The cover shows a landscape view of part of an operational wind farm sited in mixed-grass prairie habitat in southeast Wyoming, USA. This was one of the field sites where footage was recorded for the study by Wischler et al., who explored how the proximity to wind turbines affected plant-pollinator dynamics.

Abstract:
Wind turbines influence several abiotic conditions in the environments they are sited in and may influence the behavior and movement of insect pollinators. It is unknown how operating turbines influence plant–pollinator interactions. To investigate if pollination dynamics could be affected by the presence of wind turbines, we recorded videos of pollinating insects visiting flowers on blooming, native plants within a wind energy facility, and at five sites located 4–28 km from operating turbines. We calculated the length of interactions between insect pollinators and flowers, and identified individual behaviors exhibited by visiting insects. Insects interacted with flowers for longer periods of time when closer to wind turbines. As distance to turbine increased, the probability that pollinating insects would crawl into blooms or drink nectar decreased, while the probability that they would rest on plants increased. These behaviors also varied with changes in wind speed, air temperature, and the number of flowers on plants. Our study is one of the first to offer evidence that plant–pollinator interactions could be altered by turbines or abiotic changes caused by turbines. This topic merits further investigation to help land managers and conservation organizations make informed decisions about future turbine siting, restoration, and conservation efforts.
Nordic Journal of Botany—who are we?
NORDIC JOURNAL OF BOTANY: An International Journal for Botany and Mycology is an Open Access journal owned by the Nordic Society Oikos.
We are an international journal publishing research on all aspects of plant and fungal ecology, evolution, conservation, biogeography, and taxonomy. We welcome cross-disciplinary research such as plant-pollinator interactions, human-plant relations, and plant-ecosystem connections. Our scope includes algae and bryophytes and all groups of fungi. We explore trending topics in plant sciences and publish research from both established experts and early-career researchers.
