Legacy phosphorus (P) is a concept advanced by Dr. Andrew Sharpley and colleagues that was originally applied to the persistence of anthropogenic signatures in watersheds, and it has since been adopted in a diversity of settings to help guide the science and management of P. Following Sharpley's example to develop consensus-based science, we considered contrasting perspectives on legacy P and defined legacy P as those stores within the environment that arise from historic human activity excluding "natural" or "background" geogenic sources.

Article Synopsis
  • - Phosphorus runoff from agriculture contributes significantly to freshwater eutrophication, and riparian zones are used to mitigate this by retaining phosphorus before it reaches streams.
  • - A study examined 8 riparian zones in Canada to analyze how factors like topography, frost severity, and vegetation type affect phosphorus release during winter, by measuring soil and vegetation phosphorus levels in various locations and seasons.
  • - Findings indicated that while phosphorus levels were higher at field edges and increased with frost severity in lab conditions, field results showed no strong link between phosphorus changes and frost or inundation; harvesting vegetation reduced phosphorus levels in floodwater.

Phosphorus (P) loss from agricultural systems to surface waters, and ultimately, eutrophication, presents a wicked problem requiring transdisciplinary solutions. The mission of SERA-17 (Southern Extension and Research Advisory Information Exchange Group-17) has been to address this problem by developing "Innovative Solutions to Minimize Phosphorus Losses from Agriculture." Over the course of his career, Dr.

Background: McArdle disease is caused by myophosphorylase deficiency leading to blocked glycogenolysis in skeletal muscle. Consequently, individuals with McArdle disease have intolerance to physical activity, muscle fatigue, and pain. These symptoms vary according to the availability of alternative fuels for muscle contraction.
