Zusammenfassung: | The geographic range of Canada lynx (Lynx canadensis) extends south from Canada into the United States where they are federally protected as a threatened species. Although inadequate protection of habitat on federal lands was the primary reason for listing, the status of lynx in the lower 48 states is not well understood. Thus, we initiated a telemetry study to assess the status of a lynx population in northern Maine, USA. In this manuscript, we present findings on a source of mortality not previously documented. Between 1999 and 2011, we captured 187 lynx, equipped 85 with radio-collars, and investigated mortalities when they occurred. Predation was the leading source of mortality and accounted for ≥18 of 65 mortalities, 14 of which were attributed to fishers (Martes pennanti). Although fisher predation did not appear to restrict population growth during this study, we recommend that lynx and fishers be monitored where the species coexist to better inform management decisions. |
