| Summary: | Genetic and genomic tools have provided researchers with the opportunity to address fundamental questions regarding the reintroduction of species into their historical range with greater precision than ever before. Reintroduction has been employed as a conservation method to return locally extinct species to their native range for decades. However, it remains unknown how genetic factors may impact population establishment and persistence at the population and metapopulation level in the short- and long-term. Genetic methods are capable of producing datasets from many individuals, even when only low quality DNA can be collected. These methods offer an avenue to investigate unanswered questions in reintroduction biology, which is vital to provide evidence based management strategies for future projects. The Eurasian lynx (Lynx lynx) and European wildcat (Felis silvestris) are elusive carnivores native to Eurasia and have been the subject of multiple reintroduction attempts into their native range. During the 19th and 20th century, the Eurasian lynx was extirpated from West and Central Europe due to increasing habitat fragmentation and persecution. Similarly, the European wildcat was the subject of human persecution, residing in a few refugia in West and Central Europe. After legal protection in the 1950s, subsequent reintroduction projects of both species began in the 1970s and 1980s and continue to the present. Despite this large focus on species conservation, little attention has been given to the consequences these reintroductions have on the genetic composition of the reintroduced populations and if the populations have a chance of persisting in the long term. These species have not yet benefited from the large range of genetic and genomic techniques currently available to non-model organisms, leaving many fundamental aspects of their reintroduction poorly understood. In my dissertation, I investigate demography, population structure, genetic diversity and inbreeding at the population and metapopulation level ... |
