Abstract:
Compared to accidental adoptions, where offspring is separated from their biological parents during breeding time and gets fostered by foreign adults, strategic adoptions are initiated by the adopted offspring, its biological parents or the adoptive parents and facilitate breeding time because of the benefits of big families or spare the adults breeding time. Accidental adoptions often occur in inexperienced r-strategists with low quality of identification, whereas in small groups living K-strategists, which can practice their breeding quality by additional upbringing, often perform strategic adoptions. The foster mother transmits several behaviour patterns to the offspring like foraging, prevention of predators and care quality. Adopted offspring often has a higher stress resistance. In interspecific adoptions, in which compatible care is essential for the survival of the adopted offspring, sexual mismatch and transfer of vocals or migration routes can occur. This has an impact on all involved animals and can shift ecological niches because of changes in behavioral patterns. In this paper a management approach is created, in which by an initiated interspecific adoption (cross-fostering) offspring of the endangered European mink Mustela lutreola is fostered by outdoor living American mink Neovison vison. Both species are similar in breeding behavior and living, but the American mink is highly competitive. There is the long-term objective for offspring of the European mink to learn to live in aquatic habitats this species does not settle up to now, to assert themselves against disturbances and predators and to travel aside the banks for better genetical linkage.
