Fauna of euglossina (Hymenoptera: Apidae) from southwestern Amazonia, Acre, Brazil
Male orchid bees were collected between December 2005 and September 2006 in 11 forest areas of different sizes in the region of Rio Branco, Acre, Southwestern Amazonia, Brazil. The bees were attracted by 6 aromatic compounds and collected by insect nets and scent baited traps. A total of 3,675 males of Euglossina in 4 genera and 36 species were collected. Eulaema cingulata (Fabricius) was the most common (24.6%), followed by Eulaema meriana (Olivier) (14.6%), Euglossa amazonica Dressler (10.5%), Eulaema nigrita Lepeletier (10.5%) and Eulaema pseudocingulata (Oliveira) (7.2%). Cineole was the scent that attracted the greatest number of individuals (23.8%) and methyl salicylate the greatest number of species (28) for both methods of sampling. Thirty one bees of 9 species with pollinar orchid attached to their bodies were collected. The accumulative number of species stabilized after the 48th collection. Few species were abundant; the great majority were represented by less than 50 bees. The lack of standardized sample protocols limited very much the conclusions derived from comparisons among the majority of studies on Euglossina assemblages. However, the results presented here suggest that the State of Acre is very rich in those bees compared to other regions.Machos de abelhas Euglossina foram coletados entre dezembro de 2005 e setembro de 2006 em 11 ĂĄreas florestais de diferentes tamanhos na regiĂŁo de Rio Branco, Acre, AmazĂŽnia Sul-Ocidental. As abelhas foram atraĂdas por 6 substĂąncias odorĂferas e coletadas com rede entomolĂłgica e armadilhas. Um total de 3.675 machos de Euglossina pertencentes a 4 gĂȘneros e 36 espĂ©cies foi coletado. Eulaema cingulata (Fabricius) foi a espĂ©cie mais comum (24,6%), seguida por Eulaema meriana (Olivier) (14,6%), Euglossa amazonica Dressler (10,5%), Eulaema nigrita Lepeletier (10,5%) e Eulaema pseudocingulata (Oliveira) (7,2%). Cineol foi a substĂąncia que atraiu maior nĂșmero de indivĂduos (23,8%) e metil salicilato o maior nĂșmero de espĂ©cies (28) para ambos os mĂ©todos de coleta. Foram coletados 31 indivĂduos pertencentes a 9 espĂ©cies portando polinĂĄrios. O nĂșmero acumulado de espĂ©cies coletadas na regiĂŁo estabilizou a partir da 48ÂȘ coleta. Poucas espĂ©cies foram abundantes, a maioria representada por menos que 50 indivĂduos. A falta de um protocolo amostral padronizado tem limitado comparaçÔes entre trabalhos realizados em diferentes regiĂ”es. Contudo, os resultados aqui apresentados indicam que o Acre apresenta elevada riqueza dessas abelhas
Methodological description and preliminary results of a cohort study on the influence of the first 1,000 days of life on the childrenâs future health
Abstract The aim of this report is to describe general and methodological characteristics of a cohort study in southern Brazil (Coorte Brasil Sul), aimed at understanding the impact of the first 1,000 days of life on childrenâs health. It is a cohort study involving all children born in 2009 and their families living in the municipality of Palhoça, State of Santa Catarina, Brazil. Face-to-face interviews with parents at home using a structured questionnaire and childrenâs physical and clinical examinations at schools have been carried out. Cross-sectional analyzes, longitudinal comparisons and hierarquical regression analysis will allow understanding if the first 1,000 days of life can influence on 6-year-old childrenâs health. The Coorte Brasil Sul is in its retrospective phase together with the childrenâs physical data collection. Preliminary data (n=1270) related to nutritional status point to a high prevalence of overweight (16.4%) and obesity (15.5%). With the continuity of the study, it is expected to evaluate if the first phases of life can influence health during adolescence and in adult life, mainly in relation to chronic diseases
