Multiple founder events explain the genetic diversity and structure of the mode...
Shiposha, Valeriia; Marques, Isabel; López-Alvarez, Diana; Manzaneda, Antonio J; Hernandez, Pilar; Olonova, Marina; Catalán, PilarBackground and Aims It is accepted that contemporary allopolyploid species have originated recurrently, but very few cases have been documented using multiple natural formations of the same species. To extend our knowledge, we have investigated the multiple origins, genetic variation and structure of the allotetraploid grass Brachypodium hybridum with respect to its progenitor diploid species B. distachyon (D g...
Colonization routes, microevolutionary genetic structure and conservation conce...
Moura, Mónica; Catalán, Pilar; Brehm, António; Sequeira, Miguel Menezes dePopulation genetic structure and diversity and phylogeographical dispersal routes were assessed for the Azorean endemic grass Deschampsia foliosa using AFLP markers. This species occurs on seven islands in the archipelago and a sampling of populations from the three main geographical groups of islands was used, covering its known distribution. Principal coordinates analyses (PCoAs), Bayesian analyses and phylog...
Karyological analysis of the five native Macaronesian Festuca (Gramineae) grass...
Sequeira, Miguel Menezes de; Díaz-Pérez, Antonio; Santos-Guerra, Arnoldo; Viruel, Juan; Catalán, PilarMenezes de Sequeira, M., Díaz-Pérez, A., Santos-Guerra, A., Viruel, J. & Catalán, P. 2009. Karyological analysis of the five na tive Macaronesian Festuca (Gramineae) grasses supports a dis tinct diploid origin of two schizoendemic groups. Anales Jard. Bot. Madrid 66(1): 55-63. A karyological analysis has been conducted of all five native Macaronesian Festuca grasses belonging to fine-leaved F. subg. Festuca sec...
Multiple colonizations, in situ speciation, and volcanism-associated stepping-s...
Díaz-Pérez, Antonio; Sequeira, Miguel; Santos-Guerra, Arnoldo; Catalán, PilarWhereas examples of insular speciation within the endemic-rich Macaronesian hotspot flora have been documented, the phylogeography of recently evolved plants in the region has received little attention. The Macaronesian red fescues constitute a narrow and recent radiation of four closely related diploid species distributed in the Canary Islands (F. agustinii), Madeira (F. jubata), and the Azores (F. francoi and...
