Dietary segregation is essential for the coexistence of closely related species of animals. However, little is known about how changes in availability of food resources might affect trophic interactions of wild animals breeding in sympatry. Here, we examined how interannual variations in relative food availability (as reflected in blood levels of stress hormone corticosterone, CORT) affect food...

The paper discusses the importance of agriculture to a people, its economy and its place at achieving food security for nations, Nigeria Inclusive. Furthermore, it talked about food security and insecurity and its indices. It delved into prospects for increased agricultural production and how this can be achieved. Again, it discussed efforts that have been put in place by past Nigerian governme...

Food security is a growing societal challenge. The pressure to feed projected global population of 9.6 billion by 2050 will continue be limited decreasing arable land. recent disruptions in international trade resulting from responses the COVID-19 pandemic have highlighted importance regional self-reliance food production. While Canada highly self-reliant categories such as meat and dairy, nati...

Food production in 2050 will be sufficient, globally, but many of the poor will remain food insecure. The primary cause of food insecurity will continue to be poverty, rather than inadequate food production. Thus, policies and investments that increase the incomes of the poor will remain the best ways to extend food security to all. Investments that promote growth in sustainable agriculture and...

We examined developmental and behavioural plasticity of sand martin (Riparia riparia) nestlings hand-reared under laboratory conditions. We created six broods of six 4-day-old nestlings and randomly assigned them to one of the two following feeding regimens, each lasting for 3 days: (1) all nestmates fed a similar, limited amount of food (FR nestlings). This simulated synchronous hatching under...

Food losses in the developing world are thought to be 50% of the fruits and vegetables grown and 25% of harvested food grain (Burden, 1989). Food preservation can reduce wastage of a harvest surplus, allow storage for food shortages, and in some cases facilitate export to high-value markets. Drying is one of the oldest methods of food preservation. Drying makes produce lighter, smaller, and les...

What we eat is rapidly becoming an issue of global concern. With food shortages, the rise in chronic disease, and global warming, the impact of our dietary choices seems more relevant today than ever. Globally, a transition is taking place toward greater consumption of foods of animal origin, in lieu of plant-based diets. With this transition comes intensification of animal agriculture that in ...

This is a review of the results reported by studies on the impact of the Tibetan Plateau uplift on the body size, external organs, auditory organ and sexual dimorphism of animals. In high-altitude areas, strong selection pressures, such as low temperature, oxygen deficit, high frequency of strong winds, long periods of animal inactivity, and food shortages, have led to reduction in animal size,...

The HIV/AIDS pandemic threatens economic, social, and environmental sustainability throughout sub-Saharan Africa. This paper reports on a qualitative study exploring interrelationships between HIV/AIDS, labor availability, agricultural productivity, household resources, food consumption, and health status in rural southeastern Uganda. Respondents reported an increase in widow-and-orphan-headed ...
