Sex-biased dispersal in western lowland gorillas (Gorilla gorilla gorilla)
We explored two hypotheses related to potential differences between sexes in dispersal behaviour in western lowland gorillas (Gorilla gorilla gorilla). Direct observations suggest that immature females have more opportunities to move between breeding groups than immature males. The distribution of kin dyadic relationships within and between groups does not, however, support this hypothesis. At larger […]
Founder contribution and pedigree inference in a captive breeding colony of lion-tailed macaques, using mitochondrial DNA and DNA fingerprint analyses
Abstract 10.1002/zoo.1430100408.abs Captive colony genetic management is dependent on knowledge of the colony pedigree. In most zoos, records for colonies held prior to the past decade are incomplete or nonexistent. We have used a nested set of molecular techniques to infer genetic relationships in a colony of 15 lion-tailed macaques after twenty years of unmonitored […]
Duck’s Not Dead: Does Restocking With Captive Bred Individuals Affect the Genetic Integrity of Wild Mallard (Anas platyrhynchos) Population?
The genetic integrity of natural populations can be threatened through large-scale introduction of farmed stocks with different genetic or geographic origin. Huge numbers of farm-reared mallard (Anas platyrhynchos, Anatidae) have been introduced into the wild in many European countries since 1970. Czech breeding facilities currently produce around 200–300,000 ducks annually, exceeding wild numbers by around […]
Genetic differentiation in proboscis monkeys—A reanalysis
Ogata and Seino [Zoo Biol, 2015, 34:76–79] sequenced the mitochondrial D-loop of five proboscis monkeys Nasalis larvatus from Yokahama Zoo, Japan, that were imported from Surabaya Zoo, Indonesia. They compared their sequences with those of 16 proboscis monkeys from Sabah, Malaysia, and on the basis of a haplotype network analysis of 256 base pairs concluded […]
