Abstract:

Good nutrition is vital for adolescents, because it supports their growth and helps them to become healthy adults. Under-nutrition delays adolescents’ physical and mental growth and maturation, and reduces adolescents’ learning and working capacity. Meanwhile, over-nutrition in adolescence, together with an unhealthy lifestyle, can lead to overweight and obesity, which are risk factors for many chronic diseases such as coronary heart disease, type 2 diabetes, and stroke. However, nutrition problems in adolescents are both common and serious in developing countries, especially in the rural area

Abstract:

From the Arctic to the South Pacific, Indigenous Peoples have experienced a rapid nutrition transition involving the decline of traditional/subsistence-based ways of life and the adoption of a “Western” diet that is high in saturated fats, sugar, and processed foods. This dietary shift has been paralleled by an increased prevalence of obesity, diabetes, and, other diet-related chronic diseases. In the Arctic, rapidly changing biophysical conditions, globalization, and integration into market economies are collectively challenging access to both country foods and nutritious market foods.

Abstract:

This thesis examines the impact of seasonal and inter-annual variations in rainfall on food supply and disease environment, and hence the biological welfare of savannah populations in southern Zimbabwe. Ecological dynamics are thought to determine the impact of rainfall, and this hypothesis is tested through the comparison of populations either side of a major ecological boundary between heavy clay rich and sandy soils. Due to differences in soil-moisture productivity relations, and the level and form of ecological heterogeneity, the sandveld environment shows much less seasonal and inter-annu

Abstract:

Growing rates of childhood obesity continue to be a major public health issue for this country. In order to impact childhood obesity at the population level it is necessary to shift our focus away from individual behaviors and towards the critical examination of the role that settings have in promoting or discouraging healthy eating. One relevant setting in the fight against childhood obesity is the school cafeteria. Since 1946, the National School Lunch Program has worked to ensure that schools can provide their students with affordable daily access to nutritional, well-balanced meals. Howeve

Gypsophile species are edaphic endemics of gypsum soils, and they are considered specialists of this stressful substrate. Gypsum endemics from different families and regions of the world tend to show a unique leaf elemental composition, similar to the chemical characteristics of gypsum soils. However, the ecological significance of their unique foliar composition remains unknown. The factors underlying the ecological amplitude of gypsophiles remain also poorly studied. The main literature is based on the distribution of gypsophiles linked to gypsum soils in drylands, although some studies sugg

Childhood malnutrition is a growing public health challenge for low- and middle-income countries. Globalization and urbanization have led to a significant shift in dietary habits and physical activity patterns over the past few decades, resulting in the coexistence of undernutrition and overnutrition within populations. The negative health, development, and social impacts of childhood malnutrition are serious and ongoing for individuals and their families, while also contributing an economic burden to these countries.

Abstract:

Climate change is predicted to impact organismal nutritional ecology. Increased temperatures can directly accelerate physiological rate processes, which in turn, impact nutritional requirements. Climate change can also impact organisms indirectly by altering the quality and quantity of nutritional resources, creating the potential for nutritional mismatch between what nutrients are available in the environment and what organisms require. Investigation of organismal stoichiometry, particularly the balance of carbon, nitrogen, and phosphorus content of organisms, can help illuminate the extent t

La riflessione pedagogica è chiamata ad offrire un’interpretazione complessa del rapporto tra visioni antropologiche ed emergenze educative per elaborare nuove reti di conoscenza e azione nella prospettiva del bene comune e della sostenibilità della vita.

Abstract:

Biodiversity is expected to be an assurance for agroecosystem resilience because it seems fundamental to preserve basic ecosystem services (ES). To examine in depth these topics, the present research aims: a) to evaluate, in real farms, the environmental sustainability by measuring the efficiency of some key ES in agroecosystems with different management; b) to search for relationships among biodiversity groups and ES and c) to explore the existence of correlations between different bioindication methodologies. The basic hypothesis is that a high efficiency of the ES can improve the environmen

Abstract:

The current population growth will demand a higher productive agriculture to full the food requirement. To supply this need and preserve the environment, many resources are applied to promote sustainable agriculture. Phosphorus depletion is the main factor that limits crops yields in tropical soils, where the pH and clay content rapid fixate this nutrient. Plant breeders aim to solve this issue by changing the plant requirements for phosphorus and adapting them to low P availability. However, with these approaches the demand for phosphorus fertilizers will continue and so the depletion of the

Existem poucas informações sobre exigências de energia de cervídeos brasileiros, dificultando o sucesso de manejo e reprodução em cativeiro. O conhecimento das exigências de energia também é importante para determinar os recursos necessários para sua conservação em parques e reservas. O primeiro objetivo deste experimento foi estudar as exigências nutricionais do veado catingueiro (Mazama gouazoubira) em cativeiro. O segundo objetivo foi observar o comportamento alimentar do veado-campeiro (Ozotoceros bezoarticus) no Parque Nacional das Emas (PNE), descrevendo qualitativamente e quantitativam

Em nossa espécie, entre as estratégias adaptativas relevantes, encontra-se a migração, que permitiu ao ser humano ocupar novos ambientes, em busca de condições de vida melhores que as possíveis ou acessíveis em seu local de origem. Atualmente, a migração se constitui, no sentido genético, no principal fator evolutivo da espécie humana. Condições de vida adversas tendem a se refletir na capacidade de obtenção de alimentos. As crianças de uma população são particularmente sensíveis, refletindo-se facilmente em seu desenvolvimento físico, deficiências ou privações alimentares. Em trabalho

O presente trabalho investigou a dieta adotada por populações humanas, rural e urbana de Piracicaba, SP. Foi abordada a adaptabilidade humana, em relação à capacidade de uma população se adaptar a mudanças nutricionais, geralmente decorrentes de outras mudanças em seu ambiente. O indicador da adaptabilidade humana adotado foi o estado nutricional das mães de pré-escolares, dado que essas apresentam grande influência nos hábitos alimentares de toda a família. Dessa forma, tal população alvo é relevante em relação à população como um todo. O estado nutricional foi analisado a partir do peso e es
