Abstract Interpretations of current diversity patterns based on the contraction/expansion model forced by climatic oscillations during last two million years are commonplace in phylogeographic literature. Of wealth scientific studies accumulated past decades Europe, ones we understand best those mostly from higher latitudes, probably because were simplified to a great extent major losses glacial periods. In Southern European regions (or general, places where ice effects less severe)...
Abstract Nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) sequences from artificial hybrids and backcrosses between Armeria villosa ssp. longiaristata A. colorata were studied to assess the possible effects of concerted evolution in natural hybrids. F 1 show expected pattern additive polymorphisms for five six variable sites as estimated direct sequences. However, homogenization polymorphism is already observed 2 , biased towards except one site. In backcrosses, an tendency...
The fundamental value of universal nomenclatural systems in biology is that they enable unambiguous scientific communication. However, the stability these threatened by recent discussions asking for a fairer nomenclature, raising possibility bulk revision processes "inappropriate" names. It evident such proposals come from very deep feelings, but we show how can irreparably damage foundation biological communication and, turn, sciences depend on it. There are four essential consequences...
• Background and Aims Isolation drift are the main causes for geographic structure of molecular variation. In contrast, one found in a previous survey Armeria (Plumbaginaceae) nuclear ribosomal ITS multicopy regions was species‐independent has been hypothesized to be due extensive gene‐flow biased concerted evolution. Since this inferred from genus‐level phylogenetic analysis, aim study check occurrence such validity proposed model at local scale, southern Spanish massif (Sierra Nevada), as...
Abstract In contrast to northern European areas where large‐scale migrations occurred recolonize territories after glacial periods, species in southern regions survived and diverged without large geographical displacements. As a result of the importance orography much areas, such displacements must have involved populations ascending or descending mountains. The present study provides support for glacial‐induced altitudinal from chloroplast phylogeographic patterns Armeria (Plumbaginaceae)...
Abstract Inferring the evolutionary history of Mediterranean plant lineages from current genetic, distributional and taxonomic patterns is complex because a number palaeoclimatic geological interconnected factors together with landscape heterogeneity human influence. Therefore, choosing spatially simplified systems as study groups suitable approach. An amplified fragment length polymorphism (AFLP) using two restriction enzyme combinations ( Eco RI/ Mse I Kpn I/ I) was carried out to estimate...
Changes in the amount of repetitive DNA (dispersed and tandem repeats) are considered main contributors to genome size variation across plant species absence polyploidy. However, study repeatome dynamism groups showing contrasting genomic features complex evolutionary histories is needed determine whether other processes underlying may have been overlooked. The aim here was elucidate which mechanism best explains evolution Anacyclus (Asteraceae).Using data from Illumina sequencing, we...
Cladistic analyses of the nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) sequences from 55 samples corresponding to 34 taxa in genus Armeria reveal that ITS sequence diversity among and within species utterly conflicts with patterns morphological similarity. Three facts are apparent results here reported: (1) different a single subspecies, A. villosa subsp. longiaristata, appear three five major clades; (2) at least one six subspecies four (3) composition clades shows...
Abstract Aim Phylogeography of fruit trees is challenging due to recurrent exchanges between domesticated and wild populations. Here we tested the eastern refugium hypothesis (ERH) for carob tree, Ceratonia siliqua , which supports its natural domestication origins in Mediterranean a feral origin west. Location basin. Taxon L., Leguminosae . Methods A phylogenetic reconstruction based on two nuclear one plastid sequences was performed estimate divergence time tree sister species, oreothauma...
Abstract Background and Aims Herbaria are powerful sources of data material nowadays that can be used for analyses other than taxonomic purposes. Improved techniques DNA extraction from old herbarium specimens combined with modern relatively cheap genomic tools, allow the reassessment identity important potential consequences on species conservation status. In this study, we a approach applied to type mid-19th century elucidate Armeria arcuata correctly identify living plant (code:...
Abstract Aim The aim of this study was to test hypotheses regarding some the main phylogeographical patterns proposed for European plants, in particular locations glacial refugia, post‐glacial colonization routes, and genetic affinities between southern (alpine) northern (boreal) populations. Location mountains Europe (Alps, Balkans, Carpathians, Central Massif, Pyrenees, Scandinavian chain, Sudetes), central European/southern lowlands. Methods As our model system we used Pulsatilla vernalis...
Abstract Background and Aims Natural hybridisation can lead to diversification adaptive introgression, among other outcomes. However, the mechanistic underpinnings of this process are insufficiently understood. A previous study Iberian endemic diploid genus Phalacrocarpum (Asteraceae, Anthemideae) identified several homoploid events cryptic diversity, but raised questions regarding their evolutionary significance specific genetic groups involved. This aimed clarify history genus. Methods...
Seventy‐four nucleotide sequences from the ITS regions of nuclear ribosomal DNA and 76 trnL ‐ trnF spacer chloroplast were used to address origin tetraploid Cardamine amporitana , conspecifity central Italian northeastern Spanish populations, possible cause for such geographic disjunction. Because complex lineage relationships in sampling included 22 taxa. In results, both data sets are highly congruent supporting a close relationship C. widespread Eurasian amara . Low genetic variability...
Evolutionary consequences of natural hybridization between species may vary so drastically depending on spatial, genetic, and ecological factors that multiple approaches are required to uncover them. To unravel the evolutionary history a controversial hybrid (Narcissus x perezlarae), here we use four approaches: DNA sequences from five regions (four organellar, one nuclear), cytological studies (chromosome counts genome size), crossing experiments, niche modeling. We conclude (1) it actually...
The nuclear genome harbours hundreds to several thousand copies of ribosomal DNA. Despite their essential role in cellular ribogenesis few studies have addressed intrapopulation, interpopulation and interspecific levels rDNA variability wild plants. Some assessed the extent variation at sequence copy-number level with large sampling species. However, comparable on site number plants, extensive hierarchical (individuals, populations, species) are lacking. In exploring possible causes for loci...
