    Notes: Abstract Adult-infant food-sharing behavior is a major component of the infant care strategies of callitrichids (marmosets and tamarins). It is particularly well-developed in cotton-top tamarins (Saguinus Oedipus) and lion tamarins (Leontopithecus spp), which show frequent adult-initiated food offering, as well as sharing of food in response to begging by infants. This report documents a case of cross-generic food sharing, in which a male golden-headed lion tamarin (Leontopithecus chrysomelas) shared food with an infant cotton-top tamarin. The lion tamarin provided more food to the infant than its mother did. This emphasizes the importance of this behavior in the reproductive strategies of the communally-rearing Callitrichidae and raises questions about mechanisms that underly it.

    Notes: Abstract Despite early menageries being the source of much useful biological information on anatomy and taxonomy, it is only more recently that the potential for research in zoos has been recongnized. Collections of captive animals are unique and irreplaceable resources for conservation; but without research in zoological parks, progress in conservation science would diminish. There is a flow of information from zoo researchers to field scientists that assists in providing new insights into species biology. Reciprocally, data collected in the field enhance efforts in captive breeding. This paper summarizes the new research initiatives undertaken in zoos, e.g., in the fields of reproductive and genetic technologies, and highlights their significance for conservation and management of threatened species. It is evident that zoo research has a vital role in linking in situ and ex situ conservation. This role needs to be expanded and developed to meet the challenge posed by expanding human and declining wildlife populations and ecosystems.

    ISSN: 1572-9710
    Keywords: Daubentonia ; aye-aye ; captive breeding ; Madagascar

    Topics: Biology
    Notes: In August 1992 an aye-aye Daubentonia madagascariensis (Primates) was bred in captivity for the first time. This species is the only living representative of a monotypic family and is endangered in its native Madagascar. A brief history of the captive breeding effort and a summary of the conservation problems facing the fauna, flora, and people of Madagascar is given. The role that a captive breeding programme for aye-ayes can fulfil as an aid to preserving biodiversity is discussed.
