| The present study was conducted in Kangra district of Himachal Pradesh (India) to study the physiological workload of respondents engaged in plucking tea leaves and identify the major causes and consequences of physiological stress. Majority of the respondents had ectomorph body with average physical fitness. During plucking tea leaves, the body of women workers deviate from natural alignment due to varying height of tea bushes. Hence, a continuous awkward standing posture, adverse environment and working conditions increase drudgery and decrease productivity of women workers. The change in environment temperature caused significantly higher physiological stress to the workers. At average working heart rate values during complete cycle of plucking, the... |

| Vochysia divergens Pohl (commonly known as cambara) is a pioneer tree species that is native to the Amazon Basin but has been invading the seasonally flooded wetlands of the Brazilian Pantanal, forming monospecific communities. The physiological aspects associated with cambara invasion, including the effects of flooding and shading on growth and leaf gas exchange, are unknown but may shed light on why cambara is able to invade this novel habitat so rapidly. Thus, we conducted a manipulative experiment to quantify the effects of shading and flooding on the growth, gas exchange and leaf nutrient content of V. divergens saplings. Based on previous research we hypothesized that (1) experimental flooding would have no effect on the growth and gas exchange of V.... |

| The present study evaluated the effectiveness of Amazonian nut (Bertholletia excelsa) as an alternative source of vegetal protein in tambaqui (Colossoma macropomum) diet. Performance and physiological status of fish fed for 60 days were evaluated. Four experimental isonitrogenous diets with 36% crude protein were formulated with increasing levels of nut meal (0, 10, 20 and 30%). Results showed the same growth performance for fish fed with diet with different levels of Amazonian nut than that without this ingredient (control). Analysis of physiological parameters (hematocrit, erythrocyte number, hemoglobin concentration, hematimetric indexes, total plasma protein and plasma glucose) corroborate these results, with no significant differences among... |
