Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Why the static allometry of sexually-selected traits is so variable: the importance of function.

open access: yesIntegrative and Comparative Biology, 2019
Sexually-selected traits often show positive static allometry, with large individuals bearing disproportionately large structures. But many other sexually-selected traits show isometry or even negative allometry, with trait size varying relatively little

Ontogenetic allometry of the Beagle [PDF]

open access: yesBMC Veterinary Research, 2013
AbstractBackgroundMammalian juveniles undergo dramatic changes in body conformation during development. As one of the most common companion animals, the time line and trajectory of a dog’s development and its body’s re-proportioning is of particular scientific interest. Several ontogenetic studies have investigated the skeletal development in dogs, but

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

open access: yesThe Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Length-weight relationships of marine fishes from the central Brazilian coast [PDF]

open access: yes, 2004
Parameters of the length-weight relationship are presented for 85 fish species from the marine and estuarine regions of the central Brazilian coast (latitude 13° to 23° S). Three different methods were used. A non-linear iterative process using the quasi-

Thinning Effects on the Tree Height–Diameter Allometry of Masson Pine (Pinus massoniana Lamb.)

open access: yesForests, 2019
The stem height–diameter allometric relationship is fundamental in determining forest and ecosystem structures as well as in estimating tree volume, biomass, and carbon stocks.

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

open access: yesThe Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.

Height-diameter allometry of tropical forest trees [PDF]

open access: yes, 2011
Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry.

Developmental allometry and paediatric malaria [PDF]

open access: yesMalaria Journal, 2012
تقدر منظمة الصحة العالمية أن 80 ٪ من الوفيات الناجمة عن الملاريا تحدث بين الرضع والأطفال الصغار. على الرغم من أنه ثبت منذ فترة طويلة أن الملاريا تؤثر بشكل غير متناسب على الأطفال دون سن الخامسة، إلا أن فهمنا للآليات البيولوجية الأساسية لهذا التوزيع لا يزال غير مكتمل.

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

open access: yesThe Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.
