  Major Research Achievements

  1. A simulation model investigating joint evolution of seed traits along environmental gradients (New Phyt. 2013, 197: 655-667)

  2. A novel approach for conservation of endangered plant species in which ex situ collections maintained in natural or semi-natural environment called quasi in situ are a part of a complementary ex situ – in situ conservation strategy. The detailed guidelines are proposed for representative sampling of the populations, collection maintenance and utilization for in situ actions. The proposed approach is the first that explicitly takes into account ecologically significant (i.e. adaptive) variation of plants in both ex situ and in situ conservation actions (Biod. & Cons. 2010, 19: 2441-2454, 3157-3169).

  3. A novel approach for testing environmental effects on plant relocation success (J. Appl. Ecology 2011, 48: 265-273).

  4. First comparative study of direct test of local adaptation, crossbreeding and FST-QST test (New Phyt. 2011, 192: 237-248)

  5. A new comparative approach that uses both species and populations to reveal correlated patterns of variation in plants. Similar responses to increasing aridity were found in both species, indicating that a specific adaptive complex of traits have evolved in both species in response to the specific array of environments (Evol. Ecol. 2007, 21: 381-393).

  6. A comparative study of genetic subdivision using molecular markers (RAPD and allozymes) (FST) and quantitative traits (QST) at two special scales (between regions and between populations within regions). The subdivision estimates did not differ at the population scale, i.e. within regions, but differed at the regional scale, for which local adaptation has been previously shown. The applied methodology is new and implies that comparison of the level of subdivision in quantitative traits and molecular markers is indicative of adaptive population differentiation only when sampling is done at the appropriate scale (Heredity 2005, 95: 466-475).

  7. A simulation model, which combines within-patch (population) demographic processes and a simplified maternally inherited single-locus, two-allele genetic makeup of the populations connected through predefined migration rate. (Cons. Biol. 2005, 19: 357-367; J. Ecol. 2005, 93: 1029-1040).

  8. Test of the importance of micro-environmental topographic parameters as predictors of genetic variation using three classes of molecular markers and two classes of phenotypic traits analyzed by canonical ordination. For the first time effect of microscale natural selection on population genetic structure was proved to be apparent resulting from similarity between the patterns of environmental heterogeneity and seed flow (Amer. Nat. 2004, 163: 312-327).

  9. Complex study of signatures of natural selection in wild barley, Hordeum spontaneum using a hierarchical sampling design and innovative analysis of population genetic structure. (Biol. J. Linn. Soc. 2001, 74: 289-303; 2002, 75: 301-312, 75: 313-318, 77: 479-490; Oecol. ­2002, 133: 131-138; Evol. 2002, 56: 1403-1415; J. Her. 2003, 94: 341-351; Isr. J. Pl. Sci. 2004, 52: 223-234).

  10. Mechanism of regulation of reproductive success in a response to stress in barley and oat plants involving offspring quantity/quality (J. Evol. Biol. 2004, 17: 1121-1131; BJLS 2009, 97: 581-593).

  11. Demonstration of importance of the soil seed bank in population demography of an annual plant in relation to aridity (desert vs. Mediterranean) and species' distribution (periphery vs. core). This study highlights the importance of life history adaptations that may evolve under specific selective forces in different parts of a species' range, which, in certain circumstances, may be critical for persistence of a species (Bas. Appl. Ecol. 2004, 5: 53-64; Isr. J. Pl. Sc. 2009, 57: 79-90; PPEE 2012, 14: 335-340).
