A healthy meal is a complex cocktail of macroand micro-nutrients. Yet, when it comes to discussing diets, we typically consider calories to be the central drivers of hunger and obesity, disregarding other factors. The threat that climate change poses to agricultural productivity and food security around the world, especially in the tropics and sub-tropics, is also usually analysed only in terms...
Although agriculture is crucial to economic growth in South Africa, the industry faces several challenges, including effects of pests and diseases that contribute crop loss. Such losses severely affect maintenance food security. Therefore, a major challenge finding effective, environmental-friendly control measures for insect pests. Potatoes are among four most widely consumed vegetable crops w...
This study designed and validated a questionnaire aimed at examining parental feeding styles to encourage healthy eating habits among Costa Rican adolescents. Adolescents (n=133; mean age 15.4 years), and their parents, participated in the study. The parents completed a parental feeding style questionnaire, and the adolescents completed 3-day food records. Confirmatory factor analyses suggest f...
Climate change causes new patterns of crops, cultivation and humans and animal disease, and affectation new risks for food security, safety and human health. Effects of climate change may be positive or negative, resulting from the complex interactions of temperature and precipitation (1). World Health Organization (WHO) defines food security as " when all people at all times have access to suf...
Background and Objectives: Food insecurity may be associated with poor nutrition, which in turn can increase the risk of adverse nutrition and health outcomes among infants and toddlers. This study was undertaken in 2008 to gain an insight of mothers' views on complementary feeding practices and food security. Materials and Methods: In this qualitative study, data were collected through 10 Foc...
The interaction between plant-aphid is phenomenal and complex. Aphids possess efficient mouthparts which feed on plant sap intensively. Adaptation to host plants successful feeding achieved through the strategic ability of aphids reproduce sexually asexually (parthenogenesis). Aphid infestation damages in diverse ways induces defense. Though elicit direct indirect defense resist aphid feeding, ...
The base cause of disrupted diets is thought to be pollution— in the atmosphere (e.g., human-driven carbon dioxide emissions), on land, and in water—as well as modifications to natural landscapes for human use. To test this idea, scientists closely monitor the diets of animals. Then, an animal’s gut content or faeces can be examined to identify ingested items and quantify energetic and nutritio...

Crop-raiding is a major source of conflict between people and wildlife globally, impacting local livelihoods and impeding conservation. Conflict mitigation strategies that target problematic wildlife behaviours such as crop-raiding are notoriously difficult to develop for large-bodied, cognitively complex species. Many crop-raiders are generalist feeders. In more ecologically specialised specie...
Food web linkages, or the feeding relationships between species inhabiting a shared ecosystem, are an ecological lens through which ecosystem structure and function can be assessed, and thus are fundamental to informing sustainable resource management. Empirical feeding datasets have traditionally been painstakingly generated from stomach content analysis, direct observations and from biochemic...
