Metabolic scaling has diversified among species, despite an evolutionary constraint within species
Julian E. Beaman,Julian E. Beaman,Daniel Ortiz-Barrientos,Keyne Monro,Matthew Hall,Craig R. White +5 more
TL;DR: It is shown that ontogenetic metabolic scaling is evolutionarily constrained due to an absence of additive genetic variation in juvenile metabolic rate and mass, and that there is strong stabilising selection on combinations of mass and metabolic rate within species.
Journal ArticleDOI
Meeting review: American Genetics Association Symposium on the genetics of speciation.
TL;DR: Some of the ingredients that make nature discrete and can lead to clustering even in the presence of gene flow are discussed.

Divergence in hormone signalling links local adaptation and hybrid failure
Melanie J. Wilkinson,Federico Roda,Gregory M. Walter,Rick Nipper,Jessica J. Walsh,Scott L. Allen,Diana M. Bernal,Henry L. North,Christine A. Beveridge,Daniel Ortiz-Barrientos +9 more
TL;DR: The results suggest that divergence in hormonal pathways can create a genetic link between rapid adaptation to new environments and the evolution of intrinsic reproductive isolation in the Australian wildflower Senecio lautus.
Journal Article
A search for genetic loci involved in predisposition to bipolar mood disorder in the population of Antioquia, Colombia.
Luis Carvajal-Carmona,Jorge Ospina-Duque,Jorge Calle,Carlos López,L Ochoa,Jose Nestor M. Garcia,Daniel Ortiz-Barrientos,Nicolás Pineda,Angelica Ospina,María Stella Girón López,Aurora Gallo,Ana Miranda,M. Cuartas,Patricia Montoya,Carlos Palacio,Gabriel Bedoya,Mark I. McCarthy,Reus,N Freimer,AR Linares +19 more
TL;DR: Simulation of pedigrees from a bipolar disorder type 1 study sample from the province of Antioquia in Colombia indicates that the current power to detect a lod score greater than 1 ranges between 33 and 86%.

Evidence for mutation-order speciation between convergent ecotypes
Maria C. Melo,Maddie E. James,Federico Roda,Diana M Bernal-Franco,Melanie J. Wilkinson,Huanle Liu,Greg M. Walter,Daniel Ortiz-Barrientos +7 more
TL;DR: A comprehensive test of the ecological speciation hypothesis in an Australian wildflower where parapatric populations found in coastal sand dunes and headlands have repeatedly and independently diverged in growth habit finds that both extrinsic and intrinsic reproductive isolation evolved between prostrate Headland populations.
