Direct and indirect effects of alien insect herbivores on ecological processes and interactions in forests of eastern North America (2010, background): “, which are keystone species in riparian areas in the Appalachian forests (Orwig et al. 2002; Ellison et al. 2005; Small et al. 2005).”
Does mixing litter of different qualities alter stream microbial diversity and functioning on individual litter species (2009, background): “Current declines in Tsuga canadensis, eastern hemlock, resulting from infestation by an invasive invertebrate pest, Adelges tsugae, woolly adelgid, are altering forest communities along the Appalachian Mountains (Orwig et al. 2002).”
A geographically variable model of hemlock woolly adelgid spread (2007, background): “In eastern North America, HWA has both a spring and summer generation but reproduces only asexually.”
Responses of insect pests, pathogens, and invasive plant species to climate change in the forests of northeastern North America: what can we predict? (2009, background): “Continued infestation threatens to produce a range-wide decline or elimination of this ecologically, culturally, and economically important species (Orwig and Foster 1998; Orwig et al. 2002).”
Density-dependent tree mortality in pinyon-juniper woodlands (2008, positive): “Other studies have found that trees on drier aspects grow less vigorously due to increased moisture stress (Kaufmann and Ryan, 1986), which could also make these trees less resistant to mortality outbreaks (Orwig et al., 2002).”
Vegetation dynamics in declining eastern hemlock stands: 9 years of forest response to hemlock woolly adelgid infestation (2006, background): “It has also been suggested that HWA will lead to a significant reduction in landscape-level diversity and structural complexity (Orwig et al. 2002).”
Anisotropic spread of hemlock woolly adelgid in the eastern United States (2009, neutral): “(McClure et al. 2001; Orwig et al. 2002).”
Role of winter temperature and climate change on the survival and future range expansion of the hemlock woolly adelgid (Adelges tsugae) in eastern North America (2008, background): “The removal of hemlock from the landscape in some areas has already resulted in changes in forest structure and composition (Orwig and Foster 1998; Orwig et al. 2002) as well as ecosystem function (Jenkins et al.”
Avian response to removal of a forest dominant: consequences of hemlock woolly adelgid infestations (2002, methodology): “…it is typically replaced by hardwoods which are dominant across the region; as a result, the forest landscape is expected to become more homogenous (Jenkins et al., 2000; Orwig et al., 2002), which may eventually lead to a decline in the overall species richness of birds as well as other species.”
Modeling biological disturbances in LANDIS: a module description and demonstration using spruce budworm (2004, background): “…quantified many of the local stand characteri e.g., host abundance, age, stand structure, soil m ure, etc.) that determine the relative vulnerability tand to an outbreak should one occur (Batzer, 1969 ulf, 1985; Shore and Safranyik, 1992; Bergeron e 995; Chojnacky et al., 2000; Orwig et al., 2002).”
Ecosystem to regional impacts of introduced pests and pathogens: historical context, questions and issues (2002, background): “Orwig et al. (2002) document the distribution of HWA, its rate of spread and its impact on tree vigour and mortality in southern New England.”
Multi-year ecosystem response to hemlock woolly adelgid infestation in southern New England forests (2008, background): “The region encompasses considerable variation in timing of initial HWA infestation (Orwig et al. 2002), and is characterized by a humid, continental climate with long, cool winters and short, mild summers (Hill et al. 1980).”
