| introduced pathogens follow the invasion front of a spreading alien host. | 1. when an invasive species first colonizes an area, there is an interval before any host-specific natural enemies arrive at the new location. population densities of newly invading species are low, and the spatial and temporal interactions between spreading invasive species and specific natural enemies that follow are poorly understood. 2. we measured infection rates of two introduced host-specific pathogens, the entomophthoralean fungus entomophaga maimaiga and the baculovirus lymantria dispar ... | 2011 | 21644978 |
| preoutbreak dynamics of a recently established invasive herbivore: roles of natural enemies and habitat structure in stage-specific performance of gypsy moth (lepidoptera: lymantriidae) populations in northeastern wisconsin. | a major challenge to addressing biological invasions is that the need for emergency responses often precludes opportunities to analyze the dynamics between initial establishment and population eruption. thus, a broader understanding of underlying processes and management opportunities is often lacking. we examined the effects of habitat structure and natural enemies on recently established preeruptive gypsy moth, lymantria dispar l., populations over 4 yr in northeastern wisconsin. forty-five si ... | 2008 | 19036196 |
