Long-term agricultural sustainability is dependent in part on our capacity to provide productive, nutritious crops that minimize the negative impacts of agriculture on the landscape. Perennial grains within an agroforestry context offers one solution: These plants produce large root systems that reduce soil erosion and simultaneously have the potential to produce nutrients to combat malnutrition. However, nutrient compositions of wild, perennial, herbaceous species, such as those related to the common bean (Phaseolus vulgaris) are not well known. In this study, seed ion and amino acid concentrations of perennial and annual Phaseolus species were quantified using ionomics and mass spectrometry. No statistical difference was observed for Zn, toxic ions (e.g., As) or essential amino acid concentrations (except threonine) between perennial and annual Phaseolus species. However, differences were observed for some nutritionally important ions. For example, Ca, Cu, Fe, Mg, Mn, and P concentrations were higher in annual species; further, ion and amino acid concentrations appear to be largely independent of each other. These results suggest variability in ion and amino acid concentrations exist in Phaseolus. As new crop candidates are considered for ecological services, nutritional quality should be optimized to maximize nutrient output of sustainable food crops.

ABSTRACTMalnutrition is a global public health concern and identifying mechanisms to elevate the nutrient output of crops may minimize nutrient deficiencies. Perennial grains within an agroforestry context offers one solution. The development and integration of perennial crops for food has critically influenced dialogue on the ecological intensification of agriculture and agroforestry. However, the nutrient compositions of wild, perennial, herbaceous species, such as those related to the common bean (Phaseolus vulgaris) are not well known. In this study, seed amino acid and ion concentrations of perennial and annualPhaseolusspecies were quantified using ionomics and mass spectrometry. No statistical difference was observed for Zn, toxic ions (e.g. As) or essential amino acid concentrations (except threonine) between perennial and annualPhaseolusspecies. However, differences were observed for some nutritionally important ions among and within lifespan groups. Ca, Cu, Fe, Mg, Mn, and P concentrations were higher in annual species. Intraspecific variability in ion concentrations and amino acids was observed within species; further, ion concentrations and amino acids differ among annual species and among perennial species. Ion and amino acid concentration appear to be largely independent of each other. These results suggest variability in ion and amino acid concentrations exist in nature. As new crop candidates are considered for ecological services, nutritional quality should be optimized to maximize nutrient output of sustainable food crops.

Amino Acid Concentrations

Nutrient intake during pregnancy affects foetal development and placental function in a range of species, often with long-term effects on offspring viability. Maternal supply and placental transport of amino acids are key to delivering amino acids for foetal metabolism. Maternal under-nutrition has been shown to reduce both maternal and foetal amino acid concentrations even after a period of re-feeding (Kwon et al. 2004). Intriguingly whether sheep have been adapted to a harsh environment or not appears to influence the extent of any reduction (Jobgen et al. 2008). The present study therefore tested whether plasma amino acid concentrations differed between Scottish Blackface (B) sheep adapted to a hill environment and a lowland breed (Suffolk, S) selected for lean tissue growth when challenged by a period of under-nutrition.

1. We have investigated the effects of moderate long-term exercise on protein turnover in fed man by measuring the extent of whole-body nitrogen production, the labelling of urinary ammonia from ingested [15N]glycine and plasma, muscle and urine free amino acid concentrations. 2. Judged both from nitrogen production, and from the extent of 13CO2 production from ingested l-[l-13C]leucine, exercise causes a substantial rise in amino acid catabolism. 3. Amino acids catabolized during exercise appear to become available through a fall in whole-body protein synthesis and a rise in whole-body protein breakdown. After exercise, protein balance becomes positive through a rise in the rate of whole-body synthesis in excess of breakdown. 4. Studies of free 3-methylhistidine in muscle, plasma and urine samples suggest that exercise decreases the fractional rate of myofibrillar protein breakdown, in contrast with the apparent rise in whole-body breakdown.

This book critically engages the shortcomings of the field of international heritage law, seen through the lenses of the five major UNESCO treaties for the safeguarding of different types of heritage. It argues that these five treaties have, by design or in their implementation, effectively prevented local communities, who bear the brunt of the costs associated with international heritage protection, from having a say in how their heritage is managed. The exclusion of local communities often alienates them not only from international decision-making processes but also from their cultural heritage itself, ultimately meaning that systems put in place for the protection of cultural heritage contribute to its disappearance in the long term. The book adds to existing literature by looking at these UNESCO treaties not as isolated regimes, which is the common practice in the field, but rather as belonging to a discursive continuum on cultural heritage. Rather than scrutinizing the regimes themselves, the book focuses on themes that cut across the relevant UNESCO regimes, such as the use of expert rule in international heritage law, economics, and the relationship between heritage and the environment. It uses this mechanism to highlight the blind spots and unintended consequences of UNESCO treaties and how choices made in their drafting have continuing and potentially negative impacts on how we think about and safeguard heritage. The book is of interest to cultural heritage scholars and practitioners across all disciplines, as well as to international lawyers interested in the dynamics of fragmented subfields.
