Description:Policy to address human-wildlife conflict is often controversia
 l and developing policy to mitigate these conflicts is increasingly import
 ant and often driven by both societal and biological factors.  Yet the in
 teraction between societal and biological drivers and the relative contrib
 ution of these to environmental policy remains understudied. Understanding
  these interactions requires both investigation of the latent biological p
 rocesses that give rise to the policy issue and also the societal percepti
 ons of these biological processes.  I investigate these interactions usin
 g a globally important invasive species - Sus scrofa the wild pig.  To el
 ucidate biological processes important for invasive species\, in order to 
 better understand policy opportunities and consequences\, I investigated h
 ypothesis of ecological processes important for short-term population dyna
 mics that contribute to invasive species population growth.  I also inves
 tigated ecological drivers of pathogen prevalence for a single-host and mu
 lti-host pathogen in wild pigs.\n\nWith regard to drivers of population gr
 owth I found consistent differences in the way vital rates and age structu
 re in invasive and native populations contribute to short-term population 
 growth. Contrary to the demographic buffering hypothesis\, vital rates tha
 t had the largest influence on population growth also had the greatest var
 iability. Invasive population’s demonstrated trade-offs between juvenile
  age structure and vital rates indicating demographic buffering may be an 
 important contributor to invasive species population dynamics.\n\nPathogen
  prevalence was associated with environmental gradients effecting host sur
 vival and by changes in mammal host species richness.  A single-host path
 ogen was most sensitive to changes in both environmental conditions and sp
 ecies richness relative to a multi-host pathogen.  I found support for di
 lution effects but did not find support for amplification effects when con
 trolling for environmental factors\, host density and observation error. 4
