OAKFLOW - Intra- and interspecific gene flow in oaks as mechanisms promoting diversity and adaptive potential

Contract nr: QLK5-CT-1999-30960
Project type: RS (Research and Technological Development Project)
Starting date: 01-10-2000
Duration: 48 months
Total cost: 4,292,004 EUR
EC Contribution: 2,081,995 EUR
Scientific Officer: Ignacio SEOANE
Research topic: 5.3.1. Multifunctional management of forests

Abstract:
The project aims at estimating the amount of intra- and interspecific (hybridisation) gene flow in European oaks (Q. petraea and Q. robur mainly, but also other Mediterranean white oaks) by using genetic fingerprints and applying parentage analysis. Natural gene flow due to pollen and seed dispersal, and artificial flow due to manmade seed transfer will be investigated. The consequences of gene flow at the genetic but also ecological level will be addressed. Genomic regions affected by hybridisation will be identified and fitness-related traits will be compared between hybrids and the parental species. These comparisons will be conducted on juvenile and adult material, and natural flow on management rules will be addressed by considering different real cases in strong cooperation with end-users associated to the project.

Objectives:
1. Trace and quantify gene flow (pollen arid seed dispersal) and hybridisation in oaks. Effective natural pollen and seed movements will be detected in 12 mixed oak stands distributed throughout Europe, based on parentage analysis.
2. Evaluate genetic and ecological consequences of gene flow and hybridisation. The balance between 'beneficial' and 'detrimental' effects of natural and artificial gene flow will be investigated and the fitness of hybrids compared with the parental species.
3. Provide guidelines and recommendations for the management of oak stands for various purposes. Impacts of gene flow in silviculture and forest management will be evaluated in different cases (seed and conservation stands, natural regeneration, even and uneven ages stands).
