“…The selection of plant species to cultivate in outside home spaces should be based primarily on their ability to cope with the harsh conditions of the urban environment, such as high wind and irradiance, lack of organic material and nutrients, and intermittent drought (Pavao-Zuckerman 2008). Therefore, careful plant selection should be integrated into outside space design (Lee et al 2014;John et al 2016;Chaudhary et al 2019). Urban habitats are unique and harsh environments for established plant communities, largely because of increased abiotic stresses, such as disturbance, pollution, drought, radiation, heat and microclimate extremes, but also because of the reduction of colonization and modifications in soil microbial diversity (e.g., mycorrhizas or bacteria).…”

People are facing uncertain and difficult times in the face of the Covid-19 pandemic. The benefits of plants (psychological, health, economic, productive) in this period of forced isolation can be of key importance. If many of us have to self-isolate in urban or suburban environments, we need something to do to keep our bodies and minds active and fed. In such a challenging scenario, a vegetable garden in home spaces can bring recreational, health, economic and environmental benefits. Regardless of the Covid-19 pandemic, there is untapped potential for this kind of garden to impact environmental outcomes, public awareness, and market trends. Home vegetable gardens could provide a small-scale approach to the sustainable use of natural resources, leading towards self-sufficiency, self-regulation, sustainability, and environmental protection.

“…This study suggests a potential mechanism for the observed passive reestablishment and gradual increase in abundance of AM fungi in a highly urbanized environment (Chaudhary et al ., 2019). Comparatively little research has been conducted in cities on arbuscular mycorrhizas, important symbioses for plants in urban ecosystems with the potential to enhance urban ecosystem services and sustainability (Cousins et al ., 2003; John et al ., 2017; Gupta et al ., 2018; Gerz et al ., 2019).…”

Summary Dispersal is a key process driving local‐scale community assembly and global‐scale biogeography of plant symbiotic arbuscular mycorrhizal (AM) fungal communities. A trait‐based approach could improve predictions regarding how AM fungal aerial dispersal varies by species. We conducted month‐long collections of aerial AM fungi for 12 consecutive months in an urban mesic environment at heights of 20 m. We measured morphological functional traits of collected spores and assessed aerial AM fungal community structure both morphologically and with high‐throughput sequencing. Large numbers of AM fungal spores were present in the air over the course of 1 yr, and these spores exhibited traits that facilitate aerial dispersal. Measured aerial spores were smaller than average for Glomeromycotinan fungi. Trait‐based predictions indicate that nearly one third of described species from diverse genera demonstrate the potential for aerial dispersal. Diversity of aerial AM fungi was relatively high (20 spore species and 17 virtual taxa), and both spore abundance and community structure shifted temporally. The prevalence of aerial dispersal in AM fungi is perhaps greater than previously indicated, and a hypothesized model of AM fungal aerial dispersal mechanisms is presented. Anthropogenic soil impacts may liberate AM fungal propagules initiating the dispersal of ruderal species.
