Do pollinators simultaneously select for inflorescence size and amount of floral scents? An experimental assessment on Escallonia myrtoidea
(BLACKWELL, 2006-11)
Correlation among phenotypic traits may be explained by correlational selection, the simultaneous selection of more than one trait, or by genetic and/or developmental factors. In Escallonia myrtoidea, a tree with scented ...
Lack of phonotactic preferences of female frogs and its consequences for signal evolution
(Elsevier, 2015)
Sexual selection is one of the main evolutionary forces that drive signal evolution. In previous studies, we have found out that males of Pleurodema thaul, a frog with an extensive latitudinal distribution in Chile, emits ...

The Evolution of Modularity in the Mammalian Skull II: Evolutionary Consequences
(SPRINGER, 2009)
Changes in patterns and magnitudes of integration may influence the ability of a species to respond to selection. Consequently, modularity has often been linked to the concept of evolvability, but their relationship has ...
Optimizing Selection of Assessment Solutions for Completing Information Extraction Results
(Revista Computación y Sistemas; Vol. 17 No.2, 2013-06-07)
Abstract. Incomplete information produces serious consequences in information extraction: it increases costs and leads to problems in downstream processing. This work focuses on improving the completeness of extraction ...
