Abstract (from Springer): Exotic plants are common in urban landscapes and are often planted by landscape managers in an effort to reduce herbivory damage and improve landscape aesthetics. However, exotic plants may be less palatable to many native insects and reduce herbivore biomass that may fuel higher trophic levels. Furthermore, a loss of herbivores in exotic ornamental landscapes may reduce top-down control by natural enemies. In this study, we compare herbivory in native and exotic congener ornamental landscapes. We also explore if caterpillar abundance, natural enemy abundance, diversity, community composition, spider biomass, and egg predation differ between the two landscape types. We predicted that herbivory,...
Abstract (from ScienceDirect): Trees are important components of urban landscapes because of the ecosystem services they provide. However, the effects of urbanization, particularly high temperatures, can benefit chronic insect pests and threaten ecosystem services offered by urban trees. Urban forest fragments are an often-overlooked component of the greater urban forest which may help to mitigate the damaging effects of urbanization. Melanaspis tenebricosa (gloomy scale) is a common pest of Acer rubrum(red maple) that becomes more abundant because of the urban heat island effect. We conducted observational and manipulative field experiments to test the hypothesis that trees in urban forest fragments would be cooler...
