Stress‐gradient framework for green roofs: Applications for urban agriculture and other ecosystem services
2023Andrés G. Rolhauser, J. Scott MacIvor, Adriano N. Roberto, Selena Ahmed, Marney E. Isaac · Ecological Solutions and Evidence · Global
This paper addresses the limited understanding of conditions under which stress-tolerant "nurse" plants can facilitate stress-intolerant "protégé" species on extensive green roofs for urban agriculture. It proposes a framework and linear model, integrating trait–environment theory and facilitation ecology, to make testable predictions on protégé species performance along stress gradients. The framework aims to help researchers assess the feasibility of nurse–protégé interactions under various environmental conditions.

2023Pengyao Li, Feinan Lyu, Yuan Zhou, Zhenrong Yu · Ecological Indicators · China (Beijing)
A study in Beijing, China, surveyed ground spiders and carabids in 12 plantation forests and nearby arable lands to assess the impact of afforestation on biodiversity. Intensive afforestation on arable lands did not increase local ground arthropod diversity. Ground arthropod abundance and species richness in plantation forests were significantly lower than in arable lands when surrounding arable land cover was relatively high, and overall landscape-scale diversity was not improved.

2023Angela Oulton, Susan Jagger · · North America
A discourse analysis of historical school garden texts in North America reveals that school gardens have not been welcoming or accessible to all children, despite persuasive research on the positive effects of nature-based learning. Historically, school gardens were used to serve adult agendas, including containing urban children, assimilating marginalized groups, and creating laborers, thereby reinforcing patriarchal, colonial, white supremacist, and eugenic aspirations. This study explores how these discourses culturally constructed childhoods and influenced children.

2023Leigh Whittinghill, Major Ballard, Anju Chaudhary, Smriti Kandel, Caitlin Mullins, Pradip Poudel · HortScience · United States
This study analyzed runoff water quality from four different nutrient management treatments (conventional fertilizer, organic fertilizer, low-compost + organic fertilizer, and high compost) in raised beds and small plastic pool container plots in the United States. Water samples, collected monthly, were analyzed for pH, conductivity, color, turbidity, nitrate-nitrogen, ammonia-nitrogen, total phosphorus, and potassium. While significant differences existed between raised beds and container plots, these did not translate to meaningful water quality differences for most variables, except for nitrate-nitrogen. The conventional fertilizer treatment showed greater or more variable nutrient leaching than other treatments.
