25. As dinâmicas de Schefflera angustissima (March.) Frodin (Araliaceae) e de Andira anthelmia (Vell.) March. (Fabaceae) na reserva de Morro Grande, São Paulo. / The dynamics of Schefflera angustissima (March.) Frodin (Araliaceae) and Andira anthelmia (Vell.) March. (Fabaceae) in the Morro Grande reserve, São Paulo.
Population dynamics deals with variation in time and space in the density and abundance of populations. The studies about the dynamics of tropical rain forest tree species, in particular, have become popular only about 1970, when the extinction risks for species of economic interest became pressing. Because the Brazilian biomes are being destroyed progressiv

26. Fenóis totais no cafeeiro em razão das fases de frutificação e do clima. / Total phenols in the coffee tree due to the fructification phases and the climate.
The vegetables show a natural defense against external factors, biotic and abiotic, by the synthesis of the phenolic compounds in the secondary metabolism, which varies with the maturity state and with the climate. The increase of phenolic compounds in the plants is directly related to the resistance to the infection thought pathogens and insect infestation.

27. Sistema de suporte à tomada de decisão para o manejo fitossanitário nos Campos Gerais do Paraná
Climate factors influence the occurrence of plant diseases. The objective of this work was to develop a decision support system for plant disease management and control, through the monitoring of the climatic variations and determine the risk of occurrence of plant diseases epidemics. For the decision support system a software was developed (Arc-Epidemic - A

28. Global Change and Human Vulnerability to Vector-Borne Diseases
Global change includes climate change and climate variability, land use, water storage and irrigation, human population growth and urbanization, trade and travel, and chemical pollution. Impacts on vector-borne diseases, including malaria, dengue fever, infections by other arboviruses, schistosomiasis, trypanosomiasis, onchocerciasis, and leishmaniasis are r

31. Why tropical forest lizards are vulnerable to climate warming
Biological impacts of climate warming are predicted to increase with latitude, paralleling increases in warming. However, the magnitude of impacts depends not only on the degree of warming but also on the number of species at risk, their physiological sensitivity to warming and their options for behavioural and physiological compensation. Lizards are useful

32. Occupational health problems among migrant and seasonal farm workers.
Migrant and seasonal farm workers are one of the most underserved and understudied populations in the United States. The total US population of such farm workers has been estimated at 5 million, of whom about 20% live or work in California. Farm workers perform strenuous tasks and are exposed to a wide variety of occupational risks and hazards. Low socioecon

33. Niches, models, and climate change: Assessing the assumptions and uncertainties
As the rate and magnitude of climate change accelerate, understanding the consequences becomes increasingly important. Species distribution models (SDMs) based on current ecological niche constraints are used to project future species distributions. These models contain assumptions that add to the uncertainty in model projections stemming from the structure

34. Health and safety problems associated with long working hours: a review of the current position.
The European Community Directive on Working Time, which should have been implemented in member states of the European Community by November 1996, contains several requirements related to working hours, including the right of employees to refuse to work more than 48 hours a week. The United Kingdom government attempted to oppose the Directive, arguing that th
