“…The percentage of polymorphic products in all the populations analyzed was rather equal and far higher than in other studies on peripheral or isolated populations of other plant species (Smulders et al, 2008;Grossi et al, 2011;Sochor et al, 2013). Although the expected heterozygosity (H e ) ranged from 0.143 (population B) to 0.187 (population M) and these values were quite similar to the results obtained in other studies using dominant markers (Smulders, 2008;Sochor et al, 2013), they were still lower in comparison to codominant markers (Kikuchi et al, 2011;Lee et al, 2011;Sochor et al, 2013).…”

The main aim of the study was to increase the knowledge on the ecology and biology of the boreal relict Salix lapponum L., an endangered plant in Poland, in order to create an effective protection program. An important aspect was to determine the within-and among-population genetic diversity of the studied species in order to evaluate whether the basic stages of the generative reproduction cycle in the populations were correct. The results confirmed that S. lapponum pollen viability and germinability, for both fresh and stored pollen, were high and so were the seed germination ability and dynamics. All individuals were of sexual origin and the expected heterozygosity was moderate. In spite of this, young individuals were observed in only 1 out of 5 studied populations and it was the most numerous one. Although the genetic diversity among the populations was not very high (Φ PT = 0.12), it accumulated in a quite short period of time, probably during the second part of the 20th century, as a consequence of habitat fragmentation. A lack of gene flow, either by pollen or seeds, may lead to further differentiation of the populations and extinction of the smallest ones. For this reason, preventive measures should be undertaken in order to enlarge the existing populations and to reconstruct S. lapponum populations in selected sites where environmental conditions are the most similar to those preferred by this species.

Summary: Geographical range and spatial structure of genetic lineages in Sophora linearifolia (Fabaceae), an endemic shrub of Central Argentina. A large number of endemic species occur in the Sierras of Córdoba and San Luis. A significant group of them shows a disjunct geographic distribution between these two mountain regions. Until the present study, there were none genetic studies that allow us to infer historical processes underlying this geographical pattern. For this purpose, we characterize the distribution area and phylogeographic patterns of Sophora linearifolia, across its geographic range which includes Sierras Chicas (SC) and Cumbres de Gaspar (CG) in Córdoba and in the southwestern area of Sierras of San Luis (SL). We compared the current with the predicted species area of distribution using ecological niche modelling analysis. We also analyzed genetic variability and spatial structure of the DNA chloroplast marker trnH-psbA, and reconstructed the genealogical relationships among the retrieved haplotypes. Current and the predicted distribution agreed in showing a climatic/topographic disjunction between Sierras of Cordoba and San Luis hills, although the current distribution presents a disjunction between SC and CG in Córdoba, not shown in the potential distribution map. We obtained eight haplotypes with restricted distribution and low levels of genetic differentiation that were grouped into four phylogroups: SC, CG and two in SL. Our results indicate that S. linearifolia presents low dispersal ability and it would have recently diversified, suggesting a neoendemic taxon.Key words: Chloroplastidial DNA, biogeography, disjunct, distribution, ecological niche modelling, phylogeography, neoendemic, Sierras Pampeanas.Resumen: Las sierras de Córdoba y San Luis albergan una gran riqueza de especies endémicas. Un grupo importante de ellas muestra una distribución disyunta entre ambas serranías. Hasta la actualidad no existían estudios genéticos que permitieran inferir procesos históricos asociados a este patrón. Con este propósito caracterizamos el área de distribución y el patrón filogeográfico de Sophora linearifolia, abarcando todo su rango geográfico que incluye las Sierras Chicas (SC) y las Cumbres de Gaspar (CG) en Córdoba y el suroeste de las Sierras de San Luis (SL). Contrastamos la distribución actual con la distribución predicha a partir del modelado del nicho ecológico. Analizamos el nivel de variabilidad genética, la estructuración espacial del marcador de ADN plastidial trnH-psbA y reconstruimos las relaciones genealógicas entre los haplotipos. La distribución actual y la predicha mostraron una disyunción entre Córdoba y San Luis, pero la distribución actual presentó una disyunción entre SC y CG que no fue modelada en la distribución potencial. Se obtuvieron 8 haplotipos de distribución restringida con bajos niveles de diferenciación genética agrupados en 4 filogrupos: SC, CG y dos en SL. Nuestros resultados indican que S. linearifolia presentaría baja capacidad de dispersión y que se habría d...
