Hotspots of pest-induced US urban tree death: culprits, impacted tree species, and spatial hotspots

In their latest research Emma J. Hudgins, Frank H. Koch, Mark J. Ambrose, and Brian Leung, discuss the economic implications of pest-induced tree deaths in the US. Urban trees are key to the wellbeing of city dwellers but are at high risk of mortality from insect pests, due to having high rates of exposure to invasive species as enabled by trade, travel, and other human … Continue reading Hotspots of pest-induced US urban tree death: culprits, impacted tree species, and spatial hotspots

How to manage city trees in a changing climate?

Without sufficient water, urban trees are susceptible to other stressors, including insect pests. Associate Editor, Pieter De Frenne (Ghent University, Belgium) explains how Meineke and Frank’s recent paper, Water availability drives urban tree growth responses to herbivory and warming, provides key research into the management of a vital ecosystem service. Cities are hot. Not only to taste the best latte macchiato in the fanciest coffee … Continue reading How to manage city trees in a changing climate?

Warming, insect pests and water stress combine to reduce tree growth in the city

Emily Meineke comments on new research, Water availability drives urban tree growth responses to herbivory and warming  published today in Journal of Applied Ecology. Cities are getting warmer. This is due in part to global climate change. The more important factor for now, though, is the urban heat island effect; local warming in cities caused by sidewalks, asphalt, and reduced tree cover. In short, areas with less … Continue reading Warming, insect pests and water stress combine to reduce tree growth in the city
