Evidence of pathogen-induced immunogenetic selection across the large geographic range of a wild seabird
(Oxford University Press, 2020-02)
Over evolutionary time,pathogen challenge shapes theimmunephenotype of the host tobetterrespondtoanincipient threat. The extent and direction of this selection pressure depend on the local pathogen composition, which is ...
Patterns of phenotypic selection for oil and nectar in Monttea aphylla (Plantaginaceae) in a geographic mosaic of interactions with pollinators
(Elsevier Gmbh, 2017-07)
Oil-flower species are highly specialized attracting a narrow group of oil-collecting bees in contrast to nectar-flower species visited by a wide diversity of pollinators. The vast majority of the oil species lack nectar ...

Evidence of positive selection towards Zebuine haplotypes in the BoLA region of Brangus cattle
(Cambridge University Press, 2017-07)
The Brangus breed was developed to combine the superior characteristics of both of its founder breeds, Angus and Brahman. It combines the high adaptability to tropical and subtropical environments, disease resistance, and ...
Macromolecule Particle Picking and Segmentation of a KLH Database by Unsupervised Cryo-EM Image Processing
(Facultad de Medicina y Ciencia, 2019)
Segmentation is one of the most important stages in the 3D reconstruction of macromolecule structures in cryo-electron microscopy. Due to the variability of macromolecules and the low signal-to-noise ratio of the structures ...
