The paper shows that greater intraspecific morphological variation in bulbuls predicts broader ecological niches and larger geographic ranges.

The paper critiques a study on avian palate evolution, highlighting issues with taxon sampling and morphological interpretations.

The paper examines internal wing bone structure in birds, finding that ecological factors have limited influence compared to body size, with implications for identifying flightless species in fossils.

This paper introduces a new metric, the relative homoplasy index (RHI), to quantify homoplasy in phylogenetic datasets, showing it outperforms existing methods like CI and RI.

This study identifies phylogenetically informative characters in the pectoral girdle and forelimb skeleton of extant birds, highlighting challenges in morphological phylogenetics and the utility of combining morphology with molecular data.

This study examines how recent speciation influences phylogenetic diversity patterns across tetrapod clades, finding a negative relationship between speciation rates and phylogenetic diversity.
