Mixed effects of urbanization on pollination services among four native plant species Open
The pollination services provided by insects maintain ecosystem functioning and services in urban green spaces. Most research investigates rural to urban gradients where it is found that pollination services are often greater in urban gree…

Mail-order solitary bee cocoons as a gateway for biological invasion Open
The unregulated online trade of solitary bee cocoons, particularly mason bees (Osmia spp.), poses growing risks to biodiversity. Marketed as tools to enhance pollination, these mail-order cocoons can include non-native species, including i…

Assessing the effects of mowing intensity on the overwintering stem‐dwelling insect community of <i>Solidago altissima</i> L. (Asterales: Asteraceae) Open
Mowing is a commonly used and necessary practice in the management of urban meadowscapes. However, mowing is also a source of mortality for insects in these meadowscapes. In this study, we examined how changes in mowing intensity for mows …

Pollinator visits increase with bloom amount but decline with building height on extensive green roofs Open
Green roofs provide foraging and nesting resources for pollinators that would otherwise be absent. However, green roofs are isolated from ground level, limiting habitat to only species that can reach them. In Eastern North America, green r…

Plant cover and biomass change on extensive green roofs over a decade and ten lessons learned Open
Green roofs are well studied for the environmental, social, and economic services these provide. As a result, green roofs are widespread and within the common vernacular of city residents. Green roof bylaws and construction standards are p…

The great urban shift: Climate change is predicted to drive mass species turnover in cities Open
Human experiences with nature are important for our culture, economy, and health. Anthropogenically-driven climate change is causing widespread shifts in biodiversity and resident urban wildlife are no exception. We modelled over 2,000 ani…

Nature-based solutions and biodiversity: synergies, trade-offs, and ways forward Open
The provision of nature-based solutions (NBS) and the conservation of biodiversity are two aims of urban research, planning, and policy. A key question is whether these aims form synergies or conflict with each other. Controlled experiment…
