Gene Flow between Potato Cultivars under Experimental Field Conditions in Argentina
(Springer, 2014-06)
Wild and cultivated potatoes form a polyploid series with 2n = 2x to 2n = 6x (x = 12). In nature, they are separated by external and/or internal hybridization barriers that, when incomplete, provide opportunities for gene ...
Pollen-mediated gene flow from a commercial potato cultivar to the wild relative S. chacoense bitter under experimental field conditions in argentina
(Wiley Blackwell Publishing, Inc, 2013-12-10)
The common potato, Solanum tuberosum ssp. tuberosum (tbr, 2n = 4x = 48; 4EBN), has many closely related wild tuber-bearing species. Around 28 to 35 of them spontaneously grow in Argentina overlapping, in some areas, with ...
Gene flow between cultivated and wild sunflower Helianthus annuus in Argentina
(Elsevier Science, 2008)
Dynamics of glyphosate resistance in Lolium perenne: pollen-mediated gene flow under field conditions in Argentina
(MDPI, 2018-11)
The genus Lolium has shown a high tendency to evolve resistance to herbicides. Considering the high level of allogamy of L. perenne and the importance of the wind as an agent for pollen dispersion, the aim of this work was ...
Conservation in the southern edge of Tetrao urogallus distribution: Gene flow despite fragmentation in the stronghold of the Cantabrian capercaillie
(Springer, 2017-06)
The Cantabrian capercaillie (Tetrao urogallus cantabricus) is an endangered subspecies of the Western capercaillie, endemic of northern Spain, inhabiting the south-western limit of the species range. Assessing genetic ...
Gene flow in Argentinian sunflowers as revealed by genotyping‐by‐sequencing data
(2018-02)
Gene flow can have several different applied consequences, ranging from extinction to the escape of transgenes to the evolution of weedy or invasive lineages. Here, we describe patterns of hybridization and gene flow ...
Species delimitation with abc and other coalescent-based methods: A test of accuracy with simulations and an empirical example with lizards of the liolaemus darwinii complex (Squamata: Liolaemidae)
(Wiley Blackwell Publishing, Inc, 2012-09)
Species delimitation is a major research focus in evolutionary biology because accurate species boundaries are a prerequisite for the study of speciation. New species delimitation methods (SDMs) can accommodate nonmonophyletic ...
Integrating Different Biological Evidence Around Some Microevolutionary Processes: Bottlenecks and Asian-American Arctic Gene Flow in the New World Settlement
(BioMed Central, 2011-05)
Excepting some specific efforts, most of the mainstream debate around the Americas' settlement has been directed by specialists dealing with partial evidence. Thus, discussions have been confined to particular academic and ...
Genetic variability, phylogenetic relationships and gene flow in Triatoma infestans dark morphs from the Argentinean Chaco
(Elsevier Science, 2011-07)
The recent discovery of sylvatic populations of Triatoma infestans outside the Andean Valleys of Bolivia prompted an evolutionary question about the putative ancestral area of origin and dispersal of the species, and an ...
Evolution of pre‐zygotic and post‐zygotic barriers to gene flow among three cryptic species within the Anastrepha fraterculus complex
(Wiley, 2013-09)
Tropical tephritids are ideally suited for studies on population divergence and speciation because they include species groups undergoing rapid radiation, in which morphologically cryptic species and sister species are ...
