Genetic resources, biodiversity & breeding

Genetic variation is the fundamental level of biodiversity, provides the basis for evolutionary change and is crucial for maintaining adaptability and responding to human induced selection.

Genetic resources, biodiversity & breeding

The present increased habitat modification and climate change, urge to study the effects of past and present evolutionary changes on intraspecific genetic diversity to decipher the evolutionary consequences of various environmental changes. Examining contemporary and previous genetic structure of Fennoscandia reindeer provides a unique opportunity to assess the effects of historical processes including human interference, and the impact of climate on gene flow and genetic diversity.

Nordic responsibility
The Nordic countries have a special responsibility to ensure long-term survival of the domestic and the remaining native wild reindeer herds. Both are exposed to a combined natural and human induced selection influencing phenotypic characters. Knowledge of how phenotypic characters respond to various management and selection regimes are crucial for predicting their response to future environmental changes. Indeed, this is critical for assessing the breeding scheme practised in reindeer husbandry and the feasibility of applying new selection techniques emerging.

Objectives - To identify drivers of genetic diversification and evolutionary changes of reindeer herds for sustainable and flexible management strategies in a changing Arctic by: 

  • unravelling the origin of different reindeer lineages in Scandinavia and their significance for the early domestication process
  • estimating how rapid fitness-related characters of reindeer will respond to drivers affecting changes in the environment
  • evaluating the possibilities and feasibility to improve the production efficiency in reindeer husbandry by implementing selective breeding schemes
