Conservation Genetics

ETH-Vorlesungsverzeichnis: 701-1450-00L Conservation Genetics

Frühjahrssemester 2012 (jährlich wiederkehrende Veranstaltung)

Lernziel

Genetic and evolutionary argumentation is an outstanding feature of modern conservation biology. The module equips students with the necessary background knowledge on the benefits of conservation genetics and its applications in practice. The module introduces several main theories of conservation genetics and then shows how they impact on practical work in conservation management. The module aims at a critical discussion of the role and limits of genetics in conservation and also shows where science is lacking behind practice - and vice-versa. Both animals and plants are treated.

Inhalt

Overview
What is conservation genetics; genetic diversity as part of biodiversity; neutral and adaptive genetic diversity; effects of small population size: genetic drift and inbreeding; gene flow and fragmentation/connectivity; in-situ and ex-situ species conservation; hybridization.

Specific topics
(1): What is conservation genetics; why is it important (ecology versus genetics); biodiversity and genetic diversity; genetics as an instrument to investigate processes, extinction vortex; basic introduction to genetic methods.
(2) Small population size and genetic drift/inbreeding; inbreeding depression; methods to estimate inbreeding and inbreeding depression; applications to conservation.
(3) Adapative genetic diversity; neutral versus adaptive genetic variation and their meaning; methods to measure them; genome scans; QTLs, candidate genes; problems and open questions; use and misuse of molecular markers in practice.
(4) Gene flow, migration and dispersal; how to measure them (historical versus current); applications related to fragmentation, connectivity, evaluation and monitoring.
(5) Hybridization and conservation genetics; gene introgression; gene flow across species boundaries; crops and wild relatives.
(6) Two excursions: examples of pratical conservation genetics in the field and critical discussions.
(7) Examination.
