7 p, 1.5 MB Predictable evolution towards larger brains in birds colonizing oceanic islands / Sayol, Ferran (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Downing, Philip A. (Lund University. Department of Biology, Molecular Ecology and Evolution Laboratory) ; Iwaniuk, Andrew N. (University of Lethbridge. Department of Neuroscience) ; Maspons, Joan (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sol, Daniel (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Theory and evidence suggest that some selective pressures are more common on islands than in adjacent mainland habitats, leading evolution to follow predictable trends. The existence of predictable evolutionary trends has nonetheless been difficult to demonstrate, mainly because of the challenge of separating in situ evolution from sorting processes derived from colonization events.

8 p, 752.8 KB Environmental variation and the evolution of large brains in birds / Sayol, Ferran (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Maspons, Joan (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Lapiedra i González, Oriol (Harvard University.

Environmental variability has long been postulated as a major selective force in the evolution of large brains. However, assembling evidence for this hypothesis has proved difficult. Here, by combining brain size information for over 1,200 bird species with remote-sensing analyses a to estimate temporal variation in ecosystem productivity, we show that larger brains (relative to body size) are more likely to occur in species exposed to larger environmental variation throughout their geographic range.

8 p, 473.7 KB Evolutionary divergence in brain size between migratory and resident birds / Sol, Daniel (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Garcia-Forner, Núria (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Iwaniuk, Andrew (Canadian Centre for Behavioural Neuroscience) ; Davis, Katie (University of Reading.

Department of Biology) ; Székely, Tasmás (University of Bath. Department of Biology and Biochemistry)
Despite important recent progress in our understanding of brain evolution, controversy remains regarding the evolutionary forces that have driven its enormous diversification in size. Here, we report that in passerine birds, migratory species tend to have brains that are substantially smaller (relative to body size) than those of resident species, confirming and generalizing previous studies.
