A population’s neutral genetic variation is a composite of its size, degree of isolation and demographic history. Bottlenecks and founder events increase genetic drift, leading to the loss of genetic variation and increased genetic differentiation among populations. Gene flow has the opposite effects. Thus, gene flow can override the genetic patterns caused by founder events. Using 37 microsatellite loci, we investigated the effects of serial bottlenecks on genetic variation and differentiation… 
Population genomics of the Alpine ibex (Capra ibex)
This thesis examined if signals of selection are present in the bottlenecked and reintroduced populations of the Alpine ibex (Capra ibex). By utilizing single nucleotide polymorphism (SNP) data, I
Temporal Variation in the Genetic Composition of an Endangered Marsupial Reflects Reintroduction History
TLDR
It is shown that interbreeding between individuals from different source populations lowered the genetic relatedness among the offspring, but this was short-lived, and the importance of sourcing founders from multiple locations in conservation breeding programs to avoid inbreeding and maximize allelic diversity is highlighted.
High genetic diversity in the remnant island population of hihi and the genetic consequences of re‐introduction
TLDR
Interestingly, this species has very high levels of extra‐pair paternity which may reduce reproductive variance by allowing social and floater males to reproduce a life history trait that together with a large remnant population size may help maintain higher levels of genetic diversity than expected.
Genetics of a reintroduced swift fox population highlights the need for integrated conservation between neighbouring countries
The genetic consequences of reintroductions are rarely considered after releases cease, but long‐term viability depends on linked demography and genetic health. Reintroductions of swift foxes Vulpes
The impact of translocations on neutral and functional genetic diversity within and among populations of the Seychelles warbler
TLDR
Comparing the impact of translocating different numbers of founders on both microsatellite and major histocompatibility complex diversity over a 23‐year period in the Seychelles warbler provides important insights into how to optimize the use of translocation as a conservation tool.
Molecular Analyses Reveal Unexpected Genetic Structure in Iberian Ibex Populations
TLDR
The genetic pattern identified in this study could be the result of strong genetic drift due to the severe genetic bottlenecks in the studied populations, caused in turn by the progressive destruction of natural habitat, disease epidemics and/or uncontrolled hunting.
Statistical inference on evolutionary processes in Alpine ibex (Capra ibex): mutation, migration and selection
TLDR
The fundamental processes of evolution – mutation, recombination, selection, gene flow and genetic drift – are reviewed, and an overview of Bayesian inference in statistical population genetics is given and a particular focus is devoted to approximate Bayesian computation (ABC) in chapter 2.
Absence of founder effect and evidence for adaptive divergence in a recently introduced insular population of white‐tailed deer (Odocoileus virginianus)
TLDR
A weak, albeit highly significant, genetic differentiation between the Anticosti Island population and its source population is revealed, which supports the absence of a strong founder effect due to the large number of founders followed by rapid population growth.
Comparison of historical bottleneck effects and genetic consequences of re‐introduction in a critically endangered island passerine
TLDR
It is concluded that severe historical bottlenecks can leave a large footprint in terms of sheer quantity of genetic diversity lost, however, severely depleted genetic diversity does not render a species immune to further genetic erosion upon re‐introduction.

History vs. current demography: explaining the genetic population structure of the common frog (Rana temporaria)
TLDR
The observed reductions in genetic variability and increased degree of population differentiation towards the north are in line with theoretical and empirical treatments suggesting that effective population sizes decline towards the periphery of a species’ range.
No evidence for loss of genetic variation following sequential translocations in extant populations of a genetically depauperate species
TLDR
The results suggest that subjecting genetically depauperate endangered species to sequential translocations could be used to rapidly establish new populations without further eroding genetic variation.

Microsatellite DNA and recent statistical methods in wildlife conservation management: applications in Alpine ibex [Capra ibex (ibex)]
TLDR
It is shown that genetic variability in ibex populations (HE ≈ 0.13) is among the lowest reported from microsatellites in mammal species, and that the Alpi Marittime–Mercantour population has suffered from a severe genetic bottleneck associated with its reintroduction.
Cumulative effects of founding events during colonisation on genetic diversity and differentiation in an island and stepping‐stone model
TLDR
The cumulative effect of founding events, resulting most often in a transient increase in genetic differentiation and a gradual loss of within‐population heterozygosity, also depends on the age‐structure that is established during colonisation.
Population genetic structure and the effect of founder events on the genetic variability of moose, Alces alces, in Canada
TLDR
Comparisons of allele frequencies for moose from 11 regions of the country suggested that there are at least seven genetically distinct populations in North America, namely Alberta, eastern Ontario, New Brunswick, Cape Breton, Labrador, western Newfoundland, and the Avalon Peninsula of Newfoundland.
Age‐dependent genetic effects on a secondary sexual trait in male Alpine ibex, Capra ibex
TLDR
The results suggest that the horns of ibex males are an honest signal of genetic quality, as well as investigating HFCs for horn growth, body mass and faecal counts of nematode eggs in wild Alpine ibex.
Immigration and the ephemerality of a natural population bottleneck: evidence from molecular markers
TLDR
Results show that immigration at levels that are hard to measure in most field studies can lead to qualitatively very different genetic outcomes from those expected from mutations only, and suggest that future theoretical and empirical work on bottlenecks and metapopulations should address the impact of immigration.
Genetic roots of the red deer (Cervus elaphus) population in Eastern Switzerland.
TLDR
F(ST) values, assignment tests, correspondence analysis, and fuzzy clustering clearly pointed to Liechtenstein as the most probable source population for the red deer in eastern Switzerland, and high gene diversity in all examined populations revealed.
