Health-related physical fitness is associated with selected sociodemographic an...
Guedes, Dartagnam Pinto; Neto, J.M.; Lopes, Vítor P.; Silva, A.J.This study investigated the association between sociodemographic and behavioral factors and health standards based on physical fitness component scores in a sample of Brazilian schoolchildren. Methods: A sample of 1457 girls and 1392 boys aged 6 to 18 years performed a test battery of 5 items: 1) sit-and-reach, 2) curl-up, 3) trunk-lift, 4) push-up, and 5) progressive endurance run (PACER). The cut-off scores f...
Silage quality of Brachiaria brizantha cultivars ensiled with different levels ...
Costa,K.A.P; Assis,R.L; Guimarães,K.C; Severiano,E.C; Assis Neto,J.M; Crunivel,W.S; Garcia,J.F; Santos,N.FThe silage quality of Brachiaria brizantha cultivars ensiled with different levels of millet meal was evaluated. The experimental design was a completely randomized with three replications in a factorial 3 x 4, with three cultivars of Brachiaria brizantha: marandu, xaraés, and piatã and four levels of millet meal 0, 5, 10, and 15%. The addition of millet meal improved the quality of B. brizantha silage. The inc...

Patrício, Joana; Adão, Helena; Neto, J. M.; Alves, Ana; Traunspurger, Walter; Marques, J.C.Do nematode and macrofauna assemblages provide similar ecological assessment information? To answer this question, in the summer of 2006, subtidal soft-bottom assemblages were sampled and environmental parameters were measured at seven stations covering the entire salinity gradient of the Mondego estuary. Principal components analysis (PCA) was performed on the environmental parameters, thus establishing differ...

Plantas medicinais utilizadas em comunidades rurais de Oeiras, semiárido piauiense
Oliveira,F.C.S.; Barros,R.F.M.; Moita Neto,J.M.O estudo foi realizado no período de fevereiro de 2007 a maio de 2008, em vinte e uma comunidades rurais do município de Oeiras (07º00'54''S e 42º08'06''W), localizadas em área de transição vegetacional Caatinga/Cerrado, onde predomina a Caatinga. Objetivou-se conhecer as plantas tradicionalmente utilizadas pela população com fins terapêuticos. As coletas botânicas seguiram metodologia usual e os exemplares ide...
Seasonal and spatial variability of nematodes and macrofauna assemblages in the...
Alves, Ana; Adão, Helena; Patricio, J.; Neto, J. M.; Vinagre, P.; Verissimo, H.; Marques, J. C.With the implementation of the European Water Framework Directive there is the need to develop assessment tools based on biological data, which are adequate for all European aquatic systems. Macrofauna communities have traditionally been used to assess and evaluate ecological integrity. However, meiofauna communities can also suitably reflect the ecological conditions present in a particular system. Free-livin...
Role of estuarine nematode assemblages in ecological assessment in a southern E...
Alves, Ana; Adão, Helena; Patricio, J.; Neto, J. M.; Marques, J. C.To improve nematode’s knowledge in the Mondego estuary (Portugal), the temporal and spatial variations of subtidal free-living marine nematodes communities (density, diversity and trophic structure) along the entire estuarine gradient (freshwater to euhaline areas) were seasonally studied (2006 to 2009). Since 1980, the hydromorphological, physicochemical and ecological responses of the system to both natural a...
Spatial distribution of subtidal Nematoda communities along the salinity gradie...
Adão, Helena; Alves, A.; Patricio, J.; Neto, J. M.; Costa, M. J.; Marques, J.C.of two Portuguese estuaries exposed to different degrees of anthropogenic stress: the Mira and the Mondego. The nematode communities were mainly composed of Sabatieria, Metachromadora, Daptonema, Anoplostoma, Sphaerolaimus and Terschellingia species, closely resembling the communities of Northern European estuaries. In both estuaries, nematode density and community composition followed the salinity gradient, n...
Nematodes vs Macrofauna assemblages along an estuarine gradient (Mondego estua...
Adao, Helena; Patricio, J.; Alves, Ana; Neto, J. M.; Teixeira, H.; Marques, J.C.The spatial distribution of the nematodes and macrofauna communities in the subtidal sediments along estuarine gradient in the Mondego estuary was studied. The main aim is to compare the response of the nematodes and macrofauna communities structure adjusted for each estuarine stretch. Spatial distribution of nematode assemblages followed the estuarine gradients, allowing to distinguish: The freshwater and olig...
Response of intertidal macrobenthic communities to long term human induced chan...
Paz, L. de; Neto, J. M.; Marques, J. C.; Laborda, A. J.Long term macrobenthos data together with physical habitat parameters were analysed to investigate spatial and temporal changes at an estuary under different anthropogenic pressures, mainly increasing shellfish farming. The aim was to assess the possible impacts of these pressures on the macrobenthic communities by comparing a period before and after changes in these pressures. Benthic samples were seasonally c...
