History of Managed Care

Europe

  • Early records
    • 1861: 1st aye-aye, an adult female, on display at the London Zoo (Bartlett 1862; Winn 1989)
    • 1862-1927: 19 individuals were held in 8 zoos

    • 1932-1982: no individuals housed outside of Madagascar (Feistner and Carroll 1993)

Notable events

  • First birth in managed care April 1992, Duke Primate Center (DPC) (Carroll and Haring 1994; Feistner and Ashbourne 1994; Feistner and Carroll 1993)
    • Wild caught female unexpectedly gave birth to a son, conceived in the wild (Carroll and Haring 1994)

Breeding in Managed Care

  • Limited opportunities for managed individuals to breed prior to 1992
    • Few facilities housed male-female pairs (Simons 1995)
  • Recent breeding efforts begun by Duke Lemur Center
    • Designed to guard against extinction (Feistner and Ashbourne 1994)
    • All aye-aye in North American zoological facilities are decended from this managed breeding program (Gibson 2012)

Breeding in Managed Care Guards Against Extinction

an Aye-Aye baby being cared for

Prior to 1992, there were few opportunities for individuals in managed care to breed.

Efforts to propagate aye-aye by Duke Primate Center (now Duke Lemur Center) have resulted in a healthy North American managed care population consisting of over 30 individuals, all of which are descendants of 6 wild caught founders. Efforts by Duke and a select group of AZA institutions help guard against extinction.
