As recommended by the NYS Lead Ammunition Working Group, we are investigating the occurrence and distribution of lead (Pb) in scavenging mammals. We found over 43% of trapped fisher (n=589) had detectable levels of Pb compared with 15% of bobcats (n=53). With SUNY-ESF, we are assessing how Pb and anticoagulant rodenticides impact female reproductive potential and population health.
