Two-generation confirmation of crown-size body-size relationships in human beings.
Although the existence of a relationship between crown size and body size has previously been questioned 'S. M. GARN, and A. B. LEWIS, Amer Anthrop 60:894-880, 1958; H. A. BAILIT and J. S. FRIEDLAENDER, Amer Anthrop 68:665672, 1966), recent studies show that there are systematic, positive, but low-order, correlations between crown size and various body dimensions (R. FILIPSSON and L. GOLDSON, A...
متن کاملCrown size-arch space relationships during human prenatal dental development.
As shown in composite reconstructions made from optically-projected measurements of 10mu frontal maxillofacial sections of 20 histologically normal fetuses and embryos in the 70-255 mm CRL range, individual differences in relative tooth size and interdental spacing are evident by 10.5-11 weeks of gestation, and age-corrected crown-size correlations (r=0.40) approximate those in postnatal life. ...
متن کاملRelative magnitudes of crown size reduction and body size reduction in 47-trisomy G.
Since crown size reduction has been observed in 47-trisomy G (M. M. COHEN and R. A. WINER, J Dent Res 44:197-208, 1965; M. M. COHEN, S. M. GARN, and M. A. GECIAUSKAS, J Dent Res 49:460, 1970) with delayed tooth formation timing (S. M. GARN, C. W. STIMSON, and A. B. LEWIS, J Dent Res 49:640, 1970), it is useful to compare the magnitude of crown size reduction with the magnitude of body size redu...
متن کاملRelationships between body size and abundance in ecology.
Body size is perhaps the most fundamental property of an organism and is related to many biological traits, including abundance. The relationship between abundance and body size has been extensively studied in an attempt to quantify the form of the relationship and to understand the processes that generate it. However, progress has been impeded by the under appreciated fact that there are four ...
متن کاملInterspecific pairwise relationships among body size, clutch size and latitude: deconstructing a macroecological triangle in birds
A large body of research dating back to the 19th century has shown evidence for consistent relationships between ecological variables across geographical space (Lomolino et al., 2006; Gaston et al., 2008). These so-called ecogeographical ‘rules’ are often observed both within and among species and across lineages. Here we focus on three of the most familiar Department of Biology, University of ...
