When a sweet corn breeder reached out in 2021 to report severe injury from the herbicide tolpyralate, Marty Williams hoped it was a fluke isolated to a single inbred line. But two years later, after methodical field, greenhouse, and genetic testing, his new Pest Management Science study not only confirms sensitivity to tolpyralate in 49 sweet corn and field corn lines, but also reveals a new genetic vulnerability that may affect corn more generally.

Fairy circles, a nearly hexagonal pattern of bare-soil circular gaps in grasslands, initially observed in Namibia and later in other parts of the world, have fascinated and baffled scientists for years. Theories for their appearance range from spatial self-organization induced by scale-dependent water-vegetation feedback to pre-existing patterns of termite nests.

Trees planted in urban areas can provide shade and contribute to a lower air temperature. For these services to be optimal, it is important to let asphalt give way to trees, according to research from the University of Gothenburg. The role of trees in the urban climate is an issue that has grown in importance in the wake of climate change, where average temperatures are expected to rise.

Tree height is an important indicator of a forest’s maturity and overall health. Forest restoration projects rely on tree height as a predictor and measurement of success, but forecasting a forest’s future tree height based on observations alone is almost impossible. There are too many factors that contribute to the growth and health of trees.

Scientists from Stockholm University have investigated the mechanisms that create cool microclimates beneath forest canopies during warm and dry summer days. The study reveals how canopy shading and water evaporation together create cooler forest microclimates compared to temperatures outside forests.
If you are heading to a farm or the local lot this weekend to pick out your perfect Christmas tree, Timothy Waller, an evergreen researcher, has some advice for you. Waller, an agricultural agent with Rutgers Cooperative Extension of Cumberland County, has been working on Christmas tree disease management and variety demonstrations as part of his ornamental research efforts.
