DESCRIPTION:Conservation science has many challenges. Human pr
 essures are widespread\, come in multiple forms\, 
 yet individual pressures rarely occur in isolation
 . The same can be said of natural pressures. How d
 o we separate these and determine what pressures t
 o mitigate? How do we compensate for the time lag 
 between a disturbance and its demographic outcome 
 when other events occur in-between? How do we moni
 tor the impacts of mitigation efforts on a time sc
 ale that allows course corrections before it’s too
  late? Addressing these questions often requires m
 easures collected over large spatial but short tem
 poral scales\, which is in itself a challenge.\n\n
 My lab has pioneered highly accessible noninvasive
  tools to address such challenges. We developed me
 thods to extract DNA\, hormones and toxins from fe
 ces\, located by detection dogs with very low coll
 ection bias. DNA can determine species and individ
 ual identities\, sex as well as what the animal at
 e. This can provide reliable capture-mark-recaptur
 e data free of capture heterogeneity\, geospatial 
 genetic maps to distinguish populations\, includin
 g poaching hotspots\, assess resources selection a
 nd measure dietary overlap associated with intersp
 ecific competition. Endocrine measures of stress\,
  reproductive and nutritional health from these sa
 me samples can help tie disturbance events to thei
 r eventual demographic outcomes. Impacts of toxin 
 exposure can simultaneously be measured from these
  samples.\n\nI will attempt to illustrate the valu
 e of this approach through case studies conducted 
 by my lab on a diverse array of species.  I will t
 hen open the floor to discuss applications to your
  own work.
