The scaling of eye size in adult birds: Relationship to brain, head and body sizes
نویسنده
چکیده
Birds' eyes seem often to be about as large as head size allows and brain size is taken here as a measure of the ill-defined space that is available to accommodate them. In four data sets for non-passerines eye size relates more strongly to brain size than to body mass and most non-passerine data are consistent with eye:brain (or eye:head-space) isometry. Eye:body allometry thus seems to follow from a negative head-space:body allometry. In passerines the eye:brain size correlations seem to be secondary to strong eye:body, brain:body, and perhaps therefore head-space:body correlations, a difference attributed to the passerines' greater anatomical uniformity.

Introduction Accurate estimation of the absorbed dose in radiosensitive organs, located away from the target volume during radiotherapy, is one of the main reasons for the development of reference phantoms. The International Commission on Radiological Protection (ICRP) reference phantoms can provide a more realistic view of the human anatomy in comparison with the previously used mathematical p...

Introduction: Sexual dimorphisms in biological structures such as brain and behaviour have been widely recognized in animals and humans. The purpose of this study was to examine whether there are sex differences in the size of the cerebellum with other body traits, such as the head, tail and brain. Methods: Twelve grasscutters comprising of 6 males and 6 females were used in this study. Each b...
متن کاملThe allometry and scaling of the size of vertebrate eyes
We compiled data from the literature and colleagues to examine the relationship between eye axial length and body weight for vertebrates as well as birds, mammals, reptiles, and fishes independently. After fitting the data to logarithmic and semi-logarithmic models, we found that axial length of vertebrate eyes does obey a conventional logarithmic relationship with body weight rather than a sem...
