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.

The literature on professional socialization focuses on how students adopt and internalize professional identities and values, and assumes that boundary work is essential to learning how best to practice their profession. However, a focus on boundary work in the context of midwifery training - which is embedded in the gendered and hierarchical landscape of maternity care - is lacking. Thus, this article examines how Canadian student-midwives learn to navigate and negotiate interprofessional boundaries.

Unlabelled: Wetlands cover a small portion of the world, but have disproportionate influence on global carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes. However, the underlying biogeochemical processes that affect wetland C pools and fluxes are complex and dynamic, making measurements of wetland C challenging. Over decades of research, many observational, experimental, and analytical approaches have been developed to understand and quantify pools and fluxes of wetland C.

Cyanobacterial blooms pose a significant threat to water security, with anthropogenic forcing being implicated as a key driver behind the recent upsurge and global expansion of cyanobacteria in modern times. The potential effects of land-use alterations and climate change can lead to complicated, less-predictable scenarios in cyanobacterial management, especially when forecasting cyanobacterial toxin risks. There is a growing need for further investigations into the specific stressors that stimulate cyanobacterial toxins, as well as resolving the uncertainty surrounding the historical or contemporary nature of cyanobacterial-associated risks.

Article Synopsis
  • The rise of cyanobacterial blooms in global water bodies highlights the necessity for improved management tools, including the reconstruction of historical cyanobacterial data and understanding the environmental factors that contribute to their prevalence.
  • A study compared a new method using visible near-infrared reflectance spectroscopy (VNIRS) for estimating cyanobacterial abundance in lake sediments against the traditional real-time PCR (qPCR) technique across 30 different lakes.
  • Results showed that VNIRS is effective for analyzing recent cyanobacterial trends, with a significant correlation to qPCR results in 76% of the lakes, but also indicated the need for refinement in cases where the VNIRS technique did not perform as strongly.
