On the mismatch in the strength of competition among fossil and modern species of planktonic Foraminifera
(2019-12-01)
Aim: Many clades display the macroevolutionary pattern of a negative relationship between standing diversity and diversification rates. Competition among species has been proposed as the main mechanism that explains this ...
Phylogeny and evolutionary patterns of South American octodontoid rodents
(Polish Academy of Sciences. Institute of Paleobiology, 2013-03)
Octodontoidea is the most diverse clade of hystricognath rodents, and is richly recorded in South America since at least the Oligocene. A parsimony-based morphological phylogenetic analysis of a wide range of extant and ...
Colonization of a 'Lost World': Encrustation patterns in modern subtropical brachiopod assemblages.
(Sepm-soc Sedimentary Geology, 2004-08-01)
The encrustation of Paleozoic rhynchonelliform brachiopods has been studied for decades, but modern brachiopods have not received similar scrutiny. The discovery of abundant subtropical brachiopods from the Southeast ...

Diversity of craniomandibular morphology in caviomorph rodents: an overview of macroevolutionary and functional patternsDiversidad de la morfología craneomandibular en roedores caviomorfos: una revisión de los patrones macroevolutivos y funcionales
(Sociedad Argentina para el Estudio de los Mamíferos, 2015)
La complejidad del aparato masticatorio de los roedores, vinculado no sólo a las funciones de aprehensión y masticación, sino también a diversas funciones como la excavación de túneles, hace de éste un excelente modelo ...
Evolution of diet in extant marsupials: emergent patterns from a broad phylogenetic perspective
(Wiley Blackwell Publishing, Inc, 2020-10)
Extant marsupials are highly diverse, both morphologically and ecologically. As a key ecological factor, diet has been studied in marsupials at the species level. However, a general lack of phylogenetic integration has ...
