Deciphering genetic mate choice: Not so simple in group‐housed conservation breeding programs

摘要: Incorporating mate choice into conservation breeding programs can improve reproduction and the retention of natural behaviors. However, different types genetic-based have varied consequences for genetic diversity management. As a result, it is important to examine mechanisms in captivity assess its costs benefits. Most research this area has focused on experimental pairing trials; however, resource-intensive approach not always feasible captive settings interfere with other management constraints. We used generalized linear mixed models permutation approaches investigate overall success group-housed Tasmanian devils at three nonmutually exclusive hypotheses: (a) advantage heterozygous individuals, (b) dissimilar mates, (c) optimum distance, using both 1,948 genome-wide SNPs 12 MHC-linked microsatellites. The managed devil insurance population largest such program Australia known high variance reproductive success. found that nongenetic factors as age were best predictors competitive scenario, younger females older males being more successful. no evidence under hypotheses tested. Mate varies among species across environments, so we advocate studies realistic contexts or wild may apply. Conservation managers must weigh up need wait adequate sample sizes detect risk changes occur during time captivity. Our study shows examining integrating housed realistic, semi-natural group-based be difficult than previously considered.
