Abstract:

Researches in recent decades have revealed a clear change in global climate, which cannot remain without effects on forest ecosystems. Although there is a high degree of uncertainty regarding these influences it is still widely accepted that mountain ecosystems will be the most vulnerable to climate change. The real potential for adaptation depends upon the existence of a wide genetic diversity in trees populations, upon the adaptive genetic variation - respectively. Genetic diversity offers the guarantee that forest species can survive, can adapt and evolve under the influence of changing environmental conditions. Therefore, the project goal is to evaluate the adaptive genetic potential of the Norway spruce, Silver fir and Scots pine, the most economically and ecologically important forest species in Romania, in the context of climate change. Project will provide scientific results and technical recommendations for optimizing the forest management in view of the sustainable utilization of forest ecosystems.

NATURAL HYBRIDIZATION WITHIN QUERCUS SPECIES COMPLEX IN ROMANIA Call name: Projects for Young Research Teams - TE-2010 call

Abstract:

N THE LAST YEARS THE STUDY OF NATURAL HYBRIDIZATION HAS BECOME A CENTRAL THEME IN EVOLUTIONARY BIOLOGY AND ECOLOGY. THE IMPORTANCE OF THIS PHENOMENON IS GIVEN BY ITS EVOLUTIONARY CONSEQUENCES (E.G. FORMATION OF NEW SPECIES, ORIGIN AND TRANSFER OF ADAPTATIONS). OAKS (QUERCUS SPP.) ARE LONG STANDING MODEL ORGANISMS FOR THE STUDY OF HYBRIDIZATION. THE AIM OF THIS STUDY IS TO BRING NEW INSIGHTS INTO OCCURRENCE AND DYNAMICS OF NATURAL HYBRIDIZATION WITHIN THE QUERCUS SPECIES COMPLEX FROM ROMANIA. TO INVESTIGATE HYBRIDIZATION, PURE POPULATIONS AS WELL AS A ZONE OF SECONDARY CONTACT BETWEEN OAK SPECIES WILL BE SAMPLED. SIMPLE SEQUENCE REPEATS (SSRS) FROM OUTSIDE AND INSIDE OF THE TRANSCRIBED REGIONS OF THE GENOME (EXPRESSED SEQUENCE TAGS) ARE TO BE USED FOR QUANTIFYING THE GENETIC STRUCTURES. TO IDENTIFY FIRST-GENERATION HYBRIDS AND INTROGRESSED FORMS, ASSIGNMENT TESTS BASED ON BAYESIAN ADMIXTURE ANALYSIS WILL BE USED. THE STUDY WILL CONSIDER THE INTERSPECIFIC GENE FLOW IN THE ADULT AND ACORN GENERATION AS WELL. THE CONTEMPORARY GENE FLOW WILL BE ESTIMATED BY USING PATERNITY ANALYSES. MOREOVER, OBSERVATION OF THE FLOWERING PHENOLOGY IN THE SECONDARY CONTACT ZONE WILL CONTRIBUTE TO A BETTER UNDERSTANDING OF THE DETECTED CROSSING PATTERNS. THE DATA OBTAINED FROM THIS MULTIDISCIPLINARY BASIC RESEARCH (FOREST GENETICS, EVOLUTIONARY BIOLOGY AND FOREST ECOLOGY) WILL BE VERY USEFUL FOR THE CONSERVATION AND SUSTAINABLE MANAGEMENT OF THE OAK GENETIC RESOURCES FROM ROMANIA.
