Torsional resistance as a principal component of the structural design of long bones: comparative multivariate evidence in birds.
Here we study the occurrence of torsion-resisting morphological and histological features (thin bone walls, circular shaft cross-section, oblique collagen fibers, and laminar tissue arrangement) in aExpand

Bone typology and growth rate: testing and quantifying 'Amprino's rule' in the mallard (Anas platyrhynchos).
Periosteal bone histology expresses its rate of deposition. This fundamental relationship between bone structure and growth dynamics, first assumed by Amprino many decades ago, was quantified inExpand

Paleohistological estimation of bone growth rate in extinct archosaurs
Abstract The clade Archosauria contains two very different sister groups in terms of diversity (number of species) and disparity (phenotypic variation): Crurotarsi (taxa more closely related toExpand

Assessing a relationship between bone microstructure and growth rate: a fluorescent labelling study in the king penguin chick (Aptenodytes patagonicus)
SUMMARY Microstructure–function relationships remain poorly understood in primary bone tissues. The relationship between bone growth rate and bone tissue type, although documented in some species byExpand

Periosteal bone growth rates in extant ratites (ostriche and emu). Implications for assessing growth in dinosaurs.
The first quantitative experimental data on growth dynamics of the primary cortical bone of young ratites demonstrate the following. 1) From hatching to 2 months of age, cortical thickness remainsExpand

An integrative study of ageing in a wild population of common lizards
1. Integrative studies on ageing patterns in multiple traits of organisms are challenging and rare in free-living populations. However, developing integrative approaches could prove useful toExpand

The Gavialis–Tomistoma debate: the contribution of skull ontogenetic allometry and growth trajectories to the study of crocodylian relationships
SUMMARY The phylogenetic placement of Tomistoma and Gavialis crocodiles depends largely upon whether molecular or morphological data are utilized. Molecular analyses consider them as sister taxa,Expand

Phylogenetic signal in bone microstructure of sauropsids.
In spite of the fact that the potential usefulness of bone histology in systematics has been discussed for over one and a half centuries, the presence of a phylogenetic signal in the variation ofExpand

A new Transantarctic relationship: morphological evidence for a Rheidae–Dromaiidae–Casuariidae clade (Aves, Palaeognathae, Ratitae)
Although ratites have been studied in considerable detail, avian systematists have been unable to reach a consensus regarding their relationships. Morphological studies indicate a basal splitExpand

Lines of arrested growth in bone and age estimation in a small primate: Microcebus murinus
Abstract In primates, age determination using lines of arrested growth (LAGs) from bones has rarely been attempted, andthe reliability of these structures has never been experimentally validated. InExpand
