Genetic identification of kin in Micronesian kingfishers

Article Abstract:

DNA profiles proved useful in examining potential genetic relationships among 29 Micronesian kingfishers which founded a new captive population. Using these results, appropriate captive breeding methods can be developed and implemented and may lead to the eventual return of the species to the wild. A close relationship was found among three pairs, but first-order relatedness (0.5) could not be conclusively assigned to these founders since similarity values among them all fell within the range of values of non-first-order relationships.

Ancestral inbreeding only minimally affects inbreeding depression in mammalian populations

Article Abstract:

Two different regression models were used to confirm the presence of purging effects in 25 captive mammalian population and to investigate the mechanism of inbreeding depression. Neonatal survival, survival from neonate to weaning, and litter size were investigated. Majority of the species observed showed that inbreeding depression declined in neonatal survival among descendants of inbred animals. A highly significant trend of purging was observed on neonatal survival.

Effects of inbreeding on skeletal development of Rattus villosissimus

Article Abstract:

Generations of inbreeding result in changes in skull shape and enhanced fluctuating asymmetry in skeletal characters in Rattus villosissimus, a species of Australian native rats. When generation number is controlled, inbreeding results in decreased skull dimensions. With controlled inbreeding level, skull sizes increase through generations. Fluctuating asymmetry is prevalent in highly inbred rats of later generations.
