“…In captivity, sufficient numbers of pups are also produced to maintain an adequate population size. However, it is critically important for the long-term captive propagation of this species, to carefully regulate breeding partners and maintain a population size that will effectively maximize and maintain current levels of genetic diversity (Frantzen et al, 2001). In order to achieve this and to avoid inbreeding depression, current strategies involve the regular translocation of live animals.…”

Numerous strategies have been undertaken to preserve the species, including re-introduction, community awareness and education (Gusset et al, 2008), and captive breeding programs (Frantzen et al, 2001), but still their numbers are in decline . African wild dogs have large home ranges from 1500 to 2000 km 2 and low population densities (Woodroffe and Ginsberg, 1997;, making them relatively vulnerable to habitat fragmentation and to contact with humans or human activities .…”

a b s t r a c tThe African wild dog (Lycaon pictus) is an endangered exotic canid with less than 5500 animals remaining in the wild. Despite numerous strategies to conserve this species, numbers of free-living animals are in decline. It is a highly social species with a complex pack structure: separate male and female dominant hierarchies with, typically, participation of subdominant adults in the rearing of the dominant breeding pairs' pups. Basic reproductive knowledge is largely missing in this species, with only limited information available on the profile of reproductive hormones, based on non-invasive endocrine monitoring. The dominant or alpha male and female are reproductively active and the subdominants are generally reproductively suppressed. However, the occasional production of litters by subdominant females and evidence of multiple paternity within litters suggests that fertility of subordinates is not completely inhibited. In this respect, there are still considerable gaps in our knowledge about the mechanisms governing reproduction and reproductive suppression in African wild dogs, particularly the influence of dominance and pack structure on both male and female fertility. Given concerns over the long-term survival of this species, further research in this area is essential to provide valuable information for their captive breeding and conservation. Reproductive information can also be applied to the development of Assisted Reproductive Techniques for this species; the utility of which in African wild dog conservation is also discussed.

“…These effects clearly militate against successful reintroductions (Frankham 2005). For example, reintroductions of red wolves ( Canis rufus ) and African wild dogs ( Lycaon pictus ) demonstrated that individuals born in captivity are unable to capture their own prey adequately, or avoid their natural predators, or escape accidental death by road vehicles and other causes (Moore and Smith 1990; Frantzen et al. 2001).…”

The European mink (Mustela lutreola) is a small mammal, which belongs to the Mustelidae family (Carnivora). Earlier, the range of distribution of this species encompassed much of the European continent. During the 20th century, the numbers of European mink declined and the range of its distribution became reduced to three fragmented populations; today this species faces extinction. The urgent necessity for effective conservation efforts to protect the European mink is accepted by the governmental organizations as well as scientific communities of most European countries. In this paper, the reasons for the disappearance of European mink are reviewed and results of past conservation efforts based on captive breeding and reintroduction programmes are critically evaluated in the broad context of modern concepts of conservation genetics and reproductive biology. The data recently obtained on the reproduction and pre-implantation development of European mink and the prospects of incorporation of modern reproductive technologies into the conservation programme of this species are discussed.

“…Attempts to release captive‐bred wild dogs often failed as a result of their lacking survival (particularly hunting and anti‐predatory) skills in the wild (Frantzen, Ferguson & De Villiers, 2001), yet it appears that wild dogs bred or raised in captivity can be used for release, where necessary (Table 1). This however is apparently only possible when they are bonded with wild‐caught animals in a boma first, as all (five) but one (Madikwe Game Reserve in 1998) translocations involving solely animals bred or raised in captivity failed (independent of the release protocol; Table 1), and all attempts at pre‐ and post‐release hunting training met with limited success (Etosha National Park in 1990, Klaserie Game Reserve in 1991 and Tsavo West National Park in 1997).…”

Divided we fail: the importance of social integration for the re‐introduction of endangered African wild dogs (Lycaon pictus)

2006

In South Africa, a plan was launched to manage separate sub-populations of endangered African wild dogs Lycaon pictus in several small, geographically isolated conservation areas as a single meta-population. This intensive management approach involves the re-introduction of wild dogs into suitable conservation areas and periodic translocations among them. Here, we sought to evaluate the relevance of taking the formation of new reproductive units into consideration in promoting such translocation attempts. For this purpose, we analysed the behavioural process of integrating translocated wild dogs into new packs in pre-release holding facilities in Hluhluwe-iMfolozi Park, one of the meta-population conservation areas. In addition, we reviewed findings from other wild dog translocation attempts in regard to the outcome of using variously composed groups and captive-bred animals for the artificial creation of new packs for translocation purposes. We show the importance of social integration before release for wild dog re-introductions and translocations to be successful. We also present a set of proximate factors, including management manipulation of social relationships, which promote pack formation in pre-release holding facilities. This demonstrably enhances the efficiency of costly wild dog re-introductions and translocations, thereby illustrating the implications of sociality for endangered species recovery.
