Although the main specialized journals are nationwide read and the published projects are frequently used as design references by students at architecture schools all over Brazil, it appears to be a favor for those projects located at the southeast region. In order to investigate this initial assumption, we selected two of the most influential architectural journals, A U and Project Design magazines, focusing on visitable projects that are, therefore, capable of offering an experience for learning about architectural project. The analysis covered three years of publications in which four states in Brazil were distinguished： Sao Paulo, Rio de Janeiro, Minas Gerais and Federal District. The collected data show that the published visitable projects coincide with the economic poles around centered cities in Brazil, as well as the location of architecture schools and specialized media, becomes evident; not only because of the greater number of projects in the Sao Paulo area, but mainly because most of the published projects are located in the capitals of the analyzed poles.展开更多

However, it is not clear whether ecological contingency differentially influences likelihood of hybridization, particularly at ecological margins where parental species may exhibit reduced fitnesses. Moreover, it is unknown whether future ecosystem change will increase the prevalence of hybridization. Ficus heterostyla and F. squamosa are closely related species co-distributed from southern Thailand to southwest China where hybridization, yielding viable seeds, has been documented. As a robust test of ecological factors driving hybridization, we investigated spatial hybridization signatures based on nuclear microsatellites from extensive population sampling across a widespread contact range. Both species showed high population differentiation and strong patterns of isolation by distance. Admixture estimates exposed asymmetric interspecific gene flow.Signatures of hybridization increase significantly towards higher latitude zones, peaking at the northern climatic margins. Geographic variation in reproductive phenology combined with ecologically challenging marginal habitats may promote this phenomenon. Our work is a first systematic evaluation of such patterns in a comprehensive, latitudinally-based clinal context, and indicates that tendency to hybridize appears strongly influenced by environmental conditions. Moreover, that future climate change scenarios will likely alter and possibly augment cases of hybridization at ecosystem scales.展开更多
