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.

159 p, 1.7 MB Behavioral changes, ecological niches and adaptive diversification in pigeons and doves / Lapiedra i González, Oriol ; Sol, Daniel, dir. (Centre de Recerca Ecològica i Aplicacions Forestals) ; Centre de Recerca Ecològica i Aplicacions Forestals
L'extraordinària diversitat de l'ecologia, morfologia, comportament, i la riquesa d'espècies en tot l'arbre de la vida ha interessat els investigadors des de fa molt de temps. No obstant, entendre com i per què els llinatges es diversifiquen en el seu fenotip i en nombre d'espècies segueix sent un repte important en biología evolutiva. [...]
The extraordinary diversity of ecology, morphology, behavior, and species richness across the tree of life has long interested researchers. Understanding why and how lineages diversify in phenotype and species numbers remains, however, a major challenge in evolutionary biology because evolutionary diversification is a complex process influenced by a number of factors of diverse nature. [...]
