| delta6-desaturase sequence evidence for explosive pliocene radiations within the adaptive radiation of macaronesian echium (boraginaceae). | the oceanic islands of macaronesia provide an ideal temporal and spatial context to test hypotheses of plant evolution using a novel set of phylogenetic markers, delta(6)-desaturase sequences. in contrast to the limited resolution of standard molecular markers (nrdna and plastid sequences), the delta(6)-desaturase sequence phylogeny of echium unequivocally reconstructs its active colonization across islands and archipelagos (madeira, the canary islands, and cape verde), as well as its subsequent ... | 2009 | 19398027 |
| mitochondrial dna patterns in the macaronesia islands: variation within and among archipelagos. | macaronesia covers four atlantic archipelagos: the azores, madeira, the canary islands, and the cape verde islands. when discovered by europeans in the 15th century, only the canaries were inhabited. historical reports highlight the impact of iberians on settlement in macaronesia. although important differences in their settlement are documented, its influence on their genetic structures and relationships has yet to be ascertained. in this study, the hypervariable region i (hvri) sequence and co ... | 2010 | 19927277 |
| a new species of spauligodon (nematoda: oxyurida: pharyngodonidae) in geckos from s?o nicolau island (cape verde) and its phylogenetic assessment. | abstract a new nematode species of spauligodon, spauligodon nicolauensis n. sp. from geckos tarentola bocagei and tarentola nicolauensis on the island of s?o nicolau, cape verde, is described. the new nematode was found in the pellets obtained directly from the geckos in a non-invasive fashion and its identity was assessed both at morphologic and genetic levels. the new species has morphological similarities with spauligodon tarentolae spaul, 1926, also parasitizing geckos from the canary isla ... | 2011 | 21942458 |
