communities

The present study shows the distribution of alien fish species in tropical lakes in the middle Doce river basin, southeastern Brazil, obtained from a rapid assessment program. The causes for their introductions were sport-fishing improvement in some specific lakes and aquaculture in the studied basin. Presently, these species have a wide distribution occurring in 41 of the 54 lakes studied, representing an actual threat to regional native fish community. The natural connection among lakes and streams during the rainy season and the dispersal mediated by local people are the main invasion agents for alien fishes. The success of these invaders is probably due to absence of pre-existing effective competitors or top-predators in the invaded communities. We consider that the eradication of alien fishes by means of the available management tools may be very difficult due to the large number of lakes invaded and to the wide spectrum of lake conditions and resources exploited by these alien species. We recommend the use of environmental education as a tool to stop the human-mediated dispersion of aliens and to improve conservation of native fish community in lakes where these alien species are not present yet. © 2004 Instituto de Ciências Biológicas - UFMG.

Molecular studies of Callithrix pygmaea (Primates, Platyrrhini) based on transferrin intronic and ND1 regions: implications for taxonomy and conservation

As classificações tradicionais envolvendo os macacos da infraordem Platyrrhini, principalmente baseadas em características morfológicas, têm sido contestadas por dados moleculares recentes. A subfamília Callitrichinae (Platyrrhine, Primates) engloba um diverso grupo de espécies, muitas das quais consideradas em perigo de extinção. A presente análise de duas regiões do DNA, um gene mitocondrial (ND1) e um gene nuclear (regiões intrônicas da transferrina), sugerem que Callithrix pygmaea apresenta variabilidade suficiente para justificar a existência de subespécies ou até mesmo de espécies distintas. As árvores filogenéticas baseadas na região do ND1 indicam que esta espécie está relacionada mais proximamente aos marmosets amazônicos do que aos da mata Atlântica. Estes resultados reabrem a discussão sobre diversidade e programas de conservação baseados apenas em classificações taxonômicas tradicionais.

Knowledge and culture: two significant issues for local level development programme analysis

O artigo objetiva propor um arcabouço teórico para analisar programas de desenvolvimento e suas ações em nível local. Em particular, o artigo destaca dois conceitos-chave que devem ser levados em consideração no processo de implementação de programas de desenvolvimento em nível local: conhecimento e cultura. O artigo mostra que o entendimento do conhecimento enquanto construção social contrasta com a perspectiva racional e positivista de que este é derivado exclusivamente da ciência. O artigo mostra que se desenvolvimento é relacionado para a melhoria das condições de vida das pessoas por via de mudanças econômicas e sociais, então, desenvolvimento é mediado e impacta sobre conhecimento e cultura.

The effect of exogenous fibrolytic enzymes and a ferulic acid esterase-producing inoculant on the fibre degradability, chemical composition and conservation characteristics of alfalfa silage

The objective of this study was to determine the effect of applying fibrolytic enzymes at ensiling, either alone or in combination with a ferulic acid esterase-producing bacterial silage inoculant, on the silage conservation characteristics and nutritive value of alfalfa (Medicago sativa L). Second-cut alfalfa (340 g DM/kg fresh crop) was harvested, wilted, chopped and sub-sampled into 24 batches. Samples were randomly allocated in triplicate to one of four enzyme product treatments supplying endoglucanases and xylanases: none (control), EN1, EN2, EN3; applied alone or in combination with a ferulic acid esterase-producing silage inoculant (FAEI). Treatments were arranged in a 4 x 2 factorial design. All enzyme treatments were applied at 2 ml enzyme product/kg herbage DM, and inoculant was applied at 1 x 10(5) cfu/g fresh herbage. Samples were packed into laboratory-scale silos and stored for 7, 27 or 70 days, and analysed for dry matter (DM) losses, aerobic stability, chemical composition and in vitro ruminal degradability. The use of enzymes did not affect (P>0.05) ensilage DM losses or lactic or acetic acid concentrations after 70 days of ensilage, compared to the control silage. Silage produced using EN1 had lesser neutral detergent fibre (aNDF, P=0.046) and acid detergent fibre (ADF; P=0.006) concentrations than control silage. However, no difference (P>0.05) was observed between the control silage and silage produced with EN1 for aNDF or ADF degradability (NDFD, ADFD). Silages produced with FAEI had greater DM losses (P=0.017) and pH (P<0.001) and lesser NDFD (P=0.019), ADFD (P=0.010) and proportion of lactic acid in the total fermentation products (P=0.006) after 70 days of ensilage, compared to uninoculated silages. The use of fibrolytic enzymes did not have a major effect on the ensilage fermentation of alfalfa, either ensiled alone or with an inoculant. No advantage in ruminal DM or fibre degradability was observed for silages produced with fibrolytic enzymes. The use of a ferulic acid esterase-producing inoculant alone did not improve the nutritive value of alfalfa silage, and did not promote any incremental effects when applied in combination with fibrolytic enzyme products.
