Genomic history of the origin and domestication of common bean unveils its closest sister species. Repositório Alice
RENDÓN-ANAYA, M.; MONTERO-VARGAS, J. M.; SABURIDO-ALVAREZ, S.; VLASOVA, A.; CAPELLA-GUTIERREZ, S.; ORDAZ-ORTIZ, J. J.; AGUILAR, O. M.; VIANELLO, R. P.; SANTALLA, M.; DELAYE, L.; GABALDÓN, T.; GEPTS, P.; WINKLER, R.; GUIGÓ, R.; DELGADO-SALINAS, A.; HERRERA-ESTRELLA, A..
Background: Modern civilization depends on only a few plant species for its nourishment. These crops were derived via several thousands of years of human selection that transformed wild ancestors into high-yielding domesticated descendants. Among cultivated plants, common bean (Phaseolus vulgaris L.) is the most important grain legume. Yet, our understanding of the origins and concurrent shaping of the genome of this crop plant is limited. Results: We sequenced the genomes of 29 accessions representing 12 Phaseolus species. Single nucleotide polymorphism-based phylogenomic analyses, using both the nuclear and chloroplast genomes, allowed us to detect a speciation event, a finding further supported by metabolite profiling. In addition, we identified ~1200...

Morphological differences in a population of Rufous-collared Sparrow (Zonotrichia capensis, Statius Müller, 1776) (Passerine, Emberizidae) at different elevations in the Tropical Andes Biota Neotropica
Busi,Ana; Cardona-Salazar,Leydy J.; Castillo,Daniela Gómez; Ossa-López,Paula A.; Rivera-Páez,Fredy A.; Vásquez,Rodrigo A.; Castaño-Villa,Gabriel J..
Abstract Populations that breed along steep elevation gradients show diverse physiological and morphological changes in response to the different environmental conditions. The latter has been discussed by Bergmann’s and Allen’s ecogeographic rules about body and appendage sizes and environmental temperature. We compared morphometric measures (mass, bill width, tarsus, wing, and tail length) of a Zonotrichia capensis population in two localities at different elevations with similar latitudes and photoperiods on the western slope of the Colombian Central Andes. We compared a Low Elevation locality (LE) at 1800 m a.s.l. and a High Elevation locality (HE) at 3853 m a.s.l. that have approximate wind speeds of 1.3 m/s and 8.4 m/s, respectively. During 12 months...

Tropical inselbergs: habitat types, adaptive strategies and diversity patterns Rev. Bras. Bot.
Porembski,Stefan.
Inselbergs are isolated rock outcrops that rise abruptly above the surrounding plains. Granitic and gneissic inselbergs are geologically and geomorphologically old and occur throughout a broad spectrum of climatic zones. They form microclimatically and edaphically dry growth sites that support a highly specialized vegetation. Based on physiognomic criteria a number of habitat types can be distinguished that are widespread on inselbergs (e.g. ephemeral flush vegetation, monocotyledonous mats, rock pools). Three hot spots of global inselberg plant diversity can be identified which are both rich in species and endemics: a) southeastern Brazil, b) Madagascar and c) southwestern Australia.
